description: Distributed antennas must be phase-calibrated (phase-synchronized) for certain operations, such as reciprocity-based joint coherent downlink beamforming, to work. We use rigorous signal processing tools to analyze the accuracy of calibration protocols that are based on over-the-air measurements between antennas, with a focus on scalability aspects for large systems. We show that (i) for some who-measures-on-whom topologies, the errors in the calibration process are unbounded when the network grows; and (ii) despite that conclusion, it is optimal -- irrespective of the topology -- to solve a single calibration problem for the entire system and use the result everywhere to support the beamforming. The analyses are exemplified by investigating specific topologies, including lines, rings, and two-dimensional surfaces.

description: We have investigated the structure and electronic properties of ferrimagnetic double perovskites, A2FeReO6 (A= Ca, Sr, Ba). The A=Ba phase is cubic (Fm3m) and metallic, while the A=Ca phase is monoclinic (P21/n) and nonmetallic. 57Fe Mossbauer spectroscopy shows that iron is present mainly in the high-spin (S=5/2) Fe3+ state in the Ca compound, while it occurs in an intermediate state between high-spin Fe2+ and Fe3+ in the Ba compound. It is argued that a direct Re t2g - Re t2g interaction is the main cause for the metallic character of the Ba compound; the high covalency of Ca-O bonds and the monoclinic distortion (which lifts the degeneracy of t2g states) seem to disrupt the Re-Re interaction in the case of the Ca compound, making it non-metallic for the same electron count.

description: The origin of biological motion can be traced back to the function of molecular motor proteins. Cytoplasmic dynein and kinesin transport organelles within our cells moving along a polymeric filament, the microtubule. The motion of the myosin molecules along the actin filaments is responsible for the contraction of our muscles. Recent experiments have been able to reveal some important features of the motion of individual motor proteins, and a new statistical physical description - often referred to as ``thermal ratchets'' - has been developed for the description of motion of these molecules. In this approach the motors are considered as Brownian particles moving along one-dimensional periodic structures due to the effect of nonequilibrium fluctuations. Assuming specific types of interaction between the particles the models can be made more realistic. We have been able to give analytic solutions for our model of kinesin with elastically coupled Brownian heads and for the motion of the myosin filament where the motors are connected through a rigid backbone. Our theoretical predictions are in a very good agreement with the various experimental results. In addition, we have considered the effects arising as a result of interaction among a large number of molecular motors, leading to a number of novel cooperative transport phenomena.

description: In this paper, we examine several typical texture attributes developed in the image processing community in recent years with respect to their capability of characterizing a migrated seismic volume. These attributes are generated in either frequency or space domain, including steerable pyramid, curvelet, local binary pattern, and local radius index. The comparative study is performed within an image retrieval framework. We evaluate these attributes in terms of retrieval accuracy. It is our hope that this comparative study will help acquaint the seismic interpretation community with the many available powerful image texture analysis techniques, providing more alternative attributes for their seismic exploration.

description: We study a pure death process. At each discrete time every individual dies or not independently of each other with a constant probability. We give examples showing that in a certain limit extinction happens along a path where one and only one individual is lost at a time. We also exhibit an example for which such a path goes from infinity to 0 in a finite time. This is what we call a process implosion.

description: We obtain regular deformed D2-brane solutions with fractional D2-branes arising as wrapped D4-branes. The space transverse to the D2-brane is a complete Ricci-flat 7-manifold of G_2 holonomy, which is asymptotically conical with principal orbits that are topologically CP^3 or the flag manifold SU(3)/(U(1) x U(1)). We obtain the solution by first constructing an L^2 normalisable harmonic 3-form. We also review a previously-obtained regular deformed D2-brane whose transverse space is a different 7-manifold of G_2 holonomy, with principal orbits that are topologically S^3 x S^3. This describes D2-branes with fractional NS-NS 2-branes coming from the wrapping of 5-branes, which is supported by a non-normalisable harmonic 3-form on the 7-manifold. We prove that both types of solutions are supersymmetric, preserving 1/16 of the maximal supersymmetry and hence that they are dual to {\cal N}=1 three-dimensional gauge theories. In each case, the spectrum for minimally-coupled scalars is discrete, indicating confinement in the infrared region of the dual gauge theories. We examine resolutions of other branes, and obtain necessary conditions for their regularity. The resolution of many of these seems to lie beyond supergravity. In the process of studying these questions, we construct new explicit examples of complete Ricci-flat metrics.

