description: It is now generally accepted that the approach of enlarging state-based social security systems in developing countries in order to achieve universal coverage has failed. It is the poor and rural population in particular who are largely excluded from any kind of social insurance. This paper reviews the literature to identify the major reasons for state and market failure, describes the existing systems and their institutional strengths and weaknesses and analyses the possibilities for a public-private partnership. To this end, the paper identifies four main providers of social security, namely the state, the market, member-based organisations, and the private households.Whereas the reasons for state failure – inadequate and inefficient programmes to deal with the socio-economic realities – and market failure - information problems and high transaction costs- have been analysed in great detail, there is controversy over how adequately member and private household-based systems can protect members against basic risks such as illness, disability, accidents and death. Several empirical studies in rural areas have shown the limits of traditional insurance arrangements, which basically provide insufficient coverage against co-variate risks while entailing high costs in terms of pursuing less risky activities. Moreover, these systems are under heavy pressure from change in the socio-economic environment, such as market penetration and population growth. Given this situation, the paper explores the possibilities of a public-private partnership that are created by exploiting local information, on the one hand, while enhancing the possibilities of risk pooling, reinsurance and better access to risk capital, on the other. However, a successful partnership depends on several factors. The ones identified and discussed here are the willingness of the state to withdraw from certain activities and the political and economic environment required for wider private engagement in general. The paper concludes by introducing a preliminary agenda for policy action and research. Then literature survey has shown that a lot of questions about the appropriate institutional design of social security systems in rural areas remain unanswered. More research is needed to identify the population’s actual needs and its demand for insurance in a specific socio-economic context and agro-ecological zone, to analyse the economic and social impact of innovative insurance schemes recently evolving in many countries, to identify conditions for a successful private-public partnership for social security provision and finally, to find appropriate ways of translating the findings into adequate policy measures.

description: We show that the change of the fluctuation spectrum near the quantum critical point (QCP) may result in the continuous change of critical exponents with temperature due to the increase in the effective dimensionality upon approach to QCP. The latter reflects the crossover from thermal fluctuations white noise mode to the quantum fluctuations regime. We investigate the critical dynamics of an exemplary system obeying the Bose-Einstein employing the Keldysh-Schwinger approach and develop the renormalization group technique that enables us to obtain analytical expressions for temperature dependencies of critical exponents.

description: This study examines four sets of questions: What is desertification, and how can its impact on productivity be monitored? How extensive is the desertification problem in the MENA region now, and how has it changed over time? What is the current status of the water-harvesting techniques used to control desertification in the MENA region? What are the main demographic, technical, social, and economic forces driving the problem as it now exists and how will it be influenced by observable trends, particularly in Egypt? Potential policy actions and their implications are discussed against the background of what is already being done in governmental and non-governmental efforts to address the problem of desertification in the MENA region. At the same time the research explores the economics of water harvesting in the region and its potentials for expanded desert utilization. The study presents environmental data on each of the countries in the MENA region and on the region as a whole, which was collected by a satellite remote sensing system over the last 17 years. The images of the MENA region produced by the NOAA satellite showed no alarming damage to vegetation – quite the opposite: we estimated that the vegetational boundary has expanded into the desert in most of the MENA countries due to human actions.

description: This study explored the application of eye tracker technology in visual fatigue assessment, aiming to classify and predict fatigue status through nonlinear parameters. Visual fatigue is a common problem during long-term visual tasks, which has a great impact on personal health and work efficiency. In order to effectively evaluate visual fatigue, this study used eye movement data and calculated nonlinear parameters such as entropy, combined with a machine learning model for fatigue classification. In terms of methodology, we used three machine learning models: SVM, KNN, and Random Forest for comparison, and trained and verified the models based on eye movement parameters and SSQ questionnaire results. The results show that the Random Forest model performs best in classifying fatigue status with an accuracy of 0.76 and an AUC score of 0.81. The best parameter combination includes distance to center of mass(Dist_CM), fixaton count with the 10% AOI area(FC_10), and right eye Sample Entropy(RE_Entropy), showing that these parameters can effectively reflect the changes in fatigue status. The study confirmed the key role of nonlinear parameters such as entropy in the classification of visual fatigue and highlighted the potential of eye tracker technology in fatigue monitoring and management.

description: When productivity is fostered by an individual’s own human capital as well as by the economy-wide average level of human capital, individuals under-invest in human capital. A strictly positive probability of migration to a richer country raises both the level of human capital formed by optimizing individuals in the home country and the average level of human capital of non-migrants in the country. Conditions are provided under which the welfare of all workers i higher with migration than in its absence. A well-controlled, restrictive migration policy can enhance welfare and nudge the economy toward the social optimum.

