A limited-area spatio-temporal stochastic pattern generator for simulation of uncertainties in ensemble applications

open access: yesMeteorologische Zeitschrift, 2017
A generator of spatio-temporal pseudo-random Gaussian fields that satisfy the “proportionality of scales” property (Tsyroulnikov, 2001) is presented.

Graph-Based Classification of Self-Dual Additive Codes over Finite Fields

open access: yes, 2008
Quantum stabilizer states over GF(m) can be represented as self-dual additive codes over GF(m^2). These codes can be represented as weighted graphs, and orbits of graphs under the generalized local complementation operation correspond to equivalence ...

On Generalized Addition Chains

open access: yes, 2014
Given integers d >= 1, and g >= 2, a g-addition chain for d is a sequence of integers a_0=1, a_1, a_2,..., a_{r-1}, a_r=d where a_i=a_{j_1}+a_{j_2}+...+a_{j_k}, with 2 =< k =< g, and 0 =< j_1 =< j_2 =< ... =< j_k =< i-1. The length of a g-addition chain is r, the number of terms following 1 in the sequence. We denote by l_g(d)

(F2 + uF2)(F4 + uF4)-Additive Cyclic Codes

open access: yesIEEE Access, 2022
In this paper, we study some structural properties of $(\mathbb {F}_{2}+u\mathbb {F}_{2})(\mathbb {F}_{4}+u\mathbb {F}_{4})$ -additive cyclic codes, including the generator polynomials, the minimum generating sets and their dual codes.

On Modularity, Indistinguishability and Generalized Metrics: Duality and Aggregation

open access: yesMathematics
In this paper, we prove that, on the one hand, a duality relationship between different types of modular T-transitive relations and the reciprocal modular generalized metrics exists and, on the other hand, that, based on this duality, a construction of ...

The tilting-cotilting correspondence

open access: yes, 2019
To a big n-tilting object in a complete, cocomplete abelian category A with an injective cogenerator we assign a big n-cotilting object in a complete, cocomplete abelian category B with a projective generator, and vice versa.

Additive Deformations of Braided Hopf Algebras

open access: yes, 2011
Additive deformations of bialgebras in the sense of J. Wirth, i.e. deformations of the multiplication map fulfilling a certain compatibility condition w.r.t. the coalgebra structure, can be generalized to braided bialgebras.

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

open access: yesPediatric 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 ...

On Fuzzy Strong $\mathrm{\phi-b-}$Normed Spaces and Fuzzy Strong $\mathrm{\phi-b-}$Normed Algebras [PDF]

open access: yesSahand Communications in Mathematical Analysis
‎Given a continuous Archimedean t-norm and its corresponding continuous additive generator, we introduce a new approach to generate a fuzzy strong $\phi-b-$norm (FS$-\phi-b-$N).
