Radio frequency (RF) energy transfer and harvesting techniques have recently become alternative methods to power the next generation wireless networks. As this emerging technology enables proactive energy replenishment of wireless devices, it is advantageous in supporting applications with quality of service (QoS) requirement. In this paper, we present an(More)
A “botnet” consists of a network of compromised computers controlled by an attacker (“botmaster”). Recently, botnets have become the root cause of many Internet attacks. To be well prepared for future attacks, it is not enough to study how to detect and defend against the botnets that have appeared in the past. More importantly,(More)
In this demo, we present the Microsoft Complex Event Processing (CEP) Server, Microsoft CEP for short. Microsoft CEP is an event stream processing system featured by its declarative query language and its multiple consistency levels of stream query processing. Query composability, query fusing, and operator sharing are key features in the Microsoft CEP(More)
Blood–brain barrier (BBB) leakage plays a key role in cerebral ischemia–reperfusion injury. It is quite necessary to further explore the characteristic and mechanism of BBB leakage during stroke. We induced a focal cerebral ischemia model by transient middle cerebral artery occlusion in male rats for defining the time course of BBB permeability within 120 h(More)
Appropriate application of service selection based on QoS-aware can bring great benefits to service consumers, as it is able to reduce redundancy in search. It also generates advantages for service providers who deliver valuable services. However, non-functional QoS attributes are not easy to measure due to their complexity and the involvement of consumer’s(More)
| The mobile social network (MSN) combines techniques in social science and wireless communications for mobile networking. The MSN can be considered as a system which provides a variety of data delivery services involving the social relationship among mobile users. This paper presents a comprehensive survey on the MSN specifically from the perspectives of(More)
Many components of variability become larger percentage design factors with decreasing feature size. Hence, the small transistors in SRAM cells are particularly sensitive to these variations. The SRAM cell transistors in sub-100-nm designs may contain fewer than 100 channel dopant atoms. To achieve a robust design with such variability, one must enhance the(More)
Arrays of micrometer-scale needles could be used to deliver drugs, proteins, and particles across skin in a minimally invasive manner. We therefore developed microfabrication techniques for silicon, metal, and biodegradable polymer microneedle arrays having solid and hollow bores with tapered and beveled tips and feature sizes from 1 to 1,000 microm.
