description: This paper studies the relationship between patience and comparative development through a combination of reduced-form analyses and model estimations. Based on a globally representative dataset on time preference in 76 countries, we document two sets of stylized facts. First, patience is strongly correlated with per capita income and the accumulation of physical capital, human capital and productivity. These correlations hold across countries, subnational regions, and individuals. Second, the magnitude of the patience elasticity strongly increases in the level of aggregation. To provide an interpretive lens for these patterns, we analyze an OLG model in which savings and education decisions are endogenous to patience, aggregate production is characterized by capital-skill complementarities, and productivity implicitly depends on patience through a human capital externality. In our model estimations, general equilibrium effects alone account for a non-trivial share of the observed amplification effects, and an extension to human capital externalities can quantitatively match the empirical evidence.

description: We introduce a novel audio processing architecture, the Open Voice Brain Model (OVBM), improving detection accuracy for Alzheimer's (AD) longitudinal discrimination from spontaneous speech. We also outline the OVBM design methodology leading us to such architecture, which in general can incorporate multimodal biomarkers and target simultaneously several diseases and other AI tasks. Key in our methodology is the use of multiple biomarkers complementing each other, and when two of them uniquely identify different subjects in a target disease we say they are orthogonal. We illustrate the methodology by introducing 16 biomarkers, three of which are orthogonal, demonstrating simultaneous above state-of-the-art discrimination for apparently unrelated diseases such as AD and COVID-19. Inspired by research conducted at the MIT Center for Brain Minds and Machines, OVBM combines biomarker implementations of the four modules of intelligence: The brain OS chunks and overlaps audio samples and aggregates biomarker features from the sensory stream and cognitive core creating a multi-modal graph neural network of symbolic compositional models for the target task. We apply it to AD, achieving above state-of-the-art accuracy of 93.8% on raw audio, while extracting a subject saliency map that longitudinally tracks relative disease progression using multiple biomarkers, 16 in the reported AD task. The ultimate aim is to help medical practice by detecting onset and treatment impact so that intervention options can be longitudinally tested. Using the OBVM design methodology, we introduce a novel lung and respiratory tract biomarker created using 200,000+ cough samples to pre-train a model discriminating cough cultural origin. This cough dataset sets a new benchmark as the largest audio health dataset with 30,000+ subjects participating in April 2020, demonstrating for the first-time cough cultural bias.

description: In [Ecological Complexity 44 (2020) Art. 100885, DOI: 10.1016/j.ecocom.2020.100885] a continuous-time compartmental mathematical model for the spread of the Coronavirus disease 2019 (COVID-19) is presented with Portugal as case study, from 2 March to 4 May 2020, and the local stability of the Disease Free Equilibrium (DFE) is analysed. Here, we propose an analogous discrete-time model and, using a suitable Lyapunov function, we prove the global stability of the DFE point. Using COVID-19 real data, we show, through numerical simulations, the consistence of the obtained theoretical results.

The test for suppressed dynamical friction in a constant density core of dwarf galaxies

description: The dynamical friction problem is a long-standing dilemma about globular clusters (hereafter,GCs) belonging to dwarf galaxies. GCs are strongly affected by dynamical friction in dwarf galaxies, and are presumed to fall into the galactic center. But, GCs do exist in dwarf galaxies generally. A solution of the problem has been proposed. If dwarf galaxies have a core dark matter halo which has constant density distribution in its center, the effect of dynamical friction will be weakened considerably, and GCs should be able to survive beyond the age of the universe. Then, the solution argued that, in a cored dark halo, the suppression of dynamical friction is caused by a new equilibrium state constructed by the interaction between the halo and the GC, in which a part of the halo rotates along with the GC (co-rotating state). In this study, I tested whether the solution is reasonable and reconsidered why a constant density, core halo suppresses dynamical friction, by means of N-body simulations. As a result, I conclude that the true mechanism of suppressed dynamical friction is not the co-rotating state, although a core halo can actually suppress dynamical friction on GCs significantly.

