description: Acrylic is a common material used in dark matter and neutrino detectors for light guides, transparent vessels, and neutron shielding, creating an intermediate medium between the target volume and photodetectors. Acrylic has low absorption within the visible spectrum and has a high capture cross section for neutrons. The natural radioactivity in photodetectors is a major source of background neutrons for low background detectors making the use of acrylic attractive for shielding and background reduction. To test the optical properties of acrylic we measured the transmittance and attenuation length of fourteen samples of acrylic from four different manufacturers. Samples were evaluated at five different wavelengths between 375 nm and 632 nm. We found that all samples had excellent transmittance at wavelengths greater than 550 nm. Transmittance was found to decrease below 550 nm. As expected, UV-absorbing samples showed a sharp decrease in transmittance below 425 nm compared to UV-transmitting samples. We report attenuation lengths for the three shortest wavelengths for comparison and discuss how the acrylic was evaluated for use in the MiniCLEAN single-phase dark matter detector.

description: We find the probability density function $\mathcal{P}(V_{\texttt{r}})$ of the relativistic relative velocity for two colliding particles in a non-degenerate relativistic gas. The distribution reduces to Maxwell distribution for the relative velocity in the non-relativistic limit. We find an exact formula for the mean value $\langle V_{\texttt{r}}\rangle$. The mean velocity tends to the Maxwell's value in the non-relativistic limit and to the velocity of light in the ultra-relativistic limit. At a given temperature $T$, when at least for one of the two particles the ratio of the rest energy over the thermal energy $m c^2/k_B T$ is smaller than 40 the Maxwell distribution is inadequate.

description: O interesse da comunidade de pesquisa em Engenharia de Software (ES) pela temática sustentabilidade tem crescido consideravelmente ao longo dos últimos anos. Vários esforços têm sido dedicados a compreender como a ES pode ajudar a atingir os objetivos de sustentabilidade. Para isso, os engenheiros de software precisam concordar com os conceitos inerentes ao domínio e suas propriedades de forma que possam ter uma compreensão clara, comum e compartilhada do conhecimento. Porém, evidências obtidas da literatura recente em ES sustentável mostram que ainda há confusão e incompreensão em relação aos conceitos e termos utilizados. A falta de clareza pode resultar na fraca adoção da sustentabilidade no ciclo de vida de desenvolvimento do software. Diante de tal questão, esta pesquisa tem como objetivo propor a OntoGreen, uma ontologia de domínio para conceituar os termos aplicados no novo contexto. Para alcançar esse objetivo, o método de pesquisa aplicado possui um caráter exploratório sobre o estado da arte em ES Sustentável e uma abordagem qualitativa para avaliação da Ontologia proposta. A principal contribuição deste trabalho será a ontologia que proverá a formalização semântica dos conceitos relativos ao domínio ES Sustentável a partir de definições extraídas da literatura pesquisada. Por fim, espera-se que a solução proposta possa ser compartilhada e expandida por pesquisadores e engenheiros de software reduzindo, assim, a lacuna conceitual sobre ES sustentável e promovendo o entendimento comum do domínio.

description: The aim of the present paper is to introduce a generalized quantum cluster character, which assigns to each object V of a finitary Abelian category C over a finite field FF_q and any sequence ii of simple objects in C the element X_{V,ii} of the corresponding algebra P_{C,ii} of q-polynomials. We prove that if C was hereditary, then the assignments V-> X_{V,ii} define algebra homomorphisms from the (dual) Hall-Ringel algebra of C to the P_{C,ii}, which generalize the well-known Feigin homomorphisms from the upper half of a quantum group to q-polynomial algebras. If C is the representation category of an acyclic valued quiver (Q,d) and ii=(ii_0,ii_0), where ii_0 is a repetition-free source-adapted sequence, then we prove that the ii-character X_{V,ii} equals the quantum cluster character X_V introduced earlier by the second author in [29] and [30]. Using this identification, we deduce a quantum cluster structure on the quantum unipotent cell corresponding to the square of a Coxeter element. As a corollary, we prove a conjecture from the joint paper [5] of the first author with A. Zelevinsky for such quantum unipotent cells. As a byproduct, we construct the quantum twist and prove that it preserves the triangular basis introduced by A. Zelevinsky and the first author in [6].

