description: Microstructures from deep ice cores reflect the dynamic conditions of the drill location as well as the thermodynamic history of the drill site and catchment area in great detail. Ice core parameters (crystal lattice-preferred orientation (LPO), grain size, grain shape), mesostructures (visual stratigraphy) as well as borehole deformation were measured in a deep ice core drilled at Kohnen Station, Dronning Maud Land (DML), Antarctica. These observations are used to characterize the local dynamic setting and its rheological as well as microstructural effects at the EDML ice core drilling site (European Project for Ice Coring in Antarctica in DML). The results suggest a division of the core into five distinct sections, interpreted as the effects of changing deformation boundary conditions from triaxial deformation with horizontal extension to bedrock-parallel shear. Region 1 (uppermost approx. 450 m depth) with still small macroscopic strain is dominated by compression of bubbles and strong strain and recrystallization localization. Region 2 (approx. 450–1700 m depth) shows a girdle-type LPO with the girdle plane being perpendicular to grain elongations, which indicates triaxial deformation with dominating horizontal extension. In this region (approx. 1000 m depth), the first subtle traces of shear deformation are observed in the shape-preferred orientation (SPO) by inclination of the grain elongation. Region 3 (approx. 1700–2030 m depth) represents a transitional regime between triaxial deformation and dominance of shear, which becomes apparent in the progression of the girdle to a single maximum LPO and increasing obliqueness of grain elongations. The fully developed single maximum LPO in region 4 (approx. 2030–2385 m depth) is an indicator of shear dominance. Region 5 (below approx. 2385 m depth) is marked by signs of strong shear, such as strong SPO values of grain elongation and strong kink folding of visual layers. The details of structural observations are compared with results from a numerical ice sheet model (PISM, isotropic) for comparison of strain rate trends predicted from the large-scale geometry of the ice sheet and borehole logging data. This comparison confirms the segmentation into these depth regions and in turn provides a wider view of the ice sheet.

description: ASAS J174406+2446.8 was originally found as a $δ$ Scuti-type pulsating star with the period P=0.189068 $days$ by ASAS survey. However, the LAMOST stellar parameters reveal that it is far beyond the red edge of pulsational instability strip on the $\log g-T$ diagram of $δ$ Scuti pulsating stars. To understand the physical properties of the variable star, we observed it by the 1.0-m Cassegrain reflecting telescope at Yunnan Observatories. Multi-color light curves in B, V, R$_{c}$ and I$_{c}$ bands were obtained and are analyzed by using the W-D program. It is found that this variable star is a shallow-contact binary with an EB-type light curve and an orbital period of 0.3781\,days rather than a $δ$ Scuti star. It is a W-subtype contact binary with a mass ratio of $1.135(\pm0.019)$ and a fill-out factor of $10.4(\pm5.6)\,\%$. The situation of ASAS J174406+2446.8 resembles those of other EB-type marginal-contact binaries such as UU Lyn, II Per and GW Tau. All of them are at a key evolutionary phase from a semi-detached configuration to a contact system predicted by the thermal relaxation oscillation theory. The linear ephemeris was corrected by using 303 new determined times of light minimum. It is detected that the O - C curve shows a sinusoidal variationthat could be explained by the light-travel-time effect via the presence of a cool red dwarf. The present investigation reveals that some of the $δ$ Scuti-type stars beyond the red edge of pulsating instability strip on the $\log g-T$ diagram are misclassified eclipsing binaries. To understand their structures and evolutionary states, more studies are required in the future.

description: Not so long ago, a method was discovered that successfully overcomes the catastrophic forgetting in neural networks. Although we know about the cases of using this method to preserve skills when adapting pre-trained networks to particular tasks, it has not obtained widespread distribution yet. In this paper, we would like to propose an alternative method of overcoming catastrophic forgetting based on the total absolute signal passing through each connection in the network. This method has a simple implementation and seems to us essentially close to the processes occurring in the brain of animals to preserve previously learned skills during subsequent learning. We hope that the ease of implementation of this method will serve its wide application.

