Abstract The primary driver of the land carbon sink is gross productivity (GPP), absorption dioxide (CO 2 ) by plant photosynthesis, which currently accounts for about one-quarter anthropogenic CO emissions per year. This study aimed to detect variability using standardized evapotranspiration deficit index (SEDI). Sixteen countries in Middle East (ME) were selected investigate drought. To this ...

Simulation of Water Balance Components (WBCs) is import for sustainable water resources development and management. The Soil Assessment Tool (SWAT) a semi-distributed hydrological model to estimate the WBCs by forcing response unit (HRU) meteorological variables. developed simulates five viz. surface runoff, lateral flow, percolation, actual evapotranspiration soil at sub catchment level. To de...

A quantificação dos recursos hídricos disponíveis é fundamental para o seu gerenciamento adequado e a sustentação da qualidade de vida. Convencionalmente, as variáveis hidrológicas são estabelecidas por medições in situ , no entanto há escassez desses dados, tornando Sensoriamento Remoto (SR) uma alternativa atraente. O objetivo deste trabalho obter balanço hídrico em bacias hidrográficas parti...

Abstract. Streamflow is often the only variable used to evaluate hydrological models. In a previous international comparison study, eight research groups followed an identical protocol calibrate 12 models using observed streamflow of catchments within Meuse basin. current we quantify differences in five states and fluxes these process-based with similar performance, systematic comprehensive way...

network.” Since the Wi-Fi was still working, residents downloaded a telephony app onto their phones and used it to send urgent text messages. At one point, the system brought several residents together for a code in a dark room. By the glow of headlamps and bobbing flashlights, a resident began resuscitation while others prepared to place a central catheter. While Samad tried to sustain morale,...

What is it famous for? The Whitehead Institute is probably one of those places that's famous for being famous. But that's not to say it doesn't deserve its reputation. Despite its relatively small staff — only 15 scientists are on the faculty — the Whitehead has a publication record that puts it among the top research institutions in genetics and molecular biology. What's its focus? Work there ...

Abstract. Accurate high-resolution actual evapotranspiration (ET) and gross primary production (GPP) information is essential for understanding the large-scale water carbon dynamics. However, substantial uncertainties exist in current ET GPP datasets China because of insufficient local ground measurements used model constraint. This study utilizes a water–carbon coupled model, Penman–Monteith–L...

One of the great pleasures of working in a rapidly changing field is watching it grow and mature. With an auspicious beginning in the late 1960s, the field of AI in Education has evolved from a gleam in its founders' eyes to a well established discipline with an active scientific community that has produced an imposing literature. Now with more than three decades of experience under its belt, i...

BACKGROUND Computational models play an increasingly important role in the assessment and control of public health crises, as demonstrated during the 2009 H1N1 influenza pandemic. Much research has been done in recent years in the development of sophisticated data-driven models for realistic computer-based simulations of infectious disease spreading. However, only a few computational tools are ...

Abstract. Despite the importance of vegetation uptake atmospheric gaseous elemental mercury (Hg(0)) within global Hg cycle, little knowledge exists on physiological, climatic, and geographic factors controlling stomatal Hg(0) by tree foliage. We investigate controls foliar combining measurements 3569 foliage samples across Europe with data species' traits environmental conditions. To account fo...
