  • I protagonisti della grande distribuzione in Europa

    Publication

    - Year 2017

    The chapter outlines the main aspects of the history of some of the most important big European department stores (El Corte Ingles, Auchan, Carrefour, LeClerc, Aldi, Esselunga and the Finiper Group,

  • Stany nadzwyczajne i „niezwyczajne”

    Konstytucja Rzeczypospolitej Polskiej jako ustawa zasadnicza definiuje trzy stany nadzwyczajne, które mogą być wprowadzone w sytuacjach szczególnych zagrożeń, jeżeli zwykłe środki konstytucyjne są niewystarczające. Dodatkowo w systemie prawnym Rzeczypospolitej Polskiej funkcjonują stan zagrożenia epidemicznego i stan epidemii, a także stany gotowości obronnej państwa i stopnie alarmowe wprowadzane w związku z zagrożeniami o...

  • A Loophole of All ‘Loophole-Free’ Bell-Type Theorems

    Publication

    Bell’s theorem cannot be proved if complementary measurements have to be represented by random variables which cannot be added or multiplied. One such case occurs if their domains are not identical. The case more directly related to the Einstein–Rosen–Podolsky argument occurs if there exists an ‘element of reality’ but nevertheless addition of complementary results is impossible because they are represented by elements from different...

    - PHYSICAL REVIEW A - Year 2015

    Einstein-Podolsky-Rosen steering is a form of inseparability in quantum theory commonly acknowledged to be intermediate between entanglement and Bell nonlocality. However, this statement has so far only been proven for a restricted class of measurements, namely, projective measurements. Here we prove that entanglement, one-way steering, two-way steering, and nonlocality are genuinely different considering general measurements,...

  • LE STIME ECONOMICHE DELLA CIA E L’IMPREVEDIBILE FINE DELL’URSS

    Publication

    - Studi Storici - Year 2021

    In this article, we will analyze the debate that took place around the assessments that the CIA gave of the economic situation in the Soviet Union, a clearly decisive key to understanding the overall health of the main political-military opponent of the United States. The article will include the discussions that flared up in the American political establishment starting in 1990, after the fall of the Berlin Wall and the initial...

  • Modal analysis of a fish-belly flap type of steel water gate

    ABSTRACT: The results of a modal analysis of the fish-belly flap type of steel water gate are presented in the paper. The analysis was conducted for a detailed numerical model of the structure using four-node quadrilateral shell elements. The study was focused on the examination of the influence of positioning of the flap gate and hydrostatic pressure of water on the eigenvalues and eigenmodes of the structure. The results of the study...

  • Intrinsic asymmetry with respect to adversary: a new feature of Bell inequalities

    Publication

    - Journal of Physics A-Mathematical and Theoretical - Year 2014

    It is known that the local bound of a Bell inequality is sensitive to the knowledge of the external observer about the settings statistics. Here we ask how that sensitivity depends on the structure of that knowledge. It turns out that in some cases it may happen that the local bound is much more sensitive to the adversaryʼs knowledge about the settings of one party than the other. Remarkably, there are Bell inequalities which are...

  • Strong Monogamies of No-Signaling Violations for Bipartite Correlation Bell Inequalities

    Publication

    - PHYSICAL REVIEW LETTERS - Year 2014

    The phenomenon of monogamy of Bell inequality violations is interesting both from the fundamental perspective as well as in cryptographic applications such as the extraction of randomness and secret bits. In this article, we derive new and stronger monogamy relations for violations of Bell inequalities in general no-signaling theories. These relations are applicable to the class of binary output correlation inequalities known as...

  • Bell-Type Inequalities from the Perspective of Non-Newtonian Calculus

    Publication

    A class of quantum probabilities is reformulated in terms of non-Newtonian calculus and projective arithmetic. The model generalizes spin-1/2 singlet state probabilities discussed in Czachor (Acta Physica Polonica:139 70–83, 2021) to arbitrary spins s. For s → ∞ the formalism reduces to ordinary arithmetic and calculus. Accordingly, the limit “non-Newtonian to Newtonian” becomes analogous to the classical limit of a quantum theory
