description: We explain the $e^+ e^-$ excess observed by the DAMPE Collaboration using a dark matter model based upon the Higgs triplet model and an additional hidden $SU(2)_X$ gauge symmetry. Two of the $SU(2)_X$ gauge bosons are stable due to a residual discrete symmetry and serve as the dark matter candidate. We search the parameter space for regions that can explain the observed relic abundance, and compute the flux of $e^+ e^-$ coming from a nearby dark matter subhalo. With the inclusion of background cosmic rays, we show that the model can render a good fit to the entire energy spectrum covering the AMS-02, Fermi-LAT and DAMPE data.

An ‘Innocent’ Desire: Food in Günter Grass’s The Tin Drum

translation
ersatz joy
temptation

description: In the original English translation of Günter Grass’ The Tin Drum, the “Schwarze Köchin” was translated as “witch, black as pitch.” Breon Mitchell’s new 2009 translation reinstates the “Black Cook” to her rightful place as the inescapable terror that haunts Oskar Matzerath throughout his life. For English-language readers, her reappearance helps to emphasize the importance of food in Grass’ novel. This essay explores food’s multifaceted role in The Tin Drum; it is by turns a comforter, a tempter, and a murderer. Ultimately, however, it stands as a warning to the reader, as food’s presumed innocence, its everyday banality, belies its potential to destroy.

description: El texto ofrece un análisis del personaje K. de la novela El castillo de Kafka, considerado como arquetipo de la condición del migrante. Leyendo dicho texto en paralelo con el pensamiento de Arendt, se busca ofrecer unos elementos de análisis útiles para las ciencias políticas y el derecho en relación con el problema de la migración, con especial referencia a Colombia e Italia. Finalmente, se plantean unas reflexiones críticas acerca de la categoría jurídico-política de “migrante económico” y sobre la manera en que su uso contribuye a banalizar un problema mucho más complejo y enmascara una realidad de violación sistemática de derechos humanos de población vulnerable que se relaciona, de forma indisoluble, con la trata de personas. Para este ejercicio se consideran conceptos fundamentales del derecho privado como identidad, nacionalidad, sujeto de derecho y autonomía.
description: The text offers an analysis of the character K. from Kafka’s novel The castle, considered as an archetype of the migrant’s condition. Reading this text in parallel with Arendt’s thought, it seeks to offer useful analysis elements to the political science and the law regarding the problem of migration, especially in Colombia and Italy. Finally, it presents some critical reflections about the legal-political category of “economic migrant”. This category contributes to trivialize a much more complex problem and mask a reality of systematic violation of human rights of vulnerable population related with human trafficking. For this exercise, fundamental concepts of private law such as identity, nationality, subject of law and autonomy are considered.

description: Meyer and Kadane (1992) report a method for reconstructing the adjusted population (by age, race, and sex) for the half of the census blocks in Florida not made available to them. This article studies the full adjusted data set, which is now available, to examine how well the original reconstruction was done. This is a rare opportunity to learn the exact value of quantities estimated. The results show that the largest difference between the Meyer and Kadane (1992) approximation and the adjusted counts at the Congressional district level was 79 persons for one district. Thus, the approximation could have been used instead of the unavailable adjusted census, had the redistricting decision-makers so chosen.

description: Convergence of mcr and carbapenemase genes has been sporadically detected in Enterobacter cloacae complex (ECC) with an upward trend. However, the state of the epidemic and underlying mechanism of such convergence has been poorly understood. In this study, the co-occurrence of MCR and carbapenemases was systematically analyzed in 230 clinical ECC isolates collected between 2000 and 2018 together with a global dataset consisting of 3,559 ECC genomes compiled from GenBank. We identified 48 mcr-9/mcr-10-positive isolates (MCR-ECC) (20.9%) in our collection, and a comparable ratio of MCR-ECC (720/3559, 20.2%) was detected in the global dataset. A high prevalence of carbapenemase-producing MCR-ECC (MCR-CREC) was further identified in the MCR-ECC of both datasets (16/48, 33.3%; 388/720, 53.9%), demonstrating a frequent convergence of mcr-9/10 and carbapenemase genes in ECC worldwide. An epidemic IncHI2/2A plasmid with a highly conserved backbone was identified and largely contributed to the dissemination of mcr-9 in ECC worldwide. A highly conserved IncX3-type NDM-1-carrying plasmid and IncN-type IMP-4-carrying plasmid were additionally detected in MCR-CREC isolated in China. Our surveillance data showed that MCR-CREC emerged (in 2013) much later than MCR-ECC (in 2000), indicating that MCR-CREC could be derived from MCR-ECC by additional captures of carbapenemase-encoding plasmids. Tests of plasmid stability and incompatibility showed that the mcr-9/mcr-10-encoding plasmids with the NDM-1-encoding plasmids stably remained in ECC but incompatible in Escherichia coli, suggesting that the convergence was host-dependent. The findings extend our concern on the convergence of resistance to the last resort antibiotics and highlight the necessity of continued surveillance in the future.
Evaluating Polygraph Data

