Seismic imaging of sandbox experiments – laboratory hardware setup and first reflection seismic sections
Simulated sandbox sandbox models simulation technology seismic physical model the earthquake the piezoelectric sensors seismic imaging
2015/1/5
With the study and technical development introduced here, we combine analogue sandbox simulation techniques with seismic physical modelling of sandbox models. For that purpose, we designed and develop...
Effects of Xylanase Supplementation on Growth Performance, Nutrient Digestibility and Non-starch Polysaccharide Degradation in Different Sections of the Gastrointestinal Tract of Broilers Fed Wheat-based Diets
Xylanase Broiler Performance Digestibility Non-starch Polysaccharide Degradation
2016/5/16
This experiment was performed to investigate the effects of exogenous xylanase supplementation on performance, nutrient digestibility and the degradation of non-starch polysaccharides (NSP) in differe...
On a canonical class of Green currents for the unit sections of abelian schemes
unit sections of abelian schemes canonical class of Green currents Algebraic Geometry
2011/9/22
Abstract: We show that on any abelian scheme over a complex quasi-projective smooth variety, there is a Green current for the zero-section, which is axiomatically determined up to $\partial$ and $\bar...
Creation of Homoclinic Tangencies in Hamiltonians by the Suspension of Poincaré Sections
Hamiltonian vector field Anosov flow elliptic point homoclinic tangency
2011/9/16
Abstract: In this note we show that for any Hamiltonian defined on a symplectic 4-manifold M and any point p in M, there exists a C2-close Hamiltonian whose regular energy surface through p is either ...
Opportunities to constrain astrophysical reaction rates for the s-process through determination of the ground state cross sections
nuclear reactions nucleosynthesis abundances
2011/7/21
Modern models of s-process nucleosynthesis in stars require stellar reaction rates with high precision. Most of the neutron capture cross sections in the s-process have been measured and for an increa...
n-Nilpotent Obstructions to pi_1 Sections of P^1-{0,1,infty} and Massey Products
Massey products Group/Galois cohomology Section conjecture Lower central series
2011/8/31
Abstract: Let pi be a pro-l completion of a free group, and let G be a profinite group acting continuously on pi. First suppose the action is given by a character. Then the boundary maps delta_n: H^1(...
Equidistribution of zeros of holomorphic sections in the non compact setting
holomorphic sections the non compact setting N-tensor powers non-compact complex manifold X
2011/7/28
Abstract: We consider N-tensor powers of a positive Hermitian line bundle L over a non-compact complex manifold X. In the compact case, B. Shiffman and S. Zelditch proved that the zeros of random sect...

Quivers of sections toric Deligne-Mumford stacks
2011/1/21
Starting from a collection of line bundles on a smooth projective toric DM stack,we give a stacky analogue of the classical linear series construction. We apply our construction to recover the finite ...

Sections hyperplanes à singularités exemples de variations de structure de Hodge
2011/1/20
We construct smooth complex projective varieties of dimension 3 to 6 with variations of Hodge structure, by generalizing an example of J. Carlson and C. Simpson in dimension 2. Then, we study some of ...
Hyperplane sections and the subtlety of the Lefschetz properties
Monomial ideal lifting Lefschetz properties hyperplane section
2011/1/21
The weak and strong Lefschetz properties are two basic properties that Artinian algebrasmay have. Both Lefschetz properties may vary under small perturbations or changes of the characteristic.
