description: This paper describes a large survey to better understand specialized transportation resources and how they are being used. The survey had two key characteristics. The first was to question both organizations that provide transportation, and those that do not provide it but are actively involved in purchasing or arranging it on behalf of their clients. The second was to be comprehensive; that is, to survey any organization that might be involved either in providing or arranging transportation. The results fall into two broad categories. The first is the actual survey findings, which provide a broad and comprehensive overview of the types of transportation-related activities that organizations are engaged in. Most significantly, about 45% of the diverse organizations that were surveyed provide transportation in some form, and another 20% actively arrange transportation for their clients. This confirms the common belief that the true size of the specialized transportation “system” is far larger than the formal network that is known to transportation funders and regulators. Because the survey was intended to be broad and exploratory rather than focused and definitive, the findings generally fall short of providing clear answers to specific questions. However, they are often provide considerable insight into the types of details that future surveys should address with respect to various issues. Given this, perhaps the more important results are conclusions about how the findings of this survey, and the insights that they generate, can be used to develop more focused and definitive surveys of this type in the future.
External Shear in Quadruply Imaged Lens Systems
Creators: name: Holder, Gilbert P.

Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We use publicly available N-body simulations and semi-analytic models of galaxy formation to estimate the levels of external shear due to structure near the lens in gravitational lens systems. We also describe two selection effects, specific to four-image systems, that enhance the probability of observing systems to have higher external shear. Ignoring additional contributions from "cosmic shear" and assuming that lens galaxies are not significantly flattened, we find that the mean shear at the position of a quadruple lens galaxy is 0.11, the rms shear is roughly 0.15, and there is roughly a 45% likelihood of external shear greater than 0.1. This is much larger than previous estimates and in good agreement with typical measured external shear. The higher shear primarily stems from the tendency of early-type galaxies, which are the majority of lenses, to reside in overdense regions.

description: The composite optical beams being a result of superposition, are a promising way to study the orbital angular momentum and its effects. Their wide range of applications makes them attractive and easily available due to the growing interest in the Spatial Light Modulators (SLM). In this paper, we present a simple method for generating composite vortex patterns with high symmetry. Our method is simple, flexible and gives perfectly aligned beams, insensitive to mechanical vibrations. This method is based on the ability to split SLM cells between phase patterns that are to be superposed. This approach allows control of the intensity relation between those structures, enables their rotation and is capable to superpose more than two such structures. In this paper, we examine its ability to produce superposition of two optical vortices by presenting both theoretical and experimental results.

description: Ophioplexa gen. nov.
 Diagnosis. The disk covered with numerous small, uniform scales covered by a thin skin layer, not evident when dried. The radial shield and adradial genital plate are small and externally inconspicuous. The articulation surface of the radial shield is distinctly excavated ventrally, distally with a groove. The abradial genital plate is absent. The genital slits are small. The oral frame bears numerous oral papillae similar in shape to the cluster of the ventralmost teeth (apical papillae). Several adoral shield papillae, which do not differ considerably from the oral papillae, are placed around the second tentacle pore. The jaws are slightly elongated. The adradial sides of the jaws distally bear a few sharp straight folds. The dental plate is large with rounded sockets and irregular folds. The teeth are spiniform and numerous, ventralmost teeth of similar shape. The dorsal and ventral arm plates are well developed. The arm spine articulations are compressed transversally. Some proximal articulations may have a distinct nerve opening. The sigmoidal fold is absent. The arm spines are hollow, relatively short and flattened, not hooked distally. The vertebrae are distinctly keeled and with zygospondylous articulation.
 Etymology. Ophio - (after ophiuroid) and plexus (Latin, noun, feminine), braided, in current usage meaning also a complicated combination of elements in a system, in reference to an intricate relationship of the new genus combining traits of both ophiomyxids and ophiacanthids.
 Remarks. (see also under Discussion below). The new genus shows some similarities to the genus Ophiocymbium in the presence of a poorly developed adradial genital plate and radial shield, but possesses several important differences. The genus Ophiocymbium has distinct block-shaped distal oral papillae as adult and few apical papillae, whereas Ophioplexa gen. nov. is characterized by numerous spiniform oral papillae, both proximally and distally. The numerous apical papillae of Ophioplexa gen. nov. are placed in a dense cluster, whereas Ophiocymbium has only a few apical papillae. The arm spine articulations of Ophioplexa gen. nov. are dorso-ventrally compressed with distinct nerve and muscle openings, whereas Ophiocymbium has a typical rounded muscle opening, but the nerve opening, if conspicuous, has a different appearance. The dental plate of Ophioplexa gen. nov. has a remarkable appearance, with a combination of several articulations and numerous small openings (Fig. 55M–N), whereas the dental plate of Ophiocymbium has a few round openings and completely lacks articulation (Fig. 12E–H).

