description: We report the electronic properties of single crystals of candidate nodal-line semimetal CaAgP. The transport properties of CaAgP are understood within the framework of a hole-doped nodal-line semimetal. In contrast, Pd-doped CaAgP shows a drastic increase of magnetoresistance at low magnetic fields and a strong decrease of electrical resistivity at low temperatures probably due to weak antilocalization. Hall conductivity data indicated that the Pd-doped CaAgP has not only hole carriers induced by the Pd doping, but also high-mobility electron carriers in proximity of the Dirac point. Electrical resistivity of Pd-doped CaAgP also showed a superconducting transition with onset temperature of 1.7-1.8 K.

description: A set of electron-correlation energies as large as 10 eV have been measured for a magnetic 2ML Fefilm deposited on Ag(001). By exploiting the spin selectivity in angle-resolved Auger-photoelectroncoincidence spectroscopy and the Cini-Sawatzky theory, the core-valence-valence Auger spectrumof a spin-polarized system have been resolved: correlation energies have been determined for eachindividual combination of the two holes created in the four sub-bands involved in the decay: majorityand minority spin, as well asegandt2g. The energy difference between final states with paralleland antiparallel spin of the two emitted electrons is ascribed to the spin-flip energy for the final ionstate, thus disentangling the contributions of Coulomb and exchange interactions.

description: Farm-level trade-offs between development objectives are analysed using a three-stage methodological design. Firstly, a typology of arming systems is devised, using data from a farm-level survey and the methods of principal components analysis and cluster analysis. Five farm types are described that characterize current production practices in two regions in the Philippines. Secondly, a set of sustainability indicators are measured for each of the five farm types. Finally, the sustainability indicator results are analysed in a participatory multi-criteria decision-making model using weights established during a series of focus groups with stakeholders in the study regions. Very large farms perform particularly badly in these analyses, and the optimal farming system varies across social groups. The implications for the management of the sector are discussed, particularly in relation to aquaculture’s continued exemption from agrarian reform legislation.

description: Interest in Management Intensive Grazing (MIG) of dairy cattle has increased during the last 2 decades. Most dairy producers utilizing MIG were former confinement or non-intensive pasture operations while the others started their operation with MIG. While research publications tout the financial and other benefits of MIG, often comparing them to non-MIG dairies, and anecdotal evidence in popular farm press has shown MIG in a favorable light, comparing a MIG dairy farm to itself before and after the management switch has not been a subject of research scrutiny. Knowing the potential impact of a switch to MIG prior to making a management decision to do so would be a significant piece of information for a dairy farm to understand if contemplating such a management change. Which farms are candidates for success following a switch? What changes in labor, cost of production, and herd health might be expected? These and other questions were investigated by examining 29 MIG dairy farms in Michigan. These farms experienced similar milk production levels per cow, reduced feed and hired labor cost significantly, reduced the acres of row crops grown, and experienced improved herd health resulting in much lower herd health costs. They did not build farm acres, but rather grew cattle numbers and improved management of pasture forage. Research work remains to be done that will more accurately measure true economic progress and further find management techniques that prove successful for MIG farms.

description: Data from a national telephone survey of working-aged adults in the continental US is combined with US Census 2000 data to explore the determinants of attachment to place and time preferences for jobs, natural amenities, and financial assets. Five regions in the US were delineated so that regional differences in the determinants of the dependent variables of interest could be parsed out. The regions are the Great Plains, Borderlands, Appalachia, the Plantation Belt, and the rest of the continental US. The first essay that explores time preferences for jobs, natural amenities, and money. Each was embedded with a ten percent rate of return. In aggregate, the nation as a whole demonstrated that the discount rate for jobs, natural amenities, and financial assets were each very different. The second essay explores the determinants of attachment to place by asking respondents how much money it would take to convince them to move to another community. Regional differences were detected both for time preferences and attachment to place. In addition to the independent variables classically used to explore our dependent variables of interest, these regional variables and their interactive expansions were observed to have a significant effect.

