description: Symmetries and quantum anomalies serve as powerful tools for constraining complicated quantum many-body systems, offering valuable insights into low-energy characteristics based on their ultraviolet structure. Nevertheless, their applicability has traditionally been confined to closed quantum systems, rendering them largely unexplored for open quantum systems described by density matrices. In this work, we introduce a novel and experimentally feasible approach to detect quantum anomalies in open systems. Specifically, we claim that, when coupled with an external environment, the mixed 't Hooft anomaly between spin rotation symmetry and lattice translation symmetry gives distinctive characteristics for half-integer and integer spin chains in measurements of $\exp(\rm{i}θS^z_{\rm tot})$ as a function of $θ$. Notably, the half-integer spin chain manifests a topological phenomenon akin to the ``level crossing" observed in closed systems. To substantiate our assertion, we develop a lattice-level spacetime rotation to analyze the aforementioned measurements. Based on the matrix product density operator and transfer matrix formalism, we analytically establish and numerically demonstrate the unavoidable singular behavior of $\exp(\rm{i}θS^z_{\rm tot})$ for half-integer spin chains. Conceptually, our work demonstrates a way to discuss notions like ``spectral flow'' and ``flux threading'' in open systems not necessarily with a Hamiltonian.

description: We introduce a direct (Seebeck) and inverse (Peltier) thermoelectric effect induced by electron tunneling between closely separated conducting films. When a transverse temperature gradient is applied along one of two films, a bias voltage is induced in the second thanks to the heat transfer mediated by electrons tunneling through the separation gap. We highlight a non trivial behavior for this Seebeck effect with respect to geometric characteristics of interacting films. Conversely, when an electric current passes through one of two films a strong thermal power can be removed from or inserted in the second film through an induced Peltier effect. In particular we highlight conditions where the induced Seebeck and Peltier coefficients are larger than in the bulk. These induced thermoelectric effects could find broad applications in the fields of energy conversion and cooling at nanoscale.

description: The electrical conductivity of solvent and electrolyte-wetted poly(pyrrole) films is measured, both statically and dynamically, as a function of the potential applied to an electrode in contact with the film. The applied potential determines the film cxidation state. Poly(pyrrole) electrical conductivity is ohmic and indeendent of potential from 0 to +0.4V vs. SSCE, and decreases and becomes less ohmic at more negative potentials. Measurements of the chemically reactive charge stored in poly(pyrrole) as a function of potential were combined with the electrical conductivity results to yield a profile of electrical conductivity vs. average darge per monamer site in the polymer. Electrical conductivity is independent of monomer charge above about 0.15 holes/monomer unit.

description: We study a higher order parabolic partial differential equation that arises in the context of condensed matter physics. It is a fourth order semilinear equation whose nonlinearity is the determinant of the Hessian matrix of the solution. We consider this model in a bounded domain of the real plane and study its stationary solutions both when the geometry of this domain is arbitrary and when it is the unit ball and the solution is radially symmetric. We also consider the initial-boundary value problem for the full parabolic equation. We summarize our results on existence of solutions in these cases and propose an open problem related to the existence of self-similar solutions.

description: The variety of performance measures available for information retrieval systems, search engines, and network filtering agents can be confusing to both practitioners and scholars. Most discussions about these measures address their theoretical foundations and the characteristics of a measure that make it desirable for a particular application. In this work, we consider how preferences exhibited by measures of performance at two points in a search may be formally compared. Criteria are developed that allow one to determine the percent of time or conditions under which two different performance measures suggest that one document ordering is superior to another ordering, or when the two measures disagree about the relative value of document orderings. As an example, graphs provide illustrations of the relationships between precision and F

description: The so called quantum spin Hall phase is a topologically non trivial insulating phase that is predicted to appear in graphene and graphene-like systems. In this work we address the question of whether this topological property persists in multilayered systems. We consider two situations: purely multilayer graphene and heterostructures where graphene is encapsulated by trivial insulators with a strong spin-orbit coupling. We use a four orbital tight-binding model that includes the full atomic spin-orbit coupling and we calculate the $Z_{2}$ topological invariant of the bulk states as well as the edge states of semi-infinite crystals with armchair termination. For homogeneous multilayers we find that even when the spin-orbit interaction opens a gap for all the possible stackings, only those with odd number of layers host gapless edge states while those with even number of layers are trivial insulators. For the heterostructures where graphene is encapsulated by trivial insulators, it turns out that the interlayer coupling is able to induce a topological gap whose size is controlled by the spin-orbit coupling of the encapsulating materials, indicating that the quantum spin Hall phase can be induced by proximity to trivial insulators.

