description: Using Brownian dynamics simulations, we systematically study the effective interaction between two parallel hard walls in a 2D suspension of self-propelled (active) colloidal hard spheres, and we find that the effective force between two hard walls can be tuned from a long range repulsion into a long range attraction by changing the density of active particles. At relatively high densities, the active hard spheres can form a dynamic crystalline bridge, which induces a strong oscillating long range dynamic wetting repulsion between the walls. With decreasing density, the dynamic bridge gradually breaks, and an intriguing long range dynamic depletion attraction arises. A similar effect occurs in a quasi-2D suspension of self-propelled colloidal hard spheres by changing the height of the confinement. Our results open up new possibilities to manipulate the motion and assembly of microscopic objects by using active matter.

description: Το κουκλοθέατρο στην εκπαίδευση έχει αποδείξει τη σημασία του στην ολόπλευρη ανάπτυξη του παιδιού, καθώς χάρη στην παιδοκεντρική του προσέγγιση, βοηθάει τα παιδιά, να γνωρίσουν βαθύτερα τον εαυτό τους και να οδηγηθούν στην αποδοχή και εξωτερίκευσή του. Ενώ αλληλεπιδρούν με τους συμμαθητές τους, δημιουργούν ουσιαστικές σχέσεις, με βάση τη συνεργασία και τον διάλογο. Το κουκλοθέατρο αποτελεί μια ιδιαίτερη μορφή επικοινωνίας, ένα μέσο κοινωνικοποίησης και καλλιέργειας της κοινωνικής αλληλεπίδρασης, ακόμα και για τα πιο κλειστά παιδιά. Κατ’ αυτόν τον τρόπο, μπορεί να συμβάλλει στην αποδοχή των παιδιών από την ομάδα των συνομήλικων στην προσχολική ηλικία. Στη συγκεκριμένη εργασία διερευνάται αν και πόσο το κουκλοθέατρο δύναται να επιδράσει στην ενίσχυση της αποδοχής από τους συνομήλικους. Στηρίζεται, κυρίως, στην ίδια την τέχνη του κουκλοθέατρου ως καλλιτεχνική εκπαίδευση και όχι ως εκπαιδευτικό εργαλείο στα χέρια του νηπιαγωγού. Η παρούσα μελέτη πρόκειται για μια πειραματική έρευνα που διερευνά, κατά πόσο 12 παρεμβάσεις κουκλοθέατρου θα ενισχύσουν την αποδοχή από τους συνομήλικους σε μαθητές προσχολικής ηλικίας.

description: We work in the smooth category. The following problem was suggested by E. Rees in 2002: describe the precomposition action of self-diffeomorphisms of S^p x S^q on the set of isotopy classes of embeddings S^p x S^q -> R^m. Let g : S^p x S^q -> R^m be an embedding such that g |_{a x S^q} : a x S^q -> R^m - g (b x S^q) is null-homotopic for some pair of different points a,b in S^p. Theorem. If h is an autodiffeomorphism of S^p x S^q identical on a neighborhood of a x S^q for some a\in S^p and p R^m, g : S^p x S^q -> R^m isotopy classes of embeddings. As a corollary we obtain that under certain conditions for orientation-preserving embeddings s : S^p x D^q -> N the S^p-parametric embedded connected sum f#_sg depends only on f,g and the homology class of s|_{S^p x 0}.

description: The recording of this talk can be streamed on YouTube. The Research Engineering Group at The Alan Turing Institute started our RSE journey in autumn 2016 as a new team in a new institute. Without the usual constraints and advantages of RSE groups based in universities, the team has had to find its path for sustainable existence in a rapidly evolving institute and field. In half a decade the team has grown from 3 to 36 members, going through a few rounds of refining our roles, the way we recruit new members, and how we support members of the team to progress into their next role - whether at the Turing or beyond. The journey has been guided by our principles: transparency in leadership and decisions; diversity of talent, people and experience; supporting individuals in their career journey; and focus on our role as expert collaborators. In this talk, we aim to share our journey, the successes, the false starts and the lessons learned.

