S-duality and loop operators in canonical formalism

description: We study the gauge invariant 't Hooft operator in canonical formalism for Yang-Mills theory as well as the $\mathcal{N} =4 $ super-Yang-Mills theory with the gauge group $ U(N) $. It is shown that the spectrum of the 't Hooft operator labeled by the arbitrary irreducible representation of the gauge group is the same as the spectrum of the Wilson operator labeled by the same representation. So it is possible to construct a unitary operator $ S $ making the two kinds of loop operators transformed into each other. S-duality transformation could be realized by the operator $ S $. We compute the supersymmetry variations of the loop operators with the fermionic couplings turned off. The result is consistent with the expectation that the action of $ S $ should make supercharges transform with a $ U(1)_{Y} $ phase.

Spontaneous parametric down-conversion induced by optomechanical gradient forces in nanophotonic waveguides

description: Optomechanical gradient forces arise from evanescent fields of guided waves in parallel photonic waveguides. When designed to be of attractive nature, they increase exponentially as the gap between the waveguides decreases. Moreover, the amplitude of the gradient force can be well controlled due to its linear dependence on the input laser power. Here, we propose to exploit the intrinsic nonlinear nature of the optomechanical gradient force to induce a tunable 3-wave coupling between the fundamental modes of two doubly clamped nanophotonic beams. For one of the beams having half the width of the other beam, the 1:2 internal resonance between the fundamental modes supports degenerate spontaneous parametric down-conversion (SPDC). We theoretically explore the main feature of the dissipative phase diagram of the underlying degenerate parametric oscillator model to show that the critical point of the SPDC occurs at parameters which are well in reach of state-of-the-art experiments.

description: We report the first detection of X-ray emission associated with the Homunculus Nebula which surrounds the supermassive star Eta Carinae. The emission is characterized by a temperature in excess of 100 MK, and is consistent with scattering of the time-delayed X-ray flux associated with the star. The nebular emission is bright in the northwestern lobe and near the central regions of the Homunculus, and fainter in the southeastern lobe. We also report the detection of an unusually broad Fe K fluorescent line, which may indicate fluorescent scattering off the wind of a companion star or some other high velocity outflow. The X-ray Homunculus is the nearest member of the small class of Galactic X-ray reflection nebulae, and the only one in which both the emitting and reflecting sources are distinguishable.

description: The knowledge of potentially druggable binding sites on proteins is an important preliminary step towards the discovery of novel drugs. The computational prediction of such areas can be boosted by following the recent major advances in the deep learning field and by exploiting the increasing availability of proper data. In this paper, a novel computational method for the prediction of potential binding sites is proposed, called DeepSurf. DeepSurf combines a surface-based representation, where a number of 3D voxelized grids are placed on the protein's surface, with state-of-the-art deep learning architectures. After being trained on the large database of scPDB, DeepSurf demonstrates superior results on three diverse testing datasets, by surpassing all its main deep learning-based competitors, while attaining competitive performance to a set of traditional non-data-driven approaches.

description: The homology of Kontsevich's commutative graph complex parameterizes finite type invariants of odd dimensional manifolds. This {\it graph homology} is also the twisted homology of Outer Space modulo its boundary, so gives a nice point of contact between geometric group theory and quantum topology. In this paper we give two different proofs (one algebraic, one geometric) that the commutative graph complex is quasi-isomorphic to the quotient complex obtained by modding out by graphs with cut vertices. This quotient complex has the advantage of being smaller and hence more practical for computations. In addition, it supports a Lie bialgebra structure coming from a bracket and cobracket we defined in a previous paper. As an application, we compute the rational homology groups of the commutative graph complex up to rank 7.

