The need for technological progress in bio-diagnostic assays of high complexity requires both fundamental research and constructing efforts on nano-scaled assay recognition elements that can provide unique selectivity and design-enhanced sensitivity features. Nanoparticle induced sensitivity enhancement and its application related to multiplexed capability Surface-Enhanced InfraRed Absorption (...
A measurement of the hadron energy spectrum in inclusive semileptonic B decays is proposed as a viable method for extracting |Vub|. Compared to the traditional energy spectrum of the charged lepton, the hadron energy spectrum exhibits kinematical advantages such as a wider energy window and a larger signal branching fraction. It is emphasized that the hadron energy spectrum method is most suite...
We prove by elementary methods the following generalization of a theorem due to Gleason, Kahane, and Żelazko. Let A be a real algebra with unit 1 such that the spectrum of every element in A is bounded and let φ : A→ C be a linear map such that φ(1) = 1 and (φ(a))2 + (φ(b))2 = 0 for all a, b in A satisfying ab = ba and a2 + b2 is invertible. Then φ(ab) = φ(a)φ(b) for all a, b in A. Similar resu...
The first dataset of a complete year of biologically damaging spectral UV at a sub-tropical latitude in the southern hemisphere has been presented. The new data provides a baseline dataset against which comparisons can be made in the future to establish if there have been any long term trends in the biologically damaging UV. The general shape of the variation of the daily biologically damaging ...
The majority of the proposed graphene-based THz devices consist of a metamaterial that can optically interact with graphene. This coupled graphene-metamaterial system gives rise to a family of resonant modes such as the surface plasmon polariton (SPP) modes of graphene, the geometrically induced SPPs, also known as the spoof SPP modes, and the Fabry-Perot (FP) modes. In the literature, these mo...
In this talk, we review the QCD calculations of the lepton spectrum from inclusive semileptonic B decay. We compare this prediction to that of the ACCMMmodel. This latter work was done in collaboration with Csaba Csaki. Invited Talk, Presented at WHEPP-3 Workshop in Madras This work is supported in part by funds provided by the U.S. Department of Energy (DOE) under contract #DE-AC02-76ER03069 a...
In this paper, we used cloud imagery from a NASA field experiment in conjunction with three-dimensional radiative transfer calculations to show that cloud spatial structure manifests itself as a spectral signature in shortwave irradiance fields - specifically in transmittance and net horizontal photon transport in the visible and near-ultraviolet wavelength range. We found a robust correlation ...

Abstract We compute the real space galaxy power spectrum, including leading order effects of General Relativity and primordial non-Gaussianity from f NL g parameters. Such contributions come one-loop matter spectrum terms dominant at large scales, factors non-linear bias parameter b (akin to Newtonian ? ). assess detectability these in Stage-IV surveys. In particular, we note that specific valu...
