title: Vertical distribution of total and particulate 234Th, particulate organic carbon (POC) and nutrients with their physical forcings (temperature, salinity, fluorescence-based Chl a)

description: Temperature, salinity, fluorescence-based Chl a were accessed from sensors attached to a Seabird 911 conductivity-temperature-depth (CTD); Total 234Th was precipitated by using the small-volume (4 L) MnO2 co-precipitation method (Benitez-Nelson et al., 2001; Cai et al., 2006). Particulate 234Th and POC were filterd by quartz microfiber (QMA) filters (25 mm diameter, 1.0 μm pore size) as particulate samples following method described in the JGOFS cookbook (Knap et al., 1996); the activity of 234Th was determined by a gas-flow proportional low-level RISØ beta counter (Model GM-25-5). Precipitation efficiency was determined by ICP-MS. Nutrients were analysed onboard using a Four-channel Continuous Flow Technicon AA3 Auto-Analyzer (Bran-Lube GmbH). The detection limits for both N+N (nitrate plus nitrite, termed as dissolved inorganic nitrogen, DIN) and SRP (soluble reactive phosphate) were 0.03 μmol L-1.

title: A dataset of A modified formula of thermal focal length for lamp pumping Cr,Er:YSGG crystal with high performance 2.79 μm laser

description: We demonstrate the laser and thermal properties on the four Cr,Er:YSGG crystal rods with different diameters from 3 to 6 mm. A maximum pulse energy 1261 mJ operated at 5 Hz and 2.79 μm is obtained on the rod of 4 mm diameter, corresponding to electrical-to-optical efficiency of 1.53% and slope efficiency 1.82%, respectively. Combining with the electrical-to-optical efficiency and thermal distribution, the formula of the thermal focal length is modified further. The simulation results of the thermal focal length for four crystals with different diameters are in good consistence with the measurement values, suggesting the revised formula is accurate and effective to calculate the thermal focal length.

title: Spectroscopy and LD end-pumped high power 2.79 μm CW laser from an Er:LuYSGG mixed crystal
title: Er:LuYSGG激光晶体的光谱及激光性能的数据集

description: We report on the spectroscopic and laser performance of a novel 30 at.% Er:LuYSGG mixed crystal grown by Czochralski method. The XRC result shows the crystal has a high crystalline quality. A strong absorption peak is located at 966 nm with a FWMH of about 11 nm. The lifetimes of the upper 4I11/2 and lower 4I13/2 levels are 1.91 ms and 6.53 ms, respectively. A maximum output power of 909 mW with LD end-pumping is achieved, corresponding to optical-to-optical conversion efficiency of 18.1% and slope efficiency of 21.6%. The laser wavelength of 2794 nm and beam quality factors Mx2/My2 of 1.78/1.83 are displayed. These results indicate that Er:LuYSGG mixed crystal is a promising gain medium for 2.8 μm laser.

title: Phenotypic variations of wheat cultivars from the North China Plain in response to cadmium stress and associated single nucleotide polymorphisms identified by a genome-wide association study
title: 镉胁迫下华北小麦群体苗期表型变异及关联新颖分子标记挖掘

description: A diverse panel of 132 wheat cultivars from the North China Plain was collected and evaluated in terms of their phenotypic variations in response to Cd stress, and subject to a genome-wide association study (GWAS) to identify single nucleotide polymorphisms (SNPs) associated with the phenotypic variations at the seedling stage. Significant phenotypic variations with high heritability were observed among the wheat cultivars under 40 μM Cd for the studied traits, including root length (RL), shoot length (SL), root and shoot dry biomass (RDW and SDW), root and shoot Cd content (RCD and SCD), and Cd translocation factor (TF). The mixed linear model-based association analysis detected 17 novel significant marker-trait associations (MTAs), four of which were significant at a genome-wide scale. Most of the significant MTAs controlled TF and explained 17.17% to 26.47% of the phenotypic variations.