description: The objective of automated scoring algorithms for polygraph data is to create reliable and statistically valid classification schemes minimizing both false positive and false negative rates. With increasing computing power and well developed statistical methods for modeling and classification we often launch analyses without much consideration for the quality of the datasets and the underlying assumptions of the data collection. In this paper we try to assess the validity of logistic regression when faced with a highly variable but small dataset. We evaluate 149 real-life specific incident polygraph cases and review current automated scoring algorithms. The data exhibit enormous variability in the subject of investigation, format, structure, and administration making them hard to standardize within an individual and across individuals. This makes it difficult to develop generalizable statistical procedures. We outline steps and detailed decisions required for the conversion of continuous polygraph readings into a set of features. With a relativelly simple approach we obtain accuracy rates comparable to those currently reported by other algorithms and manual scoring. Complexity that underlines assessment and classification of examinee's deceptiveness is evident in a number of models that account for different predictors yet give similar results, typically ``overfitting" with the increasing number of features. While computerized systems have the potential to reduce examineer variability and bias, the evidence that they have achieved this potential is meager at best.

description: We present results of 2D axisymmetric core-collapse supernova simulations, employing the FORNAX code, of nine progenitor models spanning 12 to 25 M$_{\odot}$ and evolved over a 20,000-km grid. We find that four of the nine models explode with inelastic scattering off electrons and neutrons as well as the many-body correction to neutrino-nucleon scattering opacities. We show that these four models feature sharp Si-O interfaces in their density profiles, and that the corresponding dip in density reduces the accretion rate around the stalled shock and prompts explosion. The non-exploding models lack such a steep feature, suggesting that Si-O interface is one key to explosion. Furthermore, we show that all of the non-exploding models can be nudged to explosion with modest changes to macrophysical inputs, including moderate rotation and perturbations to infall velocities, as well as to microphysical inputs, including changes to neutrino-nucleon interaction rates, suggesting that all the models are perhaps close to criticality. Exploding models have energies of few $\times$10$^{50}$ ergs at the end of our simulation, and are rising, suggesting the need to continue these simulations over larger grids and for longer times to reproduce the energies seen in Nature. We find that the morphology of the explosion contributes to the explosion energy, with more isotropic ejecta producing larger explosion energies. However, we do not find evidence for the Lepton-number Emission Self-Sustained Asymmetry. Finally, we look at PNS properties and explore the role of dimension in our simulations. We find that convection in the proto-neutron star (PNS) produces larger PNS radii as well as greater "$ν_μ$" luminosities in 2D compared to 1D.

description: En este estudio, se investigaron las estrategias de afrontamiento familiar utilizadas por familias con jóvenes universitarios en la etapa de adultez emergente durante la pandemia de COVID-19, y su correlación con el funcionamiento familiar. Se emplearon dos herramientas de medición, el FACES III para evaluar el funcionamiento familiar y el F-COPES para analizar las estrategias de afrontamiento en situaciones de crisis. Tras un análisis de quince familias, se encontró que las estrategias de afrontamiento adquieren significado dentro de los contextos particulares de cada familia, sin establecer una relación directa con el funcionamiento familiar. Cada familia utilizó estas estrategias de acuerdo a sus sistemas de creencias, redes de apoyo, niveles de comunicación y formas de resolver conflictos. Se destaca la importancia de las estrategias de afrontamiento externo, que permitieron movilizar recursos a nivel individual, familiar y social para enfrentar las situaciones de estrés.
description: In this study, we investigated the coping strategies used by families with young university students in the stage of emerging adulthood during the COVID-19 pandemic, and their correlation with family functioning. Two measurement tools were employed, the FACES III to assess family functioning, and the F-COPES to analyze coping strategies in crisis situations. After analyzing fifteen families, it was found that coping strategies acquire meaning within the specific contexts of each family, without establishing a direct relationship with family functioning. Each family utilized these strategies based on their belief systems, support networks, levels of communication, and methods of conflict resolution. The significance of external coping strategies is highlighted, as they facilitated the mobilization of resources at the individual, family, and social levels to cope with stressful situations.

