| 1 | Comparison of two remote sensing models for estimating evapotranspiration: algorithm evaluation and application in seasonally arid ecosystems in South Africa显示文摘Remote sensing tools are becoming increasingly important for providing spatial information on water use by different ecosystems. Despite significant advances in remote sensing based evapotranspiration(ET) models in recent years, important information gaps still exist on the accuracy of the models particularly in arid and semi-arid environments. In this study, we evaluated the Penman-Monteith based MOD16 and the modified Priestley-Taylor(PT-JPL) models at the daily time step against three measured ET datasets. We used data from two summer and one winter rainfall sites in South Africa. One site was dominated by native broad leaf and the other by fine leafed deciduous savanna tree species and C4 grasses. The third site was in the winter rainfall Cape region and had shrubby fynbos vegetation. Actual ET was measured using open-path eddy covariance systems at the summer rainfall sites while a surface energy balance system utilizing the large aperture boundary layer scintillometer was used in the Cape. Model performance varied between sites and between years with the worst estimates(R2<0.50 and RMSE>0.80 mm/d) observed during years with prolonged mid-summer dry spells in the summer rainfall areas. Sensitivity tests on MOD16 showed that the leaf area index, surface conductance and radiation budget parameters had the largest effect on simulated ET. MOD16 ET predictions were improved by:(1) reformulating the emissivity expressions in the net radiation equation;(2) incorporating representative surface conductance values;and(3) including a soil moisture stress function in the transpiration sub-model. Implementing these changes increased the accuracy of MOD16 daily ET predictions at all sites. However, similar adjustments to the PT-JPL model yielded minimal improvements. We conclude that the MOD16 ET model has the potential to accurately predict water use in arid environments provided soil water stress and accurate biome-specific parameters are incorporated. | Sebinasi DZIKITI Nebo Z JOVANOVIC Richard DH BUGAN Abel RAMOELO Nobuhle P MAJOZI Alecia NICKLESS Moses A CHO David C LE MAITRE Zanele NTSHIDI Harrison H PIENAAR | 2019 | Journal of Arid Land2019，11，4： | 4 |

| 4 | Acute ischaemic stroke interventions: large vessel occlusion and beyond显示文摘Care for acute ischaemic stroke is one of the most rapidly evolving fields due to the robust outcomes achieved by mechanical thrombectomy.Large vessel occlusion(LVO)accounts for up to 38%of acute ischaemic stroke and comes with devastating outcomes for patients,families and society in the pre-intervention era.A paradigm shift and a breakthrough brought mechanical thrombectomy back into the spotlight for acute ischaemic stroke;this was because five randomised controlled trials from several countries concluded that mechanical thrombectomy for acute stroke offered overwhelming benefits.This review article will present a comprehensive overview of LVO management,techniques and devices used,and the future of stroke therapy.In addition,we review our institution experience of mechanical thrombectomy for posterior and distal circulation occlusion. | Ahmad Sweid Batoul Hammoud Sunidhi Ramesh Daniella Wong Tyler D Alexander Joshua Harrison Weinberg Maureen Deprince Jaime Dougherty Dimitri Jean-Mickael Maamari Stavropoula Tjoumakaris Hekmat Zarzour Michael R Gooch Nabeel Herial Victor Romo David M Hasan Robert H Rosenwasser Pascal Jabbour | 2020 | Stroke & Vascular Neurology2020，5，1： | 2 |
