We describe the dynamics of magnetic skyrmions in synthetic antiferromagnets (SAF), with a finite interlayer coupling. Due to opposite gyrovector two SAF layers, coupled reach stationary regime spatial separation, direction orthogonal their velocity. As consequence, and contrary ferromagnetic situation, transient necessarily occurs, acceleration, related an inertia, that limits its time respons...

This paper describes the use of a system of semantic rules to generate noun compounds, vague or polyse-mous words, and cases of metonymy. The rules are bi-directional and are used by the understanding system to interpret the same constructions.

In this paper we develop two conforming finite element methods for a fourth order bi-wave equation arising as a simplified Ginzburg-Landau-type model for d-wave superconductors in absence of applied magnetic field. Unlike the biharmonic operator ∆2, the bi-wave operator 2 is not an elliptic operator, so the energy space for the bi-wave equation is much larger than the energy space for the bihar...

-Detailed neutron diffraction structure analysis of Bi2SrzCaCu20s is reported. The effects of Pb-substitution on BizSrzCaCuzOs and Bi2Sr2CuOs are discussed, and magnetization measurement results on the 110 K phase in the Bi-Sr-Ca-Cu-0 system are given. Since the discovery of high Tc superconductivity in the Bi-Sr-Ca-Cu-0 system [I], two superconducting phases have been unambiguously identified,...

The isostructural compounds Sr(4)Bi(3), Ba(4)Bi(3), and Ba(4)As( approximately )(2.60) were prepared by direct reactions of the corresponding elements and their structures determined from single-crystal X-ray diffraction data as anti-Th(3)P(4) type in the cubic space group I43d, Z = 4 (a = 10.101(1) A, 10.550(1) A, 9.973 (1) A, respectively). The two bismuth compounds are stoichiometric, and th...

In this paper we improve some mapping theorems on א-spaces. For instance we show that an א-space is preserved by a closed and countably bi-quotient map. This is an improvement of Yun Ziqiu’s theorem: an א-space is preserved by a closed and open map.

A fundamental task of data analysis is comprehending what distinguishes clusters found within the data. We present the problem of mining distinguishing sets which seeks to find sets of objects or attributes that induce that most change among the incremental bi-clusters of a binary dataset. Unlike emerging patterns and contrast sets which only focus on statistical differences between support of ...

BACKGROUND Medication-overuse headache (MOH) is common in the general population, and most patients are managed in primary health care. Brief Intervention (BI) has been used as a motivational technique for patients with drug and alcohol overuse, and may a have role in the treatment of MOH. AIM To explore GPs' experiences using BI in the management of patients with MOH. DESIGN AND SETTING Qu...

A new layered bismuth tellurium oxychloride, Bi(3)Te(4)O(10)Cl(5) has been synthesized by a solid-state reaction under vacuum using Bi(2)O(3), TeO(2), and TeCl(4) as reagents. The structure of Bi(3)Te(4)O(10)Cl(5) has been determined by single-crystal X-ray diffraction. Bi(3)Te(4)O(10)Cl(5) contains two different lone pair cations, Bi(3+) and Te(4+) that are in asymmetric coordination environme...
