description: The half-skyrmions that appear in dense baryonic matter when skyrmions are put on crystals modify drastically hadron properties in dense medium and affect strongly the nuclear tensor forces, thereby influencing the equation of state (EoS) of dense nuclear and asymmetric nuclear matter. The matter comprised of half skyrmions has vanishing quark condensate but non-vanishing pion decay constant and could be interpreted as a hadronic dual of strong-coupled quark matter. We infer from this observation combined with certain predictions of hidden local symmetry in low-energy hadronic interactionsa a set of new scaling laws -- called "new-BR" -- for the parameters in nuclear effective field theory controlled by renormalization-group flow. They are subjected to the EoS of symmetric and asymmetric nuclear matter, and are then applied to nuclear symmetry energies and properties of compact stars. The changeover from the skyrmion matter to a half-skyrmion matter that takes place after the cross-over density $n_{1/2}$ provides a simple and natural field theoretic explanation for the change of the EoS from soft to stiff at a density above that of nuclear matter required for compact stars as massive as $\sim 2.4M_\odot$. Cross-over density in the range $1.5n_0 \lsim n_{1/2} \lsim 2.0 n_0$ has been employed, and the possible skyrmion half-skyrmion coexistence {or cross-over} near $n_{1/2}$ is discussed. The novel structure of {the tensor forces and} the EoS obtained with the new-BR scaling is relevant for neutron-rich nuclei and compact star matter and could be studied in RIB (rare isotope beam) machines.

description: This thesis deals with quadratic forms and quasilinear p-forms in positive characteristic. In this setting, there are three well-known equivalence relations -- similarity, birational equivalence, and stable birational equivalence. Inspired by an algebraic characterization of motivic equivalence of quadratic forms over fields of characteristic other than two, this thesis defines a new equivalence relation -- the Vishik equivalence. The thesis is divided into chapters based on the kind of forms treated: quasilinear p-forms (over fields of characteristic p), totally singular quadratic forms, nonsingular quadratic forms, and singular quadratic forms (all of them over fields of characteristic 2). The main goal is to compare the four above-mentioned equivalences for each of those kinds of forms. We also derive some consequences of two forms being equivalent for each of the four equivalences separately. In particular, we give a new characterization of the stable birational equivalence for quadratic forms. Moreover, we provide some new results regarding the isotropy of quasilinear p-forms over field extensions.

description: The aim of this systematic review was to identify prospectively measured ankle sprain risk factors in field-based team contact sports. Eight databases including SPORTDiscus, CINAHL Complete, MEDLINE (EBSCO), Education Source, Web of Science, Scopus, Embase, and Pubmed were searched using specific Boolean terms. A modified-CASP diagnostic test assessed the quality of the included studies. Extensive data extraction included but was not limited to injury definition, protocols for injury diagnosis and recording, and outcomes associated with ankle sprain. 4012 records were returned from the online search and 17 studies met the inclusion criteria for this review. Twelve different risk factors including anatomic alignment of the foot and ankle, joint laxity, height, mass, BMI (body mass index), age, ankle strength, hip strength, single leg landing performance (ground reaction force, pelvic internal rotation, and knee varus), and single leg reach were all found to be associated with ankle sprain incidence. Injury definitions and methods of diagnosis and recording varied across the 17 studies. This review updates the literature on prospective risk factors for ankle sprain in a specific population rather than heterogeneous cohorts previously studied. From more than 20 categories of risk factors investigated for ankle sprain association across 17 studies in field-based team contact sports, 12 variables were found to be associated with increased incidence of ankle sprain. In order to reduce the risk of ankle sprain, BMI, ankle plantar and dorsiflexion strength, hip strength, and single leg landing performance should be factored in to athlete assessment and subsequent program design. More studies utilizing standardized definitions and methods of recording and reporting are needed. Future prospective etiological studies will allow strength and conditioning coaches, physiotherapists, and physicians to apply specific training principles to reduce the risk and occurrence of ankle sprain injuries.

