The local and global properties of the Goetz thick plane domain wall space-time are studied. It is found that when the surface energy of the wall is greater than a critical value σc, the space-time will be closed by intermediate singularities at a finite proper distance. A model is presented in which these singularities will give rise to scalar ones when interacting with null fluids. The maximu...

A rockburst is a geological disaster that occurs in resource development or engineering construction. In order to reduce the harm caused by rockburst, this paper proposes prediction study of propensity based on intuitionistic fuzzy set-multisource combined weights-improved attribute measurement model. From perspective rock mechanics, uniaxial compressive strength σc, tensile stress σt, shear σθ...

We present ΣC, a programming model and language for high performance embedded manycores. The programming model is based on process networks with non determinism extensions and process behavior specifications. The language itself extends C, with parallelism, composition and process abstractions. It is intended to support architecture independent, high-level parallel programming on embedded manyc...

The critical two-terminal conductance gc and the spatial fluctuations of critical eigenstates are investigated for a disordered two dimensional model of non-interacting electrons subject to spin-orbit scattering (Ando model). For square samples, we verify numerically the relation σc = 1/[2π(2−D(1))] e /h between critical conductivity σc = gc = (1.42 ± 0.005) e /h and the fractal information dim...

We present a novel approach to the analysis of the normal state in-plane σab and out-of-plane σc conductivities of anisotropic layered crystals such as oxygen deficient Y Ba2Cu3Ox. It can be shown that the resistive anisotropy is determined by the ratio of the phase coherence lengths in the respective directions; i.e., σab/σc = l 2 ab/l 2 c . From the idea that at all doping levels and temperat...

The possibility that the masses M• of supermassive black holes (SBHs) correlate with the total gravitational mass of their host galaxy, or the mass MDM of the dark matter halo in which they presumably formed, is investigated using a sample of 16 spiral and 20 elliptical galaxies. The bulge velocity dispersion σc, typically defined within an aperture of size R < ∼ 0.5 kpc, is found to correlate ...

Rockburst is a complex destabilization phenomenon which combination of multiple factors, the study rockburst for classification prediction can help prevent and control engineering geological hazards, reduce casualties property damage. To achieve efficient accurate solve problem propensity assessment, six evaluation factors are selected as rock explosion system: tangential stress σθ, uniaxial co...

The measured masses of the three charge states of the charmed Σc baryon are found to be in disagreement with a sum rule based on the quark model, but relying on no detailed assumptions about the form of the interaction. This poses a significant problem for the charmed baryon sector of the quark model. Other relations among charmed baryon masses are also discussed. PACS numbers: 12.40.Yx., 14.20...

Rockbursts represent hazardous dynamic disasters for underground coal mines and other rock engineering projects. Some bursting liability indices are put forward applied to identify the likelihood of burst occurrence. The classification criteria proved be reasonable coals, but they still immature non-coal rocks. Thus, it is uncertain that use evaluating Hence, in this study, a large amount data,...
