description: Iterative methods that calculate their steps from approximate subgradient directions have proved to be useful for stochastic learning problems over large and streaming data sets. When the objective consists of a loss function plus a nonsmooth regularization term whose purpose is to induce structure in the solution, the solution often lies on a low-dimensional manifold of parameter space along which the regularizer is smooth. (When an l1 regularizer is used to induce sparsity in the solution, for example, this manifold is defined by the set of nonzero components of the parameter vector.) This paper shows that a regularized dual averaging algorithm can identify this manifold, with high probability, before reaching the solution. This observation motivates an algorithmic strategy in which, once an iterate is suspected of lying on an optimal or near-optimal manifold, we switch to an “local phase” algorithm that searches in this manifold, thus converging rapidly to a near-optimal point. Computational results are presented to verify the identification property and to illustrate the effectiveness of this approach.

description: Recent HESS observations of the ~200 pc scale diffuse gamma-ray emission from the central molecular zone (CMZ) suggest the presence of a PeV cosmic-ray accelerator (PeVatron) located in the inner 10 pc region of the Galactic Center. Interestingly, the gamma-ray spectrum of the point-like source (HESS J1745-290) in the Galactic Center shows a cutoff at ~10 TeV, implying a cutoff around 100 TeV in the cosmic-ray proton spectrum. Here we propose that the gamma-ray emission from the inner and the outer regions may be explained self-consistently by run-away protons from a single, yet fading accelerator. In this model, gamma rays from the CMZ region are produced by protons injected in the past, while gamma rays from the inner region are produced by protons injected more recently. We suggest that the blast wave formed in a tidal disruption event (TDE) caused by the supermassive black hole (Sgr A*) could serve as such a fading accelerator. With typical parameters of the TDE blast wave, gamma-ray spectra of both the CMZ region and HESS J1745-290 can be reproduced simultaneously. Meanwhile, we find that the cosmic-ray energy density profile in the CMZ region may also be reproduced in the fading accelerator model when appropriate combinations of the particle injection history and the diffusion coefficient of cosmic rays are adopted.

description: EMulate Therapeutics, Inc. (EMTx) has developed a technology to deliver time-varying magnetic fields as WAV files, emitted in the extremely low through the low spectrum of radio frequencies (DC to 22 kHz), that can be applied to regulate pain sensation. These low power fields (~30-70 milli-Gauss AC RMS) are delivered via a portable, light-weight wearable device (Voyager). A contract third-party animal research organization (ANS Biotech, S.A.) specializing in validated rat pain models, ran the studies independently of the authors. Here we report that a subset of signals demonstrated a statistically significant effect in reducing the sensation of pain in rat models for visceral pain, neuropathic pain and inflammatory pain. Furthermore, removing frequencies above 6 kHz in the original signals improve the pain reducing effects of the unmodified signal.

description: The explicit breaking of chiral symmetry of the Wilson fermion action results in additive quark mass renormalization. Moreover, flavour singlet and non-singlet scalar currents acquire different renormalization constants with respect to continuum regularization schemes. This complicates keeping the renormalized strange quark mass fixed when varying the light quark mass in simulations with $N_f=2+1$ sea quark flavours. Here we present and validate our strategy within the CLS (Coordinated Lattice Simulations) effort to achieve this in simulations with non-perturbatively order-$a$ improved Wilson fermions. We also determine various combinations of renormalization constants and improvement coefficients.

description: In the Atlantic Rainforest of the Parque Estadual da Serra do Tabuleiro, state of Santa Catarina, southern Brazil, we found Rhinella abei (Bufonidae) infested by leeches (Hirudinoidea). We captured 27 toads on the margin of a lagoon both inside and outside water in a survey carried out during one night, and 13 of which had a total of 30 leeches (mean intensity of infestation = 2.3 ± 1.3). We did not observe wounds, scars and/or hemorrhages caused by the leeches on the toads examined, no hemorrhaging after the removal of the leeches, and the leeches removed from the toads were empty of blood. This evidence led us to theorize that the leeches were not parasitizing the toads but had a phoretic relationship. The leeches were found on both dorsal and ventral surfaces (13 on each) of the toads and were predominantly on the toads’ axils followed by back and thighs. The average snout-vent length of the toads was 69.2 ± 5.3 mm and their average body mass was 27.1 ± 6.9 g. The number of leeches found on a toad was not related to its snout-vent length or body mass. We are unaware of any previous records of leeches using anurans as dispersal agents, as suggested in the present study.

