description: Using graviton correlator on deSitter (dS) brane in 5d AdS or dS bulk we calculate the four-dimensional Newton potential. For flat brane in AdS bulk the Randall-Sundrum result is recovered. For flat brane in dS bulk the sign of subleading ($1/r^3$) term in Newton potential is negative if compare with AdS bulk. In accordance with dS/CFT correspondence this indicates that dual CFT should be non-unitary (for example, higher derivative conformal theory).

description: Social networks play a vital role in generating social learning and information exchange that can drive the diffusion of new financial innovations. This is articularly relevant for developing countries where education, extension and financial information services are underprovided. The recent introduction of mobile money in Africa represents a case where imperfect financial markets, weak extension services and information asymmetries limit the ability of rural households to make informed decisions to take advantage of mobile money innovation. This article identifies the role of social networks in the adoption of mobile money in Uganda. Using data from a survey of 477 rural households, a probit model is estimated controlling for household characteristics, correlated effects, and other possible information sources. Results suggest that learning within social networks helps disseminate information about mobile money and has enhanced its adoption. Compared to poor households, non-poor households rely more on social networks for information about mobile money. Mobile money adoption is likely to be enhanced if promotion programs reach more social networks.

description: The formulation and evaluation of projects, is a useful tool for all those who choose to carry out investment idea. To evaluate the technical and economic feasibility of commercial production of Hass avocado in a southern region of the State of Mexico, was formulated and assessed a proposed investment by investment project methodology. For analysis, the information was obtained in 2012, year of starting the project, the horizon was seven years. It includes an analysis of commercial viability, technical, financial and economic, where it was considered only contribution of partners. In addition, we performed sensitivity analysis of 11 independent variables and their effect, under a pessimistic scenario and one optimistic relative to the baseline scenario, the behavior of the profitability indicators: NPV, IRR, RSI, ID, RB/C and PR also incorporated risk analysis on indicators NPV, IRR and RB/C. The results indicated that, under certainty and, using a MARR of 12.7%, the NPV was 15368.8 thousand pesos, the IRR of 41.9%, RSI 2.9, ID 1.9 ,RB/C 2.2 and a PR of 4.04 years. Meanwhile, low uncertainty and a pessimistic scenario, the project remains profitable. The risk analysis indicated a higher than average probability of 80% that the profitability indicators reach the value obtained. In the conditions set, indicators exceeded their critical values without and with uncertainty, so the project is profitable and suggested its implementation.

description: Imitation learning is an intuitive approach for teaching motion to robotic systems. Although previous studies have proposed various methods to model demonstrated movement primitives, one of the limitations of existing methods is that the shape of the trajectories are encoded in high dimensional space. The high dimensionality of the trajectory representation can be a bottleneck in the subsequent process such as planning a sequence of primitive motions. We address this problem by learning the latent space of the robot trajectory. If the latent variable of the trajectories can be learned, it can be used to tune the trajectory in an intuitive manner even when the user is not an expert. We propose a framework for modeling demonstrated trajectories with a neural network that learns the low-dimensional latent space. Our neural network structure is built on the variational autoencoder (VAE) with discrete and continuous latent variables. We extend the structure of the existing VAE to obtain the decoder that is conditioned on the goal position of the trajectory for generalization to different goal positions. Although the inference performed by VAE is not accurate, the positioning error at the generalized goal position can be reduced to less than 1~mm by incorporating the projection onto the solution space. To cope with requirement of the massive training data, we use a trajectory augmentation technique inspired by the data augmentation commonly used in the computer vision community. In the proposed framework, the latent variables that encodes the multiple types of trajectories are learned in an unsupervised manner, although existing methods usually require label information to model diverse behaviors. The learned decoder can be used as a motion planner in which the user can specify the goal position and the trajectory types by setting the latent variables.