description: We investigate the ground state properties of a lattice trapped bosonic system coupled to a Lieb-Liniger type gas. Our main goal is the description and in depth exploration and analysis of the two-species many-body quantum system including all relevant correlations beyond the standard mean-field approach. To achieve this, we use the Multi-Configuration Time-Dependent Hartree method for Mixtures (ML-MCTDHX). Increasing the lattice depth and the interspecies interaction strength, the wave function undergoes a transition from an uncorrelated to a highly correlated state, which manifests itself in the localization of the lattice atoms in the latter regime. For small interspecies couplings, we identify the process responsible for this cross-over in a single-particle-like picture. Moreover, we give a full characterization of the wave function's structure in both regimes, using Bloch and Wannier states of the lowest band, and we find an order parameter, which can be exploited as a corresponding experimental signature. To deepen the understanding, we use an effective Hamiltonian approach, which introduces an induced interaction and is valid for small interspecies interaction. We finally compare the ansatz of the effective Hamiltonian with the results of the ML-MCTDHX simulations.

description: We present the design, fabrication and measured performance of a hierarchical sinuous-antenna phased array coupled to superconducting transition-edge-sensor (TES) bolometers for millimeter wavelengths. The architecture allows for dual-polarization wideband sensitivity with a beam width that is approximately frequency-independent. We report on measurements of a prototype device, which uses three levels of triangular phased arrays to synthesize beams that are approximately constant in width across three frequency bands covering a 3:1 bandwidth. The array element is a lens-coupled sinuous antenna. The device consists of an array of hemispherical lenses coupled to a lithographed wafer, which integrates TESs, planar sinuous antennas and microwave circuitry including band-defining filters. The approximately frequency-independent beam widths improve coupling to telescope optics and keep the the sensitivity of an experiment close to optimal across a broad frequency range. The design can be straightforwardly modified for use with non-TES lithographed cryogenic detectors such as kinetic inductance detectors (KIDs). Additionally, we report on the design and measurements of a broadband 180-degree hybrid that can simplify the design of future multichroic focal planes including but not limited to hierarchical phased arrays.

description: We constrain the dark energy equation of state parameter, $w$, using the power spectrum of the thermal Sunyaev-Zeldovich (tSZ) effect. We improve upon previous analyses by taking into account the trispectrum in the covariance matrix and marginalising over the foreground parameters, the correlated noise, the mass bias $B$ in the Planck universal pressure profile, and all the relevant cosmological parameters (i.e., not just $Ω_{\mathrm{m}}$ and $σ_8$). We find that the amplitude of the tSZ power spectrum at $\ell\lesssim 10^3$ depends primarily on $F\equiv σ_{8}(Ω_{\mathrm{m}}/B)^{0.40}h^{-0.21}$, where $B$ is related to more commonly used variable $b$ by $B=(1-b)^{-1}$. We measure this parameter with 2.6\% precision, $F=0.460\pm 0.012$ (68% CL). By fixing the bias to $B=1.25$ and adding the local determination of the Hubble constant $H_0$ and the amplitude of the primordial power spectrum constrained by the Planck Cosmic Microwave Background (CMB) data, we find $w=-1.10\pm0.12$, $σ_{\mathrm{8}}=0.802\pm0.037$, and $Ω_{\mathrm{m}}=0.265\pm0.022$ (68% CL). Our limit on $w$ is consistent with and is as tight as that from the distance-alone constraint from the CMB and $H_0$. Finally, by combining the tSZ power spectrum and the CMB data we find, in the $Λ$ Cold Dark Matter (CDM) model, the mass bias of $B=1.71\pm 0.17$, i.e., $1-b=0.58\pm 0.06$ (68% CL).

description: Reviews of treatment completion suggest using psychological variables and more complex designs to help predict completion status and understand the relationships among variables. 102 patients (mean age 37.9 yrs) with serious emotional, coping, and interpersonal problems were admitted to a partial hospitalization program. 58 completed the program and 44 terminated prematurely. Psychological mindedness (PM), interpersonal problems, and chronicity of psychiatric problems were used as predictors. A hierarchical logistic regression was conducted. PM and chronicity emerged as statistically significant individual predictors of completion status. Only chronicity increased the odds of classifying completers, while noncompleters were not classified above chance. The interaction between PM and chronicity was statistically significant, but did not increase accurate classification over and above chronicity alone. Completers with more chronic problems had higher levels of PM. PM may act as a buffer against the negative impact of chronicity. It was found that those who completed treatment tended to benefit from treatment.

