Some non-existence and asymptotic existence results for weighing matrices

, 2016
Orthogonal designs and weighing matrices have many applications in areas such as coding theory, cryptography, wireless networking and communication. In this paper, we first show that if positive integer $k$ cannot be written as the sum of three integer ...

Existence and Uniqueness of Solutions to Four-Point Impulsive Fractional Differential Equations with p-Laplacian Operator

Mathematics, 2022
In this paper, by using fixed-point theorems, the existence and uniqueness of positive solutions to a class of four-point impulsive fractional differential equations with p-Laplacian operators are studied. In addition, three examples are given to justify

Existence of entire radial solutions to a class of quasilinear elliptic equations and systems

Electronic Journal of Qualitative Theory of Differential Equations, 2016
In this paper, by a monotone iterative method and the Arzèla-Ascoli theorem, we obtain the existence of entire positive radial solutions to the following quasilinear elliptic equations \[\operatorname{div}(\phi_1(|\nabla u|) \nabla u)+a_1(|x|) \phi_1 ...

Existence and Stability of Standing Pulses in Neural Networks : I Existence

, 2003
We consider the existence of standing pulse solutions of a neural network integro-differential equation. These pulses are bistable with the zero state and may be an analogue for short term memory in the brain.

Taming Existence in RDF Querying [PDF]

, 2008
We introduce the recursive, rule-based RDF query language RDFLog. RDFLog extends previous RDF query languages by arbitrary quantifier alternation: blank nodes may occur in the scope of all, some, or none of the universal variables of a rule.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Rola poznania naukowego w filozofii Karla Jaspersa (The role of the scientific world orientation in the philosophy of Karl Jaspers) [PDF]

Analiza i Egzystencja, 2012
Karl Jaspers’ doctrine was a continuation of the great tradition of Western philosophy, which sought “the being”. In his conception “the being” was conceived in three ways: as objective being (“being of things”), as subjective being (“me”) and as ...