description: Cet article a pour objectif d’analyser l’effet de l’investissement public sur la croissance économique dans 23 pays d’Afrique Sub-Saharienne sur la période 1988-2017. L’Afrique Sub-Saharienne est caractérisée par un niveau d’investissement faible mais à cela s’ajoute la mauvaise qualité des institutions ce qui justifie son sous-développement d’où le choix de cette région. Pour ce faire nous admettons l’hypothèse d’existence de régimes de croissances multiple, et testons si l’effet de l’investissement public sur la croissance diffère suivant le régime de croissance. Nous utilisons au modèle de mélange fini pour identifier de façon endogène des régimes de croissance et contrôler l’hétérogénéité inobservée. Les principaux résultats montrent que les pays d’Afrique Sub-Saharienne suivent deux régimes de croissance distincts dans lesquels l’effet de l’investissement public sur la croissance est positif mais diffère en ampleur. De façon spécifique, les pays à faible qualité institutionnelle sont moins enclins à suivre le régime où l’effet de l’investissement public sur la croissance est plus important. Nos résultats soulignent l’importance de l’amélioration de la qualité des institutions dans les pays d’Afrique Sub-Saharienne.
Referring academic library chat reference patrons: how subject librarians decide

Subjects: subject: Library and Information Studies

description: Purpose: The purpose of this study is to learn what factors liaison librarians in academic research libraries consider in determining whether to refer chat reference patrons to subject specialists. Design/methodology/approach: Subject specialists were asked what policies guided their decisions to refer to a specialist and then assessed unreferred chat session transcripts both within and outside their specializations to determine need for a referral. Findings: Few respondents were guided by formal policies. Contrary to an initial hypothesis, subject area was not a key factor in referring chat. A broader set of criteria included reference interviewing, provision of relevant resources and information literacy instruction. Respondents valued both the depth that subject specialists can provide to reference interactions and the ability of a skilled generalist to support information literacy. Research limitations/implications: Findings are most applicable to large, public doctoral universities with liaison librarian programs. Assignment of respondents to subject specialist categories was complicated by their broad range of background and expertise. Practical implications: The study contributes new understanding of referrals to subject specialists who have potential to guide development of formal referral policies in academic library virtual reference services. Originality/value: The study is the first empirical examination of chat reference referral decisions.

description: Irregular migration is a sensitive policy issue around the world, often exacerbated by the lack of data. In data scarce contexts, triangulation relying on multiple sources and data points is the best strategy to arrive at evidence-based decisions. We want to contribute to this process by introducing a novel method for estimating the population size of migrants lacking legal residence, combining official statistics on international migrant stock, global social media data (Facebook), and predictive analytics through machine learning algorithms. We attain estimates of the size of the irregular migrant population for the 40 largest destination countries and, for some cases, the composition of the irregular migrant population by world regions of origin and destination. The estimates we obtain are consistent with alternative benchmarks in countries with available estimates. Inconsistencies can be explained by data limitations. We discuss potential limitations of the approach and broader implications for policy and migration research.

description: Cobalt is used in Li-ion batteries, but it is expensive and could be replaced by nickel to deliver better performance at a lower cost. With this motivation, we discuss how the character of redox orbitals of LiNiO$_2$ can be ascertained through x-ray Compton scattering measurements combined with parallel first-principles simulations. Our analysis reveals the nature of hole states in Li-doped NiO resulting from the hybridization of O 2$p$ and Ni 3$d$ orbitals. Our study also gives insight into the ferromagnetic ground state and provides a pathway toward the rational design of next-generation battery materials.

description: With today's abundant streams of data, the only constant we can rely on is change. For stream classification algorithms, it is necessary to adapt to concept drift. This can be achieved by monitoring the model error, and triggering counter measures as changes occur. In this paper, we propose a drift detection mechanism that fits a beta distribution to the model error, and treats abnormal behavior as drift. It works with any given model, leverages prior knowledge about this model, and allows to set application-specific confidence thresholds. Experiments confirm that it performs well, in particular when drift occurs abruptly.

