J. D. Maias, A. P. Buccino and E. Flamenco Categories: physics.ao-ph Comments: Living around Active Stars Proceedings IAU Symposium, 12 pages \\ Recently, the study of the influence of solar activity on the Earth's climate received strong attention, mainly due to the possibility, proposed by several authors, that global warming is not anthropogenic, but is due to an increase in solar activity. Although this possibility has been ruled out, there are strong evidences that solar variability has an influence on Earth's climate, in regional scales. Here we review some of these evidences, focusing in a particular aspect of climate: atmospheric moisture and related quantities like precipitation. In particular, we studied the influence of activity on South American precipitations during centuries. First, we analyzed the stream flow of the Paran\'a and other rivers of the region, and found a very strong correlation with Sunspot Number in decadal time scales. We found a similar correlation between Sunspot Number and tree-ring chronologies, which allows us to extend our study to cover the last two centuries. \\ ( https://arxiv.org/abs/1709.09170 , 3339kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09210 Date: Tue, 26 Sep 2017 18:23:30 GMT (152kb,D) Title: Electrochemical capacitance of CO-terminated Pt(111) is dominated by CO-solvent gap Authors: Ravishankar Sundararaman, Marta C. Figueiredo, Marc T. M. Koper and Kathleen A. Schwarz Categories: physics.chem-ph cond-mat.mtrl-sci Comments: 4 pages, 3 figures, 2 tables \\ The distribution of electric fields within the electrochemical double layer depends on both the electrode and electrolyte in complex ways. These fields strongly influence chemical dynamics in the electrode-electrolyte interface, but cannot be measured directly. We report experimental capacitance measurements for aqueous interfaces of CO-terminated Pt(111). By comparing these measurements with first-principles density-functional theory (DFT) calculations, we infer microscopic field distributions and decompose contributions to the inverse capacitance from various spatial regions of the interface. We find that most of the interfacial potential difference appears across the gap between the terminating O and water, and not across the CO molecule as previously hypothesized. This `gap capacitance' resulting from hydrophobic termination lowers the overall capacitance of the aqueous Pt-CO interface, and makes it less sensitive to electrolyte concentration compared to the bare metal. \\ ( https://arxiv.org/abs/1709.09210 , 152kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09212 Date: Tue, 26 Sep 2017 18:28:47 GMT (1944kb,D) Title: Deep convolutional neural networks for estimating porous material parameters with ultrasound tomography Authors: Timo L\"ahivaara, Leo K\"arkk\"ainen, Janne M.J. Huttunen, Jan S. Hesthaven Categories: physics.comp-ph \\ We study the feasibility of data based machine learning applied to ultrasound tomography to estimate water-saturated porous material parameters. In this work, the data to train the neural networks is simulated by solving wave propagation in coupled poroviscoelastic-viscoelastic-acoustic media. As the forward model, we consider a high-order discontinuous Galerkin method while deep convolutional neural networks are used to solve the parameter estimation problem. In the numerical experiment, we estimate the material porosity and tortuosity while the remaining parameters which are of less interest are successfully marginalized in the neural networks-based inversion. Computational examples confirms the feasibility and accuracy of this approach. \\ ( https://arxiv.org/abs/1709.09212 , 1944kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09230 Date: Tue, 26 Sep 2017 19:23:40 GMT (542kb,D) Title: Silent enhancement of SERS with unmodified hot spots Authors: Selen Postaci, Bilge Can Yildiz, Alpan Bek and Mehmet Emre Tasgin Categories: physics.optics Comments: 7 pages \\ Nanostructures enhance nonlinear response, such as surface enhanced Raman scattering (SERS), by localizing the incident field into hot spots. Fano resonances (FRs) in both plasmon bands, the excited one and the one Stokes shifted frequency overlaps, increase the field at the hot spots even more. This is shown to lead further enhancement of the Raman signal. However, hot spot enhancement is limited with the break-down of the molecule and the tunnelling regime. Here we show that Raman signal can be enhanced silently, without modifying the fields (by linear FRs) at the hot spots. Using a very basic model, we show that enhancement emerges due to the path interference effects in the nonlinear response. Our simulations with the exact solutions of 3D Maxwell equations show that hot spot fields are not enhanced and confirm the predictions of our simple model. A factor of 3 orders of magnitude multiplies the enhancement due to the localization. Thus, presented method can enhance SERS ~4000 times more in materials already operating in the break-down or tunneling regime. In difference to intensity enhancement with linear FRs, here, SERS can be enhanced by coupling to a same quality material via utilizing the path interferences in the nonlinear response. \\ ( https://arxiv.org/abs/1709.09230 , 542kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09233 Date: Tue, 26 Sep 2017 19:43:29 GMT (1457kb) Title: Dose Prediction with U-net: A Feasibility Study for Predicting Dose Distributions from Contours using Deep Learning on Prostate IMRT Patients Authors: Dan Nguyen, Troy Long, Xun Jia, Weiguo Lu, Xuejun Gu, Zohaib Iqbal, Steve Jiang Categories: physics.med-ph cs.AI cs.CV \\ With the advancement of treatment modalities in radiation therapy, outcomes haves greatly improved, but at the cost of increased treatment plan complexity and planning time. The accurate prediction of dose distributions would alleviate this issue by guiding clinical plan optimization to save time and maintain high quality plans. We have developed a novel application of the fully convolutional deep network model, U-net, for predicting dose from patient contours. We show that with this model, we are able to accurately predict the dose of prostate cancer patients, where the average dice similarity coefficient is well over 0.9 when comparing the predicted vs. true isodose volumes between 0% and 100% of the prescription dose. The average differences in mean and max dose for all structures were within 2.3% of the prescription dose. \\ ( https://arxiv.org/abs/1709.09233 , 1457kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09241 Date: Tue, 26 Sep 2017 20:01:39 GMT (1077kb,D) Title: Bistability in the rotational motion of rigid and flexible flyers Authors: Yangyang Huang, Leif Ristroph, Mitul Luhar, Eva Kanso Categories: physics.flu-dyn physics.bio-ph \\ We explore the rotational stability of hovering flight. Our model is motivated by an experimental pyramid-shaped object and a computational lambda-shaped analog hovering passively in oscillating airflows; both systems have been shown to maintain rotational balance during free flight. Here, we attach the lambda-shaped flyer at its apex, allowing it to rotate freely akin to a pendulum. We find that the flyer exhibits stable