description: This paper compares the winter maintenance performances of sections of two limited access highways operated by the New York State Department of Transportation (NYSDOT) and the New York State Thruway Authority (NYSTA). Performance is assessed by two user mobility indicators: speed reduction during snowstorms and speed recovery duration following the end of snow events. Multivariate linear regressions are estimated to model these mobility indicators. The results show major discrepancies in level of service between the two agencies, particularly in the early stages of snowstorms. Another result is that speed recovery is indistinguishable in the hour following the end of snow events. It also found that NYSTA’s higher outlay of resources appears to be effective only during short storms and in the early stages of storms.

description: The hook components of $V^{\otimes n}$ interpolate between the symmetric power $\sym^n(V)$ and the exterior power $\wedge^n(V)$. When $V$ is the vector space of $k\times m$ matrices over $\bbc$, we decompose the hook components into irreducible $GL_k(\bbc)\times GL_m(\bbc)$-modules. In particular, classical theorems are proved as boundary cases. For the algebra of square matrices over $\bbc$, a bivariate interpolation is presented and studied.

description: Excerpts from the report Summary: Three market layouts are proposed for a livestock auction market in the Appalachian area that sorts animals into grades and market classes and weighs them as they arrive at the market. Each layout is designed for a different number of animals . The No. 1 type of market is designed to handle 400 cattle, 180 calves, 400 sheep, and 300 hogs; the No. 2 market 350 cattle, 125 calves, and 600 hogs; and the No. 3 market 590 cattle, 245 calves, 315 sheep, and 125 hogs. The proposed layouts include improved designs and arrangements of the yards, sales barn, market driveways, unloading and loading aprons, and parking areas for market patrons. Specific designs include improved layouts for the receiving-weighing area and the sales barn. For each of the 3 proposed layouts, the suggested lines of flow during the receiving, selling, and loading out cycles are shown. The estimated costs of constructing the proposed markets, based upon general construction costs in this area in 1957, are: The No. 1 market, $87,209; the No. 2 market, $72,893; and the No. 3 market, $92,330. The cost of the land and the cost of putting the land in condition to build are not included in these estimates.
Influence of damping on the vanishing of the electro-optic effect in chiral isotropic media

Year: 2002
Subjects: subject: Quantum Physics (quant-ph)

description: Using first principles, it is demonstrated that radiative damping alone cannot lead to a nonvanishing electro-optic effect in a chiral isotropic medium. This conclusion is in contrast with that obtained by a calculation in which damping effects are included using the standard phenomenological model. We show that these predictions differ because the phenomenological damping equations are valid only in regions where the frequencies of the applied electromagnetic fields are nearly resonant with the atomic transitions. We also show that collisional damping can lead to a nonvanishing electrooptic effect, but with a strength sufficiently weak that it is unlikely to be observable under realistic laboratory conditions.

description: This paper presents a conditional generative adversarial network (cGAN) that translates base station location (BSL) information of any Region-of-Interest (RoI) to location-dependent coverage probability values within a subset of that region, called the region-of-evaluation (RoE). We train our network utilizing the BSL data of India, the USA, Germany, and Brazil. In comparison to the state-of-the-art convolutional neural networks (CNNs), our model improves the prediction error ($L_1$ difference between the coverage manifold generated by the network under consideration and that generated via simulation) by two orders of magnitude. Moreover, the cGAN-generated coverage manifolds appear to be almost visually indistinguishable from the ground truth.

