Pulsed stimulated Brillouin microscopy.
Chow DM, Yun SH. Chow DM, et al. Opt Express. 2023 Jun 5;31(12):19818-19827. doi: 10.1364/OE.489158. Opt Express. 2023. PMID: 37381389 Free article.
We verify the theoretical prediction by developing a novel scheme using low duty cycle, nanosecond pulses for the pump and probe. A shot noise-limited SNR over 1000 was measured with a total average power of 10 mW for 2 ms or 50 mW for 200 s integration on water sam …

Magnetohydrodynamic levitation for high-performance flexible pumps.
Matia Y, An HS, Shepherd RF, Lazarus N. Matia Y, et al. Proc Natl Acad Sci U S A. 2022 Jul 19;119(29):e2203116119. doi: 10.1073/pnas.2203116119. Epub 2022 Jul 11. Proc Natl Acad Sci U S A. 2022. PMID: 35858310 Free PMC article.
We use magnetohydrodynamic levitation as a means to create a soft, elastomeric, solenoid-driven pump (ESP). We present a theoretical framework and fabrication of a pump designed to address the unique challenges of soft robotics, maintaining pumping performance under …

Vitreoretinal instruments: vitrectomy cutters, endoillumination and wide-angle viewing systems.
de Oliveira PR, Berger AR, Chow DR. de Oliveira PR, et al. Int J Retina Vitreous. 2016 Dec 5;2:28. doi: 10.1186/s40942-016-0052-9. eCollection 2016. Int J Retina Vitreous. 2016. PMID: 27980854 Free PMC article. Review.
Cut rates of up to 16,000 cuts per minute are already available. New probe designs and pump technology have allowed duty cycle performances of near 100% and improved flow control. ...

Aqueous Humor Dynamics of the Brown-Norway Rat.
Ficarrotta KR, Bello SA, Mohamed YH, Passaglia CL. Ficarrotta KR, et al. Invest Ophthalmol Vis Sci. 2018 May 1;59(6):2529-2537. doi: 10.1167/iovs.17-22915. Invest Ophthalmol Vis Sci. 2018. PMID: 29847660 Free PMC article.
METHODS: One eye of 26 anesthetized adult Brown-Norway rats was cannulated with a needle connected to a perfusion pump and pressure transducer. Pressure-flow data were measured in live and dead eyes by varying pump rate (constant-flow technique) or by modulating …

Origin of SRS-induced beam quality distortion under TMI threshold.
Wang L, Zhang H, Zhong P, Zeng L, Yang B, Xi X, Wang P, Wang X, Xu X. Wang L, et al. Opt Express. 2023 Jun 5;31(12):20237-20243. doi: 10.1364/OE.480995. Opt Express. 2023. PMID: 37381422 Free article.
We're going to differentiate between heat effect and nonlinear effect by duty cycle operation. The evolution of beam quality at different pump duty cycles has been studied based on a quasi-continuous wave (QCW) fiber laser. It is found that even if the Stokes …

McPeck M, Ashraf S, Cuccia AD, Smaldone GC. McPeck M, et al. Respir Care. 2021 Apr;66(4):573-581. doi: 10.4187/respcare.07715. Epub 2020 Sep 23. Respir Care. 2021. PMID: 32967932 Free article.
RESULTS: Variation in inhaled mass was significantly explained by pump flow and duty cycle (R(2) 0.92) and not by nebulizer technology. Duty cycle effects were more apparent at higher pump flow. Vibrating mesh nebulizers failed to nebulize completely i …
