description: Factors determining the group performance of women-led self-help groups (SHGs) engaged in agroprocessing organized under Swarnajayanti Gram Swarozgar Yojna (SGSY) in Kerala have been studied following the multi-stage purposive and random sampling technique in the Thrissur district. It has been observed that socio-economic variables like age, education, market perception, economic motivation, attitude towards self-employment, management-orientation, risk-orientation, innovativeness and information-seeking behaviour influence the group performance of SHGs. The BPL women in SGSY-SHGs of the performing groups are around 30 years of age, with middle school level education. Education and age of respondents have negative correlation on group leadership. The group stability has been determined by factors like group cohesion, group leadership, team spirit, group decision-making and regularity in maintenance of records. Correlation analysis between group performance and socio-economic characters has revealed that management-orientation has a positive and significant influence on all the determinants of group performance, followed by information-seeking behaviour, knowledge about processing, market perception and economic motivation. The parameters like age of respondent, education of spouse, attitude towards self-employment and innovativeness have been found least influential on group performance. The study has indicated the need of providing training on management and technical aspects as well as provision of market infrastructure to the SHGs so that they could become competitive in the market.

description: Holography relates the quasinormal modes frequencies of AdS black holes to the pole structure of the dual field theory propagator. These modes thus provide the timescale for the approach to thermal equilibrium in the CFT. Here, we study how such pole structure and, in particular, the time to equilibrium can get modified in the presence of a black hole hair. More precisely, we consider in AdS a set of relaxed boundary conditions that allow for a low decaying graviton mode near the boundary, which triggers an additional degree of freedom. We solve the scalar field response on such background analytically and non-perturbatively in the hair parameter, and we obtain how the pole structure gets affected by the presence of a black hole hair, relative to that of the usual AdS black hole geometry. The setup we consider is a massive 3D gravity theory, which admits a one-parameter family deformation of BTZ solution and enables us to solve the problem analytically. The theory also admits an AdS$_3$ soliton which gives a family of vacua that can be constructed from the hairy black hole by means of a double Wick rotation. The spectrum of normal modes on the latter geometry can also be solved analytically; we study its properties in relation to those of the AdS$_3$ vacuum.

description: We investigate extreme value theory for physical systems with a global conservation law which describe renewal processes, mass transport models and long-range interacting spin models. As shown previously, a special feature is that the distribution of the extreme value exhibits a non-analytical point in the middle of the support. We expose exact relationships between constrained extreme value theory and well-known quantities of the underlying stochastic dynamics, all valid beyond the midpoint in generality, i.e. even far from the thermodynamic limit. For example for renewal processes, the distribution of the maximum time between two renewal events is exactly related to the mean number of these events. In the thermodynamic limit, we show how our theory is suitable to describe typical and rare events which deviate from classical extreme value theory. For example for the renewal process, we unravel dual scaling of the extreme value distribution, pointing out two types of limiting laws: a normalisable scaling function for the typical statistics and a non-normalised state describing the rare events.

description: Owing to advancements in deep learning technology, Vision Transformers (ViTs) have demonstrated impressive performance in various computer vision tasks. Nonetheless, ViTs still face some challenges, such as high computational complexity and the absence of desirable inductive biases. To alleviate these issues, {the potential advantages of combining eagle vision with ViTs are explored. We summarize a Bi-Fovea Visual Interaction (BFVI) structure inspired by the unique physiological and visual characteristics of eagle eyes. A novel Bi-Fovea Self-Attention (BFSA) mechanism and Bi-Fovea Feedforward Network (BFFN) are proposed based on this structural design approach, which can be used to mimic the hierarchical and parallel information processing scheme of the biological visual cortex, enabling networks to learn feature representations of targets in a coarse-to-fine manner. Furthermore, a Bionic Eagle Vision (BEV) block is designed as the basic building unit based on the BFSA mechanism and BFFN. By stacking BEV blocks, a unified and efficient family of pyramid backbone networks called Eagle Vision Transformers (EViTs) is developed. Experimental results show that EViTs exhibit highly competitive performance in various computer vision tasks, such as image classification, object detection and semantic segmentation. Compared with other approaches, EViTs have significant advantages, especially in terms of performance and computational efficiency. Code is available at https://github.com/nkusyl/EViT