description: This paper presents a participatory methodological framework to identify Gross National Happiness (GNH) issues at the smallholder level in Bhutan. GNH is a development paradigm of Bhutan that has increasingly drawn international attention. Its four pillars are sustainable and equitable socioeconomic development, preservation of the environment, preservation and promotion of culture, and promotion of good governance. Since GNH is usually discussed at the national level, its domains and indicators have been defined through a top-down intellectual exercise, with possibly limited relevance of the major issues for most rural Bhutanese, which represent 69 percent of the country’s population. The methodology applied in this study was useful in identifying key GNH issues from a systems perspective at the smallholder level. Socioeconomic development and the environmental aspects were found to be the pertinent issues. The study also revealed trade-offs and dependencies among the four GNH pillars and their indicators. Inclusive policies are needed to address the concerns of smallholder farmers. If GNH is to work for the present and future generations, then it is essential to embrace the GNH issues of smallholder farmers who compose the backbone of the Bhutanese population. Further, the GNH concept is currently a mix of issues and indicators. Translating the issues identified by the study into indicators is required to properly evaluate the progress at the farm level and to support GNH policy development.

description: We present Very Large Array (VLA) observations at 1.4 GHz and 5 GHz of a sample of 12 Quasi-stellar Objects (QSOs) at z = 3.99 to 4.46. The sources were selected as the brightest sources at 250 GHz from the recent survey of Omont et al. (2001). We detect seven sources at 1.4 GHz with flux densities, S_{1.4} > 50 microJy. These centimeter (cm) wavelength observations imply that the millimeter (mm) emission is most likely thermal dust emission. The radio-through-optical spectral energy distributions for these sources are within the broad range defined by lower redshift, lower optical luminosity QSOs. For two sources the radio continuum luminosities and morphologies indicate steep spectrum, radio loud emission from a jet-driven radio source. For the remaining 10 sources the 1.4 GHz flux densities, or limits, are consistent with those expected for active star forming galaxies. If the radio emission is powered by star formation in these systems, then the implied star formation rates are of order 1e3 M_solar/year. We discuss the angular sizes and spatial distributions of the radio emitting regions, and we consider briefly these results in the context of co-eval black hole and stellar bulge formation in galaxies.

The Triplet Resonating Valence Bond State and Superconductivity in Hund's Metals

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

subject: FOS: Physical sciences

description: A central idea in strongly correlated systems is that doping a Mott insulator leads to a superconductor by transforming the resonating valence bonds (RVBs) into spin-singlet Cooper pairs. Here, we argue that a spin-triplet RVB (tRVB) state, driven by spatially, or orbitally anisotropic ferromagnetic interactions can provide the parent state for triplet superconductivity. We apply this idea to the iron-based superconductors, arguing that strong onsite Hund's interactions develop intra-atomic tRVBs between the t$_{2g}$ orbitals. On doping, the presence of two iron atoms per unit cell allows these inter-orbital triplets to coherently delocalize onto the Fermi surface, forming a fully gapped triplet superconductor. This mechanism gives rise to a unique staggered structure of onsite pair correlations, detectable as an alternating $π$ phase shift in a scanning tunnelling Josephson microscope.
Minimum energy configurations on a toric lattice as a quadratic assignment problem

description: We consider three known bounds for the quadratic assignment problem (QAP): an eigenvalue, a convex quadratic programming (CQP), and a semidefinite programming (SDP) bound. Since the last two bounds were not compared directly before, we prove that the SDP bound is stronger than the CQP bound. We then apply these to improve known bounds on a discrete energy minimization problem, reformulated as a QAP, which aims to minimize the potential energy between repulsive particles on a toric grid. Thus we are able to prove optimality for several configurations of particles and grid sizes, complementing earlier results by Bouman, Draisma and Van Leeuwaarden [ SIAM Journal on Discrete Mathematics, 27(3):1295--1312, 2013]. The semidefinite programs in question are too large to solve without pre-processing, and we use a symmetry reduction method by Parrilo and Permenter [Mathematical Programming, 181:51--84, 2020] to make computation of the SDP bounds possible.

