description: The ergodic equation is a basic tool in the study of mean-payoff stochastic games. Its solvability entails that the mean payoff is independent of the initial state. Moreover, optimal stationary strategies are readily obtained from its solution. In this paper, we give a general sufficient condition for the solvability of the ergodic equation, for a game with finite state space but arbitrary action spaces. This condition involves a pair of directed hypergraphs depending only on the ``growth at infinity'' of the Shapley operator of the game. This refines a recent result of the authors which only applied to games with bounded payments, as well as earlier nonlinear fixed point results for order preserving maps, involving graph conditions.

description: Transcranial focused ultrasound stimulation (TUS) holds promise for non-invasive neural modulation in treating neurological disorders. Most clinically relevant targets are deep within the brain (near or at its geometric center), surrounded by other sensitive regions that need to be spared clinical intervention. However, in TUS, increasing frequency with the goal of improving spatial resolution reduces the effective penetration depth. We show that by using a pair of 1 MHz, orthogonally arranged transducers we improve the spatial resolution afforded by each of the transducers individually, by nearly 40 fold, achieving a sub-cubic millimeter target volume of $0.24\ mm^3$. We show that orthogonally placed transducers generate highly localized standing waves with Acoustic Radiation Force (ARF) arranged into periodic regions of compression and tension near the target. We further present an extended capability of the orthogonal setup, which is to impart selective pressures--either positive or negative, but not both--on the target. Lastly, we share our preliminary findings that strain can arise from both particle motion and ARF with the former reaching its maximum value at the focus, and the latter remaining null at the focus and reaching its maximum around the focus.
 As the field is investigating the mechanism of interaction in TUS by way of elucidating the mapping between ultrasound parameters and neural response, orthogonal transducers expand our toolbox by making it possible to conduct these investigations at much finer spatial resolutions, with localized and directed (compression vs. tension) ARF and the capability of applying selective pressures at the target.

description: Atiyah's classical work on circular symmetry and stationary phase shows how the $\hat{A}$-genus is obtained by formally applying the equivariant cohomology localization formula to the loop space of a simply connected spin manifold. The same technique, applied to a suitable ''antiholomorphic sector'' in the $\mathbb{C}/Λ$-equivariant cohomology of the conformal double loop space $\mathrm{Maps}(\mathbb{C}/Λ,X)$ of a rationally string manifold $X$ produces the Witten genus of $X$. This can be seen as an equivariant localization counterpart to Berwick-Evans supersymmetric localization derivation of the Witten genus.

Macular degeneration

description: As consumers search for an increasing amount of health information online, it is important for the information that they find to not only be accurate, but written in an appropriate and accessible level of readability. Eight consumer health information websites were selected and a portion of text from each on the topic of macular degeneration, an eye disease that affects many older Americans and can result in the loss of central vision, was evaluated. The readability of the text was calculated using two tests: the Flesch-Kincaid Grade Level Index and the Flesch Reading Ease test. These calculations confirmed expectations that online consumer health information for macular degeneration is incomprehensible for a sizeable segment of the American population. According to the results, this information is written on average at a reading level of nearly the eleventh grade.
Ratios of the light quark masses: Cubic curve vs ellipse

Publisher: name: arXiv
Year: 2024
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The bounds on the light quark masses are obtained by fitting the squares of pseudoscalar meson masses $m_π^2$ and $m_K^2$ to second order in $1/N_c$ expansion. The result is an algebraic cubic curve whose coefficients are the known Weinberg values for the quark mass ratios $m_u/m_d$ and $m_s/m_d$. Additional restrictions arise when using the ratio $m_s/m_{ud}=27.23(10)$ quoted by FLAG for lattice simulations with four quark flavors. This provides a tight constraint on the ratio $m_u/m_d = 0.455(8)$.

description: In large part because of his methods - cutting maps out of rare books during open hours and under observation - infamous thief Gilbert Bland caused shockwaves in the academic library community in the 1990s and highlighted attention on the lack of comprehensive security measures in place in rare books and special collections repositories. Archivists and curators from the institutions targeted by Bland were interviewed to determine how much the Bland incidents affected the security measures in place. Interviews were also conducted with curators at institutions not targeted by Bland to determine if Bland's crimes had an effect on the wider professional community. Additionally, a review of the professional literature was undertaken to evaluate the evolution of recommended security guidelines.