Bufo

description: Bufo
 Bufo Garsault, 1764, was established for a group of species containing Rana bufo Linnaeus, 1758 or one of its synonyms. First species added by Laurenti 1768 (use of the name was in accordance with Garsault's use of the name, it contained Bufo vulgaris Laurenti, 1768, a junior subjective synonym of Rana bufo Linnaeus, 1758), type species Bufo viridis Laurenti, 1768 fixed by Fitzinger 1843.
 The fact that Garsault 1764 had used the name for a French animal, while Laurenti 1768 had used the synonymous name for presumably Austrian (his own material) and German animals (Rösel's material), has no influence because in these times the French populations were not classified as a different taxon, there is no expressed evidence to support the assumption that Laurenti 1768 would have used the name Bufo in a much different sense than Garsault 1764 had done it.
We agree that Tschudi 1828 was not an unambiguous type designation (Art. 67.5).
 The fact that Bufo vulgaris and Bufo viridis have recently been classified in different genera or subgenera, has no influence on the nomenclatural act of type fixation. The present-day taxonomy has no influence on the nomenclature.
 We reject the names used in the subgeneric classification proposed by Dubois & Bour (2010), because their use was based on incorrect nomenclatural assumptions, following which Fitzinger's 1843 type designation was ignored for the present-day classification. The names used in that classification at subgeneric level should be revised and brought in line with the ICZN Code. In our interpretation Rana bufo will not be classified in the (sub)genus Bufo.
 If researchers think that it would be more convenient to have Rana bufo as the type for Bufo, and Fitzinger's type fixation should be set aside, this needs to be addressed to the Commission.

description: The Open Aviation Area Treaty (OAA) between the European Union (EU) and the United States (U.S.) went into effect on March 30, 2008. Faced with an economic slowdown and unprecedented increase in fuel costs, factors which were uncertain a priori, the projected effects of OAA have been dampened compared to previous projections. In this paper, a framework is offered that combines a parametric approach with uncertainty in demand estimation and forecasts. This framework is then used to generate probabilistic forecasts for U.S.-EU passenger traffic for the period of 2008–2015.

By pure quantum solution we mean a solution in which the quantum potential cannot be ignored with respect to the classical potential, especially in Bohmian quantum gravity we are interested in the case where these two potentials are equal in their magnitude and in fact their sum is zero. Such a solutions are obtained both using the perturbation and using the linear field approximation.

description: The large-scale clustering of matter is impacted by baryonic physics, particularly AGN feedback. Modelling or mitigating this impact will be essential for making full use of upcoming measurements of cosmic shear and other large-scale structure probes. We study baryonic effects on the matter bispectrum, using measurements from a selection of state-of-the-art hydrodynamical simulations: IllustrisTNG, Illustris, EAGLE, and BAHAMAS. We identify a low-redshift enhancement of the bispectrum, peaking at $k\sim 3h\,{\rm Mpc}^{-1}$, that is present in several simulations, and discuss how it can be associated to the evolving nature of AGN feedback at late times. This enhancement does not appear in the matter power spectrum, and therefore represents a new source of degeneracy breaking between two- and three-point statistics. In addition, we provide physical interpretations for other aspects of these measurements, and make initial comparisons to predictions from perturbation theory, empirical fitting formulas, and the response function formalism. We publicly release our measurements (including estimates of their uncertainty due to sample variance) and bispectrum measurement code as resources for the community.

description: An investigation is conducted on the effect of financial distress on customer service levels in the U.S. airline industry. Using data from the first quarter of 1998 to the third quarter of 2006, we employ a seemingly unrelated regressions (SUR) model to analyze the impact of financial distress on three measures of customer service. We find that higher financial distress is associated with better on-time performance of airlines and fewer lost bags. The relationship of airline financial distress to the number of bumped customers, however, is insignificant.

description: The Alabama Transportation Infrastructure Model (ATIM) is a discrete event simulation of major transportation routes. The model is currently being validated; however, due to limited data and projected changes in traffic patterns, common validation methods (comparison to real-world figures and utilizing historical data to forecast future trends) are impractical. Therefore, an alternative validation approach was developed, using a scenario planning technique known as extreme-world view that allows model developers to test a wider range of model inputs than using limited current or historical data. The model’s response to a range of scenarios indicates it tracks expected real-world performance well.

