Abstract: A method, a network device, and a non-transitory computer-readable storage medium are described in relation to a secure operations, administration, and management (OAM) for remote networks service. The service may categorize performance metric (PM), fault metric (FM) data, and other types of data associated with a virtualized network device of a private network and provide such data to an OAM system of an operator network via a blockchain network or not based on the categorization. The OAM system may also manage orchestration and maintenance of the private network including the virtualized network device based on configuration data transmitted via the blockchain network or not. The virtualized network device may be a radio access network device, a core network device, or an edge server device. The secure OAM for remote networks service may also store service assurance policies as a smart contract in the blockchain network.

Abstract: An imaging assembly and processing system that includes a sample platform having a target region which can hold a sample, where the sample can be marked with fluorescent or phosphorescent markers. The imaging assembly can have an excitation light module proximate to the sample platform that emits light to excite the markers, and a lens module positioned to receive emission light from excited markers in target region. At least one series filter assembly or interference filter can be arranged in front of, behind, or both in front of and behind the lens module. The assembly includes a light sensor and a processor and imaging module configured to process data captured by the light sensor. Images of the sample are generated based on the emission light from the sample that transmit through and are filtered by the lens assembly and series filter assembly or interference filter.

Abstract: Methods, apparatuses, and systems for imaging biological/chemical samples are provided. A calibrated imaging system can allow a user to obtain an optimal focus setting (position) for any effective distance (e.g. a zoom setting). The optimal focus can be determined from a functional approximation that defines a relationship between effective distance and focus setting. A user can input a size, and an imaging system can determine the appropriate effective distance and focus. An imaging system can also determine a size based on any effective distance. A flat-field correction can also be determined for any effective distance or size.

Abstract: Systems and methods for substantially simultaneously exciting a fluorescently labeled specimen and capturing fluorescent light emitted therefrom using a smartphone, tablet, or similar mobile computing device, are disclosed herein. The system includes a light-emitting diode (“LED”) light source coupled with the smartphone to excite the specimen and an imaging device coupled with the smartphone to capture fluorescent light emitted from the specimen. The system further includes a hood adapted to be coupled with the smartphone that has an excitation filter configured to produce a first wavelength of electromagnetic radiation to strike the specimen when light from the LED light source passes through it and an emission filter configured to receive the light emitted from the specimen and to produce a second wavelength of electromagnetic radiation to be captured by the imaging device.

Abstract: An adaptor is designed as an accessory to an ultraviolet transilluminator for the excitation of fluorescent molecules or labels in a planar array of biochemical samples such as a two-dimensional electrophoresis gel to enable the emissions resulting from the excitation to be detected and quantified. The adaptor is constructed to overlay the transilluminator and contains both a fluorescent dye that upon excitation by ultraviolet light emits light in the visible spectrum, and a conditioning substance that selects a portion of the wavelength band of the visible light produced by the fluorescent dye. The adaptor converts the ultraviolet light from the transilluminator to visible light while limiting the emissions reaching the detector to those that emanate from the sample. By the use of this adaptor, the transilluminator is adapted for use with samples labeled with dyes that are excitable by visible light and avoids exposure of the samples and the user to ultraviolet light.

Abstract: Images of two-dimensional chromatograms or other sample arrays are formed on a scanning instrument that utilizes a line of illumination light that sweeps the length of the array either by moving across the array or by the array moving relative to the light, in either case scanning the entire two-dimensional array with a unidirectional pass of the moving component. The use of a CCD equipped with time delay integration allows the instrument to form an enhanced image.

Abstract: The optical imaging of two-dimensional solute zone arrays in electrophoresis gels is corrected for nonuniformities in the optical system such as those arising from the light source or from light dispersion underneath the gel. The correction is achieved by the use of a reference plate that responds to a light source uniformly along its length and width by being either uniformly light absorptive or uniformly light transmissive, or by emitting light upon excitation. Thus, any nonuniformities or deviations in the image of the reference plate arise only from nonuniformities or deviations within the optical system. Analogous corrections are made in other two-dimensional assay images, such as microarrays and microtiter plates.
