17β-estradiol (E2) has been shown to have neuroprotective effects in different central nervous system diseases. The mechanisms underlying estrogen neuroprotection in spinal cord injury (SCI) remain unclear. Previous studies have shown that autophagy plays a crucial role in the course of nerve injury. In this study, we showed that E2 treatment improved the(More)
This paper presents the experimental validation of a multiple mobile robot system with human-in-the-loop coordination. It has been proposed that the control framework for networked autonomous robots can be augmented by artificial functions for task abstraction, so that a human operator is able to operate a group of robots remotely. By utilizing the(More)
AlGaN/GaN metal-oxide-semiconductor high electron mobility transistors (MOS-HEMTs) using La2O3 as gate oxide by electron-beam evaporated have been investigated and compared with the regular HEMTs [1]. The La2O3 thin film achieved a good thermal stability after 200°C, 400°C and 600°C post-deposition annealing due to its high binding energy (835.7 eV)(More)
This paper presents system framework and control algorithm for a human operator to remotely teleoperate a group of mobile robots over a network with time-varying delays. By utilizing the task-space technique adopted from control of redundant robotic manipulator, a human operator is able to command the task abstraction of a multi-robot system under the(More)
The thermal stability and reliability of AlGaN/GaN high electron mobility transistors (HEMTs) on Si substrates with a 2 μm-thick copper interconnection (Cu-INTC) metal were evaluated. The use of metallic copper as a conducting metal has the advantages of higher thermal conductivity, low cost and low sheet resistance. For comparison, traditional gold metal(More)
A decentralized bilateral teleoperation system is studied in this paper by using estimators with task abstraction. There is only a part of mobile robots in the multi-robot system can receive the human command via the master robot located in the local side. By exchanging information through a undirected and connected graph, mobile robots in the network have(More)