description: In the network security arms race, the defender is significantly disadvantaged as they need to successfully detect and counter every malicious attack. In contrast, the attacker needs to succeed only once. To level the playing field, we investigate the effectiveness of autonomous agents in a realistic network defence scenario. We first outline the problem, provide the background on reinforcement learning and detail our proposed agent design. Using a network environment simulation, with 13 hosts spanning 3 subnets, we train a novel reinforcement learning agent and show that it can reliably defend continual attacks by two advanced persistent threat (APT) red agents: one with complete knowledge of the network layout and another which must discover resources through exploration but is more general.
Hard sphere crystallization gets rarer with increasing dimension

description: We recently found that crystallization of monodisperse hard spheres from the bulk fluid faces a much higher free energy barrier in four than in three dimensions at equivalent supersaturation, due to the increased geometrical frustration between the simplex-based fluid order and the crystal [J.A. van Meel, D. Frenkel, and P. Charbonneau, Phys. Rev. E 79, 030201(R) (2009)]. Here, we analyze the microscopic contributions to the fluid-crystal interfacial free energy to understand how the barrier to crystallization changes with dimension. We find the barrier to grow with dimension and we identify the role of polydispersity in preventing crystal formation. The increased fluid stability allows us to study the jamming behavior in four, five, and six dimensions and compare our observations with two recent theories [C. Song, P. Wang, and H. A. Makse, Nature 453, 629 (2008); G. Parisi and F. Zamponi, Rev. Mod. Phys, in press (2009)].

description: We present thermodynamics of the quantum su(1,1) Landau-Lifshitz model, following our earlier exposition [J. Math. Phys. 50, 103518 (2009)] of the quantum integrability of the theory, which is based on construction of self-adjoint extensions, leading to a regularized quantum Hamiltonian for an arbitrary n-particle sector. Starting from general discontinuity properties of the functions used to construct the self-adjoint extensions, we derive the thermodynamic Bethe Ansatz equations. We show that due to non-symmetric and singular kernel, the self-consistency implies that only negative chemical potential values are allowed, which leads to the conclusion that, unlike its su(2) counterpart, the su(1,1) LL theory at T=0 has no instabilities.

By covering a frequency range of more than 15 decades, we have access to the entire variety of dynamic processes typical for glassy dynamics. These results add three more molecular glass formers to the sparse list of materials for which real broadband spectra, including the region of the fast beta-process, are available. Some first analyses of the various observed dynamic processes are provided.

description: In this paper we present the equations of motion of a moving screw dislocation in the framework of the translation gauge theory of dislocations. In the gauge field theoretical formulation, a dislocation is a massive gauge field. We calculate the gauge field theoretical solutions of a uniformly moving screw dislocation. We give the subsonic and supersonic solutions. Thus, supersonic dislocations are not forbidden from the field theoretical point of view. We show that the elastic divergences at the dislocation core are removed. We also discuss the Mach cones produced by supersonic screw dislocations.

description: In this paper we briefly review the main results obtained in arXiv:0812.1982, where some algebraic properties of the 'vector supersymmetry' (VSUSY) algebra have been studied. VSUSY is a graded extension of the Poincare' algebra in 4 dimensions with two central charges. We derive all independent Casimir operators of VSUSY and we find two distinct spin-related operators in the case of nonvanishing central charges. One is the analogue of superspin for VSUSY and the other is a new spin, called C-spin, whose value is fixed to 1/2. We also show that the VSUSY algebra and its Casimir operators can be derived by an Inonu-Wigner contraction from OSp(3,2|2). This paper is based on the talk given in Varna, Bulgaria, during the 4-th EU RTN Workshop 2008.

