description: Winner selection by majority, in an election between two candidates, is the only rule compatible with democratic principles. Instead, when the candidates are three or more and the voters rank candidates in order of preference, there are no univocal criteria for the selection of the winning (consensus) ranking and the outcome is known to depend sensibly on the adopted rule. Building upon XVIII century Condorcet theory, whose idea was to maximize total voter satisfaction, we propose here the addition of a new basic principle (dimension) to guide the selection: satisfaction should be distributed among voters as equally as possible. With this new criterion we identify an optimal set of rankings. They range from the Condorcet solution to the one which is the most egalitarian with respect to the voters. We show that highly egalitarian rankings have the important property to be more stable with respect to fluctuations and that classical consensus rankings (Copeland, Tideman, Schulze) often turn out to be non optimal. The new dimension we have introduced provides, when used together with that of Condorcet, a clear classification of all the possible rankings. By increasing awareness in selecting a consensus ranking our method may lead to social choices which are more egalitarian compared to those achieved by presently available voting systems.

description: Excerpts from the Foreword: A team of sociologists, agricultural economists, and other scientists from most Southern States and several Midwestern States are pursuing four research objectives to: (1) identify and measure characteristics of farms and related activities as organizational units; (2) assess the impacts that external variations in social, economic, and institutional factors have on farms of various sizes and types; (3) assess the impact of organizational characteristics and career commitment and well-being of individuals and families on farms; and (4) assess the development of farm size and types as related to population change, patterns of man-land relationships, and community structure. Such efforts will help to describe, predict, and explain the changes in the structure of agriculture. Once that foundation is laid, policymakers and the citizenry they represent should be better able to effectively control these changes to achieve desired directions in farming and agriculture which, in turn, play a vital role in national and international human well-being. The purpose of this bibliography is to offer references to various scientific and policy materials already available on the structure of agriculture. It is hoped that the compilation of materials will help to hasten the creation of a scientific knowledge basis for policy and its social ends.
description: This bibliography was extracted from the Agriculture On-Line Access (AGRICOLA) family of data bases for the years 1970-1979. The various subfiles which comprise AGRICOLA vary widely in matters of coding, in-depth indexing, and abstracting. There is also duplication between various subfiles. Because of these problems and because the compilers wished to retain the abstracts and indexing terms included in the American Agricultural Economics Documentation Center (AAEDC) subfile this bibliography was divided into two parts, Part II: AGRICOLA, Part II: American Agricultural Economics Documentation Center. Part I and Part II, as published, do not duplicate each other. All AGRICOLA citations were matched against the AAEDC subfile and where duplication between AGRICOLA and AAEDC occurred only the AAEDC entry was retained. The remaining AGRICOLA citations were then matched against each other and only a single version of the citation was retained.

description: The major outcome of this thesis is the detection and identification of profound spatial inequalities. These inequalities differ by the level of spatial aggregation, the selected health indicator, the birth cohort, but only partly by sex. The inequalities are exposed by using established population health measures which depict disparities in an absolute (prevalence, life years with and without care need), relative (Health ratio, Odds ratio, Risk ratio), or theory-driven perspective (health scenarios).

description: These are materials associated with the article to be published in the Journal of Social Psychology. Abstract: An experience sampling survey showed that when people seek to support others’ well-being in a given interaction, they experience greater life satisfaction, fulfillment of psychological needs, and lower time pressure through the perception that time spent on others is also time spent on themselves (i.e., nonzero-sum perception of time). In contrast, interpersonal goals to appear competent showed weaker positive indirect effects on psychological well-being, while goals to appear likable showed no significant indirect effects, and goals to avoid an undesirable self-image showed negative indirect effects. Spending time on others feels fulfilling rather than depleting when people have compassionate goals.
Non-existence of the Luttinger-Ward functional and misleading convergence of skeleton diagrammatic series for Hubbard-like models

description: The Luttinger-Ward functional $Φ[\mathbf{G}]$, which expresses the thermodynamic grand potential in terms of the interacting single-particle Green's function $\mathbf{G}$, is found to be ill-defined for fermionic models with the Hubbard on-site interaction. In particular, we show that the self-energy $\mathbfΣ[\mathbf{G}] \propto δΦ[\mathbf{G}]/δ\mathbf{G}$ is not a single-valued functional of $\mathbf{G}$: in addition to the physical solution for $\mathbfΣ[\mathbf{G}]$, there exists at least one qualitatively distinct unphysical branch. This result is demonstrated for several models: the Hubbard atom, the Anderson impurity model, and the full two-dimensional Hubbard model. Despite this pathology, the skeleton Feynman diagrammatic series for $\mathbfΣ$ in terms of $\mathbf{G}$ is found to converge at least for moderately low temperatures. However, at strong interactions, its convergence is to the unphysical branch. This reveals a new scenario of breaking down of diagrammatic expansions. In contrast, the bare series in terms of the non-interacting Green's function $\mathbf{G}_0$ converges to the correct physical branch of $\mathbfΣ$ in all cases currently accessible by diagrammatic Monte Carlo. Besides their conceptual importance, these observations have important implications for techniques based on the explicit summation of diagrammatic series.

