1Characterization of dissolved organic matter fractions from Lake Hongfeng, Southwestern China Plateau显示文摘With XAD-series and ion exchange resins, dissolved organic matter (DOM) from Lake Hongfeng in Southwestern China Plateau was isolated into 6 fractions, i.e., humic acid (HA), fulvic acid (FA), hydrophobic neutrals (HON), hydrophilic acids (HIA), hydrophilic bases (HIB) and hydrophilic neutrals (HIN). Those fractions were characterized by high performance size exclusion chromatography, fluorescence spectroscopy and UV absorbance. Among the 6 fractions, FA was predominant and accounted for 51% of the total DOM. The weight-average (Mw) and number-averaged (Mn) molecular weight of these fractions ranged from 1688 to 2355 Da and from 1338 to 1928 Da, respectively. A strong correlation was observed between specific UV absorbance at 280 nm, E2/E3 (absorbance at 250 nm to 365 nm), and the molecular weight for DOM fractions. UV-Vis fulvic-like fluorescence peaks were found in all fractions. Protein-like fluorescence peaks existed in HON may indicate that microbial activity was severely in Lake Hongfeng. There was a significant relationship between fluorescence intensities and specific UV absorbance at 254 nm for those DOM fractions, suggesting their similar luminescence characteristics. The values of fluorescence index (f450/500) indicated that hydrophobic fractions may derive from terrestrial sources, and the hydrophilic fractions from microbial and terrestrial origins. Those results suggest that there were inter-relationships between molecular weight, fluorescence and absorbance characteristics, and also subtle consistencies between the hydrophilic and hydrophobic properties and the sources for these 6 fractions from Lake Hongfeng.WANG Liying WU Fengchang ZHANG Runyu LI Wen LIAO Haiqing 2009Journal of Environmental Sciences2009,21,5:61
2Phosphorus speciation in the sediment profile of Lake Erhai, southwestern China: Fractionation and ^(31)P NMR显示文摘The distribution characteristics of phosphorus(P) forms in the sediment profile of Lake Erhai,in southwestern China has been investigated by sequential extraction and 31P nuclear magnetic resonance spectroscopy(NMR) of NaOH extracts to understand P dynamics and its potential contribution to lake eutrophication.Contents of P fractions varied in the order of NH4Cl extracted P(NH4ClP) < bicarbonate-dithionite extracted P(BD-P) < HCl-P,Residual-P < NaOH extracted P(NaOH-P).The highly available NH4Cl-P represented less than 1% of total P(TP).BD-P and NaOH extracted reactive P(NaOH-rP) averaged 39%,while the ratio of Fe/P was higher than 15,indicating low P release from the sediments under permanent oxic condition.The less bio-available HCl-P,NaOH extracted nonreactive P(NaOH-nrP) and residual-P contributed 61% of TP.Regression analysis revealed that BD-P,NaOH-rP and HCl-P were positively correlated with the contents of Fe and Mn,Al and Fe,and Ca,respectively.The investigation of P compound groups in NaOH extracts by 31 P NMR showed that ortho-P and monoester-P were the largest two constituents of the P pool,followed by diester-P,phosphonate and pyro-P.A comparison of vertical variations of P groups in the sediment profile suggested that these compounds were involved in the P recycling to different extents in Lake Erhai.In particular,the lake exhibits high potential for labile P release from the surface sediments,which should be taken into consideration even after the outsourced P runoff ceased.Runyu Zhang Liying Wang Fengchang Wu Baoan Song 2013Journal of Environmental Sciences2013,25,6:7

4Influence of Indian Ocean Dipole on Tropical Cyclone Activity over Western North Pacific in Boreal Autumn显示文摘In this study, we investigated the influence of the Indian Ocean Dipole (IOD) on the interannual variability of tropical cyclone (TC) activity over the western North Pacific (WNP) during autumn (September November) from 1961 2015. We found the number of TCs making landfall in China to be significantly negatively correlated with the IOD index, which can be attributed to shifts in the location of TC formation together with the abnormal steering flow at 500 hPa. During negative IOD autumns, TC genesis regions move obviously westward due to the westward retreat of the WNP monsoon trough. The TC activity is remarkably enhanced near South China coastal areas, which is due to a contiguous 500-hPa subtropical ridge. In contrast, during positive IOD autumns, TC genesis positions obviously shift eastward and more TCs tend to exhibit recurvature around 130 E or a westward path south of 15 N led by an equatorward movement of the 500-hPa subtropical ridge with a break near 125 E. In our examination of large-scale circula- tion, we found a pair of equator-symmetric anticyclones in the lower troposphere resulting from variations in the large-scale Walker circulation induced by the anomalous sea surface temperature (SST) associated with a positive IOD. The resulting Philippines anti- cyclonic anomalies are closely related to the variability of the monsoon trough over the WNP region. Furthermore, the variations in the steering flow can be explained by the suppressed (enhanced) convective activities around the Philippines and the weakened (strengthened) local meridional circulation over East Asia in positive (negative) IOD years.ZHOU Qun WEI Lixin ZHANG Runyu 2019Journal of Ocean University of China2019,18,4:6