 Lannapsyche Malicky, 1989: 11.
 Type species: Lannapsyche chantaramongkolae Malicky, 1989, original designation by monotypy.
 Type locality: Thailand.
 The species in this genus are characterized by having almost completely reduced preanal appendages (superior appendages), and a pair of sclerotized hairy pads located near the caudal margin of tergite IX. Segment X sometimes with other lobes and processes, like intermediate appendages that are not homolog with the primary segmental appendages. The preanal appendages form concave or convex setal surfaces. The mesal nodule on the first segment of the maxillary palps is present in all examined species of the genus. This nodule was not recognized and not described in the original genus diagnosis but was considered representing one of the main diagnostic characters for the Philorheithridae by Mosely (1936). The cephalic groove pattern, as well as the cephalic and thoracic setose wart pattern, appear almost identical at all examined species. The genus thus contrasts the genus Phraepsyche characterized by including species with completely different groove and wart pattern.
 Lannapsyche species rarely come to light, but can be collected at daytime along small brooks or springfed streams.

description: The concept of transaction cost has been around for more than 75 years. It has been used to explain every economic phenomenon that does not fit with standard neoclassical predictions. It has been applied to so many fields, its definition varying with every application. This paper surveys the literature on transaction costs in general, as well as those that apply transaction costs to agriculture. It focuses on the role of transaction costs in exchange in agriculture, particularly in the context of the household’s decision to engage in market exchange, in both input and output sides. The survey literature finds a confluence of definitions of transaction cost as applied to theoretical and empirical models. Coasian and Williamsonian definitions are used in interpreting fixed transaction costs while neoclassical and trade definitions (i.e., the concept of price band) characterize proportional transaction costs. The prominence of transport cost and the effect of distance and isolation in many of the analyses points to the influence of the new economic geography research stream. Measurement of transaction cost as an ad valorem tax also references the trade concept of transaction cost.

We display the role of the transverse-longitudinal admixture due to the transverse nucleon momentum. The mixing effect is appreciable at small Q^2 values, and gradually disappears at large Q^2 values. The nuclear modification is then dominated by the binding and Fermi-motion effects which are contained in the spectral function.

description: Vietnam’s economy faced difficulties in the 2006–2010 period due to the global financial crisis. The average inflation rate (>20%) was higher than the expected level (<10%) for the period. The average GDP growth rate (6.3%) was lower than the target (7.5%). In the global context, however, Vietnam’s economic growth and inflation rate were still seen as successful due to the government’s strong policy and administration interventions. Nevertheless, similar to the outcomes of the country’s other economic plans since 1986, the key “relative targets” of the plan for 2006–2010 were not successfully achieved, including that for reduced income inequality, thus restraining Vietnam’s long-term growth. The main reason is that policies implemented to achieve these goals are not at “equilibrium” quantitative points. Therefore, more investment in research that applies large-scale mathematical economics models is urgently needed, similar to the ones used widely by many other governments in the world. In addition, the government’s role in managing and developing domestic markets should be improved to protect farmers who always sell their products at prices lower than the shadow prices.

description: We consider the growth of the action for black hole spacetime with a fundamental string. Our interest is to find the difference of the behavior between black holes with three different topologies in the scenario of complexity-action conjecture. These black holes have positive, negative and zero curvatures. We would like to calculate the action growth of these systems with a probe fundamental string according to the complexity-action conjecture. We find that for the case where the black holes have the toroidal horizon structure this probe string behaves very differently from the other two cases.

description: We review the formalism of holographic renormalization. We start by discussing mathematical results on asymptotically anti-de Sitter spacetimes. We then outline the general method of holographic renormalization. The method is illustrated by working all details in a simple example: a massive scalar field on anti-de Sitter spacetime. The discussion includes the derivation of the on-shell renormalized action, of holographic Ward identities, anomalies and RG equations, and the computation of renormalized one-, two- and four-point functions. We then discuss the application of the method to holographic RG flows. We also show that the results of the near-boundary analysis of asymptotically AdS spacetimes can be analytically continued to apply to asymptotically de Sitter spacetimes. In particular, it is shown that the Brown-York stress energy tensor of de Sitter spacetime is equal, up to a dimension dependent sign, to the Brown-York stress energy tensor of an associated AdS spacetime.

