description: Motivated by recent experimental progress in the context of ultra-cold multi-color fermionic atoms in optical lattices, we have developed a method to exactly diagonalize the Heisenberg $SU(N)$ Hamiltonian with several particles per site living in a fully symmetric or antisymmetric representation of $SU(N)$. The method, based on the use of standard Young tableaux, takes advantage of the full $SU(N)$ symmetry, allowing one to work directly in each irreducible representations of the global $SU(N)$ group. Since the $SU(N)$ singlet sector is often much smaller than the full Hilbert space, this enables one to reach much larger system sizes than with conventional exact diagonalizations. The method is applied to the study of Heisenberg chains in the symmetric representation with two and three particles per site up to $N=10$ and up to 20 sites. For the length scales accessible to this approach, all systems except the Haldane chain ($SU(2)$ with two particles per site) appear to be gapless, and the central charge and scaling dimensions extracted from the results are consistent with a critical behaviour in the $SU(N)$ level $k$ Wess-Zumino-Witten universality class, where $k$ is the number of particles per site. These results point to the existence of a cross-over between this universality class and the asymptotic low-energy behavior with a gapped spectrum or a critical behavior in the $SU(N)$ level $1$ WZW universality class.

description: We present an ensemble approach for categorizing search query entities in the recruitment domain. Understanding the types of entities expressed in a search query (Company, Skill, Job Title, etc.) enables more intelligent information retrieval based upon those entities compared to a traditional keyword-based search. Because search queries are typically very short, leveraging a traditional bag-of-words model to identify entity types would be inappropriate due to the lack of contextual information. Our approach instead combines clues from different sources of varying complexity in order to collect real-world knowledge about query entities. We employ distributional semantic representations of query entities through two models: 1) contextual vectors generated from encyclopedic corpora like Wikipedia, and 2) high dimensional word embedding vectors generated from millions of job postings using word2vec. Additionally, our approach utilizes both entity linguistic properties obtained from WordNet and ontological properties extracted from DBpedia. We evaluate our approach on a data set created at CareerBuilder; the largest job board in the US. The data set contains entities extracted from millions of job seekers/recruiters search queries, job postings, and resume documents. After constructing the distributional vectors of search entities, we use supervised machine learning to infer search entity types. Empirical results show that our approach outperforms the state-of-the-art word2vec distributional semantics model trained on Wikipedia. Moreover, we achieve micro-averaged F 1 score of 97% using the proposed distributional representations ensemble.

description: Understanding the covalent clathrate formation is a crucial point for the design of new superhard materials with intrinsic coupling of superhardness and metallic conductivity. Silicon clathrates have the archetype structures that can serve an existant model compounds for superhard clathrate frameworks "Si-B", "Si-C", "B-C" and "C" with intercalated atoms (e.g. alkali metals or even halogenes) that can assure the metalic properties. Here we report the in situ and ex situ studies of high-pressure formation and stability of clathrates Na8Si46 (structure I) and Na24+xSi136 (structure II). Experiments have been performed using standard Paris-Edinburgh cells (opposite anvils) up to 6 GPa and 1500 K. We have established that chemical interactions in Na-Si system and transition between two structures of clathrates occur at temperatures below silicon melting. The strong sensitivity of crystallization products to the sodium concentration have been observed. A tentative diagram of clathrate transformations has been proposed. At least up to ~6 GPa, Na24+xSi136 (structure II) is stable at lower temperatures as compared to Na8Si46 (structure I).
Counting multiplicities of Dirichlet eigenvalues

Publisher: name: No Publisher Supplied
Year: 2023

description: The problem of explicitly computing eigenvalues of the Dirichlet Laplacian on two dimensional domains is in general very difficult.However, for certain highly symmetric domains it is possible to obtain closed-form expressions for eigenvalues. In the case of rectangular domains not only does such a closed-form expression exist, but it also happens to coincide with the formula for integer points on an ellipse. Establishing criteria for the existence of such points as well as determining their multiplicity was a major driving force in the development of 18th and 19th century number theory, leading to the Law of Quadratic Reciprocity, the Hilbert-Waring theorem, the Gauss circle problem, and many other theorems and conjectures. The goal of this thesis is to use some of these classical number-theoretic results to answer a question about multiplicities of Dirichlet eigenvalues on certain special rectangles. Specifically, we show that on these rectangles the set of multiplicities of Dirichlet eigenvalues is equal to the whole of N.