description: Nonlinear effects in pulse propagation through a medium consisting of four-level double-$Λ$-type systems are studied theoretically. We apply three continous-wave driving fields and a pulsed probe field such that they form a closed interaction loop. Due to the closed loop and the finite frequency width of the probe pulses the multiphoton resonance condition cannot be fulfilled, such that a time-dependent analysis is required. By identifying the different underlying physical processes we determine the parts of the solution relevant to calculate the linear and nonlinear response of the system. We find that the system can exhibit a strong intensity dependent refractive index with small absorption over a range of several natural linewidths. For a realistic example we include Doppler and pressure broadening and calculate the nonlinear selfphase modulation in a gas cell with Sodium vapor and Argon buffer gas. We find that a selfphase modulation of $π$ is achieved after a propagation of few centimeters through the medium while the absorption in the corresponding spectral range is small.

description: Available proofs of result of the type 'at least one of the odd zeta values $ζ(5),ζ(7),\dots,ζ(s)$ is irrational' make use of the saddle-point method or of linear independence criteria, or both. These two remarkable techniques are however counted as highly non-elementary, therefore leaving the partial irrationality result inaccessible to general mathematics audience in all its glory. Here we modify the original construction of linear forms in odd zeta values to produce, for the first time, an elementary proof of such a result - a proof whose technical ingredients are limited to the prime number theorem and Stirling's approximation formula for the factorial.

description: The penalized quasi-likelihood (PQL) approach is the most common estimation procedure for the generalized linear mixed effects model (GLMM). However, it has been noticed that the PQL tends to underestimate the variance components as well as the regression coefficients in the previous literature. In this paper, we numerically show that the bias in variance components is systematically related to the bias in the regression coefficient estimates, and also show that the bias in the variance components estimates of the PQL increase as the random effects becomes more heterogeneous.

description: We derive the universal relations for an ultracold two-component Fermi gas with spin-orbit coupling (SOC) $\sum_{α,β=x,y,z}λ_{αβ}σ_αp_β$, where $p_{x,y,z}$ and $σ_{x,y,z}$ are the single-atom momentum and Pauli operators for pseudo spin, respectively, and the SOC intensity $λ_{αβ}$ could take arbitrary value. We consider the system with an s-wave short-range interspecies interaction, and ignore the SOC-induced modification for the value of the scattering length. Using the first-quantized approach developed by S. Tan (Phys. Rev. Lett. \textbf{107}, 145302 (2011)), we obtain the short-range and high-momentum expansions for the one-body real-space correlation function and momentum distribution function, respectively. For our system these functions are $2\times2$ matrix in the pseudo-spin basis. We find that the leading-order ($1/k^{4}$) behavior of the diagonal elements of the momentum distribution function (i.e., $n_{\uparrow\uparrow}({\bf k})$ and $n_{\downarrow\downarrow}({\bf k})$) are not modified by the SOC. However, the SOC can significantly modify the behavior of the \textit{non-diagonal elements} of the momentum distribution function, i.e., $n_{\uparrow\downarrow}({\bf k})$ and $n_{\downarrow\uparrow}({\bf k})$, in the large-$k$ limit. In the absence of the SOC, the leading order of these elements is ${\cal O}(1/k^{6})$. When SOC appears, it can induce a term on the order of $1/k^{5}$. We further derive the adiabatic relation and the energy functional. Our results show the SOC can induce a new term in the energy functional, which simply describe the contribution from the SOC to the total energy. The form of the adiabatic relation for our system is not modified by the SOC.

description: Recently, there have been health and environmental concerns placed on mercury (Hg) and mercury containing compounds. This is because mercury can be toxic even at very low levels, and can accumulate in living organisms. Nonetheless, mercury has widespread uses and is often a component of many things, including dental fillings. A literature review was conducted to answer the following research question: Does mercury exposure from dental amalgam-fillings produce visibly toxic effects on the body? Two databases, SCOPUS and PubMed were used to identify and obtain all related articles published within the last fifteen years. Thirty-one relevant pieces of literature were found within the global context. The literature review focused on the general population rather than a specific age group. Studies that qualified for the literature review include those that contained the relevant information in English about: the effects of mercury on the body as a result of amalgam-filling surfaces; mercury concentrations in individuals with amalgam-fillings; amalgam-filling risk assessments; and mercury concentration thresholds prior to causing adverse effects. The study focused on toxicity levels of mercury exposure caused by dental amalgam-filling in the general population to infer if there were potential health risks. We limited our literature review to journals, articles, and reviews that were easily accessible and free. Overall, studies indicated a definitive increase in mercury levels in individuals with amalgam fillings, but there was no direct link made to adverse health outcomes.

