subject: FOS: Physical sciences

description: I propose an expression for the electromagnetic wave impedance of a two-dimensional atomic crystal, and I deduce the Fresnel coefficients in terms of this quantity. It is widely known that a two-dimensional crystal can absorb light, if its conductivity is different from zero. It is less emphasized that they can also store a certain amount of electromagnetic energy. The concept of impedance is useful to quantify this point.

description: We study current correlations in a $T$-junction composed of a grounded topological superconductor and of two normal-metal leads which are biased at a voltage $V$. We show that the existence of an isolated Majorana zero mode in the junction dictates a universal behavior for the cross correlation of the currents through the two normal-metal leads of the junction. The cross correlation is negative and approaches zero at high bias voltages as -1/$V$. This behavior is robust in the presence of disorder and multiple transverse channels, and persists at finite temperatures. In contrast, an accidental low-energy Andreev bound state gives rise to nonuniversal behavior of the cross correlation. We employ numerical transport simulations to corroborate our conclusions.

Information Services Referral

description: This study explored the challenges that traditional, phone-based information and referral (I&R) agencies face in expanding their services over the World Wide Web (Web) medium. Through the use of an online survey, agencies providing Web and phone I&R were asked to compare their levels of service, support, and satisfaction between the two contact methods. Overall, 21 agencies across the nation with diverse service characteristics participated in the survey. From their responses, it was determined that the major challenges facing Web-based I&R was a lack of funding, insufficient evaluation methods and procedures, and inadequate usability for the searching process. Recommendations were presented to overcome these obstacles.
Update on the GRB universal scaling E$_{\rm{X,iso}}$-E$_{\rm{γ,iso}}$-E$_{\rm{pk}}$ with ten years of $Swift$ data

description: From a comprehensive statistical analysis of $Swift$ X-ray light-curves of gamma-ray bursts (GRBs) collected from December 2004 to the end of 2010, we found a three-parameter correlation between the isotropic energy emitted in the rest frame 1-10$^4$ keV energy band during the prompt emission (E$_{\rm{γ,iso}}$), the rest frame peak of the prompt emission energy spectrum (E$_{\rm{pk}}$), and the X-ray energy emitted in the rest frame 0.3-30 keV observed energy band (E$_{\rm{X,iso}}$), computed excluding the contribution of the flares. In this paper, we update this correlation with the data collected until June 2014, expanding the sample size with $\sim$35% more objects, where the number of short GRBs doubled. With this larger sample we confirm the existence of a universal correlation that connects the prompt and afterglow properties of long and short GRBs. We show that this correlation does not depend on the X-ray light-curve morphology and that further analysis is necessary to firmly exclude possible biases derived by redshift measurements. In addition we discuss about the behavior of the peculiar objects as ultra-long GRBs and we propose the existence of an intermediate group between long and short GRBs. Interestingly, two GRBs with uncertain classification fall into this category. Finally, we discuss the physics underlying this correlation, in the contest of the efficiency of conversion of the prompt $γ$-ray emission energy into the kinetic energy of the afterglow, the photosferic model, and the cannonball model.

description: In most works on deep incremental learning research, it is assumed that novel samples are pre-identified for neural network retraining. However, practical deep classifiers often misidentify these samples, leading to erroneous predictions. Such misclassifications can degrade model performance. Techniques like open set recognition offer a means to detect these novel samples, representing a significant area in the machine learning domain. In this paper, we introduce a deep class-incremental learning framework integrated with open set recognition. Our approach refines class-incrementally learned features to adapt them for distance-based open set recognition. Experimental results validate that our method outperforms state-of-the-art incremental learning techniques and exhibits superior performance in open set recognition compared to baseline methods.

