description: The epidemiology has recently witnessed great advances based on computational models. Its scope and impact are getting wider thanks to the new data sources feeding analytical frameworks and models. Besides traditional variables considered in epidemiology, large-scale social patterns can be now integrated in real time with multi-source data bridging the gap between different scales. In a hyper-connected world, models and analysis of interactions and social behaviors are key to understand and stop outbreaks. Big Data along with apps are enabling for validating and refining models with real world data at scale, as well as new applications and frameworks to map and track diseases in real time or optimize the necessary resources and interventions such as testing and vaccination strategies. Digital epidemiology is positioning as a discipline necessary to control epidemics and implement actionable protocols and policies. In this review we address the research areas configuring current digital epidemiology: transmission and propagation models and descriptions based on human networks and contact tracing, mobility analysis and spatio-temporal propagation of infectious diseases and infodemics that comprises the study of information and knowledge propagation. Digital epidemiology has the potential to create new operational mechanisms for prevention and mitigation, monitoring of the evolution of epidemics, assessing their impact and evaluating the pharmaceutical and non-pharmaceutical measures to fight the outbreaks. Epidemics have to be approached from the lens of complexity as they require systemic solutions. Opportunities and challenges to tackle epidemics more effectively and with a human-centered vision are here discussed.

Magic mass ratios of complete energy-momentum transfer in one-dimensional elastic three-body collisions

description: We consider the one-dimensional scattering of two identical blocks of mass $M$ that exchange energy and momentum via elastic collisions with an intermediary ball of mass $m=αM$. Initially, one block is incident upon the ball with the other block at rest. For $α<1$, the three objects will make multiple collisions with one another. In our analysis, we construct a Euclidean vector $\textbf{V}_n$ whose components are proportional to the velocities of the objects. Energy-momentum conservation then requires a covariant recurrence relation for $\textbf{V}_n$ that transforms like a pure rotation in three dimensions. The analytic solutions of the terminal velocities result in a remarkable prediction for values of $α$, in cases where the initial energy and momentum of the incident block are completely transferred to the scattered block. We call these values for $α$ "magic mass ratios."

The costs and benefits of uniformly valid causal inference with high-dimensional nuisance parameters

description: Important advances have recently been achieved in developing procedures yielding uniformly valid inference for a low dimensional causal parameter when high-dimensional nuisance models must be estimated. In this paper, we review the literature on uniformly valid causal inference and discuss the costs and benefits of using uniformly valid inference procedures. Naive estimation strategies based on regularisation, machine learning, or a preliminary model selection stage for the nuisance models have finite sample distributions which are badly approximated by their asymptotic distributions. To solve this serious problem, estimators which converge uniformly in distribution over a class of data generating mechanisms have been proposed in the literature. In order to obtain uniformly valid results in high-dimensional situations, sparsity conditions for the nuisance models need typically to be made, although a double robustness property holds, whereby if one of the nuisance model is more sparse, the other nuisance model is allowed to be less sparse. While uniformly valid inference is a highly desirable property, uniformly valid procedures pay a high price in terms of inflated variability. Our discussion of this dilemma is illustrated by the study of a double-selection outcome regression estimator, which we show is uniformly asymptotically unbiased, but is less variable than uniformly valid estimators in the numerical experiments conducted.
Linking QSAR-Based Drug Target Prediction with AlphaFold