description: Foundation models (FM) have demonstrated remarkable performance across a wide range of tasks (especially in the fields of natural language processing and computer vision), primarily attributed to their ability to comprehend instructions and access extensive, high-quality data. This not only showcases their current effectiveness but also sets a promising trajectory towards the development of artificial general intelligence. Unfortunately, due to multiple constraints, the raw data of the model used for large model training are often inaccessible, so the use of end-to-end models for downstream tasks has become a new research trend, which we call Learn From Model (LFM) in this article. LFM focuses on the research, modification, and design of FM based on the model interface, so as to better understand the model structure and weights (in a black box environment), and to generalize the model to downstream tasks. The study of LFM techniques can be broadly categorized into five major areas: model tuning, model distillation, model reuse, meta learning and model editing. Each category encompasses a repertoire of methods and strategies that aim to enhance the capabilities and performance of FM. This paper gives a comprehensive review of the current methods based on FM from the perspective of LFM, in order to help readers better understand the current research status and ideas. To conclude, we summarize the survey by highlighting several critical areas for future exploration and addressing open issues that require further attention from the research community.

description: One of the leading food retail chains, ‘Spencers’ have established backward linkages with farmers for procuring fresh fruits and vegetables. The main strategy of this system ensures a steady and continuous supply of fresh vegetables to the food retail chain and flow of income to farmers. This linkage has been able to change the method of farming and the marketing arrangement followed by the food retail chains. The marketing arrangement by Spencers food retail chain has reduced the market risks and transaction cost of farmers and has helped them in breaking away from the clutches of traditional brokers/wholesalers/commission agents. Direct supply by farmers has allowed the retail chain to simultaneously increase control over quality, supply reliability and price stability. An added advantage of this model is that it provides flexibility to the farmers to exit from this system, if they are not satisfied with its functioning, since there are no written contracts. This model of linkage is specially suited to small and marginal farmers and improves their economic conditions by providing an opportunity to grow and supply high-value vegetables round the year at a fairly decent price. The study has analyzed the impact of food retail chain linkage on farmers.

description: A field theory is proposed where the regular fermionic matter and the dark fermionic matter are different states of the same "primordial" fermion fields. In regime of the fermion densities typical for normal particle physics, each of the primordial fermions splits into three generations identified with regular fermions. In a simple model, this fermion families birth effect is accompanied with the right lepton numbers conservation laws. It is possible to fit the muon to electron mass ratio without fine tuning of the Yukawa coupling constants. When fermion energy density becomes comparable with dark energy density, the theory allows new type of states - Cosmo-Low Energy Physics (CLEP) states. Neutrinos in CLEP state can be both a good candidate for dark matter and responsible for a new type of dark energy. In the latter case the total energy density of the universe is less than it would be in the universe free of fermionic matter at all. The (quintessence) scalar field is coupled to dark matter but its coupling to regular fermionic matter appears to be extremely suppressed.

description: The study has estimated the extent of investment made in promotion of marketing infrastructure in the country and growth in public and private investments. It has also examined state-wise spread of private and public investments in agricultural marketing infrastructure, its composition and share and has investigated whether private investment induces pubic investment or vice versa. Of the total investment of Rs 157652.30 lakh made for the development of agricultural marketing infrastructure, Madhya Pradesh has accounted for the maximum (36%) share, followed by Tamil Nadu (18%) and Andhra Pradesh (13.5%). West Bengal has accounted for the lowest share. The analysis has indicated that there is a strong complementarity between private and public investments and as soon as private investment comes, public investment also starts pouring in. On investigating whether public investment is dependent on private investment or vice versa, the study has revealed that private investment induces public investment. The study has further indicated that in agricultural marketing infrastructure, private investment has taken a lead, which is a welcome change because private investment is more efficiently used as compared to public investment. To give further fillip to private investment in agricultural marketing infrastructure, the study has provided certain suggestions.

