description: Filaments and coronal holes, two principal features observed in the solar corona are sources of space weather variations. Filament formation is closely associated with polarity inversion lines (PIL) on the solar photosphere which separate positive and negative polarities of the surface magnetic field. The origin of coronal holes is governed by large-scale unipolar magnetic patches on the photosphere from where open magnetic field lines extend to the heliosphere. We study properties of filaments, PILs and coronal holes in solar cycles 20, 21, 22 and 23 utilizing the McIntosh archive. We detect a prominent cyclic behavior of filament length, PIL length, and coronal hole area with significant correspondence with the solar magnetic cycle. The spatio-temporal evolution of the geometric centers of filaments shows a butterfly-like structure and distinguishable pole-ward migration of long filaments during cycle maxima. We identify this rush to the poles of filaments to be co-temporal with the initiation of polar field reversal as gleaned from Mount Wilson and Wilcox Solar Observatory polar field observations and quantitatively establish their temporal correspondence. We analyze the filament tilt angle distribution to constrain their possible origins. Majority of the filaments exhibit negative and positive tilt angles in the northern and the southern hemispheres, respectively -- strongly suggesting that their formation is governed by the overall large-scale magnetic field distribution on the solar photosphere and not by the small-scale intra-active region magnetic field configurations. We also investigate the hemispheric asymmetry in filaments, PILs, and coronal holes. We find that the hemispheric asymmetry in filaments and PILs are positively correlated -- whereas coronal hole asymmetry is uncorrelated -- with sunspot area asymmetry.

description: We study a quantum mechanical potential introduced previously as a conditionally exactly solvable (CES) model. Besides an analysis following its original introduction in terms of the point canonical transformation, we also present an alternative supersymmetric construction of it. We demonstrate that from the three roots of the implicit cubic equation defining the bound-state energy eigenvalues, there is always only one that leads to a meaningful physical state. Finally we demonstrate that the present CES interaction is, in fact, an exactly solvable Natanzon-class potential.

description: The purpose of this study is to examine the effect of different length carbon plate in modern racing shoes on participants running economy (RE). The three shoe conditions were full length carbon fiber plate using the Nike Vaporfly, a half carbon plate shoe with the Skechers Speed Elite, and no carbon fiber plate with the Skechers Razor 3. Participants ran on a treadmill at speeds 5-10% above and below their ventilatory threshold. This pace was determined in a previous visit in which participants completed a VO2max test. Participants ran in each shoe for five minutes twice at each speed. Eight women completed the study. During the running segments, VO2, HR, and RPE were taken. Results indicate the Nike Vaporfly affected running RE greater than the other two shoes demonstrating this shoe may be the better shoe to use for women for their running performance.

description: We investigate the effects of disorder on a layered superconductor. The clean system is known to have a first order phase transition which is clearly identified by a sharp peak in the specific heat. The peak is lost abruptly as the strength of the disorder is increased. Hence, for strong disorder there is no phase transition as a function of temperature but merely a crossover which is still detectable in the IV characteristic.

description: We give a consistent description of how the inflationary Universe emerges in quantum cosmology. This involves two steps: Firstly, it is shown that a sensible probability peak can be obtained from the cosmological wave function. This is achieved by going beyond the tree level of the semiclassical expansion. Secondly, due to decoherence interference terms between different semiclassical branches are negligibly small. The results give constraints on the particle content of a unified theory.

description: We analyzed the effect of frequent measurements on the quantum systems that are chaotic in the classical limit. It is shown that the kicked rotator, a well-known example of quantum chaos, is too special to be used as a testing ground for the effects of the repeated measurements. The abrupt change of state vectors by the delta-kick singular interruptions causes a quantum anti-Zeno effect. However, in more realistic systems with interaction potentials of continuous time dependence the quantum Zeno effect prevails.