description: Economic theory shows that education is critical to economic development and to labor sector choice, yet there is little research to indicate the role school access plays in the agricultural transformation, the stage of development when the labor force shifts from primarily agriculture to non-agriculture. This paper identifies the impact of secondary school access on the probability of working in agriculture using 31 years of household panel data nationally representative of rural Mexico. The findings show that local secondary school access reduces the probability of working in agriculture at age 20 by 5.4 percentage points and the impacts grow as individuals age. The model shows that instrumenting for education using changes in school supply leads to inflated coefficient estimates when there are heterogeneous returns to education across labor sectors. This is consistent with the empirical literature, which typically finds greater returns to education using instrumental variables compared to OLS. Nevertheless, estimating the reduced form impacts of school supply on labor decisions has important implications for policy makers. The findings in this paper show that increased rural education is a significant contributor to the agricultural transformation, which leads to higher incomes in both the farm and non-farm sectors.
Wigner crystallization of electrons in a one-dimensional lattice: a condensation in the space of states

description: We study the ground state of a system of spinless electrons interacting through a screened Coulomb potential in a lattice ring. By using analytical arguments, we show that, when the effective interaction compares with the kinetic energy, the system forms a Wigner crystal undergoing a first-order quantum phase transition. This transition is a condensation in the space of the states and belongs to the class of quantum phase transitions discussed in J. Phys.~A \textbf{54}, 055005 (2021). The transition takes place at a critical value ${r_s}_{c}$ of the usual dimensionless parameter $r_s$ (radius of the volume available to each electron divided by effective Bohr radius) for which we are able to provide rigorous lower and upper bounds. For large screening length these bounds can be expressed in a closed analytical form. Demanding Monte Carlo simulations allow to estimate ${r_s}_{c}\simeq 2.3 \pm 0.2$ at lattice filling $3/10$ and screening length 10 lattice constants. This value is well within the rigorous bounds $0.7\leq {r_s}_{c}\leq 4.3$. Finally, we show that if screening is removed after the thermodynamic limit has been taken, ${r_s}_{c}$ tends to zero. In contrast, in a bare unscreened Coulomb potential, Wigner crystallization always takes place as a smooth crossover, not as a quantum phase transition.

description: This paper places conformal testing in a general framework of statistical hypothesis testing. A standard approach to testing a composite null hypothesis $H$ is to test each of its elements and to reject $H$ when each of its elements is rejected. It turns out that we can fully cover conformal testing using this approach only if we allow forgetting some of the data. However, we will see that the standard approach covers conformal testing in a weak asymptotic sense and under restrictive assumptions. I will also list several possible directions of further research, including developing a general scheme of online testing.

We show that this limit of precision for the local quantum states of a pair of N-level systems can be defined by an appropriate class of uncertainty relations. The violation of such local uncertainty relations may be used as an experimental test of entanglement generation.

A real dataset from a bio-climatic house named Sotavento placed on experimental wind farm and located in Xermade (Lugo) in Galicia (Spain) has been collected. Authors have chosen the thermal solar generation system in order to study how works applying several cluster methods followed by a regression technique to predict the output temperature of the system. With the objective of defining the quality of each clustering method two possible solutions have been implemented. The first one is based on three unsupervised learning metrics (Silhouette, Calinski-Harabasz and Davies-Bouldin) while the second one, employs the most common error measurements for a regression algorithm such as Multi Layer Perceptron.

The external applied field is given by a plane Couette shear flow and the problem is studied within the framework of a time-dependent Ginzburg-Landau model. A Fokker-Planck equation for the probability distribution of the concentration fluctuations is developed in a self-consistent one-loop approximation and solved exactly, giving an analytical expression for the dynamic correlation functions of the system. For comparison to experimental work, we also show grey-scale plots of the scattering function at different times during the dynamical process for two different shear rates.

description: I investigate the effect of social norming and financial incentives on promoting physical exercise among randomly selected freshman students. Physical exercise is measured as the number of times an individual visits the recreation center. Social norming involves providing feedback to individuals on own and peers’ physical exercise behavior. The financial incentive allows individuals to win a gift card by having their names entered into a lottery. Previous studies show that social norming and financial incentive have been successful in modifying individual behavior. However, results from my studies using these tools have shown little effect in increasing the individuals’ frequency of physical exercise. The in-effectiveness of social norming can be explained by focus theory. It implies that social norming can instigate students to reduce their positive behavior and might lead to an unintended boomerang effect.