description: We have carried out new, high-frequency, high-time-resolution observations of the Crab pulsar. Combining these with our previous data, we characterize bright single pulses associated with the Main Pulse, both the Low-Frequency and High-Frequency Interpulses, and the two High-Frequency Components. Our data include observations at frequencies ranging from 1 to 43 GHz with time resolution down to a fraction of a nanosecond. We find at least two types of emission physics are operating in this pulsar. Both Main Pulses and Low-Frequency Interpulses, up to about 10 GHz, are characterized by nanoshot emission - overlapping clumps of narrow-band nanoshots, each with its own polarization signature. High-Frequency Interpulses, between 5 and 30 GHz, are characterized by spectral band emission - linearly polarized emission containing about 30 proportionately spaced spectral bands. We cannot say whether the longer-duration High-Frequency Component pulses are due to a scattering process, or if they come from yet another type of emission physics.
Charge-induced optical bistability in thermal Rydberg vapor

description: We investigate the phenomenon of optical bistability in a driven ensemble of Rydberg atoms. By performing two experiments with thermal vapors of rubidium and cesium, we are able to shed light onto the underlying interaction mechanisms causing such a non-linear behavior. Due to the different properties of these two atomic species, we conclude that the large polarizability of Rydberg states in combination with electric fields of spontaneously ionized Rydberg atoms is the relevant interaction mechanism. In the case of rubidium, we directly measure the electric field in a bistable situation via two-species spectroscopy. In cesium, we make use of the different sign of the polarizability for different l-states and the possibility of applying electric fields. Both these experiments allow us to rule out dipole-dipole interactions, and support our hypothesis of a charge-induced bistability.

Nuclear fragmentation and charge-exchange reactions induced by pions in the $Δ$-resonance region
Creators: name: Feng, Zhao-Qing

Year: 2016
Subjects: subject: Nuclear Theory (nucl-th)

description: Dynamics of the nuclear fragmentations and the charge exchange reactions in pion-nucleus collisions near the $Δ$(1232) resonance energies has been investigated within the Lanzhou quantum molecular dynamics (LQMD) transport model. An isospin, momentum and density-dependent pion-nucleon potential is implemented in the model, which influences the pion dynamics, in particular the kinetic energy spectra, but weakly impacts the fragmentation mechanism. The absorption process in pion-nucleon collisions to form the $Δ$(1232) resonance dominates the heating mechanism of target nucleus. The excitation energy transferred to the target nucleus increases with the pion kinetic energy and is similar for both $π^{-}$ and $π^{+}$ induced reactions. The magnitude of fragmentation of target nucleus weakly depends on the pion energy. The isospin ratio in the pion double charge exchange is influenced by the isospin ingredient of target nucleus.

