Sludge production is an avoidable problem arising from the treatment of wastewater. The sludge remained after municipal wastewater treatment contains considerable amounts of various contaminants and if is not properly handled and disposed, it may produce extensive health hazards. Application of aquatic worm is an approach to decrease the amount of biological waste sludge produced in wastewater ...

In recent years, worms have become one of the major threats to the security of the Internet. In this talk, I will present our research on modeling, analysis, and mitigation of Internet worm attacks, which includes: (1) We present a “two-factor worm model”, which considers the impact of human counteractions and network congestion on a worm's propagation. (2) To detect the presence of an Internet...

As email becomes one of the most convenient and indispensable communication mediums in our life, it is very important to protect email users from increasing email worm attacks. In this paper, we present the architecture and system design of a “feedback email worm defense system” to protect email users in enterprise networks. The defense system is flexible and able to integrate many existing det...

Patterns of nematode fecundity were investigated for infections of the caecal worm Heterakis gallinarum in the ring-necked pheasant (Phasianus colchicus). Worm length was a good predictor of parasite fecundity. After controlling for worm length no other factors, including parasite intensity, were related to worm fecundity. Density dependence in worm size was detected in natural infections at pa...

Mechanosensation plays a pivotal role in many aspects of pain pathology, yet the mammalian molecular transduction apparatus responsible for this sensory modality remains unknown. In January's edition of Nature Neuroscience, O'Hagan, Chalfie and Goodman [1] have provided direct electrophysiological evidence that somatic mechanotransduction in C. elegans is mediated by a complex of proteins previ...
