We examined three parallel data sets with respect to qualities relevant to phylogenetic analysis of 20 exemplar monocotyledons and related dicotyledons. The three data sets represent restriction-site variation in the inverted repeat region of the chloroplast genome, and nucleotide sequence variation in the chloroplast-encoded gene rbcL and in the mitochondrion-encoded gene atpA, the latter of w...
Complex I (NADH:ubiquinone oxidoreductase) is central to cellular energy production, being the first and largest enzyme of the respiratory chain in mitochondria. It couples electron transfer from NADH to ubiquinone with proton translocation across the inner mitochondrial membrane and is involved in a wide range of human neurodegenerative disorders. Mammalian complex I is composed of 44 differen...
Features of high energy pp and pA elastic scattering at small t Abstract A method for the determination of the real part of the elastic scattering amplitude is examined for high energy proton-proton and proton-nuclei elastic scattering at small momentum transfer. This method allows us to decrease the number of model assumptions, to obtain the real parts of the spin-non-flip and spin-flip amplit...
The structure of jet-jet correlations is investigated in proton-proton (pp) collisions. We focus on the transmission of the initial transverse momenta of partons (" intrinsic k T ") to the hadron-hadron correlations. Values of the intrinsic transverse momentum obtained from experimental dijet correlations are compared to the results of our model calculation at ISR and RHIC energies. Procedures ...
A two-dimensional position-sensitive dosimetry system based on a scintillating gas detector is being developed for pre-treatment verification of dose distributions in particle therapy. The dosimetry system consists of a chamber filled with an Ar/CF(4) scintillating gas mixture, inside which two gas electron multiplier (GEM) structures are mounted (Seravalli et al 2008b Med. Phys. Biol. 53 4651-...
The structure of hadron-hadron correlations is investigated in proton-proton (pp) collisions. We focus on the transmission of the initial transverse momenta of partons (“intrinsic kT”) to the hadron-hadron correlations. Values of the intrinsic transverse momentum obtained from experimental correlations are compared to the results of a model with partially randomized parton transverse momenta at...
In our experiments, we use different photoresists for proton beam writing and mold fabrication. We have fabricated Ni mold with structures down to 500 nm. We first use a fine focused proton beam to expose different photoresists, Polymethyl Methacrylate (PMMA), AR-P 3250 and ma-N 2410. After development and nickel sulfamate electroplating, the structures were faithfully transferred from the phot...
Standard thermodynamic function changes (AGO”, AHe’, A&” and Acre”) are reported for proton dissociation of acridinium cation in aqueous solution. These values have been determined from a series of precise and accurate acid equilibrium constants, K,. The equilibrium constants have been obtained spectrophotometrically over a range of temperatures from 2 to 66°C at several ionic strengths (I = 0....
Fluorescence is not frequently used as a tool for investigating the photocycles of rhodopsins, largely because of the low quantum yield of the retinal chromophore. However, a new class of genetically encoded voltage sensors is based upon rhodopsins and their fluorescence. The first such sensor reported in the literature was the proteorhodopsin optical proton sensor (PROPS), which is capable of ...
Subunits 6 and 8 of the mitochondrial ATPase in Saccharomyces cerevisiae are encoded by the mitochondrial genome and translated from bicistronic mRNAs containing both reading frames. The stability of the two major species of ATP8/6 mRNA, which differ in the length of the 5'-untranslated region, depends on the expression of several nuclear-encoded factors. In the present study, the product of th...
