description: We show that interlayer charge transfer in 2D materials can be driven by an in-plane electric field, giving rise to electrical multipole generation in linear and second order of in-plane field. The linear and nonlinear effects have quantum geometric origins in the Berry curvature and quantum metric respectively, defined in extended parameter spaces characteristic of layered materials. We elucidate their symmetry characters, and demonstrate sizable dipole and quadrupole polarizations respectively in twisted bilayers and trilayers of transition metal dichalcogenides. Furthermore, we show that the effect is strongly enhanced during the topological phase transition tuned by interlayer translation. The effects point to a new electric control on layer quantum degree of freedom.

description: We present Q-Seg, a novel unsupervised image segmentation method based on quantum annealing, tailored for existing quantum hardware. We formulate the pixel-wise segmentation problem, which assimilates spectral and spatial information of the image, as a graph-cut optimization task. Our method efficiently leverages the interconnected qubit topology of the D-Wave Advantage device, offering superior scalability over existing quantum approaches and outperforming several tested state-of-the-art classical methods. Empirical evaluations on synthetic datasets have shown that Q-Seg has better runtime performance than the state-of-the-art classical optimizer Gurobi. The method has also been tested on earth observation image segmentation, a critical area with noisy and unreliable annotations. In the era of noisy intermediate-scale quantum, Q-Seg emerges as a reliable contender for real-world applications in comparison to advanced techniques like Segment Anything. Consequently, Q-Seg offers a promising solution using available quantum hardware, especially in situations constrained by limited labeled data and the need for efficient computational runtime.

User Surveys

description: This paper examines current practices for creating user profiles for archive patrons and their information needs at the Manuscripts Department at the University of North Carolina at Chapel Hill. Archivists know their users informally and individually, but do not know the characteristics of the user community as a whole because they have no systematic tool for measuring this. Archivists cannot develop effective access and outreach programs because they have no empirical data to support their efforts. Inspired primarily by the work of Paul Conway, this study presents a comprehensive system to gather user information. The proposed system that emerged from the study utilizes and enhances current reference practices in order to gather data on patrons and their information needs. This includes the ever-growing demands of remote reference. The proposed system stands as a model for analysis and sharing of user information needs and use behavior between repositories of all sizes.

description: In this paper we study the time evolution of (Renyi) entanglement entropies for locally excited states in four dimensional free massless fermionic field theory. Locally excited states are defined by being acted by various local operators on the ground state. Their excesses are defined by subtracting (Renyi) entanglement entropy for the ground state from those for locally excited states. They finally approach some constant if the subsystem is given by half of the total space. They have spin dependence. They can be interpreted in terms of quasi-particles.

description: The two-dimensional Dirac operator describes low-energy excitations in graphene. Different choices for the boundary conditions give rise to qualitative differences in the spectrum of the resulting operator. For a family of boundary conditions, we find a lower bound to the spectral gap around zero, proportional to $|Ω|^{-1/2}$, where $Ω\subset \mathbb{R}^2$ is the bounded region where the Dirac operator acts. This family contains the so-called infinite mass and armchair cases used in the physics literature for the description of graphene quantum dots.

description: This study examines the promotion of a service in one academic library. This library had lower than expected attendance in a citation management instruction class. The purpose of the study was to determine if placement of flyers in convenient locations would increase attendance at the advertised library service. Although the results of the study did not support the original expectation, from a follow-up study, it was concluded that information encountering was a useful framework for determining appropriate locations for flyer placement. Findings indicate that multiple formats of promotional materials are most effective because they increase the likelihood of exposure to the promotional message. Additionally, an understanding of user needs and motivation can help librarians devise a message that will impact the user.

description: We compute the new supersymmetric index of a large class of N=2 heterotic compactifications with torsion, corresponding to principal two-torus bundles over warped K3 surfaces with H-flux. Starting from a UV description as a (0,2) gauged linear sigma-model with torsion, we use supersymmetric localization techniques to provide an explicit expression of the index as a sum over the Jeffrey-Kirwan residues of the one-loop determinant. We finally propose a geometrical formula that gives the new supersymmetric index in terms of bundle data, regardless of any particular choice of underlying two-dimensional theory.

description: This study employs a functional perspective in assessing the motives of volunteers for volunteering in public libraries. A 30-item survey instrument, the Volunteer Functions Inventory (VFI), was completed by 28 volunteers at three branches of the Wake County Public Library system to determine whether motivations varied according to age. Although the intent of the study was to compare three age groups of volunteers (under 20 years old, 20 to 55 years old, and over 55 years old), too few surveys were returned to allow such a comparison. The most surveys were returned from the oldest age group and results from this group are consistent with past research in that older volunteers tended to be motivated heavily by their values and far less so by career concerns. Suggestions for improving future research with public library volunteers are given along with information on how to improve volunteer outreach and recruitment.