concave-down and concave-up behavior. Importantly, the down and up configurations are bistable and co-exist for a range of background flow properties. We explain the aerodynamic origin of this bistability and compare it to the inertia-induced stability of an inverted pendulum oscillating at its base. We then allow the flyer to flap passively by introducing a rotational spring at its apex. For stiff springs, flexibility diminishes upward stability but as stiffness decreases, a new transition to upward stability is induced by flapping. We conclude by commenting on the implications of these findings for biological and man-made aircraft. \\ ( https://arxiv.org/abs/1709.09241 , 1077kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09244 Date: Tue, 26 Sep 2017 20:03:46 GMT (484kb,D) Title: Causality and information transfer in simultaneously slow- and fast-light media Authors: Jon D. Swaim and Ryan T. Glasser Categories: physics.optics quant-ph Comments: 11 pages, 6 figures Journal-ref: Optics Express 25, 24376-24386 (2017) \\ We demonstrate the simultaneous propagation of slow- and fast-light optical pulses in a four-wave mixing scheme using warm potassium vapor. We show that when the system is tuned such that the input probe pulses exhibit slow-light group velocities and the generated pulses propagate with negative group velocities, the information velocity in the medium is nonetheless constrained to propagate at, or less than, c. These results demonstrate that the transfer and copying of information on optical pulses to those with negative group velocities obeys information causality, in a manner that is reminiscent of a classical version of the no-cloning theorem. Additionally, these results support the fundamental concept that points of non-analyticity on optical pulses correspond to carriers of new information. \\ ( https://arxiv.org/abs/1709.09244 , 484kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09257 Date: Tue, 26 Sep 2017 20:52:32 GMT (1384kb,D) Title: Phase transition of the susceptible-infected-susceptible dynamics on time-varying configuration model networks Authors: Guillaume St-Onge, Jean-Gabriel Young, Edward Laurence, Charles Murphy and Louis J. Dub\'e Categories: physics.soc-ph Comments: 13 pages, 11 figures \\ We present a degree-based theoretical framework to study the susceptible-infected-susceptible (SIS) dynamics on time-varying (rewired) configuration model networks. Using this framework, we provide a detailed analysis of the stationary state that covers, for a given structure, every dynamic regimes easily tuned by the rewiring rate. This analysis is suitable for the characterization of the phase transition and leads to three main contributions. (i) We obtain a self-consistent expression for the absorbing-state threshold, able to capture both collective and hub activation. (ii) We recover the predictions of a number of existing approaches as limiting cases of our analysis, providing thereby a unifying point of view for the SIS dynamics on random networks. (iii) We reinterpret the concept of hub-dominated phase transition. Within our framework, it appears as a heterogeneous critical phenomenon : observables for different degree classes have a different scaling with the infection rate. This leads to the successive activation of the degree classes beyond the epidemic threshold. \\ ( https://arxiv.org/abs/1709.09257 , 1384kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09293 Date: Wed, 27 Sep 2017 00:27:09 GMT (697kb) Title: Charged cell membrane in electrolyte Authors: M. Pekker, M.N. Shneider, M. Keidar Categories: physics.bio-ph \\ An effect of membrane surface charge on mechanical properties of the phospholipid bilayer membrane and pores formation is considered. It is shown that the outer and inner surfaces of the phospholipid membrane is always subject to tension, regardless of magnitude and sign of the charges on its surface. This is due to the fact that the Debye length of the extracellular and intracellular electrolyte is always much smaller than the thickness of the membrane, and accordingly the electric field on the outer surface of the membrane is always much larger than the field inside the membrane. This result contradicts the generally accepted notion that a charged phospholipid membrane is similar to a charged capacitor in a dielectric medium and it is always subject to compression. Phospholipid bilayer membrane will be subject to compression only in a very weak electrolyte (~1mM/L), when Debye length is larger than the membrane thickness. It is also shown that the membrane surface charges lead to pore compression when the pore radius is larger than the Debye radius and to the stretching in the opposite case. Difference in the coefficients of surface and edge tension of phospholipid cell membranes can be explained by taking into account the cell membrane surface charge. Simple experiments are proposed to test the influence of the cell membrane surface charge on its mechanical properties. \\ ( https://arxiv.org/abs/1709.09293 , 697kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09299 Date: Wed, 27 Sep 2017 01:21:35 GMT (2386kb,D) Title: The Angular Momentum of Topologically Structured Darkness Authors: Samuel N. Alperin, Mark E. Siemens Categories: physics.optics \\ We theoretically analyze and experimentally measure the extrinsic angular momentum contribution of topologically structured darkness found within fractional vortex beams, and show that this structured darkness can be explained by evanescent waves at phase discontinuities in the generating optic. We also demonstrate the first direct measurement of the intrinsic orbital angular momentum of light with both intrinsic and extrinsic angular momentum, and explain why the total orbital angular momenta of fractional vortices do not match the winding number of their generating phases. \\ ( https://arxiv.org/abs/1709.09299 , 2386kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09337 Date: Wed, 27 Sep 2017 05:19:45 GMT (2899kb) Title: Focusing of light energy inside a scattering medium by controlling the time-gated multiple light scattering Authors: Seungwon Jeong, Ye-Ryoung Lee, Sungsam Kang, Wonjun Choi, Jin Hee Hong, Jin-Sung Park, Yong-Sik Lim, Hong-Gyu Park, and Wonshik Choi Categories: physics.optics physics.bio-ph \\ The efficient delivery of light energy is a prerequisite for non-invasive imaging and stimulating of target objects embedded deep within a scattering medium. However, injected waves experience random diffusion by multiple light scattering, and only a small fraction reaches the target object. Here we present a method to counteract wave diffusion and to focus multiplescattered waves to the deeply embedded target. To realize this, we experimentally inject light to the reflection eigenchannels of a specific flight time where most of the multiple-scattered waves have interacted with the target object and maximize the intensity of the returning multiple-scattered waves at the selected time. For targets that are too deep to be visible by optical imaging, we demonstrated a more than 10-fold enhancement in light energy delivery in comparison with ordinary wave diffusion cases. This work will lay a foundation for enhancing