description: Drug-target interactions (DTIs) refer to the interactions of chemical compounds and biological targets, proteins in our case, inside the human body. They play a crucial role in drug discovery and pharmacology, however, their experimental determination is time-consuming and limited due to funding and the difficulty of purifying proteins. Unwanted or unexpected DTIs could cause severe side effects. Therefore, the creation of in silico machine learning models with high throughput that can quickly and confidently predict whether thousands of drugs and proteins bind together and how much could be crucial for medicinal chemistry and drug development, acting as a supplement to biological experiments. Original Aims: The project aimed to gather publicly available data on known DTIs and place them into a new curated dataset. Then, using this new dataset, train multiple machine learning models using simple QSAR descriptors derived from a drug's chemical properties and a protein's sequence and 3D structural information extracted from AlphaFold to predict whether they bind together or not. Actual Achievements: A dataset of 163,080 DTIs was gathered using a variety of databases, libraries and biochemical APIs, subsets of which were used to train both our classification and regression models, evaluated using dummy models, holdout test sets and model interpretability tools. Classification models would try to predict whether a drug-protein pair would bind together or not and Regression models would try to predict the logKd value. The models were then further split into "Baseline" and "Enhanced" with the former utilising just the QSAR descriptors from drug and proteins and the latter utilising the 3D structural embeddings in addition to the QSAR descriptors. This was naturally done in order to compare the effect, positive or negative, of the created structural embeddings to a baseline. Unfortunately, our embeddings seemed to have little effect on our baseline models, which reasonably falls down to our embeddings creation process. Even though our embeddings did not have a significant impact, our high-throughput models could still be used to uncover some interesting relationships between drugs and proteins that could be later confirmed or rejected by molecular docking simulations and actual experimental trials.

description: The purpose of this article is to develop foundational techniques from logarithmic geometry in order to define a functorial tropicalization map for fine and saturated logarithmic schemes in the case of constant coefficients. Our approach crucially uses the theory of fans in the sense of K. Kato and generalizes Thuillier's retraction map onto the non-Archimedean skeleton in the toroidal case. For the convenience of the reader many examples as well as an introductory treatment of the theory of Kato fans are included.

description: If G is a countable discrete group acting linearly on a finite-dimensional vector space over any topological field, then the groups of coboundaries are closed for the product topology in all degrees, and hence the cohomology is reduced in all degrees. This is deduced from a more general automatic-closure theorem for continuous linear transformations between inverse limits of finite-dimensional vector spaces.

Physical Process First Law and the Entropy Change of Rindler Horizons

description: The physical process version of the first law can be obtained for bifurcate Killing horizons with certain assumptions. Especially, one has to restrict to the situations where the horizon evolution is quasi-stationary, under perturbations. We revisit the analysis of this assumption considering the horizon perturbations of Rindler horizon by a spherically symmetric object. We demonstrate that even if the quasi-stationary assumption holds, the change in entropy, in four space-time dimensions, diverges when considered between asymptotic cross-sections. However, these divergences do not appear in higher dimensions. We also analyze these features in the presence of a positive cosmological constant. In the process, we prescribe a recipe to establish the physical process first law in such ill-behaved scenarios.

description: We introduce a method to compute particle detector transition probability in spacetime regions of general curved spacetimes provided that the curvature is not above a maximum threshold. In particular we use this method to compare the response of two detectors, one in a spherically symmetric gravitational field and the other one in Rindler spacetime to compare the Unruh and Hawking effects: We study the vacuum response of a detector freely falling through a stationary cavity in a Schwarzschild background as compared with the response of an equivalently accelerated detector traveling through an inertial cavity in the absence of curvature. We find that as we set the cavity in further radiuses from the black hole, the thermal radiation measured by the detector approaches the quantity recorded by the detector in Rindler background showing in which way and at what scales the equivalent principle is recovered in the Hawking-Unruh effect. I.e. when the Hawking effect in a Schwarzschild background becomes equivalent to the Unruh effect in Rindler spacetime.

