description: We study the dynamical aspects of dark energy in the context of a non-minimally coupled scalar field with curvature and torsion. Whereas the scalar field acts as the source of the trace mode of torsion, a suitable constraint on the torsion pseudo-trace provides a mass term for the scalar field in the effective action. In the equivalent scalar-tensor framework, we find explicit cosmological solutions representing dark energy in both Einstein and Jordan frames. We demand the dynamical evolution of the dark energy to be weak enough, so that the present-day values of the cosmological parameters could be estimated keeping them within the confidence limits set for the standard $Ł$CDM model from recent observations. For such estimates, we examine the variations of the effective matter density and the dark energy equation of state parameters over different redshift ranges. In spite of being weakly dynamic, the dark energy component differs significantly from the cosmological constant, both in characteristics and features, for e.g. it interacts with the cosmological (dust) fluid in the Einstein frame, and crosses the phantom barrier in the Jordan frame. We also obtain the upper bounds on the torsion mode parameters and the lower bound on the effective Brans-Dicke parameter. The latter turns out to be fairly large, and in agreement with the local gravity constraints, which therefore come in support of our analysis.

description: We consider a two-lead (three-terminal) setup of nonlocal transport through Majorana zero modes (MZMs) and construct a Majorana master equation (which is also valid for small bias voltage). We first carry out representative results of current and then show that a modified Bogoliubov-de Gennes (BdG) treatment can consistently recover the same results. Based on the interplay of the two approaches, we reveal the existence of nonvanishing channels of teleportation and crossed Andreev reflections even at the limit $ε_M\to 0$ (zero coupling energy of the MZMs), which leads to new predictions for the height of the zero-bias-peak of the local conductance and the $ε_M$-scaling behavior of the teleportation conductance, for verification by experiments.

description: Combinatorial Hopf algebras of trees exemplify the connections between operads and bialgebras. Painted trees were introduced recently as examples of how graded Hopf operads can bequeath Hopf structures upon compositions of coalgebras. We put these trees in context by exhibiting them as the minimal elements of face posets of certain convex polytopes. The full face posets themselves often possess the structure of graded Hopf algebras (with one-sided unit). We can enumerate faces using the fact that they are structure types of substitutions of combinatorial species. Species considered here include ordered and unordered binary trees and ordered lists (labeled corollas). Some of the polytopes that constitute our main results are well known in other contexts. First we see the classical permutohedra, and then certain generalized permutohedra: specifically the graph associahedra of suspensions of certain simple graphs. As an aside we show that the stellohedra also appear as liftings of generalized permutohedra: graph composihedra for complete graphs. Thus our results give examples of Hopf algebras of tubings and marked tubings of graphs. We also show an alternative associative algebra structure on the graph tubings of star graphs.

description: Evolutionary algorithms (EAs) have been successfully applied to optimize the policies for Reinforcement Learning (RL) tasks due to their exploration ability. The recently proposed Negatively Correlated Search (NCS) provides a distinct parallel exploration search behavior and is expected to facilitate RL more effectively. Considering that the commonly adopted neural policies usually involves millions of parameters to be optimized, the direct application of NCS to RL may face a great challenge of the large-scale search space. To address this issue, this paper presents an NCS-friendly Cooperative Coevolution (CC) framework to scale-up NCS while largely preserving its parallel exploration search behavior. The issue of traditional CC that can deteriorate NCS is also discussed. Empirical studies on 10 popular Atari games show that the proposed method can significantly outperform three state-of-the-art deep RL methods with 50% less computational time by effectively exploring a 1.7 million-dimensional search space.

Emerging trends in Topological Insulator and Topological Superconductor

description: Topological insulators are new class of materials which are characterized by a bulk band gap like ordinary band insulator but have protected conducting states on their edge or surface. These states emerge out due to the combination of spin-orbit coupling and time reversal symmetry. Also these states are insensitive to scattering by non-magnetic impurities. A two-dimensional (2D) topological insulator has one dimensional (1D) edge states in which the spin-momentum locking of the electrons gives rise to quantum spin Hall effect. A three-dimensional (3D) topological insulator supports novel spin-polarized 2D Dirac fermions on its surface. These topological insulator materials have been theoretically predicted and experimentally observed in a variety of 2D and 3D systems, including $\rm HgTe$ quantum wells, $\rm BiSb$ alloys, and $\rm Bi_{2}Te_{3}$, $\rm Bi_{2}Se_{3}$ crystals. Moreover, proximity induced superconductivity in these systems can lead to a state that supports zero energy Majorana fermion and the phase is known as topological superconductors. In this article, the basic idea of topological insulators and topological superconductors are presented along with their experimental development.