description: This study used the contingent valuation method to shed light on public preferences on the multifunctional roles of the U.S. agriculture and to present a holistic estimate of the economic value of the nonmarket goods and services of the U.S. agriculture. Fishbein’s model of reasoned behavior and mediation hypothesis were combined to model the relationship between WTP (behavioral intentions) and sets of explanatory variables including attitudes, perceived attributes (about family farms, farmland preservation programs, government involvement in agricultural markets, and ecological state of our world), and socio-demographic profiles. The estimated mean WTP was $515 per taxpayer annually. Aggregating individual WTPs across the U.S. taxpayers above 20 years old produces $105 billion, representing a crude estimate of the economic value that the U.S. consumers place on the multifunctional roles of the U.S. agriculture.

description: A liquid can exist under conditions of thermodynamic stability or metastability within boundaries defined by the liquid-gas spinodal and the glass transition line. The relationship between these boundaries has been investigated previously using computer simulations, the energy landscape formalism, and simplified model calculations. We calculate these stability boundaries semi-analytically for a model glass forming liquid, employing accurate liquid state theory and a first-principles approach to the glass transition. These boundaries intersect at a finite temperature, consistent with previous simulation-based studies.

description: The observation of chiral-induced spin selectivity (CISS) in biological molecules still awaits a full theoretical explanation. In a recent Rapid Communication, Varela et al. [Phys. Rev. B 101, 241410(R) (2020)] presented a model for electron transport in biological molecules by tunneling in the presence of spin-orbit interactions. They then claimed that their model produces a strong spin asymmetry due to the intrinsic atomic spin-orbit strength. As their Hamiltonian is time-reversal symmetric, this result contradicts a theorem by Bardarson [J. Phys. A: Math. Theor. 41, 405203 (2008)], which states that such a Hamiltonian cannot generate a spin asymmetry for tunneling between two terminals (in which there are only a spin-up and a spin-down channels). Here we solve the model proposed by Varela et al. and show that it does not yield any spin asymmetry, and therefore cannot explain the observed CISS effect.

The effect of shale composition on the gas sorption potential of organic-rich mudrocks in the Western Canadian sedimentary basin
Creators: name: Ramos, Sharleen
Publisher: name: University of British Columbia
Year: 2009

description: The gas sorption capacity of six organic-rich mudstones found throughout the Phanerozoic in the Western Canadian Sedimentary Basin has been measured through 66 high-pressure methane sorption isotherms at 30°C. The shales vary in total organic carbon and maturity (Tmax). Variations of gas sorption potential with shale composition, organic matter abundance, kerogen types, composition, geochemistry, and maturity have been investigated. For the combined data set, the amount of total organic carbon is strongly related to methane sorption capacity (r² = 0.78). Organic-rich shales show better correlation between total organic carbon and methane sorption capacity and higher sorption capacities than organic-lean shales. Low-TOC shales are influenced by mineralogical differences (more clay for sorption) and pore/moisture/maturity relationships. Gas sorption capacity increases with maturation because there is decreased competition of organic (eg. vitrinite) and rnineral matter (eg. clays) sites for sorption from moisture because of reduced moisture contents with depth. Increased microporosity of the organic matter is also associated with higher maturity shales as seen by the flattening of the isotherm curve. Methane sorption capacity and TOC abundance varies with organic matter type, nature, HI, kerogen isotopic composition and depositional environment. Difficulties exist when attempting to determine if methane sorption capacity varies with organic matter composition. However, it is noted that isolating samples of similar TOC and maturity, samples with more vitrinite (Type III) have more sorption capacity. The shales sampled in this study vary in inorganic and organic compositions, organic matter abundances, kerogen types, maturity, porosity, and permeability, which vary vertically and laterally throughout a shale sequence. Therefore, the spatial variability of these variables should be considered in exploration programs for natural gas from shale strata. Future work on gas shale targets includes detailed sequence stratigraphy, paleoenvironmental analysis, and structural analysis. Core, well log signatures (eg. gamma ray, density, sonic and resistivity), and sorption data can be correlated with total organic carbon and compositional variations (using mineralogy and kerogen isotopes) to identify varying composition and gas potential throughout a target. Kerogen can be isolated to measure differences in sorption of varying organic matter compositions. The porosity available to methane (free gas porosity) and pore structures also should be researched.

