Quel potentiel des outils génétiques pour étudier le rétablissement de la connectivité des habitats piscicoles ?

open access: yesSciences, Eaux & Territoires, 2018
Avec environ 92 000 obstacles à l'écoulement répertoriés sur le territoire français, le rétablissement de la connectivité des habitats piscicoles figure aujourd'hui parmi les principaux enjeux des politiques publiques de l'environnement. Si les priorités

Poisson deleting derivations algorithm and Poisson spectrum [PDF]

open access: yesCommunications in Algebra, 2016
In [5] Cauchon introduced the so-called deleting derivations algorithm. This algorithm was first used in noncommutative algebra to prove catenarity in generic quantum matrices, and then to show that torus-invariant primes in these algebras are generated by quantum minors. Since then this algorithm has been used in various contexts.

The gravitational self-force

open access: yes, 2004
The self-force describes the effect of a particle's own gravitational field on its motion. While the motion is geodesic in the test-mass limit, it is accelerated to first order in the particle's mass.

Conservation de la biodiversité et changement climatique : un nécessaire changement de paradigme - Le cas des poissons migrateurs amphihalins

open access: yesSciences, Eaux & Territoires, 2010
Les espèces les plus menacées font l'objet de plans de restauration visant à retrouver une situation antérieure jugée plus satisfaisante. Mais le changement climatique qui s'est opéré dans certaines régions nécessite de se poser la question de l'utilité ...

Compound Poisson Process with a Poisson Subordinator [PDF]

open access: yesJournal of Applied Probability, 2015
A compound Poisson process whose randomized time is an independent Poisson process is called a compound Poisson process with Poisson subordinator. We provide its probability distribution, which is expressed in terms of the Bell polynomials, and investigate in detail both the special cases in which the compound Poisson process has exponential jumps and ...

Description de trois espèces nouvelles de Myxosporidies (Myxozoa : Myxosporea) parasites de Citharinus citharus (Geoffroy Saint-Hilaire, 1809) (Citharinidae) au Tchad (Afrique Centrale)

open access: yesParasite, 2004
L'examen de Citharinus citharus (Geoffroy Saint-Hilaire, 1809 (Teléostéen, Citharinidae), récolté sur le fleuve Chari au Tchad, a révélé la présence de trois espèces nouvelles de Myxosporidies dont nous donnons ici la description complète : Thelohanellus

A STUDY OF SMALL AREA ESTIMATION TO MEASURE MULTIDIMENSIONAL POVERTY WITH MIXED MODEL POISSON, ZIP, AND ZINB

open access: yesBarekeng, 2023
The research began with calculating the value of multidimensional poverty at the district level in West Java Province from SUSENAS 2021. The calculation of multidimensional poverty was based on individuals in each district or city household.

Tidal deformation of a slowly rotating black hole

open access: yes, 2015
In the first part of this article I determine the geometry of a slowly rotating black hole deformed by generic tidal forces created by a remote distribution of matter.

Electroweak multi-monopoles

open access: yesNuclear Physics B, 2023
We construct the multi-charge generalizations for the electroweak magnetic monopole solution of Cho and Maison within a wide range of values of the magnetic charge. We use the same ansatz for the axially symmetric fields as the one previously employed to
