description: We generalize the notions of dual pair and polarity introduced by S. Lie and A. Weinstein in order to accommodate very relevant situations where the application of these ideas is desirable. The new notion of polarity is designed to deal with the loss of smoothness caused by the presence of singularities that are encountered in many problems. We study in detail the relation between the newly introduced dual pairs, the quantum notion of Howe pair, and the symplectic leaf correspondence of Poisson manifolds in duality. The dual pairs arising in the context of symmetric Poisson manifolds are treated with special attention. We show that in this case and under very reasonable hypotheses we obtain a particularly well behaved kind of dual pairs that we call von Neumann pairs. Some of the ideas that we present in this paper shed some light on the so called optimal momentum maps.

description: Нефть и газ как полезные ископаемые являются компонентом минерально-сырьевого ресурса национальной экономики, и их наличие обеспечивает минерально-сырьевую безопасность страны, которая в свою очередь, являясь составной частью экономической безопасности. Однако сам по себе запас нефти и газа в недрах территории еще не означает участие этих полезных ископаемых в процессе обеспечения экономической безопасности. До того момента, как источники, месторождения этих полезных ископаемых не будут открыты и разработаны промышленным способом, пока нефть и газ не будут извлекаться на поверхность, не будут транспортироваться и специальным способом в соответствии с современными технологическими требованиями подготовлены к извлечению из них необходимых веществ в виде топлива или нефтехимического сырья - до этого момента сам факт присутствия нефти и газа в недрах земли не имеет никакого значения для экономической безопасности страны. Только будучи извлеченными, нефть и газ становятся факторами минерально-сырьевой безопасности. А это требует планомерной политики в сфере обрабатывающей промышленности.
Constructing a complete integral of the Hamilton-Jacobi equation on pseudo-Riemannian spaces with simply transitive groups of motions

description: In this work, an efficient method for constructing a complete integral of the geodesic Hamilton-Jacobi equation on pseudo-Riemannian manifolds with simply transitive groups of motions is suggested. The method is based on using a special transition to canonical coordinates on coadjoint orbits of the group of motion. As a non-trivial example, we consider the problem of constructing a complete integral of the geodesic Hamilton-Jacobi equation in the McLenaghan-Tariq-Tupper spacetime. An essential feature of this example is that the Hamilton-Jacobi equation is not separable in the corresponding configuration space.

description: In this paper, investigation has been made to analyse the marketable and marketed surpluses of leading crops viz. different varieties of rice, wheat, potato, mustard and lentil. This study suggests that marketed surplus as percentage of total production was found highest in potato (64 per cent) followed by lentil (59.5 per cent), Boro paddy (57.5 per cent), mustard (52.7 per cent), Aman paddy (48 per cent), Aus paddy (38 per cent) and wheat (14 per cent). Small farmers were the large suppliers of agricultural crops during harvest time and sell out crops to meet up their cash obligation when the prices remain low. On the other hand, they purchase the same crop at off-season to meet up their consumption requirement and at that time prices remain high. So, small farmers were worse off by this seasonal sales pattern and price variation. Large farmers received the highest prices prevailed in the market relatively with strong bargaining capacity with the market intermediaries and their pre-harvest time sales is higher than other size group of farms. This study suggested that among different explanatory variables, farmers were very much price sensitive irrespective of their farm sizes. Price elasticity of marketable surplus as estimated for Aman paddy, Boro paddy, wheat, potato and mustard appeared 1.89, 2.7, 1.23, 2.46 and 1.40, i.e. prices significantly influenced marketable surpluses of these crops. In general, marketable surpluses of crops reflect farmers well-being. So, price policy influencing output prices have important role in increasing marketable and marketed quantities. This study suggested some policy options based on research findings which should help the policy markers to adopt appropriate measures to increase marketed surplus in Bangladesh agriculture leading to a gradually commercialised agriculture.

description: It remains controversial as to whether a face-centered cubic (FCC) phase exists in pure titanium (Ti) upon deformation, since the FCC structures in deformed Ti may well be TiHx resulting from the sample preparation process. Here, by using in situ transmission electron microscopy (TEM), we uncover direct evidences on the nucleation and growth of FCC-Ti right in front of the crack tip in the α-Ti matrix. Atomic resolution images further reveal that the transformation can be mediated by either partial dislocations on basal planes or shear and atomic shuffle on the FCC1 1 0|HCP1 0 -1 0 interfaces. FCC-Ti's formation in pure α-Ti through deformation is controversial. In situ TEM observed FCC-Ti nucleation and growth in α-Ti matrix near the crack tip and revealed the mechanism.