description: Mixed, charge and heat current fluctuations as well as thermoelectric differential conductances are considered for non-interacting nanosystems connected to reservoirs. Using the Landauer-Buttiker formalism, we derive general expressions for these quantities and consider their possible relationships in the entire ranges of temperature, voltage and coupling to the environment or reservoirs. We introduce a dimensionless quantity given by the ratio between the product of mixed noises and the product of charge and heat noises, distinguishing between the auto-ratio defined in the same reservoir and the cross-ratio between distinct reservoirs. From the linear response regime to the high-voltage regime, we further specify the analytical expressions of differential conductances, noises and ratios of noises, and examine their behavior in two concrete nanosystems: a quantum point contact in an ohmic environment and a single energy level quantum dot connected to reservoirs. In the linear response regime, we find that these ratios are equal to each other and are simply related to the figure of merit. They can be expressed in terms of differential conductances with the help of the fluctuation-dissipation theorem. In the non-linear regime, these ratios radically distinguish between themselves as the auto-ratio remains bounded by one, while the cross-ratio exhibits rich and complex behaviors. In the quantum dot nanosystem, we moreover demonstrate that the thermoelectric efficiency can be expressed as a ratio of noises in the non-linear Schottky regime. In the intermediate voltage regime, the cross-ratio changes sign and diverges, which evidences a change of sign in the heat cross-noise.

Validating experimental results from articles has finally become a norm at many systems and ML conferences. Nowadays, more than half of accepted papers pass artifact evaluation and share related code and data. Unfortunately, lack of a common experimental framework, common research methodology, and common formats places an increasing burden on evaluators to validate a growing number of ad-hoc artifacts. Furthermore, having too many ad-hoc artifacts and Docker snapshots is almost as bad as not having any (!), since they cannot be easily reused, customized and built upon.

While overviewing more than 100 papers during artifact evaluation at PPoPP, CGO, PACT, Supercomputing, and other conferences, we noticed that many of them use similar experimental setups, benchmarks, models, data sets, environments and platforms. This motivated us to develop Collective Knowledge (CK), an open workflow framework with a unified Python API to automate common researchers’ tasks such as detecting software and hardware dependencies, installing missing packages, downloading data sets and models, compiling and running programs, performing autotuning and co-design, crowdsourcing time-consuming experiments across computing resources provided by volunteers similar to SETI@home, applying statistical analysis and machine learning, validating results and plotting them on a common scoreboard for open and fair comparison, automatically generating interactive articles, and so on: cKnowledge.org.

In this presentation, we will introduce CK concepts and present several real-world use cases from General Motors and Arm

on collaborative benchmarking, autotuning and co-design of efficient software/hardware stacks for deep learning. We also present results and reusable CK components from the 1st ACM ReQuEST optimization tournament: http://cKnowledge.org/request. Finally, we introduce our latest initiative to create an open repository of reusable research components and workflows to reboot and accelerate open science, quantum computing, and AI!

In our main results we prove spectral asymptotics formulae with refined remainder estimates for the singular values of the resolvent difference between the standard self-adjoint realizations and the operators with a $δ$ and $δ^\prime$-interaction, respectively. Our technique makes use of general pseudodifferential methods, classical results on spectral asymptotics of $ψ$do's on closed manifolds and Krein-type resolvent formulae.

description: This doctoral dissertation aims to highlight the poetic work of an important intellectual figure of the 11th century, Ioannis Mauropous. Through the study of secular and religious poems of a wide range of topics (autobiographical, laudatory, epitaphs, epigrams in works of art, etc.), beyond an image of the poet's particular writing characteristics, issues will arise related to social and cultural backround of 11th century that he lived through. The PhD thesis consists of four parts. The introduction presents information about the life and work of the author, as well as the historical, social and cultural context of his time. The next section is the classification of the poems into ideological and thematic categories, while the same section includes information about language, rhetoric, narrative techniques, metrics and manuscript tradition of the poems. The second part presents the critical edition of the poems accompanied by the apparati (critical and literary), and a parallel translation in modern Greek. The third part involves a multi-level (historical, philological and prosopographical) commentary of the poems, and the last section contains four indices (Index nominum, Index verborum notabilium, Index locorum and Index initiorum carminum), as well as the image epimeter.

description: The ESR model has been recently proposed in several papers to offer a possible solution of the problems raising from the nonobjectivity of physical properties in quantum mechanics (QM) (mainly the objectification problem of the quantum theory of measurement). This solution is obtained by embodying the mathematical formalism of QM into a broader mathematical framework and reinterpreting quantum probabilities as conditional on detection rather than absolute. We provide a new and more general formulation of the ESR model and discuss time evolution according to it, pointing out in particular that both linear and nonlinear evolution may occur, depending on the physical environment.

