description: Ta$_{2}$S$_{2}$C compound undergoes superconducting transitions at $T_{cl} = 3.60 \pm 0.02$ K and $T_{cu} = 9.0 \pm 0.2$ K. The nature of successive superconducting transitions has been studied from electrical resistivity, linear and nonlinear AC magnetic susceptibilities. The resistivity $ρ$ at $H$ = 0 shows a local maximum near $T_{cu}$, a kink-like behavior around $T_{cl}$, and reduces to zero at below $T_{0}$ = 2.1 K. The $\ln T$ dependence of $ρ$ is observed at $H$ = 50 kOe at low temperatures, which is due to two-dimensional weak-localization effect. Below $T_{cu}$ a two-dimensional superconducting phase occurs in each TaC layer. The linear and nonlinear susceptibilities $χ_{1}^{\prime\prime}$, $χ_{3}^{\prime}$, $χ_{5}^{\prime}$, and $χ_{7}^{\prime}$ as well as the difference $δχ$ ($= χ_{FC} - χ_{ZFC}$) between the FC and ZFC susceptibilities, start to appear below 6.0 K, the onset temperature of irreversibility. A drastic growth of the in-plane superconducting coherence length below 6.0 K gives rise to a three-dimensional superconducting phase below $T_{cl}$, through interplanar Josephson couplings between adjacent TaC layers. The oscillatory behavior of $χ_{3}^{\prime\prime}$, $χ_{5}^{\prime\prime}$, and $χ_{7}^{\prime\prime} $ below $T_{cl}$ is related to the nonlinear behavior arising from the thermally activated flux flow.

description: We study synchronization and consensus in a group of dynamical systems coupled via multiple directed networks. We show that even though the coupling in a single network may not be sufficient to synchronize the systems, combination of multiple networks can contribute to synchronization. We illustrate how the effectiveness of a collection of networks to synchronize the coupled systems depends on the graph topology. In particular, we show that if the graph sum is a directed graph whose reversal contains a spanning directed tree, then the network synchronizes if the coupling is strong enough. This is intuitive as there is a root node that influence every other node via a set of edges where each edge in the set is in one of the networks.

Subjects: subject: Transportation Engineering

description: This report discusses the development of a computerized soils data system which facilitates collection, centralized storage, and retrieval of soils data developed by engineers and scientists for projects in Kentucky. Without such a system, much soils data are essentially lost after each project is completed. This system will provide data that can conveniently be used for developing preliminary sources of information for site investigation, for preparing regional soil maps, for land use planning, and for studying new and existing empirical relationships involving soil properties and characteristics.  Various types of data systems, the design of the system to include software and hardware, and the contributers and users of the system are discussed. The system is divided into collection, storage, and retrieval subsystems. The operation of each subsystem is discussed. A computerized system was selected as the most efficient. A file definition and coding system was developed and is included in the appendices of the report.

description: We analyze a model of two-leg Hubbard ladders weakly coupled by interladder tunneling. At half filling a semimetallic state with small Fermi pockets is induced beyond a threshold tunneling strength. The sign changes in the single electron Green's function relevant for the Luttinger Sum Rule now take place at surfaces with both zeroes and infinities with important consequences for the interpretation of ARPES experiments. Residual interactions between electron and hole-like quasi-particles cause a transition to long range order at low temperatures. The theory can be extended to small doping leading to superconducting order.

Pedestrian Accidents in Kentucky

Publisher: name: Kentucky Transportation Center, University of Kentucky
Year: 1976
Subjects: subject: Transportation Engineering

