Detecting mud hazards is a significant challenge to UGV autonomous off-road navigation. A military UGV stuck in a mud body during a mission may need to be sacrificed or rescued, both unattractive options. JPL is currently developing a daytime mud detection capability under the RCTA program using UGV mounted sensors. To perform robust mud detection under all conditions, we expect multiple sensor...

Drosophila neuroblasts divide asymmetrically by aligning their mitotic spindle with cortical cell polarity to generate distinct sibling cell types. Neuroblasts asymmetrically localize G i, Pins, and Mud proteins; Pins/G i direct cortical polarity, whereas Mud is required for spindle orientation. It is currently unknown how G i–Pins–Mud binding is regulated to link cortical polarity with spindle...

During the drilling and development of sour natural gas (including CO 2 H S) fields, due to high solubility in fluid, concealment after invasion increases, resulting well control accidents. Therefore, it is great significance for field deeply study understand acid flow law annular air liquid invasion. In this paper, a multiphase equation considering dissolution established. Based on existing ex...

one of the main concerns of the mining industry is to determine ultimate pit limits. final pit is a collection of blocks, which can be removed with maximum profit while following restrictions on the slope of the mine’s walls. the size, location and final shape of an open-pit are very important in designing the location of waste dumps, stockpiles, processing plants, access roads and other surfac...

Methane ebullition from lakes is an important contributor to atmospheric greenhouse gases. However, typically sampled at intervals greater than the duration of events, limiting our understanding factors controlling this flux. Here, we present high-frequency data a single site in boreal pit lake during open-water season between June 24 and 21 October 2018. We record every 30 min for first 2 mont...

OBJECTIVE Elevated serum phosphate has emerged as a major risk factor for vascular calcification. The sodium-dependent phosphate cotransporter, PiT-1, was previously shown to be required for phosphate-induced osteogenic differentiation and calcification of cultured human vascular smooth muscle cells (VSMCs), but its importance in vascular calcification in vivo and the potential role of its homo...
