    Abstract: Disclosed is a method and system for efficiently and accurately tracking three-dimensional (3D) human motion from a two-dimensional (2D) video sequence, even when self-occlusion, motion blur and large limb movements occur. In an offline learning stage, 3D motion capture data is acquired and a prediction model is generated based on the learned motions. A mixture of factor analyzers acts as local dimensionality reducers. Clusters of factor analyzers formed within a globally coordinated low-dimensional space makes it possible to perform multiple hypothesis tracking based on the distribution modes. In the online tracking stage, 3D tracking is performed without requiring any special equipment, clothing, or markers. Instead, motion is tracked in the dimensionality reduced state based on a monocular video sequence.

    Abstract: Polypeptides comprising all or part of a variant integrin α subunit A domain or a variant integrin β subunit A-like domain are described. In solution or in membrane-associated form, the A domain or the A-like domain of the polypeptides of the invention exists predominantly in a high affinity conformation. In the polypeptides of the invention, referred to as variant integrin polypeptides, a crucial isoleucine residue (described in greater detail below) is absent. The isoleucine can be either deleted or replaced with different amino acids residue, preferably a smaller or less hydrophobic amino acid residue, e.g., alanine or glycine. Because the variant integrin polypeptides of the invention exist in solution or in membrane-associated form predominantly in a high affinity conformation, they are useful in screening assays for the identification of molecules that bind to (and/or mediate the activity of) an integrin. They are also useful for generating antibodies, e.g., monoclonal antibodies, which bind to the high affinity form of an integrin. Some such antibodies recognize an epitope that is either not present or not accessible on an integrin that is in a lower affinity conformation. The variant integrin polypeptides of the invention can be derived from any integrin α subunit or any integrin β subunit and could be used therapeutically. The variant integrin polypeptides preferably include a ligand-binding portion of an A-domain or an A-like domain.

    Abstract: A method of running a pulse tube refrigerator which has a regenerator and a pulse tube each defining a high temperature end and a low temperature end, the low temperature ends of the regenerator and the pulse tube being communicated with each other, and the high temperature end of the regenerator being connected to a gas compressor. A cold area is formed at the low temperature ends by periodically supplying working gas from the high temperature end of the regenerator to the regenerator and recovering the working gas from the regenerator. The temperature of the low temperature ends is raised by steadily, pulsatively or intermittently flowing gas in one direction through a communicating area between the low temperature ends of the regenerator and the pulse tube.

    Abstract: Word predictions in a message are selected or prioritized based on the recipient of the message and a previous location of use by a user. An input history is created based on messages sent to the recipient from the user at a particular location (e.g., global positioning system coordinates). As the user composes subsequent messages, a current location of the user is determined. Word predictions are performed based on a comparison of the current location to the previous locations, and based on the recipient(s). In further embodiments, location-aware spell-check functionality is provided for the messages.
