Plate convergence can induce large-scale metamorphism and magmatism, reshape large parts of continental margins, subsequently change regional climate biodiversity. Metamorphic rocks in orogenic belts commonly record different metamorphic evolutions temporal-spatial distributions at the scale, which are strongly influenced by convergent processes through time. In some cases, ultrahigh-pressure (...

Malware is one of the significant problems in the current Internet. Often security tool vendors develop an attack signature to deal with the attacks. However attack techniques such as polymorphism and metamorphism can be used by the attacker to generate multiple variants of the malware and complicate the signature identification. In this paper we present our analysis on sample set of malware an...

Laser-Raman imagery is a sensitive, noninvasive, and nondestructive technique that can be used to correlate directly chemical composition with optically discernable morphology in ancient carbonaceous fossils. By affording means to investigate the molecular makeup of specimens ranging from megascopic to microscopic, it holds promise for providing insight into aspects of organic metamorphism and ...

Nowadays viruses use polymorphic techniques to mutate their code on each replication, thus evading detection by antiviruses. However detection by emulation can defeat simple polymorphism: thus metamorphic techniques are used which thoroughly change the viral code, even after decryption. We briefly detail this evolution of virus protection techniques against detection and then study the METAPHOR...
