Many operations within a solid modeling application, notably applying thickness (shelling) or blending edges ( lleting), encounter di culties during topology resolution. In order to create a solid object, certain faces have to be intersected but the geometry is such that no intersection curve can be computed. The solution is to "extend" one or both faces. This means that one has to extrapolate ...

Let I ⊂ K[x1, . . . , xn] be a zero-dimensional monomial ideal, and ∆(I) be the simplicial complex whose Stanley–Reisner ideal is the polarization of I. It follows from a result of Soleyman Jahan that ∆(I) is shellable. We give a new short proof of this fact by providing an explicit shelling. Moreover, we show that ∆(I) is even vertex decomposable. The ideal L(I), which is defined to be the Sta...

A new simple method for synthesis of core/shell CdSe/ZnS nanocrystals (NCs) is present. By adapting the use of cadmium stearate, oleylamine, and paraffin liquid to a non-injection synthesis and by applying a subsequent ZnS shelling procedure to CdSe NCs cores using Zinc acetate dihydrate and sulfur powder, luminescent CdSe/ZnS NCs with quantum yields of up to 36% (FWHM 42-43 nm) were obtained. ...

The 2{weak vertex-packing polytope of a loopless graph G with d vertices is the subset of the unit d{cube satisfying x i + x j 1 for every edge (i; j) of G. The dilation by 2 of this polytope is a polytope P with integral vertices. We triangulate P with lattice simplices of minimal volume and label the maximal simplices with elements of the hyperoctahedral group B d. This labeling gives rise to...

(Shelling, 2000). Of interest is the lower copy number detection rate in our study (4%) compared with the detection rate of 48% in the recent publication by Quilter et al. (2010). Quilter et al. report that one of the 15 women with a CNV had primary amenorrhea. Possibilities to explain the differences in detection rate compared with this study may be differences in the age of onset of POF, or t...

Peanuts receive major emphasis because of the crop's importance to the economy of southeastern Virginia and the magnitude of pesticide use in crop management. In 1992, growers planted 93,000 acres of the crop and harvested an estimated 123,225 tons of peanuts with a value of ca. 79 million dollars in farm income. When coupled with the shelling, processing and shipping industries in the Tidewate...

Two parallel-plate electrodes were mounted inside a cylinder, made of a non-conducting material. The space between the plates was filled with peanut pods and the capacitance and phase angle of this system was measured with a prototype low-cost impedance meter, designed for this purpose. Measurements were made at frequencies of 1 and 5 MHz on peanut pod (in-shell) samples of known moisture conte...
