An analysis of errors in finite automata
(Elsevier, 1965-06)
This paper studies errors in finite automata. An error is defined as a pair of states and errors are then classified according to their probability of being corrected (i.e., being taken into the same state). Various results ...
Susceptibility to sensitization. I. Sex differences in the enduring effects of chronic -amphetamine treatment on locomotion, stereotyped behavior and brain monoamines
(Elsevier, 1988-09-01)
There are sex differences in a number of behaviors elicited by amphetamine (AMPH). The purpose of the present experiment was to determine if there are also sex differences in the sensitization of the locomotor activity and ...
Discovery of the Northeast Passage: the voyage of the VEGA, 1878–1879
(Kluwer Academic Publishers; Akademische Verlagsgesellschaft ; Springer Science+Business Media, 1979-07)
Branchial ventilation rates of cataleptic goldfish (Carassius auratus) and the effects of light and electric shock
(Elsevier, 1972-03)
Inverted, cataleptic goldfish showed an increase in ventilation rate over a 20 min period. The time-dependent increase in respiratory movement was initially suppressed when a 10 sec light or a 0.1 sec shock was presented ...
Protease nexin-1 activity in cultured Schwann cells
(Elsevier, 1991-07-08)
We report that protease nexin-1 (PN-1), a serine protease inhibitor known to have neurite-promoting effects, is made by Schwann cells in tissue culture. Three modalities have been used to demonstrate the presence of PN-1 ...
Ornithine decarboxylase activity in retinal explants of goldfish undergoing optic nerve regeneration
(Elsevier, 1981-06)
Retinal explants cultured in the presence of fetal calf serum (FCS) exhibit an increase in the activity of ornithine decarboxylase which is maximal several hours after explanation. The measured activity of this enzyme is ...
Solute concentration in the kidney-- I. a model of the renal medulla and its limit cases
(Elsevier, 1976)
We develop a general model of the renal medulla that is similar in geometry to the models reported by others. Two solutes are assumed to be present, one to play the role of salt and the other that of urea and similarly ...
Quantitative evaluation of the pH profile in organic acid fermentations
(Wiley Subscription Services, Inc., A Wiley Company, 1991-01-20)
No Abstrct.
Activity disc and cage for continuous measurement of running activity and core temperature in hamsters
(Elsevier, 1991-11)
We describe a design for the modular horizontal activity disc and tandem cages suitable for continuous monitoring of spontaneous running and of core tempertaures in golden hamsters. An acrylic disc is equipped with a short ...
Tail pinch induced stress-arousal facilitates brain stimulation reward
(Elsevier, 1979-01)
Adult male Sprague Dawley rats with chronic access to self stimulation were subjected to handling, tail pinch, or left undisturbed. Tail pinch increased responding for positive reinforcement while the other conditions did ...
