In the rat beta-tropomyosin (beta-TM) gene, exons 6 and 7 are spliced alternatively in a mutually exclusive manner. Exon 6 is included in mRNA encoding nonmuscle TM-1, whereas exon 7 is used in mRNA encoding skeletal muscle beta-TM. Previously, we demonstrated that a six nucleotide mutation at the 5' end of exon 7, designated as ex-1, activated exon 7(More)
The rat beta-tropomyosin (beta-TM) gene encodes both skeletal muscle beta-TM mRNA and nonmuscle TM-1 mRNA via alternative RNA splicing. This gene contains eleven exons: exons 1-5, 8, and 9 are common to both mRNAs; exons 6 and 11 are used in fibroblasts as well as in smooth muscle, whereas exons 7 and 10 are used in skeletal muscle. Previously we(More)
Radial profiles of nuclear burn in directly-driven, inertial-confinement-fusion implosions have been systematically studied for the first time using a proton emission imaging system sensitive to energetic 14.7-MeV protons from the fusion of deuterium (D) and 3-helium (3 He) at the OMEGA laser facility [T. R. Experimental parameters that were varied include(More)
A new functionalized [60]fullerene-glycidyl azide polymer (C60-GAP) was synthesized for the first time using a modified Bingel reaction of [60]fullerene (C60) and bromomalonic acid glycidyl azide polymer ester (BM-GAP). The product was characterized by Fourier transform infrared (FTIR), ultraviolet-visible (UV-Vis), and nuclear magnetic resonance(More)
A proton emission imaging system has been developed and used extensively to measure the nuclear burn regions in the cores of inertial confinement fusion implosions. Three imaging cameras, mounted to the 60-beam OMEGA laser facility [T. R. Boehly et al., Opt. Commun. 133, 495 (1997)], use the penetrating 14.7-MeV protons produced from D 3 He fusion reactions(More)
Two-dimensional arrays of low capacitance tunnel junctions: general properties, phase transitions and Hall effect Abstract. We describe transport properties of two-dimensional arrays of low capacitance tunnel junctions, such as the current voltage characteristic and its dependence on external magnetic field and temperature. We discuss several experiments in(More)
We report the experimental observation of the recently predicted peaks on the I-V curve of the superconducting single-electron transistor at relatively high temperatures. The peaks are due to the matching of singularities in the quasiparticle density of states in two electrodes of a tunnel junction. The energy shift due to Coulomb blockade provides the(More)
Fast electron transport has been examined in the single particle regime in cold matter and in a fully ionized, classical cold plasma of solid-density using the Monte Carlo code ITS 3.0 and the CELSA plasma model by Li and Petrasso. Primary electron penetration in DT ice has been found to be ~40% larger than in a DT plasma of equivalent density. This is(More)