description: We discuss how recent advances in observations, theory and numerical simulations have allowed the stellar community to progress in its understanding of stellar convection, rotation and magnetism and to assess the degree to which the Sun and other stars share similar dynamical properties. Ensemble asteroseismology has become a reality with the advent of large time domain studies, especially from space missions. This new capability has provided improved constraints on stellar rotation and activity, over and above that obtained via traditional techniques such as spectropolarimetry or CaII H&K observations. New data and surveys covering large mass and age ranges have provided a wide parameter space to confront theories of stellar magnetism. These new empirical databases are complemented by theoretical advances and improved multi-D simulations of stellar dynamos. We trace these pathways through which a lucid and more detailed picture of magnetohydrodynamics of solar-like stars is beginning to emerge and discuss future prospects.

description: We show analytically that there exist compact stellar objects akin to neutron stars whose radius is smaller than the Schwarzschild radius defined by Arnowitt-Deser-Misner (ADM) mass. The radius of the compact object is defined by the radius where the energy density and the pressure of ordinary matter vanish, while clouds of scalar(s) can extend beyond this radius -- a situation that is often encountered in modified gravity theories, like $F(R)$ gravity and the scalar--Einstein--Gauss-Bonnet gravity. The clouds of scalar mode(s) give additional contributions to the ADM mass and as a result, the corresponding Schwarzschild radius given by the ADM mass can be larger than that of the compact object.

description: Black holes in X-ray binaries are often assumed to be rotating perpendicular to the plane of the accretion disk and parallel to the orbital plane of the binary. While the Bardeen-Petterson effect forces the inner part of the accretion disk to be aligned with the equatorial plane of a spinning black hole, the disk may be warped such that the inclination angle of the outer part is different from that of the inner part. In this paper, we identify a possible observational signature of a warped accretion disk in the spectrum of the polarization degree of the continuum. Such a signature would provide direct evidence for the presence of a warped disk and, potentially, even a measure of the warp radius, which, in turn, could be used to infer the viscosity parameter of the disk.

description: In recent years, machine learning has very much been a prominent talking point, and is considered by many to be the next big thing, comparable to, if not greater than the dot-com boom of the late 90s. Whilst machine learning and AI are general terms, an area that has seen significant growth both in research and industrial or commercial applications are neural networks, especially those known as deep neural networks, where the increases in processing power available through higher core count CPUs and mutliple high power GPUs have meant that networks can now be far bigger than when they were originally put forward. This work looks at a subsection of this field, focusing on network inference instead of training, and being able to utilise trained networks on multiple platforms as easily as possible. Due to the high growth of the area, there are many specialist tools available to allow users to use neural networks on a wide range of hardware, however in order to test and develop on multiple platforms such as x86 and embedded or FPGA systems, you are required to use multiple tools, each separate from one another. This work aims to provide a single solution allowing a user to test trained networks on multiple platforms, knowing the code base originates from the same core and lowering some of the difficulties that embedded or FPGA platforms can throw up when it comes to developing for them. The system created allows a user to target multiple different platforms, automatically generating code to be used on each, reducing the number of steps required before the network can be up and running on the chosen device. TinyYOLO was the main network used for testing, on multiple x86 platforms, and a Digilent Zedboard for freeRTOS, PetaLinux and FPGA testing.