Seven community-based archival research initiatives  were chosen and examined, including: Historically Black Towns and Settlements Alliance, Documenting Ferguson, D.C Africaana Archives Project, Black Metropolis Research Consortium, Institutional Archives on Women and Architecture, Eighth Air Force Archive, and the Saints at War Project. Interviews with the professionals at these initiatives helped the researcher to identify perceptions regarding how the partnerships form, the activities performed by each of the participants, how materials were collected and maintained, and the long-term sustainability of these efforts. This research has numerous implications for the archival profession, including both benefits and barriers to collaboration. Archivists at other institutions can look to this research when attempting to democratize collecting practices and develop lasting partnerships with surrounding communities.

description: A finite dimensional quantum system for which the quantum chaos conjecture applies has eigenstates, which show the same statistical properties than the column vectors of random orthogonal or unitary matrices. Here, we consider the different probabilities for obtaining a specific outcome in a projective measurement, provided the system is in one of its eigenstates. We then give analytic expressions for the joint probability density for these probabilities, with respect to the ensemble of random matrices. In the case of the unitary group, our results can be applied, also, to the phenomenon of universal conductance fluctuations, where the same mathematical quantities describe partial conductances in a two-terminal mesoscopic scattering problem with a finite number of modes in each terminal.

description: We investigated the optical properties of single crystals of one-dimensional telluride Ta4SiTe4, which shows high thermoelectric performance below room temperature. Optical conductivity estimated from reflectivity spectra indicates the presence of a small energy gap of 0.1-0.15 eV at the Fermi energy. At the lowest energy, optical conductivity along the Ta4SiTe4 chain is an order of magnitude higher than that perpendicular to this direction, reflecting the anisotropic electron conduction in Ta4SiTe4. These results indicate that coexistence of a very small band gap and anisotropic electron conduction is a promising strategy to develop a high-performance thermoelectric material for low temperature applications.

description: Biblionet is a five-year grant from the Gates Foundation for the development of the  Romanian library system. The grant provides computers and training to public libraries,  and has a subgrant competition called the Community Participation Contest (CPC) that  allows librarians to apply for up to $2500 in funding to use technology in a new  community program. A descriptive case study was conducted to study the ways that four  iterations of the Community Participation Contest have operated in rural, suburban and  urban environments. The field of Community Informatics and Diffusion of Innovation  theory informed the analysis of how librarians and library users think about the library  and the CPC. The participatory design of the grant process allowed the programs to be  tailored to the needs of the community, and it was perceived as a successful innovation in  library services.

description: We present a method to identify Ultra Faint Dwarf Galaxy (UFDG) candidates in the halo of the Milky Way using the future Gaia catalogue and we explore its detection limits and completeness. The method is based on the Wavelet Transform and searches for over-densities in the combined space of sky coordinates and proper motions, using kinematics in the search for the first time. We test the method with a Gaia mock catalogue that has the Gaia Universe Model Snapshot (GUMS) as a background, and use a library of around 30 000 UFDGs simulated as Plummer spheres with a single stellar population. For the UFDGs we use a wide range of structural and orbital parameters that go beyond the range spanned by real systems, where some UFDGs may remain undetected. We characterize the detection limits as function of the number of observable stars by Gaia in the UFDGs with respect to that of the background and their apparent sizes in the sky and proper motion planes. We find that the addition of proper motions in the search improves considerably the detections compared to a photometric survey at the same magnitude limit. Our experiments suggest that Gaia will be able to detect UFDGs that are similar to some of the known UFDGs even if the limit of Gaia is around 2 magnitudes brighter than that of SDSS, with the advantage of having a full-sky catalogue. We also see that Gaia could even find some UFDGs that have lower surface brightness than the SDSS limit.

description: Since Mark A. Greene and Dennis Meissner introduced the idea of "More Product Less
Process" (MPLP), there appears to have been a shift to "light" processing in various types
of archival institutions. Since 2005 the literature discussing this idea has focused on
differing opinions of archivists and whether they use MPLP. Many institutions have
quoted and clearly expressed their acceptance of MPLP within their processing
procedures. However, there is a clear line between organizations that have accepted and
denied the use of the idea. This study examines whether MPLP is actually a recent
change that occurred within the last decade or an ideal part of processing within archival
institutions for several years.