Senegal
Europe

description: Senegal has been a country of migration since the 1970s (15 million inhabitants/over 2.5 million diaspora members). Although most Senegalese emigrate within Africa, 41% of all Senegalese emigrants live in Europe. This report is drawn up on the basis of research carried out in Senegal between 2020 and 2021 and is one of the outputs of the FUME research project. Its objective is twofold: to illustrate the main environmental, demographic, socio-cultural, economic and geopolitical characteristics and patterns that, from the local to the regional and international level, shape internal and international Senegalese migration trajectories; to analyse the results of the research undertaken in the Dakar region, including 30 in-depth interviews with potential migrants and 6 semi-structured interviews with migration experts. The report is structured in three parts. The introductory part sets out the objectives and justifications of the study, followed by the presentation of the main theoretical and methodological approaches adopted. The second part of the report is devoted to the presentation of the context of analysis. It is organized around six chapters which provide an updated overview of the country. The first chapter of this second part illustrates the environmental characteristics of Senegal and describes the main changes in terms of population mobility dynamics at the national and regional levels. The second chapter consists of a demographic description of the past and present situation of the population, with particular attention to the main trends that are likely to influence the composition of future demographic patterns. The third chapter focuses on the socio-cultural characteristics that shape the composition and profile of the Senegalese population. The key topics taken into consideration are the role of education, social networks (e.g., family ties, religious, cultural and migration networks) and the socio-cultural roots of the propensity to move. The fourth chapter provides an overview of Senegal’s economic context, limiting its focus to regional development patterns. The fifth chapter provides a brief overview of the political context in Senegal. Particular attention is paid to geopolitical dynamics and political divisions, as well as current conditions concerning security and respect for human rights. The focus of the next chapter is on presenting the main migration policies implemented at the national level, aimed at internal mobility and international mobility to the European Union. In this sixth chapter, a final section is dedicated to the presentation of the main migration patterns in the Dakar region, the selected city of the research. The third part of the report focuses on analysing the information provided by the interviewees, potential migrants and key experts.

title: Analysis of experimental designs with unequal group variances.
Creators: name: Talukder, M. A. H
Publisher: name: University of Kent
Year: 1976

description: This thesis deals with weighted (generalised) least squares estimation and analysis for some common experimental designs with the error variance heteroscedastic with respect to the levels of one factor, namely, the treatments or (for split-plot designs) sub-plot treatments. The simple regression model with error variance heteroscedastic with respect to the values of the independent variable, is also considered briefly. The observations in any of the analyses considered are grouped in such a way that the error variance is constant within groups but varies from group to group. On the assumption that the group variances are known, the weighted least squares estimators of the linear parameters and the corresponding analysis (Aitken, 1934-35; Plackett, I960, pp. 47-49) are provided for each design or model. An expression for joint confidence intervals of parametric contrasts for the heteroscedastic models is also obtained. The estimators of the linear parameters and other statistics usually involve actual weights, the reciprocals of the group variances. The actual weights are not usually known. The estimators of the group variances are therefore derived for each design or model. for some designs, the minimum norm quadratic unbiased estimators (Rao, 1970; 1973, pp. 303-305) of group variances are independently distributed as multiples of x2. For other designs, almost unbiased estimators (Horn et al., 1975) of group variances have negligible bias and are approximately independently distri-buted as multiples of x2 Reciprocals of these estimators are used as the estimated weights. The weighted least squares estimators of the linear parameters or variance components and other statistics including test-statistics using estimated weights, are generally biased. It is shown in the thesis how a major part of the bias can be removed; the procedure stems from a theorem due to Meier (1953). The estimators and other statistics using estimated weights are adjusted accordingly. A modified form of this theorem is also proved for correlated estimators of the group variances. A small Monte Carlo study conducted for completely randomised designs showed that the performances of the adjusted statistics are more or less satisfactory. The designs and models covered in this thesis are: completely randomised designs, the general two-way model with proportional cell frequencies, general block designs, randomised complete block designs, latin square designs, split-plot designs with two treatment factors and the linear regression model. For the first three designs, both the fixed-effects models and random or mixed models are considered whereas only the fixed-effects models are dealt with for the remaining three designs.