Asymptotic relations for weighted finite multiple zeta values

subject: 11M32, 11A07

description: Multiple zeta values are real numbers defined by an infinite series generalizing values of the Riemann zeta function at positive integers. Finite truncations of this series are called multiple harmonic sums and are known to have interesting arithmetic properties. When the truncation point is one less than a prime $p$, the mod $p$ values of multiple harmonic sums are called finite multiple zeta values. The present work introduces a new class of congruence for multiple harmonic sums, which we call weighted congruences. These congruences can hold modulo arbitrarily large powers of $p$. Unlike results for finite multiple zeta values, weighted congruences typically involve harmonic sums of multiple weights, which are multiplied by explicit powers of $p$ depending on weight. We also introduce certain formal weighted congruences inolving an infinite number of terms, which we call asymptotic relations. We define a weighted analogue of the finite multiple zeta function, and give an algebraic framework for classifying weighted congruences and asymptotic relations.

Estimativa de incerteza baseada em aprendizado profundo para classificação de múltiplas lesões glomerulares e detecção de amostras fora da distribuição

description: Glomérulos são estruturas histológicas localizadas no início dos néfrons nos rins, tendo importância primordial no diagnóstico de diversas doenças renais. Visto que classificar lesões glomerulares é uma tarefa demorada que requer patologistas experientes, métodos de classificação automática podem apoiar os especialistas em cenários de diagnóstico e tomada de decisão. Recentemente, o estado-da-arte em classificação de imagens médicas, em sua maioria, se baseou em abordagens de aprendizado profundo (deep learning), que são métodos propensos a retornarem predições excessivamente confiantes, mesmo para amostras fora da distribuição (out-of-distribution, OOD) do domínio de treinamento. Determinar se as entradas são amostras OOD é essencial para garantir a segurança e a robustez de aplicações críticas em aprendizado de máquina. Nesse contexto, propomos uma estrutura unificada composta por estimativa de incerteza e classificação glomerular de múltiplas lesões. O modelo proposto classifica a entrada em dados "in-" ou OOD: Se a amostra for uma imagem OOD, a entrada é desconsiderada, indicando que o modelo "não sabe" a classe a ser predita; caso contrário, se a amostra for classificada como dentro da distribuição esperada, o modelo prediz uma dada classe de modo que a predição pode ser avaliada com uma proposta de representação de incerteza baseada em thresholds para apontar se a predição é confiável ou se a amostra precisa ser reavaliada com maior atenção pelo especialista.

description: In this paper we clarify the relation between the invariant relativistic relative velocity $V_\text{r}$, the Møller velocity $\bar{v}$, and the non-relativistic relative velocity $v_r$. Adopting $V_{\text{r}}$ as the true physical relative velocity for pair-collisions in a non-degenerate relativistic gas, we show that in the frame co-moving with the gas (i) the thermally averaged cross section times relative velocity $$ that appears in the density evolution equation for thermal relics is reformulated only in terms of $V_\text{r}$ and $\mathcal{P}(V_{\text{r}})$ in a manifestly Lorentz invariant form; (ii) the frame-dependent issues of the standard formulation in terms of the Møller velocity, as well as "superluminal" relative velocities, are not present in this formulation. Furthermore, considering the annihilation of dark matter into a particle-antiparticle pair $f\bar{f}$, in the cases $m_f=0$, $m_f=m$ and $m_f \gg m$, we find that the coefficients of the low velocity expansion of $$ admit an exact analytical representation in terms of the Meijer $G$ functions that can be reduced to combinations of modified Bessel functions of the second kind.

description: We demonstrate the existence of generalized synchronization in systems that act as mediators between two dynamical units that, in turn, show complete synchronization with each other. These are the so-called relay systems. Specifically, we analyze the Lyapunov spectrum of the full system to elucidate when complete and generalized synchronization appear. We show that once a critical coupling strength is achieved, complete synchronization emerges between the systems to be synchronized, and at the same point, generalized synchronization with the relay system also arises. Next, we use two nonlinear measures based on the distance between phase-space neighbors to quantify the generalized synchronization in discretized time series. Finally, we experimentally show the robustness of the phenomenon and of the theoretical tools here proposed to characterize it.