the working depth of imaging, sensing, and light stimulation. \\ ( https://arxiv.org/abs/1709.09337 , 2899kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09374 Date: Wed, 27 Sep 2017 07:49:19 GMT (1151kb) Title: Magnetic properties of optimized cobalt nanospheres grown by Focused Electron Beam Induced Deposition (FEBID) on cantilever tips Authors: Soraya Sangiao, Cesar Magen, Darius Mofakhami, Gregoire de Loubens and Jose Maria De Teresa Categories: physics.app-ph cond-mat.mes-hall Comments: 23 pages, 7 figures, 1 table \\ In this work, we present a detailed investigation of the magnetic properties of cobalt nanospheres grown on cantilever tips by Focused Electron Beam Induced Deposition (FEBID). The cantilevers are extremely soft and the cobalt nanospheres are optimized for Magnetic Resonance Force Microscopy (MRFM) experiments, which implies that the cobalt nanospheres must be as small as possible while bearing high saturation magnetization. It is found that the cobalt content and the corresponding saturation magnetization of the nanospheres decrease for nanosphere diameters below 300 nm. Electron holography measurements show the formation of a magnetic vortex state in remanence, which nicely agrees with magnetic hysteresis loops performed by local magnetometry showing negligible remanent magnetization. As investigated by local magnetometry, optimal behavior for high-resolution MRFM has been found for cobalt nanospheres with diameter of $\approx$ 200 nm, which present atomic cobalt content of $\approx$ 83 at% and saturation magnetization of 106 A/m, around 70% of the bulk value. These results represent the first comprehensive investigation of the magnetic properties of cobalt nanospheres grown by FEBID for application in MRFM. \\ ( https://arxiv.org/abs/1709.09374 , 1151kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09381 Date: Wed, 27 Sep 2017 08:19:58 GMT (5344kb,D) Title: Spectral up- and downshifting of Akhmediev breathers under wind forcing Authors: D. Eeltink, A. Lemoine, H. Branger, O. Kimmoun, C. Kharif, J. Carter, A. Chabchoub, M. Brunetti, and J. Kasparian Categories: physics.flu-dyn Comments: 30 pages, 11 figures \\ We experimentally and numerically investigate the effect of wind forcing on the spectral dynamics of Akhmediev breathers, a wave-type known to model the modulation instability. We develop the wind model to the same order in steepness as the higher order modifcation of the nonlinear Schroedinger equation, also referred to as the Dysthe equation. This results in an asymmetric wind term in the higher order, in addition to the leading order wind forcing term. The derived model is in good agreement with laboratory experiments within the range of the facility's length. We show that the leading order forcing term amplifies all frequencies equally and therefore induces only a broadening of the spectrum while the asymmetric higher order term in the model enhances higher frequencies more than lower ones. Thus, the latter term induces a permanent upshift of the spectral mean. On the other hand, in contrast to the direct effect of wind forcing, wind can indirectly lead to frequency downshifts, due to dissipative effects such as wave breaking, or through amplification of the intrinsic spectral asymmetry of the Dysthe equation. Furthermore, the definitions of the up- and downshift in terms of peak- and mean frequencies, that are critical to relate our work to previous results, are highlighted and discussed. \\ ( https://arxiv.org/abs/1709.09381 , 5344kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09408 Date: Wed, 27 Sep 2017 09:25:09 GMT (41kb) Title: Relativity and Accelerator Engineering Authors: Gianluca Geloni, Vitali Kocharyan and Evgeni Saldin Categories: physics.class-ph physics.acc-ph \\ From a geometrical viewpoint, according to the theory of relativity, space and time constitute a four-dimensional continuum with pseudo-Euclidean structure. This has recently begun to be a practically important statement in accelerator physics. An X-ray Free Electron Laser (XFEL) is in fact the best, exciting example of an engineering system where improvements in accelerator technology makes it possible to develop ultrarelativistic macroscopic objects with an internal fine structure, and the theory of relativity plays an essential role in their description. An ultrarelativistic electron bunch modulated at nanometer-scale in XFELs has indeed a macroscopic finite-size of order of 10 $\mu$m. Its internal, collective structure is characterized in terms of a wave number vector. Here we will show that a four-dimensional geometrical approach, unusual in accelerator physics, is needed to solve problems involving the emission of radiation from an ultrarelativistic modulated electron beam accelerating along a curved trajectory. We will see that relativistic kinematics enters XFEL physics in a most fundamental way through the so-called Wigner rotation of the modulation wave number vector, which is closely associated to the relativity of simultaneity. If not taken into account, relativistic kinematics effects would lead to a strong qualitative disagreement between theory and experiments. In this paper, several examples of relativistic kinematics effects, which are important for current and future XFEL operation, are studied. The theory of relativity is applied by providing details of the clock synchronization procedure within the laboratory frame. This approach, exploited here but unusual in literature, is rather "practical", and should be acceptable to accelerator physicists. \\ ( https://arxiv.org/abs/1709.09408 , 41kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09421 Date: Wed, 27 Sep 2017 09:49:54 GMT (3143kb,D) Title: 'Flying Plasmons': Fabry-P\`erot Resonances in Levitated Silver Nanowires Authors: Andreas W Schell, Alexander Kuhlicke, G\"unter Kewes, Oliver Benson Categories: physics.optics \\ Plasmonic nano structures such as wire waveguides or antennas are key building blocks for novel highly integrated photonics. A quantitative understanding of the optical material properties of individual structures on the nanoscale is thus indispensable for predicting and designing the functionality of complex composite elements. In this letter we study propagating surface plasmon polaritons in single silver nanowires isolated from its environment by levitation in a linear Paul trap. Symmetry-breaking effects, e.g., from supporting substrates are completely eliminated in this way. Illuminated with white light from a supercontinuum source, Fabry-P\`erot-like resonances are observed in the scattering spectra obtained from the ends of the nanowires. The plasmonic nature of the signal is verified by local excitation and photon collection corresponding to a clean transmission measurement through a Fabry-P\`erot resonator. A numerical simulation is used to compute the complex effective refractive indices of the nanowires as input parameter for a simple Fabry-P\`erot model, which nicely reproduces the measured spectra despite the highly dispersive nature of the system. Our studies pave the way for quantitative characterization of nearly any trappable plasmonic nano object, even of fragile ones such as droplets of liquids or molten metal