description: When a pedestrian is hit by a motor vehicle, he is usually injured or killed; there is no protective cushion to absorb the impact. The high concentration of pedestrians in urban areas, coupled with heavy vehicle traffic, often results in large numbers of pedestrian accidents. In rural areas, there are considerably fewer pedestrians but traffic speeds are higher and, therefore, accidents are more often fatal.  Pedestrian fatalities have increased in the United States from about 7,800 in 1960 to approximately 10,500 in 1973 (1). There are 120,000 pedestrian accidents each year. Total traffic accidents in the US number about 17 million annually with about 56,000 fatalities. Thus, pedestrian accidents account for less than one percent of the total traffic accidents nationwide but over 18 percent of all traffic fatalities. Total accident costs from pedestrian accidents amount to over $1.2 billion annually (using $3,400 per injury and $82,000 per fatality) (2).  In 1973, there were an estimated 1,500 pedestrian accidents in Kentucky in which 167 pedestrians died. This is a pedestrian death rate of 5.2 deaths per 100,000 population compared to the national rate of 5.0 (1). The pedestrian death rate in Kentucky has exceeded the national rate in nine of the last 14 years since 1960. The number of pedestrian deaths in Kentucky has varied between 129 and 167 annually since 1960 (3). Total costs for pedestrian accidents in Kentucky amounted to over $18 million in 1973.  Kentucky is predominantly a rural state. Since 1960, most pedestrian fatalities have occurred in rural areas. However, only 342 pedestrian accidents have occurred annually on the rural state-maintained highway system out of an estimated 1,500 pedestrian accidents in Kentucky in 1973. Nearly 30 percent of all rural pedestrian accidents are fatalities whereas only 4 percent were fatalities in urban areas. There were virtually no property-damage-only pedestrian accidents reported.  To obtain information on rural pedestrian accidents, files of state-police-reported rural accidents for 1972 and 1973 were searched. To study pedestrian accidents in urban areas, data were obtained directly from local police departments of cities -- Louisville, Lexington, Covington, Owensboro, Bowling Green, Paducah, Ashland, Newport, and Frankfort. The populations of these cities range from about 362,000 (Louisville) to about 22,000 (Frankfort). The accident information was analyzed to determine major causes and patterns of pedestrian accidents.

description: The study of topological properties by machine learning approaches has attracted considerable interest recently. Here we propose machine learning the topological invariants that are unique in non-Hermitian systems. Specifically, we train neural networks to predict the winding of eigenvalues of four prototypical non-Hermitian Hamiltonians on the complex energy plane with nearly $100\%$ accuracy. Our demonstrations in the non-Hermitian Hatano-Nelson model, Su-Schrieffer-Heeger model and generalized Aubry-André-Harper model in one dimension, and two-dimensional Dirac fermion model with non-Hermitian terms show the capability of the neural networks in exploring topological invariants and the associated topological phase transitions and topological phase diagrams in non-Hermitian systems. Moreover, the neural networks trained by a small data set in the phase diagram can successfully predict topological invariants in untouched phase regions. Thus, our work paves the way to revealing non-Hermitian topology with the machine learning toolbox.

description: There are many expenditure options available to farmers who received a tobacco buyout check. We used a multinomial logit model to analyze how farmer, business, and household characteristics influenced the choice of expenditure option. We found statistically significant differences in the way farmers chose to spend their buyout money based on age, education, gender, and internet use. We also found that farmer optimism had a statistically significant impact on expenditure choice. Overall, our analysis suggests that it is important for policymakers to take into account this heterogeneity instead of treating all farmers as a homogeneous group of representative agents.

Landscape aesthetics and surface mine reclamation : establishing the efficacy of linking ethics, aesthetic preference, ecological health and the concept of sustainable development within the context of a reclamation of an open pit mine
Creators: name: Roberts, Stephen Alexander
Publisher: name: University of British Columbia
Year: 2009

description: The field of mine reclamation has traditionally been dominated by engineers and biologists. With a few notable exceptions, landscape architects in North America have not shown a willingness to participate in reclamation activities. This unwillingness was primarily the result of the perception that the contribution of landscape architects as place-makers was irrelevant due to the often remote location of these mine sites. With advances in transportation, communications, and a rapidly expanding human population, areas that were once considered remote are now accessible. With the rise in social activism resulting from the public's desire for more sustainable forms of economic development, the government has responded by placing ever-increasing restrictions on where mines can be developed in the province of British Columbia. In response to these actions, mine operators have begun to realize that past mine management practices must now give way to new approaches if the industry is to prosper in Canada. This change has lead to a reappraisal of the role landscape architects can play in mine reclamation. For reasons based on their understanding of ethics, aesthetics, and issues of ecology, the profession appears capable of making important contributions to how mine reclamation should be practiced. Having the ability to effectively link all three themes into a coherent whole, landscape architects can move the direction of mine reclamation toward a set of goals that effectively addresses both human and ecologically-based objectives. As an important first step in this process, mine owners must be willing to accept the consequences of ever increasing public participation in all phases of mine development. Building upon the existing concept of design for closure, this participation would require that members of the affected community be involved in the planning and implementation of the mine closure plan. As a consequence of this long-term involvement, it is envisioned that the mining company and local community will develop a foundation of trust that will form the basis of a more sustainable mining industry. With their commitment to the value of public process, landscape architects can be important facilitators in bringing about this change.

