Reconfigurable Intelligent Surface Enabled Spatial Multiplexing with Fully Convolutional Network [PDF]
arXiv, 2022 Reconfigurable intelligent surface (RIS) is an emerging technology for future wireless communication systems. In this work, we consider downlink spatial multiplexing enabled by the RIS for weighted sum-rate (WSR) maximization. In the literature, most solutions use alternating gradient-based optimization, which has moderate performance, high complexity,

Machine Learning Models to Predict Inhibition of the Bile Salt Export Pump [PDF]
arXiv, 2020 Drug-induced liver injury (DILI) is the most common cause of acute liver failure and a frequent reason for withdrawal of candidate drugs during preclinical and clinical testing. An important type of DILI is cholestatic liver injury, caused by buildup of bile salts within hepatocytes; it is frequently associated with inhibition of bile salt transporters,

Tauroursodeoxycholic acid exerts anticholestatic effects by a cooperative cPKC alpha-/PKA-dependent mechanism in rat liver. [PDF]
, 2008 Objective: Ursodeoxycholic acid (UDCA) exerts anticholestatic effects in part by protein kinase C (PKC)-dependent mechanisms. Its taurine conjugate, TUDCA, is a cPKCa agonist.

Journal of British Surgery, 1993 Abstract Acid gastro-oesophageal reflux occurs when the lower oesophageal sphincter is incompetent, but oesophagitis caused by reflux of duodenal content implies incompetence of both the pyloric and gastro-oesophageal sphincters. The term ‘alkaline’ reflux oesophagitis was coined long before objective analysis was made-of bile in the ...

Approaching Globally Optimal Energy Efficiency in Interference Networks via Machine Learning [PDF]
arXiv, 2022 This work presents a machine learning approach to optimize the energy efficiency (EE) in a multi-cell wireless network. This optimization problem is non-convex and its global optimum is difficult to find. In the literature, either simple but suboptimal approaches or optimal methods with high complexity and poor scalability are proposed. In contrast, we