We present an explicit formula for computing the $v_0$-reduced divisors (representatives of the equivalence classes) associated to given tableaux, and use this formula to prove (i) evacuation of tableaux corresponds (under the bijection) to reflecting the metric graph, and (ii) conjugation of the tableaux corresponds to taking the Riemann-Roch dual of the divisor.

description: The usual Minimum Covariance Determinant (MCD) estimator of a covariance matrix is robust against casewise outliers. These are cases (that is, rows of the data matrix) that behave differently from the majority of cases, raising suspicion that they might belong to a different population. On the other hand, cellwise outliers are individual cells in the data matrix. When a row contains one or more outlying cells, the other cells in the same row still contain useful information that we wish to preserve. We propose a cellwise robust version of the MCD method, called cellMCD. Its main building blocks are observed likelihood and a penalty term on the number of flagged cellwise outliers. It possesses good breakdown properties. We construct a fast algorithm for cellMCD based on concentration steps (C-steps) that always lower the objective. The method performs well in simulations with cellwise outliers, and has high finite-sample efficiency on clean data. It is illustrated on real data with visualizations of the results.

The Critical Future of Intermediate Language Translation: The Case of Italian Language and Literature in the Arab World
Creators: name: Elmenfi, Fadil
Publisher: name: figshare
Year: 2022
Subjects: English language

description: Translation studies has recently been elevated to a prestigious and noteworthy position in literary scholarship. We can understand the place of translation in literary scholarship from a perspective that stresses the necessity of avoiding the interpretation of specific literature and language in the Arab world. Various publishers in the Arab world have taken different positions on the question of literary translation. This paper sheds light on the condition and place of translated Italian literature in the Arab world by analyzing a database of Italian literature published in Arabic and the policies of two key Arab publishing firms. It examines (a) how foreign language learning is associated with spectacle in the Arab world, and (b) how the mechanisms by which publishing firms operate impact the position of Italian literature in the Arab world. It critically gauges the translation of the Italian language and literature in Arabic higher education. This study contributes to the literature by placing emphasis on the issue that is experienced by most publishing firms besides attaining a concept associated with the intermediate translation to be regarded as a savior.

We determine the hyperplane arrangement corresponding to the faces of codimension 2 of $\mathcal P_Φ$ and analyze its relation with the facets of $\mathcal P_Φ$. For $Φ$ of type $A_n$ or $C_n$, we show that the orbits of some special subsets of abelian ideals under the action of the Weyl group parametrize a triangulation of $\mathcal P_Φ$. We show that this triangulation restricts to a triangulation of the positive root polytope $\mathcal P_Φ^+$.

description: We consider the ordinary differential equation $x^2 u'' = axu'+bu-c(u'-1)^2, x\in (0,x_0)$, with $a\in\mathbb{R}, b\in\mathbb{R}$, $c>0$ and the singular initial condition $u(0)=0$, which in financial economics describes optimal disposal of an asset in a market with liquidity effects. It is shown in the paper that if $a+b < 0$ then no solutions exist, whereas if $a+b\ge0$ then there are infinitely many solutions with indistinguishable asymptotics near 0. Moreover, it is proved that in the latter case there is precisely one solution $u$ corresponding to the choice $x_0=\infty$ which is such that $0 \le u(x)\le x$ for all $x>0$, and that this solution is strictly increasing and concave.

description: The proliferation of models for networks raises challenging problems of model selection: the data are sparse and globally dependent, and models are typically high-dimensional and have large numbers of latent variables. Together, these issues mean that the usual model-selection criteria do not work properly for networks. We illustrate these challenges, and show one way to resolve them, by considering the key network-analysis problem of dividing a graph into communities or blocks of nodes with homogeneous patterns of links to the rest of the network. The standard tool for doing this is the stochastic block model, under which the probability of a link between two nodes is a function solely of the blocks to which they belong. This imposes a homogeneous degree distribution within each block; this can be unrealistic, so degree-corrected block models add a parameter for each node, modulating its over-all degree. The choice between ordinary and degree-corrected block models matters because they make very different inferences about communities. We present the first principled and tractable approach to model selection between standard and degree-corrected block models, based on new large-graph asymptotics for the distribution of log-likelihood ratios under the stochastic block model, finding substantial departures from classical results for sparse graphs. We also develop linear-time approximations for log-likelihoods under both the stochastic block model and the degree-corrected model, using belief propagation. Applications to simulated and real networks show excellent agreement with our approximations. Our results thus both solve the practical problem of deciding on degree correction, and point to a general approach to model selection in network analysis.

description: Special economic zones (SEZs) are a popular policy tool for the promotion of economic development. However, questions remain about their economic contribution and about what aspects of SEZ policies are most relevant to investors. This article sheds light on these issues by comparing SEZs across Africa, Asia and Latin America. We find that while investment decisions by foreign companies are driven by market access, political stability and low labour costs, adequate SEZ policies facilitate the attraction of investment. A good industrial infrastructure together with a strategic location and service provision within the zones draw investment. Fiscal incentives, by contrast, have a limited influence on investment decisions.

