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...

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...

A new detection approach based on worm behaviors for IDS anti-worm is presented. By the method, the susceptible hosts probed by worms can be detected, and then an immediate counter-attack to the susceptible host can be proposed. As a case study, a simulation on the IDS-based anti-worm counter-attacking the malicious worm is given, which shows the new containment is much more effective and bring...

Some people have argued that software is artistic. If so, what about malware? Only occasional, small-scale attempts have been made to create art using malware. We present “art worms,” worms which allow an artist to use the entire Internet as a canvas. These worms could be interactive, allowing an artist to stage a global performance, or non-interactive and automatic. Examples are given of artwo...

a rare case of ascaris coming out through the anterior abdominal wall is reported here. a 40‑year‑old female had undergone dilatation and curettage by a quack. on the second day she presented with presented with features of peritonitis. she was explored. resection anastomosis of the ileum was done for multiple perforations of the ileum. patient developed a fistula in the anterior abdominal wall...

We give the first systematic investigation of the design space of worm defense system strategies. We accomplish this by providing a taxonomy of defense strategies by abstracting away implementationdependent and approach-specific details and concentrating on the fundamental properties of each defense category. Our taxonomy and analysis reveals the key parameters for each strategy that determine ...