Cosmic ray propagation in galactic turbulence

description: We revisit propagation of galactic cosmic rays (CRs) in light of recent advances in CR diffusion theory in realistic interstellar turbulence. We use a tested model of turbulence in which it has been shown that fast modes dominate scattering of CRs. As a result, propagation becomes inhomogeneous and environment dependent. By adopting the formalism of the nonlinear theory developed by Yan & Lazarian, we calculate the diffusion of CRs self-consistently from first principles. We assume a two- phase model for the Galaxy to account for different damping mechanisms of the fast modes, and we find that the energy dependence of the diffusion coefficient is mainly affected by medium properties. We show that it gives a correct framework to interpret some of the recent CR puzzles.

description: We establish that over a C^{2,1} manifold the exponential map of any Lipschitz connection or spray determines a local Lipeomophism and that, furthermore, reversible convex normal neighborhoods do exist. To that end we use the method of Picard-Lindelof approximation to prove the strong differentiability of the exponential map at the origin and hence a version of Gauss' Lemma which does not require the differentiability of the exponential map. Contrary to naive differential degree counting, the distance functions are shown to gain one degree and hence to be C^{1,1}. As an application to mathematical relativity, it is argued that the mentioned differentiability conditions can be considered the optimal ones to preserve most results of causality theory. This theory is also shown to be generalizable to the Finsler spacetime case. In particular, we prove that the local Lorentzian(-Finsler) length maximization property of causal geodesics in the class of absolutely continuous causal curves holds already for C^{1,1} spacetime metrics. Finally, we study the local existence of convex functions and show that arbitrarily small globally hyperbolic convex normal neighborhoods do exist.

description: We present the new version of the Mathematica package SARAH which provides the same features for a non-supersymmetric model as previous versions for supersymmetric models. This includes an easy and straightforward definition of the model, the calculation of all vertices, mass matrices, tadpole equations, and self-energies. Also the two-loop renormalization group equations for a general gauge theory are now included and have been validated with the independent Python code PyR@te. Model files for FeynArts, CalcHep/CompHep, WHIZARD and in the UFO format can be written, and source code for SPheno for the calculation of the mass spectrum, a set of precision observables, and the decay widths and branching ratios of all states can be generated. Furthermore, the new version includes routines to output model files for Vevacious for both, supersymmetric and non-supersymmetric, models. Global symmetries are also supported with this version and by linking Susyno the handling of Lie groups has been improved and extended.

description: A doença falciforme caracteriza-se por uma alteração genética hereditária na hemoglobina, onde as hemácias responsáveis pelo transporte de oxigênio para as células assumem um formato de foice em condições de desoxigenação. Essa patologia cursa com diversas manifestações clínicas, sendo um desafio complexo, do ponto de vista clínico, predizer qual fenótipo um paciente é mais propenso a desenvolver. Apesar do exame clínico apontar para uma possível doença hematológica, o padrão ouro para determinar se um paciente é portador da doença falciforme é a eletroforese da hemoglobina, que é dificultada em regiões com pouca infraestrutura hospitalar. As características mais comuns apresentadas nos portadores da doença estão relacionadas aos quadros de dor, insuficiência pulmonar, doença renal, acidente vascular cerebral e insuficiência cardíaca. Nesse contexto, este trabalho propõe o emprego de técnicas de aprendizagem de máquina sobre dados laboratoriais e clínico-epidemiológicos, obtidos nos prontuários médicos para sugerir uma maior predisposição de um paciente a um determinado fenótipo, tendo como resultado esperado o auxílio ao médico na tomada de decisão no seguimento e manejo clínico desses indivíduos.

description: In Stochastic blockmodels, which are among the most prominent statistical models for cluster analysis of complex networks, clusters are defined as groups of nodes with statistically similar link probabilities within and between groups. A recent extension by Karrer and Newman incorporates a node degree correction to model degree heterogeneity within each group. Although this demonstrably leads to better performance on several networks it is not obvious whether modelling node degree is always appropriate or necessary. We formulate the degree corrected stochastic blockmodel as a non-parametric Bayesian model, incorporating a parameter to control the amount of degree correction which can then be inferred from data. Additionally, our formulation yields principled ways of inferring the number of groups as well as predicting missing links in the network which can be used to quantify the model's predictive performance. On synthetic data we demonstrate that including the degree correction yields better performance both on recovering the true group structure and predicting missing links when degree heterogeneity is present, whereas performance is on par for data with no degree heterogeneity within clusters. On seven real networks (with no ground truth group structure available) we show that predictive performance is about equal whether or not degree correction is included; however, for some networks significantly fewer clusters are discovered when correcting for degree indicating that the data can be more compactly explained by clusters of heterogenous degree nodes.

description: The propagation of cosmic rays (CRs) in turbulent interstellar magnetic fields is typically described as a spatial diffusion process. This formalism predicts only a small deviation from an isotropic CR distribution in the form of a dipole in the direction of the CR density gradient or relative background flow. We show that the existence of a global CR dipole moment necessarily generates a spectrum of higher multipole moments in the local CR distribution. These "anomalous" anisotropies are a direct consequence of Liouville's theorem in the presence of a local turbulent magnetic field. We show that the predictions of this model are in excellent agreement with the observed power spectrum of multi-TeV CRs.