description: We consider the electrostatic field of a point charge coupled to Horava-Lifshitz gravity and find an exact solution describing the space with a surplus (or deficit) solid angle. Although, theoretically in general relativity, a surplus angle is hardly to be obtained in the presence of ordinary matter with positive energy distribution, it seems natural in Horava-Lifshitz gravity. We present the sudden disappearance and reappearance of a star image as an astrophysical effect of a surplus angle. We also consider matter configurations of all possible power law behaviors coupled to Horava-Lifshitz gravity and obtain a series of exact solutions.

description: We present novel evidence for the influence of malaria exposure on the geographic location of Chinese economic activities in Africa. The hypothesis is based on the observation that many Chinese aid projects and infrastructure contractors rely on Chinese personnel. High malaria exposure might constitute an important impediment to their employment and productivity. Combining data on Chinese aid and construction projects with geo-localized information about the presence of individuals from internet posts reveals a lower density of Chinese activities and of Chinese workers in areas with a high malaria exposure. This effect is mitigated partly through heterogeneity across sectors and immunity of the local population, through the selection of Chinese workers from regions in China with historically high malaria risk, and through the availability of malaria treatment

description: Este é um artigo oriundo da pesquisa de mestrado desenvolvida no Programa de Pós-Graduação em Estudos em Linguagens (POSLING) do CEFET-MG. Na pesquisa, foi apresentada uma prática experimental em tradução realizada a partir do poema On the Grasshopper and Cricket do poeta romântico John Keats. Para este artigo, o tema será abordado a partir de um diálogo com a “crise de verso” preconizada por Mallarmé, que abriu caminho para as reflexões concretistas sobre a linguagem poética. Reconhecida essa crise, portanto, tem-se o intuito de levantar a discussão sobre sua potencialidade para uma proposta de tradução que se atente para a visualidade do poema e a relação que pode ser estabelecida com seu suporte espacial em uma tradução que lance suas bases para além do verbal. Ao pensar a tradução considerando aspectos visuais do poema, a pesquisa traz, ainda, apontamentos sobre as possíveis associações entre tradução, visualidade poética e produção editorial.

description: Traditional communication theory assumes that all communicators are people and all machines are tools. However, artificial intelligence (AI) challenges traditional communication theory now that machines automate decision-making and author information independent of human coders. Human-machine communication (HMC) represents a radical departure from traditional comm theory by recognizing that machines are legitimate communicators that we communicate with, not just thru (Guzman, 2018). In this study, I use Amazon Go cashierless convenience store as a case of HMC to explore the imagined affordances of sensor fusion techniques. Marketed as “the future of shopping” Amazon Go is the first smart retail environment to deploy sensor fusion AI techniques. Here’s how the stores work: Customers download the Amazon Go mobile app and scan their unique QR code upon entering the store. Like scanning a commuter pass at a subway station, the mobile app functions as a digital passport that opens a turnstile and as a method of payment, thereby collapsing the space between access and the ability to pay. Instead of waiting in a checkout queue or scanning items, shoppers just walk out. Within the context of Amazon Go, shoppers’ mobile smartphone devices, weighted shelves, and computer vision cameras infer what shoppers buy through human action recognition (HAR). In this case study, I adapt and expand on existing methods to overcome the challenges of traditional communication theory. Using (1) semi-structured interviews, (2) the walkthrough method (Light, Burgess & Duguay, 2018), and (3) an ethnographic smart infrastructure walkthrough, I explore the imagined affordances of cashierless environments using three key constructs–affect, materiality, and mediation–to guide my research questions: 1. How are material affordances of commercial smart environments imagined among stakeholders? 2. How are the affective signatures of commercial smart environments imagined among stakeholders? 3. How are the mediated affordances of commercial smart environments imagined among stakeholders?

