In the diego de Almagro archipelago of southern chile, a quartz rich mica schist and a mylonitized granite contain Late Jurassic zircons of ca 166 and 170 Ma respectively. these rocks were metamorphosed during the cretaceous in a subduction zone environment, which developed blueschist assemblages in metabasalts interleaved with the mica schist. the dated rocks were probably part of the acid large igneous province developed in southwestern Gondwanaland during the extensional phase which preceded the dismembering of the supercontinent. they constitute evidence that tectonic erosion of the margin occurred, as these siliceous igneous rocks, formed in the South American upper plate, were transported in the subduction zone to some 20 km depth prior to their exhumation. these rocks are in tectonic contact through the Seno Arcabuz shear zone, with late Permian turbidites of the duque de York complex, which did not undergo blueschist metamorphism.

this work describes an improved feature extractor algorithm to extract the peripheral features of point x(ti,fj) using a nonlinear algorithm to compute the nonlinear time spectrum (NL-tS) pattern. the algo- rithm observes n×n neighborhoods of the point in all directions, and then incorporates the peripheral fea- tures using the Mel frequency cepstrum components (MFccs)-based feature extractor of the tsinghua elec- tronic engineering speech processing (tHEESP) for Mandarin automatic speech recognition (MASR) sys- tem as replacements of the dynamic features with different feature combinations. In this algorithm, the or- thogonal bases are extracted directly from the speech data using discrite cosime transformation (dct) with 3×3 blocks on an NL-tS pattern as the peripheral features. the new primal bases are then selected and simplified in the form of the ?dp- operator in the time direction and the ?dp- operator in the frequency di- t f rection. the algorithm has 23.29% improvements of the relative error rate in comparison with the standard MFcc feature-set and the dynamic features in tests using tHEESP with the duration distribution-based hid- den Markov model (ddBHMM) based on MASR system.

toxic insects advertise their defended state to potential predators using warning displays. Frequently these displays use cues through more than one sensory modality, and combine color, smell and sound to produce a multimodal warning display. Signalling through more than one sensory pathway may enhance the rate of avoidance learning, and the memorability of the learned avoidance. A common insect warning odor, pyrazine, has previously been shown to increase the rate of learned avoidance of unpalatable yellow prey by domestic chicks （GaUus gallus domesticus）, and the odor also improved memory of this learned avoidance. However, to date no research has examined this response to pyrazine odor using wild birds under natural conditions. this study used wild robins （Erithacus rubecula） to investigate whether wild birds avoided yellow baits that smelled of pyrazine more strongly than those presented with no odor. the results provide some evidence that pyrazine odor does increase the level of protection an aposematic insect gains from a wild avian predator, but that the effect of pyrazine on learned avoidance was much weaker than was found with domestic chicks .

the transformation productions of hot-deformation simulation experiments were investigated using a Gleeble-1500 hot simulator for a commercial pipeline steel. Based on the investigation results, the improved thermo-mechanical control processing (tMcP) schedules containing a two stage multi-pass controlled rolling coupled with moderate cooling rates were applied to hot rolling experiments and acicular ferrite dominated microstructure was obtained. Microstructures and mechanical properties of hot rolled plates were related to tMcP processing, and regression equations describing the relation between processing parameters and mechanical properties in the current tMcP were developed, which could be used to predict mechanical properties of the experimental steel during commercially processing. It was found that with an increase in cooling rate after hot rolling, grain size in the microstructure became smaller, the amount of polygonal ferrite decreased and acicular ferrite increased, and accordingly mechanical properties increased.

Background： A novel extruded product was characterized with a metabolism and lactation trial to establish the product＇s energy content, and its effects on lactating sow performance. the product was composed of a 60：40 corn-soybean blend, which was then extruded. this product containing the co-extruded 60：40 corn-soybean blend was commercially developed and is used extensively in swine diets in southwest Minnesota. GE of dietary treatments were determined by isoperibol bomb calorimetry. twelve barrows （59.9 ± 1.4 kg）, were used to determine the digestible and metabolizable energy of the extruded product. dE of treatments was determined by subtracting fecal energy from GE provided to barrows by each respective treatment. ME was determined by subtracting urinary energy from calculated digestible energy. Sixty-three sows were used for the lactation trial. three dietary treatments were utilized： cONtROL （an industry standard diet）; PROdUct （contained the product, vitamins and minerals）; OIL （matched the lysine：ME ratio of PROdUct by addition of soy oil）. Sow weight, backfat thickness at the right and left last ribs, body condition score, number of piglets, and litter weights were recorded on the date of farrowing （d 0）, （d 9）, and at weaning. Blood and milk samples were obtained at weaning, and blood was analyzed for plasma urea nitrogen （PUN）, milk was analyzed for total protein and fat content. Results： On a dry-matter basis, the test diet provided 3,908 kcal/kg dE and 3,833 kcal/kg ME, which was significantly greater than the basal diet, which provided 3,633 kcal/kg dE and 3,567 kcal/kg ME （P 〈 0.0001）. these data were used to establish the dE and ME of the product, which were 3,882 kcal/kg and 3,798 kcal/kg, respectively, on an as-fed basis. No effect of diet was observed for changes in sow backfat （RBF P = 0.24; LBF P = 0.07） or body condition score （P = 0.12） during lactation. Milk total protein （P = 0.69）, fat （P = 0.66）, PUN, average piglet gain （P = 0.55） and pi