description: This paper presents the IMS contribution to the PolEval 2018 Shared Task. We submitted systems for both of the Subtasks of Task 1. In Subtask (A), which was about dependency parsing, we used our ensemble system from the CoNLL 2017 UD Shared Task. The system first preprocesses the sentences with a CRF POS/morphological tagger and predicts supertags with a neural tagger. Then, it employs multiple instances of three different parsers and merges their outputs by applying blending. The system achieved the second place out of four participating teams. In this paper we show which components of the system were the most responsible for its final performance. The goal of Subtask (B) was to predict enhanced graphs. Our approach consisted of two steps: parsing the sentences with our ensemble system from Subtask (A), and applying 12 simple rules to obtain the final dependency graphs. The rules introduce additional enhanced arcs only for tokens with "conj" heads (conjuncts). They do not predict semantic relations at all. The system ranked first out of three participating teams. In this paper we show examples of rules we designed and analyze the relation between the quality of automatically parsed trees and the accuracy of the enhanced graphs.
Adaptive learning by extremal dynamics and negative feedback

subject: FOS: Biological sciences

description: We describe a mechanism for biological learning and adaptation based on two simple principles: (I) Neuronal activity propagates only through the network's strongest synaptic connections (extremal dynamics), and (II) The strengths of active synapses are reduced if mistakes are made, otherwise no changes occur (negative feedback). The balancing of those two tendencies typically shapes a synaptic landscape with configurations which are barely stable, and therefore highly flexible. This allows for swift adaptation to new situations. Recollection of past successes is achieved by punishing synapses which have once participated in activity associated with successful outputs much less than neurons that have never been successful. Despite its simplicity, the model can readily learn to solve complicated nonlinear tasks, even in the presence of noise. In particular, the learning time for the benchmark parity problem scales algebraically with the problem size N, with an exponent $k\sim 1.4$.

description: We study congruences between cuspidal modular forms and Eisenstein series at levels which are square-free integers and for equal even weights. This generalizes our previous results from Naskręcki [17] for prime levels and provides further evidence for the sharp bounds obtained under restrictive ramification conditions. We prove an upper bound on the exponent in the general square-free situation and also discuss the existence of the congruences when the coefficients belong to the rational numbers and weight equals 2.

description: We present new results concerning the existence of static, electrically charged, perfect fluid spheres that have a regular interior and are arbitrarily close to a maximally charged black-hole state. These configurations are described by exact solutions of Einstein's field equations. A family of these solutions had already be found (de Felice et al., 1995) but here we generalize that result to cases with different charge distribution within the spheres and show, in an appropriate parameter space, that the set of such physically reasonable solutions has a non zero measure. We also perform a perturbation analysis and identify the solutions which are stable against adiabatic radial perturbations. We then suggest that the stable configurations can be considered as classic models of charged particles. Finally our results are used to show that a conjecture of Kristiansson et al. (1998) is incorrect.

Moreover, we also give a simple minimax characterization of the ground state energy. Our results improve and complement previous ones in the literature.

description: « Du tacite à l’explicite » (atelier n°5) a abordé le thème des JNF 2024 par le prisme de l’expertise étudiante : mieux cerner les besoins de ce public doit d’abord passer par une meilleure connaissance de ce qu’ils savent déjà, au sens le plus large. 

Nous avons proposé aux participants de s’arrêter sur deux questions (tout sauf) simples : 1. Temps individuel = Qu’est-ce que les étudiants doivent savoir pour évoluer dans leur vie universitaire ?2. Réflexion en groupes = Quels moyens pouvons-nous imaginer pour atteindre ce savoir, voire développer la même expertise ?

Voilà ce qui ressort de ce moment :- Alors que les bibliothécaires s’inquiètent traditionnellement de leur maitrise du savoir technique ou disciplinaire dans la préparation des formations, c’est en réalité le volet « vie étudiante » qui représente l’impensé de l’expertise étudiante et qui a provoqué le plus de discussions. - Par ailleurs, les collègues mettent en lumière la nécessité de l’immersion dans certains aspects de la vie des étudiants pour mieux comprendre leurs besoins.

La dernière partie de l’atelier a permis de faire un pas de côté en revenant sur les entretiens menés auprès des tutrices-étudiantes de la BU de Sceaux, qui tentaient d’expliciter leur expertise concernant les “vrais” besoins des étudiants.

Nous préparons une restitution plus détaillée, ainsi que d’autres travaux issus de ces premières réflexions.