description: Human beings keep exploring the physical space using information means. Only recently, with the rapid development of information technologies and the increasing accumulation of data, human beings can learn more about the unknown world with data-driven methods. Given data timeliness, there is a growing awareness of the importance of real-time data. There are two categories of technologies accounting for data processing: batching big data and streaming processing, which have not been integrated well. Thus, we propose an innovative incremental processing technology named after Stream Cube to process both big data and stream data. Also, we implement a real-time intelligent data processing system, which is based on real-time acquisition, real-time processing, real-time analysis, and real-time decision-making. The real-time intelligent data processing technology system is equipped with a batching big data platform, data analysis tools, and machine learning models. Based on our applications and analysis, the real-time intelligent data processing system is a crucial solution to the problems of the national society and economy.

description: On the basis of the C-metric, we investigate the conformal Schwarzschild - deSitter spacetime and compute the source stress tensor and study its properties, including the energy conditions. Then we study its extremal version ($b^{2} = 27m^{2}$, where $b$ is the deS radius and $m$ is the source mass), when the metric is nonstatic. The weak-field version is analyzed in several frames, and the metric becomes flat with the special choice $b = 1/a$, $a$ being the constant acceleration of the Schwarzschild-like mass or black hole. This form is Rindler's geometry in disguise and is also conformal to a de Sitter metric where the acceleration plays the role of the Hubble constant. In its time dependent version, one finds that the proper acceleration of a static observer is constant everywhere, in contrast with the standard Rindler case. The timelike geodesics along the z-direction are calculated and proves to be hyperbolae.

description: In this article, a simple methodology to predict the total fertility rate of Afghanistan via a Bayesian statistical analysis method has been applied. Rstatistical analysis tool is used for data analysis. To forecast, the ”bayesforecast” package is needed. It is a substitute package in R for the ”forecast” package in the traditional (frequentest) statistical method. The Bayesian data analysis using the specific case of the general auto-regressive integrated moving average model (ARIMA) is processed as follows; As the first step, the stationarity of the given data-set is assessed, the time series has been made stationary by taking differences. After fitting several models, as the most appropriate fitted model, the ARIMA (1, 2, 1) model has been fitted to the data. The accuracy of the fitted model is examined, and thereafter, the developed model is analyzed. The posterior computation is done, using the Markov Chain Monte Carlo (MCMC) simulation method. The method ultimately focuses on drawing relevant inferences including the 16 years prediction, and the results are; in general, found to be satisfactory.

description: In a typical customer service chat scenario, customers contact a support center to ask for help or raise complaints, and human agents try to solve the issues. In most cases, at the end of the conversation, agents are asked to write a short summary emphasizing the problem and the proposed solution, usually for the benefit of other agents that may have to deal with the same customer or issue. The goal of the present article is advancing the automation of this task. We introduce the first large scale, high quality, customer care dialog summarization dataset with close to 6500 human annotated summaries. The data is based on real-world customer support dialogs and includes both extractive and abstractive summaries. We also introduce a new unsupervised, extractive summarization method specific to dialogs.

description: Using the convex-roof extended negativity and the negativity of assistance as quantifications of bipartite entanglement, we consider the possible remotely-distributed entanglement. For two pure states $\ketϕ_{AB}$ and $\ketψ_{CD}$ on bipartite systems $AB$ and $CD$, we first show that the possible amount of entanglement remotely distributed on the system $AC$ by joint measurement on the system $BD$ is not less than the product of two amounts of entanglement for the states $\ketϕ_{AB}$ and $\ketψ_{CD}$ in two-qubit and two-qutrit systems. We also provide some sufficient conditions, for which the result can be generalized into higher-dimensional quantum systems.