description: The $n$-species totally asymmetric zero range process ($n$-TAZRP) on one-dimensional periodic chain studied recently by the authors is a continuous time Markov process where arbitrary number of particles can occupy the same sites and hop to the adjacent sites only in one direction with a priority constraint according to their species. In this paper we introduce an $n$-parameter generalization of the $n$-TAZRP having inhomogeneous transition rate. The steady state probability is obtained in a matrix product form and also by an algorithm related to combinatorial $R$.

Examining predictors of job-related passion within the context of a narrative model of strongly held beliefs
Creators: name: Perez, Alberly

description: Organizations aim to attract and retain those who are driven to perform their job responsibilities. The existing literature has highlighted the positive outcomes of work passion (e.g., higher performance; Dubreuil et al., 2014), as well as its possible negative consequences (e.g., burnout; Lavigne et al., 2012). However, limited research has investigated the factors that predict work passion. Drawing from an integrative Narrative Model of Strongly Held Beliefs (Roseman, 1994), we examined whether belief components (evaluative, behavioral, identificational, normative, and explanatory components); single-item emotion intensity ratings of hope and pride (Roseman et al., 2015); and meaningful work (assessed through the Work and Meaning Inventory; Steger, 2012) predicted job-related passion. We hypothesized that the belief components, hope, pride, and meaningful work would positively predict job-related passion. A total of 102 full-time employed adults (defined as usually working 35 hours or more per week at their primary job) from select occupational backgrounds were recruited from Amazon Mechanical Turk and a listserv of Rutgers University-Camden alumni. Participants completed a single-occasion, self-report questionnaire via Qualtrics. Job-related passion was measured using one of the Passion Validity Criteria items (Vallerand & Houlfort, 2003), a single-item Job Passion Rating (Roseman et al., 2015), and the Work Passion Scale (Chen et al., 2020). Multiple regression analyses were conducted to test our hypotheses. Results show that the identificational component, pride, and meaningful work were the most consistent predictors of job-related passion. Implications for organizational training programs geared towards increasing passionate job motivation are discussed. Study limitations and future directions are also considered.

description: Colombia ha experimentado una ampliación de los espacios de participación ciudadana, que tienen por objeto la legitimación de las instituciones estatales y la interacción directa de los ciudadanos. Sin embargo, a pesar de que lo anterior debería suponer mayor intervención comunitaria en los asuntos públicos, la realidad es completamente disímil y no se ha podido alcanzar el aspecto teleológico de la institucionalización de los mecanismos referidos. En este sentido, se crean las Juntas Administradoras Locales, ley 11 de 1886, actualizada con las leyes 617 del 2000 y 1551 de 2012, las cuales tienen por finalidad, servir como vínculo entre la ciudadanía y la administración, convirtiéndose en el escenario idóneo para escuchar y atender los intereses y necesidades de la comunidad. Empero, las referidas no han tenido el resultado esperado debido a múltiples factores que lo han imposibilitado, desde la inoperancia de las administraciones para instituirlas, hasta su falta de financiamiento y el marcado abstencionismo electoral que han sufrido. Es así como la legitimidad política entra en un limbo entre el interés ciudadano, el conocimiento político, la falta de armonía entre el ejercicio político por parte de la entes públicos y, en consecuencia, la insatisfacción de las necesidades colectivas.

description: GK Persei (1901, the 'Firework Nebula') is an old but bright nova remnant that offers a chance to probe the physics and kinematics of nova shells. The kinematics in new and archival longslit optical echelle spectra were analysed using the shape software. New imaging from the Aristarchos telescope continues to track the proper motion, extinction and structural evolution of the knots, which have been observed intermittently over several decades. We present for the first time, kinematical constraints on a large faint 'jet' feature, that was previously detected beyond the shell boundary. These observational constraints allow for the generation of models for individual knots, interactions within knot complexes, and the 'jet' feature. Put together, and taking into account dwarf-nova accelerated winds emanating from the central source, these data and models give a deeper insight into the GK Per nova remnant as a whole.

