The concept of the waveguide invariant is revisited and a simple relationship between the range of source and the quasi-period of the acoustic interference spectrum in the frequency domain （Ω-interference spectrum） is derived. Then a method for a broadband source ranging in shallow water using a single receiver and a broadband guide source, requiring no modeling and no knowledge about the ocean environment, is proposed. The method is validated by simulation and verified with the experimental data.

Tungsten is one of the promising candidates for the divertor plate in International Thermonuclear ExperimentalReactor (ITER) because of its high melting temperature, high thermal conductivity and low sputtering *** the operation of ITER, it will be exposed to high energy particles: hydrogen, helium and neutron, producinghigh density of interstitials and vacancies which will change the structure and properties of materials. The formationof defects changes the local stress/strain field, and the external stress/strain field will also affect the properties ofdefects. In this work, we use the Large-scale Atomic/Molecular Massively Parallel Simulator LAMMPS[1] to studythe formation of defects under strain field in tungsten.

When an energetic particle interacts with a lattice atom, different processes would be initiated sequentially intime (up to 10?12 10?11 s)[1]. Except the mobile process of defects in the last step, the others are largely ***, the formation and stability of defects produced by irradiation in metals depends on various parameters. Theeffect of temperature has been studied for years, especially by computers simulations for displacement cascade. Thehigher temperature is, the less stable Frenkel pairs (interstitial - vacancy) are left[2]. In addition to temperature,the strain or stress field would also be contributed to the formation of defects, since the formation energy is affectedby these fields. In this report, we firstly present the results of strain field effect on formation of different defectsand critical displacement energy. The discussion is then given in the end.

We investigate the interaction between self-interstitial atoms(SIAs) and 1/2 self-interstitial dislocation loops in tungsten(W) via atomistic simulations. We explore the variation of the anisotropic distribution of binding energies with the shapes and sizes of the 1/2[111] loop and the nonequivalent configurations of SIAs. For an arbitrarily shaped loop, SIA can be more easily trapped in the concave region of the loop than the convex region, which forms a loop whose curvature is closer to that of a circular loop. The direction of SIAs can largely affect the interaction behaviors with the loop. The capture distance of an SIA by the edge of a circular-shaped 1/2[111] loop is clearly elongated along the direction of the SIA;however, it weakly depends on the size of the loop. Then, we analyze the slanted ring-like capture volume of SIAs formed by the circular loop based on their generated anisotropic stress fields. Furthermore, the binding energies obtained from the elastic theory and atomistic simulations are compared. The results provide a reasonable interpretation of the growth mechanism of the loop and the anisotropic interaction that induces irregular-shaped capture volume, affording an insight into the numerical and Object Kinetic Monte Carlo simulations to evaluate the long-term and large-scale microstructural evolution and mechanical properties of W.

The effects of the dust size distribution in ultracold quantum dusty plasmas are investigated. The amplitude φm and width ω of quantum dust acoustic waves are studied with different dust size distributions in the system. The φm and ω of the quantum dust acoustic waves are found to increase as the total number density increases. The φm and ω are greater for unusual dusty plasmas than for typical dusty plasmas. Moreover, as the Fermi temperature of the dust grains increases, the φm of the wave decreases. The ω of quantum dust acoustic waves increases as the speed u0 of the wave increases

All eukaryotic cells share a common core pentasaccharide, Man3GlcNAc2 （M3）, which is found in both dolichol-linked oligosaccharides （DLOs） and N-linked glycoproteins. A pentasaccharide M3 can be elongated and elaborated by various glycosyltransferases and is thus considered as the key intermediate in the in vitro synthetic pathway of N-glycans. In this review, we describe the progresses in the preparation of M3 by chemical and chemoenzymatic methods. We first draw a brief schematic view of the typical N-glycan biological pathway and then focus on the requirements and challenges in obtaining core pentasaccharides. Representative methods and recent reported findings, especially research progress in chemoenzymatic synthesis, are highlighted. In addition, the opportunities in exploiting novel methods for constructing N-glycans, as well as their applications, are discussed.
