The 4-fold completive self-sorting of a ten-component library (7 dissimilar donors and 3 different acceptors) resulted in the clean self-assembly of four dynamic orthogonal complexes although ≥143 combinations are conceivable. Due to the non-interference of the complexes, each ligand of the four combinations was embedded to one side of the quadrilateral to serve as a linkage at one metal corner...

A double-dwell acquisition system that can simultaneously operate search and verification processes, by employing two correlation blocks, is proposed. The search block continuously looks for threshold-crossing instants, and at those instants, the verification block is reset and reinitiated. The threshold is time varying and updated depending on the partial correlation. Computer simulation resul...

Trace Recalling is a novel method for deconvoluting double traces that result from simultaneously sequencing two DNA templates. Trace Recalling identifies up to two bases at each position of such a trace. The resulting ambiguity sequence is aligned to the genome, identifying one template sequence. A second template sequence is then inferred from this alignment. This technique makes possible man...

In this paper, by use of affine biquadratic elements, we construct and analyze a finite volume element scheme for elliptic equations on quadrilateral meshes. The scheme is shown to be of second-order in H-norm, provided that each quadrilateral in partition is almost a parallelogram. Numerical experiments are presented to confirm the usefulness and efficiency of the method. Mathematics Subject C...

Abstract : Accuracy of a simulation is strongly depend on the grid quality. Here, quality means orthogonality at the boundaries and quasi-orthogonality within the critical regions, smoothness, bounded aspect ratios, solution adaptive behaviour, etc. We review various functionals for generating high quality structured quadrilateral meshes in two dimensional domains. Analysis of Winslow and Modif...

This paper develops a computational model for nonlinear bending analysis of functionally graded (FG) plates using a four-node quadrilateral element SQ4T within the context of the first order shear deformation theory (FSDT). In particular, the construction of the nonlinear geometric equations are based on Total Lagrangian approach in which the motion at the present state compared with the initia...

Recent work [Ecoscience (2000) vol. 7, 395-397] suggests that the burying beetle Nicrophorus pustulatus may have undergone a remarkable host shift, exploiting snake eggs rather than carrion as resources for breeding. We conducted behavioural and physiological experiments to examine the hypothesis of a host shift and to formulate hypotheses on its origin. Two congeners of N. pustulatus, Nicropho...

The myocardial effect of snake venoms is considered as one of the most common pathogenesis in many cases of snake envenomation. This study was under taken to investigate the effects of snake (Naja naja oxiana) venom on cardiac function in experimental animals. The blood samples from all the rabbits were collected before venom injection and then 140 µg/kg venom of snake (Naja naja oxiana) was in...
