Abstract: A computer-implemented method of performing a semantic search in a source document database containing documents that are identified by a unique document identifier, including: reading a text component of a text-containing query; generating a set of query features from the text component of the query using a predefined feature extraction model; generating a set of training features based on the plurality of query features; training a trainable classifier with the training features and a set of document features obtained from at least a portion of the source documents using a predefined feature extraction model; selecting a number of source documents for classification according to a predefined selection scheme; obtaining features of the selected documents; classifying the selected source documents into different classes of relevance by using features of the selected documents, where at least one value of relevance is associated with each selected document; ranking the classified documents in an ordered list b

Abstract: A user interface system for performing searches in text-containing documents including a graphical user interface. The system may include a query window management system operable to display a query window for receiving a query text input by a user; a search result presentation system operable to display a search result window for displaying a result list of relevant documents returned by a search; a preview window management system operable to display a preview window for displaying at least part of the content of a relevant document listed in the search result window; and an activation tool operable to start a search at a search engine based on the query text, wherein the query window management system is adapted to receive a text of any length in the query window and to forward the text received in the query window to the search engine.

Abstract: A method and system for treating brain disorders comprises detecting activity of a first target area of the brain via a first implanted sensor and determining the presence of target brain activity by analyzing the detected brain activity in combination with treating the user based upon the determined presence of target brain activity by supplying a first therapeutic agent to the first target area via a first implanted fluid delivery member including at least one distal opening adjacent to the first target area. In addition, the system may be used as well for testing the effectiveness of drugs.

Abstract: A minivalve for delivering one of a control solution or a drug solution to a point of interest in a freely moving animal. The minivalve is portable by the freely moving animal, such as a mouse, rat, or primate, on its head without interfering with its behavior. The minivalve having an input for a control solution and an input for a drug solution and further having a common output for outputting either of the control solution or drug solution to an input of a microdialysis probe implanted at a point of interest in the animal. Also provided are systems for delivering one of a control solution or a drug solution to a point of interest in the animal. The system comprises the minivalve, a drug ejection device such as a microdialysis probe or injection cannula implanted at the point of interest in the small animal, and a microelectrode placed adjacent to the drug ejection device.

Abstract: A miniature apparatus for the treatment of brain disorders is provided which is a combination of electronic and pharmacological devices placed and powered entirely within the human body. The apparatus is based on the dual, electrical—molecular, nature of intercellular communication in the brain. The hybrid neuroprosthesis monitors the electrical activity of a dysfunctioning brain area, analyzes the incoming electrical signals, and delivers drug molecules into the dysfunctioning area to correct its function. The apparatus delivers drugs into the brain in such a way that the timing and duration of the drug deliveries are determined by the brain's own electrical activity.
