1. OpenSTED: Inexpensive and open-source implementation of Dynamic Intensity Minimum (DyMIN) for Stimulated Emission Depletion (STED) microscopy

   https://doi.org/10.1364/NTM.2021.NW4C.3  

   Meyer, Stephanie A.; Siemens, Mark E.; Gopinath, Juliet T.; Restrepo, Diego; Gibson, Emily A. (January 2021, Biophotonics Congress 2021)

   The DyMIN method reduces photobleaching, a problem in STED microscopy. Labs implementing custom-built STED microscopes would greatly benefit from DyMIN capabilities. We present an inexpensive, open-source version utilizing an FPGA and multiplexer.

5. Spatio-Temporal Expanding Distance Asymptotic Framework for Locally Stationary Processes

   https://doi.org/10.1007/s13171-020-00213-4  

   Chu, Tingjin; Liu, Jialuo; Zhu, Jun; Wang, Haonan (January 2020, Sankhya A)

   Spatio-temporal data indexed by sampling locations and sampling time points are encountered in many scientific disciplines such as climatology, environ- mental sciences, and public health. Here, we propose a novel spatio-temporal expanding distance (STED) asymptotic framework for studying the proper- ties of statistical inference for nonstationary spatio-temporal models. In particular, to model spatio-temporal dependence, we develop a new class of locally stationary spatio-temporal covariance functions. The STED asymp- totic framework has a fixed spatio-temporal domain for spatio-temporal pro- cesses that are globally nonstationary in a rescaled fixed domain and locally stationary in a distance expanding domain. The utility of STED is illus- trated by establishing the asymptotic properties of the maximum likelihood estimation for a general class of spatio-temporal covariance functions. A simulation study suggests sound finite-sample properties and the method is applied to a sea-surface temperature dataset.
