Characterizing operant hyperactivity in the Spontaneously Hypertensive Rat

open access: yesBehavioral and Brain Functions, 2012
Background Operant hyperactivity, the emission of reinforced responses at an inordinately high rate, has been reported in children with ADHD and in the Spontaneously Hypertensive Rat (SHR), the most widely studied animal model of ADHD.

Advanced Manufacturing of Composite‐Based Systems for Energy Applications

open access: yesAdvanced Materials Technologies, EarlyView.
Advanced manufacturing enables the integration of polymers, ceramics, metal oxides, and composites into architected microstructures with tailored transport pathways. By coupling material selection, manufacturing strategy, and structural design, multifunctional energy systems can simultaneously improve electrochemical performance, thermal management ...

The Effects of Altering Maintenance Diet on Food Preferences of Hens [PDF]

open access: yes, 2013
The preferences of six hens for wheat, puffed wheat and pellets were investigated using Variable Interval 60-s Variable Interval 60-s dependent concurrent schedules of reinforcement with a 2-s change-over delay and 2.5-s access to wheat on the left key ...

Multiobjective Codesign Optimization of a Planar Pneumatic Artificial Muscle‐Based Snake‐Like Robot for Enhanced Agility and Energy Efficiency

open access: yesAdvanced Robotics Research, EarlyView.
A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...

The effects of signalled reinforcement in multiple schedules of reinforcement [PDF]

open access: yes, 1970
In a two-component multiple variable interval schedule of reinforcement, responding in a blue, nonsignalled component was found to be a decreasing, negatively accelerated function of the rate of reinforcement in a red, signalled component. It was clearly

ChicGrasp: Imitation‐Learning‐Based Customized Dual‐Jaw Gripper Control for Manipulation of Delicate, Irregular Bio‐Products

open access: yesAdvanced Robotics Research, EarlyView.
Automated poultry processing lines still rely on humans to lift slippery, easily bruised carcasses onto a shackle conveyor. Deformability, anatomical variance, and hygiene rules make conventional suction and scripted motions unreliable. We present ChicGrasp, an end‐to‐end hardware‐software co‐designed imitation learning framework, to offer a ...

Dog Behaviour - Effect of Delay To Reinforcement [PDF]

open access: yes, 2012
Dogs were fed dry food as reinforcement and were required to touch a wand with their nose to get that reinforcement. In the first study, half the dogs were given immediate reinforcement, while for the remaining dogs reinforcement was delayed by two ...

A reinforcement learning model with choice traces for a progressive ratio schedule

open access: yesFrontiers in Behavioral Neuroscience
The progressive ratio (PR) lever-press task serves as a benchmark for assessing goal-oriented motivation. However, a well-recognized limitation of the PR task is that only a single data point, known as the breakpoint, is obtained from an entire session ...
