This paper describes the design, implementation, and machine learning issues associated with developing a control system for a serpentine robotic manipulator. The purpose of the control system is to provide autonomous/teleoperative control of the serpentine robotic manipulator, as well as full robotic control during operation of the manipulator within an enclosed environment such as an undergro...

Nuclear ribosomal DNA (ITS and ETS) sequences from 39 native Californian (USA) Allium species and congeners were combined with 154 ITS sequences available on GenBank to develop a global Allium phylogeny with the simultaneous goals of investigating the evolutionary history (monophyly) of Allium in the Californian center of diversity and exploring patterns of adaptation to serpentine soils. Phylo...

While the signal quality of recording neural electrodes is observed to degrade over time, the degradation mechanisms are complex and less easily observable. Recording microelectrodes failures are attributed to different biological factors such as tissue encapsulation, immune response, and disruption of blood-brain barrier (BBB) and non-biological factors such as strain due to micromotion, insul...

An intracellular conformational switch in the serpentine transmembrane protein Smoothened appears to underlie Hedgehog pathway activation. The switch is gated by electrostatic interactions that are regulated by multiple phosphorylations, potentially endowing a dose-dependent response.

The serpentinite rock is formed by minerals of the serpentine group, such as antigorite and lizardite, can be found in several countries around world. It has commercial applications, among them its use an ornamental rock. numerous constructions, churches, houses buildings. However, trade names are adopted for rocks, making it difficult to identify confirm existence specific Using bibliographica...

The mam plant communities of ultramafic (serpentine) outcrops of a Mediterranean area in central Italy are described and their successional pathway discussed. Four vegetation stages are distinguished: a) an endemic garigue stage, with high percentage of exposed rocky soil belonging to Armerio-Alyssetum bertolonii; b) a garigue stage similar to the previous one but with several Mediterranean eve...

For a PEMFC to work better, adding baffles flow channel can improve reactant transfer. As result, the starts by developing 3-D numerical model for vanadium redox battery (VRFB) using COMSOL Multiphysic Simulation Software. By incorporating into serpentine channel, it is possible simulate changes in ion concentration and terminal voltage. The findings indicate that efficiency will be impacted ba...
