ab initio calculation at hf/6-31g* level of theory for geometry optimization and mp2/6-31g*//hf/6-31g* for a single point total energy calculation are reported for the important energyminimumconformations and transition-state geometries of of cyclodeca-1,2,3-triene (1). the mostfavorable conformation of 1 is a unsymmetrical twist-chair (1-tc) structure. degenerateinterconversion of 1-tc with it...

– The mean time between submission and acceptance was 1.4 months. Also, since January 2007, the journal has been published in its entirety in English, in digital format, and freely accessible without subscription through MEDLINE. This online access has been a complete success. For the immediate future we have proposed the fulfillment of the dream of many members: to finally have an impact facto...

background: metastasis is one the most leading cause of death from cancer. the chemokine receptor of cxcr4 has an important role in cell migration and cancer metastasis. additionally, metastasis is always associated with the process of epithelial-mesenchymal transition (emt). in this study the correlation between expression of cxcr4 and emt-tfs has been examined. methods: the expression of cxcr...

we used qcd factorization for the hadronic matrix elements to show that the existing data, in particular the branching ratios br ( ?j/?k) and br ( ?j/??), can be accounted for this approach. we analyzed the decay within the framework of qcd factorization. we have complete calculation of the relevant hard-scattering kernels for twist-2 and twist-3. we calculated this decays in a special scale ( ...

X-ray diffraction imaging (XRDI) (topography) measurements of silicon die warpage within fully packaged commercial quad-flat no-lead devices are described. Using synchrotron radiation, it has been shown that the tilt lattice planes in Analog Devices AD9253 initially falls, but after 100 °C, rises again. The twist across wafer falls linearly with an increase temperature. At 200 varies approximat...