description: Performing diagnosis or exploratory analysis during the training of deep learning models is challenging but often necessary for making a sequence of decisions guided by the incremental observations. Currently available systems for this purpose are limited to monitoring only the logged data that must be specified before the training process starts. Each time a new information is desired, a cycle of stop-change-restart is required in the training process. These limitations make interactive exploration and diagnosis tasks difficult, imposing long tedious iterations during the model development. We present a new system that enables users to perform interactive queries on live processes generating real-time information that can be rendered in multiple formats on multiple surfaces in the form of several desired visualizations simultaneously. To achieve this, we model various exploratory inspection and diagnostic tasks for deep learning training processes as specifications for streams using a map-reduce paradigm with which many data scientists are already familiar. Our design achieves generality and extensibility by defining composable primitives which is a fundamentally different approach than is used by currently available systems. The open source implementation of our system is available as TensorWatch project at https://github.com/microsoft/tensorwatch.

description: Value chain development is increasingly perceived as an important approach for agricultural development in developing countries. This paper uses a Rural Investment and Policy Analysis (RIAPA) model for the mainland Tanzania economy to identify the agricultural activities and value-chains whose expansion will be most effective at fostering economic development along four dimensions: generating economic growth in the agricultural-food sector of Tanzania; reducing national and rural poverty; generating employment; and improving nutrition by diversifying diets. The results of scenarios run through the model suggests that there is no single value-chain that can achieve all of the policy objectives. Instead, a more balanced portfolio of value-chains would not only enhance agriculture’s future contribution to poverty reduction and economic growth, but also promote faster rural transformation and dietary diversification, both of which are needed to create job opportunities and improve nutrition outcomes over the longer-term. The analysis suggests that vegetables, coffee, milk, cotton, nuts, and oilseeds should be considered as “priority” value-chains, because these are the most effective at achieving multiple policy objectives. Other value-chains that meet several of the development objectives considered include maize, fishing, wheat and barley, rice, cattle, and poultry and eggs.

description: We discuss the effects of particle acceleration at the bow shocks expected in the binary pulsar system J0737-3039, due to the wind from pulsar A interacting with both the interstellar medium (ISM), and with the magnetosphere of pulsar B. In this model, we find that the likeliest source for the X-rays observed by Chandra is the emission from the shocked wind of pulsar A as it interacts with the ISM. In this case, for favorable model parameter values, better statistics might help Chandra marginally resolve the source. A consequence of the model is a power law high energy spectrum extending up to $\lesssim$ 60 keV, at a level of $\sim 2 \times 10^{-13}$ erg cm$^{-2}$ s$^{-1}$.

description: Sketching, a dimensionality reduction technique, has received much attention in the statistics community. In this paper, we study sketching in the context of Newton's method for solving finite-sum optimization problems in which the number of variables and data points are both large. We study two forms of sketching that perform dimensionality reduction in data space: Hessian subsampling and randomized Hadamard transformations. Each has its own advantages, and their relative tradeoffs have not been investigated in the optimization literature. Our study focuses on practical versions of the two methods in which the resulting linear systems of equations are solved approximately, at every iteration, using an iterative solver. The advantages of using the conjugate gradient method vs. a stochastic gradient iteration are revealed through a set of numerical experiments, and a complexity analysis of the Hessian subsampling method is presented.

description: As communication moves to social media, countries are losing control over what messages are being circulated about themselves. This article explores how South Korea’s country image is reflected within this contemporary networked communication context. We argue that country images, defined as the perceptions of countries by foreign audiences, can be swayed not only by official actors engaging in public diplomacy and nation branding projects but by any internet user who contributes to a marketplace of images. Using a social listening platform, we captured all the tweets about South Korea sent from June 01, 2019 to Jan 31, 2020. Combining textual and network analyses, our study looked at the main actors, topics, and network structures that influence South Korea’s country image on Twitter. Our findings suggest that there is no unified South Korean country image, rather diverse and relatively dispersed images. We further found that official actors had limited impact on the conversations surrounding South Korea due to their insular activities. Our methodology and findings contribute to the nascent body of empirical works in country image studies.