7Temporal and spatial variations of low-molecular-weight organic acids in Dianchi Lake, China显示文摘Low-molecular-weight organic acids (LMWOAs) in eutrophic lake water of Dianchi, Southwestern China Plateau were investigated diurnally and vertically using ion chromatography. Two profiles (P1 and P2) were studied due to the difference of hydrochemical features. Lactic, formic, pyruvic and oxalic acid were detected as major components at P1 and P2 which were on average 7.98 and 6.53 μmol/L, respectively, corresponding to their proportions of 2.68% and 2.48% relative to DOC. Pyruvic acid was regarded as the uppermost species at P1 and P2, reaching up to 3.82 and 3.35 μmol/L and accounting for 47.9% and 51.3%, respectively, in individual TOA. Although humus were of biogenetic production at both sites, the significant negative correlation between diurnal variations of TOAs, fluorescence intensity (FI) of protein-like components and humic-like components at P1 indicated LMWOAs were greatly originated from bacterioplankton excretion and degradation. However, correlations between diurnal variations of humic-like FI and physicochemical parameters demonstrated algal origination of LMWOAs at P2. Although content of humus was high, TOA at P2 was 1.45 μmol/L lower than that at P1, due to the co-influence of more intense photo-oxidation and aggregation at P2. Therefore, TOAs exhibited quite opposite diurnal variation trends of increasing-decreasing and decreasing-increasing at P1 and P2, respectively. Except for impact of solar radiation, bacterial decomposition and assimilation rendered shifts of maximal LMWOAs along water column at P1. Covering with massive algae, UV rays penetrated shallower depth that LMWOAs assembled in surface layer water before 18:00 at P2 and represented decreasing profiles.Min Xia Fengchang Wu Runyu Zhang Liying Wang XinqingLi Rongsheng Huang 2011Journal of Environmental Sciences2011,23,8:4

9A Particle Filter Based Compressive Sensing Method for Tracking Moving Wideband Sound Sources显示文摘Tracking moving wideband sound sources is one of the most challenging issues in the acoustic array signal processing which is based on the direction of arrival(DOA) estimation. Compressive sensing(CS) is a recent theory exploring the signal sparsity representation, which has been proved to be superior for the DOA estimation. However, the spatial aliasing and the offset at endfire are the main obstacles for CS applied in the wideband DOA estimation. We propose a particle filter based compressive sensing method for tracking moving wideband sound sources. First, the initial DOA estimates are obtained by wideband CS algorithms. Then, the real sources are approximated by a set of particles with different weights assigned. The kernel density estimator is used as the likelihood function of particle filter. We present the results for both uniform and random linear array. Simulation results show that the spatial aliasing is disappeared and the offset at endfire is reduced. We show that the proposed method can achieve satisfactory tracking performance regardless of using uniform or random linear array.Juan Wei Fengli Yue Runyu Li Wenjing Wang Dan Gao 2018China Communications2018,15,5:2

11Enhancing photovoltaic performance via aggregation dynamics control in fused-ring electron acceptor显示文摘A new fused-ring electron acceptor FNIC3 with dynamics controlled aggregation behavior was synthesized.FNIC3 shows strong absorption in 600–900 nm,HOMO/LUMO energy levels of−5.59/−4.04 eV,and electron mobility of 1.2×10^(−3) cm^(2) V^(−1) s^(−1).The aggregation of FNIC3 shows strong dependency on film formation time.Prolongation of film formation time promotes the crystallization of FNIC3,leading to improved crystallinity and enlarged aggregate sizes.Aggregation of FNIC3 significantly influences the photovoltaic device parameters.Appropriate aggregation red-shifts the absorption and improves the mobilities of the blend,which contributes to high photocurrent and fill factor thus high power conversion efficiency(PCE).Overaggregation leads to increased nonradiative energy loss and insufficient charge generation,resulting in decreased open-circuit voltage and short-circuit current density.The blends based on PM6:FNIC3 fabricated under proper film formation time exhibit a PCE of 12.3%,higher than those fabricated under short and long film formation time(10.0–10.5%).Jiayu Wang Runyu Zhu Shijie Wang Yawen Li Boyu Jia Jiadong Zhou Peiyao Xue Susanne Seibt Yuze Lin Zengqi Xie Wei Ma Xiaowei Zhan 2021Aggregate2021,2,3:1

17Signaling pathways in vascular function and hypertension:molecular mechanisms and therapeutic interventions显示文摘Hypertension is a global public health issue and the leading cause of premature death in humans.Despite more than a century of research,hypertension remains difficult to cure due to its complex mechanisms involving multiple interactive factors and our limited understanding of it.Hypertension is a condition that is named after its clinical features.Vascular function is a factor that affects blood pressure directly,and it is a main strategy for clinically controlling BP to regulate constriction/relaxation function of blood vessels.Vascular elasticity,caliber,and reactivity are all characteristic indicators reflecting vascular function.Blood vessels are composed of three distinct layers,out of which the endothelial cells in intima and the smooth muscle cells in media are the main performers of vascular function.The alterations in signaling pathways in these cells are the key molecular mechanisms underlying vascular dysfunction and hypertension development.In this manuscript,we will comprehensively review the signaling pathways involved in vascular function regulation and hypertension progression,including calcium pathway,NO-NOsGC-cGMP pathway,various vascular remodeling pathways and some important upstream pathways such as renin-angiotensin-aldosterone system,oxidative stress-related signaling pathway,immunity/inflammation pathway,etc.Meanwhile,we will also summarize the treatment methods of hypertension that targets vascular function regulation and discuss the possibility of these signaling pathways being applied to clinical work.Jun Ma Yanan Li Xiangyu Yang Kai Liu Xin Zhang Xianghao Zuo Runyu Ye Ziqiong Wang Rufeng Shi Qingtao Meng Xiaoping Chen 2023Signal Transduction and Targeted Therapy2023,8,5:1
