In Rocky Mountain National Park (RMNP), aspen (Populus tremuloides Michx.) has been observed to be declining on elk (Cervus elaphus nelsoni) winter range for many decades. To support elk management decisions, the SAVANNA ecosystem model was adapted to explore interactions between elk herbivory and aspen dynamics. The simulated probability of successful vegetative regeneration for senescent aspe...
We present the first broadband 0.3–25.0 keV X-ray observations of the bright ultraluminous X-ray source (ULX) Holmberg II X-1, performed by NuSTAR, XMM-Newton, and Suzaku in 2013 September. The NuSTAR data provide the first observations of Holmberg II X-1 above 10 keV and reveal a very steep high-energy spectrum, similar to other ULXs observed by NuSTAR to date. These observations further demon...
By applying a two-step statistical downscaling technique to four climate models under different future emission scenarios, we produced future projections of the daily precipitation and the maximum and minimum temperatures over the Spanish region of Aragón. The reliability of the downscaling technique was assessed by a verification process involving the comparison of the downscaled reanalysis da...

Dynamic reliability explicitly handles the interactions between the stochastic behavior of system components and the deterministic behavior of process variables. However, its industrial level applications are still limited, notably due to the inherent complexity of the theory and the lack of a generic modeling framework. The increased use of digital-based systems has also introduced additional ...
BACKGROUND The prevalence of hepatitis C virus (HCV) infection in Egypt is the highest in the world, yet the total economic burden has not been quantified. Improved understanding of costs and the impact of treatment strategies will provide for better allocation of resources to reduce HCV disease and economic burden. AIM A modelling approach was used to quantify the current HCV-infected popula...
OBJECTIVE To assess if transcranial direct current stimulation (tDCS) produces a temperature change at the skin surface, if any change is stimulation polarity (anode or cathode) specific, and the contribution of passive heating (joule heat) or blood flow on such change. MATERIAL AND METHODS Temperature differences (ΔTs) in an agar phantom study and an in vivo study (forearm stimulation) inclu...
The magnitude of future climate change depends substantially on the greenhouse gas emission pathways we choose. Here we explore the implications of the highest and lowest Intergovernmental Panel on Climate Change emissions pathways for climate change and associated impacts in California. Based on climate projections from two state-of-the-art climate models with low and medium sensitivity (Paral...
Identifying the areas at risk of ecosystem transformation and the main contributing factors to the risk is essential to assist ecological adaptation to climate change. We assessed the risk of ecosystem shifts in China using the projections of four global gridded vegetation models (GGVMs) and an aggregate metric. The results show that half of naturally vegetated land surface could be under moder...
Abstract Hybrid Renewable Energy System is a very good solution to the energy deficit encounter in developing countries. The paper presents optimal design of hybrid renewable system regarding technical aspect that Loss Power Supply Probability (LPSP), economic Cost Electricity (COE) and Net Present (NPC) environmental Total Greenhouse gases emission (TGE) aspects using multi-objective Particle ...