Proper Size of the Visible Universe in FRW Metrics with Constant Spacetime Curvature

description: In this paper, we continue to examine the fundamental basis for the Friedmann-Robertson-Walker (FRW) metric and its application to cosmology, specifically addressing the question: What is the proper size of the visible universe? There are several ways of answering the question of size, though often with an incomplete understanding of how far light has actually traveled in reaching us today from the most remote sources. The difficulty usually arises from an inconsistent use of the coordinates, or an over-interpretation of the physical meaning of quantities such as the so-called proper distance R(t)=a(t)r, written in terms of the (unchanging) co-moving radius r and the universal expansion factor a(t). In this paper, we use the five non-trivial FRW metrics with constant spacetime curvature (i.e., the static FRW metrics, but excluding Minkowski) to prove that in static FRW spacetimes in which expansion began from an initial signularity, the visible universe today has a proper size equal to R_h(t_0/2), i.e., the gravitational horizon at half its current age. The exceptions are de Sitter and Lanczos, whose contents had pre-existing positions away from the origin. In so doing, we confirm earlier results showing the same phenomenon in a broad range of cosmologies, including LCDM, based on the numerical integration of null geodesic equations through an FRW metric.

description: We report the observation of a new series of Abelian and non-Abelian topological states in fractional Chern insulators (FCI). The states appear at bosonic filling nu= k/(C+1) (k, C integers) in several lattice models, in fractionally filled bands of Chern numbers C>=1 subject to on-site Hubbard interactions. We show strong evidence that the k=1 series is Abelian while the k>1 series is non-Abelian. The energy spectrum at both groundstate filling and upon the addition of quasiholes shows a low-lying manifold of states whose total degeneracy and counting matches, at the appropriate size, that of the Fractional Quantum Hall (FQH) SU(C) (color) singlet k-clustered states (including Halperin, non-Abelian spin singlet states and their generalizations). The groundstate momenta are correctly predicted by the FQH to FCI lattice folding. However, the counting of FCI states also matches that of a spinless FQH series, preventing a clear identification just from the energy spectrum. The entanglement spectrum lends support to the identification of our states as SU(C) color-singlets but offers new anomalies in the counting for C>1, possibly related to dislocations that call for the development of new counting rules of these topological states.

description: This paper investigates the presence of spatial dependence in the non-performing loans (NPLs) ratio of small Italian cooperative banks. As these financial intermediaries operate in a delimited area, the strategies they adopt to recover NPLs can produce spatial spillover effects on the ability of neighbouring banks to recover credit. Furthermore, small banks’ reliance on the relationship lending technique to select and monitor borrowers suggests a similar ability to identify underperforming borrowers, which may have a negative impact on the community in which those banks operate. Our empirical estimations provide strong evidence for both spatial and spatial–temporal variables driving impaired loans in local banks. The results indicate different effects of the spatial terms, showing a direct positive effect of the contemporaneous spatial lag variable and a negative effect of the space–time autoregressive coefficient. Whereas the former effects can be ascribed to changes in the macroeconomic cycle, the latter confirms the insight that the recovery capacities of local banks can be harmed by neighbouring banks’ credit recovery policies.

description: Maximum entropy models are increasingly being used to describe the collective activity of neural populations with measured mean neural activities and pairwise correlations, but the full space of probability distributions consistent with these constraints has not been explored. We provide upper and lower bounds on the entropy for the {\em minimum} entropy distribution over arbitrarily large collections of binary units with any fixed set of mean values and pairwise correlations. We also construct specific low-entropy distributions for several relevant cases. Surprisingly, the minimum entropy solution has entropy scaling logarithmically with system size for any set of first- and second-order statistics consistent with arbitrarily large systems. We further demonstrate that some sets of these low-order statistics can only be realized by small systems. Our results show how only small amounts of randomness are needed to mimic low-order statistical properties of highly entropic distributions, and we discuss some applications for engineered and biological information transmission systems.