description: We present a general scheme for constructing the Poisson structure of super-integrable dynamical systems of which the rational Calogero-Moser system is one of the most interesting one. This dynamical system is $2N$ dimensional with $2N- 1$ first integrals and our construction yields $2N-1$ degenerate Poisson tensors that each admit $2(N-1)$ Casimirs. Our results are quite generally applicable to all super-integrable systems and form an alternative to the traditional bi-Hamiltonian approach.

This allows us to show under which conditions the BSSN system is, in a sense to be discussed, hyperbolic. This desirable property may account in part for the empirically observed better behavior of the BSSN formulation in numerical evolutions involving black holes.

description: High-dimensional prediction with multiple data types needs to account for potentially strong differences in predictive signal. Ridge regression is a simple model for high-dimensional data that has challenged the predictive performance of many more complex models and learners, and that allows inclusion of data type specific penalties. The largest challenge for multi-penalty ridge is to optimize these penalties efficiently in a cross-validation (CV) setting, in particular for GLM and Cox ridge regression, which require an additional estimation loop by iterative weighted least squares (IWLS). Our main contribution is a computationally very efficient formula for the multi-penalty, sample-weighted hat-matrix, as used in the IWLS algorithm. As a result, nearly all computations are in low-dimensional space, rendering a speed-up of several orders of magnitude. We developed a flexible framework that facilitates multiple types of response, unpenalized covariates, several performance criteria and repeated CV. Extensions to paired and preferential data types are included and illustrated on several cancer genomics survival prediction problems. Moreover, we present similar computational shortcuts for maximum marginal likelihood and Bayesian probit regression. The corresponding R-package, multiridge, serves as a versatile standalone tool, but also as a fast benchmark for other more complex models and multi-view learners.
3-D Interacting CFTs and Generalized Higgs Phenomenon in Higher Spin Theories on AdS

description: We study a duality, recently conjectured by Klebanov and Polyakov, between higher-spin theories on AdS_4 and O(N) vector models in 3-d. These theories are free in the UV and interacting in the IR. At the UV fixed point, the O(N) model has an infinite number of higher-spin conserved currents. In the IR, these currents are no longer conserved for spin s>2. In this paper, we show that the dual interpretation of this fact is that all fields of spin s>2 in AdS_4 become massive by a Higgs mechanism, that leaves the spin-2 field massless. We identify the Higgs field and show how it relates to the RG flow connecting the two CFTs, which is induced by a double trace deformation.

description: Evidences of the effects of unobserved heterogeneity in micro-econometric models are now pervasive in many applied economics fields. This article investigates this issue for agricultural production choice models. Farms’ and farmers’ unobserved heterogeneity can be accounted for in micro-econometric agricultural production choice models by relying on available modeling and inference tools. The random parameter (RP) framework allows achieving this goal in a fairly flexible way. This modeling framework has already been successfully used in numerous empirical studies covering many topics. It simply considers RP versions of standard models. Extensions of the Expectation-Maximization algorithms have been specifically developed in the computational statistics literature for estimating RP models. They appear to be well suited for large statistical models such as micro-econometric agricultural production choice models. The estimation of a RP multi-crop econometric model shows that unobserved heterogeneity matters in a sample of French farmers specialized in cash grain production covering a relatively small geographical area. The key parameters of this RP model significantly vary across farms. Simulation results obtained from the estimated RP model confirm that the sampled farmers’ choices respond heterogeneously to homogenous economic incentives. Ignoring this heterogeneity impacts both the distribution and the magnitude of the simulated effects.
Chiral instabilities & the onset of chiral turbulence in QED plasmas