description: We have obtained high-spatial resolution ultraviolet and optical STIS spectroscopy and imaging of the metal-rich nuclear starburst in NGC3049. The stellar continuum and the absorption line spectrum in the ultraviolet are used to constrain the massive stellar population. The strong, blueshifted stellar lines of CIV and SiIV detected in the UV spectra indicate a metal-rich, compact, massive (1E6 Msol) cluster of age 3--4 Myr emitting the UV-optical continuum. We find strong evidence against a depletion of massive stars in this metal-rich cluster. The derived age and the upper mass-limit cut-off of the initial mass function are also consistent with the detection of Wolf-Rayet (WR) features at optical wavelengths. As a second independentconstraint on the massive stellar content, the nebular emission-line spectrum is modeled with photoionization codes using stellar spectra from evolutionary synthesis models. However, the nebular lines are badly reproduced by 3--4 Myr instantaneous bursts, as required by the UV line spectrum, when unblanketed WR and/or Kurucz stellar atmospheres are used. The corresponding number of photons above 24 and 54 eV in the synthetic models is too high in comparison with values suggested by the observed line ratios. Since the ionizing spectrum in this regime is dominated by emission from WR stars, this discrepancy between observations and models is most likely the result of incorrect assumptions about the WR stars. Thus we conclude that the nebular spectrum of high-metallicity starbursts is poorly reproduced by models for WR dominated populations. However, the new model set of Smith et al. (2002) with blanketed WR and O atmospheres and adjusted WR temperatures predicts a softer far-UV radiation field, providing a better match to the data.

description: Public-Private Partnerships (PPP) are in the forefront of approaches to funding transportation infrastructure improvements. Highlighted in the highway area by long term leases of the Chicago Skyway and Indiana Toll Road, a variety of states are investigating the use of public private partnerships either as “brownfield” leases like the Chicago and Indiana cases, or “greenfield” Design, Build, Operate, Transfer arrangements. With its pending lease of Midway airport, Chicago has been the first in the United States to lease a major airport. But, these and other PPP projects raise a variety of issues including the length of the lease, toll escalation permitted, use of funds, etc. This paper develops a rationale for PPP’s in transportation, evaluates several approaches to PPP’s using this rationale, and analyzes some of the difficult issues that can surface.
title: Sound before picture: towards a sound led videographic criticism
Creators: name: Donnelly, Cormac
Publisher: name: University of Glasgow
Year: 2025

description: Videographic criticism has gained a significant foothold within the academic film studies community as a form of research and publication. The number of journals that now accept video essays as scholarly publications has grown over the last decade, and videographic works are now finding exhibition opportunities at film festivals and conferences, often bridging or balancing on the point between artistic and academic practice. Video essay courses and modules are also now part of undergraduate and postgraduate teaching at universities in the UK, Europe, and the United States. A growing body of critical writing and discussion has developed around the scholarly video essay, though there is a noticeable absence of discussion focused on the technical craft and skills involved in the making of videographic work, especially in relation to technical sound skills.

This thesis seeks to understand the role of aesthetic and technical sound skills in videographic criticism. Through analysis of published works, critical discussion, and practical engagement in the making of video essays, it will consider the contribution technical sound skills might make to this developing form of academic engagement. It will also seek to identify a means by which critical discussions and critical engagement with the technical aspects of videographic making, and specifically technical sound literacy, might be developed within the wider community of videographic critics.

description: Strong electron correlations have long been recognized as driving the emergence of novel phases of matter. A well recognized example is high-temperature superconductivity which cannot be understood in terms of the standard weak-coupling theory. The exotic properties that accompany the formation of the two-channel Kondo effect including the emergence of an unconventional metallic state in the low-energy limit also originate from strong electron interactions. Despite its paradigmatic role for the formation of non-standard metal behavior, the stringent conditions required for its emergence have made the observation of the nonmagnetic, orbital two-channel Kondo effect in real quantum materials difficult, if not impossible. We report the observation of orbital one- and two-channel Kondo physics in the symmetry-enforced Dirac nodal line metals IrO2 and RuO2 nanowires and show that the symmetries that enforce the existence of Dirac nodal lines also promote the formation of nonmagnetic Kondo correlations. Rutile oxide nanostructures thus form a versatile quantum matter platform to engineer and explore intrinsic, interacting topological states of matter.

