A tunnel magnetic junction is considered with magnetic hard and magnetic soft layers of cubic symmetry. The magnetic switching is analyzed of the layers by a magnetic field perpendicular to the initial magnetizations. In such a situation, an additional peak of the TMR ratio appears at the magnetic field value lower substantially than the anisotropy energy of the soft layer.

Triple-negative breast cancers are an aggressive subtype of breast cancer with poor survival, but there remains little known about the etiologic factors that promote its initiation and development. Commonly inherited breast cancer risk factors identified through genome-wide association studies display heterogeneity of effect among breast cancer subtypes as defined by the status of estrogen and ...

In this paper we find necessary and sufficient conditions for the existence of a group divisible design GDD(n, m) of index (*1 , *2) in which n=2 or m=2, thereby completing the solution of the existence problem for all n, m, *1 , and *2 . In the process, necessary and sufficient conditions are found for the existence of an x-regular partial triple system whose complement in *Kn has a 1-factoriz...

A D(4)-m-tuple is a set of m integers such that the product of any two of them increased by 4 is a perfect square. A problem of extendibility of D(4)-m-tuples is closely connected with the properties of elliptic curves associated with them. In this paper we prove that the torsion group of an elliptic curve associated with a D(4)-triple can be either Z/2Z× Z/2Z or Z/2Z× Z/6Z.

Transcranial magnetic stimulation (TMS) is a non-invasive technique that uses transient field generated from electromagnetic coils in inducing electric to stimulate the neurons of brain. Various researchers have proposed coil designs for TMS aimed at achieving high focality and increased penetration depth induced In this article, authors compare figure eight (FOE) coil, quadruple butterfly (QBC...

Older drivers have one of the highest vehicle crash rates in comparison with other population groups, largely due to the functional effects of the accumulation, and progression of age-related deterioration in visual, cognitive and motor conditions that impact on fitness to drive (Molnar et al., 2007). Numerous studies indicate that the predominant casualty crash type for older drivers involved ...

The effect of spin relaxation on tunnel magnetoresistance (TMR) in a ferromagnet/superconductor/ferromagnet (FM/SC/FM) double tunnel junction is theoretically studied. The spin accumulation in SC is determined by balancing of the spin-injection rate and the spin-relaxation rate. In the superconducting state, the spinrelaxation time τs becomes longer with decreasing temperature, resulting in a r...

We use a two-person 3-stage game to investigate whether people choose to punish or reward another player by sacrificing money to increase or decrease the other person’s payoff. One player sends a message indicating an intended play, which is either favorable or unfavorable to the other player in the game. After the message, the sender and the receiver play a simultaneous 2x2 game. A deceptive m...

It is known that for a sequence of independent and identically distributed random variables (Xn) the regular variation condition is equivalent to weak convergence of partial maximaMn = max{X1, . . . , Xn}, appropriately scaled. A functional version of this is known to be true as well, the limit process being an extremal process, and the convergence takes place in the space of càdlàg functions e...
