M. Stachowicz, K. Granat, D. Nowak. Wroclaw University of Technology, Wroclav, Poland The subjec t-matter of the paper c overs a v ery topical problem of possible r estriction of shor tcomings like poor knocking-out properties of castings and hard reclaimability of this type sandmixes by proper selecting their components and using innovative microwave heating. It was proved that the sandmixes s...

The ganglion cell output of the retina constitutes a bottleneck in sensory processing in that ganglion cells must encode multiple stimulus parameters in their responses. Here we investigate encoding strategies of On-Off directionally selective retinal ganglion cells (On-Off DS RGCs) in rabbits, a class of cells dedicated to representing motion. The exquisite axial discrimination of these cells ...

Motivated by the work of Tilman (Ecology 75 (1994) 2) and May and Nowak (J. Theoret. Biol. 170 (1994) 95) we consider a process in which points are inserted randomly into the unit interval and a new point kills each point to its left independently and with probability a. Intuitively this dynamic will create a negative dependence between the number of points in adjacent intervals. However, we sh...

After the seminal work of Nowak and May (1992), the Spatial Prisoner’s Dilemma has become a common metaphor for studying the dynamics of cooperation in a spatially structured population. In contrast to the widely employed evolutionary model, which studies the dynamics of cooperation in a population of primitive players that lack memory, this paper examines the problem of cooperation in a popula...

The neutron index of refraction is generally derived theoretically in the Fermi approximation. However, the Fermi approximation neglects the effects of the binding of the nuclei of a material as well as multiple scattering. Calculations by Nowak introduced correction terms to the neutron index of refraction that are quadratic in the scattering length and of order 10(-3) fm for hydrogen and deut...
