An example system includes an interferometer configured to output 3D spatial-spectral data of a sample including an interferometric signal and an optical computation assembly having a spatial light modulator configured to modulate the 3D spatial-spectral data with a modulation pattern. The modulation pattern modulates the interferometric signal along a spectral dimension to select a depth to obtain a sample signal at the selected depth and modulates the interferometric signal along a first spatial dimension to create a waveform to facilitate phase extraction. The system further includes a detector configured to detect 2D spatial data of the sample. The system further includes a processor coupled to a memory, the processor configured to process the 2D spatial data to extract phase information of the sample.

Abstract: Some aspects of the present disclosure are related to articles for measuring electrical signals internal to a subject, e.g., of the gastrointestinal tract (GI tract). The articles, in some embodiments, are ingestible and/or implantable. In some embodiments, the articles comprise a substrate comprising a plurality of electrodes, the substrate having a Young's elastic modulus of greater than or equal to 0.01 MPa and less than or equal to 200 MPa. In some such cases, the Young's elastic modulus of the substrate facilitates elastic recoil of the substrate such that at least a portion of the plurality of electrodes contact a surface of a tissue at the location internal to the subject (e.g., the GI tract) and thus facilitate measurement of electrical signals at the location internal to the subject. Other aspects are related to methods of using the articles, for example, to monitor electrical signals from the location internal to the subject.

Abstract: This application relates to the technical field of confocal microscopy measurement, and provides a dark-field confocal microscopy measurement apparatus and method based on multi-fractional angular momentum demodulation. The apparatus includes a modulated illumination module and a signal collection and demodulation module. The modulated illumination module obtains vortex light with different fractional orders through modulation using vortex phase patterns with different fractional orders, so as to scan a to-be-measured sample. The vortex light with different fractional orders irradiates the to-be-measured sample and is reflected out. The signal collection and demodulation module collects the reflected light and generates dark-field images, and finally performs cross-correlation processing on the dark-field images generated under the vortex light with different fractional orders, to obtain high SNR data.

Abstract: A method and system that utilizes an admissible heuristic to determine the fastest-path between two points on a road map is disclosed. The method and system are based in part on a set of separators disposed on the map and represented by line segments, either independent or organized into hierarchical tree structures and based on recursive spatial subdivision. A preprocessing step computes a vector of values per road junction based on the separators that is then stored with the map and used to efficiently compute a high-quality heuristic to be used at a query stage. The heuristic scales well to any map size, resulting in a very efficient determination of fastest-path queries between points at all distances. The implementation is economically feasible and the resulting query speeds are significantly faster than other known heuristics and other state-of-the-art systems used for computing fastest-paths on maps.

Abstract: The present invention relates to a method of reducing blind decoding attempts by a User Equipment (UE) in a telecommunication network. The method comprises configuring a Search Space (SS) configuration to the UE. A Base Station (BS) signals one of a subset of Aggregation Levels (ALs) to be monitored based on channel quality of the UE and an associated time period, and a value of multiplication factor (k) and an associated time period. The UE iteratively monitors a Physical Downlink Control Channel (PDCCH) on the ALs signalled by the BS till the UE stops receiving a new configuration. The UE performs one of adopting an original configuration, requesting the BS for a new configuration, utilizing a default configuration or utilizing an original configuration.
