Cosmological constraints from current and upcoming galaxy cluster surveys are limited by the accuracy of mass calibration. In particular, optically identified clusters prone to selection effects that can bias weak lensing We investigate stacked signal associated with selected clusters, using redMaPPer algorithm in Buzzard simulations as a case study. find at given halo mass, residuals richness positively correlated. As result, for selection, is biased high compared what we would expect...
The direct cross-couplings of diaryl sulfoxides with aryl bromides via C-S bond cleavage could be readily accomplished using nickel(II) as the catalyst, 1,2-bis(diphenylphosphino)ethane (dppe) ligand, and magnesium turnings reducing metal in THF, leading to corresponding biaryls moderate good yields. reaction exhibited a broad substrate scope applied gram-scale synthesis. "one-pot" reaction, which avoids utility presynthesized moisture-labile organometallic compounds, is operationally simple...
An efficient Sonogashira coupling of a heterocyclic phosphonium salt with terminal alkyne via C–P bond cleavage was developed. The reactions proceeded smoothly in the presence palladium catalyst, copper(I) iodide, and N,N-diisopropylethylamine (DIPEA) N-methyl-2-pyrrolidone (NMP) at 100 °C for 12 h, producing corresponding alkynyl-substituted pyridine, quinoline, pyrazine, quinoxaline moderate to good yields wide substrate scope broad functional group tolerance. In addition, gram-scale...
Low-carbon development (LCD) in China has become the critical measure to achieve sustainable and handle climate change. This investigation evaluates 30 provincial regions’ LCD quality from dimensions of low-carbon (LC) economy, resources utilization, LC environment, society. According integrated weights combined subjective identified through best–worst method (BWM) objective attained anti-entropy weight (AEW) method, top five sub-criteria 2021 were coal consumption relative total primary...
The responses of fine root mass, length, production and turnover to the increase in soil N availability are not well understood forest ecosystems. In this study, sequential core ingrowth methods were employed examine (≤1 mm) standing biomass, length density (RLD), specific (SRL), biomass rate fertilization (10…−2 year−1) Larix gmelinii (larch) Fraxinus mandshurica (ash) plantations. significantly reduced from 130.7 103.4 g m−2 ash, but had no significant influence larch (81.5 control 81.9...
ABSTRACT Counts of galaxy clusters offer a high-precision probe cosmology, but control systematic errors will determine the accuracy this measurement. Using Buzzard simulations, we quantify one such systematic, triaxiality distribution identified with redMaPPer optical cluster finding algorithm, which was used in Dark Energy Survey Year-1 (DES Y1) cosmology analysis. We test whether selection biases clusters’ shape and orientation find that it only orientation, preferentially selecting their...
Many invasive alien plant species are clonal and can greatly propagate spread through integration (sharing resources between connected ramets) in heterogeneous variable environments. Here, we tested whether water variability influences of consequently facilitates their growth dominance a native community. We selected four typical China. Connected (with integration) disconnected (without fragments were established either under constant watering or condition an experimental community...
Climate change and human activities have continuously decreased productivity, carbon storage soil fertility of global plantations under continuous planting. However, this situation can be largely reversed through appropriate planting density thinning management. We evaluated the effects initial selective management on biomass accumulation stocks in different plantation compartments, stand stages a chronosequence evergreen (Cunninghamia lanceolata) typical hilly mountainous areas Jiangxi...
An efficient nickel-catalyzed, iron-mediated hydrofluoroalkylation of alkynes with bromodifluoroacetate or perfluoroalkyl iodide, which proceeded smoothly to give fluoroalkylated ( Z )-alkenes high stereocontrol (up 99 : 1 / E ), was developed.
ABSTRACT We present an investigation into a hitherto unexplored systematic that affects the accuracy of galaxy cluster mass estimates with weak gravitational lensing. Specifically, we study covariance between lensing signal, ΔΣ, and ‘true’ number count, Ngal, as measured within spherical volume is void projection effects. By quantifying impact this on calibration, work reveals significant source uncertainty. Using MDPL2 simulation galaxies traced by SAGE semi-analytic model, measure...
The dynamics of herb diversity, distribution patterns and interspecific associations dominant herbs in natural forests at three growing stages a city-suburb-exurb context Wuhan City were studied using fixed plot.The results show that the composition, diversity indices, mean total richness gradually increased with gradient.Codominant species across temporal Qinglong Mountain stable, however, there remarkable changes city-suburb context.Qinglong (exurb context) had densest codominant herbs,...
Abstract Data from three seed orchards (Chongyang, Zhangle and Laoshan) Lintian forest were used to study pollination characteristics, level, pollen ovule production in Chinese fir. The results show that male female cones have their own distribution patterns within crowns. Male are located the middle top bottom part of crown. Because lower density trees orchard than a stand, distributed over entire crown trees. fir appear be very well adapted for wind as mechanism. There is no difference...
The effect of maternal mowing on seed traits an invasive weed, Erigeron annuus, in farmland was discussed by comparing plants with intact (no-mowing) plants.The resulted the decrease mass, achene size, pappus length and germination percentage increase variation length, dispersal distance non-uniformity.To some extent, individuals suffered might accelerate environmental adaptation through these variations.Our study indicated mean will restrain growth reproduction weed E. annuus.However, it...
