We extend the picture of B-meson decay constants obtained in lattice QCD beyond those of the B, Bs and Bc to give the first full lattice QCD results for the B , B s and B c. We use improved nonrelativistic QCD for the valence b quark and the highly improved staggered quark (HISQ) action for the lighter quarks on gluon field configurations that include the effect of u=d, s and c quarks in the se...

We present a technique for patterning thin-film metals (silver and gold) without the need for photolithography. The technique involves microfluidics and can be performed on planar or curved surfaces. Patterns of thin-film metal are fabricated by flowing electroless silver or gold plating solutions through predefined microchannels made of polydimethylsiloxane sealed against a surface of interest...

The Kobayashi-Maskawa model for CP violation [1] passed in a remarkable way its first crucial test in B decays [2] when a large CP asymmetry was measured [3, 4] in B → J/ψKS in agreement with expectations. The virtue of this gold-plated decay mode is the absence of hadronic uncertainties [5, 6] in predicting the mixing induced asymmetry in terms of a fundamental phase parameter β ≡ φ1 of the St...

We present an update of results from the HPQCD collaboration on charm physics using the Highly Improved Staggered Quark action. This includes a precise determination of mc using moments of current-current correlators combined with high-order continuum QCD perturbation theory. We also include an update on the determination of αs from lattice QCD, preliminary results on the determination of mb an...

Non-leptonic Bs decays into CP eigenstates that are caused by b̄ → c̄cs̄ quark-level transitions, such as Bs → D s D s , J/ψ η ) or J/ψ φ, provide a powerful tool to search for “new physics”, as the CP-violating effects in these modes are tiny in the Standard Model. We explore these effects for a particular scenario of new physics, the left-right-symmetric model with spontaneous CP violation. In o...

In this study, we evaluated reactivity of organic peroxides with metals. The effect of useful metals for decomposition of organic peroxides was measured by Differential Scanning Calorimeter (DSC). Results of DSC measurement with several kinds of sample cells showed that some of organic peroxides have high reactivity with gold plated cell. Hydroperoxides were decomposed lower temperature by usin...

CP violation in the B system [1] has been established by the recent measurements of sin 2β, with a world average of sin 2β = 0.78 ± 0.08 [2]. The main B decay used to probe the weak phase β is the so-called “gold-plated” mode B d(t) → J/ψKS. In order to extract weak-phase information cleanly, i.e. with no hadronic uncertainties, a given B decay must be dominated by a single weak decay amplitude...

Data networking can aid disaster recovery efforts by allowing victims to contact rescuers, rescuers to communicate among themselves, and concerned friends and relatives to contact victims. Unfortunately, conventional data networks themselves are often destroyed by disasters, currently rendering these services unavailable. My thesis is that heterogeneous robust subnetworks that manage to survive...

We present an integrated chemical sensor array fabricated using a CMOS process followed by post-processing. The sensor presented in this paper incorporates 324 individually addressable sensing nodes. Post processing involves an electroless Nickel and Gold plating step to fabricate sensing contacts, and the deposition of a carbon black based polymer sensor material. The operation of the integrat...