Similarity of Initial States in A+A and p+p Collisions in Constituent Quarks Framework
Creators: name: Nouicer, Rachid
Publisher: name: arXiv
Year: 2005
Subjects: subject: Nuclear Experiment (nucl-ex)
subject: FOS: Physical sciences

description: The multiparticle production results from A+A and p(\bar{p})+p collisions have been compared based on the number of nucleon participants and the number of constituent quark (parton) participants. In both normalizations, we observe that the charged particle densities in Au+Au and Cu+Cu collisions are similar for both \sqrt{s_{NN}} = 62.4 and 200 GeV. This implies that in symmetric nucleus-nucleus collisions the charged particle density does not depend on the size of the two colliding nuclei but only on the collision energy. In the nucleon participants framework, the particle density at mid-rapidity as well as in the limiting fragmentation region from A+A collisions are higher than those of p(\bar{p})+p collisions at the same energy. Also the integrated total charged particle in A+A collisions as a function of number nucleon participants is higher than p(\bar{p})+p collisions at the same energy indicating that there is no smooth transition between peripheral A+A and nucleon-nucleon collisions. However, when the comparison is made in the constituent quarks framework, A+A and p(\bar{p})+p collisions exhibit a striking degree of agreement. The observations presented in this paper imply that the number of constituent quark pairs participating in the collision controls the particle production. One may therefore conjecture that the initial states A+A and p+p collisions are similar when the partonic considerations are used in normalization. Another interesting result is that there is an overall factorization of dN/dηshapes as a function of collision centrality between Au+Au and Cu+Cu collisions at the same energy, \sqrt{s_{NN}} = 200 GeV.

description: The Linux kernel is mostly designed for multi-programed environments, but high-performance applications have other requirements. Such applications are run standalone, and usually rely on runtime systems to distribute the application's workload on worker threads, one per core. However, due to current OSes limitations, it is not feasible to track whether workers are actually running or blocked due to, for instance, a requested resource. For I/O intensive applications, this leads to a significant performance degradation given that the core of a blocked thread becomes idle until it is able to run again. In this paper, we present the proof-of-concept of a Linux kernel extension denoted User-Monitored Threads (UMT) which tackles this problem. Our extension allows a user-space process to be notified of when the selected threads become blocked or unblocked, making it possible for a runtime to schedule additional work on the idle core. We implemented the extension on the Linux Kernel 5.1 and adapted the Nanos6 runtime of the OmpSs-2 programming model to take advantage of it. The whole prototype was tested on two applications which, on the tested hardware and the appropriate conditions, reported speedups of almost 2x.

description: While many approaches exist in the literature to learn low-dimensional representations for data collections in multiple modalities, the generalizability of multi-modal nonlinear embeddings to previously unseen data is a rather overlooked subject. In this work, we first present a theoretical analysis of learning multi-modal nonlinear embeddings in a supervised setting. Our performance bounds indicate that for successful generalization in multi-modal classification and retrieval problems, the regularity of the interpolation functions extending the embedding to the whole data space is as important as the between-class separation and cross-modal alignment criteria. We then propose a multi-modal nonlinear representation learning algorithm that is motivated by these theoretical findings, where the embeddings of the training samples are optimized jointly with the Lipschitz regularity of the interpolators. Experimental comparison to recent multi-modal and single-modal learning algorithms suggests that the proposed method yields promising performance in multi-modal image classification and cross-modal image-text retrieval applications.