description: We consider a quantum particle, moving on a lattice with a tight-binding Hamiltonian, which is subjected to measurements to detect it's arrival at a particular chosen set of sites. The projective measurements are made at regular time intervals $τ$, and we consider the evolution of the wave function till the time a detection occurs. We study the probabilities of its first detection at some time and conversely the probability of it not being detected (i.e., surviving) up to that time. We propose a general perturbative approach for understanding the dynamics which maps the evolution operator, consisting of unitary transformations followed by projections, to one described by a non-Hermitian Hamiltonian. For some examples, of a particle moving on one and two-dimensional lattices with one or more detection sites, we use this approach to find exact expressions for the survival probability and find excellent agreement with direct numerical results. A mean field model with hopping between all pairs of sites and detection at one site is solved exactly. For the one- and two-dimensional systems, the survival probability is shown to have a power-law decay with time, where the power depends on the initial position of the particle. Finally, we show an interesting and non-trivial connection between the dynamics of the particle in our model and the evolution of a particle under a non-Hermitian Hamiltonian with a large absorbing potential at some sites.

description: We apply the logic of the quench action to give an exact analytical expression for the time evolution of the one-body density matrix after an interaction quench in the Lieb-Liniger model from the ground state of the free theory (BEC state) to the infinitely repulsive regime. In this limit there exists a mapping between the bosonic wavefuntions and the free fermionic ones but this does not help the computation of the one-body density matrix which is sensitive to particle statistics. The final expression, given in terms of the difference of the square root of two Fredholm determinants, can be numerically evaluated and is valid in the thermodynamic limit and for all times after the quench.

title: The Derivation of Sodium Density in the Mesosphere and Lower Thermosphere from the Na Lidar Photon Counting Profiles
Creators: name: Xi, Xiaoqi
Publisher: name: Utah State University
Year: 2023

description: Derivation of Sodium (Na) number density from the Na lidar observations requires the in situ temperature and wind information because the absorption cross-section of the Na atom is a function of these dynamic parameters. The Na number density above ~ 110 km altitude was difficult to derive with the conventional algorithm, however. The standard output of the Na number density that utilizes the lidar-measured wind and temperature information falls short at ~ 110 km altitude and above due to the relatively large measurement uncertainties in the two critical parameters (low signal-to-noise ratio). Therefore, an innovative algorithm that may drive the Na number density directly from the Na fluorescence photon counting profiles is required for the Na number density investigation in the aforementioned region. This paper will introduce the innovative algorithm step by step and provide results for the hourly average Na number density and its variations from 2018 to 2021 in summer and winter.
Nonstandard representations of type C affine Hecke algebra from K-operators

description: We construct nonstandard finite-dimensional representations of type C affine Hecke algebra from the viewpoint of quantum integrable models. There exists two classes of nonstandard solutions to the Yang-Baxter equation called the Cremmer-Gervais and Jordanian R-matrices. These R-matrices also satisfy the Hecke-relation, thus can be used to construct nonstandard finite-dimensional representations of type A affine Hecke algebra. We construct the corresponding nonstandard representations for type C affine Hecke algebra by explicitly constructing solutions to the reflection equation under the Hecke relation. We achieve this by taking the finite-dimensional representations and deBaxterizing the K-operators acting on the infinite-dimensional function space, taking advantage of the fact that the Cremmer-Gervais and Jordanian R-matrices can be obtained from the R-operator.

description: A popular approach for testing if two univariate random variables are statistically independent consists of partitioning the sample space into bins, and evaluating a test statistic on the binned data. The partition size matters, and the optimal partition size is data dependent. While for detecting simple relationships coarse partitions may be best, for detecting complex relationships a great gain in power can be achieved by considering finer partitions. We suggest novel consistent distribution-free tests that are based on summation or maximization aggregation of scores over all partitions of a fixed size. We show that our test statistics based on summation can serve as good estimators of the mutual information. Moreover, we suggest regularized tests that aggregate over all partition sizes, and prove those are consistent too. We provide polynomial-time algorithms, which are critical for computing the suggested test statistics efficiently. We show that the power of the regularized tests is excellent compared to existing tests, and almost as powerful as the tests based on the optimal (yet unknown in practice) partition size, in simulations as well as on a real data example.