description: Linear temperature dependence of transport coefficients in metals is often ascribed to non-Fermi-liquid physics. Here we demonstrate the $T$-linear behavior of nonlocal conductivity in a clean 2D electron fluid, where carrier collisions assist conduction and lead to hydrodynamic transport with conductance rather than resistance growing with temperature. The key aspect is the occurrence of multiple hydrodynamic modes representing odd-parity modulations of the Fermi surface evolving in space and time. A cascade of such modes results in a linear $T$ dependence that extends to lowest temperatures, as well as a Kolmogorov-like fractional power $-5/3$ scaling of conductivity vs. wavenumber. These dependences provide a smoking gun for nonclassical hydrodynamics driven by such modes, expected to be generic for 2D electron fluids with simple near-circular Fermi surfaces.

description: Searches for young gas giant planets at wide separations have so far focused on techniques appropriate for compact (Jupiter sized) planets. Here we point out that protoplanets born through Gravitational Instability (GI) may remain in an initial pre-collapse phase for as long as the first $ 10^5-10^7$ years after formation. These objects are hundreds of times larger than Jupiter and their atmospheres are too cold ($T\sim$ tens of K) to emit in the NIR or H$α$ via accretion shocks. However, it is possible that their dust emission can be detected with ALMA, even around Class I and II protoplanetary discs. In this paper we produce synthetic observations of these protoplanets. We find that making a detection in a disc at 140 parsecs would require a few hundred minutes of ALMA band 6 observation time. Protoplanets with masses of 3-5 $M_J$ have the highest chance of being detected; less massive objects require unreasonably long observation times (1000 minutes) while more massive ones collapse into giant planets before $10^5$ years. We propose that high resolution surveys of young ($10^5-10^6$ years), massive and face on discs offer the best chance for observing protoplanets. Such a detection would help to place constraints on the protoplanet mass spectrum, explain the turnover in the occurrence frequency of gas giants with system metallicity and constrain the prevalence of GI as a planet formation mechanism. Consistent lack of detection would be evidence against GI as a common planet formation mechanism.

description: Physical infrastructure development is a powerful means of promoting economic growth as (i) it creates production facilities, “crowds in” private investment and thereby stimulates economic activities, (ii) reduces transaction and marketing costs, improving competitiveness, and (iii) provides employment opportunities to the poor. Rural Infrastructure Development Fund (RIDF) supported irrigation projects help provide the necessary impetus for infrastructure development, thereby aiding in capital formation. Evaluation of irrigation investments under RIDF in the states of Uttar Pradesh, Haryana, Orissa, Maharashtra and Assam has revealed that the investments are economically viable. The net benefits realised by the user community from the investments in irrigation have been found fairly high, except in Orissa and Uttar Pradesh. Full benefits of medium irrigation projects in Uttar Pradesh could not be realised due to pending rehabilitation work and scanty rainfall. Similarly, non-completion of canal works in Orissa has adversely affected the returns to investment. The study has observed that adequate maintenance through budgetary provisions and/or through levying of user charges would ensure sustainability of benefits. It has suggested that creation of Water Users Associations (WUAs), envisaged under RIDF, would help in effective water distribution, maintenance and collection of water charges.

description: The major goal of high-energy heavy-ion collisions is to study the properties of the deconfined quark gluon plasma (QGP), such as partonic collectivity. The collective motion of constituent quarks can be derived from the anisotropic flow measurements of identified hadrons within the coalescence framework. Based on published results of elliptic flow ($v_2$), we shall test the coalescence sum rule using $K^{\pm}$, $p$, ${\bar p}$, $Λ$ and ${\bar Λ}$, and further extract $v_2$ values for produced $u$($d$, $\bar u$, $\bar d$), $s$ and $\bar s$ quarks, as well as transported $u(d)$ quarks in 10-40\% Au+Au collisions at $\sqrt{s_{\rm NN}}=$ 7.7, 11.5, 14.5, 19.6, 27, 39 and 62.4 GeV. We also attempt to link the $v_2$ difference between $π^-$ and $π^+$ to the different numbers of $u$ and $d$ quarks in the initial gold ions, and to relate the $v_2$ measurements of multi-strange hadrons to the formation times of $ϕ$, $Ω^\pm$ and $Ξ^+$.