description: Angesichts der derzeitigen Impfstoffknappheit geht mit den bundesweiten Schutzimpfungen gegen COVID-19 die Notwendigkeit einer Priorisierung bestimmter Bevölkerungsgruppen einher. Basierend auf den Empfehlungen der STIKO sollen zunächst Personen mit besonders hohem Risiko für schwere oder tödliche COVID-19-Verläufe oder beruflicher Exposition geimpft werden. Diese Empfehlungen stützen sich überwiegend auf internationale Studien - für den deutschen Versorgungskontext steht nur begrenzt Evidenz zur Bedeutung relevanter Risikofaktoren für einen schweren COVID-19-Verlauf zur Verfügung. Das Ziel der im Epidemiologischen Bulletin 19/2021 vorgestellten Studie war es, die Relevanz ausgewählter Vorerkrankungen für einen schweren COVID-19-Verlauf in der in Deutschland lebenden Bevölkerung empirisch zu überprüfen, Erkrankungen hinsichtlich ihres Risikos für einen schweren COVID-19-Verlauf zu ordnen und damit eine einfache, im Versorgungsalltag unkompliziert umsetzbare und dabei möglichst effektive Grundlage für die Impfrangfolge in der ambulanten ärztlichen Versorgung bilden.

description: Although Wikipedia is an extremely popular website and is useful for casual or  preliminary research, the propriety of using Wikipedia for serious research and citing to it  is the subject of fervent debate. In the legal field, this debate rages on in the context of  judicial citation to Wikipedia in court opinions, with the primary focus on whether  Wikipedia should never be cited or if it is an acceptable practice as long as Wikipedia is  used to obtain tangential information only.  This study analyzes judicial citation to Wikipedia in published federal court opinions in  an attempt to determine when and why Wikipedia is cited by federal judges. The results  of this citation analysis were illuminating and at times troubling and surprising. Most  significantly, this study discovered that Wikipedia was used to obtain information  important to the outcome of the case in just over one-third of all opinions.

description: Every year, soybean yields are reduced by numerous diseases, especially the soybean cyst nematode (SCN). Identifying the presence of SCN and measuring its population densities in the field is challenging as there are no visible signs of disease. The only sure way to evaluate SCN population levels is to extract the cysts from the soil, extract the eggs from the cysts, and count them. Currently, this extraction process is typically done in commercial soil analysis laboratories and university plant diagnostic clinics and requires multiple steps. To make this process easier, we have created a robotic instrument that can automate the extraction of nematode cysts from soil and the subsequent release of their eggs. This technology is operated using a touchscreen interface and is tested using soil samples from two farms. The results are comparable to the conventional technique. Our robotic instrument makes SCN soil diagnostics more efficient, aiding in the long-term integrated pest management of this harmful soybean pest.

description: For every Lie pair $(L,A)$ of algebroids we construct a dg-manifold structure on the $\mathbb{Z}$-graded manifold $\mathcal M=L[1]\oplus L/A$ such that the inclusion $ι: A[1] \to \mathcal M$ and the projection $p:\mathcal M\to L[1]$ are morphisms of dg-manifolds. The vertical tangent bundle $T^p\mathcal M$ then inherits a structure of dg-Lie algebroid over $\mathcal M$. When the Lie pair comes from a matched pair of Lie algebroids, we show that the inclusion $ι$ induces a quasi-isomorphism that sends the Atiyah class of this dg-Lie algebroid to the Atiyah class of the Lie pair. We also show how (Atiyah classes of) Lie pairs and dg-Lie algebroids give rise to (Atiyah classes of) dDG-algebras.

description: Meta-evaluation studies of system performances in controlled offline evaluation campaigns, like TREC and CLEF, show a need for innovation in evaluating IR-systems. The field of academic search is no exception to this. This might be related to the fact that relevance in academic search is multilayered and therefore the aspect of user-centric evaluation is becoming more and more important. The Living Labs for Academic Search (LiLAS) lab aims to strengthen the concept of user-centric living labs for the domain of academic search by allowing participants to evaluate their retrieval approaches in two real-world academic search systems from the life sciences and the social sciences. To this end, we provide participants with metadata on the systems' content as well as candidate lists with the task to rank the most relevant candidate to the top. Using the STELLA-infrastructure, we allow participants to easily integrate their approaches into the real-world systems and provide the possibility to compare different approaches at the same time.