title: Distal transcriptional activators of the myelin basic protein gene in oligodendrocytes and Schwann cells
Creators: name: Taveggia, Carla
Publisher: name: The Open University
Year: 2002

description: Myelin is a multilamellar sheath that wraps the axons in the Central Nervous System (CNS) and in the Peripheral Nervous System (PNS). It is required for normal development, axonal health and to facilitate impulse conduction. MBP, one of the major myelin proteins, is synthesised by both oligodendrocytes (OL) in CNS and Schwann cells (SC) in PNS. Its synthesis is regulated primarily at the transcriptional level. MBP transcription is activated as a part of a program of coordinate myelin gene expression during development, overlapping but specific in OL as compared to SC. The nuclear proteins that bind to the MBP promoter are largely unidentified. In vitro and in vivo studies show that activation of the MBP proximal promoter requires different DNA binding sites and proteins in OL as compared to SC. Recently, transgenic mice studies identified a SC enhancer (SCE) located 9.0Kb upstream of the transcriptional start site of MBP. In this work, we compared MBP transcription mechanisms in OL and SC. Transient transfection analyses, in primary cultures of OL and SC, confirm the importance of SCE, and suggest that SCE is an activator in both cell types, but it is an enhancer only in SC. Biochemical analyses show that there are regions differentially protected by SC and OL nuclear extracts that can account for differential function. Analysis of internal deletions and transversion mutations of SCE suggests that multiple cis-acting elements cooperate to produce activation. Analyses of stably transfected SC show that chromatin upregulates SCE activation at least three fold. Co-culture of these stably transfected SC and dorsal root ganglia neurons reveal that axons markedly activate SCE, by at least two orders of magnitude. These results describe a model in which to analyse SCE biochemistry and function and identify trans-acting signals from axons that regulate MBP transcription in SC.

description: This report provides a detailed description of the structural equations and their statistical attributes in the current version of the Food and Agricultural Policy Simulator (FAPSIM). FAPSIM is an annual econometric model of the U.S. agricultural sector. It estimates a simultaneous price-quantity equilibrium solution for a set of individual commodity models developed for beef, pork, dairy, chickens, eggs, turkeys, corn, oats, barley, grain sorghum, wheat, soybeans, and cotton. It also endogenously estimates farm production expenses, cash receipts, net farm income, Government deficiency and reserve storage payments, consumer price indexes for food products, and farmer participation in Government commodity programs.

description: This paper reexamines four econometric models of the U.S. farmland market to test their validity over different and more recent time periods. Updating these models appears not to be fruitful. If econometric analysis is to play a role in analysis of the farmland market, it will probably be effective only in local areas where productive factors and responses to them are reasonably homogeneous, rather than within a national aggregated market for U.S. farmland.

description: This study simulates the consequences of replacing the competitive market for wheat and feed grains in the United States with a producer marketing board daich practices price discrimination. A U.S. producer board for wheat and feed ;rains would increase prices in the nonfeed and export markets by reducing sales in those markets. Further, board carry-out stocks would rise, while prices in lonboard markets would fall to the loan rate. U.S. growers would receive wind- fall rents, most of which would be income transfers from U.S. consumers. The Rifted States would receive a monopoly rent from foreign consumers. The board policy would support foreign producers through windfall gains. Finally, the board's operation would reduce the variability in grain prices.

description: Quantum annealers require accurate control and optimized operation schemes to reduce noise levels, in order to eventually demonstrate a computational advantage over classical algorithms. We study a high coherence four-junction capacitively shunted flux qubit (CSFQ), using dispersive measurements to extract system parameters and model the device. Josephson junction asymmetry inherent to the device causes a deleterious nonlinear cross-talk when annealing the qubit. We implement a nonlinear annealing path to correct the asymmetry in-situ, resulting in a substantial increase in the probability of the qubit being in the correct state given an applied flux bias. We also confirm the multi-level structure of our CSFQ circuit model by annealing it through small spectral gaps and observing quantum signatures of energy level crossings. Our results demonstrate an anneal-path correction scheme designed and implemented to improve control accuracy for high-coherence and high-control quantum annealers, which leads to an enhancement of success probability in annealing protocols.

