This paper introduces a novel method for estimating the skeleton proportions of a human figure from monocular data. The proposed system will first automatically extract the key frames and recover the perspective camera model from the 2D data. The human skeleton proportions are then estimated from the key frames using the recovered camera model without posture re- construction. The proposed method is tested to be simple, fast and produce satisfactory results for the input data. The human model with estimated proportions can be used in future research involving human body modeling or human motion reconstruction.

In inverted perovskite solar cells (PScs),effective modification of the interface between the metalcathode and electron transport layer (ETL) is crucial forachieving high performance and stability. Herein, sulfonatedbathocuproine, commonly known as disodium bathocuproinedisulfonate (BcDS), was employed as a cathode buffer layerto address the interfacial issues at the [6,6]-phenyl-c61-butyricacid methyl ester (PcBM)/Ag interface. BcDS possesses theability to form coordinate bonds with Ag electrodes. Theutilization of the BcDS buffer layer enhanced the chargeextraction capability at the cathode interface whilesimultaneously achieving interfacial defect passivation,improving interfacial contact and increasing the built-in electricfield. consequently, a power conversion effic.ency (PcE) of25.06% was achieved. Furthermore, owing to the excellent filmforminguniformity of BcDS on PcBM, the stability of thedevice was also improved. After storage in dry air for morethan 2000 h, the device maintained 96% of its initial effic.ency. This work underscores the remarkable potential of tailoringcoordination groups to enhance charge extraction effic.ency at the ETL-cathode interface, unveiling a promising newfrontier in buffer layer development and performance optimization strategies for PScs.

cotton is the main economically important crop in Xinjiang,china,but soil salinization and shortage of water and nutrients have restricted its production.A field experiment was carried out in the salinity-affected arid area of Northwest china from 2018 to 2019 to explore the effects of nitrogen and water regulation on physiological growth,yield,water and nitrogen use effic.encies,and economic benefit of *** salinity levels were 7.7(SL)and 12.5 dS/m(SM).Drip irrigation was used with low,medium and adequate irrigation levels representing 60%,80%and 100%of cotton crop water demand,respectively,and three nitrogen applications,i.e.,206,275 and 343 kg/hm^(2),accounting for 75%,100%and 125%of local N application,respectively were *** multi-objective optimization based on spatial analysis showed that,at SL salinity,water use effic.ency(WUE),nitrogen use effic.ency(NUE),economic benefit and yield simultaneously reached more than 85%of their maxima at 379.18-398.32 mm irrigation and 256.69-308.87 kg/hm^(2).At SM salinity,WUE,yield and economic benefit simultaneously reached more than 85%of their maxima when irrigation was 351.24-376.30 mm and nitrogen application was 230.18-289.89 kg/hm^(2).NUE,yield and economic benefit simultaneously reached their maxima at 428.01-337.72 mm irrigation,and nitrogen application range was 222.14-293.93 kg/hm^(2).The plants at SL salinity had 21.58%-46.59%higher WUE rates,14.91%-34.35%higher NUE rates and 20.71%-35.34%higher yields than those at SM *** results are of great importance for the nutrient and water management in cotton field in the arid saline area.

The projected temperature and precipitation- change under different emissions scenarios using coupled Model Intercomparison Project Phase 5 models over the northwestern arid regions of china （NWAc） were ana- lyzed using the ensemble of three high-resolution dy- namical downscaling simulations： the simulation of the Regional climate Model version 4.0 （RegcM4） forced by the Beijing climate center climate System Model version 1.1 （Bcc_cSMI.1）; the Hadley centre Global en- vironmental Model version 3 regional climate model （HadGEM3-RA） forced by the Atmosphere-Ocean cou- pled HadGEM version 2 （HadGEM2-AO）; and the Weather Research and Forecasting （WRF） model forced by the Norwegian community Earth System Model （NorESM1-M）. Model validation indicated that the mul- timodel simulations reproduce the spatial and temporal distribution of temperature and precipitation well. The temperature is projected to increase over NWAc under both the 4.5 and 8.5 Representative concentration Path- ways scenarios （RcP4.5 and RcP8.5, respectively） in the middle of the 21 st century, but the warming trend is larger under the RcP8.5 scenario, Precipitation shows a signifi- cant increasing trend in spring and winter under both RcP4.5 and RcPS.5; but in summer, precipitation is pro- jected to decrease in the Tarim Basin and Junggar Basin. The regional averaged temperature and precipitation show increasing trends in the future over NWAc; meanwhile, the large variability of the winter mean temperature and precipitation may induce more extreme cold events and intense snowfall events in these regions in the future.
