Properties of solutions of a bistable nonlinear convolution equation in higher space dimensions are studied. The nonlinearity is the derivative of a double well function. The theory of traveling waves for this equation was given in a previous publication 4]. Here we consider spreading phenomena for state regions, in some cases by means of the motion of domain walls, which are modeled by interna...

Unequal propagation of central venous excess pressure into the different cerebral and spinal venous drainage systems is the rule rather than the exception. The intensity of the forces thus to be exerted on vulnerable cerebrospinal structures by the resulting pressure-gradients in the craniovertebral space is unknown. There is a need to consider the various conditions which may cause individual ...

In this paper we consider some finite generalized polygons, defined over a field with characteristic 2, that admit an embedding in a projective or affine space over a field with characteristic unequal to 2. In particular, we classify the (lax) embeddings of the unique generalized quadrangle H(3, 4) of order (4, 2). We also classify all (lax) embeddings of both the split Cayley hexagon H(2) and ...

It is well known that the normal mixture with unequal variance has unbounded likelihood and thus the corresponding global maximum likelihood estimator (MLE) is undefined. One of the commonly used solutions is to put a constraint on the parameter space so that the likelihood is bounded and then one can run the EM algorithm on this constrained parameter space to find the constrained global MLE. H...

Given that macrophages can proliferate and that certain microbes survive inside phagocytic cells, the question arises as to the post-mitotic distribution of microbial cargo. Using macrophage-like cells we evaluated the post-mitotic distribution of intracellular Cryptococcus yeasts and polystyrene beads by comparing experimental data to a stochastic model. For beads, the post-mitotic distributio...

Although the bequest motive is one of the most important theoretical extensions of the life-cycle hypothesis, few empirical studies have measured determinants of unequal estate division. We estimated whether several proxies that are consistent with exchange and altruism lead to unequal estate division using data from a longitudinal survey of deceased elderly persons linked to probate court reco...

In this paper, we present a new structure for linear−phase filter banks without redundancy, which have unequal−length filters at each subband. First, we extend the simplified lattice structure of the linear−phase filter bank to the unequal−length linear−phase paraunitary filter bank. In general, the unequal−length linear−phase paraunitary filter bank has equal−length filters at both the analysi...

The Cal Poly ITRC irrigation evaluation programs have been widely used to assess the global distribution uniformity (DU) of drip and microsprayer irrigation systems. The field procedures and formulas used in the program are presented in this paper. The system DU is estimated by mathematically combining the component DU values. DU components include pressure differences, "other causes" (such as ...
