The articles of Latvian and foreign researchers published in this issue represent various branches of humanities and social sciences. Researchers have used various research methods to help understand the research potential of scientific atheism and Soviet spirituality phenomena and their versatility and multi-layered nature.
Renormalized solutions on quasi open sets with nonhomogeneous boundary values

Quantum aspects originated by Gravitation: from cosmology to astrophysics
2018
El estudio de campos cuánticos que se propagan en espacio-tiempos clásicos, curvos y dinámicos, ofrece una primera manera de evaluar las consecuencias de la teoría cuántica cuando los fenómenos gravitatorios no son despreciables. Esta es una cuestión importante que debe ser abordada cuando un campo gravitatorio intenso juega un papel principal en la dinámica de un sistema físico, tal como ocurre durante el universo temprano (inflación cósmica) o en la formación de agujeros negros astrofísicos. Una de las características más sorprendentes de esta materia es quizás el hecho de que el cálculo de observables físicos, incluso para campos sin interacción, frecuentemente involucra operadores cuadr…
On Wilson’s Renormalization Group Structure
2012
Very simple remarks on the elementary mathematical structure of pQFT Wilson’s Renormalization Group are made in the light of the theory of Ehresmann’s groupoids and their possible extensions.
The Joint Distribution Criterion and the Distance Tests for Selective Probabilistic Causality
2010
A general definition and a criterion (a necessary and sufficient condition) are formulated for an arbitrary set of external factors to selectively influence a corresponding set of random entities (generalized random variables, with values in arbitrary observation spaces), jointly distributed at every treatment (a set of factor values containing precisely one value of each factor). The random entities are selectively influenced by the corresponding factors if and only if the following condition, called the joint distribution criterion, is satisfied : there is a jointly distributed set of random entities, one entity for every value of every factor, such that every subset of this set that corr…
A Shape-based Statistical Method to Retrieve 2D TRUS-MR Slice Correspondence for Prostate Biopsy
2012
International audience; This paper presents a method based on shape-context and statistical measures to match interventional 2D Trans Rectal Ultrasound (TRUS) slice during prostate biopsy to a 2D Magnetic Resonance (MR) slice of a pre-acquired prostate volume. Accurate biopsy tissue sampling requires translation of the MR slice information on the TRUS guided biopsy slice. However, this translation or fusion requires the knowledge of the spatial position of the TRUS slice and this is only possible with the use of an electro-magnetic (EM) tracker attached to the TRUS probe. Since, the use of EM tracker is not common in clinical practice and 3D TRUS is not used during biopsy, we propose to per…
Sleep Disturbances in COPD are Associated with Heterogeneity of Airway Obstruction
2018
Individuals with Chronic Obstructive Pulmonary Disease (COPD) experience sleep disturbances due to the impact of respiratory symptoms on sleep quality. We explored whether sleep disturbances in COPD are linked to heterogeneity of airway constriction.The impact of breathing problems on sleep quality was measured in consecutive COPD outpatients with the COPD and Asthma Sleep Impact Scale (CASIS) questionnaire. Impulse oscillometry technique (IOS) was employed to assess heterogeneity of airway constriction. Subjects with a previous or concomitant diagnosis of asthma or obstructive sleep apnea (OSA) were excluded.Fifty COPD subjects (M/F 40/10; age: 71 +/- 8 yrs, Body Mass Index (BMI): 26.2 +/-…
L'exclusion par l'injure à la fin du Moyen Age
2005
International audience; L'injure révèle les liens entre la vie quotidienne et les principales normes juridiques, judiciaires, morales, religieuses et politiques d'une époque. Dans les accusations qu'elle contient, l'injure renvoie aux principes moraux et aux interdits. En publiant le crime, la tare, la honte et en en faisant l'objet de la censure collective, elle vise à provoquer la marginalisation, la relégation ou l'élimination de la personne concernée, par la ruine de la fama publica, seule garantie de son intégration sociale. Le large vocabulaire qu'elle emploie révèle les prétextes de l'exclusion. Cependant l'article envisage aussi l'injure en sa qualité d'expression d'une forme de soc…
Entre socioterminologie et ethnoterminologie de l'entreprise
2016
The analysis of the designations of the commercial jobs reveals an important terminological vagueness between specialty language and common language, a vagueness conveyed by the multiplicity of the sources and of the concerned medias. Based on this observation, we propose a socioterminological and ethnoterminological study aiming at referencing the current terminological units in the speech of the company as well as of the employees. The international group Michelin, the subject of the study, presents a very rich terminological group but especially a terminology motivated by a particular historical and cultural context. Then the company becomes a model of thought and the analysis is an atte…
Broglie and Young, visionaries who shed light in the polar topology that grounds our reality: a hypothesis
2020
Una observación matemática que relaciona los patrones fractales y la operación de convolución en el contexto del procesamiento de imágenes digitales interrumpió una investigación que nos lleva a plantear la hipótesis de que el concepto de onda de materia (o dualidad onda-partícula) se encuentra en la dicotomía entre el par débil y un topología fuerte en el ámbito del marco de atractores singulares continuos en ninguna parte diferenciables y el concepto de fotón-solitón de Vigier. Tal inferencia parece ser más evidente en la interpretación de Broglie-Bohm de la mecánica cuántica en el cruce de características locales x globales. De esto se deduce también que la relación de los fenómenos natu…
