Current lithography approaches underpinning the fabrication of microfluidic devices rely on UV exposure of photoresists to define microstructures in these materials. Conventionally, this objective is achieved with gas discharge mercury lamps, which are capable of producing high intensity UV radiation. However, these sources are costly, have a comparatively short lifetime, necessitate regular calibration, and require significant time to warm up prior to exposure taking place. To address these limitations we exploit advances in solid state sources in the UV range and describe a fast and robust wafer-scale laboratory exposure system relying entirely on UV-Light emitting diode (UV-LED) illumination...

Shoulder range of motion (ROM) in throwing athletes relies on a balance of mobility and stability in order to maintain proper function and health. Prior research has reported that deficits in internal rotation greater than 20 degrees, decreases in total arc of motion greater than 5 degrees when compared to the contralateral side, and decreases in horizontal adduction greater than 16 degrees have all been identified as factors that could lead to throwing related injuries.(1) Due to the increased risk of injury associated with ROM deficits, it is important for clinicians to be cognizant of how to most effectively treat these issues...

Urban Bitenc
Deformable mirrors (DMs) are used in adaptive optics for correcting optical aberrations: the DM surface can be deformed to compensate for them. Recently we reported the results on investigation of the stability of Alpao DMs, i.e. how accurately a DM surface shape can be maintained over minutes and hours without any optical feed-back. We observed a creep behavior of the DM surface and we presented a proof-of-concept software compensation for it, showing that very high stability is achievable. In this paper we develop a generalized creep compensation method that covers a wide range of DM use-cases and compensates for 90% - 95% of the creep observed...