description: The dynamic charge susceptibility and the optical conductivity are calculated in the planar t-J model within the memory function method, working directly in terms of Hubbard operators. The density fluctuation spectrum consists of a damped sound-like mode for small wave vectors and a broad high energy peak ($\sim t$) for large momenta. The study of the optical conductivity shows that electron scattering from spin fluctuations leads to the Drude-frequency dependent relaxation rate which exhibits a crossover from $ω^{3/2}$ behavior at low frequencies ($ω<2|μ|$), to a linear $ω$-dependence for frequencies larger than $2|μ|$. Due to the spin-polaron nature of charge carriers, extra absorbtions arise starting at a frequency $ω\agt J$. The obtained results are in a good agreement with exact diagonalization studies.
description: A more detailed discussion on the doping dependence of the results is added. Aspects of the decoupling procedure is clarified and references is slightly modified. Accepted for publication in Phys. Rev. B

Year: 2019

description: The resolvent formulation of the Navier$\text{--}$Stokes equations gives a means for the characterization and prediction of features of turbulent flows$\text{---}$such as statistics, structures and their nonlinear interactions$\text{---}$using the singular value decomposition of the resolvent operator based on the appropriate turbulent mean, following the framework developed by McKeon & Sharma (2010). This work will describe a methodology for approximating leading resolvent (i.e., pseudospectral) modes for shear-driven turbulent flows using prescribed analytic functions. We will demonstrate that these functions, which arise from the consideration of wavepacket pseudoeigenmodes of simplified linear operators (Trefethen 2005), in particular give an accurate approximation of the class of nominally wall-detached modes that are centered about the critical layer. Focusing in particular on modeling wall-normal vorticity modes, we present a series of simplifications to the governing equations that result in scalar differential operators that are amenable to such analysis. We demonstrate that the leading wall-normal vorticity response mode for the full Navier$\text{--}$Stokes equations may be accurately approximated by considering a second order scalar operator, equipped with a non-standard inner product. The variation in mode shape as a function of wavenumber and Reynolds number may be captured by evolving a low dimensional differential equation in parameter space. This characterization provides a theoretical framework for understanding the origin of observed structures, and allows for rapid estimation of dominant resolvent mode characteristics without the need for operator discretization or large numerical computations. We relate our findings to classical lift-up and Orr amplification mechanisms in shear-driven flows.

description: The performance of an aircraft, especially military platforms, over unpaved runways is of great importance and strategic for the success of any air force operations during war and peace scenarios. This work has the objective of showing flight test results analysis of take-off and braking performance over unpaved runways with and without vegetation. The physical phenomenon behind the increase of the rolling resistance when performing a take-off over unpaved runway is explained by introducing the concepts behind the compactation drag of the aircraft tyres when compressing the soil, besides the bulldozing effect and its correlation to the soil mechanical properties. The existing models for unpaved rolling resistance modelling, derived based on soil mechanics concepts, the Bekker and more recently Grahm models, will be presented and their limitations and difficulties on predicting aircraft behaviour will be outlined. The California Bearing Ratio (CBR) and the Cone Index (CI) are introduced as the most common methods for assessing the unpaved runway state, and these indexes will be used to correlate the aircraft behaviour with the soil characteristics. The aircraft rolling and braking resistance coefficients over soil with and without vegetation are showed as a function of the measured CBR along the runway and the vegetation effect will be outlined due to its distinct results when compared with the resistance over soils without vegetation. Other effects of parameters such as aircraft weight, tyre pressure and runway rutting are calculated and their impacts are measured. To conclude, a method based on dimensional analysis, using the Buckingham theorem is proposed as a way to generalize the results and develop a methodology to aid tests planning and results prediction.