description: El propósito de este trabajo fue desarrollar la primera parte del segundo proyecto del Programa Psiquis. En esta oportunidad, lo que se pretendió fue sentar las bases teóricas del funcionamiento de una neurona artificial única, para luego, en una segunda parte, proceder a su ensamble práctico, con otras con las mismas características para generar un Psicocito (o célula psíquica) que es la unidad funcional y operativa del aparato psíquico propuesta por la Lógica Transcursiva. Siguiendo sus lineamientos, se pudo emular el funcionamiento de una neurona natural desde el punto de vista eléctrico, mediante el uso de un software profesional (Electron®), para generar los circuitos respectivos que luego, en una segunda etapa, serán probados en una plataforma Arduino®. En esta oportunidad, luego de mostrar la existencia de sistemas naturales (amebas, hongos) que evidencian un comportamiento similar, se demuestra que cualquier neurona es a la vez, un resonador (porque puede generar ondas de una frecuencia determinada como también, seleccionar frecuencias específicas de una señal); es una unidad de aprendizaje (ya que la frecuencia es memorizada para servir a dos propósitos. Por un lado, para identificar el sistema real (biológico, psíquico o sociocultural) desde dónde viene el estímulo, y por otro, para saber en qué sistema se debe proyectar la respuesta, que obviamente es el mismo; y por último, es un sistema memristivo, es decir, con memoria, y que esta facultad de poder “retener” una historia, la ejerce sin consumir energía, lo cual aproxima aún más este desarrollo a la eficiencia que muestra nuestro cerebro, encaminando esta investigación hacia un posible cambio del paradigma actual de las neurociencias.

description: We present a theoretical study of the mesoscopic fluctuations of $g$-tensors in a metal nanoparticle. The calculations were performed using a semi-realistic tight-binding model, which contains both spin and orbital contributions to the $g$-tensors. The results depend on the product of the spin-orbit scattering time $τ_{\textrm{\small so}}$ and the mean-level spacing $δ$, but are otherwise weakly affected by the specific shape of a {\it generic} nanoparticle. We find that the spin contribution to the $g$-tensors agrees with Random Matrix Theory (RMT) predictions. On the other hand, in the strong spin-orbit coupling limit $δτ_{\textrm{\small so}}/\hbar \to 0$, the orbital contribution depends crucially on the space character of the quasi-particle wavefunctions: it levels off at a small value for states of $d$ character but is strongly enhanced for states of $sp$ character. Our numerical results demonstrate that when orbital coupling to the field is included, RMT predictions overestimate the typical $g$-factor of orbitals that have dominant $d$-character. This finding points to a possible source of the puzzling discrepancy between theory and experiment.

description: In this article, we provide a conceptual framework for the practice and study of commercial diplomacy in the light of two developments in the field of diplomacy. The first development in the field is related to the relative popularity of two new terms in diplomatic practice: public diplomacy and nation branding. The second development is the role of information and communication technologies (ICTs). Our main objective is to clear the conceptual ambiguity by demonstrating the role of commercial diplomacy in the larger framework of diplomatic practices and the interdependence of commercial diplomacy, nation branding, and public diplomacy specifically in the age of digital communications. With our model, we hope to bridge the gaps between different practices, concepts, and fields of studies.

description: A study was conducted in Malawi to assess the quality of national policy processes around agriculture and food security and the institutional framework through which they are conducted. The study involved twice administering the same survey questionnaire to a diverse set of over 50 national stakeholders on the issues. The survey was first administered in 2015 and then again in 2017/18. Overall, the initial survey showed that, while some positive developments had been achieved and elements of the policy processes were quite strong, improvements were still needed both in the quality of those processes and in the quality of the institutions involved. However, contrary to expectations, the survey completed in 2017/18 showed an increase in pessimism among respondents as to the quality of the processes and the institutions involved in them. Indices on both the quality of the processes and on the quality of the institutions had dropped significantly from the baseline survey. This result was unexpected, as policy developments around agriculture and food security in Malawi between 2015 and 2017/18 were quite positive—several important agricultural policy achievements had been realized. In addition, a 2018 biennial review on agricultural growth and transformation across Africa rated Malawi as having a strong performance on policy processes. However, Malawi also experienced recurrent widespread food insecurity crises over this period, the management of which required significant humanitarian assistance. Consequently, there is a significant disconnect between the reasonably high quality of the policy documents developed through these policy processes and the results obtained—the quality of policy implementation so far has not met the aspirations of those policies. Hence, in responding to the survey a second time, respondents were somewhat more skeptical than anticipated of the quality of the policy processes in which they are engaged. Better quality policy processes make an important, but certainly not sufficient, contribution to achieving better outcomes in Malawi’s agricultural sector and to ensuring the food security of Malawi’s citizens is optimal. Effective implementation of the policies developed through these processes also is necessary.
Quantum phase transition in a minimal model for the Kondo effect in a Josephson junction

