متن کاملA. a Probabilistic Approach to Certain Neuroelectric Phenomena
An acoustic stimulus presented at the ear of an anesthetized cat evokes an electrical response from the auditory nerve of that animal. Our primary stimuli to date have been clicks produced by feeding rectangular pulses of duration 0. 1 msec into a PDR-10 earphone. These short stimuli evoke spike-like responses, which are detected by a fine wire electrode placed within the bullar cavity. Suitabl...
متن کاملNanoscale Studies on Aggregation Phenomena in Nanofluids
Understanding the microscopic dispersion and aggregation of nanoparticles at nanoscale media has become an important challenge during the last decades. Nanoscale modeling techniques are the important tools to tackle many of the complex problems faced by engineers and scientists. Making progress in the investigations at nanoscale whether experimentally or computationally has helped understand th...
