description: The Central Limit Theorem (CLT) is one of the most fundamental results in statistics. It states that the standardized sample mean of a sequence of $n$ mutually independent and identically distributed random variables with finite first and second moments converges in distribution to a standard Gaussian as $n$ goes to infinity. In particular, pairwise independence of the sequence is generally not sufficient for the theorem to hold. We construct explicitly a sequence of pairwise independent random variables having a common but arbitrary marginal distribution $F$ (satisfying very mild conditions) for which the CLT is not verified. We study the extent of this 'failure' of the CLT by obtaining, in closed form, the asymptotic distribution of the sample mean of our sequence. This is illustrated through several theoretical examples, for which we provide associated computing codes in the R language.

description: Understanding the physical and evolutionary properties of Hot Stellar Systems (HSS) is a major challenge in astronomy. We studied the dataset on 13456 HSS of Misgeld and Hilker (2011) that includes 12763 candidate globular clusters using stellar mass ($M_s$), effective radius ($R_e$) and mass-to-luminosity ratio ($M_s/L_ν$), and found multi-layered homogeneous grouping among these stellar systems. Our methods elicited eight homogeneous ellipsoidal groups at the finest sub-group level. Some of these groups have high overlap and were merged through a multi-phased syncytial algorithm motivated from Almodóvar-Rivera and Maitra (2020). Five groups were merged in the first phase, resulting in three complex-structured groups. Our algorithm determined further complex structure and permitted another merging phase, revealing two complex-structured groups at the highest level. A nonparametric bootstrap procedure was also used to estimate the confidence of each of our group assignments. These assignments generally had high confidence in classification, indicating great degree of certainty of the HSS assignments into our complex-structured groups. The physical and kinematic properties of the two groups were assessed in terms of $M_s$, $R_e$, surface density and $M_s/L_ν$. The first group consisted of older, smaller and less bright HSS while the second group consisted of brighter and younger HSS. Our analysis provides novel insight into the physical and evolutionary properties of HSS and also helps understand physical and evolutionary properties of candidate globular clusters. Further, the candidate globular clusters (GCs) are seen to have very high chance of really being GCs rather than dwarfs or dwarf ellipticals that are also indicated to be quite distinct from each other.

description: In this paper, we establish various maximum principles and develop the method of moving planes and the sliding method (on general unbounded domains) for equations involving the uniformly elliptic nonlocal Bellman operator. As a consequence, we derive multiple applications of these maximum principles and the moving planes method. For instance, we prove symmetry, monotonicity and uniqueness results and asymptotic properties for solutions to various equations involving the uniformly elliptic nonlocal Bellman operator in bounded domains, unbounded domains, epigraph or $\mathbb{R}^{n}$. In particular, the uniformly elliptic nonlocal Monge-Ampère operator introduced by Caffarelli and Charro in \cite{CC} is a typical example of the uniformly elliptic nonlocal Bellman operator.

description: Given a subgroup H of a finite group G, we begin a systematic study of the partial representations of G that restrict to global representations of H. After adapting several results from [DEP00] (which correspond to the case where H is trivial), we develop further an effective theory that allows explicit computations. As a case study, we apply our theory to the symmetric group and its subgroup of permutations fixing 1: this provides a natural extension of the classical representation theory of the symmetric group.

description: This policy brief is aimed at everyone interested and engaged in or affected by efforts to measure irregular migration and provides an up-to-date outline of ethical dimensions to be considered for such an endeavour.
Irregular migrants generally are considered as a particular vulnerable group. Therefore, it is imperative to consider the ethical dimensions of addressing irregular migration, including efforts to quantify this phenomenon. These considerations need to be grounded in the values of Responsible & Innovation (RRI) framework and Research Integrity, legal data protection regulations, and specifications outlined in sector-specific Codes of Ethical Conduct. This policy brief uses the term ethical standards to comprise ethical requirements. In the last decade, the understanding of what is deemed to be ethically required has evolved substantially due to updating of regulatory frameworks, the advancements of digital technologies and enhancements of ethical sensitivity. Against this background, the policy brief introduces the current regulatory frameworks consisting of legal data protection regulations and domain-specific codes of ethical conduct that stipulate the scope of what is legally permitted and ethically required. The digitisation of the social world has generated an ubiquity of smart-technologies that capture information of incidents, sequences and individuals. Yet, the emergence of machine-learning and artificial intelligence creates new and unforeseen risks, such as the violation of legal regulations and standards of ethical conduct. Finally, the intensive and ongoing efforts to develop measures and tools that support and secure compliance with ethical standards require formation and further finetuning of context-sensitive ethical toolkits that can account for the different contextual particularities. In a nutshell, the current determination of ethical standards displays features of volatility thus demanding a continuous updating.