The role of adverse childhood experiences and shared family meals in deaf children's mental health problems

description: In the general population, adverse childhood experiences (ACEs) are a risk factor for childhood mental health problems. Eating together as a family is oftentimes protective against such concerns; children with access to greater frequency of shared family meals (SFMs) have lower rates of mental health problems than those without. The extent to which these findings generalize to deaf children is largely unknown. Deaf children often experience barriers to full access to language and communication from early in development; these experiences may be linked to higher rates of exposure to ACEs and contribute to the higher rates of mental health problems compared to their hearing peers. This secondary data analysis of the National Survey of Children’s Health survey adds to the literature by examining whether hearing status (hearing or deaf) moderates relationships between frequency of SFMs and mental health problems. Given the significance and potentially compromised communication for deaf children, this study explores the potential for SFMs as a protective factor for deaf children (or not) within the context of the quality of communication access during these meals. The study also examines whether the frequency of SFMs and degree of access to quality parent-child communication are associated with mental health problems for deaf children above-and-beyond cumulative conventional ACEs scores. Findings confirm previous research that more SFMs per week reduced the prevalence of moderate/severe mental health problems amongst hearing children. However, SFM frequency was not associated with mental health problems for deaf children, unless the degree of access to communication was included, which yielded curvilinear relationships with SFM frequency and mental health problems. Additionally, only degree of access to quality parent-child communication was significantly associated with mental health problems above-and-beyond significant relationships between the cumulative scores of conventional ACEs and mental health problems for deaf children. Findings may help health providers and professionals in allied fields engage in prevention efforts or those serving families of deaf children with mental health problems may identify home-based access to communication and language as a major maintaining factor that may need intervention before adulthood.

We examine constraints on the string axion parameters that can be obtained from GW observations. If no signal is detected in a targeted search for GWs from Cygnus X-1 in the LIGO data, the decay constant $f_a$ must be smaller than the GUT scale in the mass range $1.1\times 10^{-12}\mathrm{eV}

Optimal Colored Noise for Estimating Phase Response Curves

description: The phase response curve (PRC) is an important measure representing the interaction between oscillatory elements. To understand synchrony in biological systems, many research groups have sought to measure PRCs directly from biological cells including neurons. Ermentrout et al. and Ota et al. showed that PRCs can be identified through measurement of white-noise spike-triggered averages. The disadvantage of this method is that one has to collect more than ten-thousand spikes to ensure the accuracy of the estimate. In this paper, to achieve a more accurate estimation of PRCs with a limited sample size, we use colored noise, which has recently drawn attention because of its unique effect on dynamical systems. We numerically show that there is an optimal colored noise to estimate PRCs in the most rigorous fashion.

description: In analogy with crystalline solids around us, Wilczek recently proposed the idea of "time crystals" as phases that spontaneously break the continuous time translation into a discrete subgroup. The proposal stimulated further studies and vigorous debates whether it can be realized in a physical system. However, a precise definition of the time crystal is needed to resolve the issue. Here we first present a definition of time crystals based on the time-dependent correlation functions of the order parameter. We then prove a no-go theorem that rules out the possibility of time crystals defined as such, in the ground state or in the canonical ensemble of a general Hamiltonian, which consists of not-too-long-range interactions.

description: Detection of patient-zero can give new insights to the epidemiologists about the nature of first transmissions into a population. In this paper, we study the statistical inference problem of detecting the source of epidemics from a snapshot of spreading on an arbitrary network structure. By using exact analytic calculations and Monte Carlo estimators, we demonstrate the detectability limits for the SIR model, which primarily depend on the spreading process characteristics. Finally, we demonstrate the applicability of the approach in a case of a simulated sexually transmitted infection spreading over an empirical temporal network of sexual interactions.

description: We introduce the strict-weak polymer model, and show the KPZ universality of the free energy fluctuation of this model for a certain range of parameters. Our proof relies on the observation that the discrete time geometric q-TASEP model, studied earlier by A. Borodin and I. Corwin, scales to this polymer model in the limit q->1. This allows us to exploit the exact results for geometric q-TASEP to derive a Fredholm determinant formula for the strict-weak polymer, and in turn perform rigorous asymptotic analysis to show KPZ scaling and GUE Tracy-Widom limit for the free energy fluctuations. We also derive moments formulae for the polymer partition function directly by Bethe ansatz, and identify the limit of the free energy using a stationary version of the polymer model.