description: Organic farming has been promoted and developed in Bali since 2006 by the government in collaboration with private businesses and certification bodies. This research aimed to synthesize the development of Balinese organic production as an effort toward sustainable agriculture. Data from the in-depth interview and critical review were analyzed. As of 2012, the following have been certified as organic farms: 22 groups of food crop and horticulture farms such as rice/red rice, vegetables, flowers, salak, grape, mangosteen, papaya, banana, ginger, red onion, and mushroom; 8 groups of cashew farms; and 7 groups of coffee farms. The Balinese organic production systems are potentially sustainable since the sustainability criteria were fulfilled. Many constraint factors affect organic production in Bali, including limited organic fertilizer sources, limited fresh irrigation water resource, certification budget availability, and buyers who are willing to pay a premium for organic products. Success in removing the constraint factors would pave the way for sustainable organic agriculture in Bali.

description: In India, fruits and vegetables (F&V) significantly contribute to food and nutritional security; they also enhance the livelihoods of smallholders. In recent years, demand has been increasing for these important crops, yet their productivity has been decelerating. Technical innovations can reduce yield gaps and increase the productivity of F&V crops. This paper measures technical efficiency (TE) of F&V production and its determinants based on Cobb-Douglas stochastic frontier production function. TE is defined as the maximum output that can be produced from a specified set of inputs, given the existing technology available to the farmer. The study surveyed a sample of 240 households who mostly cultivate F&V in Salem, Trichy, and Theni districts, Tamil Nadu. Mean TE level was estimated to be 0.60. The farmers in Trichy had higher TEs than those in the other districts. This means Trichy farmers use inputs more efficiently. If the average farmer in the sample could achieve the TE level of his/her most efficient counterpart, then he/she could increase output by about 34 percent with the same level of inputs. There is considerable room for increasing F&V output without additional inputs. Accessibility of irrigation facilities significantly contributed to the higher TE in Trichy. While the test for equality showed that TE did not vary significantly across farm sizes, the larger landholdings had higher TE than smaller landholdings, indicating that farm size and TE are directly related. The results showed that accessibility of infrastructure facilities (e.g., road) contributed positively to TE. Other variables such as level of education and access to credit also had positive relationship with TE.
On the double-mode RR Lyrae variables of the Sculptor dwarf galaxy

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Frequency analysis of more than 300 stars of the OGLE database on Sculptor galaxy has led to the discovery of 18 double-mode RR Lyrae (RRd) variables. This yields a 20% incidence rate for double-mode pulsation among the variables previously classified as first overtone RR Lyrae stars in this galaxy. Most of the RRd stars cover the period range of 0.47d < P_0 < 0.49d but there are two stars with longer periods of ~0.54d. All variables fit well in the pattern of the P_0 --> P_1/P_0 diagram, spanned by the RRd stars of the Galactic globular clusters and those of the Large Magellanic Cloud (LMC). It follows from our previous investigations that the luminosities and masses of the RRd stars in Galactic globular clusters and in the LMC are almost independent of metallicity. By assuming that the Sculptor RRd variables also obey this rule, with the aid of the pulsation equations we estimate their metallicities. For most of the stars we get [Fe/H]~ -1.5, which is the same value as that obtained from a semi-empirical method for the average metallicity of the fundamental mode (RRab) stars. Two RRd stars have considerably lower metallicities, but even those are within the range corresponding to the RRab stars. The narrower metallicity range of the RRd stars is in agreement with their observed luminosity range, which is about three times smaller than that of the RRab stars.

