The Israeli Occupation tends from the first moment of occupying Palestinian lands to seize and loot all the natural wealth and resources depriving the Palestinians of exploitation them and sovereignty on them by its executive, legislative and military policies despite INALIENABLE RIGHT in the rules of international law and the resolutions United Nations that caused severe effects and damages on the Palestinians. After the General Assembly of the United Nations recognition of the state of occupied Palestine on 29/11/2012 and becoming an observer member state which is considered as a very important step to put The State of Palestine in the frame of international law which enables it to join international entities that are under the United Nation system; joining Rome Statute of the International Criminal Court; It opens the way for the prosecution of the Israeli occupation for its multiple crimes such seizing and wasting the Palestinian natural wealth and to demand compensation for the full damage caused to wealth, the loss of profit and income on the Palestinian state; They are the axes that the research aims to shed light on.

This chapter chronicles the populist candidate’s rise to power, which follows a pattern resembling exponential growth: it starts slowly and grows steadily until it reaches an inflection point that marks an unstoppable moment. The term tsunami describes the first moment in the dynamic theory of populism in power, when insurgent populist candidates are able to tap into the existing mass dissatisfaction with political institutions and take advantage of growing elite disarray. As they become significant contenders, their momentum increases; seen as potential winners by others, they generate bandwagon effects and fascinate the media. These aspiring populist leaders expand their appeal through different ways. Some politicians associated with the old order bet on them and offer their support. Populist candidates expand the electorate by politically activating new actors or social forces, or by mobilizing previously apathetic voters.

Machine learning methods have garnered much attention and use in computational catalysis. Previous studies have demonstrated rapid and accurate prediction of a variety of catalytic properties as well as the underlying potential energy landscapes. In particular, d-band center, defined as the first moment of the d-projected density of states, has been widely used as the key descriptor of activity trends for reactions catalyzed by metal surfaces. In this work, we construct a gradient boosting regression (GBR) model for prediction of the d-band center of bulk binary transition metal alloys. An accurate model is obtained using a dataset of over 1200 alloys from the Materials Project database spanning the entire d-block of the periodic table. The d-band centers, periodic groups, and relative compositions of the constituent metals are determined to have the highest feature importance scores, consistent with the underlying physics of the alloy. The regression model presented here offer a promising strategy of rapid property prediction with physical interpretability to aid the optimization and discovery of efficient heterogeneous catalysts.

We derive explicit asymptotic confidence intervals for any Markov chain Monte Carlo (MCMC) algorithm with finite asymptotic variance, started at any initial state, without requiring a Central Limit Theorem nor reversibility nor geometric ergodicity nor any bias bound. We also derive explicit non-asymptotic confidence intervals assuming bounds on the bias or first moment, or alternatively that the chain starts in stationarity. We relate those non-asymptotic bounds to properties of MCMC bias, and show that polynomially ergodicity implies certain bias bounds. We also apply our results to several numerical examples. It is our hope that these results will provide simple and useful tools for estimating errors of MCMC algorithms when CLTs are not available.

We present a new strategy to identify mixed infections and minority variants in Mycobacterium tuberculosis by whole-genome sequencing. The objective of the strategy is the direct detection in patient sputum; in this way, minority populations of resistant strains can be identified at the time of diagnosis, facilitating identification of the most appropriate treatment for the patient from the first moment.

In the framework of continuous improvement of university education, the corresponding bodies are attentive to the good practices detached by the agents that comprise them. In this study, gamification in the mathematics learning process is described from the perspective of 286 students identified by non-probabilistic intentional sampling. Under these arguments, the methodology of the study is non-experimental, descriptive ex-post-facto level; the data for the analysis were collected in two stages: first moment in an instantaneous way to be able to perceive directly the gamification in the learning of mathematics through the Mentimenter tool; in second moment, the questionnaire was applied with 33 items composed of three dimensions: dynamics, mechanics and component from the contributions of Kevin Werbach. The results attributed to the study show that gamification, from the student's perspective, is a dynamic tool for the learning of previous concepts of Basic Mathematics and Mathematical Complements in the first academic semesters; in addition, the teacher plays the role of facilitator and the student responsibly manages his space and learning environment.

AbstractWhile driving, dangerous situations can occur quickly, and giving drivers extra time to respond may make the road safer for everyone. Extensive research on attentional cueing in cognitive psychology has shown that targets are detected faster when preceded by a spatially valid cue, and slower when preceded by an invalid cue. However, it is unknown how these standard laboratory-based cueing effects may translate to dynamic, real-world situations like driving, where potential targets (i.e., hazardous events) are inherently more complex and variable. Observers in our study were required to correctly localize hazards in dynamic road scenes across three cue conditions (temporal, spatiotemporal valid and spatiotemporal invalid), and a no-cue baseline. All cues were presented at the first moment the hazardous situation began. Both types of valid cues reduced reaction time (by 58 and 60 ms, respectively, with no significant difference between them, a larger effect than in many classic studies). In addition, observers’ ability to accurately localize hazards dropped 11% in the spatiotemporal invalid condition, a result with dangerous implications on the road. This work demonstrates that, in spite of this added complexity, classic cueing effects persist—and may even be enhanced—for the detection of real-world hazards, and that valid cues have the potential to benefit drivers on the road.