description: Public and private institutions must often allocate scare resources under uncertainty. Banks, for example, extend credit to loan applicants based in part on their estimated likelihood of repaying a loan. But when the quality of information differs across candidates (e.g., if some applicants lack traditional credit histories), common lending strategies can lead to disparities across groups. Here we consider a setting in which decision makers -- before allocating resources -- can choose to spend some of their limited budget further screening select individuals. We present a computationally efficient algorithm for deciding whom to screen that maximizes a standard measure of social welfare. Intuitively, decision makers should screen candidates on the margin, for whom the additional information could plausibly alter the allocation. We formalize this idea by showing the problem can be reduced to solving a series of linear programs. Both on synthetic and real-world datasets, this strategy improves utility, illustrating the value of targeted information acquisition in such decisions. Further, when there is social value for distributing resources to groups for whom we have a priori poor information -- like those without credit scores -- our approach can substantially improve the allocation of limited assets.

description: We find a new Penrose limit of AdS_5*S^5 that gives the maximally symmetric pp-wave background of type IIB string theory in a coordinate system that has a manifest space-like isometry. This induces a new pp-wave/gauge-theory duality which on the gauge theory side involves a novel scaling limit of N=4 SYM theory. The new Penrose limit, when applied to AdS_5*S^5/Z_M, yields a pp-wave with a space-like circle. The dual gauge theory description involves a triple scaling limit of an N=2 quiver gauge theory. We present in detail the map between gauge theory operators and string theory states including winding states, and verify agreement between the energy eigenvalues obtained from string theory and those computed in gauge theory, at least to one-loop order in the planar limit. We furthermore consider other related new Penrose limits and explain how these limits can be understood as part of a more general framework.

description: Based on national level data from secondary sources, the magnitude of changes in average production and the sources of changes for the Bangladesh as a whole were measured for major food grains - rice (Aus, Aman and Boro) and wheat during 1979/80 to 1998/99 which was again sub-divided between two time periods, before full-implementation of privatization policies (1979/80-1988/89) and after full-implementation of privatization policies (1989/90-1998/99). The findings showed that average area of Boro rice and wheat increased during the whole period of study. However, during the period after full-implementation of privatization policies the areas under Aus, wheat as well as total food grains decreased. Further, it was found that except Aus, average production of all types of food grains increased and except wheat, average yield of all types of food grains also increased during the same period. The analysis showed that in the cases of Aus and Boro rice as well as total food grains, change in mean area; and in the cases of Aman rice and wheat changes in mean yield were the main sources of change in mean production in Bangladesh. It was also found that Boro rice appeared to be the highest and Aus rice appeared to be the lowest contributors in increasing mean production of total food grains. Finally, some policy conclusions are drawn with respect to improvement of production levels of major food grains.

Lithium as a passive tracer probing the rotating solar tachocline turbulence

Subjects: subject: Astrophysics (astro-ph)

description: The rotational influence on the eddy-diffusivity tensor D_ij for anisotropic turbulence fields is considered in order to explain the lithium decay law during the spin-down process of solar-type stars. Rotation proves to be highly effective in the transfer of chemicals through the solar tachocline (beneath the convection zone) which is assumed to contain only turbulence with horizontal motions. The effect is so strong that the tachocline turbulence must not exceed a limit of ~10^-(3...4) of the rms velocity in the convection zone in order to let the lithium survive after Gigayears. Such long depletion times can also be explained by a very small rotational influence upon the eddy-diffusion tensor if it is realized with correlation times shorter than 15 min. It is argued that such slow and/or short-living turbulence beneath the convection zone could hardly drive the solar dynamo. In our theory the diffusion remains small for rapid rotation due to the rotational quenching of the turbulence. In young stellar clusters like Pleiades, there should be a (positive) correlation between rotation rate and lithium abundance, where the fastest stars should have maximal lithium. First inspections of the data seem to confirm this finding.