On a Projection Estimator of the Regression Function Derivative

subject: FOS: Mathematics

description: In this paper, we study the estimation of the derivative of a regression function in a standard univariate regression model. The estimators are defined either by derivating nonparametric least-squares estimators of the regression function or by estimating the projection of the derivative. We prove two simple risk bounds allowing to compare our estimators. More elaborate bounds under a stability assumption are then provided. Bases and spaces on which we can illustrate our assumptions and first results are both of compact or non compact type, and we discuss the rates reached by our estimators. They turn out to be optimal in the compact case. Lastly, we propose a model selection procedure and prove the associated risk bound. To consider bases with a non compact support makes the problem difficult.

description: We study the dynamics of a quantum heavy particle undergoing a repulsive interaction with a light one. The main motivation is the detailed description of the loss of coherence induced on a quantum system (in our model, the heavy particle) by the interaction with the environment (the light particle). The content of the paper is analytical and numerical. Concerning the analytical contribution, we show that an approximate description of the dynamics of the heavy particle can be carried out in two steps: first comes the interaction, then the free evolution. In particular, all effects of the interaction can be embodied in the action of a collision operator that acts on the initial state of the heavy particle. With respect to previous analytical results on the same topics, we turn our focus from the Møller wave operator to the full scattering operator, whose analysis proves to be simpler. Concerning the numerical contribution, we exploit the previous analysis to construct an efficient numerical scheme that turns the original, multiscale, two-body problem in two one-body problems which can be solved separately. This leads to a considerable gain in simulation time. We present and interpret some simulations carried out on specific one-dimensional systems by using the new scheme. Finally, we propose a new description of the mechanism of decoherence induced by scattering: decoherence is produced by an interference-free bump which arises from the initial state of the heavy particle immediately after the collision. We support such a picture by numerical evidence as well as by an approximation theorem.

description: We report a detailed three-step roadmap for the fabrication and characterization of bulk Cr tips for spin-polarized scanning tunneling microscopy. Our strategy uniquely circumvents the need for ultra-high vacuum preparation of clean surfaces or films. First, we demonstrate the role of $ex$-$situ$ electrochemical etch parameters on Cr tip apex geometry, using scanning electron micrographs of over 70 etched tips. Second, we describe the suitability of the $in$-$situ$ cleaved surface of the layered antiferromagnet La$_{1.4}$Sr$_{1.6}$Mn$_2$O$_7$ to evaluate the spin characteristics of the Cr tip, replacing the UHV-prepared test samples that have been used in prior studies. Third, we outline a statistical algorithm that can effectively delineate closely-spaced or irregular cleaved step edges, to maximize the accuracy of step height and spin-polarization measurements.

description: We revisit the constraints on the parameter space of the Minimal Supersymmetric Standard Model (MSSM), from charge and color breaking minima in the light of information on the Higgs from the LHC so far. We study the behavior of the scalar potential keeping two light sfermion fields along with the Higgs in the pMSSM framework and analyze the stability of the vacuum. We find that for lightest stop $\lesssim 1$ TeV and small $μ\lesssim 500$ GeV, the absolute stability of the potential can be attained only for $|X_{t}| \lesssim \sqrt{ 6 m_{\tilde{t}_1} m_{\tilde{t}_2}}$. The bounds become stronger for larger values of the $μ$ parameter. Note that this is approximately the value of $X_t$ which maximizes the Higgs mass. Our bounds on the low scale MSSM parameters are more stringent than those reported earlier in literature. We reanalyze the stau sector as well, keeping both staus. We study the connections between the observed Higgs rates and vacuum (meta)stability. We show how a precision study of the ratio of signal strengths, ($μ_{γγ}/μ_{ZZ}$) can shed further light.

description: We show how to apply forward and reverse mode Combinatory Homomorphic Automatic Differentiation (CHAD) to total functional programming languages with expressive type systems featuring the combination of - tuple types; - sum types; - inductive types; - coinductive types; - function types. We achieve this by analysing the categorical semantics of such types in $Σ$-types (Grothendieck constructions) of suitable categories. Using a novel categorical logical relations technique for such expressive type systems, we give a correctness proof of CHAD in this setting by showing that it computes the usual mathematical derivative of the function that the original program implements. The result is a principled, purely functional and provably correct method for performing forward and reverse mode automatic differentiation (AD) on total functional programming languages with expressive type systems.

