description: We use the Canadian Hydrogen Intensity Mapping Experiment (CHIME) Fast Radio Burst (FRB) Project to search for FRBs that are temporally and spatially coincident with gamma-ray bursts (GRBs) occurring between 2018 July 7 and 2023 August 3. We do not find any temporal (within 1 week) and spatial (within overlapping 3 sigma localization regions) coincidences between any CHIME/FRB candidates and all GRBs with 1 sigma localization uncertainties <1 deg. As such, we use CHIME/FRB to constrain the possible FRB-like radio emission for 27 short gamma-ray bursts (SGRBs) that were within 17 deg. of CHIME/FRB's meridian at a point either 6 hrs prior up to 12 hrs after the high-energy emission. Two SGRBs, GRB 210909A and GRB 230208A, were above the horizon at CHIME at the time of their high-energy emission and we place some of the first constraints on simultaneous FRB-like radio emission from SGRBs. While neither of these two SGRBs have known redshifts, we construct a redshift range for each GRB based on their high-energy fluence and a derived SGRB energy distribution. For GRB 210909A, this redshift range corresponds to z = [0.009, 1.64] with a mean of z=0.13. Thus, for GRB 210909A, we constrain the radio luminosity at the time of the high-energy emission to L <2 x 10e46 erg s-1, L < 5 x 10e44 erg s-1, and L < 3 x 10e42 erg s-1 assuming redshifts of z=0.85, z=0.16, and z=0.013, respectively. We compare these constraints with the predicted simultaneous radio luminosities from different compact object merger models.

soppressione del rumore

description: La presente nota, prende spunto da un argomento oggetto di un seminario effettuato in DAD per gli studenti del 3° anno del corso di laurea in Tecniche Audioprotesiche (aa 2020 – '21), nel quale sono state trattate le varie strategie adottate nelle protesi acustiche per diminuire gli effetti del rumore acustico sul parlato. Ultimamente alcune di tali tecniche adottano soluzioni basate su reti neuronali e criteri di intelligenza artificiale. Prima di illustrare le varie soluzioni viene anteposta una breve descrizione delle varie tipologie di rumore, la modalità della sua stima e gli effetti che può provocare sull'apparato uditivo umano. Viene dato un cenno anche ai tentativi proposti per rendere udibili alcuni particolari segnali non verbali, cioè vari tipi di allarmi, che invece è bene non vengano attenuati.

description: Sellers of almost any product or service rarely keep their prices constant through time, and frequently offer price discounts or sales. This paper investigates an explanation of sales as a way for uninformed consumers to be willing to experience the product, and learn about its fit, and where informed consumers may forget about (or change) their preferences. We investigate the role of the rate of forgetting on the timing between sales, and of the rate of learning and menu costs on the length of a sale. We also investigate the effect of a seller carrying multiple products on the pattern of sales. Using price series from supermarket categories, and given the assumed simplified preference structure, we obtain empirical estimates of the rates of learning and forgetting, and of the other model parameters.

description: This article investigates how land-use regulations differentially influence suburban versus ruralresidential development. Particular emphasis is placed on how both the provision of municipal services (e.g., sewer and water) and zoned maximum density constrain higher-density residential development. We estimated a spatially explicit model with parcel data on recent housing development in Sonoma County, California. To account for heterogeneity in compliance with zoning regulations, we used a random-parameter logit model. The designation of sewer and water services was the most important determinant of suburban development. Meanwhile, it did not significantly affect the likelihood of rural-residential development, which actually leapfrogged into areas well beyond them.

description: This paper develops a model of residential water demand under a nonlinear budget constraint. The theoretical model for an individual consumer is adapted to yield an aggregate model that preserves the structure of the individual demand function, and that can be used with aggregate (water district level) data. The model is used to study the influence of pricing and non-price conservation programs on consumption and conservation behavior in three water districts in the San Francisco Bay Area, over a 10-year period that includes both drought and normal years. Empirical results show that pricing can be effective in reducing water consumption, particularly during the annual dry season, and during longer drought episodes. The effect is mitigated when non-price conservation programs are included in the analysis. Among these, use restrictions and landscaping audits appear to be particularly effective in inducing conservation.

