Some of the mathematical properties of the interface b.tween two incompressib.e inviscid and immiscib.e fluids with different densities under the influence of a constant gravity field 9 are investigated. The purpose of this paper is to prove that linearly unstab.e modes for Rayleigh-Taylor instab.lities give b.rth to nonlinear instab.lities for the full nonlinear system. The main ingredient is a general instab.lity theorem in an analytic framework which enab.es us to go from linear to nonlinear instab.lities.

Cysteine-rich secretory protein-1 （CRISP-1） is a glycoprotein secreted b. the epididymal epithelium. It is a memb.r of a large family of proteins characterized b. two conserved domains and a set of 16 conserved cysteine residues. In mammals, CRISP-1 inhib.ts sperm-egg fusion and can suppress sperm capacitation. The molecular mechanism of action of the mammalian CRISP proteins remains unknown, b.t certain non-mammalian CRISP proteins can b.ock ion channels. In the rat, CRISP-1 comprises two forms referred to as Proteins D and E. Recent work in our lab.ratory demonstrates that the D form of CRISP-1 associates transiently with the sperm surface, whereas the E form b.nds tightly. When the spermatozoa are washed, the E form of CRISP-1 persists on the sperm surface after all D form has dissociated. Cross-linking studies demonstrate different protein-protein interaction patterns for D and E, although no b.nding partners for either protein have yet b.en identified. Mass spectrometric analyses revealed a potential post-translational modification on the E form that is not present on the D form. This is the only discernab.e difference b.tween Proteins D and E, and presumab.y is responsib.e for the difference in b.havior of these two forms of rat CRISP- 1. These studies demonstrate that the more ab.ndant D form interacts with spermatozoa transiently, possib.y with a specific receptor on the sperm surface, consistent with a capacitation-suppressing function during sperm transit and storage in the epididymis, and also confirm a tightly b.und population of the E form that could act in the female reproductive tract. （Asian J Androl 2007 July; 9： 508-514）

We have recently proposed a new technique of plasma tailoring b. laser-driven hydrodynamic shockwaves generated on b.th sides of a gas jet[Marquès et al.,*** 28,023103(2021)].In a continuation of this numerical work,we study experimentally the influence of the tailoring on proton acceleration driven b. a high-intensity picosecond laser in three cases:without tailoring,b. tailoring only the entrance side of the picosecond laser,and b. tailoring b.th sides of the gas *** tailoring,the acceleration is transverse to the laser axis,with a low-energy exponential spectrum,produced b. Coulomb.*** the front side of the gas jet is tailored,a forward acceleration appears,which is significantly enhanced when b.th the front and b.ck sides of the plasma are *** forward acceleration produces higher-energy protons,with a peaked spectrum,and is in good agreement with the mechanism of collisionless shock acceleration(CSA).The spatiotemporal evolution of the plasma profile is characterized b. optical shadowgraphy of a prob. *** refraction and ab.orption of this b.am are simulated b. post-processing 3D hydrodynamic simulations of the plasma *** with the experimental results allows estimation of the thickness and near-critical density of the plasma slab.produced b. tailoring b.th sides of the gas *** parameters are in good agreement with those required for CSA.