description: In the past, the isolated, radio-quiet neutron star RX J0720.4-3125 showed variations in the spectral parameters (apparent radius, temperature of the emitting area and equivalent width of the absorption feature) seen in the X-ray spectra, not only during the spin period of 8.39s, but also over time scales of years. New X-ray observations of RX J0720.4-3125 with XMM Newton extend the coverage to about 7.5 years with the latest pointing performed in November 2007. Out of a total of fourteen available EPIC-pn datasets, eleven have been obtained with an identical instrumental setup (full frame read-out mode with thin filter), and are best suited for a comparative investigations of the spectral and timing properties of this enigmatic X-ray pulsar. We analysed the new XMM Newton observations together with archival data in order to follow the spectral and temporal evolution of RX J0720.4-3125 All XMM-Newton data were reduced with the standard XMM-SAS software package. A systematic and consistent data reduction of all these observations was emphasised in order to reduce systematic errors as far as possible. We investigate the phase residuals derived from data from different energy bands using different timing solutions for the spin period evolution and confirm the phase lag between hard and soft photons. The phase shift in the X-ray pulses between hard and soft photons varies with time and changes sign around MJD=52800 days, regardless of the chosen timing solution. The phase residuals[abridge]

description: In this paper, a quantitative research survey is carried out on discrete-time queueing models. In real-life scenarios, the idea of discrete-time queues has taken on a new meaning. This survey mainly focuses on the unfolding of discrete-time queueing models in recent decades, challenges implied on them and their influence in various fields. The ultimate goal of this paper is to provide enough information to all the researchers and analysts who toil in this field and wish to know more about these models. A few open issues and intriguing future research paths has been discussed.

description: A hidden symmetry of the nonlinear wave equation is exploited to analyse the propagation of paraxial and uniform atom-laser beams in time-independent, quadratic and cylindrical potentials varying smoothly along the propagation axis. The quality factor and the paraxial ABCD formalism are generalized to account exactly for mean-field interaction effects in such beams. Using an approach based on moments, these theoretical tools provide a very simple and yet exact picture of the interacting beam profile evolution. Guided atom laser experiments are discussed. This treatment addresses simultaneously optical and atomic beams in a unified manner, exploiting the formal analogy between nonlinear optics and nonlinear paraxial atom optics.

A FUZZY INNOVATIVE ORDERING PLAN USING STOCK DEPENDENT HOLDING COST OF INSPECTION WITH SHORTAGES IN TIME RELIABILITY DEMAND USING TFN

Triangular Fuzzy Numbers
Stock depending holding cost
Varying order Cost

description: The considerations in this paper are, the demand is consistent with time deterioration, the holding cost is dependent based on the quantity of stock available in the system, and the ordering cost is linear and time-dependent. This system should be considered in terms of fuzziness. It is assumed that the shortages are permitted partially, the order is inspected, defective items are identified, by using penalty cost, the defective items should be minimized. Under the classical model and fuzzy environment, the mathematical equation is arrived at to find the optimal solution of total relevant cost with optimal order quantity and time using triangular fuzzy numbers. Defuzzification has been accomplished through the use of the signed distance method of integration. The solutions have been arrived and the model numerical problem of three levels of values (lower, medium and upper) in parametric changes has been verified. Using Sensitivity analysis, the solution is used to validate the changes in different parameter values of the system. To demonstrate the convexity of the TRC function over time, it has used a three-dimensional mesh graph.

description: The analysis of an M/M/1/N feedback working vacation queueing system with reneging is presented in this paper. Customers may become impatient and even disappointed when they see a long line. In the literature on queueing, customer dissatisfaction caused on by unsatisfactory service is referred as feedback. In the case of feedback, customers retry services after receiving unsatisfactory or incomplete. First, we create the equations for the steady-state probabilities using the Markov process method. The steady-state probabilities are then solved by the matrix method. We then provide some system performance measures. We create a cost model using performance analysis. Finally, we give some numerical examples to show how the various model parameters affect the system’s behaviour.
Guidelines on how to include the gender perspective in the analysis of migration narratives

description: This document is aimed at providing theoretical and methodological guidelines on how to include the gender perspective in the analysis of migration narratives in the BRIDGES project. The theoretical part is inspired by some key questions related to the effects of migration on gender relations, the impact of gender on the representation of migration and to how the media and political spheres shape migration narratives from a gender perspective. This section entails both conceptual reflections and empirical studies undertaken in different parts of Europe. The methodological part is based on indications of how to include the gender perspective throughout the project, from data-gathering and analysis to co-production and dissemination activities. This includes sampling criteria and sources of data on the one hand, and a series of dimensions, indicators, and key questions linked to the different Work Packages, on the other. In sum, these guidelines are to make sure that the project remains gender-sensitive throughout its life-course and they may also inspire other projects dealing with narratives or migration issues with a gender and intersectional perspective.