description: Researchers evaluated the use of the drug misoprostol at Women’s Hospital – Hamad Medical Corporation in Qatar in 33 patients with miscarriage. They found that, despite current practices at the hospital varying from World Health Organization recommended dosages and frequencies, the drug’s use was generally successful.Spontaneous miscarriage is a non-induced termination of pregnancy in the first 20 weeks of gestation. Sometimes pregnancy tissues remain in the uterus as a result of a miscarriage and need to be evacuated medically — with drugs that cause the uterus to contract — or surgically.To manage spontaneous miscarriage, the World Health Organization (WHO) recommends the per vaginal use of the drug misoprostol, a prostaglandin that induces cervical stretching and uterine contractions, in varying doses according to the stage of pregnancy. Higher and more frequent doses are recommended the earlier the stage of pregnancy.“This study was the first of its kind in Qatar to evaluate the indications, appropriateness of dosing and outcomes of misprostol when used for medical evacuation of spontaneous miscarriage,” says clinical pharmacist Samah ElSalem from Qatar’s Women’s Hospital.The study found that medical evacuation was successful in more than 60% of cases. It was particularly successful in patients at 10 to 12 weeks (75% success) and 13 to 22 weeks (54% success) of pregnancy, respectively. Four out of five of patients less than nine weeks pregnant required surgical evacuation of remaining uterine tissue following drug treatment.Current practice at the Women’s Hospital was not always found to be in accordance with WHO recommendations, which can be attributed to a lack of comprehensive knowledge about these recommendations, the researchers report.The sale of misoprostol increased exponentially in the Middle East between 2002 and 2007, with retail pharmacy sales rising by 1,022%. In addition to being effective, it is cheaper than other conventional prostaglandins. It is also a much cheaper option than surgical evacuation, which carries around ten times more personnel costs than medical evacuation using misoprostol.“The study results can be used as a starting point for standardizing the practice and dosing regimen of misoprostol at the Women’s Hospital in Doha, Qatar,” says ElSalem.The researchers are currently in the process of conducting further studies on the use of misoprostol for the medical evacuation of spontaneous miscarriages in patients with a previous caesarean section.

description: Attack Graph (AG) represents the best-suited solution to support cyber risk assessment for multi-step attacks on computer networks, although their generation suffers from poor scalability due to their combinatorial complexity. Current solutions propose to address the generation problem from the algorithmic perspective and postulate the analysis only after the generation is complete, thus implying too long waiting time before enabling analysis capabilities. Additionally, they poorly capture the dynamic changes in the networks due to long generation times. To mitigate these problems, this paper rethinks the classic AG analysis through a novel workflow in which the analyst can query the system anytime, thus enabling real-time analysis before the completion of the AG generation with quantifiable statistical significance. Further, we introduce a mechanism to accelerate the generation by steering it with the analysis query. To show the capabilities of the proposed framework, we perform an extensive quantitative validation and present a realistic case study on networks of unprecedented size. It demonstrates the advantages of our approach in terms of scalability and fitting to common attack path analyses.

This paper explores the various steps in the process of providing synchronous, chat-based reference, as well as issues involved in providing such service at each step. The purpose of this exploration is twofold. First, this paper presents some open research questions at each step in the process of providing chat-based reference service. Second, the entire process of providing chat-based reference is viewed as a whole, and a model of the provision of chat-based reference service is developed at a high level of abstraction. It is hoped that this model may serve as a conceptual framework for future discussions of, and development of applications for chat-based reference.

description: To plan and optimize energy storage demands that account for Li-ion battery aging dynamics, techniques need to be developed to diagnose battery internal states accurately and rapidly. This study seeks to reduce the computational resources needed to determine a battery's internal states by replacing physics-based Li-ion battery models -- such as the single-particle model (SPM) and the pseudo-2D (P2D) model -- with a physics-informed neural network (PINN) surrogate. The surrogate model makes high-throughput techniques, such as Bayesian calibration, tractable to determine battery internal parameters from voltage responses. This manuscript is the first of a two-part series that introduces PINN surrogates of Li-ion battery models for parameter inference (i.e., state-of-health diagnostics). In this first part, a method is presented for constructing a PINN surrogate of the SPM. A multi-fidelity hierarchical training, where several neural nets are trained with multiple physics-loss fidelities is shown to significantly improve the surrogate accuracy when only training on the governing equation residuals. The implementation is made available in a companion repository (https://github.com/NREL/pinnstripes). The techniques used to develop a PINN surrogate of the SPM are extended in Part II for the PINN surrogate for the P2D battery model, and explore the Bayesian calibration capabilities of both surrogates.

description: Bayesian parameter inference is useful to improve Li-ion battery diagnostics and can help formulate battery aging models. However, it is computationally intensive and cannot be easily repeated for multiple cycles, multiple operating conditions, or multiple replicate cells. To reduce the computational cost of Bayesian calibration, numerical solvers for physics-based models can be replaced with faster surrogates. A physics-informed neural network (PINN) is developed as a surrogate for the pseudo-2D (P2D) battery model calibration. For the P2D surrogate, additional training regularization was needed as compared to the PINN single-particle model (SPM) developed in Part I. Both the PINN SPM and P2D surrogate models are exercised for parameter inference and compared to data obtained from a direct numerical solution of the governing equations. A parameter inference study highlights the ability to use these PINNs to calibrate scaling parameters for the cathode Li diffusion and the anode exchange current density. By realizing computational speed-ups of 2250x for the P2D model, as compared to using standard integrating methods, the PINN surrogates enable rapid state-of-health diagnostics. In the low-data availability scenario, the testing error was estimated to 2mV for the SPM surrogate and 10mV for the P2D surrogate which could be mitigated with additional data.