description: We present a self-gravitating, analytic and globally regular Skyrmion solution of the Einstein-Skyrme system with winding number w = 1, in presence of a cosmological constant. The static spacetime metric is the direct product RxS3 and the Skyrmion is the self-gravitating generalization of the static hedgehog solution of Manton and Ruback with unit topological charge. This solution can be promoted to a dynamical one in which the spacetime is a cosmology of the Bianchi type-IX with time-dependent scale and squashing coefficients. Remarkably, the Skyrme equations are still identically satisfied for all values of these parameters. Thus, the complete set of field equations for the Einstein-Skyrme-Lambda system in the topological sector reduces to a pair of coupled, autonomous, nonlinear differential equations for the scale factor and a squashing coefficient. These equations admit analytic bouncing cosmological solutions in which the universe contracts to a minimum non-vanishing size, and then expands. A non-trivial byproduct of this solution is that a minor modification of the construction gives rise to a family of stationary, regular configurations in General Relativity with negative cosmological constant supported by an SU(2) nonlinear sigma model. These solutions represent traversable AdS wormholes with NUT parameter in which the only "exotic matter" required for their construction is a negative cosmological constant.

A Choice-Driven Service Network Design and Pricing Including Heterogeneous Behaviors

description: The design and pricing of services are two of the most important decisions faced by any intermodal transport operator. The key success factor lies in the ability of meeting the needs of the shippers. Therefore, making full use of the available information about the demand helps to come up with good design and pricing decisions. With this in mind, we propose a Choice-Driven approach, incorporating advanced choice models directly into a Service Network Design and Pricing problem. We evaluate this approach considering three different mode choice models: one deterministic with 4 attributes (cost, time, frequency and accessibility); and two stochastic also accounting for unobserved attributes and shippers heterogeneity respectively. To reduce the computational time for the stochastic instances, we propose a predetermination heuristic. These models are compared to a benchmark, where shippers are solely cost-minimizers. Results show that the operator profits can be significantly improved, even with the deterministic version. The two stochastic versions further increase the realized profits, but considering heterogeneity allows a better estimation of the demand.

young adult publishing, but the difference is not significant enough to support such
claims.

description: Entanglement in quantum many-body systems can exhibit universal phenomena governed by long-distance properties. We study universality and phase transitions of the entanglement inherent to open many-body systems, namely, the entanglement between a system of interest and its environment. Specifically, we consider the Tomonaga-Luttinger liquid (TLL) under a local measurement and analyze its unconditioned nonunitary evolution, where the measurement outcomes are averaged over. We quantify the system-environment entanglement by the Rényi entropy of the post-measurement density matrix, whose size-independent term encodes the universal low-energy physics. We develop a field-theoretical description to relate the universal term to the effective ground-state degeneracy known as the $g$ function in a boundary conformal field theory, and use the renormalization group method to determine its value. We show that the universal contribution is determined by the TLL parameter $K$ and can exhibit singularity signifying an entanglement phase transition. Surprisingly, in certain cases the size-independent contribution can increase as a function of the measurement strength in contrast to what is naïvely expected from the $g$-theorem. We argue that this unconventional behavior could be attributed to the dangerously irrelevant term which has been found in studies of the resistively shunted Josephson junction. We also check these results by numerical calculations in the spin-$\frac{1}{2}$ XXZ chain subject to a site-resolved measurement. Possible experimental realization in ultracold gases, which requires no postselections, is discussed.

On indication, strict monotonicity, and efficiency of projections in a general class of path-based data envelopment models

description: Data envelopment analysis (DEA) theory formulates a number of desirable properties that DEA models should satisfy. Among these, indication, strict monotonicity, and strong efficiency of projections tend to be grouped together in the sense that, in individual models, typically, either all three are satisfied or all three fail at the same time. Specifically, in slacks-based graph models, the three properties are always met; in path-based models, such as radial models, directional distance function models, and the hyperbolic function model, the three properties, with some minor exceptions, typically all fail.
 Motivated by this observation, the article examines relationships among indication, strict monotonicity, and strong efficiency of projections in the class of path-based models over variable returns-to-scale technology sets. Under mild assumptions, it is shown that the property of strict monotonicity and strong efficiency of projections are equivalent, and that both properties imply indication. This paper also characterises a narrow class of technology sets and path directions for which the three properties hold in path-based models.