Two-Commodity

description: In this work, a single server implements a two-commodity inventory queueing system. We assume that both commodities have a finite capacity. Customers arrive by a Markovian Arrival Process, there is a need for a single item, and either or both types of commodities are required, and this requirement is modeled using certain probabilities. The lead times are exponentially distributed, and the service times have a PH distribution. We use matrix analytical techniques to investigate the queueing inventory system and adopt an (s, S)-type replenishment policy that is dependent on the type of commodity. In the steady state, the joint and individual probability distribution of the Esystem, inventory level, and server status is obtained. A few significant performance measures are attained. Our mathematical concept is then illustrated with a few numerical examples.
Twist-three at five loops, Bethe Ansatz and wrapping

description: We present a formula for the five-loop anomalous dimension of N=4 SYM twist-three operators in the sl(2) sector. We obtain its asymptotic part from the Bethe Ansatz and finite volume corrections from the generalized Luescher formalism, considering scattering processes of spin chain magnons with virtual particles that travel along the cylinder. The complete result respects the expected large spin scaling properties and passes non-trivial tests including reciprocity constraints. We analyze the pole structure and find agreement with a conjectured resummation formula. In analogy with the twist-two anomalous dimension at four-loops, wrapping effects are of order log^2 M/M^2 for large values of the spin.

Delay time

description: The arrival of high priority customers is governed by the Poisson process while that of low priority customers is governed by the Markovian Arrival Process, and the service times are determined by a distinct Phase-type distribution. When the service is finished and the system is empty, the server stays idle for a random period (delay time). If a customer arrives within the delayed period, the server resumes normal service to the customer immediately. Otherwise, at the end of the delayed period, the server will take a working vacation and will instantly provide slow service to customers (high priority customers only). The Matrix analytic method is used to investigate the system. We also discussed the steady-state vector and busy period for our concept. The estimated and visually displayed performance measures of the system.
Fermionic multi-scale entanglement renormalization ansatz

description: In a recent contribution [arXiv:0904:4151] entanglement renormalization was generalized to fermionic lattice systems in two spatial dimensions. Entanglement renormalization is a real-space coarse-graining transformation for lattice systems that produces a variational ansatz, the multi-scale entanglement renormalization ansatz (MERA), for the ground states of local Hamiltonians. In this paper we describe in detail the fermionic version of the MERA formalism and algorithm. Starting from the bosonic MERA, which can be regarded both as a quantum circuit or in relation to a coarse-graining transformation, we indicate how the scheme needs to be modified to simulate fermions. To confirm the validity of the approach, we present benchmark results for free and interacting fermions on a square lattice with sizes between $6 \times 6$ and $162\times 162$ and with periodic boundary conditions. The present formulation of the approach applies to generic tensor network algorithms.

description: This manuscript focuses on the statistical properties and estimation methods of the exponentiated Suja distribution, which is characterized by two parameters: scale and shape. From a frequentist perspective, our primary emphasis is on estimation techniques. Additionally, we derive statistical and reliability characteristics for the model. We explore various estimation procedures, including order statistics, entropies, reliability analysis, and the maximum likelihood method. To assess the model's superiority and practical utility, we analyze real lifetime data sets. Overall, this study provides a comprehensive analysis of the exponentiated Suja distribution, offering insights into its statistical properties, estimation techniques, and real-life applications.