description: This study analyses the current viability of this business based on a sample of European countries in the year 2019; countries where electricity prices (day-ahead market) and financial conditions show a certain degree of heterogeneity. We basically follow a sequence of three analyses in our study. Firstly, a Linear Mixed-Integrated Programming model has been developed to optimize the arbitrage strategy for each country in the sample. Secondly, using the cash-flows from the optimization model, we calculate two financial indicators (NPV and IRR) in order to select the optimal converter size for each country. Tax and discount rates specific to each country have been used with the calculation of this second rate following the methodology proposed by the Spanish regulator. Thirdly, a mixed linear regression model is proposed in order to investigate the importance of observed and unobserved heterogeneity (at country level) in explaining the business profitability.

description: The loss surface of an overparameterized neural network (NN) possesses many global minima of zero training error. We explain how common variants of the standard NN training procedure change the minimizer obtained. First, we make explicit how the size of the initialization of a strongly overparameterized NN affects the minimizer and can deteriorate its final test performance. We propose a strategy to limit this effect. Then, we demonstrate that for adaptive optimization such as AdaGrad, the obtained minimizer generally differs from the gradient descent (GD) minimizer. This adaptive minimizer is changed further by stochastic mini-batch training, even though in the non-adaptive case, GD and stochastic GD result in essentially the same minimizer. Lastly, we explain that these effects remain relevant for less overparameterized NNs. While overparameterization has its benefits, our work highlights that it induces sources of error absent from underparameterized models.
Biofluorescent Worlds II. Biological fluorescence induced by stellar UV flares, a new temporal biosignature

description: Our first targets in the search for signs of life are orbiting nearby M stars, such as the planets in the Proxima Centauri, Ross-128, LHS-1140, and TRAPPIST-1 systems. Future ground-based discoveries, and those from the TESS mission, will provide additional close-by targets. However, young M stars tend to be very active, flaring frequently and causing UV fluxes on the surfaces of HZ planets to become biologically harmful. Common UV-protection methods used by life (e.g. living underground, or underwater) would make a biosphere harder to detect. However, photoprotective biofluorescence, 'up-shifting' UV to longer, safer wavelengths, could increase a biosphere's detectability. Here we model intermittent emission at specific wavelengths in the visible spectrum caused by biofluorescence as a new temporal biosignature for planets around active M stars. We use the absorption and emission characteristics of common coral fluorescent pigments and proteins to create model spectra and colours for an Earth-like planet in such a system, accounting for different surface features, atmospheric absorption, and cloud cover. We find that for a cloud-free planet biofluorescence could induce a temporary change in brightness that is significantly higher than the reflected flux alone, causing up to two orders-of-magnitude change in planet-star contrast, compared to a non-fluorescent state, if the surface is fully covered by a highly efficient fluorescent biosphere. Hence, UV-flare induced biofluorescence presents previously unexplored possibilities for a new temporal biosignature that could be detectable by instruments like those planned for the extremely large telescope and could reveal hidden biospheres.

description: Detecting digital face manipulation has attracted extensive attention due to fake media's potential harms to the public. However, recent advances have been able to reduce the forgery signals to a low magnitude. Decomposition, which reversibly decomposes an image into several constituent elements, is a promising way to highlight the hidden forgery details. In this paper, we consider a face image as the production of the intervention of the underlying 3D geometry and the lighting environment, and decompose it in a computer graphics view. Specifically, by disentangling the face image into 3D shape, common texture, identity texture, ambient light, and direct light, we find the devil lies in the direct light and the identity texture. Based on this observation, we propose to utilize facial detail, which is the combination of direct light and identity texture, as the clue to detect the subtle forgery patterns. Besides, we highlight the manipulated region with a supervised attention mechanism and introduce a two-stream structure to exploit both face image and facial detail together as a multi-modality task. Extensive experiments indicate the effectiveness of the extra features extracted from the facial detail, and our method achieves the state-of-the-art performance.

