Abstract: Systems, methods, and products are described for enabling a user to enter data into a device without a keyboard. A virtual keyboard in accordance with the invention may include a sensor to detect actual or intended finger movements or other changes in the user's physiology, an element that generates a sequence of ambiguous pseudo-words based on the physiological changes, and a translator that translates the pseudo-words into words in a natural language and provides the natural language words to the device or to a data storage unit. The device typically may be a computer, electronic notepad, personal digital assistant, telephone, or other electronic device.

Abstract: Computer systems, methods, and products use adaptive systems, such as neural networks, to classify protein domains according to their hydropathic, steric, electrostatic, and other properties, and to predict the characteristics of domains with which they will bind based on these properties. Optionally, the systems, methods, and products also predict protein function based on the physical/chemical properties of one or more domains of the protein.
