We study the open-string moduli of supersymmetric D6-branes, addressing both the string and field theory aspects of D6-brane splitting on Type IIA orientifolds induced by open-string moduli Higgsing (i.e., their obtaining VEVs). Specifically, we focus on the Z 2 × Z 2 ori-entifolds and address the symmetry breaking pattern for D6-branes parallel with the orientifold 6-planes as well as those po...

Splitting spunlaid composite filament is a most significant technique to manufacture nonwoven with microfibers. The splitting effect of composite filament is a direct impact on the performance of the final products. The paper summarizes present methods of splitting composite fibers at home or abroad, and the principle and characteristic of each method is also described in order to discuss the m...

Large spin-splitting in the conduction band and valence band of ferromagnetic semiconductors, predicted by the influential mean-field Zener model and assumed in many spintronic device proposals, has never been observed in the mainstream p-type Mn-doped ferromagnetic semiconductors. Here, using tunnelling spectroscopy in Esaki-diode structures, we report the observation of such a large spontaneo...

for solving large sparse non-hermitian positive definite linear equations, bai et al. proposed the hermitian and skew-hermitian splitting methods (hss). they recently generalized this technique to the normal and skew-hermitian splitting methods (nss). in this paper, we present an accelerated normal and skew-hermitian splitting methods (anss) which involve two parameters for the nss iteration. w...

let φ be a w  -continuous homomorphism from a dual banach algebra to c. the notion of φ-connes amenability is studied and some characterizations is given. a type of diagonal for dual banach algebras is dened. it is proved that the existence of such a diagonal is equivalent to φ-connes amenability. it is also shown that φ-connes amenability is equivalent to so-called φ-splitting of a certain s...

The electron spin resonance (ESR) spectra of 15NOand 14NO-ligated Hb Kansas have been measured at 77 K in the range of pH 5 to 10. At low pH the ESR spectrum is the composite of a type I and a type II spectrum which changes to another composite of a type I and type II spec­ trum at high pH. For the definition of type I and type II spectra and the correlation of these types with two tertiary con...
