A bstract The strongly coupled heterotic M-theory vacuum for both the observable and hidden sectors of B ? L MSSM theory is reviewed, including a discussion “bundle” constraints that sector SU(4) vector bundle induced from single line must satisfy. Gaugino condensation then introduced within this context, bundles exhibit gaugino are presented. scale computed, singling out one whose associated l...

We have recently proposed the concept of soft N-modular redundancy (soft NMR) [1] in order to design robust and energy-efficient computing systems in nanoscale processes, where soft NMR was shown to achieve orders-of-magnitude improvement in robustness with significant power savings over NMR. In this paper, we analyze the performance of soft NMR and compare it with that of NMR and algorithmic n...

Soft-collinear effective theory is generalized to include soft massless quarks in addition to collinear fields. This extension is necessary for the treatment of interactions with the soft spectator quark in a heavy meson. The power counting of the relevant fields and the construction of the effective Lagrangian are discussed at leading order in Λ/mb. Several novel effects occur in the matching ...

In the multi-peta-flop era for supercomputers, the number of computing cores is growing exponentially. However, as integrated circuit technology scales below 65 nm, the critical charge required to flip a gate or a memory cell has been dangerously reduced, causing higher cosmic-radiations-induced soft error rate. Soft error threatens computing system by producing silently data corruption which i...

We calculate radiative corrections to the light-cone sum rule for the semileptonic form factor in B → πeν decays and thus remove the major uncertainty in determining the CKM mixing angle |Vub| by this method. We discuss the remaining uncertainties and perspectives for further studies. The structure of the radiative corrections suggests factorization of soft (end-point) and hard rescattering con...

In this work, we have studied the influence of dc joule-heating thermal processing on the structure, magnetoimpedance (MI) and thermal properties of Co64Fe4Ni2B19-xSi8Cr3Alx (x = 0, 1, and 2) rapidly solidified melt-spun ribbons. The nanocrystallization process was carried out by the current annealing of as-spun samples at various current densities. As-spun and joule-heated samples were studied...