Correlated trajectories in semiclassical approaches to quantum chaos
Creators: name: Kuipers, Jack
Publisher: name: Universität Regensburg
Year: 2008
Subjects: subject: 510 Mathematik

description: This thesis is concerned with the application and extension of semiclassical methods, involving correlated trajectories, that were recently developed to explain the observed universal statistics of classically chaotic quantum systems. First we consider systems that depend on an external parameter that does not change the symmetry of the system. We study correlations between the spectra at different values of the parameter, a scaled distance $x$ apart, via the parametric spectral form factor $K(\tau,x)$. Using a semiclassical periodic orbit expansion, we obtain a small $\tau$ expansion that agrees with random matrix theory for systems with and without time reversal symmetry. Then we consider correlations of the Wigner time delay in open systems. We study a form factor $K(\tau,x,y,M)$ that depends on the number of scattering channels $M$, the non-symmetry breaking parameter difference $x$ and also a symmetry breaking parameter $y$. The Wigner time delay can be expressed semiclassically in terms of the trapped periodic orbits of the system, and using a periodic orbit expansion we obtain several terms in the small $\tau$ expansion of the form factor that are identical to those calculated from random matrix theory. The Wigner time delay can also be expressed in terms of scattering trajectories that enter and leave the system. Starting from this picture, we derive all terms in the periodic orbit formula and therefore show how the two pictures of the time delay are related on a semiclassical level. A new type of trajectory correlation is derived which recreates the terms from the trapped periodic orbits. This involves two trajectories approaching the same trapped periodic orbit closely - one trajectory approaches the orbit and follows it for several traversals, while its partner approaches in almost the same way but follows the periodic orbit an additional number of times.

description: In order to sample from a given target distribution (often of Gibbs type), the Monte Carlo Markov chain method consists in constructing an ergodic Markov process whose invariant measure is the target distribution. By sampling the Markov process one can then compute, approximately, expectations of observables with respect to the target distribution. Often the Markov processes used in practice are time-reversible (i.e., they satisfy detailed balance), but our main goal here is to assess and quantify how the addition of a non-reversible part to the process can be used to improve the sampling properties. We focus on the diffusion setting (overdamped Langevin equations) where the drift consists of a gradient vector field as well as another drift which breaks the reversibility of the process but is chosen to preserve the Gibbs measure. In this paper we use the large deviation rate function for the empirical measure as a tool to analyze the speed of convergence to the invariant measure. We show that the addition of an irreversible drift leads to a larger rate function and it strictly improves the speed of convergence of ergodic average for (generic smooth) observables. We also deduce from this result that the asymptotic variance decreases under the addition of the irreversible drift and we give an explicit characterization of the observables whose variance is not reduced reduced, in terms of a nonlinear Poisson equation. Our theoretical results are illustrated and supplemented by numerical simulations.

description: The Ehrenfest time scale in quantum transport separates essentially classical propagation from wave interference and here we consider its effect on the transmission and reflection through quantum dots. In particular we calculate the Ehrenfest time dependence of the next to leading order quantum corrections to the transmission and reflection for dc- and ac-transport and check that our results are consistent with current conservation relations. Looking as well at closed systems, we finally demonstrate how the contributions analyzed here imply changes in the calculation given in [P. W. Brouwer, S. Rahav and C. Tian, Phys. Rev. E, 74, 066208 (2006)] of the next to leading order of the spectral form factor. Our semiclassical result coincides with the result obtained in [C. Tian and A. I. Larkin, Phys. Rev. B, 70, 035305 (2004)] by field-theoretical methods.

description: Transformation of CMB photons into light pseudoscalar particles at post big bang nucleosynthesis epoch is considered. Using the present day value of a large scale magnetic field to estimate it at earlier cosmological epochs, the oscillation probability of photons into light pseudoscalar particles with an account of coherence breaking in cosmological plasma is calculated. Demanding that the photon transformation does not lead to an exceedingly large CMB spectral distortion and temperature anisotropy, the constraints on the coupling constant of axion like particles to photons, $ g_{ϕγ} B \lesssim (10^{-15} - 10^{-12}) \textrm{nG}\times \textrm{GeV}^{-1}$, are found for the axion like particle mass in the interval $10^{-25}$ eV $\lesssim m_ϕ\lesssim 10^{-5}$ eV, where $B$ is the strength of the large scale magnetic field at the present time. Our results update the previously obtained ones since we use the density matrix formalism which is more accurate than the wave function approximation for the description of oscillations with an essential coherence breaking. In the axion like particle mass range $10^{-25}$ eV $\lesssim m_ϕ\lesssim 10^{-14}$ eV, weaker limits, by at least 2 orders of magnitude $g_{ϕγ} B \lesssim 10^{-11}\textrm{nG}\times \textrm{GeV}^{-1}$, are obtained in comparison with the wave function approximation. In the mass range $10^{-14}$ eV $\lesssim m_ϕ\lesssim 10^{-5}$ eV, on the other hand, limits that are stronger, by more than an order of magnitude are obtained. Our results are derived by using upper limits on spectral distortion parameter $μ$ and temperature anisotropy $ΔT/T$ found by COBE and expected sensitivities by PIXIE/PRISM.