Sont déposés ici : - une version numérique du paper-board suite au temps de réflexion individuel sur le contenu du savoir étudiant ;- une visualisation du regroupement des idées et de la façon dont les trois grandes thématiques ont émergé ;- une visualisation du travail des collègues suite à la définition de ces trois thématiques ;- une version numérique des paper-board de chaque thématique = matériel et outils ; disciplinaire et attendus enseignants ; vie étudiante ;- un extrait des entretiens menés auprès des tutrices ;- le guide d'entretien auprès des tutrices ;- la bibliographie qui a servi de fondement à la réflexion sur les savoirs tacites et l’implicite ;- la liste des mots-clés reprenant les concepts issus de la philosophie et la sociologie des sciences.

description: Data selection techniques applied to neural machine translation (NMT) aim to increase the performance of a model by retrieving a subset of sentences for use as training data. One of the possible data selection techniques are transductive learning methods, which select the data based on the test set, i.e. the document to be translated. A limitation of these methods to date is that using the source-side test set does not by itself guarantee that sentences are selected with correct translations, or translations that are suitable given the test-set domain. Some corpora, such as subtitle corpora, may contain parallel sentences with inaccurate translations caused by localization or length restrictions. In order to try to fix this problem, in this paper we propose to use an approximated target-side in addition to the source-side when selecting suitable sentence-pairs for training a model. This approximated target-side is built by pre-translating the source-side. In this work, we explore the performance of this general idea for one specific data selection approach called Feature Decay Algorithms (FDA). We train German-English NMT models on data selected by using the test set (source), the approximated target side, and a mixture of both. Our findings reveal that models built using a combination of outputs of FDA (using the test set and an approximated target side) perform better than those solely using the test set. We obtain a statistically significant improvement of more than 1.5 BLEU points over a model trained with all data, and more than 0.5 BLEU points over a strong FDA baseline that uses source-side information only.

Social Network Density Predicts Partisan Animosity
Creators: name: Wilbanks, Danica
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2024

description: The United States is grappling with rising partisan animosity and the fracturing of community ties. While these trends are often considered in isolation, three studies explore the connection between the structure of social networks and partisan animosity in the United States. These studies build on the premise that people use their local social environments (i.e., their friends and family) to make sense of more distal environments (i.e., the nation). We hypothesize that people in dense social networks feel a sense of unity with their close friends and family, then project this unity on the country, which predicts higher warmth and openness to political opponents. Study 1 supports this model with a representative sample of Americans, and Study 2 further supports this model via an attempt to manipulate perceived network density. Study 3 leverages nationwide county-level data from the Social Capital Atlas and Project Implicit to reveal that communities with higher social network density exhibit lower partisan animosity. The present findings suggest that considering the overarching structures of social networks is crucial to understanding partisan animosity, and that encouraging social cohesion may help mend political divides.

description: Quantum key distribution (QKD) offers a secret way to share keys between legitimate users which is guaranteed by the law of quantum mechanics. Most recently, the limitation of transmission distance without quantum repeaters was broken through by twin-field QKD [Nature (London) 557, 400 (2018)]. Based on its main idea, sending or not-sending (SNS) QKD protocol was proposed [Phys. Rev. A 98, 062323 (2018)], which filled the remaining security loopholes and can tolerate large misalignment errors. In this paper, we give a more general model for SNS QKD, where the two legitimate users, Alice and Bob, can possess asymmetric quantum channels. By applying the method present in the work, the legitimate users can achieve dramatically increased key generation rate and transmission distance compared with utilizing the original symmetric protocol. Therefore, our present work represents a further step along the progress of practical QKD.

description: One of the largest surprises from the LIGO results regarding the first gravitational wave detection (GW 150914) was the fact the black holes (BHs) were "heavy", of order 30 - 40 solar masses. The most promising explanation for this obesity is that the BH-BH merger occurred at low metallicity (Z): when the iron (Fe) contents is lower this is expected to result in weaker mass loss during the Wolf-Rayet (WR) phase. We therefore critically evaluate the claims for the reasons of heavy BHs as a function of Z in the literature. Furthermore, weaker stellar winds might lead to more rapid stellar rotation, allowing WR and BH progenitor evolution in a chemically homogeneous manner. However, there is as yet no empirical evidence for more rapid rotation amongst WR stars in the low Z environment of the Magellanic Clouds. Due to the intrinsic challenge of determining WR rotation rates from emission lines, the most promising avenue to constrain rotation-rate distributions amongst various WR subgroups is through the utilisation of their emission lines in polarised light. We thus provide an overview of linear spectro-polarimetry observations of both single and binary WRs in the Galaxy, as well as the Large and Small Magellanic Clouds, at 50% and 20% of solar Z, respectively. Initial results suggest that the route of chemically homogeneous evolution (CHE) through stellar rotation is challenging, whilst the alternative of a post-LBV or common envelope evolution is more likely.