THE ROLE OF RNA AND DNA:RNA HYBRIDS AT DNA DOUBLE-STRAND BREAKS
Creators: name: D'ALESSANDRO, GIUSEPPINA
Publisher: name: Universit� degli Studi di Milano
Year: 2018

description: The stability of our genome is constantly challenged by several genotoxic threats. DNA double-strand breaks (DSBs) are the most dangerous DNA lesions that, if not repaired, can lead to cancer initiation and progression and/or ageing. These detrimental consequences can only be avoided if cells promptly recognize the lesions and signal their presence, thus promoting either efficient repair and transient cell cycle arrest or cell death and cellular senescence. This is the role of the DNA damage response (DDR) proteins and the newly identified damage-induced non coding RNAs. We recently discovered that RNA polymerase II is recruited to DSBs and synthetizes damage-induced non-coding RNAs (dilncRNAs). DROSHA- and DICER-mediated processing of dilncRNAs generates small RNA species, named DNA damage response RNA (DDRNAs) (Francia, 2012), that localize to DSBs via pairing with dilncRNAs and promote DDR signaling (Michelini et al., in press). Similar small non-coding RNA species discovered in plants are involved in DNA repair by homologous recombination (HR) (Wei, 2012, Gao, 2014, Wang, 2016). In line with these results, I report that transcriptional inhibition impairs recruitment of the HR proteins BRCA1, BRCA2, and RAD51 to DSBs, while partially promoting DNA end resection. Moreover, I show DNA:RNA hybrids accumulation at DSBs in mammalian cells by both DRIP analyses and imaging techniques. Damage-induced DNA:RNA hybrids form upon the hybridization of RNA species, likely dilncRNAs, to the resected DSBs DNA ends generated during the S/G2 cell cycle phase. I also report that purified recombinant BRCA1 binds DNA:RNA hybrids in vitro; moreover, DNA:RNA hybrids in vivo contribute to BRCA1 recruitment to DSBs. Consistent with the need to tightly regulate DNA:RNA hybrid levels, I demonstrate that RNase H2, the major RNase H activity in mammalian nuclei, is recruited to DSBs through direct interaction with RAD51. In summary, I report for the first time that DNA:RNA hybrids accumulate at DSBs in mammalian cells in a cell-cycle- and DNA end resection-depended way. At DSBs, BRCA1 directly recognizes DNA:RNA hybrids and likely controls their turn-over by mediating the recruitment of RNase H2 via RAD51.

description: The US has a "patchwork" of specific and non-specific laws that directly or incidentally govern moral rights. This article focuses on a subset of this patchwork, contracts and copyright, and examines the utilitarian implications of effectuating attribution and integrity moral rights through the two ("contracts-based moral rights"). The article will examine the advantages and disadvantages of contracts-based moral rights by contrasting the examples of academic and trade public publishing. Ultimately, this article argues that the patchwork's limitations are likely to affect the creative incentives of only a subset of authors: sophisticated but poorly resourced ones. However, the contract-based system is also more likely to generate ex-post psychic harms from the moral rights violations.

description: We present a first look at the SCUBA-2 observations of three sub-regions of the Orion B molecular cloud: LDN 1622, NGC 2023/2024, and NGC 2068/2071, from the JCMT Gould Belt Legacy Survey. We identify 29, 564, and 322 dense cores in L1622, NGC 2023/2024, and NGC 2068/2071 respectively, using the SCUBA-2 850 micron map, and present their basic properties, including their peak fluxes, total fluxes, and sizes, and an estimate of the corresponding 450 micron peak fluxes and total fluxes, using the FellWalker source extraction algorithm. Assuming a constant temperature of 20 K, the starless dense cores have a mass function similar to that found in previous dense core analyses, with a Salpeter-like slope at the high-mass end. The majority of cores appear stable to gravitational collapse when considering only thermal pressure; indeed, most of the cores which have masses above the thermal Jeans mass are already associated with at least one protostar. At higher cloud column densities, above 1-2 x 10^23 cm^-2, most of the mass is found within dense cores, while at lower cloud column densities, below 1 x 10^23 cm^-2, this fraction drops to 10% or lower. Overall, the fraction of dense cores associated with a protostar is quite small (<8%), but becomes larger for the densest and most centrally concentrated cores. NGC 2023 / 2024 and NGC 2068/2071 appear to be on the path to forming a significant number of stars in the future, while L1622 has little additional mass in dense cores to form many new stars.

