Activation of Neurotransplants in Humans

Experimental Neurology, 1999
Clinical studies report symptomatic benefit in most fetal neurotransplantation treated Parkinson's disease patients. The underlying mechanism is incompletely explained. We investigated whether neural connections between host and transplanted tissue are established. Two Parkinson's disease patients with clinically excellent outcome after transplantation

Recognizing human activities

Proceedings of the IEEE Conference on Advanced Video and Signal Based Surveillance, 2003., 2004
The paper deals with the problem of classification of human activities from video as one way of performing activity monitoring. Our approach uses motion features that are computed very efficiently and subsequently projected into a lower dimension space where matching is performed.

FIBRINOLYTIC ACTIVATOR ACTIVITY IN HUMAN NEOPLASMS

Plastic and Reconstructive Surgery, 1978
The results of this study suggest that many malignant tumors contain low levels of fibrinolytic activator activity. Evidence is presented to suggest that this low activity may be due to the presence of an inhibitor of fibrinolysis. The presence or absence of measurable fibrinolytic activator activity, and/or inhibitor in neoplastic growths may enable ...

Human activity analysis

ACM Computing Surveys, 2011
Human activity recognition is an important area of computer vision research. Its applications include surveillance systems, patient monitoring systems, and a variety of systems that involve interactions between persons and electronic devices such as human-computer interfaces.

Effectors of the activation of human [Glu1]plasminogen by human tissue plasminogen activator

Biochemistry, 1988
The activation of human [Glu1]plasminogen [( Glu1]Pg) by human recombinant (rec) two-chain tissue plasminogen activator (t-PA) is inhibited by Cl-, at physiological concentrations, and stimulated by epsilon-aminocaproic acid (EACA), as well as fibrin(ogen).

Active Sensing in Human Activity Recognition

2017
This work studies the problem of reducing the energy consumption of wearable sensors in a Human Activity Recognition (HAR) system. A HAR system is implemented using Hidden Markov Models, where decisions over the acquisition of new data are made based on the entropy of the posterior distribution of the activities. This problem is intractable in general,