description: Cloud-edge collaborative computing paradigm is a promising solution to high-resolution video analytics systems. The key lies in reducing redundant data and managing fluctuating inference workloads effectively. Previous work has focused on extracting regions of interest (RoIs) from videos and transmitting them to the cloud for processing. However, a naive Infrastructure as a Service (IaaS) resource configuration falls short in handling highly fluctuating workloads, leading to violations of Service Level Objectives (SLOs) and inefficient resource utilization. Besides, these methods neglect the potential benefits of RoIs batching to leverage parallel processing. In this work, we introduce Tangram, an efficient serverless cloud-edge video analytics system fully optimized for both communication and computation. Tangram adaptively aligns the RoIs into patches and transmits them to the scheduler in the cloud. The system employs a unique ``stitching'' method to batch the patches with various sizes from the edge cameras. Additionally, we develop an online SLO-aware batching algorithm that judiciously determines the optimal invoking time of the serverless function. Experiments on our prototype reveal that Tangram can reduce bandwidth consumption and computation cost up to 74.30\% and 66.35\%, respectively, while maintaining SLO violations within 5\% and the accuracy loss negligible.

description: We present the software tool FITDisk, a precompiled-binary Windows GUI version of our smoothed particle hydrodynamics cataclysmic variable accretion disk research code. Cataclysmic variables are binary star systems in which a compact stellar remnant, typically a white dwarf star, is stripping mass from a lower-main-sequence companion star by way of an accretion disk. Typically the disk is the brightest component of the system, because the plasma is heated dramatically as it spirals down in the gravitational well of the primary white dwarf star. The shortest-period systems can display disk "superhump" oscillations driven by the rotating tidal field of the secondary star. FITDisk models these accretion disk phenomena using a fully three-dimensional hydrodynamics calculation, and data can be visualized as they are computed or stored to hard drive for later playback at a fast frame rate. Simulations are visualized using OpenGL graphics and the viewing angle can be changed interactively. Pseudo light curves of simulated systems can be plotted along with the associated Fourier amplitude spectrum. FITDisk is available for free download at www.astro.fit.edu/cv/fitdisk.html.

description: We use Legacy Survey photometric data to probe the stellar halo in multiple directions of the sky using a probabilistic methodology to identify Blue Horizontal Branch (BHB) stars. The measured average radial density profile follows a double power law in the range $ 5 < r_{gc}/{\rm kpc} < 120$, with a density break at $r_{gc}\approx20$ kpc. This description, however, falls short, depending on the chosen line-of-sight, with some regions showing no signature of a break in the profile and a wide range of density slopes, e.g. outer slope $-5.5 \lesssim α_{out} \lesssim -4$, pointing towards a highly anisotropic stellar halo. This explains in part the wide range of density profiles reported in the literature owing to different tracers and sky coverage. Using our detailed 3-D stellar halo density map, we quantify the shape of the Pisces overdensity associated with the transient wake response of the Galaxy's (dark) halo to the Large Magellanic Cloud (LMC). Measured in the LMC's coordinate system, Pisces stands above the background, is 60 degrees long and 25 degrees wide and aligned with the LMC's orbit. This would correspond to a wake width of $\sim 32$ kpc at $\sim 70$ kpc. We do not find a statistically significant signature of the collective response in density as previously reported in the literature measured with K giant stars, despite our larger numbers. We release the catalogue constructed in this study with 95,446 possible BHB stars and their BHB probability.

description: We are living in a golden age for experimental cosmology. New experiments with high accuracy precision are been used to constrain proposals of several theories of gravity, as it has been never done before. However, important roles to constrain new theories of gravity in a theoretical perspective are the energy conditions. Throughout this work, we carefully constrained some free parameters of two different families of $f(Q,T)$ gravity using different energy conditions. This theory of gravity combines the gravitation effects through the non-metricity scalar function $Q$, and manifestations from the quantum era of the Universe in the classical theory (due to the presence of the trace of the energy-momentum tensor $T$). Our investigation unveils the viability of $f(Q,T)$ gravity to describe the accelerated expansion our Universe passes through. Besides, one of our models naturally provides a phantom regime for dark energy and satisfies the dominant energy condition. The results here derived strength the viability of $f(Q,T)$ as a promising complete theory of gravity, lighting a new path towards the description of the dark sector of the Universe.

