WiFi fingerprint-based indoor localization has received considerable attention to enjoy higher deployment practicability, because of the ubiquitous APs (Access Points) and WiFi-enabled smart devices. In existing WiFi-based localization methods, smart mobile devices consume quite a lot of power as WiFi interfaces need to be used for frequent AP scanning(More)
In Wireless Sensor Networks (WSNs) a multitude of location-dependent applications have been proposed recently, which is very intriguing for researchers to discover and design more accurate and cost-effective localization algorithms. In an isotropic networks, the Euclidean distance between a pair of nodes may not correlate closely with the hop count between(More)
Platinum black coating can effectively improve the performance of MEAs (microelectrodes array) in neural signal transduction, though its lack of adhesion strength and durability tampers its usage in long term experiments. Here a new method of composite electrodeposition provides highly adhesive platinum black coating that enables MEAs for a month’s long(More)
We report the study of several inhibitors on alanine aminotransferase (ALT) enzyme using sequential online capillary electrophoresis (CE) assay. Using metal ions (Na(+) and Mg(2+)) as example inhibitors, we show that evolution of the ALT inhibition reaction can be achieved by automatically and simultaneously monitoring the substrate consumption and product(More)
Along with the fast development of sensor hardware, traditional scalar sensor nodes are now provided with both multimedia and mobility functions. By observing this emerging combination of these two functions into traditional wireless sensor networks (WSNs), we take the opportunity in this paper to highlight a subset of WSNs, which we name as “Mobile(More)
OBJECTIVE Although various kinds of optrodes are designed to deliver light and sense electrophysiological responses, few have a tightly closed optical delivering site or electrical recording site. The large space between them often blurs the stimulation location and light intensity threshold. APPROACH Based on an optical fiber, we develop an optrode(More)
