Detecting Agents [PDF]

open access: yesPhilosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2003
Abstract This paper reviews a recent set of behavioural studies that examine the scope and nature of the representational system underlying theory-of-mind development. Studies with typically developing infants, adults and children with autism all converge on the claim that there is a specialized input system that uses not only ...

Moving target detection in clutter background with FDA-MIMO radar via three-dimensional focus processing

open access: yesThe Journal of Engineering, 2019
Low observable moving target-detection technology under clutter background is the key factor affecting the radar performance. Here, frequency diverse array (FDA) MIMO radar is investigated for low-observable moving target detection.

MicroRNA-7, synergizes with RORα, negatively controls the pathology of brain tissue inflammation

open access: yesJournal of Neuroinflammation, 2020
Background Accumulating evidence has documented that microRNA-7 (miR-7) plays an important role in the pathology of various diseases. However, the potential role of miR-7 in brain tissue inflammation (BTI) remains unclear.

Multi-Dimensional Automatic Detection of Scanning Radar Images of Marine Targets Based on Radar PPInet

open access: yesRemote Sensing, 2021
Traditional radar target detection algorithms are mostly based on statistical theory. They have weak generalization capabilities for complex sea clutter environments and diverse target characteristics, and their detection performance would be ...

A detection theory account of change detection [PDF]

open access: yes, 2004
Previous studies have suggested that visual short-term memory (VSTM) has a storage limit of approximately four items. However, the type of high-threshold (HT) model used to derive this estimate is based on a number of assumptions that have been ...

Super resolution reconstruction for medical image based on adaptive multi-dictionary learning and structural self-similarity

open access: yesComputer Assisted Surgery, 2019
To improve the quality of the super-resolution (SR) reconstructed medical images, an improved adaptive multi-dictionary learning method is proposed, which uses the combined information of medical image itself and the natural images database.

An Evasion and Counter-Evasion Study in Malicious Websites Detection [PDF]

open access: yes, 2014
Malicious websites are a major cyber attack vector, and effective detection of them is an important cyber defense task. The main defense paradigm in this regard is that the defender uses some kind of machine learning algorithms to train a detection model,

Fluorometric assay for quantitation of biotin covalently attached to proteins and nucleic acids

open access: yesBioTechniques, 2007
As a component of the (strept)avidin affinity system, biotin is often covalently linked to proteins or nucleic acids. We describe here a microplate-based high-throughput fluorometric assay for biotin linked to either proteins or nucleic acids based on ...
