    Many American states have statutes limiting transmission of monies from estates in this country to citizens of countries behind the Iron Curtain. American courts have come under heavy criticism for construing these statutes unfavorably to foreign heirs, especially where transmission to heirs in the Soviet Union is withheld. This article analyzes the relevant American and Soviet law and concludes that American courts, while they have not always been completely objective, nevertheless may be justified in withholding distribution from Soviet citizens

    Spin-pumping generates pure spin currents in normal metals at the ferromagnet (F)/normal metal (N) interface. The efficiency of spin-pumping is given by the spin mixing conductance, which depends on N and the F/N interface. We directly study the spin-pumping through an MgO tunnel-barrier using the inverse spin Hall effect, which couples spin and charge currents and provides a direct electrical detection of spin currents in the normal metal. We find that spin-pumping is suppressed by the tunnel-barrier, which is contrary to recent studies that suggest that the spin mixing conductance can be enhanced by a tunnel-barrier inserted at the interface

    This study was performed to investigate the different methods of treating hyper granulation tissue on experimentally induced wounds in equine limbs. Wounds were induced by removal of a skin patch and subcutaneous tissue for about 5-7 cm width and 6-8 cm in length from the dorsal and lateral aspect of the fore and hind limbs below the carpal and tarsal joints. The wounds were left open without treatment and the animals were trained 2-2.5 hours every day for about 3-5 weeks until hyper granulation tissue was developed. The schedule for the treatment of hyper granulation was divided into five groups each contained eight wounds of hyper granulation tissue; each main group was divided into two subgroups. The subgroups of first, second, third, fourth and fifth groups were treated by the following schedules: bandage alone; copper sulphate ointment 10%; silver nitrate ointment 2%; red mercury ointment 11%; and laser therapy (at a total dose of 9.72 Joule / cm2) respectively. While the second subgroups were treated by surgical resection of the hyper granulation tissue, followed by the same treatments applied on the first subgroup. The bandage for all experimental groups was changed every 48 hours until healing was occurred. The clinical and histological observation of the first group revealed that the healing take long period comparing with other groups. The mean of wound healing were 65 days in non surgical removal of hyper granulation tissue subgroup, while 57 days in surgical removed of hyper granulation tissue subgroup. The results of the second, third, fourth groups revealed that the caustic material especially red mercury has a role in healing processes through depressing the hyper granulation tissue. The mean of wound healing of the second group was 42.25 days in non surgical removal of hyper granulation tissue subgroup while 37.25 days in surgically removed hyper granulation tissue subgroup. In the third group the mean of wound healing was 45.75 days in non surgical removal of hyper granulation tissue subgroup while 44.75 days in surgically removed hyper granulation tissue subgroup. While in the fourth group the mean of wound healing was 39 days in non surgical removal of hyper granulation tissue subgroup while 36 days in surgically removed hyper granulation tissue subgroup. In the fifth group the clinical and histological observation revealed that the using of laser lead to reduce the period for wound healing significantly comparing with other groups. The mean of wound healing was 25 days in non surgical removal of hyper granulation tissue subgroup while 20 days in surgically removed hyper granulation tissue subgroup, so that the laser was the best in this study and the using of surgical removal is better than of non surgical removal

    Exploring water adsorption on isoelectronically doped graphene using alchemical derivatives

    The design and production of novel 2-dimensional materials has seen great progress in the last decade, prompting further exploration of the chemistry of such materials. Doping and hydrogenating graphene is an experimentally realised method of changing its surface chemistry, but there is still a great deal to be understood on how doping impacts on the adsorption of molecules. Developing this understanding is key to unlocking the potential applications of these materials. High throughput screening methods can provide particularly effective ways to explore vast chemical compositions of materials. Here, alchemical derivatives are used as a method to screen the dissociative adsorption energy of water molecules on various BN doped topologies of hydrogenated graphene. The predictions from alchemical derivatives are assessed by comparison to density functional theory. This screening method is found to predict dissociative adsorption energies that span a range of more than 2 eV, with a mean absolute error <0.1<0.1 eV. In addition, we show that the quality of such predictions can be readily assessed by examination of the Kohn-Sham highest occupied molecular orbital in the initial states. In this way, the root mean square error in the dissociative adsorption energies of water is reduced by almost an order of magnitude (down to 0.02\sim0.02 eV) after filtering out poor predictions. The findings point the way towards a reliable use of first order alchemical derivatives for efficient screening procedures