description: We present a first principles study of chiral plasma instabilities and the onset of chiral turbulence in QED plasmas far from equilibrium. By performing classical-statistical lattice simulations of the microscopic theory, we show that the generation of strong helical magnetic fields from a helicity imbalance in the fermion sector proceeds via three distinct phases. During the initial linear instability regime the helicity imbalance of the fermion sector causes an exponential growth(damping) of magnetic field modes with right(left) handed polarization, for which we extract the characteristic growth (damping) rates. Secondary growth of unstable modes accelerates the helicity transfer from fermions to gauge fields and ultimately leads to the emergence of a self-similar scaling regime characteristic of decaying turbulence, where magnetic helicity is efficiently transferred to macroscopic length scales. Within this turbulent regime the evolution of magnetic helicity spectrum can be described by an infrared power-spectrum with spectral exponent $κ$ and dynamical scaling exponents $α,β$, which we determine from our simulations.

description: We analyze how a change in agricultural input price impacts the selection process and market shares in foreign markets for firms in the final agrifood good sector. To do so we develop a model with heterogeneous firms and intermediate good where input use is technologically constrained. We show that the effect of input price depends on labor productivity and fixed costs. Moreover, we show that a decrease in input price in all countries can decrease the probability to enter foreign markets, through export or horizontal foreign direct investment (HFDI). Finally, we show that the decrease of the intermediate good price always increases the share of HFDI relative to export, even if it can modify the HFDI-Export trade-off in favor of HFDI or export.

description: In this paper, the dilepton electromagnetic decays $χ_{cJ}(1P) \to J/ψe^+e^-$ and $χ_{cJ}(1P) \to Jψμ^+μ^-$, where $χ_{cJ}$ denotes $χ_{c0}$, $χ_{c1}$ and $χ_{c2}$, are calculated systematically in the improved Bethe-Salpeter method. The numerical results of decay widths and the invariant mass distributions of the final lepton pairs are given. The comparison is made with the recently measured experimental data of BESIII. It is shown that for the cases including $e^+e^-$, the gauge invariance is decisive and should be considered carefully. For the processes of $χ_{cJ}(1P) \to J/ψe^+e^-$, the branching fraction are: $\mathcal{B}[χ_{c0}(1P) \to J/ψe^+e^-]=1.06^{+0.16}_{-0.18} \times 10^{-4}$, $\mathcal{B}[χ_{c1}(1P) \to J/ψe^+e^-]=2.88^{+0.50}_{-0.53} \times 10^{-3}$, and $\mathcal{B}[χ_{c2}(1P) \to J/ψe^+e^-]=1.74^{+0.22}_{-0.21} \times 10^{-3}$. The calculated branching fractions of $χ_{cJ}(1P)\to J/ψμ^+μ^-$ channels are: $\mathcal{B}[χ_{c0}(1P) \to J/ψμ^+μ^-]=3.80^{+0.59}_{-0.64} \times 10^{-6}$, $\mathcal{B}[χ_{c1}(1P) \to J/ψμ^+μ^-]=2.04^{+0.36}_{-0.38} \times 10^{-4}$, and $\mathcal{B}[χ_{c2}(1P) \to J/ψμ^+μ^-]=1.66^{+0.19}_{-0.19} \times 10^{-4}$.