description: People with Parkinson's disease must be regularly monitored by their physician to observe how the disease is progressing and potentially adjust treatment plans to mitigate the symptoms. Monitoring the progression of the disease through a voice recording captured by the patient at their own home can make the process faster and less stressful. Using a dataset of voice recordings of 42 people with early-stage Parkinson's disease over a time span of 6 months, we applied multiple machine learning techniques to find a correlation between the voice recording and the patient's motor UPDRS score. We approached this problem using a multitude of both regression and classification techniques. Much of this paper is dedicated to mapping the voice data to motor UPDRS scores using regression techniques in order to obtain a more precise value for unknown instances. Through this comparative study of variant machine learning methods, we realized some old machine learning methods like trees outperform cutting edge deep learning models on numerous tabular datasets.

description: This study analyzes the usage of Japanese gendered language on Twitter. Starting from a collection of 408 million Japanese tweets from 2015 till 2019 and an additional sample of 2355 manually classified Twitter accounts timelines into gender and categories (politicians, musicians, etc). A large scale textual analysis is performed on this corpus to identify and examine sentence-final particles (SFPs) and first-person pronouns appearing in the texts. It turns out that gendered language is in fact used also on Twitter, in about 6% of the tweets, and that the prescriptive classification into "male" and "female" language does not always meet the expectations, with remarkable exceptions. Further, SFPs and pronouns show increasing or decreasing trends, indicating an evolution of the language used on Twitter.

description: A novel multi-task Gaussian process (GP) framework is proposed, by using a common mean process for sharing information across tasks. In particular, we investigate the problem of time series forecasting, with the objective to improve multiple-step-ahead predictions. The common mean process is defined as a GP for which the hyper-posterior distribution is tractable. Therefore an EM algorithm is derived for handling both hyper-parameters optimisation and hyper-posterior computation. Unlike previous approaches in the literature, the model fully accounts for uncertainty and can handle irregular grids of observations while maintaining explicit formulations, by modelling the mean process in a unified GP framework. Predictive analytical equations are provided, integrating information shared across tasks through a relevant prior mean. This approach greatly improves the predictive performances, even far from observations, and may reduce significantly the computational complexity compared to traditional multi-task GP models. Our overall algorithm is called \textsc{Magma} (standing for Multi tAsk Gaussian processes with common MeAn). The quality of the mean process estimation, predictive performances, and comparisons to alternatives are assessed in various simulated scenarios and on real datasets.

A stabilized GMRES method for singular and severely ill-conditioned systems of linear equations

description: Consider using the right-preconditioned GMRES (AB-GMRES) for obtaining the minimum-norm solution of inconsistent underdetermined systems of linear equations. Morikuni (Ph.D. thesis, 2013) showed that for some inconsistent and ill-conditioned problems, the iterates may diverge. This is mainly because the Hessenberg matrix in the GMRES method becomes very ill-conditioned so that the backward substitution of the resulting triangular system becomes numerically unstable. We propose a stabilized GMRES based on solving the normal equations corresponding to the above triangular system using the standard Cholesky decomposition. This has the effect of shifting upwards the tiny singular values of the Hessenberg matrix which lead to an inaccurate solution. We analyze why the method works. Numerical experiments show that the proposed method is robust and efficient, not only for applying AB-GMRES to underdetermined systems, but also for applying GMRES to severely ill-conditioned range-symmetric systems of linear equations.

Electrification of Rural Health Centers in Rwanda Using Energy Access Explorer
Creators: name: BARORUKIZE, Jean Baptiste
Publisher: name: Zenodo

description: The report prioritizes the electrification of rural health centres in Rwanda using the Energy Access Explorer (EAE) platform to guide electrification planning. With datasets selected in EAE, Population, distribution lines, global horizontal irradiation, Relative wealth Index and accessibility to cities; the results show two scenarios, areas far away from existing distribution line,>2km, these areas can be electrified using off-Grid solutions, i.e solar. Hence the health centers located in these areas can benefit from this source of energy by getting electricity. The second scenario are the areas that are near the distribution lines, at the distance less than 2 km from the grid, these areas can get electricity from the grid by its expansion and are said to be Grid connected. The health centers that are in these areas can get electricity for the grid. The report shows that in Rwanda on Grid and Off grid connection is possible and this is not different from the reality as the utility report shows the use of these two sources of electricity. The Government of Rwanda should continue to use both off grid and on grid solutions as source of electricity; this can be cost effective in electrification projects.