We examine the effects of a spatially uniform, but time-varying electric field (ignoring magnetic-field effects). The electronic Green's functions, Wigner density of states, and time-varying current are all determined and analyzed. We study both constant and pulsed electric fields, focusing on the transient response region. These noninteracting Green's functions are an important input into nonequilibrium dynamical mean field theory for the nonlinear response of strongly correlated electrons.

description: We show how to prepare a variety of cavity field states for multiple cavities. The state preparation technique used is related to the method of stimulated adiabatic Raman passage or STIRAP. The cavity modes are coupled by atoms, making it possible to transfer an arbitrary cavity field state from one cavity to another, and also to prepare non-trivial cavity field states. In particular, we show how to prepare entangled states of two or more cavities, such as an EPR state and a W state, as well as various entangled superpositions of coherent states in different cavities, including Schrodinger cat states. The theoretical considerations are supported by numerical simulations.

Renormalization group equations in a model of generalized hidden local symmetry and restoration of chiral symmetry

description: We study possible restoration patterns of chiral symmetry in a generalized hidden local symmetry model, which is a low energy effective theory of QCD including pseudo-scalar, vector and axial-vector mesons. We derive Wilsonian renormalization group equations and analyze the running couplings and their fixed points at the chiral restoration point. We find three types of the chiral restoration, which are classified as the standard, vector manifestation and intermediate scenarios, respectively. It turns out that the rho and A_1 meson become massless and their decay into pion is suppressed in all the restoration patterns. The each restoration scenario violates or fulfills the vector meson dominance at the critical point in a different manner, which may reflect on the contributions from the pion to the dilepton spectrum.

description: We exhibit a one-parameter family of regular supersymmetric solutions of type IIB theory that interpolates between Klebanov-Strassler (KS) and Maldacena-Nunez (MN). The solution is obtained by applying the supersymmetry conditions for SU(3)-structure manifolds to an interpolating ansatz proposed by Papadopoulos and Tseytlin. Other than at the KS point, the family does not have a conformally-Ricci-flat metric, neither it has self-dual three-form flux. Nevertheless, the asymptotic IR and UV are that of KS troughout the family, except for the extremal value of the interpolating parameter where the UV solution drastically changes to MN. This one-parameter family of solutions is interpreted as the dual of the baryonic branch of gauge theory, confirming the expecation that the KS solution corresponds to a particular symmetric point in the branch.

description: In this paper, by applying a Computable General Equilibrium model for Western Australia (called WAG), the impact of the 2002 dry season on the State’s wider economy is quantitatively analysed. An estimate of 40 percent loss in the production of five major groups of agricultural commodities is simulated into the model. The model results show that the State’s economy-wide total production declines by 2.3 percent. In 2001-02 dollar terms this production decline is worth more than $2.5 billion. The gross state product (GSP) for WA declines by more than one percent. The total value of the State’s exports and employment decline by 5.2 and 1.7 percent respectively.

description: Cyber defence is one side of a dynamic and ever-evolving confrontationwith attackers who seek to exploit weaknesses and cause unintended behaviour in digital systems. Historically both attackers and defenders have relied on human creativity and intellect to outdo one another,learning from each other’s tactics in a competitive, emergent,ad hoccurriculum. Modern cyber combatants increasingly rely on a variety ofautomated tools, machine learning; and perhaps more surprisingly, gameplaying in the pursuit of their goals. Whilst autonomous agents based on deep reinforcement learning have made tremendous breakthroughs playing complex strategy games such as Go, StarCraft, and Stratego,comparatively little progress has been witnessed in cyber defence gamesand the real-world problems they relate to. We highlight the current state of autonomous agents in cyber defence, presage their considerable future potential, and identify key research challenges both near and far.