description: Hyperspectral unmixing allows representing mixed pixels as a set of pure materials weighted by their abundances. Spectral features alone are often insufficient, so it is common to rely on other features of the scene. Matrix models become insufficient when the hyperspectral image (HSI) is represented as a high-order tensor with additional features in a multimodal, multifeature framework. Tensor models such as canonical polyadic decomposition allow for this kind of unmixing but lack a general framework and interpretability of the results. In this article, we propose an interpretable methodological framework for low-rank multifeature hyperspectral unmixing based on tensor decomposition (MultiHU-TD) that incorporates the abundance sum-to-one constraint in the alternating optimization alternating direction method of multipliers (ADMM) algorithm and provide in-depth mathematical, physical, and graphical interpretation and connections with the extended linear mixing model. As additional features, we propose to incorporate mathematical morphology and reframe a previous work on neighborhood patches within MultiHU-TD. Experiments on real HSIs showcase the interpretability of the model and the analysis of the results. Python and MATLAB implementations are made available on GitHub.

description: The jamming and percolation for two generalized models of random sequential adsorption (RSA) of linear $k$-mers (particles occupying $k$ adjacent sites) on a square lattice are studied by means of Monte Carlo simulation. The classical random sequential adsorption (RSA) model assumes the absence of overlapping of the new incoming particle with the previously deposited ones. The first model LK$_d$ is a generalized variant of the RSA model for both $k$-mers and a lattice with defects. Some of the occupying $k$ adjacent sites are considered as insulating and some of the lattice sites are occupied by defects (impurities). For this model even a small concentration of defects can inhibit percolation for relatively long $k$-mers. The second model is the cooperative sequential adsorption (CSA) one, where, for each new $k$-mer, only a restricted number of lateral contacts $z$ with previously deposited $k$-mers is allowed. Deposition occurs in the case when $z\leq (1-d)z_m$ where $z_m=2(k+1)$ is the maximum numbers of the contacts of $k$-mer, and $d$ is the fraction of forbidden NN contacts. Percolation is observed only at some interval $k_{min}\leq k\leq k_{max}$ where the values $k_{min}$ and $k_{max}$ depend upon the fraction of forbidden contacts $d$. The value $k_{max}$ decreases as $d$ increases. A logarithmic dependence of the type $\log(k_{max})=a+bd$, where $a=-4.03 \pm 0.22$, $b=4.93 \pm 0.57 $, is obtained.

description: We propose a variational technique to optimize for generalized barycentric coordinates that offers additional control compared to existing models. Prior work represents barycentric coordinates using meshes or closed-form formulae, in practice limiting the choice of objective function. In contrast, we directly parameterize the continuous function that maps any coordinate in a polytope's interior to its barycentric coordinates using a neural field. This formulation is enabled by our theoretical characterization of barycentric coordinates, which allows us to construct neural fields that parameterize the entire function class of valid coordinates. We demonstrate the flexibility of our model using a variety of objective functions, including multiple smoothness and deformation-aware energies; as a side contribution, we also present mathematically-justified means of measuring and minimizing objectives like total variation on discontinuous neural fields. We offer a practical acceleration strategy, present a thorough validation of our algorithm, and demonstrate several applications.

description: This paper presents findings from a study that explored obstacles undergraduate students  who are novice users of archives face when using online finding aids, and to what extent  these barriers negatively impact their ability to use finding aids to access primary source  materials. A usability study of four different finding aids was conducted with eight  undergraduate students from the University of North Carolina at Chapel Hill. The study  participants completed a set of tasks with the finding aids in individual sessions, which  were recorded. Then participants were asked while reviewing their recording in a  stimulated recall session to describe any characteristics of the finding aids that posed a  particular challenge or that made using them easier. Although participants faced barriers,  particularly in the language, organization, and visual presentation of finding aids, as a  whole the subjects performed well and were able to answer most of the questions in a  reasonable amount of time. Two factors that helped the novice users use the finding aids  were reliance on general computer and web navigation skills and taking the time to learn  about the organization and structure of the finding aids.