description: This study examines the application of commitment procedures in one urban community in Virginia. The study investigated: the concordance rates of clinical recommendation for treatment and the outcome of the commitment hearing. the time lapse between detention of an individual and the hearing outcome. the presenting symptomatology and outcome. and the pre-detention compliance to treatment and outcome. The study's findings showed a concordance rate of 64% between clinical recommendation and outcome. It provided no significant differences in symptomatology/outcome. compliance/outcome. and time lapse/outcome. The lack of any significant findings seems to suggest that application of commitment laws might benefit from institution of clearer guidelines. In addition, a more meaningful outpatient commitment law in Virginia might facilitate a "least restrictive alternative" for the chronically mentally ill population.

description: We present an updated version of the spectroscopic catalogue of white dwarf-main sequence (WDMS) binaries from the Sloan Digital Sky Survey (SDSS). We identify 939 WDMS binaries within the data releases (DR) 9-12 of SDSS plus 40 objects from DR 1-8 that we missed in our previous works, 646 of which are new. The total number of spectroscopic SDSS WDMS binaries increases to 3294. This is by far the largest and most homogeneous sample of compact binaries currently available. We use a decomposition/fitting routine to derive the stellar parameters of all systems identified here (white dwarf effective temperatures, surface gravities and masses, and secondary star spectral types). The analysis of the corresponding stellar parameter distributions shows that the SDSS WDMS binary population is seriously affected by selection effects. We also measure the NaI 8183.27, 8194.81 absorption doublet and Halpha emission radial velocities (RV) from all SDSS WDMS binary spectra identified in this work. 98 objects are found to display RV variations, 62 of which are new. The RV data are sufficient enough to estimate the orbital periods of three close binaries.

description: Let $\mathcal{S}$ be a connected planar polygonal subdivision with $n$ edges that we want to preprocess for point-location queries, and where we are given the probability $γ_i$ that the query point lies in a polygon $P_i$ of $\mathcal{S}$. We show how to preprocess $\mathcal{S}$ such that the query time for a point~$p\in P_i$ depends on~$γ_i$ and, in addition, on the distance from $p$ to the boundary of~$P_i$---the further away from the boundary, the faster the query. More precisely, we show that a point-location query can be answered in time $O\left(\min \left(\log n, 1 + \log \frac{\mathrm{area}(P_i)}{γ_i Δ_{p}^2}\right)\right)$, where $Δ_{p}$ is the shortest Euclidean distance of the query point~$p$ to the boundary of $P_i$. Our structure uses $O(n)$ space and $O(n \log n)$ preprocessing time. It is based on a decomposition of the regions of $\mathcal{S}$ into convex quadrilaterals and triangles with the following property: for any point $p\in P_i$, the quadrilateral or triangle containing~$p$ has area $Ω(Δ_{p}^2)$. For the special case where $\mathcal{S}$ is a subdivision of the unit square and $γ_i=\mathrm{area}(P_i)$, we present a simpler solution that achieves a query time of $O\left(\min \left(\log n, \log \frac{1}{Δ_{p}^2}\right)\right)$. The latter solution can be extended to convex subdivisions in three dimensions.

In this paper we study the order of magnitude of the cross-correlation measure $Φ_k(\mathcal{F})$ for typical families. We prove that, for most families $\mathcal{F} \subset \{-1,1\}^N$ of size $2\leq |\mathcal{F}|<2^{N/12}$, $Φ_k(\mathcal{F})$ is of order $\sqrt{N\log \binom{N}{k}+k\log |\mathcal{F}|}$ for any given $2\leq k \leq N/(6\log_2 |\mathcal{F}|)$.