description: We present a fuzzy version of the Group Identification Problem ("Who is a J?") introduced by Kasher and Rubinstein (1997). We consider a class $N = \{1,2,\ldots,n\}$ of agents, each one with an opinion about the membership to a group J of the members of the society, consisting in a function $π: N \to [0; 1]$, indicating for each agent, including herself, the degree of membership to J. We consider the problem of aggregating those functions, satisfying different sets of axioms and characterizing different aggregators. While some results are analogous to those of the originally crisp model, the fuzzy version is able to overcome some of the main impossibility results of Kasher and Rubinstein.

description: A theoretical formula for the probability density function (PDF) of velocity derivatives in a fully developed turbulent flow is derived with the multifractal aspect based on the generalized measures of entropy, i.e., the extensive Renyi entropy or the non-extensive Tsallis entropy, and is used, successfully, to analyze the PDF's observed in the direct numerical simulation (DNS) conducted by Gotoh et al.. The minimum length scale r_d/eta in the longitudinal (transverse) inertial range of the DNS is estimated to be r_d^L/eta = 1.716 (r_d^T/eta = 2.180) in the unit of the Kolmogorov scale eta.

description: A normalized positive operator measure $X\mapsto E(X)$ has the norm-1-property if $\no{E(X)}=1$ whenever $E(X)\ne O$. This property reflects the fact that the measurement outcome probabilities for the values of such observables can be made arbitrary close to one with suitable state preparations. Some general implications of the norm-1-property are investigated. As case studies, localization observables, phase observables, and phase space observables are considered.

description: We study how close passages of interstellar objects of planetary and substellar masses may affect the immediate and long-term dynamics of the Solar system. We consider two nominal approach orbits, namely, the orbits of actual interstellar objects 1I/'Oumuamua and 2I/Borisov, assuming them to be typical or representative for interstellar swarms of matter. Thus, the nominal orbits of the interloper in our models cross the inner part of the Solar system. Series of massive numerical experiments are performed, in which the interloper's mass is varied with a small step over a broad range. We find that, even if a Jovian-mass interloper does not experience close encounters with the Solar system planets (and this holds for our nominal orbits), our planetary system can be destabilised on timescales as short as several million years. In what concerns substellar-mass interlopers (free-floating brown dwarfs), an immediate (on a timescale of $\sim 10 - 100$ yr) consequence of such a MISO flyby is a sharp increase in the orbital eccentricities and inclinations of the outer planets. On an intermediate timescale ($\sim 10^3 - 10^5$ yr after the MISO flyby), Uranus or Neptune can be ejected from the system, as a result of their mutual close encounters and encounters with Saturn. On a secular timescale ($\sim 10^6 - 10^7$ yr after the MISO flyby), the perturbation wave formed by secular planetary interactions propagates from the outer Solar system to its inner zone.

description: Understanding the structure of communities in a network has a great importance in the economic analysis. Communities are indeed characterized by specific properties, that are different from those of both the individual node and the whole network, and they can affect various processes on the network. In the International Trade Network, community detection aims to search sets of countries (or of trade sectors) which have a high intra-cluster connectivity and a low inter-cluster connectivity. In general, exchanges among countries occur according to preferential economic relationships ranging over different sectors. In this paper, we combine community detection with specific topological indicators, such as centrality measures. As a result, a new weighted network is constructed by the original one, in which weights are determined taking into account all the topological indicators in a multi-criteria approach. To solve the resulting Clique Partitioning Problem and find homogeneous group of nations, we use a new fast algorithm, based on quick descents to a local optimal solution. The analysis allows to cluster countries by interconnections, economic power and intensity of trade, giving an important overview on the international trade patterns.