description: We consider incomplete observations of stochastic processes governing the spread of infectious diseases through finite populations by way of contact. We propose a flexible semiparametric modelling framework with at least three advantages. First, it enables researchers to study the structure of a population contact network and its impact on the spread of infectious diseases. Second, it can accommodate short- and long-tailed degree distributions and detect potential superspreaders, who represent an important public health concern. Third, it addresses the important issue of incomplete data. Starting from first principles, we show when the incomplete-data generating process is ignorable for the purpose of Bayesian inference for the parameters of the population model. We demonstrate the semiparametric modelling framework by simulations and an application to the partially observed MERS epidemic in South Korea in 2015. We conclude with an extended discussion of open questions and directions for future research.

description: Replacing GaAs by graphene to realize more practical quantum Hall resistance standards (QHRS), accurate to within $10^{-9}$ in relative value, but operating at lower magnetic fields than 10 T, is an ongoing goal in metrology. To date, the required accuracy has been reported, only few times, in graphene grown on SiC by sublimation of Si, under higher magnetic fields. Here, we report on a device made of graphene grown by chemical vapour deposition on SiC which demonstrates such accuracies of the Hall resistance from 10 T up to 19 T at 1.4 K. This is explained by a quantum Hall effect with low dissipation, resulting from strongly localized bulk states at the magnetic length scale, over a wide magnetic field range. Our results show that graphene-based QHRS can replace their GaAs counterparts by operating in as-convenient cryomagnetic conditions, but over an extended magnetic field range. They rely on a promising hybrid and scalable growth method and a fabrication process achieving low-electron density devices.

description: Highest density regions refer to level sets containing points of relatively high density. Their estimation from a random sample, generated from the underlying density, allows to determine the clusters of the corresponding distribution. This task can be accomplished considering different nonparametric perspectives. From a practical point of view, reconstructing highest density regions can be interpreted as a way of determining hot-spots, a crucial task for understanding COVID-19 space-time evolution. In this work, we compare the behaviour of classical plug-in methods and a recently proposed hybrid algorithm for highest density regions estimation through an extensive simulation study. Both methodologies are applied to analyse a real data set about COVID-19 cases in the United States.

In order to use our approach in clinical trials, we want to build a user interface that can also be used by scientists without a background in programming.

description: Absorption of microwave by metallic conductors is exclusively inefficient, though being natively broadband, due to the huge impedance mismatch between metal and free space. Reducing the thickness to ultrathin conductive film may improve the absorbing efficiency, but is still bounded by a maximal 50% limit induced by the field continuity. Here, we show that broadband perfect (100%) absorption of microwave can be realized on a single layer of ultrathin conductive film when it is illuminated coherently by two oppositely incident beams. Such an effect of breaking the 50% limit maintains the intrinsic broadband feature from the free carrier dissipation, and is frequency-independent in an ultrawide spectrum, ranging typically from kilohertz to gigahertz and exhibiting an unprecedented bandwidth close to 200%. In particular, it occurs on extremely subwavelength scales, ~λ/10000 or even thinner, which is the film thickness. Our work proposes a way to achieve total electromagnetic wave absorption in a broadband spectrum of radio waves and microwaves with a simple conductive film.

description: Target trial emulation (TTE) is one method to obtain causal evidence by emulating randomized trials using observational data. To our knowledge, even though a few review papers have focused on TTE usage within specific research fields, there has been no paper published that comprehensively summarizes the quality and implementation of TTE in research more generally. This scoping review is to map the implementation of target trial emulation (TTE), including the study design strategies, limitations, and potential solutions.

description: It has been recently suggested that research on human multitasking is best organized according to three research perspectives, which differ in their focus on cognitive structure, flexibility, and plasticity. Even though it is argued that the perspectives should be seen as complementary, there has not been a formal approach describing or explaining the intersections between the three perspectives. With this theoretical note, we would like to show that the explicit consideration of individual differences is one possible way to elaborate in more detail on how and why the perspectives complement each other. We will define structure, flexibility, and plasticity; describe what constitutes individual differences; will outline selected empirical examples; and raise possible future research questions helping to develop the research field.
Before Roe: The University of Michigan’s Task Force for Problem Pregnancy Counseling