description: We find empirical evidence that mean-reverting jump processes are not statistically adequate to model electricity spot price spikes but independent, signed sums of such processes are statistically adequate. Further we demonstrate a change in the composition of these sums after a major economic event. This is achieved by developing a Markov Chain Monte Carlo (MCMC) procedure for Bayesian model calibration and a Bayesian assessment of model adequacy (posterior predictive checking). In particular we determine the number of signed mean-reverting jump components required in the APXUK and EEX markets, in time periods both before and after the recent global financial crises. Statistically, consistent structural changes occur across both markets, with a reduction of the intensity and size, or the disappearance, of positive price spikes in the later period. All code and data are provided to enable replication of results.

description: We introduce multiple parametrized circuit ansätze and present the results of a numerical study comparing their performance with a standard Quantum Alternating Operator Ansatz approach. The ansätze are inspired by mixing and phase separation in the QAOA, and also motivated by compilation considerations with the aim of running on near-term superconducting quantum processors. The methods are tested on random instances of a weighted quadratic binary constrained optimization problem that is fully connected for which the space of feasible solutions has constant Hamming weight. For the parameter setting strategies and evaluation metric used, the average performance achieved by the QAOA is effectively matched by the one obtained by a "mixer-phaser" ansatz that can be compiled in less than half-depth of standard QAOA on most superconducting qubit processors.

description: The probability of the formation and decay of a dinuclear system is investigated for a wide range of relative orbital angular momentum values. The mass and angular distributions of the quasifission fragments are studied to understand the reaction mechanisms of the heavy ion collision of $^{78}$Kr(10$A$ MeV) + $^{40}$Ca within dinuclear system model. The quasifission products are found to contribute to the mass-symmetric region of the mass distribution in collisions with a large orbital angular momentum. The analysis of mass and angular distributions of quasifission fragments shows the possibility of the $180^\circ$ rotation of the system so that projectile-like products can be observed in the forward hemisphere with large cross sections, which can explain the phenomenon observed recently in the ISODEC experiment.

description: Alzheimer's disease is the most common dementia worldwide. Its pathological development is well known to be connected with the accumulation of two toxic proteins: tau protein and amyloid-$β$. Mathematical models and numerical simulations can predict the spreading patterns of misfolded proteins in this context. However, the calibration of the model parameters plays a crucial role in the final solution. In this work, we perform a sensitivity analysis of heterodimer and Fisher-Kolmogorov models to evaluate the impact of the equilibrium values of protein concentration on the solution patterns. We adopt advanced numerical methods such as the IMEX-DG method to accurately describe the propagating fronts in the propagation phenomena in a polygonal mesh of sagittal patient-specific brain geometry derived from magnetic resonance images. We calibrate the model parameters using biological measurements in the brain cortex for the tau protein and the amyloid-$β$ in Alzheimer's patients and controls. Finally, using the sensitivity analysis results, we discuss the applicability of both models in the correct simulation of the spreading of the two proteins.

Selective dissemination of information

description: Access control is a fundamental safeguard for protecting corporate information contained in computer files (herein documents). In the de facto industry standard implementation, the most granular access control specification available is to define the entry on the entire document object. Given the proliferation of data privacy regulations mandating varying degrees of information security controls and practices, one must consider to what extent inefficiency arises due to the withholding from a collaborative workflow relevant information entwined with discrete sensitive information of which not all members of the workflow are authorized to access. Contemporary research in the field proposes a digital metamorphosis of the analogue document redaction paradigm. This research explores the aforementioned inefficiency phenomenon as well as purported utility of redaction through examination of survey data from faculty and staff at a public University.