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: This work is devoted to explore the effects of $f(G,T)$ terms on the study of structure scalars and their influences in the formulations of the Raychaudhuri, shear and Weyl scalar equations. For this purpose, we have assumed non-static spherically symmetric geometry coupled with shearing viscous locally anisotropic dissipative matter content. We have developed relations among the Misner-Sharp mass, Weyl scalar, matter and structure variables. We have also formulated set of $f(G,T)$ structure scalars after orthogonally breaking down of the Riemann curvature tensor. The influences of these scalar functions in the modeling of relativistic radiating spheres are also studied. The factor involved in the emergence of inhomogeneities is also explored for the constant and varying modified curvature corrections. We inferred that $f(G,T)$ structure scalars could lead provide an effective tool to study Penrose-Hawking singularity theorems and Newman-Penrose formalism.

description: We consider the problem of finding a subgraph of a given graph which maximizes a given function evaluated at its degree sequence. While the problem is intractable already for convex functions, we show that it can be solved in polynomial time for convex multi-criteria objectives. We next consider the problem with separable objectives, which is NP-hard already when all vertex functions are the square. We consider a colored extension of the separable problem, which includes the notorious exact matching problem as a special case, and show that it can be solved in polynomial time on graphs of bounded tree-depth for any vertex functions. We mention some of the many remaining open problems.

description: The local Langlands correspondence for GL(n) of a non-Archimedean local field $F$ parametrizes irreducible admissible representations of $GL(n,F)$ in terms of representations of the Weil-Deligne group $WD_F$ of $F$. The correspondence, whose existence for $p$-adic fields was proved in joint work of the author with R. Taylor, and then more simply by G. Henniart, is characterized by its preservation of salient properties of the two classes of representations. The article reviews the strategies of the two proofs. Both the author's proof with Taylor and Henniart's proof are global and rely ultimately on an understanding of the $\ell$-adic cohomology of a family of Shimura varieties closely related to GL(n). The author's proof with Taylor provides models of the correspondence in the cohomology of deformation spaces, introduced by Drinfeld, of certain $p$-divisible groups with level structure.

Trade Reforms, Mark-Ups and Bargaining Power of Workers: the Case of Ethiopian Manufacturing Firms

Subjects: subject: International Relations/Trade

description: There is a predominant preposition in trade theory that firms operating in an imperfect market with trade barriers often set prices with a positive mark-up. Workers using insider information tend to bargain and share the rent from firms’ market power; which is negatively associated with to decline with trade reforms. Empirical evidences are, nonetheless, mixed. Trade reforms that took place between 1991 and 2002 in Ethiopia inspired the study to investigate the proposition. Using firm level unbalanced data of manufacturing firms employing more than 100 permanent workers between 1996 and 2007, a model of mark-up with labor bargaining power was estimated using random effects and LDPDM. The estimates of the two models are similar. Albeit huge inter-firm variations, the average estimated mark-ups has not only been positive but also increased even after the reform. This may be perhaps because of the 17.5 percent weighted average tariff rate that has still been maintained after the reform. Workers’ bargaining power parameter estimate remained negative over the study period; possibly because of high unemployment and low reservation wage. The rate of rent extraction from workers declined on average in the post reform period. Thus, further opening up of markets may bring a competitive push to improve firm performance, reduce market power of firms and the rent extraction from workers. There is a need to attract additional investment (both public and private) in the economy and addressing causes of capacity underutilization of incumbent firms may lessen unemployment problems and thereby improve workers bargaining power and their earnings.

description: Understanding change is critical to policy formulation. Who benefits, who loses from change, and what causes change are core policy questions. Panel data are central to understanding change, and this special issue of the journal is devoted to five papers examining change in wellbeing as measured by two waves of data from the Ethiopia Socioeconomic Survey (ESS). The papers cover changes in consumption poverty, multi-dimensional poverty, food security, malnutrition in the form of wasting and underweight status, and smoothing patterns of nonfarm enterprise activities. The ESS data is freely available for download and immediate use. While the papers in this issue draw from the first two waves of data (2011-12 and 2013-14), the third wave of the ESS (2015-16) is now also publicly available. The ESS is a collaborative effort of the Central Statistical Agency of Ethiopia and the World Bank’s Living Standards Measurement Study – Integrated Surveys of Agriculture program.