The article discusses the application of a rapid action electrical fuse with controllable overload current in the schemes of industrial and household electrical equipment. There has been found a deficiency in the basic version of the scheme. A variant of the circuit was proposed, which helps to get rid of the drawback in the basic version: if a condenser with relatively large capacity (C ≥ 100 μF) is present in the protected circuit (in the load circuit), the circuit may not reach the operating mode, because, when the condenser is on, its large charging current triggers the electronic fuse and the load remains unconnected. This situation can be avoided only if the charging current of the condenser is greatly reduced, for which a current source on a field-effect transistor VT3 and a timing circuit R10R11C1 were introduced into the circuit. As C1 is being charged, through the current source VT3 there is a smooth increase in the bias voltage at the emitter junctions of the composite transistor switch VT1VT2 with a gradual increase in its conductivity. As a result, the starting current through the capacitive load at the first moment of time turns out to be much less, and the electronic fuse enters the operating mode. The optimal relationships were found between individual elements of the circuit, their values and modes of operation, depending on the size and nature of the load, while, thanks to the use of the domestic element base, the cost of the device turned out to be minimal compared to other circuits of a similar type. The research data can be used for operation of the devices of a similar type in the household and for industrial applications.

The paper discusses the continuous-time Markov Branching Process allowing Immigration. We are considering a critical case for which the second moment of offspring law and the first moment of immigration law are possibly infinite. Assuming that the nonlinear parts of the appropriate generating functions are regularly varying in the sense of Karamata, we prove theorems on convergence of transition functions of the process to invariant measures. We deduce the speed rate of these convergence providing that slowly varying factors are with remainder

O argumento do presente texto defende que o “Novo Brutalismo”, sendo indiscutivelmente um debate arquitetónico de origem britânica, era movido por um princípio universal: a adesão intelectual aos problemas do seu tempo. A luta contra o academicismo e o historicismo, a aceitação da realidade e das diferentes formas de cada cultura construir o seu habitat, e a crescente importância atribuída aos utilizadores da arquitetura, constituem pontos essenciais para a revisão dos modelos arquitetónicos levada a cabo no pós-guerra. Estes princípios despertam o interesse de uma nova geração de arquitetos portugueses cada vez mais crítica e atenta ao debate internacional, que os assimila por coincidência de interesses, mais do que por conexão ou influência direta. A metodologia adotada passa por recuperar alguns argumentos dos textos de 1955 e de 1966 do crítico Reyner Banham, o principal ideólogo do Novo Brutalismo, com particular incidência nas propostas dos arquitetos Alison e Peter Smithson e o seu papel no grupo Team 10. Após se introduzirem as origens e o contexto do debate, esboça-se o panorama da situação portuguesa nesses anos, com especial incidência na difusão da “novíssima” geração de arquitetos (sensivelmente, os nascidos entre finais de 1920 e inícios de 1930) por iniciativa da revista Arquitectura. Finalmente, apresentam-se os argumentos de dois representantes dessa geração —Nuno Portas e Pedro Vieira de Almeida— cuja relação com o brutalismo não reside em questões estéticas, de forma ou de tratamento das superfícies, mas sim em questões éticas, ou seja, de compromisso com a “utilidade social da arquitetura”. Num primeiro momento, expõe-se um debate em torno à habitação coletiva centrado em métodos e posições críticas, que se complementa num segundo momento com uma breve abordagem a uma obra de arquitetura na qual ambos têm responsabilidade. The argument of the present text argues that the "New Brutalism", being arguably an architectural debate of British origin, was driven by a universal principle: the intellectual adherence to the problems of its time. The struggle against academicism and historicism, the acceptance of reality and the different ways each culture builds its habitat, and the growing importance given to the users of architecture, are essential points for the post-war revision of architectural models. These principles have awakened the interest of a new generation of Portuguese architects that is increasingly critical and attentive to the international debate, assimilating them through coincidence of interests, rather than through direct connection or influence. The methodology adopted involves recovering some arguments from the 1955 and 1966 texts of the critic Reyner Banham, the main ideologue of New Brutalism, with particular focus on the proposals of the architects Alison and Peter Smithson and their role in the Team 10 group. After introducing the origins and context of the debate, the panorama of the Portuguese situation in those years is outlined, with special focus on the diffusion of the "brand new" generation of architects (roughly those born between the late 1920s and early 1930s) through the initiative of the magazine Arquitectura. Finally, we present the arguments of two representatives of this generation -Nuno Portas and Pedro Vieira de Almeida- whose relationship with brutalism does not lie in aesthetic questions, of form or surface treatment, but in ethical questions, i.e., their commitment to the "social utility of architecture. In a first moment, a debate around collective housing centered on methods and critical positions is exposed, which is complemented in a second moment with a brief approach to a work of architecture in which both have responsibility.
