Wireless power transfer (WPT) is a possible alternative to batteries for supplying smart sensors. It often described as "greener" because it avoids the use of batteries. However, this claim usually lacks proper assessment environmental impacts WPT and particularly questionable given poor efficiency wirelessly transmitting over few meters distance.

Although multiple forms of dimers have been described for GPCR, their dynamics and function are still controversially discussed field. Fluorescence microscopy allows GPCR to be imaged within native context; however, a key challenge is site-specifically incorporate reporter moieties that can produce high-quality signals upon formation dimers. To this end, we propose supramolecular sensor approach detect agonist-induced dimer μ-opioid receptors (μORs) at the surface intact cells. With...

Logs are widely used in modern software system management because they often the only data accessible that record events at runtime. In recent years, of ever-increasing log size, mining techniques utilized to help developers and operators conduct reliability management. A typical log-based procedure is first parse messages their unstructured format; apply on parsed logs obtain critical behavior information. Most existing research studies focus offline parsing, which need batch mode. However,...