description: Magnetoencephalography (MEG) has a high temporal resolution well-suited for studying perceptual learning. However, to identify where learning happens in the brain, one needs to ap- ply source localization techniques to project MEG sensor data into brain space. Previous source localization methods, such as the short-time Fourier transform (STFT) method by Gramfort et al.([Gramfort et al., 2013]) produced intriguing results, but they were not designed to incor- porate trial-by-trial learning effects. Here we modify the approach in [Gramfort et al., 2013] to produce an STFT-based source localization method (STFT-R) that includes an additional regression of the STFT components on covariates such as the behavioral learning curve. We also exploit a hierarchical L 21 penalty to induce structured sparsity of STFT components and to emphasize signals from regions of interest (ROIs) that are selected according to prior knowl- edge. In reconstructing the ROI source signals from simulated data, STFT-R achieved smaller errors than a two-step method using the popular minimum-norm estimate (MNE), and in a real-world human learning experiment, STFT-R yielded more interpretable results about what time-frequency components of the ROI signals were correlated with learning.

description: Pairs of active neurons frequently fire action potentials or "spikes" nearly synchronously (i.e., within 5 ms of each other). This spike synchrony may occur by chance, based solely on the neurons' fluctuating firing patterns, or it may occur too frequently to be explicable by chance alone. When spike synchrony above chances levels is present, it may subserve computation for a specific cognitive process, or it could be an irrelevant byproduct of such computation. Either way, spike synchrony is a feature of neural data that should be explained. A point process regression framework has been developed previously for this purpose, using generalized linear models (GLMs). In this framework, the observed number of synchronous spikes is compared to the number predicted by chance under varying assumptions about the factors that affect each of the individual neuron's firing-rate functions. An important possible source of spike synchrony is network-wide oscillations, which may provide an essential mechanism of network information flow. To establish the statistical link between spike synchrony and network-wide oscillations, we have integrated oscillatory field potentials into our point process regression framework. We first extended a previously-published model of spike-field association and showed that we could recover phase relationships between oscillatory field potentials and firing rates. We then used this new framework to demonstrate the statistical relationship between oscillatory field potentials and spike synchrony in: 1) simulated neurons, 2) in vitro recordings of hippocampal CA1 pyramidal cells, and 3) in vivo recordings of neocortical V4 neurons. Our results provide a rigorous method for establishing a statistical link between network oscillations and neural synchrony.

Efficient Estimation of Stochastic Volatility Using Noisy Observations: A Multi-Scale Approach

description: With the availability of high frequency financial data, nonparametric estimation of volatility of an asset return process becomes feasible. A major problem is how to estimate the volatility consistently and efficiently, when the observed asset returns contain error or noise, for example, in the form of microstructure noise. The former (consistency) has been addressed in the recent literature. However, the resulting estimator is not efficient. In Zhang, Mykland, and Aıt-Sahalia (2005), the best estimator converges to the true volatility only at the rate of n−1/6. In this paper, we propose an estimator, the Multi-scale Realized Volatility (MSRV), which converges to the true volatility at the rate of n−1/4, which is the best attainable. We have shown a central limit theorem for the MSRV estimator, which permits setting intervals for the true integrated volatility on the basis of MSRV.
Flavor-Safe Light Squarks in Higgs-Anomaly Mediation

description: We consider a simple setup with light squarks which is free from the gravitino and SUSY flavor problems. In our setup, a SUSY breaking sector is sequestered from the matter and gauge sectors, and it only couples to the Higgs sector directly with $\mathcal{O}(100)\,$TeV gravitino. Resulting mass spectra of sfermions are split: the first and second generation sfermions are light as $\mathcal{O}(1)\,$TeV while the third generation sfermions are heavy as $\mathcal{O}(10)\,$TeV. The light squarks of $\mathcal{O}(1)\,$TeV can be searched at the (high-luminosity) LHC and future collider experiments. Our scenario can naturally avoid too large flavor-changing neutral currents and it is consistent with the $ε_K$ constraint. Moreover, there are regions explaining the muon $g-2$ anomaly and bottom-tau/top-bottom-tau Yukawa coupling unification simultaneously.

description: The paper considers Edgeworth expansions for estimators of volatility. Unlike the usual expansions, we have found that in order to obtain meaningful terms, one needs to let the size of the noise to go zero asymptotically. This is reflected in our expansions. The results have application to Cornish-Fisher inversion and bootstrapping.
