Transfers of small analytes in a multiphasic stirred fruit yoghurt model

2007

International audience; The transfer of small analytes in a multiphasic stirred fruit yoghurt model, made of a pectin gel aimed to mimic fruit pieces and of a dairy gel done with milk acidified by glucono-δ-lactone hydrolysis, have been studied. The concentration gradients between the pectin gel and the dairy gel were the driving force for the migration of small analytes (i.e. water, protons and colorants). Water migrated from the dairy to the pectin gel, causing modifications in the water content of both gels and an equilibration of their water activity at 0.938±0.003. Inversely, protons migrated from the pectin to the dairy gel. These changes in composition of both gels being likely to ha…

Theoretical space-time modelling of the diffusion of raw materials and manufactured objects

2013

International audience; Workgroup 3 of ArchaeDyn II programme focuses its study on the diffusion systems of ancient products. In order to be able to structure data in GIS in an appropriate way, we propose a general theoretical modelling integrating the different components of the diffusion systems, and identifying their interactions and the factors affecting the location of products and their transfers. Three dimensions are considered: the Time, the Space and the Function of places. A product's pathway can be apprehended efficiently by distinguishing spatial entities as well as functional entities. This modelling highlights the fact that the approach through the simple notion of "site" is n…

Decay estimates for time-fractional and other non-local in time subdiffusion equations in R^d

2016

We prove optimal estimates for the decay in time of solutions to a rather general class of non-local in time subdiffusion equations in R d . An important special case is the timefractional diffusion equation, which has seen much interest during the last years, mostly due to its applications in the modeling of anomalous diffusion processes. We follow three different approaches and techniques to study this particular case: (A) estimates based on the fundamental solution and Young’s inequality, (B) Fourier multiplier methods, and (C) the energy method. It turns out that the decay behaviour is markedly different from the heat equation case, in particular there occurs a critical dimension phenom…

A Performance Evaluation of Fusion Techniques for Spatio-Temporal Saliency Detection in Dynamic Scenes

2013

International audience; Visual saliency is an important research topic in computer vision applications, which helps to focus on regions of interest instead of processing the whole image. Detecting visual saliency in still images has been widely addressed in literature. However, visual saliency detection in videos is more complicated due to additional temporal information. A spatio-temporal saliency map is usually obtained by the fusion of a static saliency map and a dynamic saliency map. The way both maps are fused plays a critical role in the accuracy of the spatio-temporal saliency map. In this paper, we evaluate the performances of different fusion techniques on a large and diverse datas…

L'application sur agrément du régime fiscal des fusions aux opérations d'apport partiel d'actif (CGI, art. 210 B, 3) : critères de l'autonomie et aut…

2012

National audience; La cour administrative d'appel de Lyon rappelle que les dispositions du a du 3 de l'article 210 B du CGI ne subordonnent pas l'octroi de l'agrément à la condition que l'apport partiel d'actif porte sur une branche complète d'activité, mais exigent seulement que l'opération soit justifiée par un motif économique, se traduisant notamment par l'exercice, par la société bénéficiaire de l'apport, d'une activité autonome ou l'amélioration des structures. En l'espèce, la cour estime que l'opération était bien justifiée par un motif économique se traduisant par l'amélioration des structures, motif dont il n'appartient pas à l'Administration d'apprécier l'opportunité.

L'optimisation fusion - confusion : une synthèse privilégiée du droit et du chiffre

2010

It is not always easy to dissociate, in the settlement problems, tax and accounting, the main thing and the ac cessory. Generally, mergers are in this case, simplified mergers and universal transmissions, too. When professionals want, in this field, to optimize integrated, legal choices - tax - accounting, it is often obliged to treat the problem, without assistanc e. This autonomy look that this subject is at the crossroads of several disciplines and it is necessary to compose, without really opposing them. The field of mergers and confusion is a good synthesis of the link Law - management. The company which wishes to absorb its 100 % subsidiary can choose between simplified fusion and dis…

Solar neutrino physics with Borexino

2018

We present the most recent solar neutrino results from the Borexino experiment at the Gran Sasso underground laboratory. In particular, refined measurements of all neutrinos produced in the {\it pp} fusion chain have been made. It is the first time that the same detector measures the entire range of solar neutrinos at once. These new data weakly favor a high-metallicity Sun. Prospects for measuring CNO solar neutrinos are also discussed.

Towards saturation of the electron-capture delayed fission probability : The new isotopes 240Es and 236Bk

2017

The new neutron-deficient nuclei 240Es and 236Bk were synthesised at the gas-filled recoil separator RITU. They were identified by their radioactive decay chains starting from 240Es produced in the fusion–evaporation reaction 209Bi(34S,3n)240Es. Half-lives of 6(2) sand 22+13−6swere obtained for 240Es and 236Bk, respectively. Two groups of αparticles with energies Eα=8.19(3) MeVand 8.09(3) MeVwere unambiguously assigned to 240Es. Electron-capture delayed fission branches with probabilities of 0.16(6)and 0.04(2)were measured for 240Es and 236Bk, respectively. These new data show a continuation of the exponential increase of ECDF probabilities in more neutron-deficient isotopes. peerReviewed