Why black hole production in scattering of cosmic ray neutrinos is generically suppressed

description: It has been argued that neutrinos originating from ultra-high energy cosmic rays produce black holes deep in the atmosphere in models with TeV-scale quantum gravity. Such black holes would initiate quasi-horizontal showers of particles far above the standard model rate, so that the Auger Observatory would observe hundreds of black hole events. This would provide the first opportunity for experimental study of microscopic black holes. However, any phenomenologically viable model with a low scale of quantum gravity must explain how to preserve protons from rapid decay mediated by virtual black holes. We argue that unless this is accomplished by the gauging of baryon or lepton number, the suppression of proton decay will also suppress quantum gravity mediated lepton-nucleon scattering, and hence black hole production by scattering of ultra-high energy cosmic ray neutrinos in the atmosphere. We demonstrate this explicitly for the split fermion solution to the problem of fast proton decay.

description: There is compelling evidence for a strong electron-phonon interaction (EPI) in cuprate superconductors from the isotope effects on the supercarrier mass, high resolution angle resolved photoemission spectroscopies (ARPES), a number of optical and neutron-scattering measurements in accordance with our prediction of high-temperature superconductivity in polaronic liquids. A number of observations point to the possibility that high-Tc cuprate superconductors may not be conventional Bardeen-Cooper-Schrieffer (BCS) superconductors, but rather derive from the Bose-Einstein condensation (BEC) of real-space pairs, which are mobile small bipolarons. Here I review the bipolaron theory of unconventional proximity effects, the symmetry and checkerboard modulations of the order parameter and quantum magneto-oscillations discovered recently in cuprates.

Localized dynamics following a quantum quench in a non-integrable system: An example on the sawtooth ladder

description: Motivated by the recent discovery of ergodicity breaking in geometrically frustrated systems, we study the quench dynamics of interacting hardcore bosons on a sawtooth ladder. We identify a set of initial states for which this system exhibits characteristic signatures of localization like initial state memory retention and slow growth of entanglement entropy for a wide parameter regime. Remarkably, this localization persists even when the many-body spectrum is thermalizing. We argue that the localized dynamics originates from an interaction induced quantum interference. Our results show that the sawtooth ladder can be a fertile platform for realizing non-equilibrium quantum states of matter.

description: The influence of higher-order terms in the Kähler potential of the supergravity D-term inflation model on the density perturbation is studied. We show that these terms can make the inflaton potential flatter, which lowers the energy scale of inflation under the COBE/WMAP normalization. As a result, the mass per unit length of cosmic strings, which are produced at the end of inflation, can be reduced to a harmless but detectable level without introducing a tiny Yukawa coupling. Our scenario can naturally be implemented in models with a low cut-off as in Type I or Type IIB orientifold models.

description: We present the results of a radio monitoring campaign to search for radio emission from nearby ultra-luminous X-ray sources (ULXs). These sources are bright off-nuclear X-ray point sources with luminosities exceeding L_X > 10^39 erg/sec. A well-defined sample of the 9 nearest ULXs has been monitored eight times during 5 months with the Very Large Array in A and B configuration. Our limiting sensitivity is approximately 0.15 mJy (4 sigma) for radio flares and around 60 uJy for continuous emission. In M82 two ULXs seem to have coincident compact radio sources, which are probably supernova remnants. No continuous or flaring radio emission has been detected from any other ULX. Thus, ULXs do not generally emit steady-state radio emission above radio powers of 1.5 10^17 W/Hz. The non-detections of the continuous emission are consistent with beamed or unbeamed radio emission from accreting black holes of <= 10^3 Msol based on the radio/X-ray correlation. Other published radio detections (M82, NGC 5408) are also discussed in this context. Both detections are significantly above our detection limit. If ULXs have flaring radio emission above 4 10^17 W/Hz we can give an upper limit on the duty circle of the flares of 6%. This upper limit is in agreement with the observed number of flares in Galactic radio transients. Additionally we present a yet unreported radio double structure in the nearby low-luminosity AGN NGC 4736.

We use a Generalized Methods of Moments technique to estimate the impact of weather on the price of muscadines with the yield per acre as the instrumented variable. The results suggest that there is a relationship between the price and weather for muscadines, which provide important implications for the potential relevance of a weather derivative for muscadine production.

description: This paper has taken into advantage the relationship between Fuzzy Relation Equations (FRE) and Concept Lattices in order to introduce a procedure to reduce a FRE, without losing information. Specifically, attribute reduction theory in property-oriented and object-oriented concept lattices has been considered in order to present a mechanism for detecting redundant equations. As a first consequence, the computation of the whole solution set of a solvable FRE is reduced. Moreover, we will also introduce a novel method for computing approximate solutions of unsolvable FRE related to a (real) dataset with uncertainty/imprecision data.