description: Expert outlooks on the future path of oil prices are often relied on by industry participants and policymaking bodies for their forecasting needs. Yet little attention has been paid to the extent to which these area accurate. Using the regular publications by the Energy Information Administration (EIA), we examine the accuracy of annual recursive oil price forecasts generated by the National Energy Modeling System model of the Agency for forecast horizons of up to 15 years. Our results reveal that the EIA model is quite successful at beating the benchmark random walk model, but only at either end of the forecast horizons. We also show that, for the longer horizons, simple econometric forecasting models often produce similar if not better accuracy than the EIA model. Among these, time-varying specifications generally also exhibit stability in their forecast performance. Finally, while combining forecasts does not change the overall patterns, some additional accuracy gains are obtained at intermediate horizons, and in some cases forecast performance stability is also achieved.
A Disk--Jet interaction model for the X--Ray Variability in Microquasars
Creators: name: Nobili, Luciano
Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We propose a simple dynamical model that may account for the observed spectral and temporal properties of GRS 1915+105 and XTE J1550-5634. The model is based on the assumption that a fraction of the radiation emitted by a hot spot lying on the accreting disk is dynamically Comptonized by the relativistic jet that typically accompanies the microquasar phenomenon. We show that scattering by the jet produces a detectable modulation of the observed flux. In particular, we found that the phase lag between hard and soft photons depends on the radial position of the hot spot and, if the angle between the jet and the line of sight is sufficiently large, the lags of the fundamental and its harmonics may be either positive or negative.

description: Excerpts from the report: In 1958 the average American consumed about 97.4 pounds of refined sugar. This was 0.3 percent pound more than the 1957 average per person. In 1957, cane sugar refiners, beet sugar processors, and importers of direct-consumption sugar (sugar for use without further refining) delivered to users the equivalent of 49 million 100-pound bags of refined sugar in consumer-size packages (less than 50 pounds per package). Most sugar cane goes through two stages of processing to produce the refined sugar used in the household. The first stage--crushing of the cane and extracting and boiling of the cane juice--is done in raw sugar mills located in the sugar cane producing areas. These mills produce raw sugar and various byproducts such as molasses and bagasse, the crushed sugar cane stalk. Most of the sugar brought into this country from foreign sources is in the form of raw cane sugar. The raw sugar is put through the second stage--the refining process--in refineries located mainly in or near large port cities. Refined sugar from beets is produced in a single plant operation, and the principal byproducts are beet molasses and beet pulp. This report provides a brief description of the marketing of raw and refined cane sugar and beet sugar, of sugar marketing practices, of the price spread between farmers and household consumers, and of changes that have occurred, in the cost of performing various marketing operations in recent years

Indian Short-finned Eel
 Within Australia, this species is known only from the Kimberley and Pilbara (Indian Ocean Drainage Division, see Fig. 1) (Morgan & Gill 2004). The Kimberley distribution is sporadic (Fig. 4), with few specimens in the WAM and single site records during each of the studies by Allen (1975), Hutchins (1981), Morgan et al. (2002, 2004a) and Storey (2003) (Fig. 4). Within the Kimberley, A. bicolor is known from the Fitzroy, Prince Regent and Ord Rivers, and it has also been collected in Crystal Creek (Admiralty Gulf) and in Doubtful Bay (WAM records). Anguilla bicolor is also found in Tunnel Creek (May River) (Morgan, unpublished data). The sporadic distribution of A. bicolor throughout the Kimberley is probably a reflection of the number of natural barriers (waterfalls) that occur throughout the rivers of the region, which would limit the ability of the species to colonise many of its rivers.

description: Quantifying extra functions, herein referred to as outcome functions, over optimal solutions of an optimization problem can provide decision makers with additional information on a system. This bears more importance when the optimization problem is subject to uncertainty in input parameters. In this paper, we consider linear programming problems in which input parameters are described by real-valued intervals, and we address the outcome range problem which is the problem of finding the range of an outcome function over all possible optimal solutions of a linear program with interval data. We give a general definition of the problem and then focus on a special class of it where uncertainty occurs only in the right-hand side of the underlying linear program. We show that our problem is computationally hard to solve and also study some of its theoretical properties. We then develop two approximation methods to solve it: a local search algorithm and a super-set based method. We test the methods on a set of randomly generated instances. We also provide a real case study on healthcare access measurement to show the relevance of our problem for reliable decision making.
