Проблемы научного управления социалистическим обществом

1978

В статьях сборника приводятся результаты обсуждений вопросов научного управления социалистическим обществом: метод планирования путем разработки целевых комплексных программ, опыт разработки социального планирования, опыт создания системы автоматизированных банков данных республиканской автоматизированной системы. В области совершенствования информации, которая является центральной категорией управления, проводится идея ликвидации элементов стихийности, разобщенности, несовместимости, плюрализма информационных языков и создания их совместимости, интеграции и единства с естественным языком.

In Silico Conformational Features of Botulinum Toxins A1 and E1 According to Intraluminal Acidification

2022

International audience; Although botulinum neurotoxins (BoNTs) are among the most toxic compounds found in nature, their molecular mechanism of action is far from being elucidated. A key event is the conformational transition due to acidification of the interior of synaptic vesicles, leading to translocation of the BoNT catalytic domain into the neuronal cytosol. To investigate these conformational variations, homology modeling and atomistic simulations are combined to explore the internal dynamics of the sub-types BoNT/A1 (the most-used sub-type in medical applications) and BoNT/E1 (the most kinetically efficient sub-type). This first simulation study of di-chain BoNTs in closed and open s…

Bringing Building Data on Construction Site for Virtual Renovation Works

2013

Déjà sur HAL mais sans le fichier pdf; In this study we aimed at evaluating the benefit of managing a digital mock-up for renovation operations in an ancient building. Focusing on thermal efficiency, the renovation proposal dealt with the great windows. We compared three methodologies dedicated to the project planning and management We first address the issue of the renovation of old buildings and come up with a workflow that connects the digital building to its lifecycle; then we focus on an instance of onsite handling of such data, in an augmented reality context, by elaborating the notion of “BIM in situ” as described in the papers of [3] as well as in [4]. Results reveal that handling B…

Quantification of atelectatic lung volumes in two different porcine models of ARDS.

2006

BACKGROUND: Cyclic recruitment during mechanical ventilation contributes to ventilator associated lung injury. Two different pathomechanisms in acute respiratory distress syndrome (ARDS) are currently discussed: alveolar collapse vs persistent flooding of small airways and alveoli. We compare two different ARDS animal models by computed tomography (CT) to describe different recruitment and derecruitment mechanisms at different airway pressures: (i) lavage-ARDS, favouring alveolar collapse by surfactant depletion; and (ii) oleic acid ARDS, favouring alveolar flooding by capillary leakage. METHODS: In 12 pigs [25 (1) kg], ARDS was randomly induced, either by saline lung lavage or oleic acid (…

Abel transforms with low regularity with applications to X-ray tomography on spherically symmetric manifolds

2017

We study ray transforms on spherically symmetric manifolds with a piecewise $C^{1,1}$ metric. Assuming the Herglotz condition, the X-ray transform is injective on the space of $L^2$ functions on such manifolds. We also prove injectivity results for broken ray transforms (with and without periodicity) on such manifolds with a $C^{1,1}$ metric. To make these problems tractable in low regularity, we introduce and study a class of generalized Abel transforms and study their properties. This low regularity setting is relevant for geophysical applications.

Automorphisms of hyperelliptic GAG-codes

2009

Abstract We determine the n –automorphism group of generalized algebraic-geometry codes associated with rational, elliptic and hyperelliptic function fields. Such group is, up to isomorphism, a subgroup of the automorphism group of the underlying function field.