description: We propose a minimal model for the Josephson current through a quantum dot in a Kondo regime. We start with the model that consists of an Anderson impurity connected to two superconducting (SC) leads with the gaps $Δ_α=|Δ_α| e^{i θ_α}$, where $α= L, R$ for the lead at left and right. We show that, when one of the SC gaps is much larger than the others $|Δ_L| \gg |Δ_R|$, the starting model can be mapped exactly onto the single-channel model, which consists of the right lead of $Δ_R$ and the Anderson impurity with an extra onsite SC gap of $Δ_d \equiv Γ_L e^{i θ_L}$. Here $θ_L$ and $Γ_L$ are defined with respect to the starting model, and $Γ_L$ is the level width due to the coupling with the left lead. Based on this simplified model, we study the ground-state properties for the asymmetric gap, $|Δ_L| \gg |Δ_R|$, using the numerical renormalization group (NRG) method. The results show that the phase difference of the SC gaps $ϕ\equiv θ_R -θ_L$, which induces the Josephson current, disturbs the screening of the local moment to destabilize the singlet ground state typical of the Kondo system. It can also drive the quantum phase transition to a magnetic doublet ground state, and at the critical point the Josephson current shows a discontinuous change. The asymmetry of the two SC gaps causes a re-entrant magnetic phase, in which the in-gap bound state lies close to the Fermi level.

description: Additional file 7 Figure S5. Core genome alignement-based ML phylogeny of S. Napoli genomes. Core genome alignment was used for phylogenetic reconstruction using RAxML (version 7.2.8, [27]) with bootstrapping and Maximum Likelihood (ML) search under the GAMMA model of rate heterogeneity. Tree visualization was obtained using FigTree v1.4.4 [28]. Within S. Napoli serovar, samples cluster primarily by ST, and divide into two major subclades. No significant correlation could be found between phylogenetic clustering and source of isolation. Here source of isolation is shown as a colour scale.

description: Let $GL_M$ be general linear Lie group over the complex field. The irreducible rational representations of the group $GL_M$ are labeled by pairs of partitions $μ$ and $\tildeμ$ such that the total number of non-zero parts of $μ$ and $\tildeμ$ does not exceed $M$. Let $U$ be the representation of $GL_M$ corresponding to such a pair. Regard the direct product $GL_N\times GL_M$ as a subgroup of $GL_{N+M}$. Let $V$ be the irreducible rational representation of the group $GL_{N+M}$ corresponding to a pair of partitions $λ$ and $\tildeλ$. Consider the vector space $W=Hom_{G_M}(U,V)$. It comes with a natural action of the group $GL_N$. Let $n$ be sum of parts of $λ$ less the sum of parts of $μ$. Let $\tilde{n}$ be sum of parts of $\tildeλ$ less the sum of parts of $\tildeμ$. For any choice of two standard Young tableaux of skew shapes $λ/μ$ and $\tildeλ/\tildeμ$ respectively, we realize $W$ as a subspace in the tensor product of $n$ copies of the defining $N$-dimensional representation of $GL_N$, and of $\tilde{n}$ copies of the contragredient representation. This subspace is determined as the image of a certain linear operator $F$ in the tensor product, given by explicit multiplicative formula. When M=0 and $W=V$ is an irreducible representation of $GL_N$, we recover the classical realization of $V$ as a subspace in the space of all traceless tensors. Then the operator $F$ can be regarded as the rational analogue of the Young symmetrizer, corresponding to the chosen standard tableau of shape $λ$. Even in the special case M=0, our formula for the operator $F$ is new. Our results are applications of representation theory of the Yangian of the Lie algebra $gl_N$.

description: We report new simultaneous X-ray and radio continuum observations of 3FGL J0427.9-6704, a candidate member of the enigmatic class of transitional millisecond pulsars. These XMM-Newton and Australia Telescope Compact Array observations of this nearly edge-on, eclipsing low-mass X-ray binary were taken in the sub-luminous disk state at an X-ray luminosity of ~10^33(d/2.3kpc)^2 erg/s. Unlike the few well-studied transitional millisecond pulsars, which spend most of their disk state in a characteristic high or low accretion mode with occasional flares, 3FGL J0427.9-6704 stayed in the flare mode for the entire X-ray observation of ~20 hours, with the brightest flares reaching ~2*10^34 erg/s. The source continuously exhibited flaring activity on time-scales of ~10-100 sec in both the X-ray and optical/UV. No measurable time delay between the X-ray and optical/UV flares is observed, but the optical/UV flares last longer, and the relative amplitudes of the X-ray and optical/UV flares show a large scatter. The X-ray spectrum can be well-fit with a partially-absorbed power-law (Gamma~1.4-1.5), perhaps due to the edge-on viewing angle. Modestly variable radio continuum emission is present at all epochs, and is not eclipsed by the secondary, consistent with the presence of a steady radio outflow or jet. The simultaneous radio/X-ray luminosity ratio of 3FGL J0427.9-6704 is higher than any known transitional millisecond pulsars and comparable to that of stellar-mass black holes of the same X-ray luminosity, providing additional evidence that some neutron stars can be as radio-loud as black holes.

