Acute generalized exanthematous pustulosis associated with spider bite [PDF]
Anais Brasileiros de Dermatologia, 2016 : Acute generalized exanthematous pustulosis (AGEP) is an acute febrile rash, usually induced by drugs, which recently has been linked to spider bite. We report a case of a male patient, 48 years old, with an erythematous rash accompanied by fever and ...

Vector Subdivision Schemes for Arbitrary Matrix Masks [PDF]
Journal of Computational and Applied Mathematics, Vol. 437 (2024),
115478, 2022 Employing a matrix mask, a vector subdivision scheme is a fast iterative averaging algorithm to compute refinable vector functions for wavelet methods in numerical PDEs and to produce smooth curves in CAGD. In sharp contrast to the well-studied scalar subdivision schemes, vector subdivision schemes are much less well understood, e.g., Lagrange and ...

Tick mitochondrial genomes: structural characteristics and phylogenetic implications
Parasites & Vectors, 2019 Ticks are obligate blood-sucking arachnid ectoparasites from the order Acarina, and many are notorious as vectors of a wide variety of zoonotic pathogens. However, the systematics of ticks in several genera is still controversial.

Arthropod borne diseases in Italy: from a neglected matter to an emerging health problem
Annali dell'Istituto Superiore di Sanità , 2010 In medical entomology, "Arthropod Borne Diseases", or "Vector Borne Diseases" (VBD) are intended as a group of human and animal infections caused by different pathogen organisms (protozoa, helminthes, bacteria and viruses) transmitted by the bite of a ...

Vector inflation by kinetic coupled gravity [PDF]
IJMPD, Volume 23, Issue 8, id. 1450069 (2014), 2014 Vector inflation is a newly established model where inflation is driven by non-minimally coupled massive vector fields with a potential term. This model is similar to the model of chaotic inflation with scalar fields, except that for vector fields the isotropy of expansion is achieved either by considering a triplet of orthogonal vector fields or $N ...

A graph discretization of vector Laplace operator [PDF]
arXiv, 2023 In this paper, we study the graph-theoretic analogues of vector Laplacian (or Helmholtz operator) and vector Laplace equation. We determine the graph matrix representation of vector Laplacian and obtain the dimension of solution space of vector Laplace equation on graphs.

Journal of Physics A: Mathematical and General, 38, (7), 1577-1592
(2005), 2004 We give a constructive and exhaustive definition of Kochen-Specker (KS) vectors in a Hilbert space of any dimension as well as of all the remaining vectors of the space. KS vectors are elements of any set of orthonormal states, i.e., vectors in n-dim Hilbert space, H^n, n>3 to which it is impossible to assign 1s and 0s in such a way that no two ...

Vector and axial vector mesons at finite temperature [PDF]
Eur.Phys.J.C25:445-452,2002, 2002 We consider the thermal correlation functions of vector and axial-vector currents and evaluate corrections to the vector and axial-vector meson pole terms to one loop in chiral perturbation theory. As expected, the pole positions do not shift to leading order in temperature. But the residues decrease with temperature.

Non-singular Cooperative Guiding Vector Field Under a Homotopy Equivalence Transformation [PDF]
arXiv, 2023 The present article advances the concept of a non-singular cooperative guiding vector field under a homotopy equivalence transformation. Firstly, the derivation of a guiding vector field, based on a non-singular vector field, is elaborated to navigate a transformed path from another frame. The existence of such vector fields is also deliberated herein.