description: Heralded entangling quantum gates are an essential element for the implementation of large-scale optical quantum computation. Yet, the experimental demonstration of genuine heralded entangling gates with free-flying output photons in linear optical system, was hindered by the intrinsically probabilistic source and double-pair emission in parametric down-conversion. Here, by using an on-demand single-photon source based on a semiconductor quantum dot embedded in a micro-pillar cavity, we demonstrate a heralded controlled-NOT (CNOT) operation between two single photons for the first time. To characterize the performance of the CNOT gate, we estimate its average quantum gate fidelity of ($87.8\pm1.2$)%. As an application, we generated event-ready Bell states with a fidelity of ($83.4\pm2.4$)%. Our results are an important step towards the development of photon-photon quantum logic gates.

description: It is shown that the strangeness enhancement and the J/psi anomalous suppression patterns observed in heavy ion collisions at top SPS energy, sqrt(s)_NN = 17.2 GeV, exhibit an interesting correlation if studied as a function of the transverse size of the interaction region. The onset of both phenomena seems to occur when the size exceeds \approx 4 fm. Strangeness enhancement is defined in terms of the strangeness undersaturation factor gamma_S and J/psi anomalous suppression in terms of the deviation from the absorption expected in a purely hadronic scenario.

Forgotten reciprocity of languages of the colonizer and the colonized : Korean language study of Japanese colonial agents
Creators: name: Minami, Kiyoe
Publisher: name: University of British Columbia
Year: 2009

description: The language policy of the Japanese Government General (JGG) can be illustrated by examining the Provisions for Korean Education which were promulgated three times and revised six times between 1911 and 1943. Reflecting the intensifying nature of Japanese colonial rule, these provisions were used to justify the dominance of Japanese in school curricula over that of Korean language curricula. After the period of'quantitative expansion of assimilation education' (1910-1936) when the JGG emphasized spreading Japanese language, the JGG inaugurated the 'Campaign for the Common Use of the National Language (i.e. Japanese)'and aimed at increasing the penetration of Japanese until it permeated into every corner of Korean society. However, the result of the thirty-five long years of Japanese language policy was dissapointing for the JGG officials: Koreans with Japanese language ability remained less than 20% in 1945. Thus, for smoother and more effective control over the colony, the JGG found it necessary for its agents to know Korean. In particular, the outbreak of the March Tl Independence Movement in 1919 triggered a more serious effort on the part of colonial agents to learn Korean. In 1921, the JGG announced Provisions for Korean Language Encouragement that inaugurated the comprehensive Korean language encouragement exam system, featuring high bonus income for the exam graduates. This JGG Korean language encouragement policy created a quiet enthusiasm among the JGG agents. The vast majority of those taking the exam and graduating came from the JGG police: i.e., from those who stood on the frontline of the Japanese colonial regime and most keenly felt the need to speak Korean in their everyday duties. This secret enthusiasm to learn Korean language study was advocated and supported by Japanese and Korean intellectuals and linguists, who expressed their collaborative efforts in numerous language guides during the colonial period. While the earlier publications tended to be disorganized and on a smaller-scale, they became more comprehensive in the 1920's, resulting in the creation of the monthly journal Choosengo in 1925. The wide coverage of JGG Korean language training provided by Choosengo reveals the diverse strata among Korean language learners and instructors at the time. Throughout the period, JGG-led Korean language study projects and guides received the support and interest of many high-profile Korean and Japanese figures, as well as numerous Korean civilians who contributed to Korean language study by Japanese colonial agents. This demonstrates that in reality, linguistic collaboration between Korean and Japanese was much more pervasive than it is generally believed today. This disproves the one-dimensional narrative that many South Korean linguists have concerning their colonial language activities.

description: Context: Open public data enable different stakeholders to perform analysis and uncover information from different perspectives. The identification and analysis of data from prison systems is not a trivial task. It raises the need for the research community to know how these data have been produced and used. Goal: Analyze prison systems data for the purpose of characterizing its use with respect to data sources, purpose and availability. Method: We performed a systematic mapping on existing evidence on prison systems original data from peer-reviewed studies published between 2000 and 2019. Results: Out of the 531 records, 196 articles were selected from the literature. Conclusion: The vast majority of the analyzed papers (75%) used restricted data. Only 18 studies (9%) provided data, which hampers replication initiatives. This indicates the need to analyze prison system in an integrated fashion, in which multidisciplinary and transparency are relevant issues to consider in such studies.

