Circular graphite discs, among abundant irregular graphite particles, have been extracted from ArcheanPaleoproterozoic amphibolite grade metamorphic rocks in the Wutaishan area of North China. Raman spectroscopic analysis indicates that these graphite discs experienced maximum metamorphic temperature of 513 ± 50 °C. The discs bear morphological features related to metamorphism, but they are als...

This paper reviews some current applications of porphyroblast microstructures, some difficulties with interpreting them, and some possible directions for future studies. Porphyroblast microstructures have attracted the attention and imagination of geologists for more than a century, and have enjoyed a resurgence in popularity over the last two decades. Although commonly complex, they are of bro...

CONRO: Towards Miniature Self-Su cient Metamorphic Robots Andr es Casta~ no Wei-Min Shen Peter Will Information Sciences Institute University of Southern California 4676 Admiralty Way Marina del Rey, CA 90292 Abstract Metamorphic robots are an emerging eld in which robots can dynamically and intelligently recon gure shape and size not only for individual robots (intrarobot metamorphing) but als...

The metamorphic sole rocks at the base of mantle peridotites from the Mersin ophiolite consist of amphibolites and metasedimentary lithologies. Mineral parageneses in the metamorphic sole rocks exhibit amphibolite and greenschist facies assemblages. Geothermobarometric studies based on mineral assemblages and chemical compositions of minerals indicate that average metamorphic temperature during...

The structure and distribution of organic sulfur in coals of different rank and different sulfur content were studied by combining mild organic solvent extraction with XPS technology. The XPS results have shown that the distribution of organic sulfur in coal is related to the degree of metamorphism of coal. Namely, thiophenic sulfur content is reduced with decreasing metamorphic degree; sulfoni...

CHI-SQUARED DISTANCE AND METAMORPHIC VIRUS DETECTION by Annie H. Toderici Malware are programs that are designed with a malicious intent. Metamorphic malware change their internal structure each generation while still maintaining their original behavior. As metamorphic malware become more sophisticated, it is important to develop efficient and accurate detection techniques. Current commercial a...

Challenges arise in testing applications that do not have test oracles, i.e., for which it is impossible or impractical to know what the correct output should be for general input. Metamorphic testing, introduced by Chen et al., has been shown to be a simple yet effective technique in testing these types of applications: test inputs are transformed in such a way that it is possible to predict t...

Metamorphic robots are an emerging eld in which robots can dynamically recon gure shape and size not only for individual robots (intra-robot metamorphing) but also for complex structures that are formed by multiple robots (inter-robot metamorphing). Such capability is highly desirable in tasks such as re ghting, earthquake rescue, and battle eld scouting, where robots must go through unexpected...

Structural field relations, petrologic and geochemical studies, and radiometric age aualysis of metamorphic rocks at the base of the Brooks Range ophiolite provide a record of the time, tectonic setting, and initial conditions of ophiolite emplacement during the Middle Jurassic western Brookian orogeny. The metamorphic sole of the Misheguk, Siniktanneyak, and Avan Hills ophiolite bodies is tran...

To study the ontogeny of the vasotocin (VT) system and its contribution to anuran metamorphosis, VT mRNA levels were determined by Northern blot analysis in metamorphosing bullfrog tadpoles. Effects of osmotic stimulation on VT mRNA levels were also analyzed in order to follow the development of osmotic responsiveness of VT neurons. The intensity of hybridization signals for VT mRNA gradually i...