This new method is applicable to a broad range of stochastic dynamical models, and can be implemented without severe computational demands. A simple nonlinear dynamical model is found that describes a measured blood pressure time-series in the primary frequency band of the CR dynamics. The accuracy of the method is investigated using surrogate data with parameters close to the parameters inferred in the experiment. The connection of the inferred model to a well-known beat-to-beat model of the baroreflex is discussed.

description: We present a measurement of the Cabibbo-Kobayashi-Maskawa matrix element |Vcb| based on a sample of about 53,700 B0bar --> D*+ l- nubar_l decays observed by the BaBar detector. We obtain the branching fraction averaged over l = e, mu, BR(B0bar --> D*+ l- nubar_l) = (4.90 +- 0.07(stat.) +0.36-0.35(syst.))%. We measure the differential decay rate as a function of w, the relativistic boost gamma of the D*+ in the B0bar rest frame. By extrapolating dGamma/dw to the kinematic limit w --> 1, we extract the product of |Vcb| and the axial form factor A_1(w=1). We combine this measurement with a lattice QCD calculation of A_1(w=1) to determine |Vcb| = (38.7 +- 0.3(stat.) +- 1.7(syst.) +1.5-1.3(theory)) * 10^-3.

description: Two classes of fractional type variable weights are established in this paper. The first kind of weights ${A_{\vec p( \cdot ),q( \cdot )}}$ are variable multiple weights, which are characterized by the weighted variable boundedness of multilinear fractional type operators, called multilinear Hardy--Littlewood--Sobolev theorem on weighted variable Lebesgue spaces. Meanwhile, the weighted variable boundedness for the commutators of multilinear fractional type operators are also obtained. This generalizes some known work, such as Moen (2009), Bernardis--Dalmasso--Pradolini (2014), and Cruz-Uribe--Guzmán (2020). Another class of weights ${\mathbb{A}_{p( \cdot ),q(\cdot)}}$ are variable matrix weights that also characterized by certain fractional type operators. This generalize some previous results on matrix weights ${\mathbb{A}_{p( \cdot )}}$.

The validity of the method is demonstrated for Ba(x)Sr(1-x)TiO3 system being a typical example of ferroelectric solid solution. Its phase diagram is determined using experimental data for the coefficients in the phenomenological potentials of SrTiO3 and BaTiO3. In the phase diagram of the Ba(x)Sr(1-x)TiO3 system for small Ba concentration, there are a tricritical point and two multiphase points one of which is associated with up to 6 possible phases.

description: The recent measurements of lepton flavor university (LFU) violating observables in semileptonic $b \to c \ell \barν $ and $b\to s\ell^+ \ell^-$ transitions by various experiments exhibit $(2-3)σ$ deviations from their corresponding Standard Model (SM) predictions. These tantalizing signals hint towards the possible role of new physics (NP) in $b \to c τ\barν$ and $b\to sμ^+μ^-$ decay channels. This in turn indicates that the same class of NP as appeared in $b \to c τ\barν$, might also show up in other tree level processes involving $b \to u τ\barν$ transition. Since these charged current transitions are doubly Cabibbo suppressed, the NP contributions could be significant enough leading to sizeable effects in some of the observables. In this paper, we study the implications of the vector leptoquark $U_1(3,1,2/3)$, which is one of the few scenarios that can simultaneously explain the LFU violation signals both in the charged-current as well as neutral-current sectors, on the semileptonic decays $B \to (π, ρ, ω)τ\barν$ and $B_s \to (K, K^*) τ\barν$. In particular, we pay our attention to the branching fraction, lepton flavor non-universality (LNU) observable, forward-backward asymmetry and the polarization asymmetry parameters of these modes. We find substantial deviations in the branching fractions as well as LNU observables of these decay modes due to the $U_1$ contributions, which can be probed by the currently running experiments LHCb and Belle-II.

description: We investigate the asymptotics of the determinant of N by N Hankel matrices generated by Fisher-Hartwig symbols defined on the real line, as N becomes large. Such objects are natural analogues of Toeplitz determinants generated by Fisher-Hartwig symbols, and arise in random matrix theory in the investigation of certain expectations involving random characteristic polynomials. The reduced density matrices of certain one-dimensional systems of impenetrable bosons can also be expressed in terms of Hankel determinants of this form. We focus on the specific cases of scaled Hermite and Laguerre weights. We compute the asymptotics using a duality formula expressing the N by N Hankel determinant as a 2|q|-fold integral, where q is a fixed vector, which is valid when each component of q is natural.We thus verify, for such q, a recent conjecture of Forrester and Frankel derived using a log-gas argument.

