Evidence for a current-induced spin-transfer torque effect has been investigated in a series of point contacts to single ferromagnetic layers. At specific current densities, abrupt resistance changes, similar to those attributed to current-induced spin-wave excitations in multilayers, have been observed for one current polarity. The critical current for these resistance changes depends linearly...

We study the consequences of positive correlation of beliefs in the design of voting rules in a model with an arbitrary number of voters. We propose a notion of positive correlation, based on the likelihood of agreement of the k best alternatives (for any k) of two orders called TS correlation. We characterize the set of Ordinally Bayesian Incentive-Compatible (OBIC) (d’Aspremont and Peleg (198...

The theoretical description used for the analysis of beam-voltage dependent CL and ERIC contrasts from a surface-parallel dislocation is summarized. The importance of the use of a realistic carrier generation model is discussed and suitable methods of the evaluation of defect parameters (depth position, dcfect strength) are proposed.

125301-7474 IJET-IJENS @ February 2012 IJENS I J E N S Abstract—To better understand the vacuum arc remelting (VAR) process, a 3D finite element model is established to analyzing the electromagnetic, temperature and flow fields of titanium alloy ingot during steady state melting process using ANSYS software. The research results show that the current flows from the crucible to consumable electr...

We study deterministic voting mechanisms by considering an ordinal notion of Bayesian incentive compatibility (OBIC). If the beliefs of agents are independent and generic, we show that a mechanism is OBIC and satisfies an additional condition called elementary monotonicity if and only if it is a dominant strategy incentive compatible mechanism. Our result works in a large class of preference do...

Although abortion services in India were liberalized more than three decades ago, access to safe services remains limited for the vast majority of women. This paper synthesises recent evidence on the induced abortion scen ario in India, and explores some of the factors why women continue to seek and receive abortion services from unqualified providers. The review highlights that a host of facto...

Objective(s): Stress alters sensory and cognitive function in humans and animals. Angiotensin (AT) receptors have demonstrated well-established interactions in sets of physiological phenomena. AT1 receptors can play a part in stress-induced activation of hypothalamic-pituitary-adrenal (HPA) axis; besides angiotensinergic neurotransmission plays a pivotal role in stress-evoked physiological resp...