description: The quantum relative entropy is known to play a key role in determining the asymptotic convertibility of quantum states in general resource-theoretic settings, often constituting the unique monotone that is relevant in the asymptotic regime. We show that this is no longer the case when one allows stochastic protocols that may only succeed with some probability, in which case the quantum relative entropy is insufficient to characterize the rates of asymptotic state transformations, and a new entropic quantity based on a regularization of the Hilbert projective metric comes into play. Such a scenario is motivated by a setting where the cost associated with transformations of quantum states, typically taken to be the number of copies of a given state, is instead identified with the size of the quantum memory needed to realize the protocol. Our approach allows for constructing transformation protocols that achieve strictly higher rates than those imposed by the relative entropy. Focusing on the task of resource distillation, we give broadly applicable strong converse bounds on the asymptotic rates of probabilistic distillation protocols, and show them to be tight in relevant settings such as entanglement distillation with non-entangling operations. This generalizes and extends previously known limitations that only applied to deterministic protocols. Our methods are based on recent results for probabilistic one-shot transformations as well as a new asymptotic equipartition property for the projective relative entropy.

description: We report the observation of coherent oscillations in conversion efficiency of weakly-bound dimers formed from a thermal gas of ultracold atoms. Finite thermal energy of the gas causes loss of coherence when a broad continuum is resonantly coupled to a discrete bound state. Restoration of the coherence can be achieved through non-adiabatic transitions of the dressed molecular energy level that are induced by a strong modulation pulse with fast envelope dynamics. Conditions to observe coherent oscillations are verified, and control of their properties is demonstrated. The main experimental findings are supported by theoretical modeling and numerical calculations. The observed results may lead to a renewed interest in general studies of a discrete energy level coupled to a broadband continuum when the properties of both are fully controlled.

description: The purpose of the present study was to predict emotional intelligence based on the Prosocial Personality in people aged 16 to 56 living in Tehran during the COVID-19 era with descriptive and correlational methods. 92 people (43 women and 49 men) were selected from among the 16 to 56-year-old people living in Tehran during the COVID-19 period of 1400-1401 as the available sample. Data collection was in library and field. Research tools included emotional intelligence questionnaire (MSEIS) and Prosocial Personality (PSB). Due to the spread of the COVID-19 virus and to prevent the spread of the disease, relevant questionnaires were created through the Porsall system, and the link was provided to the participants for answering. The research data was analyzed using SPSS-26 software with two methods of descriptive statistics and inferential statistics. In descriptive statistics, mean, standard deviation, frequency tables and relevant charts were used, and in inferential statistics, according to the research method, regression and Pearson tests were used to check research hypotheses. The results of the regression test of the main hypothesis of emotional intelligence and Prosocial Personality are significant (r=0.000) and Prosocial Personality predicts 14% of emotional intelligence changes in people. Also, the sub-hypotheses of the research showed that there is a positive and significant relationship between emotional intelligence and its dimensions, including evaluation of emotions in oneself and others, regulation of emotions and perception and understanding of emotions with a Prosocial Personality with a probability of 99% (P<0.01).

description: Using ab initio density functional theory (DFT), we demonstrated the possibility of controlling the magnetic ground-state properties of bilayer CrCl$_{3}$ by means of mechanical strains and electric fields. In principle, we investigated the influence of these two fields on parameters describing the spin Hamiltonian of the system. The obtained results show that biaxial strains change the magnetic ground state between ferromagnetic (FM) and antiferromagnetic (AFM) phases. The mechanical strain also affects the direction and amplitude of the uniaxial magnetic anisotropy (MAE). Importantly, the direction and amplitude of the Dzyaloshinskii-Moriya vectors are also highly tunable under external strain and electric fields. The competition between nearest neighbor interaction, MAE, and Dzyaloshinskii-Moriya interactions can lead to the stabilization of various exotic spin textures and novel magnetic excitations. The high tunability of magnetic properties by external fields makes bilayer CrCl$_{3}$ a promising candidate for application in the emerging field of two-dimensional quantum spintronics and magnonics.
