基于TMS320LF2407A的32位除法算法研究

由于TMS320LF2407A数字信号处理器芯片的定点特性,没有提供除法运算指令,而实际工程中无法避免除法运算需求。根据移位指令和减法指令,本文提出了32位除法的算法原理,并给出了该原理的流程图,然后通过实验证明,该算法是正确的和有效的。

A posteriori error analysis of nonconforming methods for the eigenvalue problem

This paper extends the unifying theory for a posteriori error analysis of the nonconforming finite element methods to the second order elliptic eigenvalue problem. In particular, the author proposes the a posteriori error estimator for nonconforming methods of the eigenvalue problems and prove its reliability and efficiency based on two assumptions concerning both the weak continuity and the weak orthogonality of the nonconforming finite element spaces, respectively. In addition, the author examines these two assumptions for those nonconforming methods checked in literature for the Laplace, Stokes, and the linear elasticity problems.     

Genetic study on the behavior of honeybees influenced by polyandry system

Within a honeybee population, due to polyandry, there are supersister and halfsister relations, thus many subfamilies exist. For the Chinese honeybee (Apis cerana cerana F.) a phylogenetic dendrogram has been constructed in which 4 subfamilies are clustered based on DNA fingerprint patterns. And it has been observed that each kind of workers is distributed to several dierent sub-families.

Differential binding of conA and WGA on the cell surface,the role of sialic acid in their expression and the increased activity of sialidase after cis-Platin treatment

Summary It is reported that concanavalin A (conA) and wheat germ agglutinin (WGA) have a differential binding pattern on normal mouse spleen lymphocytes and the surface of Dalton's lymphoma cells. It is suggested that sialic acid on the cell surface controls the expression of lectin binding sites. Further, it has been observed that the increased release of sialic acid from cell surfaces aftercis-dichlorodiammine platinum (II) (cis-Platin) treatment is due to the increased activity of sialidase.To whom reprint requests should be addressed.