description: This study explores the relationship between the clustering of betting shops and crime in England using both spatial and multilevel modelling approaches. Spatial analysis revealed significant clustering of betting shops and crime across all crime types. Results from the multilevel models revealed statistically significant relationships between the number of betting shops and all the crime categories, with the strongest relationships observed with theft and disorder offences. These relationships were observed after controlling for socio-demographic and land-use predictors of crime. To reduce the effect of betting shops on crime, efforts should focus on place management strategies.

description: We examine the role of social capital in explaining the highly unequal regional distribution of firms’ carcinogenic releases. Our model predicts that social capital, by enabling information-sharing and coordination among community members, decreases carcinogenic releases. Our analysis, based on the US county-level releases derived from around 2 million chemical-facility-level reports during the period 1998–2019 and the instrumental variables approach, confirms our prediction. However, the impact is reduced when counties rely on waste-releasing firms for economic opportunities. An important policy implication of our study is that the efficacy of initiatives to alleviate environmental injustice is likely to depend on communities’ social capital.

description: We assess the impact of regional policies on the economies of the 20 Italian regions for the period 1994–2016. We adopt a control function approach incorporating the funds’ allocation rules and ascertain the impact of various policy funds in four sectors (agriculture, industry, construction and services) through a multi-input multi-output transformation function. We find that European Structural and Investment Funds have a significant impact on various sectoral components of regional gross domestic product (GDP) per capita, with the European Regional Development Fund (ERDF) playing the strongest role. Nationally funded regional policies do not have an aggregate impact but affect the sectoral composition of GDP.

description: This article examines regional economic convergence in two federal contexts: Brazil and the European Union. Despite many differences, in the last decades these two economies have shown irregular economic growth and been facing economic inequalities, launching public policies to reduce them. We analyse the tendencies of regional convergence within these economies between 2002 and 2019, focusing on σ-convergence, absolute convergence, convergence clubs and the transitional behaviour of club members. The results show that in both cases convergence occurs, but at a slow rhythm, especially in the European Union.

description: When high-energy single-hadron production takes place inside an identified jet, there are important correlations between the fragmentation and phase-space cuts. For example, when one-hadron yields are measured in on-resonance B-factory data, a cut on the thrust event shape T is required to remove the large b-quark contribution. This leads to a dijet final state restriction for the light-quark fragmentation process. Here we complete our analysis of unpolarized fragmentation of (light) quarks and gluons to a light hadron h with energy fraction z in e+ e- -> dijet + h at the center-of-mass energy Q=10.58 GeV. In addition to the next-to-next-to-leading order resummation of logarithms of 1-T, we include the next-to-leading order (NLO) nonsingular O(1-T) contribution to the cross section, the resummation of threshold logarithms of 1-z, and the leading nonperturbative contribution to the soft function. Our results for the correlations between fragmentation and the thrust cut are presented in a way that can be directly tested against B-factory data. These correlations are also observed in Pythia, but are surprisingly smaller at NLO.

Housing wealth distribution, inequality and residential satisfaction

description: This research investigates the relationship between housing wealth and residential satisfaction. Using household panel survey data from the UK, we find that individuals’ asymmetric responses to changes in housing wealth distribution, that is, loss aversion experienced by the worse-off group, could offset the gain from an increase in housing wealth at the aggregate level. Consequently, housing wealth growth does not necessarily improve residential satisfaction for society as a whole if it leads to housing wealth inequality. Given the significant impact of housing wealth distribution on residential satisfaction, it is important to consider housing wealth inequality in making public policy decisions.
Ion beam generated surface ripples: new insight in the underlying mechanism

description: A new hydrodynamic mechanism is proposed for the ion beam induced surface patterning on solid surfaces. Unlike the standard mechanisms based on the ion beam impact generated erosion and mass redistribution at the free surface (proposed by Bradley-Harper (BH) and its extended theories), the new mechanism proposes that the ion beam induced saltation and creep processes, coupled with incompressible solid flow in amorphous layer, leads to the formation of ripple patterns at the amorphous/crystalline (a/c) interface and hence at the free surface. Ion beam stimulated solid flow inside the amorphous layer controls the wavelength, where as the amount of material transported and re-deposited at a/c interface control the amplitude of ripples. The new approach is verified by designed experiments and supported by the discrete simulation method.

