We study double structures on the projective line and on certain other varieties, with a view to having a nice family of degenerations of curves and K3 surfaces of given genus and Cli ord index. Our main interest is in the canonical embeddings of these objects, with a view toward Green's Conjecture on the free resolutions of canonical curves. We give the canonical embeddings explicitly, and exh...

We develop a new method to obtain stochastic characterizations of Yang–Mills elds. Our main tool is the Itô-equation for the stochastic parallel transport. We estimate the drift terms in a small ball of radius and nd that for a general connection the average rotation is of order 3 but that for a Yang–Mills connections the average rotation is of order . Using a Doob h-transform we give a new pro...

Th e fi ft y years since the 100th anniversary of John Dewey’s birth have marked the emergence of new technologies that aff ord a wealth of previously unknown approaches to learning, making it not only possible but practicable for Dewey’s educational vision of participatory learning to be realized on a mass scale. Th is chapter discusses these possibilities and their implications for learning i...

Contemporary optical fibers can deal with almost all of the unfavorable effects which are known these days. They have sufficiently low specific slump, they can handle a slump caused by OHions, they can restrain the multimode effect and finally they can compensate a chromatic dispersion. But there is one problem, which the present science can’t solve and this problem is the Polarization Mode Dis...

It is generally accepted that regional labor markets are characterized by strong interdependencies. However, only few studies include spatial elements to their estimations. Using the model framework proposed by Cliff and Ord (1973, 1981) and the estimation technique proposed by Kelejian and Prucha (1998), we estimate a spatial time series model for the Swiss cantonal unemployment rates on a qua...

In the first paper of this series (1) a model for microheterogeneity of plasma albumins was presented together with some critical evidence in support of its adoption. According to this model plasma albumin consists of a very large number of similar molecular species. The N-F transition of the protein as observed by electrophoresis, solubility, optical rotatory dispersion, and other methods is a...

We demonstrate continuously tunable optical delays as large as 1.1 micros range for 10 Gb/s NRZ optical signals based on four-wave mixing (FWM) process in silicon waveguide. The large delay range is made possible by a novel wavelength-optimized optical phase conjugation scheme, which allows for tunable dispersion compensation to minimize the residual group-velocity dispersion (GVD) for the enti...