and of nearly any nanoresonator based on a finite waveguide with implications for modeling of complex hybrid structures featuring strong coupling or lasing. Moreover, the configuration has the potential to be complemented by gas sensors to study the impact of hot electrons on catalytic reactions nearby plasmonic particles. \\ ( https://arxiv.org/abs/1709.09421 , 3143kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09462 Date: Wed, 27 Sep 2017 12:01:14 GMT (13168kb,D) Title: Direct Statistical Simulation of Jets and Vortices in 2D Flows Authors: Steven Tobias and Brad Marston Categories: physics.flu-dyn \\ In this paper we perform Direct Statistical Simulations of a model of two-dimensional flow that exhibits a transition from jets to vortices. The model employs two-scale Kolmogorov forcing, with energy injected directly into the zonal mean of the flow. We compare these results with those from Direct Numerical Simulations. For square domains the solution takes the form of jets, but as the aspect ratio is increased a transition to isolated coherent vortices is found. We find that a truncation at second order in the equal-time but nonlocal cumulants that employs zonal averaging (zonal CE2) is capable of capturing the form of the jets for a range of Reynolds numbers as well as the transition to the vortex state, but, unsurprisingly, is unable to reproduce the correlations found for the fully nonlinear (non-zonally symmetric) vortex state. This result continues the program of promising advances in statistical theories of turbulence championed by Kraichnan. \\ ( https://arxiv.org/abs/1709.09462 , 13168kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09508 Date: Thu, 24 Aug 2017 13:44:39 GMT (335kb) Title: Is Objectivity a Useful Construct? Authors: Bruce Levinson Categories: physics.hist-ph quant-ph Comments: 15 pages \\ Humanity's efforts to transmute lead into gold have impelled civilizations. Our efforts to transmute human experience into objective laws have enjoyed similar success. Through thinkers such as Oliver Wendell Holmes, William James, Felix S. Cohen, Carol E. Cleland, Russell K. Standish and Christopher A. Fuchs we can see that a source of the difficulty in understanding phenomena via objective laws is that the law can best be understood as a quantum system, not a classical one. Law resembles a quantum system because maximal legal information is not complete and cannot be completed. \\ ( https://arxiv.org/abs/1709.09508 , 335kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09510 Date: Mon, 4 Sep 2017 13:18:18 GMT (10738kb,D) Title: Thermophysical Phenomena in Metal Additive Manufacturing by Selective Laser Melting: Fundamentals, Modeling, Simulation and Experimentation Authors: Christoph Meier and Ryan W. Penny and Yu Zou and Jonathan S. Gibbs and A. John Hart Categories: physics.app-ph cs.CE \\ Among the many additive manufacturing (AM) processes for metallic materials, selective laser melting (SLM) is arguably the most versatile in terms of its potential to realize complex geometries along with tailored microstructure. However, the complexity of the SLM process, and the need for predictive relation of powder and process parameters to the part properties, demands further development of computational and experimental methods. This review addresses the fundamental physical phenomena of SLM, with a special emphasis on the associated thermal behavior. Simulation and experimental methods are discussed according to three primary categories. First, macroscopic approaches aim to answer questions at the component level and consider for example the determination of residual stresses or dimensional distortion effects prevalent in SLM. Second, mesoscopic approaches focus on the detection of defects such as excessive surface roughness, residual porosity or inclusions that occur at the mesoscopic length scale of individual powder particles. Third, microscopic approaches investigate the metallurgical microstructure evolution resulting from the high temperature gradients and extreme heating and cooling rates induced by the SLM process. Consideration of physical phenomena on all of these three length scales is mandatory to establish the understanding needed to realize high part quality in many applications, and to fully exploit the potential of SLM and related metal AM processes. \\ ( https://arxiv.org/abs/1709.09510 , 10738kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09516 Date: Mon, 18 Sep 2017 23:17:44 GMT (732kb,D) Title: Stability of traveling, pre-tensioned, heavy cables Authors: Abhinav R.

The cable is modeled as a beam resisting bending and shear. The governing equation for the transverse in-plane vibrations of the cable are derived through the Newton-Euler method. The cable dynamics is also studied in the limit of zero bending stiffness. In all cases, application of en- ergy balance reveals that the total energy of the system fluctuates even though the oscillations are small and bounded in time, indicating that the system is nonconser- vative. A comprehensive stability analysis is carried out in the parameter space of inclination, traveling speed, pre-tension, bending rigidity and the slenderness of the cable. Effect of damping is also considered. We conclude that, while pre-tension, rigidity and slenderness enhance the stability of the traveling cable, the angle of inclination affects the stability adversely. These results may act as guidelines for safer design and operation. \\ ( https://arxiv.org/abs/1709.09516 , 732kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09517 Date: Wed, 20 Sep 2017 13:54:20 GMT (210kb) Title: Can a balance of electric and gravitational forces be achieved?

Groening, M. Chung, C. Xiao Categories: physics.acc-ph Comments: 5 pages, 3 figures \\ In 1926, H. Busch formulated a theorem for one single charged particle moving along a region with a longitudinal magnetic field [H. Busch, Berechnung der Bahn von Kathodenstrahlen in axial symmetrischen electromagnetischen Felde, Z. Phys. 81 (5) p. 974, (1926)]. The theorem relates particle angular momentum to the amount of field lines being enclosed by the particle cyclotron motion. This paper extends the theorem to many particles forming a beam without cylindrical symmetry. A quantity being preserved is derived, which represents the sum of difference of eigen-emittances, magnetic flux through the beam area, and beam rms-vorticity multiplied by the magnetic flux. Tracking simulations and analytical calculations using the generalized Courant-Snyder formalism confirm the validity of the extended theorem. The new theorem has been applied for fast modelling of experiments with electron and ion beams on transverse emittance re-partitioning conducted at FERMILAB and at GSI. \\ ( https://arxiv.org/abs/1709.09538 , 226kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09562 Date: Fri, 22 Sep 2017 18:30:43 GMT (13kb) Title: The $\tau_q$-Fourier transform: covariance and uniqueness Authors: Nikolaos Kalogeropoulos Categories: physics.gen-ph math-ph math.MP Comments: 13 pages, No figures, Standard LaTeX2e \\ We propose an alternative definition for a Tsallis entropy composition-inspired Fourier transform, which we call "$\tau_q$-Fourier transform".