Trade Union Effectiveness in the UK Hospitality Sector: A Case Study Approach
Creators: name: Rahman, Md Suaybur

description: This study investigates how union representation, management attitude, union membership, collective bargaining, and technological revolution affect trade union effectiveness in the UK hospitality industry. It specifically explores how internal organisational factors and trade union factors impact the effectiveness of trade unions in the UK hospitality sector, as well as how improvement in such effectiveness can benefit employers and employees in this sector. An analysis of seven case studies of hotels in the UK was conducted, which included a total of 71 interviews with employees and hotel managers, seven meeting observations, and an analysis of documents from each hotel. All these data were analysed thematically using NVivo 12. Key findings revealed that two hotels were strongly unionised while the rest were weakly unionised. The unionised hotels had strong union representation, bargaining power and an adequate and growing union membership. The weakly unionised hotels had weak bargaining power and declining membership. Workers from weakly unionised hotels began to turn to management efficiency to seek resolutions for their concerns. Conversely, workers from strongly unionised hotels sought union representation to resolve their issues with the management. The study contributes a proposed conceptual framework of trade union effectiveness applied to the seven case organisations.

political changes in Tunisia 2000 -2018

description: The abstract gives an overview over geographical, environmental and political changes in Tunisia from 2000 to 2018. The focus is on wildfire evolution and climate change processes in Tunisia. L' augmentation des incendies de forêts, la littoralisation, la californisation, risque de voir les espèces invasives se multiplier-telle fut le résultat de l'étude GTZ « Stratégie nationale d'adaptation de l'agriculture tunisienne et des écosystèmes aux changements climatiques» sottie en 2007 - et dont l'auteur fut le responsable du groupe d'analyse des écosystèmes. Le diagnostic concernant l'évolution de risques de feux de forêts fut assez alarmant : « Nous pensons que les changements climatiques vont accroître considérablement les risques de feux de végétation. Le Nord de la Tunisie serait particulièrement affecté par cette évolution car en plus de l'augmentation des températures le stock combustible pourrait considérablement augmenter ... La progression des incendies, surtout de grands incendies nécessitant des grands stocks de combustibles, dans le Nord tunisien, peut avoir des conséquences particulièrement négatives pour toute l'économie tunisienne car elle met en danger les systèmes des barrages et l'approvisionnement en eau d'une grande partie de la Tunisie. (Neff, C. 2007., p.37-38)».Dix ans après la sortie de l' étude l' auteur essai d'évaluerà quel point les scenarios dessinés dans l'étude de 2007 sont encore d'actualité en Tunisie contemporaine (2017/18). Est-ce que les changements politiques, la révolution tunisienne de 2011 et la phase transitoire vers une démocratielibérale qui suivait cette révolution, ont pesé sur l' état de l'environnement. Quel est la tendance des fréquences d'incendies de forêts des dernières années en Tunisie. Est-ce que les pouvoirs politiques actuelsprennent en considération les «risques» que les changements climatiques peuvent engendrer pour les écosystèmes& les paysages tunisiennes. Le tout sera complété, par une vue globale d'extérieure sur la Tunisie-l'auteur est bloggeur sur le Monde.fr depuis 2009, et il suit les évènements tunisiens avec attention. Quel est la vue d'un bloggeur franco-allemande sur une Tunisie changeante et confronté à des défis politiques considérable: la phase de transition démocratique, les changements climatiques, mais aussi le futur des terres intérieures tunisiennes, les paysages ruraux à l'abandonet dont la jeunesse cherche à fuir vers des destinations meilleurs ...

description: Menon's identity states that for every positive integer $n$ one has $\sum (a-1,n) = φ(n) τ(n)$, where $a$ runs through a reduced residue system (mod $n$), $(a-1,n)$ stands for the greatest common divisor of $a-1$ and $n$, $φ(n)$ is Euler's totient function and $τ(n)$ is the number of divisors of $n$. Menon's identity has been the subject of many research papers, also in the last years. We present detailed, self contained proofs of this identity by using different methods, and point out those that we could not identify in the literature. We survey the generalizations and analogs, and overview the results and proofs given by Menon in his original paper. Some historical remarks and an updated list of references are included as well.