description: We present the results of bispectrum speckle interferometry of the B[e] star MWC 349A obtained with the SAO 6m telescope. Our diffraction-limited J-, H-, and K-band images (resolutions 43--74 mas) suggest the star is surrounded by a circumstellar disk seen almost edge-on. The observed visibility shape is consistent with a two-component elliptical disk model, probably corresponding to the gaseous and dusty components of the disk. We show that the classification of the object as a pre-main-sequence star or a young planetary nebula is problematic. An analysis of the uncertainties in the basic parameter determination lead us to the conclusion that MWC 349A is probably either a B[e] supergiant or a binary system, in which the B[e]-companion dominates the observed properties.

description: Between the two world wars, Australian artists developed a profound interest in the legacies of ancient Graeco-Roman art and incorporated its elements into their own artworks and important public commissions. Yet within academic studies, how ancient Graeco-Roman art and ideas were of influence upon Australian visual culture in the 1920s and thirties is largely underappreciated. This thesis aims to fill this absence in scholarship. It investigates the causes and uses of classical influences in Interwar Australian art as it appeared in three major subject areas: war memorials, pastoral landscapes, and the body as a mythological subject.

description: The purpose of this paper is to study the existence of weak solutions for some classes of one-parameter subelliptic gradient-type systems involving a Sobolev-Hardy potential defined on an unbounded domain $Ω_ψ$ of the Heisenberg group $\mathbb{H}^n=\mathbb{C}^n\times \mathbb{R}$ ($n\geq 1$) whose geometrical profile is determined by two real positive functions $ψ_1$ and $ψ_2$ that are bounded on bounded sets. The treated problems have a variational structure and thanks to this, we are able to prove the existence of an open interval $Λ\subset (0,\infty)$ such that, for every parameter $λ\in Λ$, the system has at least two nontrivial symmetric weak solutions that are uniformly bounded with respect to the Sobolev $HW^{1,2}_0$-norm. Moreover, the existence is stable under certain small subcritical perturbations of the nonlinear term. The main proof, crucially based on the Palais principle of symmetric criticality, is obtained by developing a group-theoretical procedure on the unitary group $\mathbb{U}(n)=U(n)\times\{1\}$ and by exploiting some compactness embedding results into Lebesgue spaces, recently proved for suitable $\mathbb{U}(n)$-invariant subspaces of the Folland-Stein space $HW^{1,2}_0(Ω_ψ)$. A key ingredient for our variational approach is a very general min-max argument valid for sufficiently smooth functionals defined on reflexive Banach spaces.

description: Humanity is facing an enormous challenge in managing water to secure adequate food production. By the middle of this century, the world’s population is projected to reach 9.1 billion, 34 percent higher than today. Nearly all of this increase will occur in developing countries. In order to respond to the expected demand of this larger, more urban and, on average, richer population, food production must increase by about 70% as estimated by the FAO. It is an enormous task because the required increase in food production to meet future needs will have to be achieved with fewer land and water resources. Food insecurity in Pakistan is a product of poverty and inadequate food availability. During the past two decades, 1987-2007, food poverty incidence in the country shows that about one-third of the households were living below the food poverty line and they were not meeting their nutritional requirements. The incidence of food poverty is higher in rural areas (35%), than in urban areas (26%). In Pakistan, irrigated agriculture is vital for future food security because it produces more than 90% of the total grain production. With the decreasing amounts of available water, the challenge of sustaining irrigated agriculture is increasing by the day. This paper reviews the situation in Pakistan and suggests pathways to sustain irrigated agriculture in order to meet future food requirements.

description: Sensors have revolutionized modern technology, with flexible sensors offering lightweight, adaptable integration across varied applications. However, challenges include limited response time and a restricted pressure range. This research utilized 3D printing to tackle these limitations. By using Poly-DiMethyl Siloxane (PDMS) porous structures, the sensor's response time improved, particularly for vibration monitoring. A specialized sensor, coated with graphene elastomer ink, showed adaptability to different strain rates, making it suitable for wearables and medical alerts. Another sensor using Carbon Black particles was ideal for constant pressure monitoring. Addressing pressure range issues, the study integrated flexible sensors into 3D printed shoe soles, aiding diabetic patient monitoring. This research enhances flexible sensor applications in various sectors.