description:
According to the Great Replacement conspiracy theory, nonwhites, globalists and elites are plotting to eliminate the white race and its dominance through anti-white policies and increased immigration. In that context, abortion among white women is perceived by white nationalists (WN) as a betrayal of their ‘biological’ and ‘traditional’ gender role – procreation of white babies. While WN condemn abortion among white women as a murderous sin, at times they encourage the practice among nonwhites to solve demographic threats to white dominance. In this study, we use mixed methods, combining unsupervised machine learning with close textual analysis of 30,725 posts including the term ‘abortion’ published on the WN website Stormfront between 2001 and 2017. We identify three broad themes: White genocide, focused on the conspiracy theory and detailing the active actors in its alleged execution; political, focused on political agendas and laws; and WN reproductive reasoning, articulating and justifying the contradiction between supporting abortion for nonwhites but not for whites via politics of difference that emphasize nonwhites’ supposed inferior morality. We discuss WN’s unique and explicitly racist discourse around a medical topic like abortion, a staple of the conservative and religious right for decades, and how it is used to alleviate their cognitive dissonance resulting from their dual-stance on abortion. Such discourse could be harnessed to recruit members into the movement and normalize extreme, racist ideologies.

description: Psychological bias towards, or away from, a prior measurement or a theory prediction is an intrinsic threat to any data analysis. While various methods can be used to avoid the bias, e.g. actively not looking at the result, only data blinding is a traceable and thus trustworthy method to circumvent the bias and to convince a public audience that there is not even an accidental psychological bias. Data blinding is nowadays a standard practice in particle physics, but it is particularly difficult for experiments searching for the neutron electric dipole moment, as several cross measurements, in particular of the magnetic field, create a self-consistent network into which it is hard to inject a fake signal. We present an algorithm that modifies the data without influencing the experiment. Results of an automated analysis of the data are used to change the recorded spin state of a few neutrons of each measurement cycle. The flexible algorithm is applied twice to the data, to provide different data to various analysis teams. This gives us the option to sequentially apply various blinding offsets for separate analysis steps with independent teams. The subtle modification of the data allows us to modify the algorithm and to produce a re-blinded data set without revealing the blinding secret. The method was designed for the 2015/2016 measurement campaign of the nEDM experiment at the Paul Scherrer Institute. However, it can be re-used with minor modification for the follow-up experiment n2EDM, and may be suitable for comparable efforts.

description: The dicentric chromosome assay (DCA), the gold standard for radiation biodosimetry, evaluates an individual absorbed radiation dose by the analysis of DNA damage in human lymphocytes. The conventional (C-DCA) and QuickScan (QS-DCA) scoring methods are sensitive for estimating radiation dose. The Biodosimetry Laboratory at Institute of Nuclear Energy Research (INER), Taiwan, participated in intercomparison exercises conducted by Health Canada (HC) in 2014, 2015 and 2018 to validate the laboratory’s accuracy and performance. Blood samples for the conventional dose response curve for Taiwan were irradiated with 0, 0.25, 0.5, 1, 2, 3, 4 and 5 Gy. Ten blind blood samples were provided by HC. Either or both of two methods of conventional (C) or QuickScan (QS) scoring could be chosen for the HC’s intercomparison. For C-DCA triage scoring, only cells with 46 centromeres were counted and each scorer recorded the number of dicentrics in the first 50 metaphases or stopped scoring when 30 dicentrics were reached. Scorers also recorded how much time it took to analyze 10, 20, and 50 cells. Subsequently, the data were entered into the Dose Estimate software (DoseEstimate_v5.1) and dose estimates were calculated. With QS-DCA scoring, a minimum of 50 metaphase cells (or 30 dicentrics) were scored in apparently complete metaphases without verification of exactly 46 centromeres. For the blinded blood samples irradiated at HC and shipped to INER, the mean absolute deviation (MAD) derived after scoring 50 cells for C-DCA and QS-DCA was <0.5 Gy for all three intercomparisons, meeting the criteria for acceptance. The results indicated that the Biodosimetry Laboratory at INER can provide reliable dose estimates in the case of a large-scale radiation accident.

description:
Dynamical systems can show so-called quasi-periodic solutions, which are composed of two or more so-called incommensurable frequencies. Solving these systems in the time-domain is not favorable, due to the fact that quasi-periodic solutions have no finite periodicity, thus it is unclear how long simulations must be carried out in order to capture all relevant information. The time-solution however fills a toroidal manifold densely. To calculate the invariant manifold directly one can use the hyper-time parametrization. One can easily extract maximum values from the hyper-time solution. The trade-off however is, that the parametrization loses its validity if the quasi-periodic solution synchronizes. When continuing quasi-periodic solution branches it is essential to detect an approach to such synchronization points. We present an algorithm, with which one can detect synchronization by suppression of quasi-periodic solutions, on the basis of a solution in the hyper-time parametrization.

