description: The persistent and switchable polarization of ferroelectric materials based on HfO$_2$-based ferroelectric compounds, compatible with large-scale integration, are attractive synaptic elements for neuromorphic computing. To achieve a record current density of 0.01 A/cm$^2$ (at a read voltage of 80 mV) as well as ideal memristive behavior (linear current-voltage relation and analog resistive switching), devices based on an ultra-thin (2.7 nm thick), polycrystalline HfZrO$_4$ ferroelectric layer are fabricated by Atomic Layer Deposition. The use of a semiconducting oxide interlayer (WO$_{x<3}$) at one of the interfaces, induces an asymmetric energy profile upon ferroelectric polarization reversal and thus the long-term potentiation / depression (conductance increase / decrease) of interest. Moreover, it favors the stable retention of both the low and the high resistive states. Thanks to the low operating voltage (<3.5 V), programming requires less than 10${^-12}$ J for 20 ns long pulses. Remarkably, the memristors show no wake-up or fatigue effect.

description: The main aim of models has never been to provide numbers, but insights. Still, challenges prevail for modelers to use the best configuration of their models to provide helpful insights. In the case of energy system modelling, this becomes even more complicated due to increasing complexity of the energy system transition through the potential and need for sector coupling. This paper therefore showcases specific characteristics and challenges for energy system modelling of 100% renewable scenarios. The findings are based on various applications and modifications of the framework GENeSYS-MOD examining different regional characteristics for high renewable configurations in the world, China, India, South-Africa, Mexico, Europe, Germany, and Colombia. The paper elaborates on our experiences of the last years of choosing the best, yet still computable, configuration of GENeSYS-MOD with respect to spatial and time resolution as well as sufficient detailed description of the energy system transition effects. The aim of this paper is therefore twofold, to better understand and interpret existing models as well as to improve future modeling exercises.

description: We explore the Mellin representation of correlation functions in conformal field theories in the weak coupling regime. We provide a complete proof for a set of Feynman rules to write the Mellin amplitude for a general tree level Feynman diagram involving only scalar operators. We find a factorised form involving beta functions associated to the propagators, similar to tree level Feynman rules in momentum space for ordinary QFTs. We also briefly consider the case where a generic scalar perturbation of the free CFT breaks conformal invariance. Mellin space still has some utility and one can consider non-conformal Mellin representations. In this context, we find that the beta function corresponding to conformal propagator uplifts to a hypergeometric function.

description: This study deals with women's participation and challenges faced in leadership positions of private insurance companies. The objective of this study is to identify the factors that affect women's participation in leadership positions in private insurance companies and addressing policy interventions and strategies to improve women leaders' leadership and competences. The subjects of the study were 15 women/men in top leadership, 125 senior employees who are not in managerial position, 55 women in middle managerial level(Branch managers) and 100 selected customers of the insurance companies for the study(Africa, United, Nyala, Nile, Nib, Lion, ELGI, Tsehay). The randomly selected sample sizes are mutually exclusive. Besides, documents were reviewed to supplement the data that collected from primary source. The instruments for data collection were interview, questionnaires and document analysis. The collected data were analyzed both qualitatively by using words and quantitatively by using frequency and percentage. As per the findings in the study, qualified women representation in selected private insurance companies are 51% where as the representation in middle leadership positions and top leadership positions are 16% and 11% respectively. The United Insurance Company has contributed for women participation in leadership as the only company in the industry which lead by Women executive and has 36% of the top level leadership position are occupied by women. Therefore, the study identifies different barriers for women's participation in leadership. The most frequently mentioned barriers by the 265(15 interviewees, 39 middle women leaders, 116 employees not in managerial positions and 95 customers) respondents are women's low access and success to advanced education, socio cultural barrier and lack of support and mentoring in the industry. The main contributing factors for few women's holding of leadership positions are their performance and capability level, their educational qualifications, family support. Finally, the main measures to be taken to enhance women's participation in leadership is mainly depends on better addressing gender gaps in the country and the level of attention given for gender issues in the insurance industry. To address the gender gap women themselves should create net working, support/encourage and mentoring each other and ready to enhance advanced education.

