For survivability evaluation of command information system, it is important to build efficient survivability evaluation indexes. To solve the problems of unclear index classification, weak index operability and incomplete index content, a threelevel structure of survivability evaluation indexes is proposed for command information system under complex electromagnetic environment. © 2011 IEEE.

Simulations were made to obtain the design strategy of smoke control in consideration of the atrium features of a university library in Beijing through fire scene set-up, fire severity design, smoke control analyses, and evacuation practice. The results show that the inner atrium fire control system design should consider the influence of the moving height, exhaust smoke level, fire detection and danger alarm, and that a large full-height automatic control gear can efficiently prevent smoke invasion and protect personal safety during evacuation.

Background and Aim: Tanshione IIA (TSN) is the major active component of Salvia miltiorrhiza, a traditional Chinese Medicine. TSN protects against antioxidant-induced liver injury, although the exact mechanism is not well understood. Materials and Methods: In this study, the protective effects of TSN was examined by enzyme-linked immunosorbent assay (ELISA) and histochemistry of several cytokines. Results: TSN is found to significantly reduce plasma alanin aminotransferase and aspartate amino transferase levels in mice with concanavalin A-induced immune-mediated liver injury. TSN increases T lymphocyte subset CD3+, CD4+ and CD8+ ratios. Also, TSN significantly reduces inflammatory cytokines, including interleukin-2, interleukin-4, interferon-gamma and tumor necrosis factor alpha, while elevates anti-inflammatory cytokine, interleukin-10. Conclusions: TSN may provide a potential drug candidate for liver injury therapeutics. © 2010 Informa UK Ltd. Source

In order to enhance the test efficiency of information security system, analysis of the attributes of attackers, offensive rules and offensive planning products is very important. Based on the study of attackers' individual attributes, attackers' task-oriented polymerization rules are analyzed and described by polymer operator, mobile operator and splitting operator in the paper. Then an attacker's behavior planning algorithm is prompted. It contains the planning steps, behavior and dynamic evolution of the planning process. Finally application of an example is demonstrated to prove the feasibility of the algorithm. Source

Beijing’s 2015 World Robot Conference introduced three robots that specialize in reconnaissance, armed attack, and disposing small explosives – toy-sized ones that can very well coordinate with one another while in battle. The robots debuted amid growing global threats of terrorist action and following the series of coordinated attacks in numerous areas in Paris, France. Wu Yanpeng, Harbin-based HIT Robot Group engineer and developer of the three robots, explained each one’s capabilities. The reconnaissance robot – known as scout – takes field detection on using sensor or camera. Once it senses a suspicious explosive item or chemical, it transmits information to headquarters for further probe. The small explosive ordnance disposal robot as well as the armed attack robot – basing on the data analysis and need to evacuate – will begin their mission: the small EOD robot will move and defuse the bomb, while the attacker robot will hit target from a long distance using its minor-caliber weapons, rifles, and grenade launchers. If the situation is more complex than the small EOD robot can handle, the office-based bomb experts will produce a solution, added Wu. A soldier working alone can carry on his back the 12-kilogram or about 26 pounds small EOD robot, made of industrial plastic and aluminum alloy. But the robots are seen to work not just for warfare, but also for simpler public security operations, firefighting, agriculture, and forestry. The set of robots is priced at around $230,000 or 1.5 million yuan, said HIT Robot Group sales manager Chen Deqiang. And it now has its fair share of buyers, according to the company, including the Beijing Municipal Public Security Bureau. China itself is on national alert due to terror threats in Xinjiang province as well as the rest of the nation following the deadly attacks in Paris. China police Chief Guo Shengkun, at a televised meeting, called on officials to stay on heightened alert and terrorism prevention. China, the world’s second biggest economy, leads the pack in marketing industrial robots with its share of a quarter of global sales. Service robots for homes and offices, however, were pinpointed to be the true opportunity for the market. "There are now fewer than 100,000 robots in Chinese families, not including vacuum cleaners," said Canbot CEO Liu Xuenan at an executive roundtable during the robot conference. Horizon Robotics head Yu Kai, on the other hand, estimated a greater role for the automated helpers in the future, predicting: “[E]ach person might have 10 robots.”
