a r t i c l e i n f o a b s t r a c t Abstract interpretation Program semantics Metamorphic malware detection Self-modifying programs Metamorphic code includes self-modifying semantics-preserving transformations to exploit code diversification. The impact of metamorphism is growing in security and code protection technologies, both for preventing malicious host attacks, e.g., in software divers...

More than 200 specimens from different occurrences of the Rogaland igneous complex and surrounding granulite facies metamorphic rocks (S. W. Norway) have been analysed by a direct non-destructive proton induced gamma-ray emission (PIGE) technique. The fluorine contents vary from < 25 ppm to 3500 ppm. There is a good correlation between the concentration of fluorine and that of phosphorus for ig...

Metamorphic robots with shape-changing capabilities provide a powerful and flexible approach to complex tasks in unstructured environments. However, due to their dynamic topology and decentralized configuration, metamorphic robots demand control mechanisms that go beyond those used by conventional robots. This paper builds on our previous results of hormone-based control, and develops a novel d...

in order to assess the presence or absence of fluids under peak metamorphic conditions within the inner aureole of the etive igneous complex in west scotland, eight suitable metabasic hornfels samples and one suitable pelitic hornfels were used to calculate water activities using a mineral equilibria. calculated activities for water are lower than unity in the pelitic sample and extremely low i...

A thick succession of sedimentary rocks belonging to Tipam Group is well exposed all along the road cut sections near Buhchang village, Kolasib district, Mizoram. The heavy mineral suite of the Tipam sediments depicts a cosmopolitan nature. It comprises dominantly of non-opaque variety that includes zircon, tourmaline, rutile, staurolite, kyanite, sillimanite, apatite, epidote, garnet and hornb...

INTRODUCTION The field trip today will concentrate mostly on the metamorphic effects on the Biwabik Iron Formation, at the Peter Mitchell mine of eastern Mesabi Iron Range, caused by intrusion of the nearby Mesoproterozoic Duluth Complex (1.1 Ga). The stratigraphy of the iron-formation that is used at this mine, and nearby mines, was mainly developed by Gundersen and Schwartz (1962) and is depi...

The earliest growth of post-metamorphic (postlarval) shells in two species of Eohadrotreta is described from the Cambrian Shuijingtuo Formation of South China. Two different growth patterns can be observed by quantifying developmental variations in size and shape of successive stages of post-metamorphic shell growth (including the pedicle foramen forming stage, pedicle foramen enclosing stage a...

the muteh gold deposit (ne of golpaygan) in the central part of intrusive-metamorphic belt of sanandaj-sirjan zone comprises nw-se trending gold-quartz vein occurred in metamorphic complex. gold mineralization is associated with quartz veins that formed during regional deformation across the mylonitic zones in metamorphic rocks of predominantly meta-volcanic, gneiss and schist. the sulfidation ...
