Annals of Neurology, EarlyView.Objective Pathogenic variants in GNAO1 cause a spectrum of epilepsy, movement disorders, and developmental impairment. Clinical heterogeneity complicates prognosis and therapeutic development. We present the first longitudinal natural history study of GNAO1‐related disorders (GNAO1‐RD) to delineate phenotypic trajectories. Methods Sixty‐six individuals

SINR- and MI-Based Double-Robust Waveform Design
Entropy, 2022 Owing to cognitive radar breaking the open-loop receiving–transmitting mode of traditional radar, adaptive waveform design for cognitive radar has become a central issue in radar system research.

Interpreting algorithmic information cues: User sensemaking of search autocomplete moderation
Journal of the Association for Information Science and Technology, EarlyView.Abstract Autocomplete is a search feature that algorithmically generates information cues for any keywords entered in the search bar. While this feature makes the search process more efficient, it also frequently produces biased, misleading, offensive, or otherwise inappropriate suggestions.

Sensors, 2009 Dynamic spectrum access is a must-have ingredient for future sensors that are ideally cognitive. The goal of this paper is a tutorial treatment of wideband cognitive radio and radar—a convergence of (1) algorithms survey, (2) hardware platforms survey ...

, 2018 This paper describes some key ideas and applications of cognitive radars, highlighting the limits and the path forward. Cognitive radars are systems based on the perception-action cycle of cognition that sense the environment, learn from it relevant information about the target and the background, then adapt the radar sensor to optimally satisfy the ...

British Educational Research Journal, EarlyView.Abstract As front‐line observers and active participants in pupils' daily lives, teachers closely monitor pupils' social interactions, emotional states and behavioural changes. Their unique perspective enables them to detect problems in the social lives of their pupils that may not be immediately visible to peers, parents or mental health professionals.

Cognitive target detection based on Bayesian approach in radar
The Journal of Engineering, 2019 Cognitive radar (CR), which uses a closed-loop feedback perception-action cycle system, aims to develop a higher level of intelligence. In this study, the authors develop an efficient Bayesian approach to target detection in CR.

Cognitive Dynamic Systems: A Technical Review of Cognitive Radar
CoRR, 2016 We start with the history of cognitive radar, where origins of the PAC, Fuster research on cognition and principals of cognition are provided. Fuster describes five cognitive functions: perception, memory, attention, language, and intelligence. We describe the Perception-Action Cyclec as it applies to cognitive radar, and then discuss long-term memory,

A cognitive architecture for space time adaptive processing
, 2020 A cognitive radar can be conceived as a system that is able to autonomously and continuously change the parameters of both the transmitter and the receiver to optimise its performances in changing complex and changing environment with the available ...