description: We show that vacuum string field theory with the singular kinetic operator conjectured by Gaiotto, Rastelli, Sen and Zwiebach can be obtained by field redefinition from a regular theory constructed by Takahashi and Tanimoto. We solve the equation of motion both by level truncation and by a series expansion using the regulated butterfly state, and we find evidence that the energy density of a D25-brane is well defined and finite. Although the equation of motion naively factorizes into the matter and ghost sectors in the singular limit, subleading terms in the kinetic operator are relevant and the factorization does not strictly hold. Nevertheless, solutions corresponding to different D-branes can be constructed by changing the boundary condition in the boundary conformal field theory formulation of string field theory, and ratios of D-brane tensions are shown to be reproduced correctly.

description: In view of the importance of rural credit to agriculture and rural development, this paper has examined a few structural constraints that hamper the credit delivery and has discussed some of the measures taken to improve the situation. The public policy on rural credit in India has been focussed on institutionalisation as a means of providing cheaper credit to farmers. As a result, the share of private moneylenders has decreased substantially from 93 per cent in early-1950s to 31 per cent by 1991. Disturbingly enough, they have emerged as an important source, more so for the resource-poor with a share of 39 per cent by 2002. The multiagency system onset for giving a wide choice to farmers has turned out to be ineffective due to deficiencies of design and architecture. Also, ailing cooperatives, backtracked RRBs and commercial banks with waning interest in rural credit have contributed to the ineffectiveness of the multiagency system, hampering the credit delivery. Several measures have been taken to revitalise the system from time to time. Cooperatives are being given a package assistance for revival following the Vaidyanathan Committee Report. RRBs have been amalgamated and are being given capital to cleanse up their balance sheets. Commercial banks have been successfully involved in ‘Farm Credit Package’ for doubling the credit and other initiatives of Government of India. The SHG-bank linkage has been promoted on a large scale to supplement rural credit delivery. But, its high transaction costs make it a costly alternative, especially when the business is handled solely by NGOs/MFIs. A thorough overhauling of the rural credit system and its restructuring is the need of the hour. However, it cannot be effective if done alone in isolation without revitalising the Indian agriculture itself.
title: Des airs de parole : du son et du rythme aux représentations symboliques de la musicalité intrinsèque à la langue

description: Cet article présente une synthèse des principales dimensions impliquées par les recherches s’intéressant à la question des informations véhiculées par la musicalité intrinsèque à la langue. De par ses propriétés segmentales et prosodiques, chaque langue possède une empreinte sonore et rythmique qui lui est spécifique. Cette contribution examine, à travers le parallèle à la musique, différents aspects qui contribuent à dépeindre cette musicalité intrinsèque, et tente de cerner les rôles variés que celle-ci peut servir. Les éléments sonores, au-delà même du sens qu’ils dénotent, se posent dans cette perspective tant comme repère incontournable de l’accès au sens (notamment dans l’acquisition de la langue maternelle et l’apprentissage des langues étrangères), que comme manifestation musicale et esthétique. Comme l’illustrent des études récentes rendant compte de situations de contact entre langue et musique, la frontière entre fonctions linguistiques et substance musicale est parfois difficile à délimiter, et s’atténue dans certains contextes au point de voir la musique venir prolonger l’usage de la parole.

description: We consider the problem of asymptotic stability of a self-similar attractor for a simple semilinear radial wave equation which arises in the study of the Yang-Mills equations in 5+1 dimensions. Our analysis consists of two steps. In the first step we determine the spectrum of linearized perturbations about the attractor using a method of continued fractions. In the second step we demonstrate numerically that the resulting eigensystem provides an accurate description of the dynamics of convergence towards the attractor.

description: The study has conducted the micro level analysis of hatchery operators, fishseed-rearing farmers and carp farmers with respect to their socio-economic characteristics, infrastructural development, husbandry practices and economics returns, based on the survey and on-farm trial data collected by the research partners in six Asian countries, viz. Bangladesh, China, India, Indonesia, Thailand and Vietnam. The genetically-improved carp strain is economically viable and socially acceptable. The attractive profits to hatchery operators and nursery and carp farmers have created conducive environment for the dissemination of improved carp strain. Price policy models for improved strains have been developed. The premium price for fingerlings and broodstock with improved strain has been assessed. The high price of genetically-improved nuclear seed and broodstock would build self-supportive research and extension systems in the country. A business plan for Jayanti rohu has been worked out, as an example for replacement of rohu by Jayanti rohu.

