Group cohomology with coefficients in a crossed module

, 2010
We compare three different ways of defining group cohomology with coefficients in a crossed module: (1) explicit approach via cocycles; (2) geometric approach via gerbes; (3) group theoretic approach via butterflies. We discuss the case where the crossed

A structural equation modeling of English tests’ social and educational consequences: exploring target, leverage, risk, and critical variables

Language Testing in Asia, 2022
Though the emergence of standardized testing promoted classical approaches such as summative achievement tests, it brought about serious criticisms regarding the stakes of these tests and their consequences on different dimensions of education. Exploring

Universal enveloping crossed module of Leibniz crossed modules and representations

Journal of Physics: Conference Series, 2016
The universal enveloping algebra functor UL: Lb → Alg, defined by Loday and Pirashvili [1], is extended to crossed modules. Then we construct an isomorphism between the category of representations of a Leibniz crossed module and the category of left modules over its universal enveloping crossed module of algebras.

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 ...

New Braided T-Categories over Weak Crossed Hopf Group Coalgebras

Abstract and Applied Analysis, 2013
Let H be a weak crossed Hopf group coalgebra over group π; we first introduce a kind of new α-Yetter-Drinfel’d module categories 𝒲𝒴𝒟α(H) for α∈π and use it to construct a braided T-category 𝒲𝒴𝒟(H).

HMM-based Offline Recognition of Handwritten Words Crossed Out with Different Kinds of Strokes [PDF]

, 2008
In this work, we investigate the recognition of words that have been crossed-out by the writers and are thus degraded. The degradation consists of one or more ink strokes that span the whole word length and simulate the signs that writers use to cross ...

Solid Pseudopapillary Neoplasm of the Pancreas in Children and Adolescents: Expert Recommendations

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Solid pseudopapillary neoplasm of the pancreas (SPN) is a rare low‐grade malignant exocrine pancreatic tumor, mostly discovered during the second decade of life in females, with a very good prognosis, provided microscopically complete surgical excision is achieved.

Higher-form symmetries and 3-group in axion electrodynamics

Physics Letters B, 2020
We study higher-form symmetries in a low-energy effective theory of a massless axion coupled with a photon in (3+1) dimensions. It is shown that the higher-form symmetries of this system are accompanied by a semistrict 3-group (2-crossed module ...

Cross-Modulation Interference With Lateralization of Mixed-Modulated Waveforms [PDF]

Journal of Speech, Language, and Hearing Research, 2010
Purpose This study investigated the ability to use spatial information in mixed-modulated (MM) sounds containing concurrent frequency-modulated (FM) and amplitude-modulated (AM) sounds by exploring patterns of interference when different modulation types originated from different loci as may occur in a multisource acoustic ...

The precise center of a crossed module [PDF]

The final publication is available at www.degruyter.com[EN] We generalize the definition of the precise center of a group to the crossed modules context. We construct the Ganea map for the homology of crossed modules, and we study the connections between