As a result, the lattice Maxwell system is shown to admit a discrete local energy-momentum conservation law corresponding to the discrete space-time symmetry. These conservative properties make the discrete system an effective algorithm for numerically solving the governing differential equations on continuous space-time. Moreover, the lattice model, respecting all conservation laws and geometric structures, is as good as and probably more preferable than the continuous Maxwell model. Under the simulation hypothesis by Bostrom and in consistent with the discussion on lattice QCD by Beane et al., the two interpretations of physics laws on space-time lattice could be essentially the same. \\ ( https://arxiv.org/abs/1709.09593 , 11kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09600 Date: Wed, 27 Sep 2017 16:06:58 GMT (505kb) Title: Shell feature: a new radiomics descriptor for predicting distant failure after radiotherapy in non-small cell lung cancer and cervix cancer Authors: Hongxia Hao, Zhiguo Zhou, Shulong Li, Genevieve Maquilan, Michael R. Folkert, Puneeth Iyengar, Kenneth D. Westover, Kevin Albuquerque, Fang Liu, Hak Choy, Robert Timmerman, Lin Yang, Jing Wang Categories: physics.med-ph Comments: 12 pages,3 figures, 3 tables \\ Purpose To develop and demonstrate a novel tumor shell feature for predicting distant failure in non-small cell lung cancer (NSCLC) and cervical cancer (CC) patients. Patients and Methods The shell predictive model was constructed using pretreatment positron emission tomography (PET) images from 48 NSCLC patients received stereotactic body radiation therapy (SBRT) and 52 CC patients underwent external beam radiation therapy and concurrent chemotherapy followed with high-dose-rate intracavitary brachytherapy. A shell feature, consisting of outer voxels around the tumor boundary, was extracted from a series of axial PET slices. The hypothesis behind this feature is that non-invasive and invasive tumors may have different morphologic patterns in the tumor periphery, in turn reflecting the differences in radiological presentations in the PET images. The utility of the shell was evaluated by the support vector machine (SVM) classifier in comparison with intensity, geometry, gray level co-occurrence matrix (GLCM) based texture, neighborhood gray tone difference matrix (NGTDM) based texture, and a combination of these four features. The results were assessed in terms of accuracy, sensitivity, specificity, and the area under the receiver operating curve (AUC). Results For NSCLC, the AUC achieved by the shell feature was 0.82 while the highest AUC achieved by the other features was 0.76. Similarly, for CC, the AUC achieved by the shell feature was 0.83 while the highest AUC achieved by the other features was 0.76. Also, the difference in performance between shell and the other features was significant (P < 0.005) in all cases. Conclusions We propose a boundary-based shell feature that correlates with tumor metastasis. The shell feature showed better predictive performance than all the other features for distant failure prediction in both NSCLC and CC. \\ ( https://arxiv.org/abs/1709.09600 , 505kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09620 Date: Wed, 27 Sep 2017 16:52:20 GMT (4329kb,D) Title: A study of ancient Khmer ephemerides Authors: Fran\c{c}ois Vernotte and Satyanad Kichenassamy Categories: physics.hist-ph physics.data-an \\ We study ancient Khmer ephemerides described in 1910 by the French engineer Faraut, in order to determine whether they rely on observations carried out in Cambodia.

The modeling of the thermo-elasto-plastic material response is addressed to predict such modifications. It has been developed in a 2D plane geometry and implemented in a hydrodynamic lagrangian code. The particular case of a tightly focused laser beam in the bulk of fused silica is considered as a first application of the proposed general model. It is shown that the warm dense matter relaxation, influenced by the elasto-plastic behavior of the surrounding cold matter, generates both a strong shock and rarefaction waves. Permanent deformations appear in the surrounding solid matter if the induced stress becomes larger than the yield strength. This interaction results in the formation of a sub-micrometric cavity surrounded by an overdense area. This approach also allows one to predict regions where cracks may form. The present modeling can be used to design nano-structures induced by short laser pulses. \\ ( https://arxiv.org/abs/1709.09632 , 960kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09644 Date: Wed, 27 Sep 2017 17:29:51 GMT (2241kb) Title: Coherent structures at ion scales in fast solar wind: {\it Cluster} observations Authors: D. Perrone, O. Alexandrova, O. W. Roberts, S. Lion, C. Lacombe, A. Walsh, M. Maksimovic, I. Zouganelis Categories: physics.plasm-ph \\ We investigate the nature of magnetic turbulent fluctuations, around ion characteristic scales, in a fast solar wind stream, by using {\it Cluster} data. Contrarily to slow solar wind, where both Alfv\'enic ($\delta b_{\perp} \gg \delta b_{\parallel}$) and compressive ($\delta b_{\parallel} \gg \delta b_{\perp}$) coherent structures are observed \cite[]{per16}, the turbulent cascade of fast solar wind is dominated by Alfv\'enic structures, namely Alfv\'en vortices, with small and/or finite compressive part, with the presence also of several current sheets aligned with the local magnetic field. Several examples of vortex chains are also recognized. Although an increase of magnetic compressibility around ion scales is observed also for fast solar wind, no strongly compressive structures are found, meaning that the nature of the slow and fast winds is intrinsically different. Multi-spacecraft analysis applied to this interval of fast wind indicate that the coherent structures are almost convected by the flow and aligned with the local magnetic field, i.e. their normal is perpendicular to {\bf B}, that is consistent with a two dimensional turbulence picture. Understanding intermittency and the related generation of coherent structures could provide a key insight into the nonlinear energy transfer and dissipation processes in magnetized and collisionless plasmas. \\ ( https://arxiv.org/abs/1709.09644 , 2241kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:1709.08628 (*cross-listing*) Date: Mon, 25 Sep 2017 12:57:29 GMT (990kb,D) Title: The coalescing colony model: mean-field, scaling, and geometry Authors: Giulia Carra, Kirone Mallick, Marc Barthelemy Categories: q-bio.PE cond-mat.stat-mech physics.soc-ph Comments: Paper (6 pages, 8 figures) and Supp. Material (4 pages, 4 figures) \\ We analyze the coalescing model where a `primary' colony grows and randomly emits secondary colonies that spread and eventually coalesce with it. This model describes population proliferation in theoretical ecology, tumor growth and is also of great interest for modeling the development of cities. Assuming the primary colony to be always spherical of radius $r(t)$ and the emission rate proportional to $r(t)^\theta$ where $\theta>0$, we derive the mean-field equations governing the dynamics of the primary colony, calculate the scaling exponents versus $\theta$ and compare our results with numerical simulations. We then critically test the validity of the circular approximation and show that it is sound for a constant emission rate ($\theta=0$). However, when the emission rate is proportional to the perimeter, the circular approximation breaks down and the roughness of the primary colony can not be discarded, thus modifying the scaling exponents. \\ ( https://arxiv.org/abs/1709.08628 , 990kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09187 (*cross-listing*) Date: Tue, 26 Sep 2017 18:00:47 GMT (214kb,D) Title: Transport Coefficients from Large Deviation Functions Authors: Chloe Ya Gao and David T. Limmer Categories: cond-mat.stat-mech cond-mat.soft physics.chem-ph Comments: 11 pages, 5 figures \\ We describe a method for computing transport coefficients from the direct evaluation of large deviation function. This method is general, relying on only equilibrium fluctuations, and is statistically efficient, employing trajectory based importance sampling. Equilibrium fluctuations of molecular currents are characterized by their large deviation functions, which is a scaled cumulant generating function analogous to the free energy. A diffusion Monte Carlo algorithm is used to evaluate the large deviation functions, from which arbitrary transport coefficients are derivable. We find significant statistical improvement over traditional Green-Kubo based calculations. The systematic and statistical errors of this method are analyzed in the context of specific transport coefficient calculations, including the shear viscosity, interfacial friction coefficient, and thermal conductivity. \\ ( https://arxiv.org/abs/1709.09187 , 214kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09191 (*cross-listing*) Date: Tue, 26 Sep 2017 18:01:15 GMT (5315kb,AD) Title: Sufficient physical conditions for