description: Driving styles summarize different driving behaviors that reflect in the movements of the vehicles. These behaviors may indicate a tendency to perform riskier maneuvers, consume more fuel or energy, break traffic rules, or drive carefully. Therefore, this paper presents a driving style recognition using Interval Type-2 Fuzzy Inference System with Multiple Experts Decision-Making for classifying drivers into calm, moderate and aggressive. This system receives as input features longitudinal and lateral kinematic parameters of the vehicle motion. The type-2 fuzzy sets are more robust than type-1 fuzzy sets when handling noisy data, because their membership function are also fuzzy sets. In addition, a multiple experts approach can reduce the bias and imprecision while building the fuzzy rulebase, which stores the knowledge of the fuzzy system. The proposed approach was evaluated using descriptive statistics analysis, and compared with clustering algorithms and a type-1 fuzzy inference system. The results show the tendency to associate lower kinematic profiles for the driving styles classified with the type-2 fuzzy inference system when compared to other algorithms, which is in line with the more conservative approach adopted in the aggregation of the experts' opinions.

description: Mixtures of skew-t distributions offer a flexible choice for model-based clustering. A mixture model of this sort can be implemented using a variety of formulations of the skew-t distribution. Herein we develop a mixture of skew-t factor analyzers model for clustering of high-dimensional data using a flexible formulation of the skew-t distribution. Methodological details of our approach, which represents an extension of the mixture of factor analyzers model to a flexible skew-t distribution, are outlined and details of parameter estimation are provided. Clustering results are illustrated and compared to an alternative formulation of the mixture of skew-t factor analyzers model as well as the mixture of factor analyzers model.

description: Wrist-driven orthotics have been designed to assist people with C6-7 spinal cord injury, however, the kinematic constraint imposed by such a control strategy can impede mobility and lead to abnormal body motion. This study characterizes body compensation using the novel Tenodesis Grasp Emulator, an adaptor orthotic that allows for the investigation of tenodesis grasping in subjects with unimpaired hand function. Subjects perform a series of grasp-and-release tasks in order to compare normal (test control) and constrained wrist-driven modes, showing significant compensation as a result of the constraint. A motor-augmented mode is also compared against traditional wrist-driven operation, to explore the potential role of hybrid human-robot control. We find that both the passive wrist-driven and motor-augmented modes fulfill different roles throughout various tasks tested. Thus, we conclude that a flexible control scheme that can alter intervention based on the task at hand holds the potential to reduce compensation in future work.

Contrasting Identifying Assumptions of Average Causal Effects: Robustness and Semiparametric Efficiency

description: Semiparametric inference on average causal effects from observational data is based on assumptions yielding identification of the effects. In practice, several distinct identifying assumptions may be plausible; an analyst has to make a delicate choice between these models. In this paper, we study three identifying assumptions based on the potential outcome framework: the back-door assumption, which uses pre-treatment covariates, the front-door assumption, which uses mediators, and the two-door assumption using pre-treatment covariates and mediators simultaneously. We provide the efficient influence functions and the corresponding semiparametric efficiency bounds that hold under these assumptions, and their combinations. We demonstrate that neither of the identification models provides uniformly the most efficient estimation and give conditions under which some bounds are lower than others. We show when semiparametric estimating equation estimators based on influence functions attain the bounds, and study the robustness of the estimators to misspecification of the nuisance models. The theory is complemented with simulation experiments on the finite sample behavior of the estimators. The results obtained are relevant for an analyst facing a choice between several plausible identifying assumptions and corresponding estimators. Our results show that this choice implies a trade-off between efficiency and robustness to misspecification of the nuisance models.