This extends a result of Adams and Reid, who showed that in the case that M is not hyperbolic, there is a universal bound of 7.35534... . As part of the proof, we establish a bound for the systole length of a non-compact finite volume hyperbolic manifold which grows asymptotically like (4/3)log(V).

Optimal values of bipartite entanglement in a tripartite system

Publisher: name: arXiv
Year: 2013
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: For a general tripartite system in some pure state, an observer possessing any two parts will see them in a mixed state. By the consequence of Hughston-Jozsa-Wootters theorem, each basis set of local measurement on the third part will correspond to a particular decomposition of the bipartite mixed state into a weighted sum of pure states. It is possible to associate an average bipartite entanglement ($\bar{\mathcal{S}}$) with each of these decompositions. The maximum value of $\bar{\mathcal{S}}$ is called the entanglement of assistance ($E_A$) while the minimum value is called the entanglement of formation ($E_F$). An appropriate choice of the basis set of local measurement will correspond to an optimal value of $\bar{\mathcal{S}}$; we find here a generic optimality condition for the choice of the basis set. In the present context, we analyze the tripartite states $W$ and $GHZ$ and show how they are fundamentally different.

description: Digital tools are useful and in many cases essential for Citizen Science projects. Digital tools, such as mobile applications, desktop GIS (e.g. QGIS), interactive notebooks (e.g. Jupyter Notebooks), and visual data analysis applications (e.g. Orange) help to collect and analyse geospatial data. Similar to scientific research, Citizen Science is also moving to the Cloud. Online computing platforms that provide analysis-ready data and interactive and collaborative analysis environment at low cost are becoming more and more important for Citizen Science activities. However, the threshold to start using them is currently high and any serious attempt to support such activities requires a well-designed approach with training targeting citizen scientists. This is especially the case for primary and secondary school students, whose curricula pay special attention on digital technology and promote involvement to Citizen Science activities. Our project focuses on this group and aims to find out how pre-university students and teachers can be supported to use a modern digital geoscience toolbox for Citizen Science projects. In cooperation with University of Twente Pre‑U, a feasibility study will be performed to identify how the platform and available tools can be used for Citizen Science activities. Potential use cases and expected impacts will be documented. Finally, a roadmap for developing well-written training material for the target audience will be prepared in consultation with teachers. First workshop with the teachers was organized during the 15th NLT Conference in February 2023, during which some of the available tools were introduced and feedback from the teachers was collected.

Low completion rates are even greater when looking at Black and Latina women in computer science (CS). This phenomenological study examined how the academic and social experiences of nine Black and Latina women computer science students shaped their journeys and sense of belonging as developing computer scientists. This study drew upon two interviews and journal entries to unpack how this group of women of color is experiencing their journeys through CS at Rutgers. I used Critical Race Theory (CRT) and Strayhorn’s (2012, 2018) model for sense of belonging for STEM students as frameworks for interpreting the experiences of women of color and what may lead to attrition or unwelcome environments. The findings of this study depict an isolating experience for Black and Latina students in CS. These students faced racist and sexist comments from their peers, which deeply impacted their ability to feel connected. They were conscious of their status as the “only one,” which hindered their ability to develop a sense of belonging. To counteract these feelings, many of the participants found solace in women-centric programming, including a Computer Science Living-Learning Community. Some critical recommendations include funding women-centric intervention programs, implementing inclusive hiring practices to hire more women in CS leadership positions, and building a working group of faculty and staff to examine the issues in the local context. The paper begins with the statement of the problem and social context. Next, I review relevant literature that examines the lack of women of color in STEM and CS. Following the literature review, I describe the methods and findings. Finally, I conclude with implications and limitations.

description: We derive the ultimate bounds on the performance of nonlinear measurement schemes in the presence of noise. In particular, we investigate the precision of the second-order estimation scheme in the presence of the two most detrimental types of noise, photon loss and phase diffusion. We find that the second-order estimation scheme is affected by both types of noise in an analogous way as the linear one. Moreover, we observe that for both types of noise the gain in the phase sensitivity with respect to the linear estimation scheme is given by a multiplicative term $\mathcal{O}(1/N)$. Interestingly, we also find that under certain circumstances, a careful engineering of the environment can, in principle, improve the performance of measurement schemes affected by phase diffusion.