self-replication Authors: Sumantra Sarkar and Jeremy L. England Categories: cond-mat.soft cond-mat.stat-mech physics.bio-ph Comments: Preprint format: 12 pages, 3 figures. Supplementary Information is under the Ancillary Files ---> \\ A self-replicator is usually understood to be an object of definite form that promotes the conversion of materials in its environment into a nearly identical copy of itself. The challenge of engineering novel, micro- or nano-scale self-replicators has attracted keen interest in recent years, both because exponential amplification is an attractive method for generating high yields of specific products, and also because self-reproducing entities have the potential to be optimized or adapted through rounds of iterative selection. Substantial steps forward have been achieved both in the engineering of particular self-replicating molecules, and also in characterizing the physical basis for possible mechanisms of self-replication. At present, however, it is an open question what the sufficient physical conditions are for novel self-replicating structures to emerge from a reservoir of building blocks on a desired time-scale. Here we report progress in addressing this question. By analyzing the dynamics of a generic class of heterogeneous particle mixtures whose reaction rates emerge from basic physical interactions, we demonstrate that the spontaneous "discovery" of self-replication is controlled by relatively generic features of the chemical space, namely: the dispersion in the distribution of reaction timescales and bound-state energies. Based on this analysis, we provide quantitative criteria that may aid experimentalists in designing a system capable of producing self-replicators, and in estimating the likely timescale for exponential growth to start. \\ ( https://arxiv.org/abs/1709.09191 , 5315kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09235 (*cross-listing*) Date: Tue, 26 Sep 2017 19:49:32 GMT (2688kb,D) Title: An Atomistic Fingerprint Algorithm for Learning Ab Initio Molecular Force Fields Authors: Yu-Hang Tang, Dongkun Zhang and George Em Karniadakis Categories: cs.CE physics.chem-ph physics.comp-ph \\ Molecular fingerprints, i.e. feature vectors describing atomistic neighborhood configurations, is an important abstraction and a key ingredient for data-driven modeling of molecular energy and interatomic force. In this paper, we present a molecular fingerprint algorithm, which is robust and efficient, for fitting per-atom scalar and vector quantities. The fingerprint is essentially a continuous density field formed through the superimposition of smoothing kernels centered on the atoms. We suggest that the distance between the fingerprints be measured as a weighted L2 norm of their difference. Rotational invariance of the fingerprint is achieved by aligning, for each fingerprint instance, the neighboring atoms onto a set of local canonical coordinate frame computed from a kernel minisum optimization procedure. We show that this approach is superior over PCA-based methods especially when the atomistic neighborhood is sparse and/or contains symmetry. To minimize the computational cost, we derive numerical recipes for discrete sampling and evaluation of the fingerprint using optimal quadrature rules. We also experiment on the choice of weight functions for constructing the density fields, and characterize their performance for fitting interatomic potentials. The applicability of the fingerprint is demonstrated through a set of realistic benchmark problems. \\ ( https://arxiv.org/abs/1709.09235 , 2688kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09330 (*cross-listing*) Date: Wed, 27 Sep 2017 04:35:18 GMT (212kb,D) Title: Integral Fluctuation Theorems for Stochastic Resetting Systems Authors: Arnab Pal and Saar Rahav Categories: cond-mat.stat-mech physics.chem-ph Comments: 14 pages, 4 figures \\ We study the stochastic thermodynamics of resetting systems. Violation of microreversibility means that the well known derivations of fluctuations theorems break down for dynamics with resetting. Despite that we show that stochastic resetting systems satisfy two integral fluctuation theorems. The first is the Hatano-Sasa relation describing the transition between two steady states. The second integral fluctuation theorem involves a functional that includes both dynamical and thermodynamic contributions. We find that the second law-like inequality found by Fuchs et al. for resetting systems [EPL, 113, (2016)] can be recovered from this integral fluctuation theorem with the help of Jensen's inequality. \\ ( https://arxiv.org/abs/1709.09330 , 212kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09344 (*cross-listing*) Date: Wed, 27 Sep 2017 05:56:25 GMT (2203kb) Title: Kramers-Kronig potentials for the discrete Schr\"odinger equation Authors: Stefano Longhi Categories: quant-ph physics.optics Comments: 8 pages, 5 figures, to appear in Phys Rev A \\ In a seminal work, S.A.R. Horsley and collaborators [S.A.R.

Here we consider the scattering properties of Kramers-Kronig potentials for the discrete version of the Schr\"odinger equation, which generally describes wave transport on a lattice. Contrary to the continuous Schr\"odinger equation, on a lattice a stationary Kramers-Kronig potential is reflective. However, it is shown that a slow drift can make the potential invisible under certain conditions. \\ ( https://arxiv.org/abs/1709.09344 , 2203kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09367 (*cross-listing*) Date: Wed, 27 Sep 2017 07:33:54 GMT (306kb) Title: On the Status of the Measurement Problem: Recalling the Relativistic Transactional Interpretation Authors: R. E. Kastner Categories: quant-ph physics.hist-ph physics.pop-ph Comments: Comments and/or questions welcome \\ In view of a resurgence of concern about the measurement problem, it is pointed out that the Relativistic Transactional Interpretation (RTI) remedies issues previously considered as drawbacks or refutations of the original TI. Specifically, once one takes into account relativistic processes that are not representable at the non-relativistic level (such as particle creation and annihilation, and virtual propagation), absorption is quantitatively defined in unambiguous physical terms. RTI therefore provides a well-defined terminus to what appears to be a necessary infinite regress concerning `absorption' when only the non-relativistic level is considered. In addition, specifics of the relativistic transactional model demonstrate that the Maudlin `contingent absorber' challenge to the original TI cannot even be mounted: basic features of established relativistic field theories (in particular, the asymmetry between field sources and the bosonic fields, and the fact that slow-moving bound states, such as atoms, are not offer waves) dictate that the `slow-moving offer wave' required for the challenge scenario cannot exist. It is concluded that issues previously considered obstacles for TI are no longer legitimately viewed as such, and that reconsideration of the transactional picture is warranted in connection with solving the measurement problem. \\ ( https://arxiv.org/abs/1709.09367 , 306kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09385 (*cross-listing*) Date: Wed, 27 Sep 2017 08:38:59 GMT (5459kb,D) Title: The Deep Underground Neutrino Experiment -- DUNE: the precision era of neutrino physics Authors: Ernesto Kemp Categories: hep-ex physics.ins-det \\ The last decade was remarkable for neutrino physics. In particular, the phenomenon of neutrino flavor oscillations has been firmly established by a series of independent measurements. All parameters of the neutrino mixing are now known and we have elements to plan a judicious exploration of new scenarios that are opened by these recent advances. With precise measurements, we can test the 3-neutrino paradigm, neutrino mass hierarchy and CP asymmetry in the lepton sector. The future long-baseline experiments are considered to be a fundamental tool to deepen our knowledge of electroweak interactions. The Deep Underground Neutrino Experiment -- DUNE will detect a broad-band neutrino beam from Fermilab in an underground massive Liquid Argon Time-Projection Chamber at an L/E of about $10^3$ km / GeV to reach good sensitivity for CP-phase measurements and the determination of the mass hierarchy. The dimensions and the depth of the Far Detector also create an excellent opportunity to look for rare signals like proton decay to study violation of baryonic number, as well as supernova neutrino bursts, broadening the scope of the experiment to astrophysics and associated impacts in cosmology. In this presentation, we will discuss the physics motivations and the main experimental features of the DUNE project required to reach its scientific goals. \\ ( https://arxiv.org/abs/1709.09385 , 5459kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09415 (*cross-listing*) Date: Wed, 27 Sep 2017 09:43:34 GMT (1421kb,D) Title: High Precision Measurement of the $^{19}$Ne Half-life using real-time digital acquisition Authors: C.