Efficient Compensation for Regulatory Takings and Oregon's Measure 37
Creators: name: Schieffer, Jack

Year: 2007
Subjects: Resource /Energy Economics and Policy

description: In 2004, an Oregon referendum passed Measure 37, a law requiring compensation for, or waiver of, land-use regulations that decrease property values. A key question is whether this form of compensation for regulatory takings achieves economic efficiency. This paper shows that it does not under a reasonable set of assumptions. Following the recent law-and-economics literature on regulatory takings, this paper uses a two-agent principal-agent model in which the government makes a regulatory decision, the property-owner chooses investment level and/or land use, and the outcome is evaluated from the perspective of social welfare. An efficient rule would provide incentives both for the government to make socially optimal regulatory decisions and for the property-owner to make socially optimal decisions regarding investment in and use of the land. The paper shows that a full-compensation rule similar to Measure 37 can induce efficient decisions under a relatively simple model. The paper then extends the model by introducing factors brought to light by the form of Measure 37's compensation scheme and Oregon's early experiences under the law, including budgetary limits and limits on taxation. In this extended model, the Measure 37 rule is shown to lead to inefficiency in the form of under-regulation.

description: A collective flashing ratchet transports Brownian particles using a spatially periodic, asymmetric, and time-dependent on-off switchable potential. The net current of the particles in this system can be substantially increased by feedback control based on the particle positions. Several feedback policies for maximizing the current have been proposed, but optimal policies have not been found for a moderate number of particles. Here, we use deep reinforcement learning (RL) to find optimal policies, with results showing that policies built with a suitable neural network architecture outperform the previous policies. Moreover, even in a time-delayed feedback situation where the on-off switching of the potential is delayed, we demonstrate that the policies provided by deep RL provide higher currents than the previous strategies.

A method to search for topological signatures in the angular distribution of cosmic objects
Creators: name: Bernui, Armando

Year: 2005
Subjects: subject: Astrophysics (astro-ph)

description: We present a method to search for large angular-scale correlations, termed topological signatures, in the angular distribution of cosmic objects, which does not depend on cosmological models or parameters and is based only on the angular coordinates of the objects. In order to explore Cosmic Microwave Background temperature fluctuations data, we applied this method to simulated distributions of objects in thin spherical shells located in three different multiply-connected Euclidean 3-spaces ($T^3$, $T_π$, and $G_6$), and found that the topological signatures due to these topologies can be revealed even if their intensities are small. We show how to detect such signatures for the cases of full-sky and partial-sky distributions of objects. This method can also be applied to other ensembles of cosmic objects, like galaxies or quasars, in order to reveal possible angular-scale correlations in their distributions.

description: Point cloud registration is a foundational task for 3D alignment and reconstruction applications. While both traditional and learning-based registration approaches have succeeded, leveraging the intrinsic symmetry of point cloud data, including rotation equivariance, has received insufficient attention. This prohibits the model from learning effectively, resulting in a requirement for more training data and increased model complexity. To address these challenges, we propose a graph neural network model embedded with a local Spherical Euclidean 3D equivariance property through SE(3) message passing based propagation. Our model is composed mainly of a descriptor module, equivariant graph layers, match similarity, and the final regression layers. Such modular design enables us to utilize sparsely sampled input points and initialize the descriptor by self-trained or pre-trained geometric feature descriptors easily. Experiments conducted on the 3DMatch and KITTI datasets exhibit the compelling and robust performance of our model compared to state-of-the-art approaches, while the model complexity remains relatively low at the same time.

description: To reduce vulnerability and food insecurity this paper investigates the economics of micro-credit. We provide a model that shows how a micro-credit market based on trust can co-exist with a commercial collateral-based market. This model is developed in detail and certain propositions are supported using dominant strategies in a trust-honour game based on the prisoner's dilemma. From a policy point of view the theoretical model indicates that trust-based lending, coupled with certain incentives, can go far in supporting growth opportunities in developing countries. It is argued that development policy should be flexible enough to permit trust-based micro-lending to the poor, regardless of how counter-intuitive this must appear to the conventional wisdom.

