  • The Łojasiewicz Exponent at Infinity of Non-negative and Non-degenerate Polynomials 

    Oleksik, Grzegorz ORCID; Różycki, Adam ORCID (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 ...
  • Using multitype branching models to analyze bacterial pathogenicity 

    Sakowski, Sebastian ORCID; Tahir, Daniah; Ingemar, Kaj; Bartoszek, Krzysztof; Majchrzak, Marta; Parniewski, Paweł (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 ...
  • Cytokine profiling in exhaled breath condensate after exercise challenge in asthmatic children with post-exercise symptoms 

    Sielski, Piotr ORCID; Majak, Paweł; Jerzyńska, Joanna; Bojo, Magdalena; Brzozowska, Agnieszka; Koczkowska, Magdalena; Stelmach, Włodzimierz; Stelmach, Rafał; Janas, Anna; Stelmach, Iwona (Termedia Publishing House, 2016)
    Introduction: Markers of exhaled breath condensate (EBC) correlate with lung function impairment, airway remodeling and different aspects of the disease such as exercise-induced bronchoconstriction (EIB). Aim of the study ...
  • Stress and Anxiety Levels in Pregnant and Post-Partum Women during the COVID-19 Pandemic 

    Horzelski, Wojciech ORCID; Stepowicz, Anna; Wencka, Barbara; Grzesiak, Mariusz; Bieńkiewicz, Jan (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 ...
  • Necessary and Sufficient Conditions for Robust Minimal Solutions in Uncertain Vector Optimization 

    Studniarski, Marcin ORCID; Stasiak, Aleksandra ORCID; Michalak, Anna ORCID (Springer Nature, 2020)
    We introduce a new notion of a vector-based robust minimal solution for a vector-valued uncertain optimization problem, which is defined by means of some open cone. We present necessary and sufficient conditions for this ...
  • On a Nonsmooth Gauss–Newton Algorithms for Solving Nonlinear Complementarity Problems 

    Śmietański, Marek ORCID (MDPI, 2020)
    In this paper, we propose a new version of the generalized damped Gauss–Newton method for solving nonlinear complementarity problems based on the transformation to the nonsmooth equation, which is equivalent to some ...
  • Multi Ping-Pong and an Entropy Estimate in Groups 

    Walczak, Paweł ORCID; Tarchała, Katarzyna (De Gruyter, 2018)
    We provide an entropy estimate from below for a finitely generated group of transformation of a compact metric space which contains a ping-pong game with several players located anywhere in the group.
  • Przyczyny i sposoby przeciwdziałania wykluczeniu cyfrowemu 

    Wojczyk, Sebastian ORCID; Lipnicka, Marta ORCID; Lipnicki, Artur ORCID (Wydawnictwo Naukowe Uniwersytetu Szczecińskiego, 2015)
    Rozwój technologii informacyjnych jest niewątpliwie jednym z najbardziej dynamicznie rozwijających się obszarów życia. W społeczeństwie powstają różnice między osobami, które posiadają dostęp do technologii informacyjnych, ...
  • Comparison of ultrasound image filtering methods by means of multivariable kurtosis 

    Zajączkowski, Paweł ORCID; Nieniewski, Mariusz ORCID (International Society for Stereology & Image Analysis, 2017)
    Comparison of the quality of despeckled US medical images is complicated because there is no image of a human body that would be free of speckles and could serve as a reference. A number of various image metrics are ...
  • On conformal submersions with geodesic or minimal fibers 

    Zawadzki, Tomasz ORCID (Springer, 2020)
    We prove that every conformal submersion from a round sphere onto an Einstein manifold with fbers being geodesics is—up to an isometry—the Hopf fbration composed with a conformal difeomorphism of the complex projective ...
  • Notes on noncommutative LP and Orlicz spaces 

    Goldstein, Stanisław ORCID; Labuschagne, Louis (Wydawnictwo Uniwersytetu Łódzkiego, 2020)
    Since the pioneering work of Dixmier and Segal in the early 50’s, the theory of noncommutative LP-spaces has grown into a very refined and important theory with wide applications. Despite this fact there is as yet no ...
  • Deterministyczne procedury obliczeniowe tomografii grawitacyjnej we współrzędnych ortogonalnych i sferycznych 

    Bednarek, Stanisław ORCID (Wydawnictwo Uniwersytetu Łódzkiego, 2020)
    W monografii przedstawiono autorskie metody obliczeń, które pozwalają na wyznaczenie gęstości mas w zadanym obszarze na podstawie pomiarów przyspieszenia siły ciężkości, wykonanych na zewnątrz tego obszaru. Szczegółowo ...
  • Gelfond-Mahler inequality for multipolynomial resultants 

    Gala-Jaskórzynska, Aleksandra; Kurdyka, Krzysztof; Rudnicka, Katarzyna; Spodzieja, Stanisław ORCID (Wydawnictwo Uniwersytetu Łódzkiego, 2019)
    We give a bound of the height of a multipolynomial resultant in terms of polynomial degrees, the resultant of which applies. Additionally we give a Gelfond-Mahler type bound of the height of homogeneous divisors of a ...
  • A family of hyperbolas associated to a triangle 

    Zięba, Maciej (Wydawnictwo Uniwersytetu Łódzkiego, 2019)
    In this note, we explore an apparently new one parameter family of conics associated to a triangle. Given a triangle we study ellipses whose one axis is parallel to one of sides of the triangle. The centers of these ellipses ...
  • Rings and fields of constants of cyclic factorizable derivations 

    Zieliński, Janusz (Wydawnictwo Uniwersytetu Łódzkiego, 2019)
    We present a survey of the research on rings of polynomial constants and fields of rational constants of cyclic factorizable derivations in polynomial rings over fields of characteristic zero.
  • A few introductory remarks on line arrangements 

    Szpond, Justyna (Wydawnictwo Uniwersytetu Łódzkiego, 2019)
    Points and lines can be regarded as the simplest geometrical objects. Incidence relations between them have been studied since ancient times. Strangely enough our knowledge of this area of mathematics is still far from ...
  • Extremal properties of line arrangements in the complex projective plane 

    Pokora, Piotr (Wydawnictwo Uniwersytetu Łódzkiego, 2019)
    In the present note we study some extreme properties of point-line configurations in the complex projective plane from a viewpoint of algebraic geometry. Using Hirzebruch-type inequalites we provide some new results on ...
  • Finitely generated subrings of R[x] 

    Nowicki, Andrzej (Wydawnictwo Uniwersytetu Łódzkiego, 2019)
    In this article all rings and algebras are commutative with identity, and we denote by R[x] the ring of polynomials over a ring R in one variable x. We describe rings R such that all subalgebras of R[x] are finitely generated ...
  • On the dual Hesse arrangement 

    Lampa-Baczyńska, Magdalena; Wójcik, Daniel (Wydawnictwo Uniwersytetu Łódzkiego, 2019)
    In the present note we investigate to which extent the configuration of 9 lines intersecting in triples in 12 points is determined by these incidences. We show that up to a projective automorphism there is exactly one such ...
  • Knots of irreducible curve singularities 

    Krasinski, Tadeusz ORCID (Wydawnictwo Uniwersytetu Łódzkiego, 2019)
    In the article the relation between irreducible curve plane singularities and knots is described. In these terms the topological classification of such singularities is given.
