In quantum scattering, second variational calculation is an attractive method for getting high-order approximation and controlling the increase of computational time. It is a method by combining two variational functi...
Ⅰ. INTRODUCTION In many areas, e. g. in the study of the absorption material and mammalian muscle, it is of great theoretical and practical importance to study the sound propagation in fibrous system. In this paper, ...
If X has the exponential distribution, we write X~E(λ), where λ>0 is a parameter. Due to its importance in statistics, various multivariate extensions of the exponential distribution have been given. In this letter...
I. INTRODUCTION The dyadic Green’s function (DGF) is a powerful and important means in electromagnetic theory. It was shown that an additional term must be added to the conventional electric DGF (?)_e expanded in ter...
Based on previous studies on muscovite, an approach is carried on by the authors to the features of muscovite in the Sanlitong NNE dynamo-metamorphic belt in Lujiang within the Taneheng-Lujiang fracture zone.
Suppose that X is a Banach space, S is the unit sphere of X, then for any point x0 ∈ S supporting functional exists, Chen Daoqi has given a sufficient condition of uniqueness for the supporting functional and
