This paper considers the problem of constructing a smooth surface to fit rows of data points. A special class of T-spline surfaces is examined, which is characterized to have a global knot vector in one parameter direction and individual knot vectors from row to row in the other parameter direction. These T-spline surfaces are suitable for lofted surface interpolation or approximation. A skinni...

In this paper we find, for any arbitrary finite topological type, a compact Riemann surface M, an open domain M ⊂ M with the fixed topological type, and a conformal complete minimal immersion X : M → R3 which can be extended to a continuous map X : M → R3, such that X|∂M is an embedding and the Hausdorff dimension of X(∂M) is 1. We also prove that complete minimal surfaces are dense in the spac...

The giant neurons R3-14 in the parietovisceral ganglion of Aplysia, originally proposed to be a homogeneous group of neuroendocrine cells, are likely candidates for a multifunctional and multiple messenger status. The studies reported here suggest that individual R3-14 giant neurons not only innervate specific target tissues but appear to operate more autonomously than previously thought. Ident...

Acylsugars are synthesized in the glandular trichomes of the Solanaceae family and are implicated in protection against abiotic and biotic stress. Acylsugars are composed of either sucrose or glucose esterified with varying numbers of acyl chains of differing length. In tomato (Solanum lycopersicum), acylsugar assembly requires four acylsugar acyltransferases (ASATs) of the BAHD superfamily. To...

Molecular genetic analysis and insect bioassay of transgenic indica rice 'Zhuxian B' plants carrying snowdrop lectin gene (gna) and soybean trypsin inhibitor gene (sbti) were investigated in detail. PCR, 'dot' blot and PCR-Southern blot analysis showed that both transgenes had been incorporated into the rice genome and transmitted up to R3 progeny in most lines tested. Some transgenic lines exh...

The standard contact structure ξ0 on 3-space R3 = {(x, y, z)} is the plane field on R3 given by the kernel of the 1-form dz−ydx. A Legendrian knot K in the contact manifold (R3, ξ0) is a knot which is everywhere tangent to the contact structure ξ0. The Thurston-Bennequin invariant tb(K) of a Legendrian knot K in (R3, ξ0) is the linking number of K and a knot K ′ which is obtained by moving K sl...

In this paper, we report for the first time the results of an investigation on the association of signal transducer and activator of transcription 6 (STAT6) with asthma in the Indian population. A novel polymorphic CA-repeat in the proximal promoter region [R1] and a previously identified CA-repeat in the 5'-untranslated region [R3] were genotyped, and haplotypes [R1_R3] were generated using PH...