(Eds.), Proceedings of the 25th Annual Conference on Research in Undergraduate Mathematics Education (pp. 306-314). Mathematical Association of America.Abstract: In-person tutorials present a prime opportunity for students to work with others to engage theirproblem-solving and critical-thinking skills. We investigate the use of interactive tutorials in alarge, second-year service mathematics course as part of a quasi-experiment whereby studentscould either attend in-person tutorials (for a participation mark) or complete the tutorialsindividually without attending the live sessions and submit solutions for credit. Our analyses ofstudent data and self-efficacy measures suggest that consistent attendance at in-person tutorialsmay maintain and improve students’ self-efficacy. Median changes to self-efficacy measures forstudents who attended in-person tutorials were higher than those who completed tutorialsindividually without attending the live sessions. The difference between the changes to theEmotional Regulation aspect of tutorial self-efficacy was statistically significant (p = .031),highlighting the role in-person tutorials play in supporting students’ mathematical learningbeyond academic outcomes.

description: We present GausSN, a Bayesian semi-parametric Gaussian Process (GP) model for time-delay estimation with resolved systems of gravitationally lensed supernovae (glSNe). GausSN models the underlying light curve non-parametrically using a GP. Without assuming a template light curve for each SN type, GausSN fits for the time delays of all images using data in any number of wavelength filters simultaneously. We also introduce a novel time-varying magnification model to capture the effects of microlensing alongside time-delay estimation. In this analysis, we model the time-varying relative magnification as a sigmoid function, as well as a constant for comparison to existing time-delay estimation approaches. We demonstrate that GausSN provides robust time-delay estimates for simulations of glSNe from the Nancy Grace Roman Space Telescope and the Vera C. Rubin Observatory's Legacy Survey of Space and Time (Rubin-LSST). We find that up to 43.6% of time-delay estimates from Roman and 52.9% from Rubin-LSST have fractional errors of less than 5%. We then apply GausSN to SN Refsdal and find the time delay for the fifth image is consistent with the original analysis, regardless of microlensing treatment. Therefore, GausSN maintains the level of precision and accuracy achieved by existing time-delay extraction methods with fewer assumptions about the underlying shape of the light curve than template-based approaches, while incorporating microlensing into the statistical error budget. GausSN is scalable for time-delay cosmography analyses given current projections of glSNe discovery rates from Rubin-LSST and Roman.

description: Precise measurement of magnetic fields is essential for various applications, such as fundamental physics, space exploration, and biophysics. Although recent progress in quantum engineering has assisted in creating advanced quantum magnetometers, there are still ongoing challenges in improving their efficiency and noise resistance. This study focuses on using symmetric graph state resources for quantum magnetometry to enhance measurement precision by analyzing the estimation theory under time-homogeneous and time-inhomogeneous noise models. The results show a significant improvement in estimating both single and multiple Larmor frequencies. In single Larmor frequency estimation, the quantum Fisher information spans a spectrum from the standard quantum limit to the Heisenberg limit within a periodic range of the Larmor frequency, and in the case of multiple Larmor frequencies, it can exceed the standard quantum limit for both noisy cases. This study highlights the potential of graph state-based methods for improving magnetic field measurements under noisy environments.

description: With a great ability to solve regression problems, the artificial neural network has become a powerful tool to facilitate advancing ultrafast laser research. In this contribution, we demonstrate the capability of a feed-forward neural network (FNN) to predict the output parameters of a mode-locked fiber laser, which mutually depend on multiple intracavity parameters, with high speed and accuracy. A direct mapping between cavity parameters and laser output is realized through the FNN-trained models, bypassing tedious iterative numerical simulation as a common approach to get a converged solution for a laser cavity. We show that the laser output spectrum and temporal pulse profiles can be accurately predicted with the normalized root mean square error (NRMSE) of less than 0.032 within only a 5 ms time frame for scenarios inside and outside the training data. We investigate the influence of FNN configuration on prediction performance. Both gain and spectral filter parameters are explored to test the prediction capability of the trained FNN models at high speed. Straightforward and fast prediction of the laser output performance for varying laser intracavity parameters paves the way to intelligent short-pulsed lasers with inversed design or autonomous operation maintenance.