Fermions in Ashtekar-Barbero Connections Formalism for Arbitrary Values of the Immirzi Parameter

description: The Ashtekar-Barbero-Immirzi formulation of General Relativity is extended to include spinor matter fields. Our formulation applies to generic values of the Immirzi parameter and reduces to the Ashtekar-Romano-Tate approach when the Immirzi parameter is taken equal to the imaginary unit. The dynamics of the gravity-fermions coupled system is described by the Holst plus Dirac action with a non-minimal coupling term. The non-minimal interaction together with the Holst modification to the Hilbert-Palatini action reconstruct the Nieh-Yan invariant, so that the effective action coming out is the one of Einstein-Cartan theory with a typical Fermi-like interaction term: in spite of the presence of spinor matter fields, the Immirzi parameter plays no role in the classical effective dynamics and results to be only a multiplicative factor in front of a total divergence. We reduce the total action of the theory to the sum of dynamically independent Ashtekar-Romano-Tate actions for self and anti-self dual connections, with different weights depending on the Immirzi parameter. This allows to calculate the constraints of the complete theory in a simple way, it is only necessary to realize that the Barbero-Immirzi connection is a weighted sum of the self and anti-self dual Ashtekar connections. Finally the obtained constraints for the separated action result to be polynomial in terms of the self and anti-self dual connections, this could have implications in the inclusion of spinor matter in the framework of non-perturbative quantum gravity.

description: Models of social anxiety disorder (SAD) stress the relevance of physiological arousal. So far, limited research has been conducted in children with SAD in experimental stress designs. Thus, examining autonomic arousal, children with and without SAD completed a standardized social stressor (Trier Social Stress Test for Children-C; TSST-C). Pre-existing differences to healthy controls (HC) were expected to decrease after receiving cognitive behavior therapy (CBT). Children with SAD (n = 64) and HC children (n = 55) completed a TSST-C. Children with SAD participated in a second TSST-C after either cognitive-behavioral treatment or a waitlist-control period (WLC). As expected, children with SAD showed blunted heart rate reactivity compared to HC children. Further, children with SAD had elevated levels of tonic sympathetic arousal as indexed by skin conductance level compared to HC. Children with SAD showed lower parasympathetic arousal during the baseline compared to HC. Children receiving treatment did not differ from children in the WLC condition in a repeated social stress test. Psychophysiological differences between children with SAD and HC children could be confirmed as indicated by previous research. The lack of physiological effects of the intervention as an experimental manipulation might be related to slower changes in physiology compared to e.g. cognition.

The Spin Orbit term in the Nuclear Shell Model

Publisher: name: arXiv
Year: 2020
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: Quasi-nuclear systems, representing nuclei with variable size, are studied to investigate the occurrence of the spin-orbit term in the nuclear mean field in the transition from infinite nuclear matter to finite nuclei. Relativistic as well as non-relativistic mean field calculations based on models for the nucleon-nucleon ($NN$) interaction, which fit the $NN$ scattering data, are considered. A very strong correlation between the strength of the spin-orbit term and radius of the nuclear system is observed. The origin of the spin-orbit term is analyzed by inspecting the contributions of the different partial waves and various mesons in a One-Boson-Exchange model of the $NN$ interaction. The influence of correlation effects and the enhancement of the small component of Dirac spinors for nucleons in the nuclear medium is discussed.

subject: carbon offset credits from forestry activities
subject: meta-regression analysis

description: Under Kyoto, forestry activities that sequester carbon can be used to create CO2 offset credits that could obviate the need for lifestyle-changing reductions in fossil fuel use. Credits are earned by storing carbon in forest ecosystems and wood products, although CO2 emissions are also mitigated by delaying deforestation, which accounts for one-quarter of anthropogenic CO2 emissions. Non-permanent carbon offsets from forest activities are difficult to compare with each other and with mitigation strategies because they differ in how long they prevent CO2 from entering the atmosphere. In this paper, we investigate issues of carbon sequestration in detail, but in particular we expand in comprehensive fashion on earlier work comparing carbon mitigation activities according to how long they can lower atmospheric CO2 levels. The duration problem is modeled theoretically. Meta-regression analysis with 1047 observations from 68 studies is then used to determine whether the duration problem leads to inconclusive results between carbon-uptake costs and carbon sequestration. In addition, from the regression analysis, it is possible to estimate potential costs of carbon uptake via forestry activities for various scenarios. It turns out that forestry activities are competitive with emissions reduction in tropical regions and, perhaps, in boreal regions, but certainly not in Europe.