description: We show that many large cardinal notions up to measurability can be characterized through the existence of certain filters for small models of set theory. This correspondence will allow us to obtain a canonical way in which to assign ideals to many large cardinal notions. This assignment coincides with classical large cardinal ideals whenever such ideals had been defined before. Moreover, in many important cases, relations between these ideals reflect the ordering of the corresponding large cardinal properties both under direct implication and consistency strength.

description: The complex chemistry that occurs in star-forming regions can provide insight into the formation of prebiotic molecules at various evolutionary stages of star formation. To study this process, we present millimeter-wave interferometric observations of the neighboring hot cores W3(H$_2$O) and W3(OH) carried out using the NOEMA interferometer. We have analyzed distributions of six molecules that account for most observed lines across both cores and have constructed physical parameter maps for rotational temperature, column density, and velocity field with corresponding uncertainties. We discuss the derived spatial distributions of these parameters in the context of the physical structure of the source. We propose the use of HCOOCH$_3$ as a new temperature tracer in W3(H$_2$O) and W3(OH) in addition to the more commonly used CH$_3$CN. By analyzing the physically-derived parameters for each molecule across both W3(H$_2$O) and W3(OH), the work presented herein further demonstrates the impact of physical environment on hot cores at different evolutionary stages.

On explicit solutions to the stationary axisymmetric Einstein-Maxwell equations describing dust disks
Creators: name: Klein, C.
Publisher: name: arXiv
Year: 2005
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We review explicit solutions to the stationary axisymmetric Einstein-Maxwell equations which can be interpreted as disks of charged dust. The disks of finite or infinite extension are infinitesimally thin and constitute a surface layer at the boundary of an electro-vacuum. The Einstein-Maxwell equations in the presence of one Killing vector are obtained by using a projection formalism. The SU(2,1) invariance of the stationary Einstein-Maxwell equations can be used to construct solutions for the electro-vacuum from solutions to the pure vacuum case via a so-called Harrison transformation. It is shown that the corresponding solutions will always have a non-vanishing total charge and a gyromagnetic ratio of 2. Since the vacuum and the electro-vacuum equations in the stationary axisymmetric case are completely integrable, large classes of solutions can be constructed with techniques from the theory of solitons. The richest class of physically interesting solutions to the pure vacuum case due to Korotkin is given in terms of hyperelliptic theta functions. The Harrison transformed hyperelliptic solutions are discussed.

description: Stellar cooling arguments place strict restrictions on a wide variety of models of new physics. In this paper, we argue that mechanisms to evade these constraints are restricted by thermodynamic arguments, then present a minimal model extension that allows new particles to evade all stellar constraints. In doing this, we demonstrate that interesting parameter space can be reopened, using the EDGES signal and Xenon1T excess as examples. This mechanism highlights the importance of laboratory experiments in a well-controlled environment to search for new physics, complementary to astrophysical searches.

description: The asymptotic dimension of metric spaces is an important notion in geometric group theory introduced by Gromov. The metric spaces considered in this paper are the ones whose underlying spaces are the vertex-sets of graphs and whose metrics are the distance functions in graphs. A standard compactness argument shows that it suffices to consider the asymptotic dimension of classes of finite graphs. In this paper we prove that the asymptotic dimension of any proper minor-closed family, any class of graphs of bounded tree-width, and any class of graphs of bounded layered tree-width are at most 2, 1, and 2, respectively. The first result solves a question of Fujiwara and Papasoglu; the second and third results solve a number of questions of Bonamy, Bousquet, Esperet, Groenland, Pirot and Scott. These bounds for asymptotic dimension are optimal and improve a number of results in the literature. Our proofs can be transformed into linear or quadratic time algorithms for finding coverings witnessing the asymptotic dimension which is equivalent to finding weak diameter colorings for graphs. The key ingredient of our proof is a unified machinery about the asymptotic dimension of classes of graphs that have tree-decompositions of bounded adhesion over hereditary classes with known asymptotic dimension, which might be of independent interest.
