Transition metal (TM) defects in silicon carbide (SiC) are a promising platform quantum technology, especially because some TM emit the telecom band. We develop theory for interaction of an active electron $D$-shell defect SiC with nuclear spin and derive effective hyperfine tensor within Kramers doublets formed by spin-orbit coupling. Based on our we discuss possibility to exchange states pote...

I discuss gauge coupling unification in a class of superstring standard–like models, which are derived in the free fermionic formulation. Recent calculations indicate that the superstring unification scale is at O(10GeV ) while the minimal supersymmetric standard model is consistent with LEP data if the unification scale is at O(10)GeV . A generic feature of the superstring standard–like models...

The renormalization group equations (RGEs) of the mass matrices of quarks and leptons in a SO(10) model with two Higgs scalars in the Yukawa coupling are studied. This model is the minimal model of SUSY and non-SUSY SO(10) GUT which can reproduce all the experimental data. Non-SUSY SO(10) GUT model has the intermediate energy phase, Pati-Salam phase, and passes through the symmetry breaking pat...

We investigate supersymmetric hybrid inflation in a realistic model based on the gauge symmetry $SU(4)_c \times SU(2)_L SU(2)_R$. The minimal standard (MSSM) $\mu$ term arises, following Dvali, Lazarides, and Shafi, from coupling of MSSM electroweak doublets to singlet superfield which plays an essential role inflation. primordial monopoles are inflated away by arranging that SU(2)_R$ is broken...

Gamma oscillations were evoked in the subiculum in rat transverse hippocampal slices by tetanic stimulation (200 ms/100 Hz) of either CA1 or subiculum. Gamma oscillations in the subiculum differed from those in CA1 in containing population spike doublets as well as singlets. The present study addresses the origin of this more complex form of gamma oscillation in the subiculum. Intracellular rec...

Two basic technology gaps in today’s parallel computers are: 1) too much latency in accessing overall system memory, and 2) too little compiler power for existing languages. Consequently, the usability of massively parallel machines is limited. In this article we describe current parallel programming practice, and discuss the problems that need to be solved in order to make parallel programming...

Mammalian genomes are densely populated with long duplicated sequences. In this paper, we demonstrate the existence of doublets, short duplications between 25 and 100 bp, distinct from previously described repeats. Each doublet is a pair of exact matches, separated by some distance. The distribution of these intermatch distances is strikingly nonrandom. An unexpectedly high number of doublets h...

Abstract. Multiplet structure deconvolution provides a robust method to determine the values of coupling constants in first-order 1D nuclear magnetic resonance (NMR) spectra. Functions simplifying for partners with spin larger than 1/2 and doublets unequal amplitudes were introduced. The chemical shifts causing mild second-order effects can, favourable cases, be calculated from slopes measured ...