LGBTQ+ community college students’ facilitators & barriers to sexual health

description: Purpose: To collect information from LGBTQ+ community college students about perceived facilitators and barriers to sexual health resources to develop a sexual health protocol to reduce barriers for LGBTQ+ students. Methods: The anonymous, forty-question, web-based survey aims to collect demographic, social determinant, and subjective information from fifteen LGBTQ+ county college students. Students completed the one-time survey during the rolling 30-day collection period. Data was collected with Qualtrics and analyzed with Qualtrics and SPSS for descriptive statistics and thematic analysis. IRB approval was obtained from Rutgers Biomedical and Health Sciences. Results: The evidence displayed various student-experienced barriers, including inadequate LGBTQ+ inclusive and relevant sexual health education and insufficient knowledge of safe sex practices as displayed by high-risk sexual behavior, and decreased visibility of on-campus and community or social organization resources. The most significant facilitator was that all (100%) students reported feeling their school was safe and accepting for the LGBTQ+ community. The evidence identifies deficiencies in sexual health education and resources among the LGBTQ+ community college population and the relationship between these deficiencies and high-risk sexual health behaviors. Implications for practice: Community colleges can provide LGBTQ+ students with sexual health resources to help positively influence safe sexual health behaviors to reduce sexual health disparities. As many respondents reported, they were unsure of existing available resources; increasing the visibility on and off-campus could aid in increasing accessibility. Additionally, partnering with community organizations could further increase accessibility to necessary resources by amplifying services and information the school does not provide. Furthermore, promoting a safe and accepting campus environment can help to promote positive sexual health outcomes, such as reducing STIs and unplanned pregnancies in this high-risk population. Educating health-care providers, such as those in student health, on why the need for LGBTQ+ inclusivity is essential, how inclusivity and affirming care can help to reduce sexual health disparities, and how the providers can become more inclusive and affirming in the care that they provide, can positively impact sexual health by promoting a safe and accepting campus environment and increasing access and visibility of necessary resources.

description: We report the operation of a cold-atom inertial sensor which continuously captures the rotation signal. Using a joint interrogation scheme, where we simultaneously prepare a cold-atom source and operate an atom interferometer (AI) enables us to eliminate the dead times. We show that such continuous operation improves the short-term sensitivity of AIs, and demonstrate a rotation sensitivity of $100\ \text{nrad.s}^{-1}.\text{Hz}^{-1/2}$ in a cold-atom gyroscope of $11 \ \text{cm}^2$ Sagnac area. We also demonstrate a rotation stability of $1 \ \text{nrad.s}^{-1}$ at $10^4$ s of integration time, which establishes the record for atomic gyroscopes. The continuous operation of cold-atom inertial sensors will enable to benefit from the full sensitivity potential of large area AIs, determined by the quantum noise limit.

description: Isotope shifts of the 2$p_{3/2}$-2$p_{1/2}$ transition in B-like ions are evaluated for a wide range of the nuclear charge number: Z=8-92. The calculations of the relativistic nuclear recoil and nuclear size effects are performed using a large scale configuration-interaction Dirac-Fock-Sturm method. The corresponding QED corrections are also taken into account. The results of the calculations are compared with the theoretical values obtained with other methods. The accuracy of the isotope shifts of the 2$p_{3/2}$-2$p_{1/2}$ transition in B-like ions is significantly improved.

BOND: Bayesian Oxygen and Nitrogen abundance Determinations in giant H II regions using strong and semi-strong lines

description: We present BOND, a Bayesian code to simultaneously derive oxygen and nitrogen abundances in giant H II regions. It compares observed emission lines to a grid of photoionization models without assuming any relation between O/H and N/O. Our grid spans a wide range in O/H, N/O and ionization parameter U, and covers different starburst ages and nebular geometries. Varying starburst ages accounts for variations in the ionizing radiation field hardness, which arise due to the ageing of H II regions or the stochastic sampling of the initial mass function. All previous approaches assume a strict relation between the ionizing field and metallicity. The other novelty is extracting information on the nebular physics from semi-strong emission lines. While strong lines ratios alone ([O III]/Hbeta, [O II]/Hbeta and [N II]/Hbeta) lead to multiple O/H solutions, the simultaneous use of [Ar III]/[Ne III] allows one to decide whether an H II region is of high or low metallicity. Adding He I/Hbeta pins down the hardness of the radiation field. We apply our method to H II regions and blue compact dwarf galaxies, and find that the resulting N/O vs O/H relation is as scattered as the one obtained from the temperature-based method. As in previous strong-line methods calibrated on photoionization models, the BOND O/H values are generally higher than temperature-based ones, which might indicate the presence of temperature fluctuations or kappa distributions in real nebulae, or a too soft ionizing radiation field in the models.

