Abstract: Transcranial magnetic stimulation (TMS) is a non-invasive brain stimulation technique that has been approved by the Food and Drug Administration (FDA) as a treatment of depression. We tested the hypothesis that low frequency TMS exerts inhibitory effect on hyper excitable cortical state in patients with chronic insomnia and therefore could have therapeutic effect. We studied this in a pilot trial using low frequency TMS for patients with primary insomnia, We compared the change in insomnia scores between baseline and end of treatment in an open label trial with bifrontal low frequency TMS stimulation in seven patients with primary insomnia using daily stimulation of 3 weeks (15-week days). Patients between the ages of 21-65 years who meet DSM-IV criteria for Primary Insomnia were enrolled in the study. Results were positive. This study is the first of its kind to show positive effects of TMS in chronic insomnia.

Abstract: A method and a computer-implemented system are provided for calculating an affect score for a text corpus, so as to facilitate analysis of the sentiment inherent to that text corpus. A list of a plurality of words is provided, wherein each word is expressing affect. Words in the text corpus are matched with words contained in the list, and a frequency of the matched words is computed. Affect words are associated along at least one semantic dimension, and those derived from the semantic dimensions and the respective frequencies are aggregated using a Choquet integral function into an affect score.

Abstract: A system for providing information, management, and entertainment services is described. The system enables the user to select a service via a remote control. Once the system receives a request from the user, it processes the request to determine which service is requested and provides the service to the user.