The resulting half-life, $17.2569\pm0.0019_{(stat)}\pm0.0009_{(syst)}$~s, is the most precise up to now for $^{19}$Ne. It is found in agreement with two recent precise measurements and not consistent with the most recent one [L.J. Broussard {\it et al.}, Phys. Rev.

An experimental method, allowing measurements of dissipation in the system at all scales, is first introduced. Practical experimental devices for increasing the dissipation are used. The main observable consequence of increasing the damping is a significant modification in the slope of the power spectral density, so that the observed power laws are not in a pure inertial regime. However, the system still displays a turbulent behavior with a cut-off frequency that is determined by the injected power which does not depend on damping. By using the measured damping power-law in numerical simulations, similar conclusions are drawn out. \\ ( https://arxiv.org/abs/1709.09438 , 1265kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09447 (*cross-listing*) Date: Wed, 27 Sep 2017 11:04:02 GMT (3035kb,D) Title: Information processing features can detect behavioral regimes of dynamical systems Authors: Rick Quax, Gregor Chliamovitch, Alexandre Dupuis, Jean-Luc Falcone, Bastien Chopard, Alfons G. Hoekstra, Peter M.A. Sloot Categories: cs.IT math.IT physics.soc-ph \\ In dynamical systems, local interactions between dynamical units generate correlations which are stored and transmitted throughout the system, generating the macroscopic behavior. However a framework to quantify and study this at the microscopic scale is missing. Here we propose an 'information processing' framework based on Shannon mutual information quantities between the initial and future states. We apply it to the 256 elementary cellular automata (ECA), which are the simplest possible dynamical systems exhibiting behaviors ranging from simple to complex. Our main finding for ECA is that only a few features are needed for full predictability and that the 'information integration' (synergy) feature is always most predictive. Finally we apply the formalism to foreign exchange (FX) and interest-rate swap (IRS) time series data and find that the 2008 financial crisis marks a sudden and sustained regime shift (FX and EUR IRS) resembling tipping point behavior. The USD IRS market exhibits instead a slow and steady progression which appears consistent with the hypothesis that this market is (part of) the driving force behind the crisis. Our work suggests that the proposed framework is a promising way of predicting emergent complex systemic behaviors in terms of the local information processing of units. \\ ( https://arxiv.org/abs/1709.09447 , 3035kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09525 (*cross-listing*) Date: Mon, 25 Sep 2017 14:35:39 GMT (107kb) Title: Topological phase of the interlayer exchange coupling with application to magnetic switching Authors: A. Umerski Categories: cond-mat.mes-hall physics.app-ph Comments: 4 pages, 2 figures \\ We show, theoretically, that the phase of the interlayer exchange coupling (IEC) undergoes a topological change of approximately $2\pi$ as the chemical potential of the ferromagnetic (FM) lead moves across a hybridization gap (HG). The effect is largely independent of the detailed parameters of the system, in particular the width of the gap. The implication is that for a narrow gap, a small perturbation in the chemical potential of the lead can give a sign reversal of the exchange coupling. This offers the possibility of controlling magnetization switching in spintronic devices such as MRAM, with little power consumption. Furthermore we believe that this effect has already been indirectly observed, in existing measurements of the IEC as a function of temperature and of doping of the leads. \\ ( https://arxiv.org/abs/1709.09525 , 107kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09526 (*cross-listing*) Date: Wed, 27 Sep 2017 13:58:50 GMT (2048kb,D) Title: A mechanical model for diversified insect wing margin shapes Authors: Yukitaka Ishimoto, Kaoru Sugimura Categories: q-bio.TO cond-mat.soft physics.bio-ph Comments: latex 21 pages, 9 figures, pre-revised version with the same content for journal submission Journal-ref: Journal of Theoretical Biology 427 (2017) 17-27 DOI: 10.1016/j.jtbi.2017.05.026 \\ The wings in different insect species are morphologically distinct with regards to their size, outer contour (margin) shape, venation, and pigmentation. The basis of the diversity of wing margin shapes remains unknown, despite the fact that gene networks governing the Drosophila wing development have been well characterised. Among the different types of wing margin shapes, smoothly curved contour is the most frequently found and implies the existence of a highly organised, multicellular mechanical structure. Here, we developed a mechanical model for diversified insect wing margin shapes, in which non-uniform bending stiffness of the wing margin is considered. We showed that a variety of spatial distribution of the bending stiffness could reproduce diverse wing margin shapes. Moreover, the inference of the distribution of the bending stiffness from experimental images indicates a common spatial profile among insects tested. We further studied the effect of the intrinsic tension of the wing blade on the margin shape and on the inferred bending stiffness. Finally, we implemented the bending stiffness of the wing margin in the cell vertex model of the wing blade, and confirmed that the hybrid model retains the essential feature of the margin model. We propose that in addition to morphogenetic processes in the wing blade, the spatial profile of the bending stiffness in the wing margin can play a pivotal role in shaping insect wings. \\ ( https://arxiv.org/abs/1709.09526 , 2048kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09575 (*cross-listing*) Date: Sat, 26 Aug 2017 03:31:29 GMT (624kb) Title: An Assessment of Data Transfer Performance for Large-Scale Climate Data Analysis and Recommendations for the Data Infrastructure for CMIP6 Authors: Eli Dart, Michael F. Wehner, Prabhat Categories: cs.DC cs.DB physics.ao-ph \\ We document the data transfer workflow, data transfer performance, and other aspects of staging approximately 56 terabytes of climate model output data from the distributed Coupled Model Intercomparison Project (CMIP5) archive to the National Energy Research Supercomputing Center (NERSC) at the Lawrence Berkeley National Laboratory required for tracking