The 3D Water Chemistry Atlas is an intuitive,open source,Web-based system that enables the three-dimensional(3D)sub-surface visualization of ground water monitoring data,overlaid on the local geological model(formation and aquifer strata).This paper firstly describes the results of evaluating existing virtual globe technologies,which led to the decision to use the Cesium open source WebGL Virtual Globe and Map Engine as the underlying *** it describes the backend database and search,filtering,browse and analysis tools that were developed to enable users to interactively explore the groundwater monitoring data and interpret it spatially and temporally relative to the local geological formations and aquifers via the Cesium *** result is an integrated 3D visualization system that enables environmental managers and regulators to assess groundwater conditions,identify inconsistencies in the data,manage impacts and risks and make more informed decisions about coal seam gas extraction,waste water extraction,and water reuse.

数百万年来,大型、中型和小型陆地哺乳类动物的灭绝速度大致相等。然而,从10万年前的欧亚大陆、5万年前的澳洲大陆,以及1.5万年前的美洲大陆开始,大型哺乳动物的灭绝速度明显加快了(图A)。一项研究显示,这一变化趋势与包括直立人(Homo e... 详细信息

数百万年来,大型、中型和小型陆地哺乳类动物的灭绝速度大致相等。然而,从10万年前的欧亚大陆、5万年前的澳洲大陆,以及1.5万年前的美洲大陆开始,大型哺乳动物的灭绝速度明显加快了(图A)。一项研究显示,这一变化趋势与包括直立人(Homo erectus)、尼安德特人(Homo neanderthalensis).以及智人(Homo sapies)在内的古人类(hominin spedes)向各个大陆的迁徙行为相吻合。

To date,the clinical use of functional near-infrared spectroscopy(NIRS)to detect cerebral ischemia has been largely limited to surgical settings,where motion artifacts are *** this study,we present novel techniques to address the challenges of using NIRS to monitor ambu-latory patients with kidney disease during approximately eight hours of hemodialysis(HD)*** with end-stage kidney disease who require HD are at higher risk for cognitive impairment and dementia than age-matched *** studies have suggested that HD-related declines in cerebral blood flow might explain some of the adverse outcomes of HD ***,there are currently no established paradigms for monitoring cerebral per-fusion in real-time during HD *** this study,we used NIRS to assess cerebral hemo-dynamic responses among 95 prevalent HD patients during two consecutive HD *** observed substantial signal attenuation in our predominantly Black patient cohort that required probe *** also observed consistent motion artifacts that we addressed by devel-oping a novel NIRS methodology,called the HD cerebral oxygen demand algorithm(HD-CODA),to identify episodes when cerebral oxygen demand might be outpacing supply during HD *** then examined the association between a summary measure of time spent in cerebral deoxygenation,derived using the HD-CODA,and hemodynamic and treatment-related *** found that this summary measure was associated with intradialytic mean arterial pressure,heart rate,and volume *** studies should use the HD-CODA to implement studies of real-time NIRS monitoring for incident dialysis patients,over longer time frames,and in other dialysis modalities.
