A coupled air-ice-ocean theoretical model for the marginal ice zone (MIZ) is developed and used to show that an off-ice and divergent wind field not only produces a dilation of the MIZ (as is generall...
Trajectories of 37 isopycnal RAFOS floats launched in the Gulf Stream off Cape Hatteras have been analyzed to examine the dynamics of meanders from a Lagrangian viewpoint. Using the float data in conj...
Horizontal divergence and vertical velocity in the surface mixed layer of the equatorial Pacific between 90° and 150°W are estimated from current measurements obtained from trajectories of freely drif...
To study horizontal divergence, the thin jet model is applied to meanders of a continuous potential vorticity front in a 11/2-layer (divergent barotropic) model. The distributions of the depth of the ...
Sperm morphology can be highly variable among species, but less is known about patterns of population differentiation within species. Most studies of sperm morphometric variation are done in species...
Small-scale internal waves are numerically ray-traced through random 3D Garrett and Munk internal wave backgrounds. Past ray-tracing investigations of the transfer of internal wave energy toward small...
Three results dealing with probability distributions (p,q) over a two-element set are presented. The two first give bounds for the entropy function H(p,q) and are referred to as the logarithmic and th...
A non-parametric symmetric measure of divergence which belongs to the family of Csiszár's f-divergences is proposed. Its properties are studied and bounds in terms of some well known divergence measur...
Domestic buffalo and cattle are two extremely important livestock species in worldwide agricultural production. In this paper, to investigate genetic diversity and divergence among swamp buffalo, rive...
摘要 In this paper we completely solve the problem on the determination of the signof divergence of a quadratic system at critical points.
摘要白腹锦鸡Chrysolophus amherstiae (Leadbeater)和红腹锦鸡Chrysolophus pictus (L.)是两个种还是两个亚种尚有争议。测定了白腹锦鸡C.amherstiae两个个体部分细胞色素b基因序列,得到完全相同的861bp的序列。与红腹锦鸡C.pictus的同源序列相比,在21个位点上出现变异,应用木村资生的双参数法算出两者的遗传距离为2.5%。根据鸡形...
The order of weighted sum of noise sequence for stochasticsystem is estimated by using limit theory in probability. Then thedivergence rates of state of unstable AR system driven by noise ofmartingale...
