Abstract: Polypeptides with biophysical properties such as solubility, stability, high expression, monomericity, binding specificity or non-aggregation, including monomeric human heavy and light chain variable domains (VHs and VLs), are identified using a high throughput method for screening polypeptides, comprising the steps of obtaining a phage display library, allowing infection of a bacterial lawn by the library phage, and identifying phage which form larger than average plaques on the bacterial lawn. Sequences of monomeric human VHs and VLs are identified, which may be useful for immunotherapy or as diagnostic agents. Multimer complexes of human VHs and VLs are also identified. The VHs and VLs identified may be used to create further libraries for identifying additional polypeptides. Further, the VHs and VLs may be subjected to DNA shuffling to select for improved biophysical properties.

Abstract: An optical sensor includes pixels. Each pixel has a photodetector. A readout circuit performs a process over an exposure time where the photodetector is connected to a reverse bias voltage supply to reset a voltage across the photodetector, and the photodetector is disconnected from the reverse bias voltage supply until that the voltage across the photodetector decreases in response to received ambient light. An ambient light level is then determine an based on a number of times the voltage across the photodetector is reset over the exposure time.

Abstract: Various implementations include an anchoring device including a tubular body and at least one anchor. The at least one anchor extends along an opening between a first axial end and a second axial end of the opening. The at least one anchor includes a shape memory material. The at least one anchor is movable from a retracted position to an extended position by either increasing the temperature of the anchor above an austenite finishing temperature or decreasing the temperature of the anchor below a martensite finishing temperature.