description: We recently constructed a causal quantum mechanics in 2 dim. phase space which is more realistic than the de Broglie-Bohm mechanics as it reproduces not just the position but also the momentum probability density of ordinary quantum theory. Here we present an even more ambitious construction in 2n dim. phase space. We conjecture that the causal Hamiltonian quantum mechanics presented here is `maximally realistic'. The positive definite phase space density reproduces as marginals the correct quantum probability densities of $n+1$ different complete commuting sets of observables (e.g. $\vec q$, $\vec p$ and $n-1$ other sets). In general the particle velocities do not coincide with the de Broglie-Bohm velocities.

description: A time-of-flight (ToF) imaging system is proposed and its working principle demonstrated. To realize this system, a new device, a free-space optical mixer, is designed and fabricated. A scene is illuminated (flashed) with a megahertz level amplitude modulated light source and the reflected light from the scene is collected by a receiver. The receiver consists of the free-space optical mixer, comprising a photoelastic modulator sandwiched between polarizers, placed in front of a standard CMOS image sensor. This free-space optical mixer downconverts the megahertz level amplitude modulation frequencies into the temporal bandwidth of the image sensor. A full scale extension of the demonstrated system will be able to measure phases and Doppler shifts for the beat tones and use signal processing techniques to estimate the distance and velocity of each point in the illuminated scene with high accuracy.

description: $d^\ast(2380)$ was observed by WASA-at-COSY collaborations in the nuclear reaction recently. Its particularly narrow width may indicate the new QCD-allowed hadronic structure. To further confirm the existence of this peculiar particle in a totally different kind of reaction, we study the opportunity for searching $\bar{d}^\ast$ in the $Υ(nS)$ (with n=1, 2, 3) decay. As a phenomenological study, our framework is based on SU(3) chiral quark model. By virtue of the unitarity of $S$-matrix and crossing symmetry, we study the imaginary part of the forward scattering amplitudes between $Υ(nS)$ and $d^\ast$. The scattering process is mainly governed by the quark-meson interaction. We examine both the pseudoscalar and vector meson contribution in the intermediate state. Hopefully, our results show that it's quite possible to find $\bar{d}^\ast$ in this decay mode in the future.

description: Using Littlewood's map, which decomposes a partition into its $r$-core and $r$-quotient, Han and Ji have shown that many well-known hook-length formulas admit modular analogues. In this paper we present a variant of the Han-Ji `multiplication theorem' based on a new analogue of Littlewood's decomposition. We discuss several applications to hook-length formulas, one of which leads us to conjecture a modular analogue of the $q,t$-Nekrasov-Okounkov formula.

Copolymer Networks: Multifractal dimension spectra in polymer field theory

description: We explore the rich scaling behavior of copolymer networks in solution. We establish a field theoretic description in terms of composite operators. Our 3rd order resummation of the spectrum of scaling dimensions brings about remarkable features: Convexity of the spectra allows for a multifractal interpretation. This has not been conceived for power of field operators of $ϕ^4$ field theory before. The 2D limit of the mutually avoiding walk star apparently corresponds to results of a conformal Kac series. Such a classification seems not possible for the 2D limit of other copolymer stars. The 3rd order calculation of a large collection of exponents furthermore allows for a consistency check of two complementary schemes: epsilon expansion and renormalization at fixed dimension.

Divided by Design:  Education and Ethnonationalism in Bosnia and Herzegovina’s Fragile Peace
Creators: name: Kroening, Ermina Mujezinovic
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2024

description: This thesis provides an examination of the ethnically segregated education system in Bosnia and Herzegovina, a reflection of the country's deeply rooted ethnic divisions. The study highlights how the Dayton Peace Agreement, despite ending the Bosnian War, established a governance and education system that furthers ethnonationalism and examines the education system’s role in perpetuating this cycle. The country's fragmented ethnic landscape, an outcome of ethnic cleansing during the war, contributes to the reinforcement of identity politics, making schools a battleground for ethnic segregation. Tracing back to Bosnia's history as part of Yugoslavia and its descent into ethnic violence in the early 1990s, the thesis critiques the current state of education policies driven by ethnonationalist agendas and the lack of welcoming spaces for minorities. It argues that the education system, instead of acting as a bridge for unity, is now a significant barrier to reconciliation and integration. This thesis explores how this reality came to be institutionalized through the provisions of the Dayton Peace Agreement, enabling an education system where major ethnic groups, through ethnically aligned political parties, have near autonomy over the content they teach children. Through an in-depth analysis of the historical developments and the present challenges of reforming this divisive educational landscape, the study warns of the dangers posed by persistent ethnic divisions in education.

