Repeated administration of cocaine often results in tolerance to its effects on operant behavior. The tolerance is often associated with an initial drug effect that results in loss of reinforcement. Cocaine can also produce effects that result in a g

We have observed intrinsic Josephson effects for current flow perpendicular to the CuO2 planes in HTSC thin films. Tl‐Ba‐Ca‐Cu‐O thin films were deposited on step edges in LaAlO3 substrates. Due to the special preparation process, microbridge

TIBaCaCuO (TBCCO) belongs to a class of HTSC materials showing very high critical temperatures up to 127 K and a strong anisotropy of the superconducting properties. This is caused by a layered lattice structure responsible especially for the observe

We have investigated the modification of high- T c superconducting film structures due to ion beam irradiation using a mask technology. The YBa 2 Cu 3 O 7 (YBCO) and GdBa 2 Cu 3 O 7 (GBCO) thin film microbridges were covered with electron resits (PMM

We report on microwave emission experiments of Bi/sub 2/Sr/sub 2/CaCu/sub 2/O/sub 8+y/-single crystals at frequencies between 12 GHz and 95 GHz. Due to the intrinsic Josephson effect these samples form series connections of typically 2000 contacts. F

The geometry of sub-half-micron features of thin films of cross linked novolak, which are formed by a three-layer-resist process, is found to be dependant not only on the conditions of preparation, but on the feature size, too. Small features show a

Four pigeons responded under a fixed-interval 8-min schedule of food delivery in which the amount of food delivered at the end of each interval depended on performance during the interval (i.e., a correlated schedule). Specifically, duration of acces
