We experimentally explore the underlying pseudoclassical phase space structure of the quantum -kicked accelerator. This was achieved by exposing a Bose-Einstein condensate to the spatially corrugated potential created by pulses of an off-resonant standing light wave. For the first time quantum accelerator modes were realized in such a system. By utilizing the narrow momentum distribution of the...

the processing methods of kaolin are based on its high a b i l i t y of water absorption and converting easily to fine perticles of kaolin dispersed in water. so, depending on the dimension of impurities of kaolin, one can choose the pr6pe1: classifier f o r removal of them. sometimes, the texture of kaolin is not suitable for water absorption and resultant dispersion. in this case,the ore shou...

A search for pair production of dark matter candidates and supersymmetry (SUSY) production with two jets in vector-boson fusion (VBF) topology is presented using data collected by the Compact Muon Solenoid (CMS) detector in proton-proton collisions at the Large Hadron Collider (LHC). Final states with no leptons are expected in pair production of dark matter particles or scalar quarks in SUSY c...

Cantonese is rich in sentence-final particles (SFPs), morphemes serving to show various linguistic or attitudinal meanings. The acoustic manifestations of these SFPs are not yet clear. This paper presents detailed analyses of the fundamental frequency tracings, final F0, final velocity and duration of ten SFPs in Hong Kong Cantonese. The results show that most of these SFPs are very similar to ...

Rotavirus assembly is a multistep process that requires the successive association of four major structural proteins in three concentric layers. It has been assumed until now that VP4, the most external viral protein that forms the spikes of mature virions, associates with double-layer particles within the endoplasmic reticulum (ER) in conjunction with VP7 and with the help of a nonstructural p...

Formation and stability of emulsions is one of the important topics in the field of colloids and interfacial science. Surfactants and colloidal particles are often used to stabilize emulsions. Surfactants are amphiphilic molecules; they minimize the energy required for the emulsion formation by reducing oil-water interfacial tension. Colloidal particles are not amphiphilic, but partially wettab...