description: The study was undertaken during 2001-02 to evaluate the past investment on research and extension of maize in Bangladesh. For the purpose, Economic Surplus Model with ex-post analysis was used to estimate the returns to investment on composite varieties and hybrids of maize that have replaced the local varieties. The growth rate of area, production and yield of maize were increased dramatically after the release of maize varieties. The internal rate of return (IRR) to investment was calculated at 23%. During 2000-01, about 65.70% more maize production was made available because of the farmers' adoption of composite varieties and hybrids of maize. The yield of composite varieties of maize ranged from 40 to 65% and hybrids ranged from 73 to 79% higher over the local varieties. Under various assumptions about the research and extension expenditures, the IRR ranged from 17 to 28% and benefit cost ratio from 9 to 19. The accumulated foreign exchange saving since 1992-93 was Tk 291.59 billion. The study indicates that the funding of maize research and extension is a good investment. Therefore, both government and donor agencies should come forward to invest in maize research and strengthen extension activities in the country.

description: Phase transition at the initial solidification stage notably affects subsequent phase structure of peritectic alloys, however, detailed dynamics between entangled three-phase region remains ambiguous in the far-from-equilibrium condition during laser additive manufacturing. Here, in-situ peritectic phase transition during single-layer laser printing of an exemplary 304L stainless steel is directly investigated and quantified at high temporospatial resolution by high-speed synchrotron X-ray diffraction and imaging. These quantitative observations clarify the mechanism of coupled peritectic growth and local remelting at three-phase region. The results revealed provide in-depth understanding of phase transformation dynamics and delicate design of phase structure for metal additive manufacturing.

Observational results indicate that elliptical galaxies with older stellar populations (t > 7.5 Gyr) have rounder central isophotes than ellipticals with younger stellar populations. In addition, older ellipticals tend to have core profiles, while younger ellipticals tend to have power-law profiles. Numerical simulations of galaxy mergers indicate that if one or both of the progenitors have a central black hole with a mass around 0.2 percent of the mass in stars, then the effect of the black hole(s) is to make the central regions of the remnant rounder, with a characteristic time of a few gigayears.

description: Dislocation evolution in multilayered Ti/Nb composites processed by accumulative roll bonding under uniaxial tension was quantitatively evaluated by high-energy X-ray diffraction. The composites with different heterogeneous microstructures show distinct dislocation activities in Ti, which majorly contributes to their different ductility. For the composite in which extensive shear bands have formed before loading, the stable fraction of 〈c+a〉 dislocations and the suppressed activation of 〈c〉 dislocations contribute to its uniform deformation. We emphasize that tracking the dynamic evolution of dislocations is fundamental for understanding ductility of the multilayers, whereas the increased 〈c+a〉 dislocations found by post-mortem analysis do not necessarily dominate. Dynamic evolution of dislocations, rather than only dislocation densities obtained by post-mortem analysis, is found to explain ductility of multilayered composites, which can be tailored by adjusting heterogeneous microstructures.

description: We estimate the impact of drought tolerant maize varieties in 13 countries in sub-Saharan Africa using geo referenced farm-trial data from 49 locations in eastern and southern Africa. Planting dates were matched with rainfall data in order to generate better drought risk zones in each country. Maize drought tolerant varieties perform better than popular commercial maize varieties grown in sub-Saharan Africa. Estimates are in the range of $132-$353 million to producers and consumer accruing in the 13 countries during the 2017-2016 period. Analysis of risk based on higher moments of yield distribution points out that there are drought tolerant varieties that have the same level of risk but offer higher overall gains compared to popular commercial varieties.

description: We investigate the nucleon and pion gluon distribution functions in the framework of holographic QCD, focusing on the small Bjorken x region. Based on an approximate relation, the gluon distributions are extracted from structure functions of the unpolarized deep inelastic scattering which can be calculated with a holographic QCD model, assuming the Pomeron exchange. All the adjustable parameters of the model are determined with the HERA data of the proton structure functions. We explicitly show that the extracted proton gluon distribution is consistent with results of the recent global QCD analysis. The structure functions of the pion can be computed without any additional parameter, which enables us to predict its gluon distribution also. We find that the resulting pion gluon density is smaller than the proton's, and agrees with the recent global QCD analysis result within the uncertainties.

