COMPUTER VISION FOR REAL-TIME SEGMENTATION OF FLUORESCENT BIOLOGICAL IMAGES
A segmentation system processes images of a sample that includes fluorescent entities. The segmentation system applies a threshold image that represents background illumination distinct from fluorescence of target entities to pre-process the images. The segmentation system determines numbers of target entities in pre-processed images and determines whether an estimated number of target entities in the sample meets a threshold certainty. The segmentation system continues to analyze one or more images until the threshold certainty is determined. When the threshold certainty is met, the estimated number of target entities may be used to generate a user interface output (e.g., displaying the pre-processed images and visual indicators of the locations of target entities.

The circuit for sharing current between parallel LED pathways can include a first LED pathway, a first transistor coupled to the first set of LEDs and that can control a first current through the first set of LEDs, and a first measurement node having a first sensed voltage. The circuit can include a second LED pathway, a second transistor coupled to the second set of LEDs and that can control a second current through the second set of LEDs, and a second measurement node having a second sensed voltage. The circuit includes a first differential amplifier and a second differential amplifier, each of which can compare sensed voltage and can apply a voltage to a gate of one of the first and second transistors.

A heat pump that includes a thermoelectric device(s) and a heat sink having a raised portion with a top surface for thermally coupling with a planar face of the thermoelectric device(s). The raised portion of the heat sink includes an outer periphery and a raised central region surrounded by a void region to provide more uniform thermal conductivity when clamped within an assembly. The raised central region is shaped in an any shape corresponding to a shape of uneven thermal conductivity due to clamping pressure applied to the heat sink. The void region can be substantially contiguous and entirely circumscribe the central raised region. The device can optionally include discrete supports formed of a less thermally-conductive material within the void region. The supports can be elastomeric, such as O-rings, and disposed within pockets defined within the void region.

MIXED MODE CATIONIC EXCHANGE CHROMATOGRAPHY LIGANDS BASED ON SUBSTITUTED 2-BENZAMIDO ACETIC ACID STRUCTURES
The subject invention pertains to mixed mode chromatography ligands and chromatography matrices suitable for the purification of proteins from biological sources or biological samples. Methods of making chromatography matrices comprising the disclosed ligands and using the disclosed chromatography matrices are also provided.
A fluorescence detection system, including apparatus and methods, suitable for qPCR and other fluorescence-based analyses. The system may comprise various components, including a stage, an illumination module, a detection module, and an optical relay structure. The stage may be configured to support a sample holder. The illumination module may include one or more discrete light sources configured to produce excitation light. The detection module may be configured to detect fluorescence emission light produced, in response to the excitation light, by a fluorescent sample positioned in the sample holder. The optical relay structure may include a beamsplitter assembly configured to direct the excitation light from the illumination module along an illumination path to the sample holder and to direct the fluorescence emission light from the sample holder along a response path to the imaging module. The system may enhance the quality of excitation light hitting samples in the sample holder, for example, by collimating and/or homogenizing the light.