Τρισδιάστατη εκτύπωση

description: Στην συγκεκριμένη εργασία έγινε ανάλυση των μηχανικών ιδιοτήτων πολυμερών δοκιμίων τα οποία υποβλήθηκαν σε κάμψη μετατρέποντας συγκεκριμένες τιμές παραμέτρων κατά τη διαδικασία εκτύπωσης τους. Η δημιουργία των δοκιμίων στηρίχθηκε στην τρισδιάστατη εκτύπωση τεχνολογίας FDM (Fused Deposition Modeling) .Η συγκεκριμένη τεχνολογία στηρίζεται στην τήξη και την επιλεκτική εναπόθεση μιας λεπτής ίνας θερμοπλαστικού για τον σχηματισμό αλλεπάλληλων στρώσεων όπου και σχηματίζεται το οριστικό αντικείμενο. Ο σχεδιασμός του πειράματος (DOE) έγινε με βάση την ορθογωνική συστοιχία Taguchi. Τα δοκίμια διαμορφώθηκαν βάσει τεσσάρων παραγόντων (ταχύτητα εκτύπωσης, θερμοκρασία εξωθητή, μοτίβο γεμίσματος, τρόπος εκτύπωσης). Πρωταρχικός στόχος της εργασίας αυτής είναι η επιλογή δοκιμίου με τις βέλτιστες μηχανικές ιδιότητες αλλά και με την μικρότερη δυνατή χρήση υλικού. Για την επιλογή του βέλτιστου συνδυασμού παραμέτρων και τον εντοπισμό του δοκιμίου με τις καλύτερες συνατές μηχανικές ιδιότητες απαιτήθηκαν 81 ξεχωριστοί συνδυασμοί και συγκεκριμένα από 9 δοκίμια με 4 διαφορετικές παραμέτρους και από 3 τιμές της κάθε παραμέτρος 81(3^4). Η σύγκριση των αποτελεσμάτων έγινε με χρήση προγράμματος στατιστικής ανάλυσης και το δοκίμιο που επιλέχθηκε ως βέλτιστο είχε τη μέγιστη παραμόρφωση και τη μέγιστη αντοχή σε κάμψη τριών σημείων. Εν κατακλείδη, από την ανάλυση δεδομένων κατέστη σαφές πως κάθε παράμετρος επιδρά διαφορετικά στις μηχανικές ιδιότητες.

description: We give the first exact determinantal formula for the resultant of an unmixed sparse system of four Laurent polynomials in three variables with arbitrary support. This follows earlier work by the author on exact formulas for bivariate systems and also uses the exterior algebra techniques of Eisenbud and Schreyer. Along the way we will prove an interesting new vanishing theorem for the sheaf cohomology of divisors on toric varieties. This will allow us to describe some supports in four or more variables for which determinantal formulas for the resultant exist.

description: Accurate determination of stellar rotation periods is important for estimating stellar ages as well as for understanding stellar activity and evolution. While for about thirty thousand stars in the Kepler field rotation periods can be determined, there are over hundred thousand stars, especially with low photometric variability and irregular pattern of variations, for which rotational periods are unknown. Here, we investigate the effect of metallicity on the detectability of rotation periods. This is done by synthesising light curves of hypothetical stars, which are identical to our Sun, with the exception of the metallicity. These light curves are then used as an input to the period determination algorithms. We find that the success rate for recovering the rotation signal has a minimum close to the solar metallicity value. This can be explained by the compensation effect of facular and spot contributions. In addition, selecting solar-like stars with near-solar effective temperature, near solar photometric variability, and with metallicity between M/H = -0.35 and M/H = 0.35 from the Kepler sample, we analyse the fraction of stars for which rotational periods have been detected as a function of metallicity. In agreement with our theoretical estimate we found a local minimum for the detection fraction close to the solar metallicity. We further report rotation periods of 87~solar-like Kepler stars for the first time.

description: We consider the quantum inverse scattering method for several mixed integrable models based on the rational SU(N) R-matrix with general toroidal boundary conditions. This includes systems whose Hilbert spaces are invariant by the discrete representations of the group SU(2) and the non-compact group SU(1,1) as well as the conjugate representation of the SU(N) symmetry. Introducing certain transformations on the quantum spaces we are able to solve generalizaed impurity problems including those related to singular matrices.
