The peculiar Afrotropical bark beetle genus Xyloctonus Eichhoff, 1872 is revised and its biology described.Several unusual morphological features reflect adaptations to predator avoidance as they are highly exposed during mating externally on tree trunks and branches.Observations invariably indicate that males and females abandon the nest under bar
Predicting the springback angle has become the major production problem among tube benders.Springback is where the tube on a mandrel-less rotary draw bending tends to bounce back after being bent when the clamps are released.Accurately predicting the springback angle is crucial for effective tube bending.Machine learning (ML), click here a popular
chocolate chip cookie purse A phase-interrogation approach for the bulk refractive index sensing based on a silicon-on-insulator (SOI) ring resonator is introduced.The rapid phase variation around the resonance of the ring resonator is interrogated, and a single-sideband generation and coherent detection technology is adopted for the phase measurem
We report here the first dinosaur skeletal material described from the marine Fox Hills Formation (Maastrichtian) of western South Dakota.The find consists of two theropod pedal phalanges: one recovered from the middle part of the Fairpoint Member in Meade County, South Dakota; and the other from the Iron Lightning Member in Ziebach County, South D
Although dissimilarities in cranial and post-cranial morphology among African pygmies groups have been recognized, comparative studies on skull morphology usually pull all pygmies together assuming that morphological characters are similar 3m speedglas 9002nc among them and different with respect to other populations.The main aim of this study is t
