Quantum Sufficiency in the Operator Algebra Framework
Łuczak, Andrzej
(Springer, 2013-08-01)
The paper is devoted to the investigation of the notion of sufficiency in quantum statistics. Three kinds of this notion are considered: plain sufficiency (called simply: sufficiency), Petz’s sufficiency, and Umegaki’s ... -
Stability of Nonlinear Dirichlet BVPs Governed by Fractional Laplacian
Bors, Dorota (Hindawi Publishing Corporation, 2014-03-02)
We consider a class of partial differential equations with the fractional Laplacian and the homogeneous Dirichlet boundary data. Some sufficient condition under which the solutions of the equations considered depend ... -
State Determination and Sufficiency of Observables
(Springer, 2013-05-19)Informational completeness and the possibility of state distinction and determination are among the more important issues of quantum statistics. We use spectral and semispectral (POV) measures to analyse these questions. ... -
Stress and Anxiety Levels in Pregnant and Post-Partum Women during the COVID-19 Pandemic
(MDPI, 2020)The aim of this study was to analyze stress and anxiety levels experienced by pregnant and post-partum women during the COVID-19 pandemic, as well as to indicate the social and medical factors that could contribute to ... -
Sufficient optimality criteria and duality for multiobjective variational control problems with G-type I objective and constraint functions
(Springer, 2014-06-05)In the paper, we introduce the concepts of G-type I and generalized G-type I functions for a new class of nonconvex multiobjective variational control problems. For such nonconvex vector optimization problems, we prove ... -
The Łojasiewicz Exponent at Infinity of Non-negative and Non-degenerate Polynomials
(Springer Nature, 2018)Let f be a real polynomial, non-negative at infinity with non-compact zero-set. Suppose that f is non-degenerate in the Kushnirenko sense at infinity. In this paper we give a formula for the Łojasiewicz exponent at infinity ... -
The Łojasiewicz exponent over a field of arbitrary characteristic
Brzostowski, Szymon; (Springer Verlag, 2015-01-13)
Let K be an algebraically closed field and let K((XQ)) denote the field of generalized series with coefficients in K. We propose definitions of the local Łojasiewicz exponent of F = ( f1, . . . , fm) ∈ K[[X, Y ]]m as ... -
Using multitype branching models to analyze bacterial pathogenicity
(Polskie Towarzystwo Matematyczne, 2020)We apply multitype, continuous time, Markov branching models to study pathogenicity in E. coli, a bacterium belonging to the genus Escherichia. First, we examine briefly, the properties of multitype branching processes and ... -
Variational Methods for a Fractional Dirichlet Problem Involving Jumarie’s Derivative
(Hindawi Publishing Corporation, 2015-07-08)We investigate a fractional Dirichlet problem involving Jumarie’s derivative. Using some variational methods a theorem on the existence and uniqueness of a solution to such problem is proved. In the proof of the main ... -
Zastosowanie Klasycznego Algorytmu Genetycznego do rozwiązania Zbilansowanego Zagadnienia Transportowego
(Wydział Zarządzania i Administracji UJK Kielce, 2012)Artykuł zawiera podstawowy opis algorytmów genetycznych oraz ich zasadę działania. W dalszej części definiowane jest zagadnienie transportowe, oraz sposób jego rozwiązania metodami analitycznymi. W ostatniej części ... -
Zastosowanie sieci neuronowych do planowania i analizy kampanii reklamowej
(Wydział Zarządzania i Administracji, Uniwersytet Jana Kochanowskiego w Kielcach, 2014-01-22)Artykuł ten ma na celu zaprezentowanie nowatorskiego podejścia do zarządzania i planowania w kampaniach reklamowych. Została w nim zaprezentowana metoda sieci neuronowych, które ostatnio stają się bardzo modnym ...