description: The extended and standard t-J models are computationally studied on ladders and planes, with emphasis on the small J/t region. At couplings compatible with photoemission results for undoped cuprates, half-doped stripes separating $π$-shifted antiferromagnetic (AF) domains are found, as in Tranquada's interpretation of neutron experiments. Our main result is that the elementary stripe `"building-block" resembles the properties of $one$ hole at small J/t, with robust AF correlations across-the-hole induced by the local tendency of the charge to separate from the spin (G. Martins {\it et al.}, Phys. Rev. B{\bf 60}, R3716 (1999)). This suggests that the seed of half-doped stripes already exists in the unusual properties of the insulating parent compound.

description: Detailed experimental investigations of thermal and magnetic properties are presented for Cu(NH3)4SO4.H2O, an ideal uniform Heisenberg spin half chain compound. A comparison of these properties with relevant spin models is also presented. The temperature dependent magnetic susceptibility and specific heat data has been compared with the exact solution for uniform Heisenberg chain model derived by means of Bethe ansatz technique. Field dependent isothermal magnetization curves are simulated by Quantum Monte Carlo technique and compared with the corresponding experimental ones. Specific heat as a function of magnetic field (up to 7T) and temperature (down to 2K) is reported. Subsequently, the data are compared with the corresponding theoretical curves for the infinite Heisenberg spin half chain model with J=6K. Moreover, internal energy and entropy are calculated by analyzing the experimental specific heat data. Magnetic field and temperature dependent behavior of entropy and internal energy are in good agreement with the theoretical predictions.

description: In the validated SiD design, the electromagnetic calorimeter (ECal) barrel sits between the silicon tracker and the hadron calorimeter (HCal), at an inner radius of 1264 mm from the interaction point with a z extent of 3.53 m. It is made of twelve trapezoidal modules that extend the full z length of the detector. These modules have a small inner angle of 30o and overlapping ends to avoid projective cracks through the detector. This creates an asymmetric structure that is periodic in increments of π/6 radians. The effect of this structure on potential physics measurements is considered.
Anisotropic Superconductors Between Types I and II

description: Self-duality or matching between the magnetic and condensate characteristic lengths is a fundamental property of isotropic superconductors at the critical Bogomolnyi point (B-point). The self-dual state of the condensate is infinitely degenerate, which is the core reason for the sharp transition between the superconductivity types in the nearest vicinity of the critical temperature T_c. Below T_c non-local interactions in the condensate remove the degeneracy, which leads to the appearance of a finite intertype (IT) domain between types I and II. This domain exhibits the mixed state with exotic field-condensate configurations and non-standard magnetic response, which cannot be understood within the dichotomy of the conventional superconductivity types. At a first glance, this picture does not apply to an anisotropic system because no spatial matching between the condensate and magnetic field can be generally expected for direction-dependent characteristic lengths. However, contrary to these expectations, here we demonstrate that anisotropic superconductors follow the same scenario of the interchange between types I and II. In anisotropic materials the IT domain is governed by the B-point of the effective isotropic model obtained by the appropriate scaling transformation of the initial anisotropic formalism. This transformation depends on the direction of the applied magnetic field, and thus the superconductivity type of strongly anisotropic materials can be dependent on this direction.

description: We show how a novel application of the theory of anelasticity unifies the observed dynamics and proposed models of administered-rate products. This theory yields a straightforward approach to rate model construction that we illustrate by simulating the observed relaxation dynamics of two administered rate products. We also demonstrate how the use of this formalism leads to a natural definition of market friction.

Interacting electrons in magnetic fields: Tracking potentials and Jastrow-product wavefunctions

description: The Schrodinger equation for an interacting spinless electron gas in a nonuniform magnetic field admits an exact solution in Jastrow product form when the fluctuations in the magnetic field track the fluctuations in the scalar potential. For tracking realizations in a two-dimensional electron gas, the degeneracy of the lowest Landau level persists, and the ``tracking'' solutions span the ground state subspace. In the context of the fractional quantum Hall problem, the Laughlin wave function is shown to be a tracking solution. Tracking solutions for screened Coulomb interactions are also constructed. The resulting wavefunctions are proposed as variational wave functions with potentially lower energy in the case of non-negligible Landau level mixing than the Laughlin function.

description: We obtain finite parts (as well as $ε$-pole parts) of massive three-loop vacuum diagrams with three-point and/or four-point interaction vertices by reducing them to tetrahedron diagrams with both massive and massless lines, whose finite parts were given analytically in a recent paper by Broadhurst. In the procedure of reduction, the method of integration-by-parts recurrence relations is employed. We use our result to compute the $\bar{\rm MS}$ effective potential of the massive $ϕ^4$ theory.

