TL;DR: In this paper, laboratory measurement confirmed a relationship between leaf water status and the normalized difference water index (NDWI), derived from near-infrared and short-waveinfrared spectral data, and developed a vegetation dryness index (VDI) to estimate global vegetation water content.

TL;DR: In this paper, a multilevel scheme that exploits the locality of the theory was proposed to reduce the statistical errors in such calculations in SU(3) theory, for the case of the Polyakovloop correlation function.
Abstract: In non-abelian gauge theories without matterelds, expectation values oflargeWilsonloopsandloopcorrelationfunctionsaredicult tocomputethrough numerical simulation, because the signal-to-noise ratio is very rapidly decaying for increasing loop sizes. Using a multilevel scheme that exploits the locality of the theory, we show that the statistical errors in such calculations can be exponentially reduced. We explicitly demonstrate this in the SU(3) theory, for the case of the Polyakovloopcorrelationfunction,wheretheeciencyofthesimulationisimproved by many orders of magnitude when the area bounded by the loops exceeds 1fm 2 .

TL;DR: To elucidate the pathogenic contribution of a potent vasoconstrictor, endothelin-1, to coronary artery spasm, provoked spasm with intracoronary administration of acetylcholine or ergonovine and performed sensitive immunoassays of plasma levels of endothelins-1 and atrial natriuretic factor in the peripheral vein and coronary sinus of patients with a tentative diagnosis of vasospastic angina.
Abstract: To elucidate the pathogenic contribution of a potent vasoconstrictor, endothelin-1, to coronary artery spasm, we provoked spasm with intracoronary administration of acetylcholine or ergonovine and performed sensitive immunoassays of plasma levels of endothelin-1 and atrial natriuretic factor (ANF) in the peripheral vein and coronary sinus of patients with a tentative diagnosis of vasospastic angina (VSA, n = 19). The validity of coronary sinus blood sampling was verified by simultaneous measurement of the ANF level. The plasma endothelin-1 levels in venous and coronary sinus blood of the spasm-provoked patients (n = 12) were 1.71-fold and 2.16-fold higher, respectively, than those of nonprovoked cases (n = 5, p less than 0.01). During left coronary spasm, the endothelin-1 level in coronary sinus transiently decreased from 2.27 +/- 0.14 to 1.76 +/- 0.14 pg/ml (p less than 0.01) and returned to the control level (1.98 +/- 0.20 pg/ml) after the spasm resolved, whereas the change was equivocal during right coronary spasm. In contrast, the patients in whom spasm was not provoked showed no changes and maintained low endothelin-1 levels both before and after the maximal provocation (0.90 +/- 0.13 versus 0.90 +/- 0.13 pg/ml).(ABSTRACT TRUNCATED AT 250 WORDS)

TL;DR: Thermoelectrics, the direct solid-state conversion of waste heat to electricity, is a promising field with potential wide-scale application for power generation, and nanocomposite materials with hybrid effects and use of magnetism are emerging as novel bottom-up methods to enhance TE.
Abstract: Thermoelectrics (TE), the direct solid-state conversion of waste heat to electricity, is a promising field with potential wide-scale application for power generation. Intrinsic conflicts in the requirements for high electrical conductivity but (a) low thermal conductivity and (b) a large Seebeck coefficient have made enhancing TE performance difficult. Several recent striking advances in the field are reviewed. In regard to the former conflict, notable bottom-up nanostructuring methods for phonon-selective scattering are discovered, namely using nanosheets, dislocations, and most strikingly a process to fabricate nano-micropores leading to a 100% enhancement in the figure of merit (ZT ≈ 1.6) for rare-earth-free skutterudites. Porous materials are hitherto considered as having poor TE performance, so this is a new paradigm. In regard to the latter conflict, nanocomposite materials with hybrid effects and use of magnetism are emerging as novel bottom-up methods to enhance TE. Material informatics efforts to identify high-ZT materials are also reviewed.