description: The United States has the largest food manufacturing sector of any market economy of the world. The number of food manufacturers declined by 52 percent between 1974 and 1977. On average, the top four firms control over half of sales in processed-foods product classes; this concentration rose by 10 percent between 1958 and 1977. Product diversification has accelerated. Total food and beverage advertising and sales promotion expenditures ranged between $9 billion and $14 billion in 1979. These elements of market organization affect foodindustry economic performance: profit margins, manufacturers' prices, and technological change. About half of the food industries exhibit significant performance problems.

description: Given a vector bundle of arbitrary rank with ample determinant line bundle on a projective manifold, we propose a new elliptic system of differential equations of Hermitian-Yang-Mills type for the curvature tensor. The system is designed so that solutions provide Hermitian metrics with positive curvature in the sense of Griffiths-and even in the dual Nakano sense. As a consequence, if an existence result could be obtained for every ample vector bundle, the Griffiths conjecture on the equivalence between ampleness and positivity of vector bundles would be settled.

The entire land area of the country is broadly classed as cropland, grassland pasture and range,. forest land, special-use areas, and other land. Numerous subclasses reflect component agricultural and nonagricultural uses.
A general theory of comparison of quantum channels (and beyond)
Creators: name: Jenčová, Anna
Publisher: name: arXiv
Year: 2020
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We present a general theory of comparison of quantum channels, concerning with the question of simulability or approximate simulability of a given quantum channel by allowed transformations of another given channel. We introduce a modification of conditional min-entropies, with respect to the set F of allowed transformations, and show that under some conditions on F, these quantities characterize approximate simulability. If F is the set of free superchannels in a quantum resource theory of processes, the modified conditional min-entropies form a complete set of resource monotones. If the transformations in F consist of a preprocessing and a postprocessing of specified forms, approximate simulability is also characterized in terms of success probabilities in certain guessing games, where a preprocessing of a given form can be chosen and the measurements are restricted. These results are applied to several specific cases of simulability of quantum channels, including postprocessings, preprocessings and processing of bipartite channels by LOCC superchannels and by partial superchannels, as well as simulability of sets of quantum measurements. These questions are first studied in a general setting that is an extension of the framework of general probabilistic theories (GPT), suitable for dealing with channels. Here we prove a general theorem that shows that approximate simulability can be characterized by comparing outcome probabilities in certain tests. This result is inspired by the classical Le Cam randomization criterion for statistical experiments and contains its finite dimensional version as a special case.
description: 32 pages, comments welcome. A part of the paper was presented at the Algebraic and Statistical ways into Quantum Resource Theories workshop at BIRS in July 2019. Extended and revised, the case of LOCC superchannels added

description: Recent reforms have increased the social security tax burden on farmers and other self-employed workers. Some farmers are able to reduce their social security taxes by shifting their savings from farm to nonfarm investments, adjusting their use of debt, renting farmland to and from others, changing their hog- and cattle-raising practices, and incorporating their farm businesses. Each of these tax reduction methods can result in a misuse or misallocation of resources. Economic efficiency could be improved by changing the social security tax structure to eliminate existing incentives for the use of these tax-saving but inefficient business practices.
The two-dimensional magnetohydrodynamic Kelvin-Helmholtz instability: compressibility and large-scale coalescence effects

Year: 2004

description: The Kelvin-Helmholtz (KH) instability occurring in a single shear flow configuration that is embedded in a uniform flow-aligned magnetic field, is revisited by means of high resolution two-dimensional (2D) magnetohydrodynamic (MHD) simulations. First, the calculations extend previous studies of magnetized shear flows to a higher compressibility regime. The nonlinear evolution of an isolated KH billow emerging from the fastest growing linear mode for a convective sonic Mach number $M_{cs}=0.7$ layer is in many respects similar to its less compressible counterpart (Mach $M_{cs}=0.5$). In particular, the disruptive regime where locally amplified, initially weak magnetic fields, control the nonlinear saturation process is found for Alfvén Mach numbers $4\simlt M_A \simlt 30$. The most notable difference between $M_{cs}=0.7$ versus $M_{cs}=0.5$ layers is that higher density contrasts and fast magnetosonic shocklet structures are observed. Second, the use of adaptive mesh refinement allows to parametrically explore much larger computational domains, including up to 22 wavelengths of the linearly dominant mode. A strong process of large-scale coalescence is found, whatever the magnetic field regime. It proceeds through continuous pairing/merging events between adjacent vortices up to the point where the final large-scale vortical structure reaches the domain dimensions. This pairing/merging process is attributed to the growth of subharmonic modes and is mainly controlled by relative phase differences between them. These grid-adaptive simulations demonstrate that even in very weak magnetic field regimes ($M_A \simeq 30$), the large-scale KH coalescence process can trigger tearing-type reconnection events previously identified in cospatial current-vortex sheets.