description: For an unknown linear system, starting from noisy open-loop input-state data collected during a finite-length experiment, we directly design a linear feedback controller that guarantees robust invariance of a given polyhedral set of the state in the presence of disturbances. The main result is a necessary and sufficient condition for the existence of such a controller, and amounts to the solution of a linear program. The benefits of large and rich data sets for the solution of the problem are discussed. A numerical example about a simplified platoon of two vehicles illustrates the method.

description: Tidal wetlands such as mangroves and salt marshes possess many valuable attributes, ranging from forest and fishery products to ecosystem services such as shoreline protection and water filtration. In many parts of the world, past impacts and current pressures threaten the viability of these areas. There is wide interest in mangrove restoration, with increasing focus on the functional aspects of rehabilitated systems. Achieving these goals requires attention to restoring linkages, such as those between mangroves and adjacent salt -tolerant vegetation types, including salt marshes.

description: On the basis of an initial interest in symmetric cryptography, in the present work we study a chain of subgroups. Starting from a Sylow $2$-subgroup of AGL(2,n), each term of the chain is defined as the normalizer of the previous one in the symmetric group on $2^n$ letters. Partial results and computational experiments lead us to conjecture that, for large values of $n$, the index of a normalizer in the consecutive one does not depend on $n$. Indeed, there is a strong evidence that the sequence of the logarithms of such indices is the one of the partial sums of the numbers of partitions into at least two distinct parts.
THE GREEN SYNTHESIS AND MATERIAL AND ORGANIC APPLICATIONS OF BORANE-AMINES

description: Reported herein is a brief summary regarding the previous syntheses of borane-amines, newly developed protocols to synthesize borane-amines, and the material and synthetic applications utilizing borane-amines. Methods to generate borane-amines typically relied on a metathesis-dehydrogenation reaction between ammonium salts and metal borohydrides in organic solvent, typically hazardous tetrahydrofuran (THF). However, due to the poor solubility of inorganic salts in organic solvent, stirring of the reaction mixture becomes difficult and, in turn, scalability is made challenging. We report two new methods to generate borane-amines that both rely on the hydroboration of sodium borohydride and a carbonyl activator, followed by the SN2-type reaction with the amine to form the requisite borane-amine. The activator for our procedures are either 1) gaseous carbon dioxide or 2) water/ethyl acetate system. The CO2 mediated protocol was applied to a variety of 1°-, 2°-, 3°-, and heteroaromatic amines as well as phosphines to form the corresponding borane adducts (73-99%). Water was also found to be a green, compatible activator. Interestingly, we had swapped environmentally and health hazardous THF with ethyl acetate (EtOAc) and found the reaction had still proceeded with competitive conversion of amines to the borane-amines (72-97%). The robustness of this reaction was demonstrated with a 1.1 mol scale synthesis of borane pyridine with 87% yield. With increased accessibility of borane-amines established, we sought to investigate their potential applications, including testing their hypergolic properties. Additionally, we utilized borane-ammonia for a sequential reduction/Friedel-Crafts alkylation of benzyl carbonyls. Traditionally an alkyl halide, the scope of the electrophilic aromatic substitution reaction has widened to include alcohols and carbonyls as potential Friedel-Crafts reactants. Few reports exist for the arylation of aldehydes and ketones, while no precedence exists for the arylation of carboxylic acids and esters. Our group previously reported that TiCl4 is capable of eliminating oxygen from benzyl alcohols, forming a carbocation intermediate. Theoretically, the carbocation formed from TiCl4 and benzyl alcohols would be vulnerable from attacks from other nucleophiles, including pi bonds from arenes. This was indeed proven to be the case when benzyl alcohol was reacted in 1 equiv. TiCl4 with benzene as the solvent and diphenylmethane was obtained as the sole product. By including borane-ammonia as a hydride source, various aryl carbonyls and aryl carbinols were also reduced to the corresponding alcohol in situ, enabling these substrates to participate in Friedel-Crafts alkylation.

description: We extend the work of Contaldi et al. and derive analytical approximations for primordial power spectra arising from models of inflation which include primordial spatial curvature. These analytical templates are independent of any specific inflationary potential and therefore illustrate and provide insight into the generic effects and predictions of primordial curvature, manifesting as cut-offs and oscillations at low multipoles and agreeing with numerical calculations. We identify through our analytical approximation that the effects of curvature can be mathematically attributed to shifts in the wavevectors participating dynamically.

