Assessing the movement of magnetotactic bacteria(MTB)under magnetic fields is a key to exploring the function of the magnetotaxis.In this study,a simple method was used to analyze the behavior of MTB,which was based o...

The present paper deals with a tectonic event of Late Ordovician age affecting three blocks of China,i.e.South China,North China and Tarim.In the North China and the Tarim platforms,as well as their marginal belts,the...
With the summarization of the Early Paleozoic paleomagnetic data recently obtained from the three major blocks of China, the Early Paleozoic (i.e. Cambrian and Ordovician) paleogeographic positions of the North China,...
The model about block extrusion related to collision between Eurasia and India which is proposed by Tapponnier et al. has not been accepted so far in the field. Based on kinematics and chronology, the Gailigong dextra...

We only discuss finite undirected simple graph.Suppose graph G is connected. If for each pair of vertices x and y of G there is the unique shortest path which connects x and y, then G is called geodetic graph. If G is...
K. R. Parthasarathy and N. Srinivasan have proposed the problem of how to construct a geodetic block with given diameter and given girth, that is, to construct a 2-connected graph G with given diameter d and given gir...
G is a finite group, F is a splitting field of G with characteristic p. FG is the group algebra. We denote FG by R. Let J(R) be the radical of R. For a subalgebra W of R, let (?)=(W+J(R))/J(R), and it is a subalgebra ...
Ⅰ. INTRODUCTION If there are s factors of which each factor has q levels in an experiment, where q>1, then the orthogonal array is often used. The number of experiments is 0(q^2) which is too large when q is comparat...
It seems more reasonable to rename the so-called plates as fault-blocks because their developments are controlled by world-wide fracture-systems and defined by various types of faults. The main arguments are briefly s...