title: Investigation of defect, mechanical, thermal properties and refractive index on an Er:LuYSGG mixed laser crystal

description: We investigate the defect, mechanical, thermal properties, and refractive index of Er:LuYSGG mixed crystal grown by the Czochralski method. The chemical etching pit patterns present a regular tetrahedron, which consists well with the corresponding atomic arrangement schematics. The Mohs hardness is obtained to be 6.60. The thermal expansion coefficient and the thermal conductivity along &lt;111&gt; crystallographic orientation are achieved to be 7.91×10-6 K-1 and 3.423 W m-1 K-1, respectively, indicating the Er:LuYSGG has a relatively high damage threshold. Based on the measured values of refractive index, the Sellmeier equation is fitted and the refractive index curve in the range of 400-3000 nm is displayed. All these results are of great significance for the further research and laser application of Er:LuYSGG crystal.

title: Growth, physicochemical and optical properties of LuYSGG garnet single crystal
title: Growth, physicochemical and optical properties of LuYSGG garnet single crystal

description: We investigate the physical and chemical properties of a Lu1Y2Sc2Ga3O12 (LuYSGG) single crystal with high quality grown by the Czochralski (Cz) method. The XRC result shows the crystal has high crystalline quality and the lattice constant is calculated to be 12.4253 Å, and the lattice constant value could be adjusted by changing the ratio of Lu and Y. The dislocation density on the (111)-crystalline face is achieved to be about 200 cm-2. The Mohs hardness is obtained to be 6.86. The surface roughness (Ra) of the polished LuYSGG wafer is only 0.23 nm. The thermal expansion coefficient and the thermal conductivity are measured to be 8.5×10-6 K-1 and 4.79 W m-1 K-1, respectively, indicating the LuYSGG has better thermal properties. In addition, the Sellmeier equation is fitted by the measured refractive indices at a few distinct wavelengths using the method of minimum deviation angle, and the refractive index curve in the range of 400-3000 nm is displayed. The maximum phonon energy of LuYSGG crystal is determined to be 880.7 cm-1. All the obtained results can provide useful reference parameters for the further investigation of LuYSGG crystal as epitaxial magneto-optical thin film substrate and laser host.

title: Arabidopsis and rice showed a distinct pattern in ZIPs genes expression profile in response to Cd stress
title: 拟南芥和水稻ZIPs基因的不同镉胁迫响应模式

description: This study revealed a distinct pattern in ZIPs genes expression regulation in response to Cd stress between Arabidopsis and rice. Arabidopsis mainly up-regulated root ZIPs genes, while rice mainly up-regulated shoot ZIPs genes. Interestingly, some genes like AtIRT3, AtZIP5, AtZIP12, OsIRT1 and OsZIP1 showed contrary expression regulation when subject to the tested Cd stress. Three genes, AtIRT1, OsZIP1 and OsZIP3, conferred an increased sensitivity to Cd stress and more Cd accumulation when expressed in yeast cells, implying a role in direct Cd uptake in plants.

title: Light absorption properties and molecular compositions of water-soluble and methanol-soluble organic carbon emitted from wood pyrolysis and combustion
title: 木材热解和燃烧得到的水溶性和甲醇溶性有机碳的光吸收特性和分子组成

description: Primary organic aerosol (POA) is produced by combustion and pyrolysis of fir wood in a tube furnace under different heating atmospheres and temperatures. Dissolved organic carbon was obtained by extracting POA with methanol and pure water. The absorption spectra, functional groups, and molecular composition of the dissolved organic carbon were measured and analyzed. The results found that dissolved organic carbon under nitrogen conditions had higher light absorption properties than dissolved organic carbon under air conditions and that methanol-soluble organic carbon had a higher light absorption capacity than water-soluble organic carbon. These results are attributed to the higher molecular weight, unsaturation, and modified aromaticity of methanol-soluble organic carbon compared to water-soluble organic carbon; and dissolved organic carbon under nitrogen has a higher molecular weight, unsaturation, and modified aromaticity than that under air. By the correlation between the mass absorption efficiency values at 365 nm and the molecular properties, the positive and negative correlation between the absorption properties of dissolved organic carbon and its molecular properties was established, which is helpful to understand the essential reasons for the changes in the absorption properties of POA at the molecular level.