description: Spontaneous symmetry breaking constitutes a paradigmatic classification scheme of matter. However, broken symmetry also entails domain degeneracy that often impedes identification of novel low symmetry states. In quantum matter, this is additionally complicated by competing intertwined symmetry breaking orders. A prime example is that of unconventional superconductivity and density-wave orders in doped cuprates in which their respective symmetry relation remains a key question. Using uniaxial pressure as a domain-selective stimulus in combination with x-ray diffraction, we unambiguously reveal that the fundamental symmetry of the charge order in the prototypical cuprate La$_{1.88}$Sr$_{0.12}$CuO$_4$ is characterized by uniaxial stripes. We further demonstrate the direct competition of this stripe order with unconventional superconductivity via magnetic field tuning. The stripy nature of the charge-density-wave state established by our study is a prerequisite for the existence of a superconducting pair-density-wave -- a theoretical proposal that clarifies the interrelation of intertwined quantum phases in unconventional superconductors -- and paves the way for its high-temperature realization.

description: Andersen's tale The Shadow offers a theatrical situation confronting a Scholar to his Shadow. I program specific creatures that I called shadow avatar to stage the story with five of them and a physical narrator. Echoing Edmond Couchot's ideas about virtual people helping human beings to adapt to technological evolutions, I describe dynamics of coevolution characterizing the relationship between a director, actors, and shadow avatars during the process of staging The Shadow.

description: The novel notion of rigid commutators is introduced to determine the sequence of the logarithms of the indices of a certain normalizer chain in the Sylow 2-subgroup of the symmetric group on 2^n letters. The terms of this sequence are proved to be those of the partial sums of the partitions of an integer into at least two distinct parts, that relates to a famous Euler's partition theorem.

description: Background. Neonatal immune system is not fully developed at birth; newborns have an adequate leukocytes and lymphocytes count at birth but these cells lack of function.
Objective. To assess the functional activity of T-cells at birth and at 30 days of life and the influence of the main perinatal factors in a population of preterm infants.
Design. A prospective longitudinal study was carried out in a population of 59 preterms. Fifteen healthy adults were included as a control group. Blood samples were collected at birth and at 30 days of life to evaluate CD4+ T cell activity using the Immuknow® assay. 
Results. CD4+ T cell activity at birth and at 30 days of life were significantly lower compared with adult controls (p < .001). Twins showed lower activity compared to singletons (p= .005). Infants born to vaginal delivery had higher CD4+ T cell activity compared to those born to c-section (p=0.031); infants born after pPROM  showed a higher activity at birth (p= .002). Low levels of CD4+ T cells activation at birth were associated with necrotizing enterocolitis development in the first week of life (p=.049).
Conclusions. Preterm infants show a lack in CD4+ T cells activation at birth. Perinatal factors such as intrauterine inflammation, mode of delivery, zygosity can influence the levels of adaptative immune activity at birth and can contribute to expose these infants to serious complications such as NEC.

description: A wide range of geophysical methods is used for the exploration of deep geothermal resources. It aimsat characterizing the deep fractured network and its capacity for fluid/heat extraction. This relieshowever on the capacity of geophysical techniques to 1) image the geometry of the fractured networkbut also 2) characterize the petro-physical properties of the fracture network and matrix. The challengeis however that the geophysical inverse problem is ill-posed and multi-scale.To overcome these challenges, we propose here to take a multi-physics and multi-scale approach of thegeophysical/petro-physical inverse problem. To do so, we are developing iteratively petro-physical andgeophysical models that can explain the observables at the different scales. In this paper, we report outthe results of the first iteration phase of this research project that consists in building an initial petrophysical model from well logs and prior geological knowledge, and single-domain inversion ofgeophysical data. We applied this methodology to the Upper Rhine Graben where a wealth ofknowledge and dataset on deep fractured formations are available.

hr-adaptivity for nonconforming high-order meshes with the target matrix optimization paradigm

description: We present an $hr$-adaptivity framework for optimization of high-order meshes. This work extends the $r$-adaptivity method for mesh optimization by Dobrev et al., where we utilized the Target-Matrix Optimization Paradigm (TMOP) to minimize a functional that depends on each element's current and target geometric parameters: element aspect-ratio, size, skew, and orientation. Since fixed mesh topology limits the ability to achieve the target size and aspect-ratio at each position, in this paper we augment the $r$-adaptivity framework with nonconforming adaptive mesh refinement to further reduce the error with respect to the target geometric parameters. The proposed formulation, referred to as $hr$-adaptivity, introduces TMOP-based quality estimators to satisfy the aspect-ratio-target via anisotropic refinements and size-target via isotropic refinements in each element of the mesh. The methodology presented is purely algebraic, extends to both simplices and hexahedra/quadrilaterals of any order, and supports nonconforming isotropic and anisotropic refinements in 2D and 3D. Using a problem with a known exact solution, we demonstrate the effectiveness of $hr$-adaptivity over both $r-$ and $h$-adaptivity in obtaining similar accuracy in the solution with significantly fewer degrees of freedom. We also present several examples that show that $hr$-adaptivity can help satisfy geometric targets even when $r$-adaptivity fails to do so, due to the topology of the initial mesh.