description: This study addresses the intersection of digital repositories and archives and institutional review boards (IRBs) with regard to opinions on data reuse from the IRB members themselves and researchers in social and behavioral science disciplines whose research requires IRB approval. The issue was examined from several perspectives, utilizing a survey of social and behavioral science researchers, interviews with IRB members, and an analysis of the language used in blank Informed Consent forms from previously approved studies related to potential data reuse. Combined, the data gathered provides multi-faceted insight into these two groups, especially regarding IRB application language and subjects' informed consent. It recommends early intervention by repositories, open discussion within Institutional Review Boards on data archiving in social and behavioral science, increased guidance by IRBs and repositories for applicants, continued education, and increased transparency and communication among IRBs and researchers.
Investigation of nonlocal data-driven methods for subgrid-scale stress modelling in large eddy simulation

description: A nonlocal subgrid-scale stress (SGS) model is developed based on the convolution neural network (CNN), a powerful supervised data-driven approach. The CNN is an ideal approach to naturally consider nonlocal spatial information in prediction due to its wide receptive field. The CNN-based models used here only take primitive flow variables as input, then the flow features are automatically extracted without any $priori$ guidance. The nonlocal models trained by direct numerical simulation (DNS) data of a turbulent channel flow at $Re_τ=178$ are accessed in both the $priori$ and $posteriori$ test, providing physically reasonable flow statistics (like mean velocity and velocity fluctuations) closing to the DNS results even when extrapolating to a higher Reynolds number $Re_τ=600$. In our model, the backscatter is also predicted well and the numerical simulation is stable. The nonlocal models outperform local data-driven models like artificial neural network and some SGS models, e.g. the Smagorinsky model in actual large eddy simulation (LES). The model is also robust since stable solutions can be obtained when examining the grid resolution from one-half to double of the spatial resolution used in training. We also investigate the influence of receptive fields and suggest using the two-point correlation analysis as a quantitative method to guide the design of nonlocal physical models. To facilitate the combination of machine learning (ML) algorithms to computational fluid dynamics (CFD), a novel heterogeneous ML-CFD framework is proposed. The present study provides the effective data-driven nonlocal methods for SGS modelling in the LES of complex anisotropic turbulent flows.

Radiative Magnetic Reconnection in Astrophysics

subject: FOS: Physical sciences

description: I review a new rapidly growing area of high-energy plasma astrophysics --- radiative magnetic reconnection, i.e., a reconnection regime where radiation reaction influences reconnection dynamics, energetics, and nonthermal particle acceleration. This influence be may be manifested via a number of astrophysically important radiative effects, such as radiation-reaction limits on particle acceleration, radiative cooling, radiative resistivity, braking of reconnection outflows by radiation drag, radiation pressure, viscosity, and even pair creation at highest energy densities. Self-consistent inclusion of these effects in magnetic reconnection theory and modeling calls for serious modifications to our overall theoretical approach to the problem. In addition, prompt reconnection-powered radiation often represents our only observational diagnostic tool for studying remote astrophysical systems; this underscores the importance of developing predictive modeling capabilities to connect the underlying physical conditions in a reconnecting system to observable radiative signatures. This Chapter gives an overview of recent theoretical progress in developing basic physical understanding of radiative reconnection, with a special emphasis on astrophysically important radiation mechanisms like synchrotron, curvature, and inverse-Compton. It also offers a broad review of key high-energy astrophysical applications of radiative reconnection, such as: pulsar wind nebulae and magnetospheres, accreting black-hole coronae and jets in XRBs and AGN, magnetospheres of magnetars, and Gamma-Ray Bursts. Finally, this Chapter discusses the most critical open questions and outlines the directions for future research in this exciting new frontier of plasma astrophysics.

description: Collaboration occurs when two separate organizations come together to achieve a unified goal. Library literature identified program-based, resource-based and service-based collaborations formed to provide better services and resources for library users. This study examined academic-public library collaborations within the Triangle Area of North Carolina through conducting semi-structured interviews with both "sides" of the collaboration by asking: What factors are most important in determining a continued successful collaboration between academic and public libraries? And, how can librarians and library administrators sustain collaborations, especially within this economic  climate? Interviews were conducted with six librarians and resulting interview data was analyzed to identify emerging themes. Collaborative partnerships were unique, but commonalities for success were discovered to include managerial support, geographic proximity, availability of resources, a willingness to pilot and accept the failure of new programs, and positive professional relationships. This study can serve as a resource for creating and sustaining academic-public library collaborations.
Single-photon-added coherent state based measurement transition and its advantages in precision measurement

