This paper studies the unified symmetry of a nonholonomic system of non-Chetaev type with unilateral constraints in event space under infinitesimal transformati
This paper reports that the ground-state energy of polaxon was obtained with strong electron-LO-phonon coupling by using a variational method of the Pekax type
Ho3+: GdVO4 is a new laser material suitable for high-power laser systems. In this paper we measure the absorption spectra of Ho3 in the sample Ho3+: GdVO4. The
油菜是我国重要的油料作物,同时也是我国唯一的冬季油料作物。每角粒数作为油菜产量构成因素之一,是典型的数量性状(表型连续分布且容易受到环境因素的影响),具有相对复杂的遗传机理。已定位的油菜每角粒数QTL很多,但对其精细定位的却很少,而克隆的报道目前只有一例。实验室前期利用在每角粒数上有较大差异的油菜测序品种中双11(de novo sequencing)和No.73290(re-sequencing
Based on a modified coupled wave theory of Kogelnik, we have studied the diffraction of an ultrashort pulsed beam with an arbitrary polarization state from a vo
In this paper an efficient quantum secure direct communication (QSDC) scheme with authentication is presented,which is based on quantum entanglement and polariz