Automatic Keyphrases Extraction
Controlled vocabularies

description: The demand for high quality metadata is growing in response to the massive growth of digital information and data. Traditionally, keywords and other metadata have been created by authors and professional indexers. However, manual metadata generation is increasingly insufficient, due to the digital information explosion and the growth of multidisciplinary digital environments. There is a growing need to develop, study, and advance knowledge about tools that automatically generate metadata, particularly tools that reach across different disciplines. This study addresses this need by introducing "HIVE" which supports automatic metadata generation by drawing descriptors from multiple SKOS (Simple Knowledge Organization Systems) encoded controlled vocabularies. First, HIVE's core components and key concepts are defined and discussed. Next, this study describes the step-by-step process of adding new controlled vocabularies into the HIVE demo at RENCI.org. The paper concludes by showing the result of the step-by-step process and addressing further steps of the HIVE project.

description: The layered honeycomb magnet alpha-RuCl3 has been proposed as a candidate to realize a Kitaev spin model with strongly frustrated, bond-dependent, anisotropic interactions between spin-orbit entangled jeff=1/2 Ru4+ magnetic moments. Here we report a detailed study of the three-dimensional crystal structure using x-ray diffraction on untwinned crystals combined with structural relaxation calculations. We consider several models for the stacking of honeycomb layers and find evidence for a crystal structure with a monoclinic unit cell corresponding to a stacking of layers with a unidirectional in-plane offset, with occasional in-plane sliding stacking faults, in contrast with the currently-assumed trigonal 3-layer stacking periodicity. We report electronic band structure calculations for the monoclinic structure, which find support for the applicability of the jeff=1/2 picture once spin orbit coupling and electron correlations are included. We propose that differences in the magnitude of anisotropic exchange along symmetry inequivalent bonds in the monoclinic cell could provide a natural mechanism to explain the spin gap observed in powder inelastic neutron scattering, in contrast to spin models based on the three-fold symmetric trigonal structure, which predict a gapless spectrum within linear spin wave theory. Our susceptibility measurements on both powders and stacked crystals, as well as neutron powder diffraction show a single magnetic transition at TN ~ 13K. The analysis of the neutron data provides evidence for zigzag magnetic order in the honeycomb layers with an antiferromagnetic stacking between layers. Magnetization measurements on stacked single crystals in pulsed field up to 60T show a single transition around 8T for in-plane fields followed by a gradual, asymptotic approach to magnetization saturation, as characteristic of strongly anisotropic exchange interactions.

description: Due to the computational complexity of 3D medical image segmentation, training with downsampled images is a common remedy for out-of-memory errors in deep learning. Nevertheless, as standard spatial convolution is sensitive to variations in image resolution, the accuracy of a convolutional neural network trained with downsampled images can be suboptimal when applied on the original resolution. To address this limitation, we introduce FNOSeg3D, a 3D segmentation model robust to training image resolution based on the Fourier neural operator (FNO). The FNO is a deep learning framework for learning mappings between functions in partial differential equations, which has the appealing properties of zero-shot super-resolution and global receptive field. We improve the FNO by reducing its parameter requirement and enhancing its learning capability through residual connections and deep supervision, and these result in our FNOSeg3D model which is parameter efficient and resolution robust. When tested on the BraTS'19 dataset, it achieved superior robustness to training image resolution than other tested models with less than 1% of their model parameters.

description: We investigate the prospects of creating broad rotational wave packets by means of molecular interaction with long sequences of intense femtosecond pulses. Using state-resolved rotational Raman spectroscopy of oxygen, subject to a sequence of more than 20 laser pulses with peak intensities exceeding $10^{13}$ W/cm$^{2}$ per pulse, we show that the centrifugal distortion is the main obstacle on the way to reaching high rotational states. We demonstrate that the timing of the pulses can be optimized to partially mitigate the centrifugal limit. The cumulative effect of a long pulse sequence results in high degree of rotational coherence, which is shown to cause an efficient spectral broadening of probe light via cascaded Raman transitions.

description: This study describes an analysis of information provided on writing center and library collaboration projects at Association of Research Library (ARL) institutions. The study was conducted to determine the frequency of mutually linking organizations, the frequency of collocation, and visibility of collaboration projects on the Web. By examining the 111 writing center and library websites, evidence of some type of collaboration was found in half of the sample. One-third of the institutions had mutually linking organizations and over one-third were either collocated, or the writing center used space in the library for additional tutoring services.

description: We use a Green's function approach in order to develop a method for calculating the tunneling rate between radiatively-generated non-degenerate vacua. We apply this to a model that exhibits spontaneous symmetry breaking via the Coleman-Weinberg mechanism, where we determine the self-consistent tunneling configuration and illustrate the impact of gradient effects that arise from accounting for the underlying space-time inhomogeneity.