description: The growth of correlation lengths in equilibrium glass-forming liquids near the glass transition is considered a critical finding in the quest to understand the physics of glass formation. These understandings helped us understand various dynamical phenomena observed in supercooled liquids. It is known that at least two different length scales exist - one is of thermodynamic origin, while the other is dynamical in nature. Recent observations of glassy dynamics in biological and synthetic systems where the external or internal driving source controls the dynamics, apart from the usual thermal noise, led to the emergence of the field of active matter. A question of whether the physics of glass formation in these active systems is also accompanied by growing dynamic and static lengths is indeed timely. In this article, we probe the growth of dynamic and static lengths in a model active glass system using rod-like elongated probe particles, an experimentally viable method. We show that the dynamic and static lengths in these non-equilibrium systems grow much more rapidly than their passive counterparts. We then offer an understanding of the violation of the Stokes-Einstein relation and Stokes-Einstein-Debye relation using these lengths via a scaling theory.

description: The European Green Deal has been heralded as the“Europe's man on the moon moment” as it aims to achieve 100% GHG reductions by 2050. Achieving the decarbonization of the energy system will be driven by a combination of factors and synergies between technological development, policy exertion and societal attitudes. In this paper, we present an original set of future storylines until the year 2050 to inspire modelers, policy makers, industry actors, and the public to understand: Without technological developments in the next decades, to what extent can we rely on societal commitment or stronger cooperation within the EU to achieve climate targets? What technological innovations could become a cornerstone of an effective European energy transition? Through analyzing four pathways (shaped by the crossroads of policy-technology-society developments), results indicate that high electrification rates are imminent to achieve a rapid decarbonization. This implies that technology development and deployment must go hand-in-hand with strong policy enforcement in the short-term to speed-up the energy transition. Then, based on a review of European energy transition scenarios, these and other insights are compared vis-à-vis with other scenarios studies to identify similarities of pathway results and to elaborate on consolidated findings relevant to the EU Green Deal.

description: We employ electrostatic conversion drift calculations to match CCD pixel signal covariances observed in flat field exposures acquired using candidate sensor devices for the LSST Camera. We thus constrain pixel geometry distortions present at the end of integration, based on signal images recorded. We use available data from several operational voltage parameter settings to validate our understanding. Our primary goal is to optimize flux point-spread function (FPSF) estimation quantitatively, and thereby minimize sensor-induced errors which may limit performance in precision astronomy applications. We consider alternative compensation scenarios that will take maximum advantage of our understanding of this underlying mechanism in data processing pipelines currently under development. To quantitatively capture the pixel response in high-contrast/high dynamic range operational extrema, we propose herein some straightforward laboratory tests that involve altering the time order of source illumination on sensors, within individual test exposures. Hence the word {\it hysteretic} in the title of this paper.

description: Recent European and German climate targets call for a faster power system transition towards variable renewable energy sources. With the increasing importance of Open Science, several Open Source models have been developed in recent years. However, only a few studies exist that compare their performance against each other. Therefore, this study performs a comprehensive model comparison of five mature Open Source power sector models. For this purpose, we apply eight fully harmonized and simplified one-year scenarios for the German power sector, to analyze deviations in model results. First, an in-depth analysis of two base scenarios for 2016 and 2030 reveals that linear programming-based models differ substantially from models with pre-implemented dispatch orders. Other deviations occur across all models and are mainly caused by the indifferent use of flexibility options such as storage and transmission. Second, variations of parameters and characteristics with a political significance are individually applied to the 2030 base scenario to identify their impact on model results. This includes CO2 emission budgets, increased demands by sector coupling, coal exit strategies, and renewable generation shares. The results prove that some models are far more sensitive to these parameters than others, and renewable generation shares alone are not sufficient to reach desired effects in emission reductions. Finally, a comprehensive scenario for 2030 combines all measures to evaluate general trends that result from the most recent updates in German energy policy. Model results indicate that the new targets require substantially increased investments into renewable generation capacities, storage, and transmission.