    Spreads of PG(3,q)PG(3,q) and ovoids of polar spaces

    To any spread S of PG(3,q) corresponds a family of locally hermitian ovoids of the Hermitian surface H(3, q^2), and conversely; if in addition S is a semifield spread, then each associated ovoid is a translation ovoid, and conversely. In this paper we calculate the translation group of the locally hermitian ovoids of H(3,q^2) arising from a given semifield spread, and we characterize the p-semiclassical ovoid constructed by Cossidente, Ebert, Marino and Siciliano as the only translation ovoid of H(3,q^2) whose translation group is abelian. If S is a spread of PG(3,q) and O(S) is one of the associated ovoids of H(3,q^2), then using the duality between H(3,q^2) and Q^-(5, q) , another spread of PG(3,q) , say S_1, can be constructed. On the other hand, using the Barlotti-Cofman representation of H(3,q^2), one more spread of a 3-dimensional projective space, say S_2, arises from the ovoid O(S). Lunardon has posed some questions on the relations among S, S_1 and S_2; here we prove that the three spreads are always isomorphic

    Detection and quantification of inverse spin Hall effect from spin pumping in permalloy/normal metal bilayers

    Full text link
    Spin pumping is a mechanism that generates spin currents from ferromagnetic resonance (FMR) over macroscopic interfacial areas, thereby enabling sensitive detection of the inverse spin Hall effect that transforms spin into charge currents in non-magnetic conductors. Here we study the spin-pumping-induced voltages due to the inverse spin Hall effect in permalloy/normal metal bilayers integrated into coplanar waveguides for different normal metals and as a function of angle of the applied magnetic field direction, as well as microwave frequency and power. We find good agreement between experimental data and a theoretical model that includes contributions from anisotropic magnetoresistance (AMR) and inverse spin Hall effect (ISHE). The analysis provides consistent results over a wide range of experimental conditions as long as the precise magnetization trajectory is taken into account. The spin Hall angles for Pt, Pd, Au and Mo were determined with high precision to be 0.013±0.0020.013\pm0.002, 0.0064±0.0010.0064\pm0.001, 0.0035±0.00030.0035\pm0.0003 and 0.0005±0.0001-0.0005\pm0.0001, respectively.Comment: 11 page

    A Bounded Affinity Theory of Religion and the Paranormal

    Get PDF
    We outline a theory of bounded affinity between religious experiences and beliefs and paranormalism, which emphasizes that religious and paranormal experiences and beliefs share inherent physiological, psychological, and ontological similarities. Despite these parallels, organized religious groups typically delineate a narrow subset of experiences and explanatory frames as acceptable and True, banishing others as either false or demonic. Accordingly, the theory provides a revised definition of the “paranormal” as beliefs and experiences explicitly rejected by science and organized religions. To demonstrate the utility of the theory, we show that, after controlling for levels of conventional religious practice, there is a strong, positive relationship between claiming Christian-based religious experiences and believing in, pursuing, and experiencing the paranormal, particularly among individuals not strongly tethered to organized religion. Bounded affinity theory makes sense of recent non-linear and complex moderation findings in the empirical literature and reiterates the importance of the paranormal for studies of religion

    Quantifying spin Hall angles from spin pumping: Experiments and Theory

    Full text link
    Spin Hall effects intermix spin and charge currents even in nonmagnetic materials and, therefore, ultimately may allow the use of spin transport without the need for ferromagnets. We show how spin Hall effects can be quantified by integrating permalloy/normal metal (N) bilayers into a coplanar waveguide. A dc spin current in N can be generated by spin pumping in a controllable way by ferromagnetic resonance. The transverse dc voltage detected along the permalloy/N has contributions from both the anisotropic magnetoresistance (AMR) and the spin Hall effect, which can be distinguished by their symmetries. We developed a theory that accounts for both. In this way, we determine the spin Hall angle quantitatively for Pt, Au and Mo. This approach can readily be adapted to any conducting material with even very small spin Hall angles.Comment: 4 pages, 4 figure