description: In this paper, I analyze how the higher education decision of young adults in Germany depends on their expected future earnings. For this, I estimate a microeconometric model in which individuals maximize life-time utility by choosing whether or not to enter higher education. To forecast individual life cycles in terms of employment, earnings, and family formation under higher education and its alternative, vocational training, I use a dynamic microsimulation model and regression techniques. I take into account that while individuals generally choose between two options, higher education and vocational training, they are aware of multiple potential realizations under both options, such as leaving higher education with a bachelor degree or taking up higher education after first having earned a vocational degree. Using the estimates from the decision model, I simulate the introduction of different tuition fee and graduate tax scenarios. I find that the impact of these education policies on the higher education decision is limited and only few individuals would change their educational decisions as a reaction to these policies.

description: This report examines the agricultural trade policy environment surrounding the 1985 farm legislation. The report has several central themes. First, U.S. domestic farm programs project a trade policy to other nations; that is, the trade effects of U.S. policies are not neutral. Second, the trade effects of U.S. policies differ according to the export demand situation facing the United States. Third, macroeconomic policies could have a major impact on achieving the,objectives of U.S. farm policy established in the 1985 farm legislation.

description: This technical analysis updates the interrelationships of economic, institutional, and physical factors that affect supply, demand, and prices for U.S. rice in an earlier ERS report. Rice yields are affected by the climatic conditions in each area, technological changes, area in rice, and other factors. Lagged farm price did not appear to influence rice yields during 1950-83. Farm price deflated by cost of production, Government programs, and previous acreage affects area seeded to rice. Production response to a price change (elasticity) varies from 0.06 in Arkansas to 0.18 in California. Income and population are major variables affecting food rice and brewers rice consumption. Changes in retail price have a minor impact on demand. Total world exports are more elastic than U.S. exports, indicating U.S. commercial exports are moving into differentiated markets with a differentiated product.

description: The quasi-2D metal Sr$_2$RuO$_4$ is one of the best characterized unconventional superconductors, yet the nature of its superconducting order parameter is still highly debated. This information is crucial to determine the pairing mechanism of Cooper pairs. Here we use ultrasound velocity to probe the superconducting state of Sr$_2$RuO$_4$. This thermodynamic probe is symmetry-sensitive and can help to identify the superconducting order symmetry. Indeed, we observe a sharp jump in the shear elastic constant $c_{66}$ as the temperature is raised across the superconducting transition at $T_c$. This directly implies that the superconducting order parameter is of a two-component nature. Based on symmetry argument and given the other known properties of Sr$_2$RuO$_4$, we discuss what states are compatible with this requirement and propose that the two-component order parameter, namely $\lbrace d_{xz}; d_{yz} \rbrace$, is the most likely candidate.

description: EThis report identifies U.S. producers of labor-intensive crops most likely to be exposed to more competition if immigration reform increases their labor costs. Import market share data indicate that U.S. producers dominated the 1980-88 consumer market for most of the fruits and vegetables examined. However, five commodities--frozen broccoli, frozen cauliflower, fresh asparagus, fresh tomatoes, and fresh grapes--experience stiff competition from non-U.S. producers. Producers of these commodities are probably most vulnerable if competition intensifies, since foreign producers are already making inroads into these markets.