description: In 1976, Deligne and Lusztig realized the representation theory of finite groups of Lie type inside étale cohomology of certain algebraic varieties. Recently, a $p$-adic version of this theory started to emerge: there are $p$-adic Deligne-Lusztig spaces, whose cohomology encodes representation theoretic information for $p$-adic groups - for instance, it partially realizes local Langlands correspondence with characteristic zero coefficients. However, the parallel case of coefficients of positive characteristic $\ell \neq p$ has not been inspected so far. The purpose of this article is to initiate such an inspection. In particular, we relate cohomology of certain $p$-adic Deligne-Lusztig spaces to Vignéras's modular local Langlands correspondence for $\mathbf{GL}_n$.

description: We have used long-baseline near-IR interferometry to resolve the peculiar eruptive variable V838 Mon and to provide the first direct measurement of its angular size. Assuming a uniform disk model for the emission we derive an apparent angular diameter at the time of observations (November-December 2004) of $1.83 \pm 0.06$ milli-arcseconds. For a nominal distance of $8\pm2$ kpc, this implies a linear radius of $1570 \pm 400 R_{\odot}$. However, the data are somewhat better fit by elliptical disk or binary component models, and we suggest that the emission may be strongly affected by ejecta from the outburst.

First, we recover the bounds based on the individual sample mutual information from Bu et al. [2] and on a random subset of the dataset from Negrea et al. [3]. Then, we introduce their new, analogous bounds in the randomized subsample setting from Steinke and Zakynthinou [4], and we identify some limitations of the framework. Finally, we extend the bounds from Haghifam et al. [5] for Langevin dynamics to stochastic gradient Langevin dynamics and we refine them for loss functions with potentially large gradient norms.

Turbulence revealed by wavelet transform: power spectrum and intermittency for the velocity field of the cosmic baryonic fluid

description: We use continuous wavelet transform techniques to construct the global and environment-dependent wavelet statistics, such as energy spectrum and kurtosis, to study the fluctuation and intermittency of the turbulent motion in the cosmic fluid velocity field with the IllustrisTNG simulation data. We find that the peak scale of the energy spectrum define a characteristic scale, which can be regarded as the integral scale of turbulence, and the Nyquist wavenumber can be regarded as the dissipation scale. With these two characteristic scales, the energy spectrum can be divided into the energy-containing range, the inertial range and the dissipation range of turbulence. The wavelet kurtosis is an increasing function of the wavenumber $k$, first grows rapidly then slowly with $k$, indicating that the cosmic fluid becomes increasingly intermittent with $k$. In the energy-containing range, the energy spectrum increases significantly from $z = 2$ to $1$, but remains almost unchanged from $z = 1$ to $0$. We find that both the environment-dependent spectrum and kurtosis are similar to the global ones, and the magnitude of the spectrum is smallest in the lowest-density and largest in the highest-density environment, suggesting that the cosmic fluid is more turbulent in a high-density than in a low-density environment. In the inertial range, the energy spectrum's exponent is steeper than both the Kolmogorov and Burgers exponents, indicating more efficient energy transfer compared to Kolmogorov or Burgers turbulence.

description: We examine 2D electron transport through a long narrow channel driven by an external electric field in presence of diffusive boundary scattering. At zero temperature, we derive an analytical solution of the transition from ballistic to diffusive transport if we increase the bulk disorder strength. This crossover yields characteristic current density profiles. Furthermore, we illustrate the current density in the transition from ballistic to hydrodynamic transport. This corresponds to the Gurzhi effect in the resistivity. We also study the influence of finite temperature on current densities and average current in this system. In particular, we analyze how a particular scaling law of electron-electron scattering with respect to temperature affects the current along the channel.

