Using low-resistance electrical contacts, we have measured the intrinsic high-field transport properties of metallic single-wall carbon nanotubes. Individual nanotubes appear to be able to carry currents with a density exceeding 109 A cm2. As the bias voltage is increased, the conductance drops dramatically due to scattering of electrons. We show that the(More)
BACKGROUND AND PURPOSE T16A(inh) -A01 is a recently identified inhibitor of the calcium-activated chloride channel TMEM16A. The aim of this study was to test the efficacy of T16A(inh) -A01 for inhibition of calcium-activated chloride channels in vascular smooth muscle and consequent effects on vascular tone. EXPERIMENTAL APPROACH Single channel and whole(More)
The reported thermal conductivity (kappa) of suspended graphene, 3000 to 5000 watts per meter per kelvin, exceeds that of diamond and graphite. Thus, graphene can be useful in solving heat dissipation problems such as those in nanoelectronics. However, contact with a substrate could affect the thermal transport properties of graphene. Here, we show(More)
TMEM16A (ANO1) is a calcium-activated chloride channel (CaCC) expressed in secretory epithelia, smooth muscle, and other tissues. Cell-based functional screening of ∼110,000 compounds revealed compounds that activated TMEM16A CaCC conductance without increasing cytoplasmic Ca(2+). By patch-clamp, N-aroylaminothiazole "activators" (E(act)) strongly increased(More)
As a part of a basic research project on Xeno-transplantion, we have been engaged in the derivation of embryonic stem cell lines from Chinese mini swine. Here, we reported for the first time the establishment of two porcine EG cell lines (BPEG1 and BPEG2) from primordial germ cells of genital ridges of a 28 and a 27 d embryos respectively. Their pluripotent(More)
Two gastropod species (Rapana venosa and Neverita didyma) and three bivalve species (Mytilus edulis, Crassostrea talienwhanensis and Ruditapes philippinarum) were collected from eight sites along the coastline of the Chinese Bohai Sea for the investigation of heavy metal contaminations. Cd, Co, Cu, Ni, Pb and Zn were analyzed by using pressure(More)
The low-frequency electronic noise properties of individual single-wall metallic carbon nanotubes are investigated. The noise exhibits a 1/f frequency dependence and a V 2 voltage dependence. The noise power at 8 K appears to be three orders of magnitude smaller than at 300 K. As a demonstration of how these noise properties affect nanotube devices, a(More)
We have observed experimentally that the thermal conductance of a 2.76-microm-long individual suspended single-wall carbon nanotube (SWCNT) was very close to the calculated ballistic thermal conductance of a 1-nm-diameter SWCNT without showing signatures of phonon-phonon Umklapp scattering for temperatures between 110 and 300 K. Although the observed(More)
In this paper, we present a novel algorithm for restoration of noisy video sequences. A video sequence is first transformed into an optimal 3D wavelet domain using basis functions adapted to the contents of the sequence. Assuming that all the major spatiotemporal frequency phenomena present in the sequence produce high amplitude transform coefficients, a(More)
Enzymatic antioxidant system plays an important role in maintaining seed vigor and regulating plant growth and development. It involves a number of enzymes that scavenge excessive reactive oxygen species (ROS) produced during seed aging and also modulate the level of these compounds during plant developmental processes. This study investigated the(More)
