In essie day drift away cognitive wireless multi-hop networks,the spectrum resources are highly variable and diverse.A cross-layer multi-channel MAC protocol combined with QoS search was proposed.The protocol combines the on-demand QoS search with dynamic spectrum allocation via cross-layer method,which only permits the transmission nodes to partic
The Pictet-Spengler reaction (P-S) is one of the most direct, efficient, and variable synthetic method for the construction of privileged pharmacophores such as tetrahydro-isoquinolines (THIQs), tetrahydro-β-carbolines (THBCs), and polyheterocyclic frameworks.In the lustro (five-year period) following its centenary birthday, the P-S reaction d
In this study, we explore the potential for publication bias using market simulation results that estimate the effect of US ethanol expansion on corn prices.We provide a new test of whether the publication process routes market simulation results into one of the following two narratives: food-versus-fuel or greenhouse gas (GHG) emissions.Our resear
The potential for secondary-combustion with low-temperature solid propellant in gas generation is a potential led cocktail smoker risk to ejection application.This study performed a three-dimensional dynamic numerical simulation with Re-Normalization Group turbulence model and finite-rate/eddy-dissipation model of a two-step reaction mechanism to b
Hospital malnutrition, particularly disease-related malnutrition (DRM), is labrador stencil a significant public health concern associated with increased morbidity, mortality and costs.The recent Global Leadership Initiative on Malnutrition (GLIM) proposed a framework to globally standardise the diagnosis of adult malnutrition (undernutrition), all