Measuring Feature Dependency of Neural Networks by Collapsing Feature Dimensions in the Data Manifold

Subjects: subject: Machine Learning (cs.LG)

description: This paper introduces a new technique to measure the feature dependency of neural network models. The motivation is to better understand a model by querying whether it is using information from human-understandable features, e.g., anatomical shape, volume, or image texture. Our method is based on the principle that if a model is dependent on a feature, then removal of that feature should significantly harm its performance. A targeted feature is "removed" by collapsing the dimension in the data distribution that corresponds to that feature. We perform this by moving data points along the feature dimension to a baseline feature value while staying on the data manifold, as estimated by a deep generative model. Then we observe how the model's performance changes on the modified test data set, with the target feature dimension removed. We test our method on deep neural network models trained on synthetic image data with known ground truth, an Alzheimer's disease prediction task using MRI and hippocampus segmentations from the OASIS-3 dataset, and a cell nuclei classification task using the Lizard dataset.

description: To ask a question about a black hole in quantum gravity, one must restrict initial or boundary data to ensure that a black hole is actually present. For two-dimensional dilaton gravity, and probably a much wider class of theories as well, the imposition of a "stretched horizon" constraint alters the algebra of symmetries at the horizon, introducing a central term. Standard conformal field theory techniques can then then be used to obtain the asymptotic density of states, reproducing the Bekenstein-Hawking entropy. The microscopic states responsible for black hole entropy can thus be viewed as "would-be pure gauge" states that become physical because the symmetry is altered by the requirement that a horizon exist.

description: Farm planning in the non-certain world is complex so that models which adequately represent this situation are difficult and expensive to experiment with. Thus a range of linear programming models based on simplifications has been suggested for planning under non-certainty. This discussion reviews the problem of farm system infeasibility which can arise from the Lise of these models and suggests an alternative approach.

description: We discover the existence of vortex solitons supported by the surface between two optical lattices imprinted in Kerr-type nonlinear media. Such solitons can feature strongly noncanonical profiles, and we found that their properties are dictated by the location of the vortex core relative to the surface. The refractive index modulation forming the lattices at both sides of the interface results in complete stability of the vortex solitons in wide domains of their existence, thus introducing the first known example of stable topological solitons supported by a surface.

description: Metastable states of quantum many-body systems with confinement offer a means to simulate false vacuum phenomenology, including non-equilibrium dynamical processes like decay by nucleation, in truncated limits. Recent work has examined the decay process in 1D ferromagnetic Ising spins and superfluids. In this paper, we study nucleation dynamics in 1D antiferromagnetic neutral atom chains with Rydberg interactions, using both numerical simulations and analytic modeling. We apply a staggered local detuning field to generate the metastable and ground states. Our efforts focus on two dynamical regimes: decay and annealing. In the first, we corroborate the phenomenological decay rate scaling and determine the associated parameter range for the decay process; in the second, we uncover and elucidate a procedure to anneal the metastable state from the initial to the final system, with intermediate nucleation events. We further propose experimental protocols to prepare the required states and perform quenches on near-term neutral atom quantum simulators, examining the experimental feasibility of our proposed setup and parameter regime.

Effective action for vortex dynamics in clean d-wave superconductors

description: We describe the influence of the gapless, nodal, fermionic quasiparticles of a two-dimensional d-wave superconductor on the motion of vortices. A continuum, functional formalism is used to obtain the effective vortex action, after the fermions have been integrated out. At zero temperture (T), the leading terms in the vortex action retain their original form, with only a finite renormalization of the vortex effective mass from the fermions. A universal "sub-ohmic" damping of the vortex motion is also found. At T>0, we find a Bardeen-Stephen viscous drag term, with a universal co-efficient which vanishes as ~T^2. We present a simple scaling interpretation of our results, in which quantum-critical Dirac fermions respond to a moving point singularity. Our results appear to differ from those of the semiclassical theory, which obtains more singular corrections to a vortex mass appearing in transport equations.

description: Metastable states arise in a range of quantum systems and can be observed in various dynamical scenarios, including decay, bubble nucleation, and long-lived oscillations. The phenomenology of metastable states has been examined in quantum many-body systems, notably in 1D ferromagnetic Ising spin systems and superfluids. In this paper, we study long-lived oscillations of metastable and ground states in 1D antiferromagnetic neutral atom chains with long-range Rydberg interactions. We use a staggered local detuning field to achieve confinement. Using theoretical and numerical models, we identify novel spectral signatures of quasiparticle oscillations distinct to antiferromagnetic neutral atom systems and interpret them using a classical energy model of short-range meson repulsion. Finally, we evaluate the experimental accessibility of our proposed setup on current neutral-atom platforms and discuss experimental feasibility and constraints.

