The magnetization of a ferromagnet (F) driven out of equilibrium injects pure spin current into an adjacent conductor (N). Such F|N bilayers have become basic building blocks in a wide variety of spin-based devices. We evaluate the shot noise of the spin current traversing the F|N interface when F is subjected to a coherent microwave drive. We find that the noise spectrum is frequency independe...

The current communication signifies the effect of oxygen vacancies (OVs) both qualitatively and quantitatively in multiferroic BiFe0.83Ni0.17O3 by an in-depth atomic-level investigation of its electronic structure and magnetization properties, and these materials have a variety of applications in spintronics, optoelectronics, sensors and solar energy devices. Depending on the precise location o...

This paper focuses on the study of MAC protocol in industrial wireless ad-hoc network, aiming at improving the fairness of industrial wireless ad-hoc network and quality of service (QOS). As a result, Hybrid Bi-channel Improvement of CSMA/CA mechanism and Dynamic Time Slot of TDMA mechanism MAC (B-T-MAC) is proposed. This protocol using the super frame structure, adopts the methods of bi-channe...

We show that the commonly known conductor boundary conditions E|| = B⊥ = 0 can be realized in two ways which we call ’thick’ and ’thin’ conductor. The ’thick’ conductor is the commonly known approach and includes a Neumann condition on the normal component E⊥ of the electric field whereas for a ’thin’ conductor E⊥ remains without boundary condition. Both types describe different physics already...

Conductor is a numerical invariant of a variety over a local field measuring the wild ramification of the inertia action on the l-adic etale cohomology. In [3], S.Bloch proposes a conjectural formula, Conjecture 1.9, which we call the conductor formula of Bloch. To formulate it, he defines another numerical invariant as the degree of the self-intersection class, which is defined using the local...

The Mott metal-insulator transition, a paradigm of strong electron-electron correlations, has been considered as a source of intriguing phenomena. Despite its importance for a wide range of materials, fundamental aspects of the transition, such as its universal properties, are still under debate. We report detailed measurements of relative length changes ΔL/L as a function of continuously contr...

The suppression of electromagnetic interferences (EMIs) caused by the out-of-band operation is required for broadband antennas. To achieve this purpose, a compact broadband printed slot antenna with build-in filters for band notching is presented. The filters, including I-shaped and inverse L-shaped narrow slits and an L-shaped conductor strip, whose lengths correspond to half wavelengths, were...

Advances in High Temperature Superconductors (HTS) are enabling a new class of synchronous rotating machines (SuperMotors and SuperGenerators) that can generically be categorized as SuperMachines. Compared to conventional machines of equivalent rating, these SuperMachines are expected to be less expensive, lighter, more compact, efficient, and provide significantly superior stable operation in ...

in this paper, we introduce and study the prime, strongly prime,semiprime and irreducible fuzzy bi-ideals of a semigroup. we characterize thosesemigroups for which each fuzzy bi-ideal is semiprime. we also characterizethose semigroups for which each fuzzy bi-ideal is strongly prime.