iResum: a new paradigm for resumming gravitational wave amplitudes

name: Shah, Abhay G.
Publisher: name: arXiv
Year: 2016
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We introduce a new, resummed, analytical form of the post-Newtonian (PN), factorized, multipolar amplitude corrections $f_{\ell m}$ of the effective-one-body (EOB) gravitational waveform of spinning, nonprecessing, circularized, coalescing black hole binaries (BBHs). This stems from the following two-step paradigm: (i) the factorization of the orbital (spin-independent) terms in $f_{\ell m}$; (ii) the resummation of the residual spin (or orbital) factors. We find that resumming the residual spin factor by taking its inverse resummed (iResum) is an efficient way to obtain amplitudes that are more accurate in the strong-field, fast-velocity regime. The performance of the method is illustrated on the $\ell=2$ and $m=(1,2)$ waveform multipoles, both for a test-mass orbiting around a Kerr black hole and for comparable-mass BBHs. In the first case, the iResum $f_{\ell m}$'s are much closer to the corresponding "exact" functions (obtained solving numerically the Teukolsky equation) up to the light-ring, than the nonresummed ones, especially when the black-hole spin is nearly extremal. The iResum paradigm is also more efficient than including higher post-Newtonian terms (up to 20PN order): the resummed 5PN information yields per se a rather good numerical/analytical agreement at the last-stable-orbit, and a well-controlled behavior up to the light-ring. For comparable mass binaries (including the highest PN-order information available, 3.5PN), comparing EOB with Numerical Relativity (NR) data shows that the analytical/numerical fractional disagreement at merger, without NR-calibration of the EOB waveform, is generically reduced by iResum, from a $40\%$ of the usual approach to just a few percents. This suggests that EOBNR waveform models for coalescing BBHs may be improved using iResum amplitudes.

description: This research aims to evaluate the level of accessibility knowledge by student website and app (WEB&APP) developers as well as the role of education in their perceptions and usage of accessibility guidelines. It proposes an integrative theoretical framework to understand the relationship among education, WEB&APP developer knowledge, and guideline usage. The present work with results of a multivariate analysis of variance (MANOVA) and an interview data analysis indicates that WEB&APP students have a low level of guideline familiarity and education plays an important role in their perceptions and usage of those guidelines. It emphasises the importance of accessibility guideline education, personal connection with people who have disabilities in the education process, need for empathy in accessible WEB&APP design and development, as well as business values of accessible WEB&APP.

description: The nonlinear dielectric response of a lead titanate-doped lead magnesium niobate relaxor ferroelectric was studied using pseudo-stochastic binary electrical field excitation. The polarization was recorded for various pulse spacings and electrical field amplitudes. The decay of the field-polarization cross-correlation function could be accelerated by increasing the amplitude of the pulse fields. The extension of these experiments in order to record multidimensional dielectric spectra is illustrated.

description: We use the recently released cosmic chronometer data and the latest measured value of the local Hubble parameter, combined with the latest joint light curves of Supernovae Type Ia, and Baryon Acoustic Oscillation distance measurements, in order to impose constraints on the viable and most used $f(R)$ gravity models. We consider four $f(R)$ models, namely the Hu-Sawicki, the Starobinsky, the Tsujikawa, and the exponential one, and we parametrize them introducing a distortion parameter $b$ that quantifies the deviation from $Λ$CDM cosmology. Our analysis reveals that a small but non-zero deviation from $Λ$CDM cosmology is slightly favored, with the corresponding fittings exhibiting very efficient $AIC$ and $BIC$ Information Criteria values. Clearly, $f(R)$ gravity is consistent with observations, and it can serve as a candidate for modified gravity.

description: We report our observations of very bright prompt optical and reverse shock (RS) optical emission of GRB 140512A and analyze its multi-wavelength data observed with the {\em Swift} and {\em Fermi} missions. It is found that the joint optical-X-ray-gamma-ray spectrum with our first optical detection (R=13.09 mag) at $T_0+136$ seconds during the second episode of the prompt gamma-rays can be fit by a single power-law with index $-1.32\pm 0.01$. Our empirical fit to the afterglow lightcurves indicates that the observed bright optical afterglow with R=13.00 mag at the peak time is consistent with predictions of the RS and forward shock (FS) emission of external shock models. Joint optical-X-ray afterglow spectrum is well fit with an absorbed single power-law, with an index evolving with time from $-1.86\pm 0.01$ at the peak time to $-1.57\pm 0.01$ at late epoch, which could be due to the evolution of the ratio of the RS to FS emission fluxes. We fit the lightcurves with standard external models, and derive the physical properties of the outflow. It is found that the ratio $R_B\equivε_{\rm B, r}/ε_{\rm B, f}$ is 8187, indicating a high magnetization degree in the RS region. Measuring the relative radiation efficiency with $R_e\equivε_{\rm e, r}/ε_{\rm e, f}$, we have $R_e= 0.02$, implying the radiation efficiency of the RS is much lower than that in FS. We also show that the $R_B$ of GRBs 990123, 090102, and 130427A are similar to that of GRB 140512A and their apparent difference may be mainly attributed to the difference of the jet kinetic energy, initial Lorentz factor, and medium density among them.