description: We have analytically obtained the theoretical results for the Rayleigh-Sommerfeld (R-S) scalar diffraction by apertures, such as single-slit, double-slit, grating and circular aperture, moving at relativistic speeds with the velocities perpendicular to the direction of incidence. We also have studied diffraction by a single-slit of oscillatory shutter. Our study would be significant in probing the relativistic transverse Doppler effect on the intensity pattern of the diffracted field.

Religious socialization : a test of the chanelling hypothesis of parental influence on adolescent faith maturity
Creators: name: Martin, Todd Forrest
Publisher: name: University of British Columbia
Year: 2009

description: Studies have consistently shown the family to be the most influential socializing agent in the life of the children, including the area of religious socialization. The pathways by which this occurs and the variables moderating the strength of the parental influence are still being explored but involves a variety of variables such as parenting style, parental religiosity, gender, age of the child, and the influence of peer networks. Recent research on faith transfer through the generations has shown the acquisition of religiosity has as much or more to do with what goes on in the family than what goes on in the religious institution. This study proposes to test the channeling hypothesis which looks at the indirect effect that parental religiosity has on offspring. By channeling or directing a child into secondary religious networks such as congregational influences, peer groups, education systems and potential mates, a parent indirectly affects the religiosity of a child. The use of a national survey of 11,000 adolescents and adults in six Protestant denominations produced a sub-sample of 2,365 youth that was analyzed to determine if there is support for the notion that parents do have a direct main effect on adolescent religiosity, if it is lasting, and how the intervention of congregational and peer influences impact the outcome variable, faith maturity. As expected, parental factors were significantly related to the outcome variable of faith maturity both before and after the variables of congregational and peer measure were introduced. It was found that peer influence has a small but significant mediating effect while congregational influence did not. Contrary to expectations, as the age group of the adolescent increased the relationship between peer measures and faith maturity scores did not become stronger nor did the relationship between parental scores and faith maturity become weaker. In fact, the research showed that while peer influence remained constant during the adolescent years, parental influence increased with age. Findings indicate the importance of all three socializing agents but particularly the strength of peer influence, the increasing influence of parents and the power of both parental and peer influences interacting together.

description: Using a super-operator formulation of linearized time-dependent density-functional theory, the dynamical polarizability of a system of interacting electrons is given a matrix continued-fraction representation whose coefficients can be obtained from the non-symmetric block-Lanczos method. The resulting algorithm allows for the calculation of the {\em full spectrum} of a system with a computational workload which is only a few times larger than that needed for {\em static} polarizabilities within time-independent density-functional perturbation theory. The method is demonstrated with the calculation of the spectrum of benzene, and prospects for its application to the large-scale calculation of optical spectra are discussed.

description: We report our progress in the high-temperature superconductor (HTS) Josephson junction fabrication process founded on using a focused helium ion beam damaging technique and discuss the expected device performance attainable with the HTS multi-junction device technology. Both the achievable high value of characteristic voltage $V_c=I_cR_N$ of Josephson junctions and the ability to design a large number of arbitrary located Josephson junctions allow narrowing the existing gap in design abilities for LTS and HTS circuits even with using a single YBCO film layer. A one-layer topology of active electrically small antenna is suggested and its voltage response characteristics are considered.

description: We establish a general relation between the statistics of the local Green's function for systems with chaotic wave scattering and a uniform energy loss (absorption) and its two-point correlation function for the same system without absorption. Within the random matrix approach this kind of a fluctuation dissipation relation allows us to derive the explicit analytical expression for the joint distribution function of the real and imaginary parts of the local Green function for all symmetry classes as well as at an arbitrary degree of the time-reversal symmetry breaking in the system. The outstanding problem of the orthogonal symmetry is further reduced to simple quadratures. The results can be applied, in particular, to the experimentally accessible impedance and reflection in a microwave cavity attached to a single-mode antenna.