and characterizing extratropical storms, a phenomena of importance in the mid-latitudes. We present this analysis to illustrate the current challenges in assembling multi-model data sets at major computing facilities for large-scale studies of CMIP5 data. Because of the larger archive size of the upcoming CMIP6 phase of model intercomparison, we expect such data transfers to become of increasing importance, and perhaps of routine necessity. We find that data transfer rates using the ESGF are often slower than what is typically available to US residences and that there is significant room for improvement in the data transfer capabilities of the ESGF portal and data centers both in terms of workflow mechanics and in data transfer performance. We believe performance improvements of at least an order of magnitude are within technical reach using current best practices, as illustrated by the performance we achieved in transferring the complete raw data set between two high performance computing facilities. To achieve these performance improvements, we recommend: that current best practices (such as the Science DMZ model) be applied to the data servers and networks at ESGF data centers; that sufficient financial and human resources be devoted at the ESGF data centers for systems and network engineering tasks to support high performance data movement; and that performance metrics for data transfer between ESGF data centers and major computing facilities used for climate data analysis be established, regularly tested, and published. \\ ( https://arxiv.org/abs/1709.09575 , 624kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09576 (*cross-listing*) Date: Wed, 27 Sep 2017 15:17:28 GMT (796kb) Title: Self-Organization in Networks: A Data-Driven Koopman Approach Authors: Claudia Caro-Ruiz, Duvan Tellez-Castro, Andres Pavas, and Eduardo Mojica-Nava Categories: math.OC nlin.AO physics.soc-ph Comments: paper accepted in CCAC 2017 \\ Networks out of equilibrium display dynamics characterized by multiple equilibria and sudden transitions.

Presented by R. Concei\c{c}\~{a}o. 8 pages \\ We report on the behaviour of Resistive Plate Chambers (RPC) developed for muon detection in ultra-high energy cosmic ray (UHECR) experiments. The RPCs were developed for the MARTA project and were tested on field conditions. These RPCs cover an area of $1.5 \times 1.2\,{m^2}$ and are instrumented with 64 pickup electrodes providing a segmentation better than $20\,$cm. By shielding the detector units with enough slant mass to absorb the electromagnetic component in the air showers, a clean measurement of the muon content is allowed, a concept to be implemented in a next generation of UHECR experiments. The operation of a ground array detector poses challenging demands, as the RPC must operate remotely under extreme environmental conditions, with limited budgets for power and minimal maintenance. The RPC, DAQ, High Voltage and monitoring systems are enclosed in an aluminium-sealed case, providing a compact and robust unit suited for outdoor environments, which can be easily deployed and connected. The RPCs developed at LIP-Coimbra are able to operate using a very low gas flux, which allows running them for few years with a small gas reservoir. Several prototypes have already been built and tested both in the laboratory and outdoors. We report on the most recent tests done in the field that show that the developed RPCs have operated in a stable way for more than 2 years in field conditions. \\ ( https://arxiv.org/abs/1709.09619 , 3597kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09624 (*cross-listing*) Date: Wed, 27 Sep 2017 17:01:23 GMT (730kb,D) Title: LATTES: a novel detector concept for a gamma-ray experiment in the Southern hemisphere Authors: P. Assis, U. Barres de Almeida, A. Blanco, R. Concei\c{c}\~ao, B. D'Ettore Piazzoli, A. De Angelis, M. Doro, P. Fonte, L. Lopes, G. Matthiae, M. Pimenta, R. Shellard, B. Tom\'e Categories: astro-ph.IM astro-ph.HE hep-ex physics.ins-det Comments: To appear in the proceedings of the 35th International Cosmic Ray Conference (ICRC2017), Busan, South Korea. Presented by R. Concei\c{c}\~{a}o. 8 pages \\ The Large Array Telescope for Tracking Energetic Sources (LATTES), is a novel concept for an array of hybrid EAS array detectors, composed of a Resistive Plate Counter array coupled to a Water Cherenkov Detector, planned to cover gamma rays from less than 100 GeV up to 100 TeVs. This experiment, to be installed at high altitude in South America, could cover the existing gap in sensitivity between satellite and ground arrays. The low energy threshold, large duty cycle and wide field of view of LATTES makes it a powerful tool to detect transient phenomena and perform long term observations of variable sources. Moreover, given its characteristics, it would be fully complementary to the planned Cherenkov Telescope Array (CTA) as it would be able to issue alerts. In this talk, a description of its main features and capabilities, as well as results on its expected performance, and sensitivity, will be presented. \\ ( https://arxiv.org/abs/1709.09624 , 730kb) ------------------------------------------------------------------------------ \\ arXiv:1709.09661 (*cross-listing*) Date: Mon, 25 Sep 2017 22:29:45 GMT (5kb) Title: On soil activation by cosmic rays at different altitudes Authors: Yuri V. Stenkin, Oleg B. Shchegolev Categories: astro-ph.IM astro-ph.HE physics.ins-det \\ Measuring radon-due neutron flux at various altitude (100, 1000, 1700, 4300 m above sea level) we found an evidence of significant increase of radon concentration with altitude. It was also conirmed by direct radon measurements at high altitude. This allowed us to assume cosmic rays could take part in process of soil activation: they transform long-lived nuclei of uranium and thorium to nuclei with shorter life-time through specific nuclear reactions. If the resulting nuclei belong to the U-238 radioactive chain they can lead to producion of Ra-226 and then to Rn-222, thus significantly increasing its production at high altitudes where cosmic ray flux is high. \\ ( https://arxiv.org/abs/1709.09661 , 5kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:1405.3590 (*cross-listing*) replaced with revised version Wed, 27 Sep 2017 17:49:05 GMT (137kb,D) Title: EFTCAMB/EFTCosmoMC: Numerical Notes v3.0 Authors: Bin Hu, Marco Raveri, Noemi Frusciante, Alessandra Silvestri Categories: astro-ph.IM astro-ph.CO gr-qc hep-th physics.comp-ph Comments: 23 pages, 1 figure.
