This paper describes the system used in Task-7 (Analysis of Clinical Text) of SemEval-2014 for detecting disorder mentions and associating them with their related CUI of UMLS1. For Task-A, a CRF based sequencing algorithm was used to find different medical entities and a binary SVM classifier was used to find relationship between entities. For Task-B, a dictionary look-up algorithm on a customi...

Many learning situations involve multiple sets of training examples drawn from different but related underlying models. "Family dis-­ covery" is the task of discovering a parameterized family of models from this kind of training set. The task naturally arises in density estimation, classification, regression, manifold learning, reinforce­ ment learning, clustering, HMM learning, and other setti...

Introduction: Human factor analysis has been identified as the most common cause of accidents in natural gas transportation and distribution facilities. The occurrence of accidents at these systems, especially gas reduction stations located in residential and industrial areas, has had catastrophic consequences. Therefore, this study aimed at analyzing critical tasks and human error assessment u...

BACKGROUND Falls related to balance dysfunction are among the major problems of older individuals. The timing characteristics of protective voluntary stepping are critically related to effective balance recovery and are often delayed and slowed with age. This study investigated the influence of step training on the timing characteristics of voluntary step initiation in younger and older adults....

BACKGROUND AND PURPOSE There is increasing interest in the potential benefits of circuit class training after stroke, but its effectiveness is uncertain. Our aim was to systematically review randomized, controlled trials of task-oriented circuit class training on gait and gait-related activities in patients with stroke. METHODS A computer-aided literature search was performed to identify rand...

Perceptual decision-making in which decisions are reached primarily from extracting and evaluating sensory information requires close interactions between the sensory system and decision-related networks in the brain. Uncertainty pervades every aspect of this process and can be considered related to either the stimulus signal or decision criterion. Here, we investigated the learning-induced red...

Traditionally, repetitive practice of a task is used to learn a new skill, exhibiting as immediately improved performance. Research suggests, however, that a more experience-based rather than exposure-based training protocol may allow for better transference of the skill to related tasks. In synergy-based motor control theory, fundamental motor skills, such as hand grasping, are represented wit...

We have reported previously that intensive preparation for a standardized test that taxes reasoning leads to changes in structural and functional connectivity within the frontoparietal network. Here, we investigated whether reasoning instruction transfers to improvement on unpracticed tests of reasoning, and whether these improvements are associated with changes in neural recruitment during rea...