Anomalous Dimension of the Electrical Current in the Normal State of the Cuprates from the Fractional Aharonov-Bohm Effect

description: We demonstrate quite generally how a conserved current can have an anomalous dimension. We show here that if the current in the normal state of the cuprates has an anomalous dimension, then the Aharonov-Bohm flux through a ring does not have the standard $eBA/\hbar$ form, where $A$ is the area and $B$ the external magnetic field, but instead is modified by a geometrical factor that depends directly on the anomalous dimension of the current. We calculate the signal in square and disk geometries. In both cases, the deviation from the standard result is striking and offers a fingerprint about what precisely is strange about the strange metal.

description: Theorie und Praxis der Partizipation stehen in sehr unterschiedlichen Traditionen und Diskussionszusammenhängen. Die Frage, was unter Partizipation zu verstehen ist, wird je nach historischer Phase, gesellschaftlichem Bereich, Politikfeld und Zielstellung unterschiedlich beantwortet; dabei spielen zeitgenössische gesellschaftspolitische Entwicklungen eine große Rolle. Es ist daher nicht verwunderlich, dass sich Inhalte und Formen von Partizipation auch im Kontext der Umweltdebatte über die Jahrzehnte verändert haben - und weiterhin verändern werden, sollen sie den Herausforderungen der Zukunft gerecht werden.

description: Here, we report the observation of electron transfer mediated decay (ETMD) involving Mg clusters embedded in helium nanodroplets which is initiated by the ionization of helium followed by removal of two electrons from the Mg clusters of which one is transferred to the He environment neutralizing it while the other electron is emitted into the continuum. The process is shown to be the dominant ionization mechanism for embedded clusters for photon energies above the ionization potential of He. The photoelectron spectrum reveals a low energy ETMD peak. For Mg clusters larger than 5 atoms we observe stable doubly-ionized clusters. We argue that ETMD provides a new pathway to the formation of doubly-ionized cold species.

description: Online outreach efforts are increasingly important to the relevance of digital library and archives collections; such efforts have great potential to create new audiences for these collections and encourage users to engage with digital content. However, these online outreach activities are frequently under-appreciated and currently under-studied. By considering the background of online outreach, past and present attitudes towards outreach, definitions of outreach itself, methods for measuring the success of outreach programs, and finally examining and evaluating the online outreach activities of the recent Triangle Research Library Network "Content, Context, and Capacity" project, this paper hopes to further the understanding of and enthusiasm for online outreach as a valuable resource for the archives community.
Trustworthy Formal Natural Language Specifications

description: Interactive proof assistants are computer programs carefully constructed to check a human-designed proof of a mathematical claim with high confidence in the implementation. However, this only validates truth of a formal claim, which may have been mistranslated from a claim made in natural language. This is especially problematic when using proof assistants to formally verify the correctness of software with respect to a natural language specification. The translation from informal to formal remains a challenging, time-consuming process that is difficult to audit for correctness. This paper shows that it is possible to build support for specifications written in expressive subsets of natural language, within existing proof assistants, consistent with the principles used to establish trust and auditability in proof assistants themselves. We implement a means to provide specifications in a modularly extensible formal subset of English, and have them automatically translated into formal claims, entirely within the Lean proof assistant. Our approach is extensible (placing no permanent restrictions on grammatical structure), modular (allowing information about new words to be distributed alongside libraries), and produces proof certificates explaining how each word was interpreted and how the sentence's structure was used to compute the meaning. We apply our prototype to the translation of various English descriptions of formal specifications from a popular textbook into Lean formalizations; all can be translated correctly with a modest lexicon with only minor modifications related to lexicon size.
