According to general relativity, astrophysical black holes are described by a small number of parameters.Apart from the mass of the black hole ( M ), among the most interesting characteristics is the spin ( a ), which determines the degree of rotation, i.e., the angular momentum of the black hole.The latter is observationally constrained by the spe
Snake robot locomotion in a cluttered environment where the snake robot utilises a sensory-perceptual system to perceive the surrounding operational environment for means of propulsion is defined as perception-driven obstacle-aided locomotion (POAL).From a control point of view, achieving POAL with traditional rigidly-actuated robots is challenging
REPAIR RESCUE The endocannabinoid system has been involved in the regulation of anxiety, and proposed as an inhibitory modulator of neuronal, behavioral and adrenocortical responses to stressful stimuli.Brain regions such as the amygdala, hippocampus and cortex, which are directly involved in the regulation of emotional behavior, contain high densi