We employ Choice Modeling to quantify the welfare change associated with the change in the levels of these attributes for a sample of Japanese consumers taken in December 2000. We found that consumers have a positive perception of the HACCP label, the Eco-milk label, and the freshness of the milk.

description: This paper analyses the impact of quality based labelling on product prices, factor allocation and the resulting effects on producers within the context of an international trading system. A general equilibrium model, calibrated to 1998 data, describes United States and European Union labelling regimes for genetically modified agricultural products. The results indicate that the labelling choice of trade partners have large distributive impacts within national economies, as well as across countries and highlight the importance of using general equilibrium framework to understand the system wide impacts of labelling policies that differentiate products based upon quality characteristics. These results are essential for policy makers seeking to understand the global and domestic economic implications of environmental labelling systems.

description: The development of genetically modified (GM) agricultural products requires new policies to manage potential food safety and environmental risks. The policy positions taken to date on GM foods by the United States and the European Union are very different. The US has few restrictions on production and trade in GM food products and no costly labelling requirements, whereas the EU has close to a ban on the production and importation of GM foods. This paper seeks to explain (a) why both the US and EU policies are extreme in the light of the uncertainty about the risks associated with GM foods, (b) what their consequences are for income distribution and trade in farm products, and (c) what it means for the GM policies and economic welfare of people in other (particularly developing) countries. In this paper we use the GTAP global economy wide model to estimate the extent of the trade, national welfare and income distributional effects of the actual policy choices of the US and the EU as compared with what they would be if GM products were adopted with less-distortionary GM policies. The distributional effects are used to also shed light on why the US and EU have adopted such different sub-optimal GM policies.

description: Entangled-photon coincidence imaging is a method to nonlocally image an object by transmitting a pair of entangled photons through the object and a reference optical system, respectively. The image of the object can be extracted from the coincidence rate of these two photons. From a classical perspective, the image is proportional to the fourth-order correlation function of the wave field. Using classical statistical optics, we study a particular aspect of coincidence imaging with incoherent sources. As an application, we give a proposal to realize lensless Fourier-transform imaging, and discuss its applicability in x-ray diffraction.

description: The paper describes a study of canal and supplemental ground water used by 544 farmers for wheat crop in the Rechna Doab catchment of Pakistan. The main objective was to assess the on-farm financial gains through conjunctive water use. For econometric analysis, a linear relationship between the wheat production and different determinant variables was assumed. The results highlighted the problem of increased use of tubewells water in the saline zones that had resulted in the deterioration of the groundwater quality and led to the problem of permanent upconing of saline groundwater. Conjunctive water management increased the farm income by about Rs. 1000 and 5000 per hectare compared to only using the canal and tubewell water, respectively The results of financial analysis show that the net-gains were 30 percent higher on the farms using conjunctive water management as compared to the farms using only tubewell irrigation.

description: The Fluctuation Relation (FR) is an asymptotic result on the distribution of certain observables averaged over time intervals T as T goes to infinity and it is a generalization of the fluctuation--dissipation theorem to far from equilibrium systems in a steady state which reduces to the usual Green-Kubo (GK) relation in the limit of small external non conservative forces. FR is a theorem for smooth uniformly hyperbolic systems, and it is assumed to be true in all dissipative ``chaotic enough'' systems in a steady state. In this paper we develop a theory of finite time corrections to FR, needed to compare the asymptotic prediction of FR with numerical observations, which necessarily involve fluctuations of observables averaged over finite time intervals T. We perform a numerical test of FR in two cases in which non Gaussian fluctuations are observable while GK does not apply and we get a non trivial verification of FR that is independent of and different from linear response theory. Our results are compatible with the theory of finite time corrections to FR, while FR would be observably violated, well within the precision of our experiments, if such corrections were neglected.