description: Freshwater gobies, particularly fry and some adult species, have been used as an alternative fishery resource. Mandulog River in Iligan City, northern Mindanao, Philippines, is one of the areas known for goby-fry fishery. This study described the potentials of the goby population in Mandulog River in terms of its fishery aspects. Households along the Mandulog River were the respondents of the survey. Results show that most of the freshwater gobies were caught as alternative food while goby-fry were sold in the market. Goby fishing was done five times a year using nets and traps. The maximum catch per fishing session was one to three kilograms and sold at more or less PHP 10 (Philippine Peso) (USD 0.23) per kilogram. Monthly income from goby fishing was from PHP 100 to PHP 200 (USD 2.35 to USD 4.71) only. Goby species such as Sicyopterus lagocephalus, Oxyeleotris lineolata, Awaous melanocephalus, A. ocellaris, Giuris margaritacea, and Rhyacichthys aspro were the preferred prey species. Findings suggest that goby fishing was not a major source of livelihood as fishers were not earning much from it. However, as a bycatch, the goby population is under threat, with their economic and ecological benefits not utilized. Destructive fishing methods such as cyanide fishing, electric fishing, and use of fine mesh nets might also adversely affect the goby population, despite being non-target species. Therefore, protection of target species from overexploitation would also benefit the goby species.

description: We modify the well-known interior penalty finite element discretization method so that it allows for element-by-element assembly. This is possible due to the introduction of additional unknowns associated with the interfaces between neighboring elements. The resulting bilinear form, and a Schur complement (reduced) version of it, are utilized in a number of auxiliary space preconditioners for the original conforming finite element discretization problem. These preconditioners are analyzed on the fine scale and their performance is illustrated on model second order scalar elliptic problems discretized with high order elements.

description: Unbiased estimates of technological parameters of an underlying production function can be obtained by first estimating a cost-share equation. From the parameter estimates of the cost share equation, it is possible to obtain all relevant elasticities, including production elasticities, own and cross input demand elasticities, the elasticity of input demand with respect to product price, and the output supply elasticities. The approach has important implications for, and represents a new way to estimate aggregate supply elasticities.

On-shell S-matrix and tachyonic effective actions

description: We evaluate various disk level four-point functions involving the massless scalar and tachyon vertex operators in the presence of background B-flux in superstring theory. By studying these amplitudes in specific limits, we find couplings of two scalars with two tachyons, and couplings of four tachyons on the world-volume of non-BPS D-branes of superstring theory. They are fully consistent with the non-commutative tachyonic Dirac-Born-Infeld effective action. They also fix the coefficient of $T^4$ term in the expansion of the tachyon potential around its maximum.

Bayesian Inference on Multivariate Medians and Quantiles

description: In this paper, we consider Bayesian inference on a class of multivariate median and the multivariate quantile functionals of a joint distribution using a Dirichlet process prior. Since, unlike univariate quantiles, the exact posterior distribution of multivariate median and multivariate quantiles are not obtainable explicitly, we study these distributions asymptotically. We derive a Bernstein-von Mises theorem for the multivariate $\ell_1$-median with respect to general $\ell_p$-norm, which in particular shows that its posterior concentrates around its true value at $n^{-1/2}$-rate and its credible sets have asymptotically correct frequentist coverage. In particular, asymptotic normality results for the empirical multivariate median with general $\ell_p$-norm is also derived in the course of the proof which extends the results from the case $p=2$ in the literature to a general $p$. The technique involves approximating the posterior Dirichlet process by a Bayesian bootstrap process and deriving a conditional Donsker theorem. We also obtain analogous results for an affine equivariant version of the multivariate $\ell_1$-median based on an adaptive transformation and re-transformation technique. The results are extended to a joint distribution of multivariate quantiles. The accuracy of the asymptotic result is confirmed by a simulation study. We also use the results to obtain Bayesian credible regions for multivariate medians for Fisher's iris data, which consists of four features measured for each of three plant species.
Do Globular Clusters Harbor Black Holes?

description: It has been firmly established that there exists a tight correlation between the central black hole mass and velocity dispersion (or luminosity) of elliptical galaxies, ``pseudobulges'' and bulges of galaxies, although the nature of this correlation still remains unclear. In this letter, we explore the possibility of extrapolating such a correlation to less massive, spherical systems like globular clusters. In particular, motivated by the apparent success in globular cluster M15, we present an estimate of the central black hole mass for a number of globular clusters with available velocity dispersion in the literature.

