Abstract: Described herein are methods for imaging a fluorescent bioassay (including a substrate, such as dispersed cellular sample, exposed to one or more exogenous fluorophore and/or fluorescent probe that accumulate in a structure of interest). The bioassay can be excited with Type-C ultraviolet (UVC) light produced by one or more light emitting diode (LED). The UVC can have a center wavelength that causes emission by the fluorescent bioassay. A digital optical device can collect a signal emitted from the fluorescent bioassay in response to the excitation. The methods relate in particular to Microscopy with Ultraviolet Surface Excitation (MUSE) imaging.

Abstract: Described herein are systems and methods for improving light-sheet microscopy with cost-effective and simplified components. Such cost-effective and simplified components can be implemented in a light focusing system, a light generation system, and/or in imaging system. The light focusing system can be improved by attaching a voice coil motor to a focusing lens to increase the imagable field of view. The light generation system can be improved with a multimode laser diode to increase the uniformity of the beam profile and to increase the usable optical power. The imaging system can be improved by using a fluid chamber with positive cylindrical optical window for minimizing spherical aberrations.

Abstract: Rapid and data-efficient training of an artificial intelligence (AI) algorithm are disclosed. Ground truth data are not available and a policy must be learned based on limited interactions with a system. A policy bank is used to explore different policies on a target system with shallow probing. A target policy is chosen by comparing a good policy from the shallow probing with a base target policy which has evolved over other learning experiences. The target policy then interacts with the target system and a replay buffer is built up. The base target policy is then updated using gradients found with respect to the transition experience stored in the replay buffer. The base target policy is quickly learned and is robust for application to new, unseen, systems.