description: Deep learning (DL) has been applied extensively in many computational imaging problems, often leading to superior performance over traditional iterative approaches. However, two important questions remain largely unanswered: first, how well can the trained neural network generalize to objects very different from the ones in training? This is particularly important in practice, since large-scale annotated examples similar to those of interest are often not available during training. Second, has the trained neural network learnt the underlying (inverse) physics model, or has it merely done something trivial, such as memorizing the examples or point-wise pattern matching? This pertains to the interpretability of machine-learning based algorithms. In this work, we use the Phase Extraction Neural Network (PhENN), a deep neural network (DNN) for quantitative phase retrieval in a lensless phase imaging system as the standard platform and show that the two questions are related and share a common crux: the choice of the training examples. Moreover, we connect the strength of the regularization effect imposed by a training set to the training process with the Shannon entropy of images in the dataset. That is, the higher the entropy of the training images, the weaker the regularization effect can be imposed. We also discover that weaker regularization effect leads to better learning of the underlying propagation model, i.e. the weak object transfer function, applicable for weakly scattering objects under the weak object approximation. Finally, simulation and experimental results show that better cross-domain generalization performance can be achieved if DNN is trained on a higher-entropy database, e.g. the ImageNet, than if the same DNN is trained on a lower-entropy database, e.g. MNIST, as the former allows the underlying physics model be learned better than the latter.

China’s WTO Accession and Regional Economies

description: Along with the rapid economic growth since China undertook economic reform in 1978, the income gap among Chinese regions has widened. Using CERD, a computable general equilibrium model of the Chinese economy with regional details, this paper investigates the impact of China’s accession to the World Trade Organisation on regional development and finds that, although all regions will gain from the accession, the trend of a widening gap among regions will be reinforced rather than eased. Specifically, the eastern coastal region gains more than the inland regions. The result is robust no matter whether the change in trade balance is left free or fixed, although the scenario with zero change in the trade balance generates a lower overall welfare gain and an even worse regional disparity. A retreat from WTO commitments in tariff cuts in agriculture reduces welfare gains, but could to some degree ameliorate the worsening inequality between rural and urban households and between coastal and inland regions. However, this analysis incorporates only WTO commitments on tariff cuts and does not include commitments on non-tariff barriers. Moreover, it does not model other domestic reforms that may be adopted to offset the adjustment costs of the WTO commitments.

description: This paper investigates the impact of an expansion in agricultural processing on the Western Australian economy by modifying and applying a Computable General Equilibrium (CGE) economic model of Western Australia (called WAM). WAM was used to simulate the effects of a $1 million expansion in eight agricultural processing industries. The results show that there is a range of positive impacts from agricultural processing. On average, a $1 million expansion in agricultural processing is estimated to increase the State’s GSP (Gross State Product) by $649,000, and total output by $1.9 million. The expansion of the Wine and spirits industry is estimated to have the largest impact while the Textile fibres, yarns and woven fabrics industry has the smallest impact on the Western Australian economy.

description: Deep learning and convolutional neural networks (CNNs) have made progress in polarimetric synthetic aperture radar (PolSAR) image classification over the past few years. However, a crucial issue has not been addressed, i.e., the requirement of CNNs for abundant labeled samples versus the insufficient human annotations of PolSAR images. It is well-known that following the supervised learning paradigm may lead to the overfitting of training data, and the lack of supervision information of PolSAR images undoubtedly aggravates this problem, which greatly affects the generalization performance of CNN-based classifiers in large-scale applications. To handle this problem, in this paper, learning transferrable representations from unlabeled PolSAR data through convolutional architectures is explored for the first time. Specifically, a PolSAR-tailored contrastive learning network (PCLNet) is proposed for unsupervised deep PolSAR representation learning and few-shot classification. Different from the utilization of optical processing methods, a diversity stimulation mechanism is constructed to narrow the application gap between optics and PolSAR. Beyond the conventional supervised methods, PCLNet develops an unsupervised pre-training phase based on the proxy objective of instance discrimination to learn useful representations from unlabeled PolSAR data. The acquired representations are transferred to the downstream task, i.e., few-shot PolSAR classification. Experiments on two widely-used PolSAR benchmark datasets confirm the validity of PCLNet. Besides, this work may enlighten how to efficiently utilize the massive unlabeled PolSAR data to alleviate the greedy demands of CNN-based methods for human annotations.
