Multi-wavelength, multi-beam, photonic based sensor for object discrimination and positioning
… of advanced laser scanning systems for discrimination in perimeter security, defence, agriculture, transportation, surveying and geosciences. Military forces, in particular, have already started employing laser scanning technologies for projectile guidance, surveillance, satellite and …

Memory for objects and places following lesions of the hippocampus or perirhinal cortex in rats
Retrograde memory for object discrimination problems and spatial information was assessed in rats that had received either bilateral aspiration lesions of the perirhinal cortex or bilateral NMDA lesions of the hippocampus. Rats learned three different object discrimination problems: They learned …

Data Reduction for Diverse Optical Observers through Fundamental Dynamic and Geometric Analysis
… into the behavior of both stars and space objects viewed through optical sensors. This type of analysis has the potential to enable data collection from a wider variety of sensors, increasing both the quantity and quality of data available for space object catalog maintenance. This …

Relative habituation and recovery of visual attention to orientation-movement compounds by newborn infants.
… infants are capable of discriminating stationary objects based on one stimulus dimension. The present study asked the following questions: can newborns process spatial orientation changes?; does stimulus movement influence spatial orientation processing?; can stimulus movement changes be …

Robustness of Novelty Preference For A Motion-Based One-Trial Object Recognition Task In Male and Female Adolescent Rats
<p>One-trial object recognition (OR) is a popular paradigm for conducting stress-free studies of rodent recognition memory. Rodents' response to novelty depends upon complex interactions between intrinsic and extrinsic motivations, many of which decrease validity for measures operationally defining …

How does the primate ventral visual stream causally support core object recognition?
… difficult visual task of invariant object recognition - the ability to discriminate between different objects in the face of high variation in object viewing parameters and background conditions. This ability is thought to rely on the ventral visual stream, a hierarchy of visual …

Leveraging Temporal Dynamics to Enhance Radar-Based Object Detection in Adverse Weather for Autonomous Vehicles
… robust perception systems to detect and localize objects reliably under all environmental conditions. While cameras and LiDAR provide high-resolution perception, they suffer significant performance degradation in adverse weather. Radar sensors, with their inherent resilience to lighting variations …

Characterising trait anxiety in the common marmoset (Callithrix jacchus): investigations into behavioural, psychophysiological and cognitive phenotypes
… group). The remaining 74% showed successful discrimination (‘passed’ group). Additional regression analysis on several behavioural and physiological responses early in training revealed two potential biomarkers of high trait anxiety in marmosets: suppressed baseline blood pressure, indicative …

Design and development of a sensory feedback system for transradial amputees using body powered prostheses
… in the form of improved results in an object identification and size discrimination (OISD) test, improved percieved confidence and improved response time. Materials & Methods A sensory feedback system was developed using principles of rapid prototyping and testing. The system utilises …

Development and application of an echolocation model inspired by bats
… the effect of auditory processing<br/>on the object discrimination is investigated for both CF (constant frequency) and FM<br/>(frequency modulated) signals respectively. These signals are considered as two representative<br/>types of echolocating calls. This study has simulated returning …

Effects of acute and repeated cannabinoid injections on immediate and delayed object memory and unconditioned anxiety – a developmental trajectory
… adolescence, but not adulthood, results in object memory impairments following a period of no-drug administration. In tests of unconditioned anxiety, acute THC evokes anxiety-like activity at higher doses. Conversely, CBD blocks object memory impairment in models that produce inflammation …

Manipulating spatial frequency to understand global and local information processing in 7-month-old infants
… easiest way to do this is to filter real life objects of their high and low spatial frequencies. High spatial frequencies provide information about the smaller parts where as low spatial frequencies provide information about the larger ones. By removing high or low spatial frequency we can …