description: We prove existence and regularity of metrics on a surface with boundary which maximize sigma_1 L where sigma_1 is the first nonzero Steklov eigenvalue and L the boundary length. We show that such metrics arise as the induced metrics on free boundary minimal surfaces in the unit ball B^n for some n. In the case of the annulus we prove that the unique solution to this problem is the induced metric on the critical catenoid, the unique free boundary surface of revolution in B^3. We also show that the unique solution on the Mobius band is achieved by an explicit S^1 invariant embedding in B^4 as a free boundary surface, the critical Mobius band. For oriented surfaces of genus 0 with arbitrarily many boundary components we prove the existence of maximizers which are given by minimal embeddings in B^3. We characterize the limit as the number of boundary components tends to infinity to give the asymptotically sharp upper bound of 4pi. We also prove multiplicity bounds on sigma_1 in terms of the topology, and we give a lower bound on the Morse index for the area functional for free boundary surfaces in the ball.

Flip Distance Between Triangulations of a Simple Polygon is NP-Complete

description: Let T be a triangulation of a simple polygon. A flip in T is the operation of removing one diagonal of T and adding a different one such that the resulting graph is again a triangulation. The flip distance between two triangulations is the smallest number of flips required to transform one triangulation into the other. For the special case of convex polygons, the problem of determining the shortest flip distance between two triangulations is equivalent to determining the rotation distance between two binary trees, a central problem which is still open after over 25 years of intensive study. We show that computing the flip distance between two triangulations of a simple polygon is NP-complete. This complements a recent result that shows APX-hardness of determining the flip distance between two triangulations of a planar point set.

description: Random arrangements of points in the plane, interacting only through a simple hard core exclusion, are considered. An intensity parameter controls the average density of arrangements, in analogy with the Poisson point process. It is proved that at high intensity, an infinite connected cluster of excluded volume appears with positive probability.

description: ‘Levelling up’ – a policy agenda focused on reducing regional inequalities – has become the new mantra in British politics. This paper critiques the policy programme from its emergence in 2019 to the publication of the 2022 levelling up White Paper. While it is a welcome recognition of gross regional inequality, local institutions lack capacity to deliver, there has been little genuine devolution and our analysis shows that little new funding has been committed. ‘Levelling up’ could simply become the latest in a list of politically useful but empty slogans which are used as a substitute for resources and devolution.
Three-intensity decoy state method for device independent quantum key distribution with basis dependent errors

description: We study the measurement device independent quantum key distribution (MDIQKD) in practice with limited resource, when there are only 3 different states in implementing the decoy-state method and when there are basis dependent coding errors. We present general formulas for the decoy-state method for two-pulse sources with 3 different states, which can be applied to the recently proposed MDIQKD with imperfect single-photon source such as the coherent states or the heralded states from the parametric down conversion. We point out that the existing result for secure QKD with source coding errors does not always hold. We find that very accurate source coding is not necessary. In particular, we loosen the precision of existing result by several magnitude orders for secure QKD.
description: Published version with Eq.(17) corrected. We emphasize that our major result (Eq.16) for the decoy-state part can be applied to generate a key rate very close to the ideal case of using infinite different coherent states, as was numerically demonstrated in Ref.[21].

description: We have shown in two accompanying papers that, for Einstein gravity, the graviton multi-point functions are universal in a particular kinematic region and depend only on the (generalized) Mandelstam variable s. The effects of the leading corrections to Einstein gravity were shown to be similarly universal, inducing a specific difference in the angular dependence. Here we show, relying on the gauge-gravity duality, that the stress-tensor correlation functions of conformal fluids whose gravitational dual is either Einstein gravity or its leading correction are also universal. We discuss the possible significance of these results to multi-particle correlations in heavy-ion collisions. We show that, to test our ideas, the stress-energy correlation functions have to measured rather than the standard multiplicity correlation functions. We then discuss schematically how stress-energy correlations in heavy-ion collisions can be used to test our findings. We argue that, if these correlations can be measured precisely enough, they will provide a unique way to probe the existence of a gravitational dual to the quark-gluon plasma and to determine its universality class.