title: Global rule of law support and problems in implementation - An analysis of rule of law supporting activities of the World Bank and the Inter-American Court of Human Rights in Peru and Argentina
Creators: name: Liebermann, Julia
Publisher: name: UNSPECIFIED
Year: 2024

description: A great deal of controversy exists about what the rule of law as a state ordering concept and a morally guiding principle for governance comprises. Even more so, global activities for supporting rule of law are debated. This study turns to implementation problems in two kinds of global rule of law support: financial development projects of the World Bank and human rights judgements of the Inter-American Court of Human Rights. In a thorough analysis of the dimensions of context, design and coordination, the study traces implementation processes in Peru and Argentina between 1998 and 2018. The study criticizes narrow conceptualizations of rule of law support in international governance guided by eurocentrism and hierarchical implementation procedures. The study develops the concept of constitutive moments for transformation and suggests the degree of deliberation, self-determination and representation as a framework for assessment. Arguing that conflictive processes and processes relating to reordering the separation of powers among branches can bear constitutive moments for rule of law development, the study makes a plea for processes to be repoliticized to allow for new conceptualizations of rule of law.
The Mumford-Tate conjecture for the product of an abelian surface and a K3 surface

description: In this paper we prove the Mumford-Tate conjecture in degree 2 for the product of an abelian surface $A$ and a K3 surface $X$ over a finitely generated field $K \subset \mathbb{C}$. The Mumford-Tate conjecture is a precise way of saying that the Hodge structure on singular cohomology conveys the same information as the Galois representation on $\ell$-adic étale cohomology. To make this precise, let $G_{\mathrm{B}}$ be the Mumford-Tate group of the Hodge structure $H^{2}_{\text{sing}}(A(\mathbb{C}) \times X(\mathbb{C}), \mathbb{Q})$. Let $G_{\ell}^{\circ}$ be the connected component of the identity of the Zariski closure of the image of the Galois group $\textrm{Gal}(\bar{K}/K)$ in $\mathrm{GL}(H^{2}_{\text{ét}}(A_{\bar{K}} \times X_{\bar{K}}, \mathbb{Q}_{\ell}))$. The Mumford-Tate conjecture asserts that $G_{\mathrm{B}} \otimes \mathbb{Q}_{\ell} \cong G_{\ell}^{\circ}$. The proof presented in this paper uses input from number theory (Chebotaryov's density theorem), Lie theory, and some facts about K3 surfaces over finite fields.

Topological energy gaps in the [111]-oriented InAs/GaSb and GaSb/InAs core-shell nanowires

description: The [111]-oriented InAs/GaSb and GaSb/InAs core-shell nanowires have been studied by the $8\times 8$ Luttinger-Kohn $\vec{k}\cdot\vec{p}$ Hamiltonian to search for non-vanishing fundamental gaps between inverted electron and hole bands. We focus on the variations of the topologically nontrivial fundamental gap, the hybridization gap, and the effective gap with the core radius and shell thickness of the nanowires. The evolutions of all the energy gaps with the structural parameters are shown to be dominantly governed by quantum size effects. With a fixed core radius, a topologically nontrivial fundamental gap exists only at intermediate shell thicknesses. The maximum gap is $\sim 4.4$ meV for GaSb/InAs and $\sim 3.5$ meV for InAs/GaSb core-shell nanowires, and for the GaSb/InAs core-shell nanowires the gap persists over a wider range of geometrical parameters. The intrinsic reason for these differences between the two types of nanowires is that in the shell the electron-like states of InAs is more delocalized than the hole-like state of GaSb, while in the core the hole-like state of GaSb is more delocalized than the electron-like state of InAs, and both features favor stronger electron-hole hybridization. Since similar features of the electron- and hole-like states have been found in nanowires of other materials, it could serve as a common rule to put the hole-like state in the core while the electron-like state in the shell of a core-shell nanowire to achieve better topological properties.