The main aim of this research was to find the relationship between reward management and employee motivation from contact center professionals of ethio telecom. Data for the study were gathered through questionnaire. A total of 293 questionnaires were distributed, out of which, 275 of them were returned. The collected data was entered into the Statistical Package for Social Sciences (SPSS) for analysis. Descriptive statistics such as mean and standard deviation were used to analyze the data. Regression analysis were used to test the relationship between the variables under study in relation to the objectives of the study. The result indicated there is a significant and positive relationship between all independent variables which are payment, promotion recognition, benefits, work content and working conditions and dependent variable employee motivation. These variables have positive influence on employee work motivation
Children’s developing moral concern for animals
Creators: name: Henseler Kozachenko, Heather
Publisher: name: Lancaster University
Year: 2022

description: Adults tend to morally prioritise animals that share qualities with humans (e.g., intelligence), but they are also self-serving in their judgments of animals they consume. How children value animal life remains largely unexplored. Across four studies, this thesis examined how school-age children and adults evaluate the worth of animal life (Study 1) and judge the wrongness of harming animals (Studies 2-4). In Study 1, 241 children between 6 and 10, and 152 adults, were asked to rate a range of animals on seven different perceptual dimensions and rank order the animals within a moral-regard task. Structural equation modelling revealed several important developmental changes with younger children placing relatively more emphasis on animal aesthetics and benevolence than older children and adults who elevated the intelligence, sentience, and utility of animals as food for humans. Studies 2-3 explored the impact of categorisation and consumer motivations on children’s and adults’ judgments of harming animals. Perceptions of the intelligence of an animal were experimentally manipulated, as well as the animals’ food status (chickens vs. kakapos, Study 2) and the perspective taken by the participant (self vs. other, Study 3). Compared to adults, children tended to hold more moralistic views of harm to animals, irrespective of their status as food (Study 2). Only adults exhibited motivated disregard for the animals’ intelligence when it was an animal consumed (Study 2) or when personally judging its worth (Study 3); for example, adults believed that others would feel guilty about eating intelligent cows, but their own judgments were not affected by admitting cow intelligence. By contrast, children condemned eating cows as much as they believed others would. Study 4 isolated the personal relevance of the eaten animal. It also reduced the role of aesthetics within the materials. This conceptual replication with 223 adults produced very similar results to Study 2, but failed to replicate the motivated use of intelligence information for the non-food animal. This thesis substantially advances how we understand children’s concern for animal life, in that, moral valuations have their basis in childhood that (a) start with a focus on surface-level constructs that develop into more complex understandings of animals’ minds and (b) lack the self-serving evaluative processes characteristic of adults.

description: Con el lanzamiento del modelo GPT-3 de OpenAI, se ha producido toda una revolución en inteligencia artificial, germinando plataformas y aplicaciones que afectan a tareas fundamentales, como la búsqueda y generación de información. Lejos de suponer una amenaza para los profesionales de la información, esta irrupción se presenta como una oportunidad única. Y es que, pese a sus numerosas virtudes, no se puede obviar que estas herramientas carecen de una verdadera inteligencia. Un problema que ha sido señalado por el lingüista Noam Chomsky, quien indica que “this kind of prediction, even when successful, is pseudoscience”. Son de esta manera nuevos los esfuerzos y desafíos que se requieren para integrar con éxito la inteligencia artificial en nuestras tareas rutinarias y hacer un uso correcto y responsable, en lugar de entregarle ciegamente muchas de nuestras tareas. El objetivo de esta comunicación es arrojar luz sobre este espacio por definir y exponer los diferentes roles y tareas que se vislumbran para los profesionales de la información al respecto en este escenario.

description: The use of datasets is getting more relevance in surgical robotics since they can be used to recognise and automate tasks. Also, this allows to use common datasets to compare different algorithms and methods. The objective of this work is to provide a complete dataset of three common training surgical tasks that surgeons perform to improve their skills. For this purpose, 12 subjects teleoperated the da Vinci Research Kit to perform these tasks. The obtained dataset includes all the kinematics and dynamics information provided by the da Vinci robot (both master and slave side) together with the associated video from the camera. All the information has been carefully timestamped and provided in a readable csv format. A MATLAB interface integrated with ROS for using and replicating the data is also provided.

description: We study the thermodynamic phase diagram of three-dimensional $sl(N;\mathbb{R})$ higher spin black holes. By analyzing the semi-classical partition function we uncover a rich structure that includes Hawking-Page transitions to the AdS$_3$ vacuum, first order phase transitions among black hole states, and a second order critical point. Our analysis is explicit for $N=4$ but we extrapolate some of our conclusions to arbitrary $N$. In particular, we argue that even $N$ is stable in the ensemble under consideration but odd $N$ is not.

