Shape memory and magnetic properties of a Ni43Co7Mn39Sn11 Heusler polycrystalline alloy were investigated by differential scanning calorimetry, the sample extraction method, and the three-terminal capacitance method. A unique martensitic transformation from the ferromagnetic parent phase to the antiferromagneticlike martensite phase was detected and magnetic-field-induced “reverse” transition w...

Diffusion characteristics of cobalt atoms were investigated using radioactive isotope method in phase-hardened Fe-18wt.%Mn-2wt.%Si alloy. The observed significant increase of diffusion coefficient of cobalt atoms under the cyclic γ-ε-γ martensitic transformations was due to the action of two independent mechanisms - an athermal one and a thermally activated one. The first one arose from the dir...

Background: Despite advances toward an improved understanding of the evasive mechanisms leading to the establishment of cystic echinococcosis, the discovery of specific immunosuppressive mechanisms and related factors are of great interest in the development of an immunotherapeutic approach. Objective: To elucidate immunosuppressive effects of bioactive factors contained in chromatographic frac...

Increased downscaling of CMOS circuits with respect to feature size and threshold voltage has a result of dramatically increasing in leakage current. So, leakage power reduction is an important design issue for active and standby modes as long as the technology scaling increased. In this paper, a simultaneous active and standby energy optimization methodology is proposed for 22 nm sub-threshold...

Avilamycin is an antibiotic complex produced by cultures of the organism Streptomyces viridochromogenes, strain NRRL 2860. These compounds belong to the orthosomycin family of antibiotics. Structural composition of the major avilamycins and several minor avilamycins are known. Nine additional minor avilamycins, designated F through N, have been isolated via semi-preparative silica gel or revers...

It has previously been reported that a peak at the spectral position of the second harmonic of an excitation laser can be generated in an inversion-symmetric medium in the regime of extreme nonlinear optics and that this peak may be exploited to measure the carrier-envelope phase of the excitation pulse. Here we revisit this phenomenon with regard to reverse engineering the carrier-envelope pha...

Sodium overload of cardiac cells can accompany various pathologies and induce fatal cardiac arrhythmias. We investigate effects of elevated intracellular sodium on the cardiac action potential (AP) and on intracellular calcium using the Luo-Rudy model of a mammalian ventricular myocyte. The results are: 1) During rapid pacing, AP duration (APD) shortens in two phases, a rapid phase without Na(+...

maternal leukemia inhibitory factor (lif) is required for successful implanta¬tion in mice, but little is known about its role and expression in human reproduc¬tion. here we report on the pattern of lif mrna expression in 30 samples of previously fertile and 11 infertile human endometrium, 10 samples of previously fertile post-menopausal endometrium and 10 uterine (fallopian) tubes from pre¬vio...