description: We provide an analytic, microscopic analysis of extreme events in an adaptive population comprising competing agents (e.g. species, cells, traders, data-packets). Such large changes tend to dictate the long-term dynamical behaviour of many real-world systems in both the natural and social sciences. Our results reveal a taxonomy of extreme events, and provide a microscopic understanding as to their build-up and likely duration.

description: We study the production efficiency of teff in Ethiopia. Using a large cross-section of teff plots, we find that teff output could be increased by approximately 25 percent with the available inputs and technology through investments directed to improved gender-sensitive extension service and infrastructure development. The magnitude of technical inefficiency is robust to alternative functional form and various variable specifications. Community discussion groups and distance to the nearest agricultural co-operative are further shown to have a significant effect on technical efficiency. We conclude the paper by discussing the potential policy implications of our findings.

description: We have obtained deep optical, long-slit spectrophotometry of the Galactic HII regions M 17, NGC 3576 and of the Magellanic Cloud HII regions 30 Doradus, LMC N11B and SMC N66, recording the optical recombination lines (ORLs) of CII, NII and OII. Temperature-insensitive ORL C2+/O2+ and N2+/O2 ratios are obtained for all nebulae except SMC N66. The ORL C2+/O2+ ratios show remarkable agreement within each galactic system, while also being in agreement with the corresponding CEL ratios. For all five nebulae, the O2+/H+ abundance derived from multiple OII ORLs is found to be higher than the corresponding value derived from the strong [OIII] 4959, 5007A CELs, by factors of 1.8--2.7 for four of the nebulae. The LMC N11B nebula exhibits a more extreme discrepancy factor for the O2+ ion, ~5. Thus these HII regions exhibit ORL/CEL abundance discrepancy factors that are similar to those previously encountered amongst planetary nebulae. Our optical CEL O2+/H+ abundances agree to within 20-30 per cent with published O2+/H+ abundances that were obtained from observations of infrared fine-structure lines. Since the low excitation energies of the latter make them insensitive to variations about typical nebular temperatures, fluctuations in temperature are ruled out as the cause of the observed ORL/CEL O2+ abundance discrepancies. We present evidence that the observed OII ORLs from these HII regions originate from gas of very similar density (<3500 cm-3) to that emitting the observed heavy-element optical and infrared CELs, ruling out models that employ high-density ionized inclusions in order to explain the abundance discrepancy. We consider a scenario whereby much of the heavy-element ORL emission originates from cold (<=500 K) metal-rich ionized regions.

description: This paper measures the impact of the 1990 Clean Air Act Amendment on productivity and output of US coal-fired boilers. The Act led to power units adopting a number of different pollution abating strategies, one of which was an input change to lower SO2 emitting coal. A key feature is that each boiler is designed to burn a particular variety of coal, with significant deviations from the targeted coal characteristics resulting in productivity loss. The main innovation of the paper is to quantify the effect that switching to cleaner coal had on productivity and output. With data spanning over fifteen years, I incorporate the effect of this deviation directly into a production function to explicitly quantify the resulting productivity loss. Estimated output losses range from 0% to more than 6%, varying across regions, over time, and mainly depending on the proximity of generating units to low-sulfur sources.

description: Traditional monocular direct visual odometry (DVO) is one of the most famous methods to estimate the ego-motion of robots and map environments from images simultaneously. However, DVO heavily relies on high-quality images and accurate initial pose estimation during tracking. With the outstanding performance of deep learning, previous works have shown that deep neural networks can effectively learn 6-DoF (Degree of Freedom) poses between frames from monocular image sequences in the unsupervised manner. However, these unsupervised deep learning-based frameworks cannot accurately generate the full trajectory of a long monocular video because of the scale-inconsistency between each pose. To address this problem, we use several geometric constraints to improve the scale-consistency of the pose network, including improving the previous loss function and proposing a novel scale-to-trajectory constraint for unsupervised training. We call the pose network trained by the proposed novel constraint as TrajNet. In addition, a new DVO architecture, called deep direct sparse odometry (DDSO), is proposed to overcome the drawbacks of the previous direct sparse odometry (DSO) framework by embedding TrajNet. Extensive experiments on the KITTI dataset show that the proposed constraints can effectively improve the scale-consistency of TrajNet when compared with previous unsupervised monocular methods, and integration with TrajNet makes the initialization and tracking of DSO more robust and accurate.