description: Self-assembly of modular robotic systems enables the construction of complex robotic configurations to adapt to different tasks. This paper presents a framework for SMORES types of modular robots to efficiently self-assemble into tree topologies. These modular robots form kinematic chains that have been shown to be capable of a large variety of manipulation and locomotion tasks, yet they can reconfigure using a mobile reconfiguration. A desired kinematic topology can be mapped onto a planar pattern with optimal module assignment based on the modules' locations, then the mobile reconfiguration assembly process can be executed in parallel. A docking controller is developed to guarantee the success of docking processes. A hybrid control architecture is designed to handle a large number of modules and complex behaviors of each individual, and achieve efficient and robust self-assembly actions. The framework is demonstrated in both hardware and simulation on the SMORES-EP platform.

Cross correlation mediated by distant Majorana zero modes with no overlap

Publisher: name: arXiv

description: Existing studies via shot noise calculation conclude that the cross correlation between the currents in the two leads connected by a pair of Majorana zero modes (MZMs) vanishes when their coupling energy $ε_M\to 0$. Motivated by the intrinsic nature of nonlocality of the MZMs, we revisit this important problem and propose an experimental scheme to demonstrate the nonvanishing cross correlation even at the limit $ε_M\to 0$. The proposed scheme employs the Andreev-process-associated branch circuit currents, which are theoretically obtained by applying a decomposition analysis for the total currents while in practical measurement, are accessible directly. For different bias voltage setup, we find intriguing results of both negative and positive correlations and carry out simple physical understanding using a quantum jump technique. Importantly, combining together with the evidence of the zero-bias-peak of conductance, the nonlocal cross correlation predicted in this work can help to definitely confirm the existence of the nonlocal MZMs.

description: Many bird species incorporate anthropogenic materials (e.g. sweet wrappers, cigarette butts and plastic strings) into their nests. Anthropogenic materials have become widely available as nesting materials in marine and terrestrial environments globally. These human-made objects can provide important benefits to birds such as serving as reliable signals to conspecifics or protecting against ectoparasites, but they can also incur fundamental survival and energetic costs via offspring entanglement and reduced insulative properties, respectively. From an ecological perspective, several hypotheses have been proposed to explain the use of anthropogenic nest materials (ANMs) by birds but no previous interspecific study has tried to identify the underlying mechanisms of this behaviour. In this study, we performed a systematic literature search and ran phylogenetically controlled comparative analyses to examine interspecific variation in the use of ANM and to examine the influence of several ecological and life-history traits. We found that sexual dimorphism and nest type significantly influenced the use of ANMs by birds providing support for the ‘signalling hypothesis’ that implies that ANMs reflect the quality of the nest builder. However, we found no support for the ‘age’ and ‘new location’ hypotheses nor for a phylogenetic pattern in this behaviour, suggesting that it is widespread throughout birds.This article is part of the theme issue ‘The evolutionary ecology of nests: a cross-taxon approach’.
On rings of supersymmetric polynomials

description: We consider three types of rings of supersymmetric polynomials: polynomial ones $Λ_{m,n}$, partially polynomial $Λ_{m,n}^{+y}$ and Laurent supersymmetric rings $Λ_{m,n}^{\pm}$. For each type of rings we give their descriptions in terms of generators and relations. As a corollary we get for $n\ge m$ an isomorphism $Λ_{m,n}^{+y}=Λ_{m,m}^{+y}\otimesΛ^{+y}_{0,n-m}$. We also have the same sort of isomorphism for polynomial rings, but in this case the isomorphism does not preserve the grading. For each type of rings we also construct some natural basis consisting of Euler characters.

Distributed nonparametric regression imputation for missing response problems with large-scale data

description: Nonparametric regression imputation is commonly used in missing data analysis. However, it suffers from the ``curse of dimension". The problem can be alleviated by the explosive sample size in the era of big data, while the large-scale data size presents some challenges on the storage of data and the calculation of estimators. These challenges make the classical nonparametric regression imputation methods no longer applicable. This motivates us to develop two distributed nonparametric regression imputation methods. One is based on kernel smoothing and the other on the sieve method. The kernel-based distributed imputation method has extremely low communication cost and the sieve-based distributed imputation method can accommodate more local machines. To illustrate the proposed imputation methods, response mean estimation is considered. Two distributed nonparametric regression imputation estimators are proposed for the response mean, which are proved to be asymptotically normal with asymptotic variances achieving the semiparametric efficiency bound. The proposed methods are evaluated through simulation studies and are illustrated by a real data analysis.