description: Metal halide perovskites (MHPs) are nowadays one of the most studied semiconductors due to their exceptional performance as active layers in solar cells. Although MHPs are excellent solid-state semiconductors, they are also ionic compounds, where ion migration plays a decisive role in their formation, their photovoltaic performance and their long-term stability. Given the above-mentioned complexity, molecular dynamics simulations based on classical force fields are especially suited to study MHP properties, such as lattice dynamics and ion migration. In particular, the possibility to model mixed compositions is important since they are the most relevant to optimize the optical band gap and the stability. With this intention, we employ DFT calculations and a genetic algorithm to develop a fully transferable classical force field valid for the benchmark inorganic perovskite compositional set CsPb(Br_xI_(1-x))_3 (x = 0,1/3,2/3,1). The resulting force field reproduces correctly, with a common set of parameters valid for all compositions, the experimental lattice parameter as a function of bromide/iodide ratio, the ion-ion distances and the XRD spectra of the pure and mixed structures. The simulated thermal conductivities and ion migration activation energies of the pure compounds are also in good agreement with experimental trends. Our molecular dynamics simulations make it possible to predict the compositional dependence of the ionic diffusion coefficient on bromide/iodide ratio and vacancy concentration. For vacancy concentrations of around 9 10^21 cm^-3, we obtained ionic diffusion coefficients at ambient temperature of 10^-11 and 10^-13 cm2/s for CsPbBr3 and CsPbI3, respectively. Interestingly, in comparison with the pure compounds, we predict a significantly lower activation energy for vacancy migration and faster diffusion for the mixed perovskites.

description: Poverty can take many different forms, ranging widely over dimensions both monetary, such as consumption or income, and nonmonetary, such as health and education. One large class of nonmonetary measures of poverty is the multidimensional poverty index (MPI); recent studies document that people identified as poor in one dimension are often different from those who found to be poor in another dimension. This paper extends the literature by examining whether MDP dynamics are similar to the dynamics of a related consumption based measure of poverty. Using two waves of Ethiopian panel data (2011-12 and 2013-14) we estimate poverty based on a monetary value of real consumption and a non monetary weighted deprivation index (our underlying measure of MDP). Similar to studies for other countries, we find that the two estimates of poverty identify significantly different groups of Ethiopians as poor. A key contribution of this paper is the finding that changes in consumption are largely independent of changes in multidimensional wellbeing: Awareness that an individual’s wellbeing improved over time as measured by improvements in the weighted deprivation index provides no information about whether his or her well being has improved where consumption is concerned.

description: How much time does it take for a fluctuating system, such as a polymer chain, to reach a target configuration that is rarely visited -- typically because of a high energy cost ? This question generally amounts to the determination of the first-passage time statistics to a target zone in phase space with lower occupation probability. Here, we present an analytical method to determine the mean first-passage time of a generic non-Markovian random walker to a rarely visited threshold, which goes beyond existing weak-noise theories. We apply our method to polymer systems, to determine (i) the first time for a flexible polymer to reach a large extension, and (ii) the first closure time of a stiff inextensible wormlike chain. Our results are in excellent agreement with numerical simulations and provide explicit asymptotic laws for the mean first-passage times to rarely visited configurations.

