Practitioners should consider supplementing horses with neurologic disorders with micellized natural vitamin E at a level of 5–10 IU per lb body weight (10–20 IU per kg). A 1,000-lb. horse should receive 5,000–10,000 IU daily. Authors’ addresses: 2414 1st Avenue #506, Seattle, Washington 98121 (Kane); 112 Bedford Road, Bedford, Texas 76022 (Stuart) and University of California, 1 Shields Avenue...
According to the editors' themselves, their edition is "a theoretical structure, a complex hypothesis designed to account for a body of phenomena in the light of knowledge about the circumstances which generated them" (212). Needless to say, this "body of phenomena" is problematic to a degree. Patterson studies the evolution of Kane and Donaldson's "complex hypothesis" about these phenomena as ...
در این مقاله با استفاده از تئوری سیسستمهای جرم متغیر و تحلیلهای دینامیکی، رفتار چرخشی استوانهای با جرم متغیر مورد ارزیابی قرارگرفته است. اثرات سرعتهای زاویهای، نحوه کاهش جرم، متد سوزش سوخت، شکل و میزان کشیدگی هندسی در جهت محور تقارن استوانه در پایداری سیستم، شناخته شده است. نتایج حاصل از این مطالعه در واقع رویکردی به بررسی علت ایجاد تغییرات سریع و غیر منتظرانه در سرعتهای زاویهای راکته...
We introduce and empirically evaluate the strategy-affordance hypothesis, which holds that individual differences in strategy use will mediate the relationship between performance on a working memory (WM) span task and another cognitive task only when the same strategies are afforded by both tasks. One-hundred and forty eight participants completed basic memory tasks and verbal span tasks that ...
Two spins located at the edge of a quantum spin Hall insulator may interact with each other via indirect spin-exchange interaction mediated by helical states, namely RKKY interaction, which can be measured magnetic correlation between two spins. By means newly developed natural orbitals renormalization group (NORG) method, we investigated Kondo impurities interacting based on Kane-Mele model de...
We establish the equivalence between the problem of a potential scatterer in a Luttinger liquid of spinless repulsive fermions and an anisotropic Kondo model where the value of the impurity spin is determined by the scaling dimension of the scattering potential. The Bethe ansatz is used to derive non-perturbative expressions for the capacitance C(V ) and the conductance G(V) (V is the voltage)....
Introduction Klatzky (1980) described the working memory system as being a mental workbench using the analogy of a carpenters workbench. As a carpenter will lay out the tools and materials that they need for the job on their workbench so they are readily available, our mental workbench can hold ‘chunks’ of information that are required for our current cognitive goals. This workspace has limited...
The dependences of the partial coefficients interband two-photon absorption light, which differ from each other by types optical transitions, are analyzed depending on degree polarization and a quantitative analysis coefficient linear-circular dichroism light is carried out. Expressions obtained for spectral dependence in narrow-gap semiconductors Kane model. Keywords: initial, virtual final st...
增强石墨烯中的自旋轨道相互作用有可能实现无耗散的量子自旋霍尔器件,这需要在石墨烯样品中引入独特的Kane-Mele型自旋轨道相互作用,并保持较高的迁移率。然而,对石墨烯的外在修饰往往会引入“外秉型”Rashba自旋轨道相互作用,从而破坏了可能存在的拓扑态,并带来一定程度的杂质散射,降低样品迁移率。在石墨烯表面修饰EDTA-Dy分子后,可以看到显著的量子霍尔电导的平台,其弱局域化效应相比石墨烯被修饰之前得到了抑制,意味在石墨烯中可能引入了内秉的Kane-Mele型自旋轨道相互作用,增强了Elliot-Yafet型电子自旋弛豫机制。进一步通过矢量磁场磁阻测量,发现该分子覆盖在石墨烯上造成了石墨烯微弱的涟漪,这种涟漪引起的弯曲声子效应模拟了Kane-Mele型自旋轨道相互作用。
This work concerns the description of topological phases band insulators class DIII by using equivariant cohomology. The main result is definition a cohomology for general systems which generalizes well-known $$\mathbb {Z}_2$$ -invariant given Teo–Kane formula in one-dimensional case. In two-dimensional case, this invariant allows complete strong and weak phases. relation with KR-theory, Noethe...
