THE ACQUISITION OF OBSERVING [PDF]
Pigeons were exposed to stimuli correlated with the presence or absence of a variable‐interval 60‐second schedule of reinforcement only while they depressed a crossbar or “perch.” In the first experiment, the stimuli were different tilts of a line displayed on the key. When the difference in brightness between the line and the background (salience) was

A Rapid and Sensitive Salmonella Biosensor Based on Viscoelastic Inertial Microfluidics
Salmonella is a main cause of foodborne illnesses and rapid screening of Salmonella is the key to prevent Salmonella outbreaks, however available detection methods either require a long time, or need complex pretreatment, or have low sensitivity. In this

Monitoring the Etching Process of Hi-Bi Fiber Through a Fiber Loop Mirror
A method for monitoring the etching process of Hi-Bi fiber is proposed and demonstrated. The birefringence of the etching fiber is accurately calculated by tracking the shift of the interference spectrum in a high-birefringence fiber loop mirror ...

Optical bistability via an external control field in all-fiber ring cavity
We demonstrate a new scheme for realizing the Optical Bistability (OB) inside an all-fiber ring cavity with an external control field. In the absence of the external control field, the pump power is fixed below the threshold value of laser, and there is ...