description: It is remarkable that Heisenberg's position-momentum uncertainty relation leads to the existence of a maximal acceleration for a physical particle in the context of a geometric reformulation of quantum mechanics. It is also known that the maximal acceleration of a quantum particle is related to the magnitude of the speed of transportation in projective Hilbert space. In this paper, inspired by the study of geometric aspects of quantum evolution by means of the notions of curvature and torsion, we derive an upper bound for the rate of change of the speed of transportation in an arbitrary finite-dimensional projective Hilbert space. The evolution of the physical system being in a pure quantum state is assumed to be governed by an arbitrary time-varying Hermitian Hamiltonian operator. Our derivation, in analogy to the inequalities obtained by L. D. Landau in the theory of fluctuations by means of general commutation relations of quantum-mechanical origin, relies upon a generalization of Heisenberg's uncertainty relation. We show that the acceleration squared of a quantum evolution in projective space is upper bounded by the variance of the temporal rate of change of the Hamiltonian operator. Moreover, focusing for illustrative purposes on the lower-dimensional case of a single spin qubit immersed in an arbitrarily time-varying magnetic field, we discuss the optimal geometric configuration of the magnetic field that yields maximal acceleration along with vanishing curvature and unit geodesic efficiency in projective Hilbert space. Finally, we comment on the consequences that our upper bound imposes on the limit at which one can perform fast manipulations of quantum systems to mitigate dissipative effects and/or obtain a target state in a shorter time.

description: O tumor odontogênico adenomatóide (TOA) é uma neoplasia benigna originada do epitélio odontogênico que ocorre, predominantemente, na segunda década de vida, na região anterior da maxila, e com predileção pelo gênero feminino (1,2). O exame histopatológico é elementar para confirmação e conduta de tratamento dessa lesão, uma vez que o seu aspecto benigno prever abordagens mais conservadores (3,4), e dispensa cirurgias mutiladoras. O objetivo deste trabalho é relatar um caso de tratamento de TOA em região anterior de mandíbula. Paciente AADSA, 12 anos, sexo masculino, compareceu ao Serviço de Cirurgia e Traumatologia do Hospital Universitário João de Barros Barreto, queixando-se de um nódulo no queixo. Ao exame clínico, observou-se aumento de volume em região anterior de mandíbula à direita, de consistência firme e indolor à palpação com evolução de aproximadamente 1 ano. O exame radiográfico da região revelou área radiolúcida unilocular circunscrita, e presença de calcificações difusas no interior associada ao dente 43 incluso, além do deslocamento radicular dos dentes adjacentes. Foi realizado biopsia incisional, por meio da qual foi confirmado o diagnóstico de TOA. Realizou-se a marsupialização da lesão durante 20 meses, e constatou-se sua redução progressiva. O paciente foi submetido a cirurgia sob anestesia geral para excisão completa do tumor. No pós-operatório, o paciente evoluiu com deiscência da ferida operatória e drenagem de secreção purulenta. Foi realizado irrigação e sutura do acesso cirúrgico, prescreveu-se amoxilina 500mg e bochechos de clorexidina a 0,12%, e orientado acerca dos cuidados gerais. Atualmente, o paciente encontra-se em acompanhamento pós-operatório. Conclui-se, portanto, que o exame histopatológico é obrigatório para evitar cirurgias mutiladoras desnecessárias, e a marsupialização pode ser utilizada como estratégia inicial eficaz para a redução da lesão, preservação de estrutura óssea adjacente e menor morbidade cirurgia.

description: Recent studies suggest that dark matter (DM) spikes around intermediate-mass black holes could cause observable dephasing in gravitational wave (GW) signals from Intermediate Mass Ratio Inspirals (IMRIs). Previous research primarily used non-self-consistent analytic methods to estimate the impact of DM spikes on eccentric IMRIs. Our study provides the first self-consistent treatment of this phenomenon using $N$-body simulations, incorporating Post-Newtonian effects up to the 2.5 order for accurate and robust results. Contrary to prior works, which posited that the cumulative effect of two-body encounters (dynamical friction; DF) is the primary mechanism for energy dissipation, we reveal that a three-body effect (slingshot mechanism) plays a more significant role in driving the binary system's energy loss and consequent orbital shrinkage. We find that binaries counter-rotating with respect to the DM spike merge faster, while co-rotating binaries merge slower, contrary to expectations from the DF theory. Using Fokker-Planck methods, we also assess the presence and detectability of spikes in realistic environments. When interacting with surrounding materials, DM spikes can have shallower slopes and lower densities than previously considered, leading to smaller signals and lower detection prospects via dephasing. Our results suggest that `deshifting' rather than dephasing might be a more optimistic signature, as it is more robust even in low-density environments.