description: Asynchronous replication of the genome has been associated with different rates of point mutation and copy number variation (CNV) in human populations. Here, we explored if the bias in the generation of CNV that is associated to DNA replication timing might have conditioned the birth of new protein-coding genes during evolution. We show that genes that were duplicated during primate evolution are more commonly found among the human genes located in late-replicating CNV regions. We traced the relationship between replication timing and the evolutionary age of duplicated genes. Strikingly, we found that there is a significant enrichment of evolutionary younger duplicates in late replicating regions of the human and mouse genome. Indeed, the presence of duplicates in late replicating regions gradually decreases as the evolutionary time since duplication extends. Our results suggest that the accumulation of recent duplications in late replicating CNV regions is an active process influencing genome evolution.

description: We present a new catalog of 404 M giant candidates found in the UKIRT Infrared Deep Sky Survey (UKIDSS). The 2,400 deg$^2$ available in the UKIDSS Large Area Survey Data Release 8 resolve M giants through a volume four times larger than that of the entire Two Micron All Sky Survey. Combining near-infrared photometry with optical photometry and proper motions from the Sloan Digital Sky Survey yields an M giant candidate catalog with less M dwarf and quasar contamination than previous searches for similarly distant M giants. Extensive follow-up spectroscopy of this sample will yield the first map of our Galaxy's outermost reaches over a large area of sky. Our initial spectroscopic follow-up of $\sim$ 30 bright candidates yielded the positive identification of five M giants at distances $\sim 20-90$ kpc. Each of these confirmed M giants have positions and velocities consistent with the Sagittarius stream. The fainter M giant candidates in our sample have estimated photometric distances $\sim 200$ kpc (assuming $[Fe/H]$ = 0.0), but require further spectroscopic verification. The photometric distance estimates extend beyond the Milky Way's virial radius, and increase by $\sim 50\%$ for each 0.5 dex decrease in assumed $[Fe/H]$. Given the number of M giant candidates, initial selection efficiency, and volume surveyed, we loosely estimate that at least one additional Sagittarius-like accretion event could have contributed to the hierarchical build-up of the Milky Way's outer halo.

Dissimulodorylus

description: Genus Dissimulodorylus Sosiak, Borowiec, & Barden gen. nov. Diagnosis: Worker. Dissimulodorylus can be distinguished from most doryline genera by the combination of lack of eyes, complete pronotomesopleural suture, propodeal spiracle positioned high on the propodeum and single waist segment. These characteristics make it most like Dorylus, which can be differentiated by the presence of an impressed pygidial field and lack of fused, dorsoventrally flat, overhanging and triangularly shaped frontal lobes characteristic for this fossil. Type species: Dissimulodorylus perseus sp. nov. Etymology: From Latin ‘dissimulo’ meaning to conceal, hide or disregard, in reference to the type specimen eluding description for likely 80 years.

Polaron dynamics and decoherence in an interacting two-spin system coupled to optical phonon environment

description: We study two anisotropically interacting spins coupled to optical phonons; we restrict our analysis to the regime of strong coupling to the environment, to the antiadiabatic region, and to the subspace with zero value for $S^z_T$ (the z-component of the total spin). In the case where each spin is coupled to a different phonon bath, we assume that the system and the environment are initially uncorrelated (and form a simply separable state) in the polaronic frame of reference. By analyzing the {polaron} dynamics through non-Markovian quantum master equation, we find that the system manifests a small amount of decoherence that decreases both with increasing non-adiabaticity and with enhancing strength of coupling; whereas, under the Markovian approximation, the polaronic system exhibits a decoherence free behavior. For the situation where both spins are coupled to the same phonon bath, we also show that the system is decoherence free in the subspace where $S^z_T$ is fixed. To suppress decoherence through quantum control, we employ a train of pi pulses and demonstrate that unitary evolution of the system can be retained. We propose realization of a weakly decohering charge qubit from an electron in an oxide-based (tunnel-coupled) double quantum dot system.

description: The mass and current coupling constant of the $D_{s2}^* (2573)$ charmed-strange meson is calculated in the framework of two-point QCD sum rule approach. Although the quantum numbers of this meson is not exactly known, its width and decay modes are consistent with $I(J^P)=0(2^+)$, which we consider to write the interpolating current used in our calculations. Replacing the light strange quark with up or down quark we also compare the results with those of $D_{2}^*$ charmed tensor meson and estimate the order of SU(3) flavor symmetry violation.