description: In May of 2022, following the leak of a draft opinion for the case Dobbs v. Jackson Women's Health Organization that would overturn Roe v. Wade, the University of Michigan and Michigan Medicine convened a working group to prepare for the possible return of enforcement of Michigan’s 1931 abortion ban. “Before Roe: The University of Michigan’s Task Force for Problem Pregnancy Counseling” joins that effort by exploring how the University of Michigan supported students, faculty, and staff seeking abortion care before the legalization of abortion in the state. After New York reformed its abortion laws in 1970, the University of Michigan referred women to New York abortion clinics to access safe and affordable care. The pre-Roe University of Michigan Task Force for Problem Pregnancy Counseling would eventually work to evaluate and improve the conditions of abortion clinics in both New York and the southeast Michigan area. The Task Force was organized by counselors within the University’s Office of Religious Affairs in collaboration with a nationwide network of clergy providing abortion counseling and referrals to women experiencing “problem pregnancies.” This report uses materials from the University of Michigan’s Bentley Historical Library to tell the story of university professionals determined to provide essential services to women when few others could. This history models how the University of Michigan can work to ensure the well-being of students, faculty, and staff in the new post-Roe era.

Exploring the effect of partial B-site Al3+–Mg2+ dual substitution on optoelectronic, surface, and photocatalytic properties of BaTaO2N

description: BaTaO2N is appraised to be one of the few promising 600 nm-class photocatalysts for solar water splitting. However, the presence of structural defects and low charge separation limits its photocatalytic activity. Compared with mono substitution, dual substitution can be more effective in engineering the structural defects and improving the photocatalytic activity if foreign ions are suitably selected. In this work, we involve a dual-substitution approach to partially substitute Al3+ and/or Mg2+ for Ta5+ in BaTaO2N. By maintaining the maximum concentration of Al3+–Mg2+ dual substitution at 5%, the effect of the Al3+–Mg2+ cosubstituent ratio on the optoelectronic, surface, and photocatalytic properties of BaTaO2N is investigated. The Al3+–Mg2+ dual substitution leads to the shift of optical absorption edge toward shorter wavelengths, increasing the optical bandgap energy of BaTaO2N. This effect is more pronounced in the samples with a higher concentration of Mg2+ due to the replacement of N3− by a large number of O2− to compensate charge balance. The initial reaction rates for the evolution of O2 and H2 reveal the improvement in the photocatalytic activity of BaTaO2N due to the partial Al3+–Mg2+ dual substitution. Higher O2 evolution is observed in the samples with a higher concentration of Mg2+, while the H2 evolution rate significantly relies on the increased concentration of Al3+. According to the density functional theory (DFT) calculations, the effective masses of electrons become slightly lower than that of pristine BaTaO2N after partial Al3+–Mg2+ (co)substitution, while a contrary tendency is observed for the effective masses of holes. The calculated positions of the valence band maximum and conduction band minimum are aligned with respect to the normal hydrogen electrode (NHE), and partial Al3+–Mg2+ (co)substituted BaTaO2N photocatalysts can be promising candidates for visible-light-induced water splitting.

description: This paper introduces the Solar Lab Notebook (SLN), an electronic lab notebook for improving the process of recording and sharing solar related digital information in an organized manner. SLN is a pure web-based application (available online: http://umbra.nascom.nasa.gov/sln) that runs client-side only, employing a clean and very friendly graphical user interface design, and thus providing a true cross-platform user experience. Furthermore, SLN leverages unique technologies offered by modern web browsers, such as the FileReader API, the Blob interface and Local Storage mechanism; it is coded entirely using HTML5, CSS3, and JavaScript, and powered by the extremely well documented XML file format. For high-security labs, it can be utilized as an ultra-portable and secure digital notebook solution, since it is functionally self-contained, and does not require any server-side process running on either the local or a remote system. Finally, the W3C XML Schema language is used to define a list of rules, namely a data standard, that an SLN file must conform to in order to be valid. In this way, developers are able to implement their own validation functions in their projects, or use one of the freely available tools to check if a data file is properly structured. Similarly, scientific groups at different labs can easily share information, being confident about the integrity of the exchanged data.

description: L1 regularized logistic regression consists an important tool in data science and is dedicated to solve sparse generalized linear problems. The L1 regularization is widely used in variable selection and estimation in generalized linear model analysis. This approach is intended to select the statistically important predictors. In this paper we compare the performance of some existing L1 regularized logistic regression methods. The goal of our simulation study is directed toward the variable selection performance of regularized logistic regression in high dimensions. We consider three varying n (number of observations), p (number of predictors) settings and we support this comparison analysis by conducting various simulated experiments taking into consideration the correlation structure of the design matrix.
