The Hilbert scheme of $n$ points in a smooth del Pezzo surface $S$ parameterizes zero-dimensional subschemes with length $n$ on $S$. We construct a flat family of deformations of Hilb$^n S$ which can be conceptually ...

Having explicitly calculated universal deformations, the next logical question is whether we can calculate deformations with local restrictions. In fact, the ordinary deformation problem is representable, and we explain ...

Degenerate geometric data (e.g., three points on a line, four points on a circle) is known to create all sorts of special cases, some easy and some complicated, that have to be considered in implementations of geometric ...

For ultrathin oxides, a new type of failure mode, soft breakdown, has been observed. The characteristics of this kind of failure are often identified by a large increase of gate signal noise level. It has been proposed ...

Aspartate transcarbamylase (ATCase) is degraded upon starvation of Bacillus subtilis cells for carbon or nitrogen. The rate of ATCase degradation in exponentially growing B. subtilis cells was determined by measurement of ...

A computer-based Monte Carlo simulation of incoherent plural scattering of electrons has been developed in order to estimate the broadening of an electron probe as it propagates through a solid. By applying this approach ...

Manure degradation and ammonia desorption rates from under-floor pits in swine buildings were investigated in this research. Manure degradation was experimentally determined under simulated pit operational conditions (1.8% ...

Prevotella ruminicola 23 and Prevotella bryantii B14 are obligate anaerobic bacteria in the Bacteroidetes phylum that contribute to hemicellulose utilization within the bovine rumen. These bacteria efficiently degrade the ...

We examine several problems in extremal graph theory, emphasizing problems involving games on graphs. In Chapter 2, we study a variant of Ramsey theory, seeking Ramsey hosts with small maximum degree. We focus on finding ...

Consider the second order non-linear differential operator ${\cal L}y$ = Ly + $\eta y\sp3$, where $\eta$ = $\pm$1 and L, the linear part of ${\cal L}$, is of the form Ly = $y\sp{\prime\prime}$ + $p(x)y\sp\prime$ + q(x)y. ...
