We present a method for tracking and distinguishing multiple C. elegans in a video sequence, including when they are in physical contact with one another. The worms are modeled with an articulated model composed of rectangular blocks, arranged in a deformable configuration represented by a spring-like connection between adjacent parts. Dynamic programming is applied to reduce the computational ...

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...

With increasing speed, virulence, and sophistication, self-propagating worms continue to pose a serious threat to the safety of the Internet. To effectively identify and defend against self-propagating worms, a critical task is to characterize a worm along multiple dimensions. Content-based fingerprinting is a well-established dimension for worm characterization by deriving the most representat...

To detect and defend against Internet worms, researchers have long hoped to have a safe convenient environment to unleash and run real-world worms for close observation of their infection, damage, and propagation. However, major challenges exist in realizing such “worm playgrounds”, including the playgrounds’ fidelity, confinement, scalability, as well as convenience in worm experiments. In thi...

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 ...

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...

BACKGROUND Co-occurrence of malaria and filarial worm parasites has been reported, but little is known about the interaction between filarial worm and malaria parasites with the same Anopheles vector. Herein, we present data evaluating the interaction between Wuchereria bancrofti and Anopheles punctulatus in Papua New Guinea (PNG). Our field studies in PNG demonstrated that An. punctulatus util...

Canthariasis is a human/ animal infestation by larval stages of coleopteran insects - the beetles. This study reports rare case gastrointestinal canthariasis caused Alphitobiusdiaperinus. A six-year-old boy presented with complaints pain abdomen associated non-bilious, non-blood-stained vomiting for 15 days and history passage worm-like creatures via stools occasionally in vomitus. All investig...

Given a coloring of the vertices, we say subgraph H is monochromatic if every vertex of H is assigned the same color, and rainbow if no pair of vertices of H are assigned the same color. Given a graph G and a graph F , we define an F -WORM coloring of G as a coloring of the vertices of G without a rainbow or monochromatic subgraph H isomorphic to F . We present some results on this concept espe...