description: Using a moment based approach, introduced by Antle for producers’ risk behavior elicitation, we develop an empirical model to evaluate the implication of risk preferences on farm level diversification. For the purpose, we use a household level panel data of years 2004 and 2009 from Ethiopia. The estimation is done in two stages; the first one for the elicitation of risk aversion behavior of farm households and the second one, for the inclusion of the first estimate on the factors that determine the level of on-farm diversification. To control for endogeneity problem in the estimation of diversification equation, we use efficient two stage least squares technique. We find that farmers with higher level of relative risk premium will more likely opt for more on-farm diversification. The engagement of farm households to off and non-farm income generating activities could likely reduce the on-farm diversification level. These could be due to the fact that households with income from off and non-farm activities use this income as a safety net and go for specialized farms.

description: Советское трудовое право, существовавшее к моменту начала перестройки в СССР, распространялось на рабочих и служащих, обеспечивая им надежные юридические гарантии. Однако данная сфера трудового права предопределялась общественной собственностью на средства производства и отсутствием рынка свободной рабочей силы. Ситуация коренным образом изменилась после появления в СССР во второй половине 1980-х гг. многообразия форм собственности. Несмотря на доктринальные прогнозы о расширении предмета трудового права, распространение его на коммерческие организации, в реальности происходил обратный процесс - сужение предмета данной отрасли права.
Thermodynamics of a Kerr Newman de Sitter Black Hole

description: We compute the conserved quantities of the four-dimensional Kerr-Newman-dS (KNdS) black hole through the use of the counterterm renormalization method, and obtain a generalized Smarr formula for the mass as a function of the entropy, the angular momentum and the electric charge. The first law of thermodynamics associated to the cosmological horizon of KNdS is also investigated. Using the minimal number of intrinsic boundary counterterms, we consider the quasilocal thermodynamics of asymptotic de Sitter Reissner-Nordstrom black hole, and find that the temperature is equal to the product of the surface gravity (divided by $2π$) and the Tolman redshift factor. We also perform a quasilocal stability analysis by computing the determinant of Hessian matrix of the energy with respect to its thermodynamic variables in both the canonical and the grand-canonical ensembles and obtain a complete set of phase diagrams. We then turn to the quasilocal thermodynamics of four-dimensional Kerr-Newman-de Sitter black hole for virtually all possible values of the mass, the rotation and the charge parameters that leave the quasilocal boundary inside the cosmological event horizon, and perform a quasilocal stability analysis of KNdS black hole.

description: The Burrows-Wheeler-Transform (BWT) is a reversible string transformation which plays a central role in text compression and is fundamental in many modern bioinformatics applications. The BWT is a permutation of the characters, which is in general better compressible and allows to answer several different query types more efficiently than the original string. It is easy to see that not every string is a BWT image, and exact characterizations of BWT images are known. We investigate a related combinatorial question. In many applications, a sentinel character dollar is added to mark the end of the string, and thus the BWT of a string ending with dollar contains exactly one dollar-character. Given a string w, we ask in which positions, if any, the dollar-character can be inserted to turn w into the BWT image of a word ending with dollar. We show that this depends only on the standard permutation of w and present a O(n log n)-time algorithm for identifying all such positions, improving on the naive quadratic time algorithm. We also give a combinatorial characterization of such positions and develop bounds on their number and value. This is an extended version of [Giuliani et al. ICTCS 2019].

We compare correlations between global parameters, such as far-infrared luminosity, blue luminosity, and total molecular gas content, with other samples of galaxies, including normal galaxies, clusters and ultraluminous infrared galaxies. We find that overall our sample is a well defined subset of these other samples of galaxies.

description: This note introduces a class of nonlinear Neumann problems on balls expanding with the radii tending towards infinity. Performing singular perturbation arguments, we establish the corresponding concentration phenomenon and refined asymptotic expansions with the precise first two order terms. In doing so, we obtain the nontrivial boundary structure of solutions with effects coming from the nonlinear Neumann boundary condition and the boundary mean curvature varied with expanding domains.