description: D3-brane solutions of type IIB supergravity can be obtained by means a classical ansatz involving a harmonic warp factor and two summands, the first being the flat Minkowskian metric of the D3 brane world-sheet and the second a Ricci flat metric on a suitable 6-dimensional transverse space, both twisted by the warp factor. Of particular interest is the case of the total space of thecanonical bundle over a complex Kähler 2-fold. This situation emerges in many cases while considering the resolution of finite quotient singulaties. When the group is $\mathbb{Z}_4$, the complex 2-fold is the second Hirzebruch surface endowed with a Kähler metric having SU(2)xU(1) isometry. There is actually an entire class of such metrics parameterized by a single function, and best described in the AMSY symplectic formalism. We recover the existence of a two parameter subclass of Kähler-Einstein metrics on manifolds that are homeorphic to $S^2\times S^2$, and study in detail this class. The K"ahler-Einstein nature of these manifolds allows the construction of the Ricci flat metric on their canonical bundle via the Calabi Ansatz, which we recast in the AMSY formalism deriving some new elegant formulae. Furthermore we show the full integrability of the differential system of geodesics equations thanks to an additional conserved quantity that we unveil and which is similar to the Carter constant in the case of the Kerr metric.

description: Steered molecular dynamics (SMD) simulations for the calculation of free energies are well suited for high-throughput molecular simulations on a distributed infrastructure due to the simplicity of the setup and parallel granularity of the runs. However, so far, the computational cost limited the estimation of the free energy typically over just a few pullings, thus impeding the evaluation of statistical uncertainties involved. In this work, we performed two thousand pulls for the permeation of a potassium ion in the gramicidin A pore by all-atom molecular dynamics in order to assess the bidirectional SMD protocol with a proper amount of sampling. The estimated free energy profile still shows a statistical error of several kcal/mol, while the work distributions are estimated to be non-Gaussian at pulling speeds of 10 Å/ns. We discuss the methodology and the confidence intervals in relation to increasing amounts of computed trajectories and how different permeation pathways for the potassium ion, knock-on and sideways, affect the sampling and the free energy estimation.

Year: 2019

description: In a knowledge society, organisations need to develop competitive advantages through the effective utilization of electronic marketing in order to succeed in markets. The purpose of this study was to investigate factors affecting e-marketing adoption on Ethiopian supermarkets. Data were collected from 107 Ethiopian supermarkets and the data was collected through a cross-sectional survey design as it is instrumental in collecting data from a population of interest at one point in time. Variables were tested for their relationship with e-marketing adoption using correlation and regression analysis by applying statistical package for social sciences (SPSS). The findings of the study indicate that the proposed model explains 86.4 per cent of the variance of e-marketing adoption. It was found that competitive pressure, adoption cost and IT infrastructure are the most influencing factors of e-marketing adoption. Among them, competitive pressure was proved to be the most significant factor. On the other hand, Owners or managers IT knowledge and governmental support influence but not as strongly as the other three attributes. From these, adoption cost is an inhibitor of the adoption of e-marketing. Therefore, it is recommended that managers, particularly owners of the supermarkets, should be convinced that e-marketing adoption is necessary to maintain and achieve competitive advantage while non-adoption of an e-marketing innovation that is adopted by others in such an environment may result in competitive disadvantage since competitive pressure was proved to be the most significant factors of e-marketing adoption. The researcher further suggested that future research could be conducted with longitudinal data and on a wider scale on all supermarkets in the country cutting across all the counties by collecting data from customers, users of the e-commerce platforms and various other stakeholders