description: Certified coffee production is an opportunity for the grower to differ his product. However, the number of certified producers is still relatively small. In order to contribute to the dissemination of accreditation among farmers, the objective of this study is to identify the factors that determine its adoption, based on a sample of certified and non-certified growers from the south of Minas Gerais, Brazil. Quantitative data were analyzed through logistic regression. Results showed that five variables were significant in explaining the certification adoption: grower’s age; role of coffee in family income; attending courses and events; computer use in the farm and crop yield. These results expand the existing knowledge about coffee certifications and can guide actions to increase the number of certified producers.

description: Road accident statistics are collected from information about personal injury road accidents and their consequent casualties, to a common national standard. The aim of collecting and publishing national road accident statistics is to inform public debate and to provide the basis for determining and monitoring effective road safety policies to reduce the road accident casualty toll. They are an essential requirement for monitoring targeted reductions in road accident casualties. The credible monitoring of targeted reductions requires that data are reported consistently and accurately, and both national and local government, and local reporting police forces, work closely to achieve a common reporting standard.

Users should note that for 1985-1991, and from 2002 onwards, the Vehicle Record file does not contain breath test data. This change has been made in order to protect confidentiality.

Data for 1985-1990 were deposited at the Archive at the beginning of 2006. Prior to this, the Archive only held the Road Accident Data series from 1991 onwards. No extra documentation was available for the 1985-1990 data, so users are advised to consult the documentation for the 1991 survey.

Further information about the Road Accident Data series and research based on it may be found on the government road accidents and safety statistics webpages.

Pd/Pt embedded CN monolayer as efficient catalysts for CO oxidation

description: Single atom catalysts (SACs) based on 2D materials are identified to be efficient in many catalytic reaction. In this work, the catalytic performance of Pd/Pt embedded planar carbon nitride (CN) for CO oxidation, has been investigated via spin$-$polarized density functional theory calculations. We find that Pd/Pt can be firmly anchored in the porous CN monolayer due to the strong hybridization between Pd/Pt-d orbitals and adjacent N-2p orbitals. The resulting high adsorption energy and large diffusion barrier of Pd/Pt, ensuring the remarkable stability of the catalyst Pd/Pt@CN during CO oxidation reaction. The three distinct CO reaction mechanisms, namely, Eley-Rideal (ER), Langmuir-Hinshelwood (LH), and Tri-molecular Eley-Rideal (TER), are taken into consideration comparatively. Intriguingly, the oxidation reaction on Pd@CN prefers to proceed through the less common TER mechanism, where two CO molecules and one O2 molecule need to cross a small reaction barrier of 0.48 eV, and finally dissociate into two CO2 molecules. However, the LH mechanism is the most relevant one on Pt@CN with a rate-limiting reaction barrier of 0.68 eV. Moreover, the origin of SAC's reactivity enhancement is the electronic "acceptance$-$donation" interaction caused by orbital hybridization between Pd/Pt and preadsorbed O2/CO. Our findings are expected to widen the catalytic application of carbon based 2D materials.

description: Interdependence between first and second moments of producer and consumer wheat prices in Slovenia is assessed. A joint estimation of a threshold vector error and MGARCH models with exogenous variables in the conditional mean and conditional covariance equations are applied for such purpose. Results indicate that price-level adjustments mainly favor retailers by increasing their marketing margins. Important second-moment interactions are also identified. Increases in international wheat stocks reduce producer prices, while higher interest rates increase their instability.
