Understanding the dynamics and underlying mechanism of carbon exchange between terrestrial ecosystems and the atmosphere is one of the key issues in global change research. In this study, we quantified the carbon fluxes in different terrestrial ecosystems in China, and analyzed their spatial variation and environmental drivers based on the long-term… (More)
DNA methylation is a key epigenetic modification of DNA that is catalyzed by DNA methyltransferase (DNMT). Increasing evidence suggests that DNA methylation in neurons regulates synaptic plasticity as well as neuronal network activity. Here, we evaluated DNA methyltransferase 1 (Dnmt1) and Dnmt3a expression in brain tissues of epileptic patients to explore… (More)
Based on the model–data comparison at the eddy-covariance observation sites from CarboEastAsia datasets, we report the current status of the terrestrial carbon cycle modeling in monsoon Asia. In order to assess the modeling performance and discuss future requirements for both modeling and observation efforts in Asia, we ran eight terrestrial biosphere… (More)
The datasets of net ecosystem CO2 exchange (NEE) were acquired from 21 forests, 3 grasslands, and 3 croplands in the eastern part of Asia based on the eddy covariance measurements of the international joint program, CarboEastAsia. The program was conducted by three networks in Asia, ChinaFLUX, JapanFlux, and KoFlux, to quantify, synthesize, and understand… (More)
Ni(en)3·Hen·[B9O13(OH)4]·H2O was prepared under the cotemplating effect of [Ni(en)3](2+) and Hen(+). It was the first example of a cotemplated borate with an unusual chiral polyanionic chain, which was constructed from [B5O8(OH)2] and [B4O7(OH)2] clusters.
a r t i c l e i n f o Keywords: Digital camera Greenness index Phenological date Gross primary production Winter wheat Recent studies have shown that the greenness index derived from digital camera imagery has high spatial and temporal resolution. These findings indicate that it can not only provide a reasonable characterization of canopy seasonal variation… (More)
A zinc borate Zn(1,3-DAP)[B4O7] (1) was prepared. 1 was revealed to be a rare chiral zeolitic framework based on a [B4O9] cluster. The combination of a [B4O9] cluster and Zn(1,3-DAP)O3 chain produced a helical ribbon motif and gave rise to a single-stranded helical channel.
OBJECTIVE To examine the change in N-terminal pro-brain natriuretic peptide (Nt-proBNP) and big endothelin (big ET) in patients undergoing coronary artery bypass grafting (CABG), and to evaluate their value in predicting postoperative mortality and complication. METHODS Forty-seven patients undergoing coronary artery bypass grafting under on-pump (CCABG)… (More)
The title compound (GDUT-4) is the first templated borate compound shown to have ferroelectric properties. Its structure consists of a metal complex and isolated polyanion. The chiral structure of the compound was induced by guest-complex cations according to host-guest symmetry through hydrogen bonds (H-bonds). The origins of ferroelectricity in GDUT-4 was… (More)