description: Abstract: Recently, cortical correlates of specific dream contents have been reported, such as the activation of the sensorimotor cortex during dreamed hand clenching. Yet, despite a close resemblance of such activation patterns to those seen during the corresponding wakeful behaviour, the causal mechanisms underlying specific dream contents remain largely elusive. Here, we aimed to investigate the causal role of the sensorimotor cortex in generating movement and bodily sensations during REM sleep dreaming. Following bihemispheric transcranial direct current stimulation (tDCS) or sham stimulation, guided by functional mapping of the primary motor cortex, naive participants were awakened from REM sleep and responded to a questionnaire on bodily sensations in dreams. Electromyographic (EMG) and electroencephalographic (EEG) recordings were used to quantify physiological changes during the preceding REM period. We found that tDCS, compared to sham stimulation, significantly decreased reports of dream movement, especially of repetitive actions. Other types of bodily experiences, such as tactile or vestibular sensations, were not affected by tDCS, confirming the specificity of stimulation effects to movement sensations. In addition, tDCS reduced EEG interhemispheric coherence in parietal areas and affected the phasic EMG correlation between both arms. These findings show that a complex temporal reorganization of the motor network co-occurred with the reduction of dream movement, revealing a link between central and peripheral motor processes and movement sensations of the dream self. tDCS over the sensorimotor cortex interferes with dream movement during REM sleep, which is consistent with a causal contribution to dream experience and has broader implications for understanding the neural basis of self-experience in dreams.

description: We develop X-ray Multi-modal Intrinsic-Speckle-Tracking (MIST), a form of X-ray speckle-tracking that is able to recover both the position-dependent phase shift and the position-dependent small-angle X-ray scattering (SAXS) signal of a phase object. MIST is based on combining a Fokker-Planck description of paraxial X-ray optics, with an optical-flow formalism for X-ray speckle-tracking. Only two images need to be taken in the presence of the sample, corresponding to two different transverse positions of the speckle-generating membrane, in order to recover both the refractive and local-SAXS properties of the sample. Like the optical-flow X-ray phase-retrieval method which it generalises, the MIST method implicitly rather than explicitly tracks both the transverse motion and the diffusion of speckles that is induced by the presence of a sample. Application to X-ray synchrotron data shows the method to be efficient, rapid and stable.
Unitarity and Higher-Order Corrections in Neutralino Dark Matter Annihilation into Two Photons

description: The neutralino pair annihilation into two photons in our galactic halo gives a robust dark matter signal, since it would give a quasi-monotonic gamma ray. This process is radiatively-induced, and the full-one loop calculation was done previously. However, for the heavy wino-like or Higgsino-like neutralino, the one-loop cross section violates unitarity, therefore the higher-order corrections may be important. We construct a non-relativistic theory for chargino and neutralino two-body states, and estimate all-order QED corrections and two-loop corrections by $Z$ and/or $W$ exchange. We find that the critical mass, above that the two-loop contribution is larger than one-loop one, is about 8 TeV (O(10) TeV) in the limit where neutralino is wino (Higgsino)-like, respectively. Around and above the critical mass, the all-order Z and/or W exchange must be included to estimate the cross section. On the other hand, the QED corrections depend on the mass difference between the neutralino and chargino. In the wino-like limit where neutralino is highly degenerate with chargino in mass, we find that QED corrections enhance the pair annihilation cross section by 1.5-2.

description: A polynomial form is established for the off-shell CHY scattering equations proposed by Lam and Yao. Re-expressing this in terms of independent Mandelstam invariants provides a new expression for the polynomial scattering equations, immediately valid off shell, which makes it evident that they yield the off-shell amplitudes given by massless $ϕ^3$ Feynman graphs. A CHY expression for individual Feynman graphs, valid even off shell, is established through a recurrence relation.

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.
