Degree of the divisor of solutions of a differential equation on a projective variety [PDF]

open access: yes, 1999
Using the data schemes developed by Arrondo-Sols-Speiser, we give a rigorous definition of algebraic differential equations on the complex projective space $P^n$.

Tunneling, self-trapping and manipulation of higher modes of a BEC in a double well [PDF]

open access: yes, 2013
We consider an atomic Bose-Einstein condensate trapped in a symmetric one-dimensional double well potential in the four-mode approximation and show that the semiclassical dynamics of the two ground state modes can be strongly influenced by a macroscopic ...

Science Said. Relationships between Science, Reason and Faith

open access: yesScientia et Fides, 2013
After a description of the method of mathematics and empirical sciences, brief but explicit enough to show their limits with philosophical and theological reflection, I comment the harmonic relations of mutual help among them, and also, unfortunately ...

Potassium limitation of forest productivity – Part 2: CASTANEA-MAESPA-K shows a reduction in photosynthesis rather than a stoichiometric limitation of tissue formation [PDF]

open access: yesBiogeosciences, 2023
Potassium (K) availability constrains forest productivity. Brazilian eucalypt plantations are a good example of the K limitation of wood production. Here, we built upon a previously described model (CASTANEA-MAESPA-K) and used it to understand whether ...

Synthesis of zirconia colloidal dispersions by forced hydrolysis [PDF]

open access: yesJournal of the Serbian Chemical Society, 2006
Different zirconia colloidal dispersions (sols) were prepared from zirconyl oxynitrate and zirconyl oxychloride solutions by forced hydrolysis. Vigorously stirred acidic solutions of these salts were refluxed at 102 oC for 24 h.

Actin reorganization at the centrosomal area and the immune synapse regulates polarized secretory traffic of multivesicular bodies in T lymphocytes

open access: yesJournal of Extracellular Vesicles, 2020
T-cell receptor stimulation induces the convergence of multivesicular bodies towards the microtubule-organizing centre (MTOC) and the polarization of the MTOC to the immune synapse (IS). These events lead to exosome secretion at the IS.