description: The long time behavior of velocity-magnetic field alignment is numerically investigated in the framework of MHD shell model. In the stationary forced case, the correlation parameter C displays a nontrivial behavior with long periods of high variability which alternates with periods of almost constant C. The temporal statistics of correlation is shown to be non Poissonian, and the pdf of constant sign periods displays clear power law tails. The possible relevance of the model for geomagnetic dynamo problem is discussed.

Publisher: name: arXiv
Year: 2018
Subjects: subject: Software Engineering (cs.SE)
subject: FOS: Computer and information sciences

description: Descartes is a tool that implements extreme mutation operators and aims at finding pseudo-tested methods in Java projects. It leverages the efficient transformation and runtime features of PIT. The demonstration compares Descartes with Gregor, the default mutation engine provided by PIT, in a set of real open source projects. It considers the execution time, number of mutants created and the relationship between the mutation scores produced by both engines. It provides some insights on the main features exposed by Descartes.
Symmetry breaking in competing single-well linear-nonlinear potentials

description: The combination of linear and nonlinear potentials, both shaped as a single well, enables competition between the confinement and expulsion induced by the former and latter potentials, respectively. We demonstrate that this setting leads to spontaneous symmetry breaking (SSB) of the ground state in the respective generalized nonlinear Schrödinger (Gross-Pitaevskii) equation, through a spontaneous off-center shift of the trapped mode. Two different SSB bifurcation scenarios are possible, depending on the shape of the nonlinearity-modulation profile, which determines the nonlinear potential. If the profile is bounded (remaining finite at $|x|\rightarrow \infty $), at a critical value of the integral norm the spatially symmetric state loses its stability, giving rise to a pair of mutually symmetric stable asymmetric ones via a direct pitchfork bifurcation. On the other hand, if the nonlinear potential is unbounded, two unstable asymmetric modes merge into the symmetric metastable one and destabilize it, via an inverted pitchfork bifurcation. Parallel to a systematic numerical investigation, basic results are obtained in an analytical form. The settings can be realized in Bose-Einstein condensates and nonlinear optical waveguides.

uGMRT detections of HI 21-cm absorption associated with intermediate redshift galaxies
Creators: name: Aditya, J. N. H. S.
Publisher: name: arXiv
Year: 2018
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: I report detections of four new HI 21-cm absorbers associated with sources at intermediate redshifts, 0.7 < z < 1.0. The sources are part of a sample of 11 radio-loud galaxies, all at 0.7 < z < 1.0, that were searched for associated HI 21-cm absorption using uGMRT. Previously, just four such absorbers were known in the literature at these redshifts; the current observations have increased the total to eight. The results indicate that the detection fraction at intermediate redshifts could be as high as that at lower redshifts, 30\%, on contrary to a much lower detection fraction observed in samples at z > 1. Three detections show strong blueshifted features, indicating cold gas outflows. These three sources also tentatively show excess [O II] line luminosity compared to a bulk of the remaining sample, possibly suggesting that the hosts of these AGNs harbour different environments, either due to interaction with the radio jets or due to excess star formation in the host galaxy. Further, a cold HI mass outflow rate of \approx 78 M_{sun} yr^{-1} , assuming T_s = 1000 K, is estimated for the detection towards SDSS J014652.79-015721.2, at z = 0.95904, which is the highest till date in comparison to similar estimates available in the literature.

Social Justice Aspects of External Education Provision in Chad
Creators: name: Cromer, Gia
Publisher: name: Journal of Mason Graduate Research
Year: 2019

description: This paper addresses considerations for social justice in education through a multi- discipline perspective. By combining theories from education policy, political science, and development, I argue for greater national level involvement in education policy using the context of the Republic of Chad as an example. Based on Chad’s inherited, as well as present, education and government situation, changing the current implementation practices for education development will likely increase long term success in the adoption of new education policies and in building democratic governance capabilities. In addition, this article offers the terms non-economically self-determining countries and economically self- determining countries as useful considerations for policy change and as contributions to the theoretical understanding of education policy development.
