Abstract: The present invention provides a system and single or multi-functional element device that can be inserted and temporarily placed or implanted into a structure having a lumen or hollow space, such as a subject's abdominal cavity to provide therewith access to the site of interest in connection with minimally invasive surgical procedures. The insertable device may be configured such that the functional elements have various degrees of freedom of movement with respect to orienting the functional elements or elements to provide access to the site from multiple and different orientations/perspectives as the procedure dictates, e.g., to provide multiple selectable views of the site, and may provide a stereoscopic view of the site of interest.

Abstract: Systems and methods for suspended polymer photonic crystal (SPPC) cavities and waveguides are disclosed. In one aspect, photonic crystal cavities are provided. An exemplary photonic crystal cavity can include a substrate having a trench. A polymer film can be suspended above the trench thereby forming a gap between the polymer film and the substrate. The polymer film can include a plurality of holes to thereby form at least one optical cavity. The plurality of holes can have a lattice spacing, and each hole can have a radius. The radius and lattice spacing of the plurality of holes can be adapted to increase a gap-midgap ratio. In another aspect, photonic waveguides are provided. In another, methods for fabricating an SPPC are provided. In another, methods for sensing using a polymer photonic crystal ladder cavity are disclosed. In another, methods for optical filtering using an SPPC waveguide-coupled cavity drop filter are disclosed.

Abstract: Described is a transgenic mouse with two transgenes, each of which transgene comprises a DNA sequence encoding a dominant negative form of RbAp48 protein, wherein the expression of the dominant negative form of RbAp48 is spatially restricted to the forebrain by a CaM Kinase IIa promoter and wherein the expression of the dominant negative form of RbAp48 is controlled by tetracycline-controlled transcriptional activation. Also provided are methods for evaluating in the transgenic mouse the potential therapeutic effect of an agent for slowing, inhibiting or preventing age-related memory decline in a mammalian subject.

Abstract: Techniques for obtaining a frequency standard using the crystal field splitting frequency of nitrogen vacancy center in diamond are disclosed. In certain exemplary embodiments, a microwave field is applied to the diamond and optically exciting the diamond under green light. The photoluminescent response of the diamond is measured by a photodetector. The intensity of the photoluminescent response can be used to determine the phase shift between the microwave and the crystal field splitting frequency. The microwave field frequency can be adjusted until the phase shift is below a predetermined threshold, and the microwave frequency can then be output for use as a standard.

Abstract: A method for unsupervised anomaly detection, which are algorithms that are designed to process unlabeled data. Data elements are mapped to a feature space which is typically a vector space d. Anomalies are detected by determining which points lies in sparse regions of the feature space. Two feature maps are used for mapping data elements to a feature apace. A first map is a data-dependent normalization feature map which we apply to network connections. A second feature map is a spectrum kernel which we apply to system call traces.

Abstract: Systems and methods are presented for content extraction from markup language text. The content extraction process may parse markup language text into a hierarchical data model and then apply one or more filters. Output filters may be used to make the process more versatile. The operation of the content extraction process and the one or more filters may be controlled by one or more settings set by a user, or automatically by a classifier. The classifier may automatically enter settings by classifying markup language text and entering settings based on this classification. Automatic classification may be performed by clustering unclassified markup language texts with previously classified markup language texts.