description: This paper examines the dynamics of wellbeing in Ethiopia by assessing changes in poverty status based on consumption and asset ownership. Using panel data from the first two waves of the Ethiopia Socioeconomic Survey (ESS), we discover that although the cross-sectional poverty remains relatively unchanged (approximately 30% in both 2012 and 2014), the proportion of the population experiencing consumption poverty at some point during this period is 47%. An asset-based measure of poverty exhibits fewer transitions in and out of poverty. Examination of the direction and magnitude of change in consumption both at aggregate and subgroup levels indicates that despite a stagnant poverty rate, consumption patterns have changed significantly. The forward movers and non-poor households have increased their share of spending on nutrient-dense foods, while the chronic poor and backward movers have increased spending shares on staples (reduced on nutrient-dense foods). Our findings indicate that availability of longitudinal data at the household level provides additional insights on the dynamics of wellbeing that would be impossible to understand using cross sectional data only.

description: Using panel data from the Ethiopia Socioeconomic Survey (ESS), representative of all people living in rural and small-town areas, this paper describes changing patterns of food security between 2012 and 2014. We examine four measures of food security – two consumption based (calories and dietary diversity) and two experience based (whether food insecurity was experienced in any month, and whether any actions were taken in response).Over all four measures in both years, the share of the food insecure population was never less than 25 percent. Disentangling chronic from transitory food insecurity is important for policy design and for estimating the total food insecurity count over time. For example, the average rate of inadequate dietary diversity was approximately 30 percent in both 2012 and 2014, but the panel data reveal that 46 percent of the rural and small-town population had inadequately diverse diets at some point over the period. While the cross-sectional estimates suggest similar patterns in levels and trends of the measures, the panel data reveal that there is very little comovement of the measures. For example, observing that someone has improved in terms of dietary diversity does not reveal information as to whether she or he has similarly improved in terms of the experiential-based measures.

In the Sudanian Savanna of Mali, as elsewhere in the West African Sahel, dryland cereals are grown on fields managed collectively and individually by extended families that span multiple generations and multiple households, headed by an elder patriarch who is responsible for organizing land and labor to meet staple food needs. We refer to these, as does the government of Mali, by the term Enterprise Agricole Familiale.
Isotropisation of flat homogeneous Bianchi type I model with a non minimally coupled and massive scalar field

description: In previous works, we studied the isotropisation of Bianchi class A models with a minimally coupled scalar field. In this paper, we extend these results to the case of a non minimally coupled one. We first make the calculations in the Einstein frame where the scalar field is minimally coupled to the curvature but non minimally coupled to the perfect fluid. Then, we use a conformal transformation to generalise our results to a scalar field non minimally coupled to the curvature. Universe isotropisation for the Brans-Dicke and low energy string theories are studied.

description: In Ethiopia, 9.7 percent of rural and 28.7 percent of small-town children are wasted and underweight, and under nutrition is responsible for a large percentage of childhood deaths. We use two waves of panel data, from the 2012 and 2014 Ethiopia Socioeconomic Surveys, to assess the dynamics of weight-for-height z-score, wasting, weight-for-age z-score, and underweight among children aged 6-59 months. Ordinary least squares (OLS) and fixed effects regression models are used to examine the associations of individual, household, and community factors with each outcome. The cross-sectional results, which generally parallel previous findings, suggest that child’s sex, recent illnesses, household assets, and livestock ownership are correlated with nutritional status. However, many associations disappear after controlling for fixed effects; only recent illness and community access to a main road are consistently significant determinants of changes in nutrition status. Thus, changing factors traditionally identified as correlates of undernutrition may not be enough to improve children’s nutrition. Further panel analysis, conditional on baseline nutrition status, shows that drivers of change are asymmetrical—a finding important for policy development.

Stability of vacuum for the Boltzmann Equation with moderately soft potentials
Creators: name: Chaturvedi, Sanchit
Publisher: name: arXiv
Year: 2020
Subjects: subject: Analysis of PDEs (math.AP)
subject: FOS: Mathematics