Subsequential tightness for branching random walk in random environment

Subjects: subject: Probability (math.PR)

description: We consider branching random walk in random environment (BRWRE) and prove the existence of deterministic subsequences along which their maximum, centered at its mean, is tight. This partially answers an open question in arXiv:1711.00852. The method of proof adapts an argument developed by Dekking and Host for branching random walks with bounded increments. The question of tightness without the need for subsequences remains open.

Bulk viscosity of spin-one color superconductors with two quark flavors

description: We consider the contribution of the Urca-type processes to the bulk viscosity of several spin-one color-superconducting phases of dense two-flavor quark matter. In the so-called transverse phases which are suggested to be energetically favorable at asymptotic densities, the presence of ungapped quasiparticle modes prevents that spin-one color superconductivity has a large effect on the bulk viscosity. When all modes are gapped, as for one particular color-spin-locked phase, the effect on the viscosity can be quite large, which may have important phenomenological implications.

description: In this paper, we prove a local limit theorem for the ratio of the Poisson distribution to the Gaussian distribution with the same mean and variance, using only elementary methods (Taylor expansions and Stirling's formula). We then apply the result to derive an upper bound on the Le Cam distance between Poisson and Gaussian experiments, which gives a complete proof of the sketch provided in the unpublished set of lecture notes by Pollard (2010), who uses a different approach. We also use the local limit theorem to derive the asymptotics of the variance for Bernstein c.d.f. and density estimators with Poisson weights on the positive half-line (also called Szasz estimators). The propagation of errors in the literature due to the incorrect estimate in Lemma 2 (iv) of Leblanc (2012) is addressed in the Appendix.

Exploring the Origin of CP Violation in the Standard Model

Year: 2020
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: In this article, we present a very general but not ultimate solution of CPV problem in the standard model. Our study starts from a naturally Hermitian ${\bf M^2}\equiv M^q \cdot M^{q\dagger}$ rather than the previously assumed Hermitian $M^q$. The only assumption employed here is that the real part and imaginary part of $\bf M^2$ can be, respectively, diagonalized by a common $\bf U^q$ matrix. Such an assumption leads to a $\bf M^2$ pattern which depends on only five parameters and can be diagonalized analytically by a $\bf U^q$ matrix which depends on only two of the parameters. Two of the derived mass eigenvalues are predicted degenerate if one of the parameters $\bf C ~(C')$ in up- (down-) quark sector is zero. As the $\bf U^q$ patterns are obtained, thirty-six $V_{CKM}$ candidates are yielded and only eight of them, classified into two groups, fit empirical data within the order of $O(λ)$. One of the groups is further excluded in a numerical test, and the surviving group predicts that the degenerate pair in a quark type are the lightest and the heaviest generations rather than the lighter two generations assumed in previous researches. However, there is still one unsatisfactory prediction in this research, a quadruple equality in which four CKM elements of very different values are predicted to be equal. It indicates the $\bf M^2$ pattern studied here is still oversimplified by that employed assumption and the ultimate solution can only be obtained by diagonalizing the unsimplified $\bf M^2$ matrix containing nine parameters directly. The $V_{CKM}$ presented here is already very close to such an ultimate CPV solution.

description: We develop geometric approach to A-infinity algebras and A-infinity categories based on the notion of formal scheme in the category of graded vector spaces. Geometric approach clarifies several questions, e.g. the notion of homological unit or A-infinity structure on A-infinity functors. We discuss Hochschild complexes of A-infinity algebras from geometric point of view. The paper contains homological versions of the notions of properness and smoothness of projective varieties as well as the non-commutative version of Hodge-to-de Rham degeneration conjecture. We also discuss a generalization of Deligne's conjecture which includes both Hochschild chains and cochains. We conclude the paper with the description of an action of the PROP of singular chains of the topological PROP of 2-dimensional surfaces on the Hochschild chain complex of an A-infinity algebra with the scalar product. This action is essentially equivalent to the structure of 2-dimensional Topological Field Theory associated with a Calabi-Yau category.
