Theoretical formulation and experimental validation of brightness evaluation using digital cameras

open access: yesResults in Optics, 2021
In this study, we formulated the brightness relation of two digital photos captured by a single digital camera and verified it experimentally. The experimental results suggested that the used zoom lens has an intrinsic error, thereby making accurate ...

An Optimized Colorimetric Readout Method for Lateral Flow Immunoassays

open access: yesSensors, 2018
Despite its broad penetration of various markets, the quantitative lateral flow immunoassay (LFIA) suffers from sensitivity issues in some cases. To solve this problem, an optimized colorimetric readout method for LFIA quantification is proposed in this ...

Quantifying the heterogeneity of macromolecular machines by mass photometry

open access: yesbioRxiv, 2019
Sample purity is central to in vitro studies of protein function and regulation, and to the efficiency and success of structural studies using techniques such as x-ray crystallography and cryo-electron microscopy (cryo-EM).

Simultaneous Electrophysiology and Fiber Photometry in Freely Behaving Mice

open access: yesFrontiers in Neuroscience, 2020
In vivo electrophysiology is the gold standard technique used to investigate sub-second neural dynamics in freely behaving animals. However, monitoring cell-type-specific population activity is not a trivial task.

Variable Stars in the Globular Cluster M5. