Dynamique d'un nuage de bulles homogène confiné [PDF]

, 2013
De nombreuses applications industrielles mettent en jeu des écoulements à bulles dans des échangeurs de masse et de chaleur ou des réacteurs. Les mouvements des bulles génèrent de l'agitation dans le liquide qui, en retour, influence la distribution ...

Spin Calogero-Moser systems associated with simple Lie algebras

, 2000
We introduce spin Calogero-Moser systems associated with root systems of simple Lie algebras and give the associated Lax representations (with spectral parameter) and fundamental Poisson bracket relations.

A roadmap to key traits of invasive Drosophilidae

Biological Reviews, EarlyView.
ABSTRACT Biological invasions have intensified in recent decades, mostly driven by international trade and travel, raising significant concerns, particularly regarding insect pests. Once non‐native species establish, they can disrupt natural ecosystem stability, undermine agroecosystem sustainability and cause substantial economic losses.

Restricted Tweedie stochastic block models

Canadian Journal of Statistics, EarlyView.
Abstract The stochastic block model (SBM) is a widely used framework for community detection in networks, where the network structure is typically represented by an adjacency matrix. However, conventional SBMs are not directly applicable to an adjacency matrix that consists of nonnegative zero‐inflated continuous edge weights.

Modelling Tribochemical Reactions of Lubricants in the UHV Analytical Tribometer

Tribology Online, 2015
Gas Phase Lubrication (GPL) is used here to lubricate counterparts of a tribological system with a partial pressure of a gas. Because the rheological contribution (Hydrodynamic and EHL) of gas is practically negligible, the role of tribochemical ...

Plant adaptive strategies respond to environmental change across European grassland habitats

Ecography, EarlyView.
Grassland ecosystems are facing rapid and ongoing change driven by intensified land‐use and accelerated climate change, highlighting the urgent need to understand their potential adaptation and response to environmental change. We analyzed data from 52 980 vegetation plots spanning all major grassland habitats in Europe (including alpine, rocky, sandy,

Multiobjective Simulation–Optimization of Crop Allocation and Water Resources in Canal Command Areas Using Genetic Algorithms

Irrigation and Drainage, EarlyView.
ABSTRACT This study develops an integrated simulation–optimization framework for sustainable crop allocation and water resource management in the Bargarh Canal Command (BCC), eastern India. Efficient irrigation allocation remains a critical challenge due to competing demands, groundwater–surface water interactions and environmental constraints ...

A series of SNR-based speech intelligibility models in the Auditory Modeling Toolbox

Acta Acustica, 2022
This technical paper presents a series of speech intelligibility models that have been developed since the original version proposed by Lavandier and Culling [(2010). Journal of the Acoustical Society of America 127, 387–399].

Constraints on automorphism groups of higher dimensional manifolds

, 2013
In this note, we prove, for instance, that the automorphism group of a rational manifold X which is obtained from CP^k by a finite sequence of blow-ups along smooth centers of dimension at most r with k>2r+2 has finite image in GL(H^*(X,Z)).

More than proteins for empty stomachs: Wild meat in the BaTonga food system

People and Nature, EarlyView.
Abstract Our paper highlights the limitations of the framework used by many conservation‐focused programmes that incorporate food security objectives. This framework encourages the substitution of wild proteins with domestic proteins by promoting animal farming in communities located near conservation areas.
