Resistance (R) separation between high and low R states was 15.2σ, comparable to that for 80nm MTJ cells. Thermal stability factor (Δ) followed prediction fairly well, and MTJ with free layer (FL) of 25Å and aspect ratio (AR) of 3 showed Δ of 56. In order to realize sub-30nm MRAM device, a novel FL with substantially low critical current density (Jc) or revolutionary MTJ scheme needs to be developed.
Synthesis and QSAR study of novel cytotoxic spiro[3H-indole-3,2 0 (1 0 H)-pyrrolo [3,4-c]pyrrole]... more Synthesis and QSAR study of novel cytotoxic spiro[3H-indole-3,2 0 (1 0 H)-pyrrolo [3,4-c]pyrrole]-2,3 0 ,5 0 (1H,2 0 aH,4 0 H)-triones a b s t r a c t 1,3-Dipolar cycloaddition reaction of 1-aryl-1H-pyrrole-2,5-diones 1a-e with non-stabilized azomethine ylides, generated in situ via decarboxylative condensation of isatins 2aec and sarcosine (3) in refluxing ethanol, afforded 4 0 -aryl-5 0 a,6 0 -dihydro-1 0 -methyl-spiro[3H-indole-3,2 0 (1 0 H)-pyrrolo[3,4-c]pyrrole]-2,3 0 ,5 0 (1H,2 0 aH,4 0 H)-triones 4aeo in good yields. Compound 4l exhibited high anti-tumor activity against HEPG2 (liver cancer) cell line (IC 50 ¼ 12.16 mM) compared to that of Doxorubicin (IC 50 ¼ 7.36 mM), and the other synthesized compounds revealed moderate anti-tumor properties against HCT116 (colon), MCF7 (breast) and HEPG2 (liver) human tumor cell lines. 3D-Pharmacophore modeling and quantitative structure-activity relationship (QSAR) analysis were combined to explore the structural requirements controlling the observed anti-tumor properties. It was found that the major structural factors affecting potency of these compounds were related to their basic skeleton.

This introduces an extended electroweak symmetry group SU(2)L x SU(2)H at low energies.We recover the fermion spectra of an anomaly-free three-family 3-4-1 modelwithout exotic chargesfor U(1)X charge X = T3R+(B-L)/2.The interaction of physical neutral gauge bosons Zprime,Z double prime and exotic fermions are presented along with their masses and mixing angle.The electroweak constraints from oblique corections on the model are also calculated.

We explore the trade off between performance functions and yield estimation during the design optimization process. Through the integration of yield into the optimization process, the trade off between the performance functions can be better treated that able to produce a higher yield. This concept together with full circuit simulation and global search algorithm provides a robust solution across process corners and parameter variations. Encouraging results have been obtained and an example is presented to demonstrate the technique.

The $ {\text{K}}_{\text{S}}^0 $ , Λ, and Ξ− particles and their antiparticles are reconstructed from their decay topologies and the production rates are measured as functions of rapidity and transverse momentum, p T. The results are compared to other experiments and to predictions of the Pythia Monte Carlo program. The p T distributions are found to differ substantially from the Pythia results and the production rates exceed the predictions by up to a factor of three.
