density functional theory ,(dft) calculations have been performed to investigate the properties ofcarbon decorated (c-decorated) models of boron nitride (bn) nanocones. to this aim, the apex andtip of nanocone have been substituted by the carbon atoms to represent the c-decorated models. theresults indicated that dipole moments and energy gaps could reveal the effects of c-decorations onthe pro...
Described is the ICAP/3090 (for loosely coupled array of processors) parallel processing system. General parallel processing performance issues that determine the success of all multiple-instruction/multiple-datastream parallel computing systems are examined in the context of largescale scientific and engineering problems. Experiments with previous ICAP parallel processing systems that have mad...
We characterize the dependence on doublets of the cohomology of an arbitrary nilpotent differential s (including BRST differentials and classical linearized Slavnov-Taylor (ST) operators) in terms of the cohomology of the doublets-independent component of s. All cohomologies are computed in the space of local integrated formal power series. We drop the usual assumption that the counting operato...
The workspace of a spatial 6‐DOF electro‐ hydraulic parallel manipulator is strongly coupled, due to its multi‐closed‐loop kinematic structure and the coupling complicates motion planning and control of the parallel manipulator. This paper clearly analyses the strong dynamic coupling property in the workspace of a spatial 6‐DOF parallel manipulator, using modal decouplin...
Direct detection experiments rule out fermion dark matter that is a chiral representation of the electroweak gauge group. Non-chiral real, complex and singlet representations, however, provide viable fermion dark matter candidates. Although any one of these candidates will be virtually impossible to detect at the LHC, it is shown that they may be detected at future planned direct detection expe...
We compute the energy spectrum of charged leptons in the decay H+ → b̄ + (t → blνl). The shape of the lepton spectrum obtained, and also the mean lepton energy, are sensitive to the handedness of the intermediate top quark. This sensitivity can be used to precisely determine tan β, a fundamental parameter of two Higgs doublet models. PACS numbers: 14.80.Gt, 12.15.Cc Address after July 1st, 1994:...
Per the fluctuation-dissipation theorem, the information obtained from spin fluctuation studies in thermal equilibrium is necessarily constrained by the system's linear response functions. However, by including weak radio frequency magnetic fields, we demonstrate that intrinsic and random spin fluctuations even in strictly unpolarized ensembles can reveal underlying patterns of correlation and ...
A bstract We propose a twin Pati-Salam (PS) theory of flavour broken to the G 4321 gauge group at high energies, then Standard Model low yielding TeV scale vector leptoquark $$ {U}_1^{\mu } U 1 μ (3 , 1 2 / 3) which has been suggested address lept...
We resolve the remarkably sharp bound exciton transitions of highly enriched 28Si using a single-frequency laser and photoluminescence excitation spectroscopy, as well as photocurrent spectroscopy. Well-resolved doublets in the spectrum of the 31P donor reflect the hyperfine coupling of the electronic and nuclear donor spins. The optical detection of the nuclear spin state, and selective pumpin...