description: We are investigating the potential of 3D telepresence, or televideo, technology to support collaboration among geographically separated medical personnel in trauma emergency care situations. 3D telepresence technology has the potential to provide richer visual information than current 2D video conferencing techniques. This may be of benefit in diagnosing and treating patients in emergency situations where specialized medical expertise is not locally available. The 3D telepresence technology does not yet exist and there is a need to understand its potential before resources are spent on its development and deployment. This poses a complex challenge. How can we evaluate the potential impact of a technology within complex, dynamic work contexts when the technology does not yet exist? To address this challenge we conducted an experiment with a post-test, between-subjects design that takes the medical situation and context into account. In the experiment we simulated an emergency medical situation involving practicing paramedics and physicians, collaborating remotely via two conditions: with today’s 2D videoconferencing and a 3D telepresence proxy. In this paper we examine information sharing between the attending paramedic and collaborating physician. Postquestionnaire data illustrate that the information provided by the physician was perceived to be more useful by the paramedic in the 3D proxy condition than the 2D condition. However, data pertaining to the quality of interaction and trust between the collaborating physician and paramedic show mixed results. Post-interview data help explain these results.
Calibrating and Stabilizing Spectropolarimeters with Charge Shuffling and Daytime Sky Measurements

description: Well-calibrated spectropolarimetry studies at resolutions of $R>$10,000 with signal-to-noise ratios (SNRs) better than 0.01\% across individual line profiles, are becoming common with larger aperture telescopes. Spectropolarimetric studies require high SNR observations and are often limited by instrument systematic errors. As an example, fiber-fed spectropolarimeters combined with advanced line-combination algorithms can reach statistical error limits of 0.001\% in measurements of spectral line profiles referenced to the continuum. Calibration of such observations is often required both for cross-talk and for continuum polarization. This is not straightforward since telescope cross-talk errors are rarely less than $\sim$1\%. In solar instruments like the Daniel K. Inouye Solar Telescope (DKIST), much more stringent calibration is required and the telescope optical design contains substantial intrinsic polarization artifacts. This paper describes some generally useful techniques we have applied to the HiVIS spectropolarimeter at the 3.7m AEOS telescope on Haleakala. HiVIS now yields accurate polarized spectral line profiles that are shot-noise limited to 0.01\% SNR levels at our full spectral resolution of 10,000 at spectral sampling of $\sim$100,000. We show line profiles with absolute spectropolarimetric calibration for cross-talk and continuum polarization in a system with polarization cross-talk levels of essentially 100\%. In these data the continuum polarization can be recovered to one percent accuracy because of synchronized charge-shuffling model now working with our CCD detector. These techniques can be applied to other spectropolarimeters on other telescopes for both night and day-time applications such as DKIST, TMT and ELT which have folded non-axially symmetric foci.

description: Given the recent advances in quantum technology, the complexity of quantum states is an important notion. The idea of the Krylov spread complexity has come into focus recently with the goal of capturing this in a quantitative way. The present paper sheds new light on the Krylov complexity measure by exploring it in the context of continuous-time quantum-walks on graphs. A close relationship between Krylov spread complexity and the concept of limiting-distributions for quantum-walks is established. Moreover, using a graph optimization algorithm, quantum-walk graphs are constructed that have minimal and maximal long-time average Krylov $\bar C$-complexity. This reveals an empirical upper bound for the $\bar C$-complexity as a function of Hilbert space dimension and an exact lower bound.

The Effect of Assigning a Metadata or Indexing Term on Document Ordering

description: The assignment of indexing terms and metadata to documents, data, and other information representations is considered useful, but the utility of including a single term is seldom discussed. We discuss a simple model of document ordering and then show how assigning index and metadata labels improves or decreases retrieval performance. The Indexing and Metadata Advantage (IMA) factor measures how indexing or assigning a metadata term helps (or hurts) ordering performance. Performance values and the associated IMA expressions are computed, consistent with several different assumptions. The economic value associated with various term assignment decisions is developed. The IMA term advantage model itself is empirically validated with computer software that shows that the analytic results obtained agree completely with the actual performance gains and losses found when ordering all sets of 14 or fewer documents, while when the formulas in the software are changed to differ from this model, the predictions of the actual performance are erroneous.