description: Deutsche und internationale Prüfungsstandards verlangen vom Abschlussprüfer (AP) die Identifizierung und Beurteilung des Risikos von Bilanzmanipulationen im Jahresabschluss auf Abschluss- und Aussagenebene. Die konkrete Problemstellung ergibt sich für AP durch die Vorgabe der Standardgeber den Red Flag-Ansatz und das Fraud Triangle für die Beurteilung des Risikos von Bilanzmanipulationen zu nutzen, ohne ein methodisches Vorgehen zu konkretisieren. Das Ziel der Arbeit von Andreas Schiel ist es ein wissensbasiertes System (WBS) zu entwickeln, durch das das Risiko von Bilanzmanipulationen durch AP zuverlässiger und nachvollziehbarer beurteilt werden kann, als dies bisher möglich ist. Der Schwerpunkt der Arbeit liegt dabei im Aufbau einer strukturierten Wissensbasis, dem zentralen Bestandteil eines WBS. Um die Akzeptanz des zu erstellenden WBS zu erhöhen besteht es im Wesentlichen auf dem Wissen von deutschen APs, die als Experten im Bereich der Risikobeurteilung angesehen werden, basieren. Die Erstellung der Wissensbasis eines WBS zur Beurteilung des Risikos von Bilanzmanipulationen ist ein zweistufiger Prozess. Als erster Schritt wird im abgegrenzten Wissensbereich – Beurteilung des Risikos von Bilanzmanipulationen – Detailwissen erhoben. Hierfür werden mittels einer empirischen Studie Erfahrungen von deutschen APs über die Beurteilung des Risikos von Bilanzmanipulationen gesammelt. Die Identifikation von geeigneten Red Flags als wesentlicher Bestandteil der Risikobeurteilung sowie die relative Gewichtung der Red Flags stehen im Fokus der Studie. Zur Erfassung der Erfahrungen der APs wurde ein Fragebogen konzipiert und verschickt. Die auf diese Weise gesammelten Daten, die eine umfassende Vereinigung individuellen Wissens darstellen, werden analysiert und systematisch aufbereitet. Im zweiten Schritt zur Erstellung der Wissensbasis einer WBS zur Risikobeurteilung von Bilanzmanipulationen wird das erhobene Expertenwissen formalisiert. Hierfür wird das von Carl Cox entwickelte Konzept des „Scalable Monotonic Chaining“, das auf der Fuzzy-Logik basiert, verwendet.

description: Passwords remain the most common form of authentication in the digital world. People have increasing numbers of passwords, and many people undertake risky password management behaviours such as re-using passwords, writing them down and sharing them. It is unclear whether people persist in these behaviours because they do not understand the risks involved or the benefits of the behaviour outweigh the risk. Two studies investigated the relationships between people's perceptions of the risks and benefits of a range of password management behaviours and their self-reports of their likelihood of undertaking them. The first study involved 120 MTurkers in the U.S.A., the second study involved 128 respondents from 26 different countries including approximately 50% students. In both studies, respondents took rated the risks, benefits and likelihood of undertaking 15 password management behaviours. The two very different samples provided very similar results, validating our classification of password management behaviours into four components: Storing, Sharing, Loggingn and Change behaviours. Somecomponents were more affected by perceptions of the benefits, others were equally affected by the perceptions of the risks and the benefits. These results have implications for how information about risky password behaviours is presented to users and general education about password security.

description: We analyze chiral restoration within the $O(N+1)/O(N)$ Non-Linear Sigma Model for large $N$ as an effective theory for low-energy QCD at finite temperature $T$. The free energy is constructed diagramatically to ${\cal O}(TM^3)$ in the pion mass expansion, which allows to derive the quark condensate and the scalar susceptibility in the chiral limit. At this order, we do not have to deal with renormalization, neither from divergences from mass tadpoles nor from those of higher order loop contributions. Our results for the critical behaviour are consistent with expectations from lattice analysis and with previous works where the susceptibility is saturated by the thermal $f_0(500)$ pole.

