However, the physiological role of bNOS remains largely un... Potential for Wind-Generated Electricity in China [作者：McElroy, MB; Lu, X; Nielsen, CP; Wang, YX,期刊：Science, 页码：1378-1380 , 文章类型： Article，,卷期：2009年325-5946] Wind offers an important alternative to coal as a source of energy for generation of electricity in China with the potential for substantial savings in carbon dioxide emissions. Wind fields derived from assimilated meteo... Dynamic Processes Governing Lower-Tropospheric HDO/H2O Ratios as Observed from Space and Ground [作者：Frankenberg, C; Yoshimura, K; Warneke, T; Aben, I; Butz, A; Deutscher, N; Griffith, D; Hase, F; Notholt, J; Schneider, M; Schrijver, H; Rockmann, T,期刊：Science, 页码：1374-1377 , 文章类型： Article，,卷期：2009年325-5946] The hydrological cycle and its response to environmental variability such as temperature changes is of prime importance for climate reconstruction and prediction. We retrieved deuterated water/water (HDO/H2O) abundances ... Energy-Efficient Action Potentials in Hippocampal Mossy Fibers [作者：Alle, H; Roth, A; Geiger, JRP,期刊：Science, 页码：1405-1408 , 文章类型： Article，,卷期：2009年325-5946] Action potentials in nonmyelinated axons are considered to contribute substantially to activity-dependent brain metabolism. Here we show that fast Na+ current decay and delayed K+ current onset during action potentials i... Extremely Efficient Multiple Electron-Hole Pair Generation in Carbon Nanotube Photodiodes [作者：Gabor, NM; Zhong, ZH; Bosnick, K; Park, J; McEuen, PL,期刊：Science, 页码：1367-1371 , 文章类型： Article，,卷期：2009年325-5946] We observed highly efficient generation of electron-hole pairs due to impact excitation in single-walled carbon nanotube p-n junction photodiodes. Optical excitation into the second electronic subband E-22 leads to strik... Entropy Landscape of Phase Formation Associated with Quantum Criticality in Sr3Ru2O7 [作者：Rost, AW; Perry, RS; Mercure, JF; Mackenzie, AP; Grigera, SA,期刊：Science, 页码：1360-1363 , 文章类型： Article，,卷期：2009年325-5946] Low-temperature phase transitions and the associated quantum critical points are a major field of research, but one in which experimental information about thermodynamics is sparse. Thermodynamic information is vital for... 30,000-Year-Old Wild Flax Fibers [作者：Kvavadze, E; Bar-Yosef, O; Belfer-Cohen, A; Boaretto, E; Jakeli, N; Matskevich, Z; Meshveliani, T,期刊：Science, 页码：1359-1359 , 文章类型： Article，,卷期：2009年325-5946] Ecological Dynamics Across the Arctic Associated with Recent Climate Change [作者：Post, E; Forchhammer, MC; Bret-Harte, MS; Callaghan, TV; Christensen, TR; Elberling, B; Fox, AD; Gilg, O; Hik, DS; Hoye, TT; Ims, RA; Jeppesen, E; Klein, DR; Madsen, J; McGuire, AD; Rysgaard, S; Schindler, DE; Stirling, I; Tamstorf, MP; Tyler, NJC; van de,期刊：Science, 页码：1355-1358 , 文章类型： Review，,卷期：2009年325-5946] At the close of the Fourth International Polar Year, we take stock of the ecological consequences of recent climate change in the Arctic, focusing on effects at population, community, and ecosystem scales. Despite the bu... Went Fishing, Caught a Snake [作者：Meijer, D,期刊：Science, 页码：1353-1354 , 文章类型： Editorial Material，,卷期：2009年325-5946] MITEs-The Ultimate Parasites [作者：Gonzalez, J; Petrov, D,期刊：Science, 页码：1352-1353 , 文章类型： Editorial Material，,卷期：2009年325-5946]