description: We consider the spatially inhomogeneous non-cutoff Boltzmann equation with moderately soft potentials and any singularity parameter $s\in (0,1)$, i.e. with $γ+2s\in(0,2]$ on the whole space $\mathbb{R}^3$. We prove that if the initial data $f_{\text{in}}$ are close to the vacuum solution $f_{\text{vac}}=0$ in an appropriate weighted norm then the solution $f$ remains regular globally in time and approaches a solution to a linear transport equation. Our proof uses $L^2$ estimates and we prove a multitude of new estimates involving the Boltzmann kernel without angular cut-off. Moreover, we rely on various previous works including those of Gressman--Strain, Henderson--Snelson--Tarfulea and Silverstre. From the point of view of the long time behavior we treat the Boltzmann collisional operator perturbatively. Thus an important challenge of this problem is to exploit the dispersive properties of the transport operator to prove integrable time decay of the collisional operator. This requires the most care and to successfully overcome this difficulty we draw inspiration from Luk's work [Stability of vacuum for the Landau equation with moderately soft potentials, Annals of PDE (2019) 5:11] and that of Smulevici [Small data solutions of the Vlasov-Poisson system and the vector field method, Ann. PDE, 2(2):Art. 11, 55, 2016]. In particular, to get at least integrable time decay we need to consolidate the decay coming from the space-time weights and the decay coming from commuting vector fields.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Agricultural cooperatives operate under the notion that smallholder farmers are better off working collectively. Rwanda’s coffee sector has experienced a significant transformation over the past two decades, which includes farmers coming together to establish cooperative coffee washing stations (CWSs). Our data and analysis show that these collectives provide farmers with a myriad of services that include economic, agronomic and social benefits. We find that cooperative membership affects adoption of specific practices, most notably pesticide application. This finding, however cannot be generalized to all best management practices as we find that membership is not associated with uptake of some practices (like fertilizer use) and in some instances it can contribute to a lower likelihood of adoption. Among other differences, we find that cooperative members attain higher levels of productivity, however our analysis cannot confirm this to be a causal relationship. We note that collective action in Rwanda’s coffee sector needs additional research attention, as these types of farmer associations don’t always thrive or provide the same level of services that their members expect. We derive implications of our findings and identify areas in need of further inquiry.

description: Considering well localized atom, the mean field theory (MFT) was applied to replace the operators by equivalent expectation values. The Rabi model was reduced to a fourth orders NDE describing atoms position. Solution by the harmonic balance method (HBM) showed good accuracy and consistency to the numerical results, which introduces it as a useful tool in the quantum dynamics studies.
A Two-Stream Symmetric Network with Bidirectional Ensemble for Aerial Image Matching

description: In this paper, we propose a novel method to precisely match two aerial images that were obtained in different environments via a two-stream deep network. By internally augmenting the target image, the network considers the two-stream with the three input images and reflects the additional augmented pair in the training. As a result, the training process of the deep network is regularized and the network becomes robust for the variance of aerial images. Furthermore, we introduce an ensemble method that is based on the bidirectional network, which is motivated by the isomorphic nature of the geometric transformation. We obtain two global transformation parameters without any additional network or parameters, which alleviate asymmetric matching results and enable significant improvement in performance by fusing two outcomes. For the experiment, we adopt aerial images from Google Earth and the International Society for Photogrammetry and Remote Sensing (ISPRS). To quantitatively assess our result, we apply the probability of correct keypoints (PCK) metric, which measures the degree of matching. The qualitative and quantitative results show the sizable gap of performance compared to the conventional methods for matching the aerial images. All code and our trained model, as well as the dataset are available online.

description: In developing countries highly dependent on agriculture, non-farm enterprises (NFEs) are often lauded as income diversification opportunities, helping to smooth income in the farming off-seasons. Using data from the first wave of the Ethiopia Socioeconomic Survey (ESS), a nationally representative survey of rural and small town Ethiopia, we explore the role NFEs play in seasonal income generation, consumption smoothing, and risk mitigation. We find that NFEs are in fact pro-cyclical with agriculture, with the most productive months of NFE operation coinciding with the harvest season and crop sales. This procyclicality appears to be driven by demand-side factors, where increases in community income through crop sales generate higher demand for NFE goods and services. We also find no evidence that households operating NFEs are better able to ward off incidence or duration of food insecurity in the face of shocks, suggesting NFEs do not insure temporally vulnerable households against risks.