description: In this work, the measurement transition as well as precision measurement advantages of single-photon-added coherent state after postselected von Neumann measurement are investigated. We noticed that the weak-to-strong measurement transition characterized by the shifts of pointer's position and momentum variables occurred in continuously by controlling a dimensionless parameter associated with system-pointer coupling. We calculate the ratio between the signal-to-noise ratio of nonpostselected and postselected measurements, and the latter is used to find the quantum Fisher information. We found that the single-photon-added coherent pointer state can improve the precision of the measurement processes such as signal-to-noise ratio and parameter estimation after postselected von Neumann measurement characterized by postselection and weak value. Furthermore, contrary to the results of several previous studies, we found that the anomalous large weak values can't improve the precision measurement processes related to single-photon-added coherent state.

We investigate invariant loci for $G$ and obtain upper bounds for its order that depends polynomially on the Chern numbers of $X$ and $\mathcal{F}$. As a consequence, we estimate the order of the automorphism group of some foliations under mild restrictions. We obtain an optimal bound for foliations on the projective plane which is attained by the automorphism groups of the Jouanolou's foliations.

description: The ability of open crowds to produce useful and novel solutions is of significant research and practical interest. Much of the existing research has assumed that crowd participants approach problem-solving autonomously and independently of one another. In the Stack Exchange network, we explored problems posted by open crowds and the sequences of suggestions and comments leading up to a solution that was novel and judged by the solution seeker as useful for solving the problem. In the sequences of suggestions, we found indications of self-organization as the crowd emergently accumulated knowledge in specific patterns that were more likely to lead to accepted solutions. The patterns contained positive and negative forms of feedback ensuring that the crowd would, on its own and without external governance intervention, engage in actions that eventually led to accepted solutions. In total, based on the observed knowledge accumulation patterns, three self-organization principles were derived and incorporated into a theory of self-organization for creative solution generation in open crowds. Our theory development suggests implications for research on open crowds specifically, as well as for research on new organizational forms.

description: As medical libraries are increasingly providing information in electronic format and simultaneously dealing with budget cuts, there is a need to analyze the usage of print and electronic titles being purchased. This study takes place at an academic medical center library and attempts to gather and analyze data from a variety of sources that may influence future print and electronic monograph purchasing decisions. Purchases were broken down by subject and compared against one another in terms of average numbers of loans. Five subject areas were chosen for further, title by title analysis to determine what types of titles circulated more frequently than others. Ultimately, the library wishes to ensure that the materials it selects are the ones that are needed and used, thereby providing the best return on investment for its book dollars while keeping the patrons satisfied with the quality of the collection. A balanced scorecard approach is employed to set goals for increasing circulation of purchased monographs.
Are early-type galaxies quenched by present-day environment? A study of dwarfs in the Fornax Cluster

description: Galaxies undergo processes throughout their lifetimes that ultimately lead to the expulsion of the gas and the cessation of the star-forming activity. This phenomenon commonly known as quenching, can be caused by environmental processes. For this we use the results of Romero-Gómez et al. (2024), who analyzed galaxies from the SAMI-Fornax and ATLAS$^{3D}$ survey. Using t$_{90}$ as an approximation for the quenching time and comparing it with the infall time derived from phase-space models, we determine the probability of the quenching being produced by the local environment of galaxies. Our results reveal a relation between galaxy mass and quenching probability. Down to M$_{\star}$ $\sim$10$^{10}$ M$_{\odot}$, galaxies exhibit almost zero probability of quenching, suggesting their independence from environmental effects. As we move into the mass regime of dwarf galaxies, the probability increases with decreasing mass, highlighting their sensitivity to environmental quenching. For the dwarfs, 10$^{7}$ - 10$^{9}$ M$_{\odot}$, 36$\pm$9% of our observational data are consistent with this hypothesis, challenging the idea that the present-day cluster, Fornax, is the primary driver of quenching in the low mass galaxies. We compare these results with cosmological simulations, selecting galaxies under similar conditions to our observational sample. The simulated sample shows lower quenching probabilities as we move down in mass, only 5$\pm$1% of galaxies meet the quenching criteria. This discrepancy between observations and simulations underlines that modelling quenching is still in its infancy. In general, the number of observed galaxies quenched by their environment is lower than expected, which suggests that pre-processing plays a larger role in galaxy evolution. Ultimately, our results highlight the need for higher-quality simulations and refinement of galaxy formation and evolution models.