description: The potential for application of magnetic skyrmions in high density storage devices provides a strong drive to investigate and exploit their stability and manipulability. Through a three-dimensional micromagnetic hysteresis study, we investigate the question of existence of skyrmions in cylindrical nanostructures of variable thickness. We quantify the applied field and thickness dependence of skyrmion states, and show that these states can be accessed through relevant practical hysteresis loop measurement protocols. As skyrmionic states have yet to be observed experimentally in confined helimagnetic geometries, our work opens prospects for developing viable hysteresis process-based methodologies to access and observe skyrmionic states.

description: We present a design for a near-ultraviolet (NUV) imaging instrument which may be flown on a range of available platforms, including high-altitude balloons, nanosatellites, or space missions. Although all current UV space missions adopt a Ritchey-Chretain telescope design, this requires aspheric optics, making the optical system complex, expensive and challenging for manufacturing and alignment. An all-spherical configuration is a cost-effective and simple solution. We have aimed for a small payload which may be launched by different platforms and we have designed a compact, light-weight payload which will withstand all launch loads. No other UV payloads have been previously reported with an all-spherical optical design for imaging in the NUV domain and a weight below 2 kg. Our main science goal is focussed on bright UV sources not accessible by the more sensitive large space UV missions. Here we discuss various aspects of design and development of the complete instrument, the structural and finite-element analysis of the system performed to ensure that the payload withstands launch-load stresses and vibrations. We expect to fly this telescope -- Lunar Ultraviolet Cosmic Imager (LUCI) -- on a spacecraft to the Moon as part of the Indian entry into Google X-Prize competition. Observations from the Moon provide a unique opportunity to observe the sky from a stable platform far above the Earth's atmosphere. However, we will explore other opportunities as well, and will fly this telescope on a high-altitude balloon later this year.

description: It is known that all modular forms on SL_2(Z) can be expressed as a rational function in eta(z), eta(2z) and eta(4z). By utilizing known theorems, and calculating the order of vanishing, we can compute the eta-quotients for a given level. Using this count, knowing how many eta-quotients are linearly independent and using the dimension formula, we can figure out a subspace spanned by the eta-quotients. In this paper, we primarily focus on the case where N=p a prime.

description: The age of identification of hearing loss in children is highly influenced by the hearing help seeking behaviour of their parents, particularly in countries without universal newborn hearing screening programs. In this study, an attempt was made to identify the factors associated with help seeking behaviour in parents of children with hearing loss, and the relationship of such factors with the age of identification of hearing loss. Focus group discussions based on the framework of health belief model were carried out. The discussions were transcribed and the transcripts were thematically analysed. Participants were 35 parents of children with hearing loss from the state of Karnataka in India. The findings revealed 30 factors related to their awareness about hearing loss, geographical location, socio-economic status, family, and society. The factors differed between early and late help seekers. Awareness, accessibility, and affordability are the key factors that influenced the hearing help seeking behaviour of the participants. Effective public awareness programs, newborn hearing screening programs, and provisions to make hearing healthcare affordable to all can reduce the age of identification of paediatric hearing loss in India.

Delta(54) flavor phenomenology and strings

description: Delta(54) can serve as a flavor symmetry in particle physics, but remains almost unexplored. We show that in a classification of semi-realistic Z3xZ3 heterotic string orbifolds, Delta(54) turns out to be the most natural flavor symmetry, providing additional motivation for its study. We revisit its phenomenological potential from a low-energy perspective and subject to the constraints of string models. We find a model with Delta(54) arising from heterotic orbifolds that leads to the Gatto-Sartori-Tonin relation for quarks and charged-leptons. Additionally, in the neutrino sector, it leads to a normal hierarchy for neutrino masses and a correlation between the reactor and the atmospheric mixing angles, the latter taking values in the second octant and being compatible at three sigmas with experimental data.