description: Thermoset resin based fibre reinforced polymer-matrix composite materials (PMCs) have provided excellent solutions to many industries based on their great specific strength, high design freedom and other characteristics such as water resistance, corrosion resistance, tailorable electrical conductivity, tailorable thermal performance and many others. But, despite of all their benefits, the materials are also limited by uneconomical recycling and management post service life, demanding raw materials storage conditions, less than ideal environmental impact during manufacturing, and relatively low productivity. The purpose of the present work was to investigate economically feasible production of a continuous fibre reinforced thermoplastic composite (CFRTP) alternative solution, for an existing company, that could overcome weak points and limitations of thermosets under increasing environmental needs and pursuit of higher efficiency. Work aimed at fulfilling the following objectives: 1) document existing thermoplastic composite materials and understand selected manufacturing methods, raw materials, mechanical behaviour and operational feasibility; 2) select, design, and build a fully functional CFRTP manufacturing line; 3) design and run Taguchi methods to analyze the product using multifactorial ANOVA to gently introduce rigorous quality control; and 4) identify the input parameters that most affect output product quality, that could be used to optimize the process, as well as input parameters that have no statistically significant effects on the output and therefore do not warrant investment in funds and time in order to control them. Throughout the work, it was showed that CFRTP could been produced efficiently with consistent quality. Unidirectional prepreg can be used directly or further processed for usage in many industries such as pipelines, light construction and automotive components. The design of the CFRTP solution fulfilled necessary conditions and successfully produced CFRTP unidirectional prepreg product. Prepreg produced under 16 different sets of conditions was tested and data was collected. Using Taguchi methods, this study found that the fibre volume fraction, condition of impregnation mould, condition of cooling rollers and extruding temperature all have statistically significant effects on product quality. But limited by restriction from time and cost by production based environments, it is imperative to conduct this work perfectly, in later research a more focused study can be done based on the results of this study. Still, thesis demonstrates a CFRTP mass production solution, verifies CFRTP impregnation and offers a significant route for upgrading environmental protection and production efficiency. The work also identifies key parameters that affect unidirectional prepregs properties.

We use the Hamilton equations to describe the dynamics of a particle and present results for equatorial trajectories, obtaining an algebraic equation for the magnitude of the black hole's angular momentum. We tailor a numerical code to solve the dynamical equations and use it to generate synthetic data. We apply the method in some representative examples, obtaining the parameters of the trajectories as well as the black hole's angular momentum in good agreement with the input data.

description: We study embedding of non-commuting $Z_2$ and $Z_m$, $m\geq 3$ symmetries in discrete subgroups (DSG) of $U(3)$ and analytically work out the mixing patterns implied by the assumption that $Z_2$ and $Z_m$ describe the residual symmetries of the neutrino and the charged lepton mass matrices respectively. Both $Z_2$ and $Z_m$ are assumed to be subgroups of a larger discrete symmetry group $G_f$ possessing three dimensional faithful irreducible representation. The residual symmetries predict the magnitude of a column of the leptonic mixing matrix $U_{\rm PMNS}$ which are studied here assuming $G_f$ as the DSG of $SU(3)$ designated as type C and D and large number of DSG of $U(3)$ which are not in $SU(3)$. These include the known group series $Σ(3n^3)$, $T_n(m)$, $Δ(3n^2,m)$, $Δ(6n^2,m)$ and $Δ'(6n^2,j,k)$. It is shown that the predictions for a column of $|U_{\rm PMNS}|$ in these group series and the C and D types of groups are all contained in the predictions of the $Δ(6N^2)$ groups for some integer $N$. The $Δ(6N^2)$ groups therefore represent a sufficient set of $G_f$ to obtain predictions of the residual symmetries $Z_2$ and $Z_m$.

