This study investigates motor skill performance and self-perceived competence in children with anxiety disorders compared with children without psychiatric disorders. Motor skills and self-perception were assessed in 329 children aged 8 to 11 years, from the Bergen Child Study. The Kiddie-SADS PL diagnostic interview was employed to define a group of children with an anxiety disorder without co...

PURPOSE To examine the relevance of physical disabilities for self-worth and perceived competence in children with cerebral palsy (CP), and to examine associations between behaviour problems and self-worth and perceived competence. METHODS The Harter scales for self-worth and perceived competence and a new scale for perceived motor competence were used in a sample of 80 children with CP. Thei...

Introduction: Since Curcuma longa extract and curcumin have been shown to be potent antioxidant agents, they were used in cultured adult mouse spinal cord slices to investigate whether they can inhibit apoptosis in motor neurons. Methods: Slices from the thoracic region of adult mice spinal cord were divided into four groups: 1. Freshlyprepared slices (time 0) 2. Control 3. Slices treated by cu...

induction motor bearing is one of the key parts of the machine and its analysis and interpretation are important for fault detection. in the present work vibration signal has been taken for the classification i.e. bearing is healthy (h) or defective (d). for this purpose, clustering based classification of bearing vibration data has been carried out using principal component analysis (pca) and ...

In this paper, a novel stator current based Model Reference Adaptive System (MRAS) estimator for speed estimation in the speed-sensorless vector controlled induction motor drives is presented. In the proposed MRAS estimator, measured stator current of the induction motor is considered as a reference model. The estimated stator current is produced in an adjustable model to compare with the measu...

BACKGROUND Low self-esteem is associated with depressive symptoms in children. However, the association between domains of self-esteem (e.g., self perceptions) and depressive symptoms may vary by gender. AIMS This study evaluated self-perceptions in relation to self-reported depressive symptoms in boys and girls. METHODS School children in grades 3 to 6 (n = 140; 54% boys; 46% girls) comple...

Performance variation is a critical issue in motor imagery brain-computer interface (MI-BCI), and various neurophysiological, psychological, and anatomical correlates have been reported in the literature. Although the main aim of such studies is to predict MI-BCI performance for the prescreening of poor performers, studies which focus on the user's sense of the motor imagery process and directl...

IN view of the number of papers that have appeared in recent years on* the neuromuscular systems of various groups of animals, it is somewhat surprising that no attempt has been made to clarify the position in regard to the insects. There can be no doubt that a particular interest attaches to this group from the standpoint of comparative physiology. As the most highly developed members of the A...

Based on existing data, we wish to put forward a biological model of motor system on the neuron scale. Then we indicate its implications in statistics and learning. Specifically, neuron’s firing frequency and synaptic strength are probability estimates in essence. And the lateral inhibition also has statistical implications. From the standpoint of learning, dendritic competition through retrogr...

The protein-remodeling machine Hsp104 dissolves amorphous aggregates as well as ordered amyloid assemblies such as yeast prions. Force generation originates from a tandem AAA+ (ATPases associated with various cellular activities) cassette, but the mechanism and allostery of this action remain to be established. Our cryoelectron microscopy maps of Hsp104 hexamers reveal substantial domain moveme...