description: To examine risky leisure noise exposure from listening to music via headphones and to identify potential determinants with special focus on portable listening devices (PLDs) among adolescents over a period of 7.5-years. Data were collected by questionnaires at four equidistant time points (O1-O4). Music exposure via headphones was calculated based on self-reported volume setting and listening duration. Exceeding 85 dB(A) equivalent for a 40-hour working week was defined as risky noise exposure. Determinants of risky headphone and PLD exposure were investigated using generalised estimating equations and accounting for missing data by multiple imputation. Closed cohort of 2148 students attending 9th grade of any secondary school type in Regensburg (Germany), during 2009 to 2011. Risky noise exposure from headphone usage was almost twice as high in wave O1 and O2 (at age 15 or 18) compared with 20–23-year-olds in O3 and O4. Risky exposure to headphones and PLDs were associated with younger age, low and medium education, single-parent household and smoking, whereas good self-rated hearing showed a protective effect. Additionally, not being born in Germany was associated with risky PLD exposure. Before harmful behaviours become entrenched, starting preventive efforts at a young age is essential.

description: We present a set of 87 RAVE stars with detected solar like oscillations, observed during Campaign 1 of the K2 mission (RAVE K2-C1 sample). This dataset provides a useful benchmark for testing the gravities provided in RAVE Data Release 4 (DR4), and is key for the calibration of the RAVE Data Release 5 (DR5). In the present work, we use two different pipelines, GAUFRE (Valentini et al. 2013) and Sp_Ace (Boeche & Grebel 2016), to determine atmospheric parameters and abundances by fixing log(g) to the seismic one. Our strategy ensures highly consistent values among all stellar parameters, leading to more accurate chemical abundances. A comparison of the chemical abundances obtained here with and without the use of seismic log(g) information has shown that an underestimated (overestimated) gravity leads to an underestimated (overestimated) elemental abundance (e.g. [Mg/H] is underestimated by ~0.25 dex when the gravity is underestimated by 0.5 dex). We then perform a comparison between the seismic gravities and the spectroscopic gravities presented in the RAVE DR4 catalogue, extracting a calibration for log(g) of RAVE giants in the colour interval 0.50

description: We establish an energy quantization result for sequences of Willmore surfaces when the underlying sequence of Riemann surfaces is degenerating in the moduli space. we notably exhibit a new residue which quantifies the potential loss of energy in collar regions. Thanks to these residues, we also prove compactness of Willmore immersion with bounded conformal class and energy below $12π$.

The need for accurate redshifts in supernova cosmology

Publisher: name: arXiv

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

description: Recent papers have shown that a small systematic redshift shift ($Δz\sim 10^{-5}$) in measurements of type Ia supernovae can cause a significant bias ($\sim$1\%) in the recovery of cosmological parameters. Such a redshift shift could be caused, for example, by a gravitational redshift due to the density of our local environment. The sensitivity of supernova data to redshift shifts means supernovae make excellent probes of inhomogeneities. We therefore invert the analysis, and try to diagnose the nature of our local gravitational environment by fitting for $Δz$ as an extra free parameter alongside the usual cosmological parameters.

Nuclear fragmentation induced by low-energy antiprotons within a microscopic transport approach
Creators: name: Feng, Zhao-Qing
Publisher: name: arXiv
Year: 2016
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: Within the framework of the Lanzhou quantum molecular dynamics (LQMD) transport model, the nuclear fragmentation induced by low-energy antiprotons has been investigated thoroughly. A coalescence approach is developed for constructing the primary fragments in phase space. The secondary decay process of the fragments is described by the well-known statistical code. It is found that the localized energy released in antibaryon-baryon annihilation is deposited in a nucleus mainly via pion-nucleon collisions, which leads to the emissions of pre-equilibrium particles, fission, evaporation of nucleons and light fragments etc. The strangeness exchange reactions dominate the hyperon production. The averaged mass loss increases with the mass number of target nucleus. A bump structure in the domain of intermediate mass for heavy targets appears owing to the contribution of fission fragments.