Scaling of tripartite entanglement at impurity quantum phase transitions

description: The emergence of a diverging length scale in many-body systems at a quantum phase transition implies that total entanglement has to reach its maximum there. In order to fully characterize this, one has to consider multipartite entanglement as, for instance, bipartite entanglement between individual particles fails to signal this effect. However, quantification of multipartite entanglement is very hard and detecting it may not be possible due to the lack of accessibility to all individual particles. For these reasons it will be more sensible to partition the system into relevant subsystems, each containing few to many spins, and study entanglement between those constituents as a coarse-grain picture of multipartite entanglement between individual particles. In impurity systems, famously exemplified by two-impurity and two-channel Kondo models, it is natural to divide the system into three parts, namely, impurities and the left and right bulks. By exploiting two tripartite entanglement measures, based on negativity, we show that at impurity quantum phase transitions the tripartite entanglement diverges and shows scaling behavior. While the critical exponents are different for each tripartite entanglement measure they both provide very similar critical exponents for the two-impurity and the two-channel Kondo models suggesting that they belong to the same universality class.

description: Many integral equations used to analyze scattering, such as the standard combined field integral equation (CFIE), are not well-conditioned for a wide range of frequencies and multi-scale geometries. There has been significant effort to alleviate this problem. A more recent one is using a set of decoupled potential integral equations (DPIE). These equations have been shown to be robust at low frequencies and immune to topology breakdown. But they mimic the ill-conditioning behavior of CFIE at high frequencies. This paper addresses this deficiency through new Calderón-type identities derived from the Vector Potential Integral Equation (VPIE). We construct novel analytic preconditioners for the vector potential integral equation (VPIE) and scalar potential integral equation (SPIE) constrained to perfect electric conductors (PEC). These new formulations are wide-band well-conditioned and converge rapidly for multi-scale geometries. This is demonstrated though a number of examples that use analytic and piecewise basis sets.

description: The emergence of cloud computing based on virtualization technologies brings huge opportunities to host virtual resource at low cost without the need of owning any infrastructure. Virtualization technologies enable users to acquire, configure and be charged on pay-per-use basis. However, Cloud data centers mostly comprise heterogeneous commodity servers hosting multiple virtual machines (VMs) with potential various specifications and fluctuating resource usages, which may cause imbalanced resource utilization within servers that may lead to performance degradation and service level agreements (SLAs) violations. To achieve efficient scheduling, these challenges should be addressed and solved by using load balancing strategies, which have been proved to be NP-hard problem. From multiple perspectives, this work identifies the challenges and analyzes existing algorithms for allocating VMs to PMs in infrastructure Clouds, especially focuses on load balancing. A detailed classification targeting load balancing algorithms for VM placement in cloud data centers is investigated and the surveyed algorithms are classified according to the classification. The goal of this paper is to provide a comprehensive and comparative understanding of existing literature and aid researchers by providing an insight for potential future enhancements.

description: The impact of BSC implementation on the organization performance is considered to be an important issue in a current business world in which organizations tries to measure their performance using different performance evaluation systems. This study empirically examines the impact of the four BSC components on performance by taking the case of Ethiopian airlines. The study attempt to highlight the impact of financial, customer, internal process, and learning and growth perspectives, through which the manager should cascaded down the organization strategy to the lower level. The study employed structured questionnaire which was administered on a sample of 336 employees of the airline to examine the impact of BSC implementation on Ethiopian airlines performance. The study used SPSS data techniques specifically linear regression for its analysis. Validity, reliability, and multicollinearity tests were conducted on the data. The data analysis made based on result conducted through correlation and linear regression. The results of linear regression analysis shows that the customer perspective (b=0.359, p < 0.01), internal process perspective (b=0.195, p < 0.01), and learning and growth perspective (b=0.259, p < 0.01) significantly influence the performance of Ethiopian airlines. But financial perspective (b=0.031, p > 0.1) is found to be not significant to influence performance of the airlines in this study. Based on the findings of the study the strength and weakness of BSC implementation in the airline are also identified. Recommendations are made based on the overall findings for possible action which will help further improvement based on the researcher view. This study shows the impact of the three BSC perspectives which significantly affect the performance of Ethiopian Airlines.