Direct three-dimensional measurement of refractive index via dual photon-phonon scattering

Publisher: name: arXiv
Year: 2019
Subjects: subject: Optics (physics.optics)

description: We developed a microscopy technique that can measure the local refractive index without sampling the optical phase delay of the electromagnetic radiation. To do this, we designed and experimentally demonstrated a setup with two co-localized Brillouin scattering interactions that couple to a common acoustic phonon axis; in this scenario, the ratio of Brillouin frequency shifts depends on the refractive index, but not on any other mechanical and/or optical properties of the sample. Integrating the spectral measurement within a confocal microscope, the refractive index is mapped at micron-scale three-dimensional resolution. As the refractive index is probed in epi-detection and without assumptions on the geometrical dimensions of the sample, this method may prove useful to characterize biological cells and tissues.

description: Two component superlattice film of 2N layers is considered and dimensionally quantised spectrum of phonon-s is found. The problem of localization of phonon-s in the superlattice with random thicknesses of the layers is investigated. The Landauer resistance of the transport of phonon-s is calculated exactly. For short range disorder the numerical analyses shows, that at frequency ω=0, there is delocalized state and the correlation length index νis equal to 2.

calorimetery

description: The validated SiD design includes an electromagnetic calorimeter (ECal) that features twelve identical trapezoidal modules with overlapping ends that eliminate projective cracks (the darker, inner calorimeter of Fig 1). At normal incidence, the ECal contains 26 X0 of tungsten alloy absorber for an extent of 13.9 mm beginning 1.264 m from the interaction point. Photons and electrons create electromagnetic showers within the calorimeter, but a small portion of the shower is scattered off the calorimeter’s edge and deflected. This is known as “backscatter”. As the shower progresses through the calorimeter, its width increases due to contributions of low-energy particles leading to “shower spreading”. These two effects are investigated here.

Probing higher OAM of LG beams via diffraction through translated single slit

description: Laguerre-Gaussian (LG) beams carry orbital angular momentum (OAM) as a consequence of a singularity in their phase profile. In this work, we probe the OAM of LG beams using a movable single slit. We invoke the method of stationary phase to determine the resulting diffraction pattern for different topological charges, observe how these patterns changes when the slit is moved transversely and show that by looking at the resulting diffraction pattern for different slit positions, we can determine the orbital angular momentum of the incoming beam. Using a digital micromirror device (DMD) as a dynamic slit, we were able to access higher $\ell$ that were not possible in previous works involving slit diffraction. Our results are valuable in the study of OAM specially for beams where the current technology for detection is not yet mature, for example, beams whose wavelengths are in the terahertz regime or beams of higher energy such as, electron vortex beams.
Analyzing the coupling process of distributed mixed real-virtual prototypes

description: The ongoing connection and automation of vehicles leads to a closer interaction of the individual vehicle components, which demands for consideration throughout the entire development process. In the design phase, this is achieved through co-simulation of component models. However, complex co-simulation environments are rarely (re-)used in the verification and validation phases, in which mixed real-virtual prototypes (e.g. Hardware-in-the-Loop) are already available. One reason for this are coupling errors such as time-delays, which inevitably occur in co-simulation of virtual and real-time systems, and which influence system behavior in an unknown and generally detrimental way. This contribution introduces a novel, adaptive method to compensate for constant time-delays in potentially highly nonlinear, spatially distributed mixed real-virtual prototypes, using small feedforward neural networks. Their optimal initialization with respect to defined frequency domain features results from a-priori frequency domain analysis of the entire coupled system, including coupling faults and compensation methods. A linear and a nonlinear example demonstrate the method and emphasize its suitability for nonlinear systems due to online training and adaptation. As the compensation method requires knowledge only of the bandwidths, the proposed method is applicable to distributed mixed real-virtual prototypes in general.
