Sulfate aerosols exert profound impacts on human and ecosystem health, weather, and climate, but their formation mechanism remains uncertain. Atmospheric models consistently underpredict sulfate levels under diverse environmental conditions. From atmospheric measurements in two Chinese megacities and complementary laboratory experiments, we show that the… (More)

We construct concrete supersymmetric grand unified theories based on the Pati-Salam gauge group SU(4)c × SU(2)L × SU(2)R which naturally lead to a moderate violation of ‘asymptotic’ Yukawa unification and thus can allow an acceptable b-quark mass even with universal boundary conditions. We consider the constrained minimal supersymmetric standard model which… (More)

U(1) family symmetries have led to successful predictions of the fermion mass spectrum and the mixing angles of the hadronic sector. In the context of the supersymmetric unified theories, they further imply a non-trivial mass structure for the scalar partners, giving rise to new sources of flavor violation. In the present work, lepton flavor non-conserving… (More)

The heterogeneous chemistry of glyoxal on sulfuric acid surfaces has been investigated at various acid concentrations and temperatures, utilizing a low-pressure fast flow laminar reactor coupled to an ion drift-chemical ionization mass spectrometer (ID-CIMS). The uptake coefficient (γ) of glyoxal ranges from (1.2 ± 0.06) × 10(-2) to (2.5 ± 0.01) × 10(-3)… (More)

An improved analysis of the b → s + γ decay in the minimal flavor violating case is given taking into account additional contributions in the supersymmetric sector which enter in the next-to-leading-order (NLO) and are enhanced by tanβ factors. Specifically, we compute a set of twenty one-loop diagrams to give the most complete analysis to date of the NLO… (More)

An analysis of the sensitivity of supersymmetric dark matter to variations in the b quark mass is given. Specifically we study the effects on the neutralino relic abundance from supersymmetric loop corrections to the mass of the b quark. It is known that these loop corrections can become significant for large tanβ. The analysis is carried out in the… (More)

The minimal supersymmetric standard model with universal boundary conditions and ‘asymptotic’ Yukawa coupling unification is considered. The full one-loop effective potential for radiative electroweak symmetry breaking as well as the one-loop corrections to all the Higgs boson, b-quark and τ -lepton masses are included. The relic abundance of the lightest… (More)

Due to the intricacies of nanoscale design, abstract performance, area and power models of network-on-chip components need to be implementation-aware. In particular, the connection pattern of the network nodes has significant implications on the final layout performance, due to physical interconnect issues such as routing congestion, link power and hardly… (More)

The cosmological relic density of the lightest supersymmetric particle of the minimal supersymmetric standard model is calculated under the assumption of gauge and Yukawa coupling unification. We employ radiative electroweak breaking with universal boundary conditions from gravitymediated supersymmetry breaking. Coannihilation of the lightest supersymmetric… (More)

We compute the neutralino-nucleon cross section in several supersymmetric scenarios, taking into account all kind of constraints. In particular, the constraints that the absence of dangerous charge and colour breaking minima imposes on the parameter space are studied in detail. In addition, the most recent experimental constraints, such as the lower bound… (More)