description: We proposed and demonstrated a new approach for realizing spin orbit coupling with ultracold atoms. We use orbital levels in a double well potential as pseudospin states. Two-photon Raman transitions between left and right wells induce spin-orbit coupling. This scheme does not require near resonant light, features adjustable interactions by shaping the double well potential, and does not depend on special properties of the atoms. A pseudospinor Bose-Einstein condensate spontaneously acquires an antiferromagnetic pseudospin texture which breaks the lattice symmetry similar to a supersolid.

Bifurcation analysis and steady state patterns in reaction-diffusion systems augmented with self- and cross-diffusion

description: In this article, we carry out a study of long-term behavior of reaction-diffusion systems augmented with self- and cross-diffusion, using an augmented Gray-Scott system as a general example. The methodology remains generic, and is therefore applicable to other systems. Simulations of the temporal model (nonlinear parabolic system) reveal the presence of steady states, often associated with energy dissipation. A Newton method based on a mixed finite element method is provided, in order to directly evaluate the steady states (nonlinear elliptic system) of the temporal system, and is validated against its solutions. Linear stability analysis (LSA) using Fourier analysis is carried out around homogeneous equilibria, and using spectral analysis around non-homogeneous ones. For the latter, the spectral problem is solved numerically. A multi-parameter bifurcation is reported. Original steady state patterns are unveiled, not observable with linear diffusion only. Two key observations are made: a dependency of the pattern with the initial condition of the system, and a dependency on the geometry of the domain.

description: Given the recent advances in multimodal image pretraining where visual models trained with semantically dense textual supervision tend to have better generalization capabilities than those trained using categorical attributes or through unsupervised techniques, in this work we investigate how recent CLIP model can be applied in several tasks in artwork domain. We perform exhaustive experiments on the NoisyArt dataset which is a dataset of artwork images crawled from public resources on the web. On such dataset CLIP achieves impressive results on (zero-shot) classification and promising results in both artwork-to-artwork and description-to-artwork domain.

description: Ausgangspunkt des Beitrags ist die jüngere politische Orientierung am Leitbild 'flexibler Erwerbsbürgerschaft'. Sie wird in einigen europäische Länder bereits seit längerem in Form einer aktivierenden Arbeitsmarkt- und Sozialpolitik realisiert. Für die Bundesrepublik, so die hier vertretene These, stellt die Orientierung an einer 'Beschäftigungsfähigkeit für alle' eine besondere Herausforderung dar. Denn die sozialstaatlichen Rahmenbedingungen sind auch im wiedervereinigten Deutschland nach wie vor vorrangig an der Arbeitsmarktteilhabe eines männlichen Familienernährers und weniger an der Beschäftigungsfähigkeit von Frauen bzw. von Eltern orientiert. Der Beitrag diskutiert strukturelle Rahmenbedingungen und Reformoptionen in den Bereichen Arbeitsmarkt-, Familien- und Bildungspolitik und fragt abschließend nach dem demokratischen Potential flexibler Erwerbsbürgerschaft

description: Through a very careful analysis Kolopanis and collaborators identified a negative power spectrum (PS) systematic. The 21 cm cosmology community has assumed that any observational systematics would add power, as negative PS are non-physical. In addition to the mystery of their origin, negative PS systematics raise the spectre of artificially lowering upper limits on the 21 cm PS. It appears that the source of the negative PS systematics is a subtle interaction between choices in how the PS estimate is calculated and baseline-dependent systematic power. In this paper we present a statistical model of baseline dependent systematics to explore how negative PS systematics can appear and their statistical characteristics. This leads us to recommendations on when and how to consider negative PS systematics when reporting observational 21 cm cosmology upper limits.