description: We use weak gravitational lensing to measure mean mass profiles around Locally Brightest Galaxies (LBGs). These are selected from the SDSS/DR7 spectroscopic and photometric catalogues to be brighter than any neighbour projected within 1.0 Mpc and differing in redshift by $<1000$ km/s. Most ($> 83\%$) are expected to be the central galaxies of their dark matter halos. Previous stacking analyses have used this LBG sample to measure mean Sunyaev-Zeldovich flux and mean X-ray luminosity as a function of LBG stellar mass. In both cases, a simulation of the formation of the galaxy population was used to estimate effective halo mass for LBGs of given stellar mass, allowing the derivation of scaling relations between the gas properties of halos and their mass. By comparing results from a variety of simulations to our lensing data, we show that this procedure has significant model dependence reflecting: (i) the failure of any given simulation to reproduce observed galaxy abundances exactly; (ii) a dependence on the cosmology underlying the simulation; and (iii) a dependence on the details of how galaxies populate halos. We use our lensing results to recalibrate the scaling relations, eliminating most of this model dependence and explicitly accounting both for residual modelling uncertainties and for observational uncertainties in the lensing results. The resulting scaling relations link the mean gas properties of dark halos to their mass over an unprecedentedly wide range, $10^{12.5}

description: We present a fully relativistic framework to evaluate the impact of stochastic inhomogeneities on the prediction of the Hubble-Lemaître diagram. In this regard, we relate the fluctuations of the luminosity distance-redshift relation in the Cosmic Concordance model to the intrinsic uncertainty associated to the estimation of cosmological parameters from high-redshift surveys (up to z = 4). Within this framework and according to the specific of forthcoming surveys as Euclid Deep Survey and LSST, we show that the cosmic variance associated with the measurement of the Hubble constant will not exceed 0.1 $\%$. Thanks to our results, we infer that deep surveys will provide an estimation of the the Hubble constant $H_0$ which will be more precise than the one obtained from local sources, at least in regard of the intrinsic uncertainty related to a stochastic distribution of inhomogeneities.

Information Quality
Survey

description: The purpose of this study was to evaluate the information quality of the Web site for the Jordan Institute for Families (URL of the web site: http://ssw.unc.edu/jif/) -- a research, training and technical assistance arm of the School of Social Work at the University of North Carolina at Chapel Hill. A set of information quality indicators, including accuracy, timeliness, easy understanding, organization, consistent representation and easy navigation, were divided into four categories and evaluated in this study. A survey was conducted to test users' performance of some information-finding tasks and to collect users' assessment of the JIF Web site. A total of 25 subjects voluntarily participated in this survey. The results of the study revealed some significant strengths and weaknesses in the design of the JIF site regarding the information quality. With the findings of the study, a list of recommended changes and suggestions were provided to improve the design of the site, make the information more clearly organized and presented, and make it easier for users to locate information on the site.
Normalized characters of symmetric groups and Boolean cumulants via Khovanov's Heisenberg category

description: In this paper, we study relationships between the normalized characters of symmetric groups and the Boolean cumulants of Young diagrams. Specifically, we show that each normalized character is a polynomial of twisted Boolean cumulants with coefficients being non-negative integers, and conversely, that, when we expand a Boolean cumulant in terms of normalized characters, the coefficients are again non-negative integers. The main tool is Khovanov's Heisenberg category and the recently established connection of its center to the ring of functions on Young diagrams, which enables one to apply graphical manipulations to the computation of functions on Young diagrams. Therefore, this paper is an attempt to deepen the connection between the asymptotic representation theory and graphical categorification.
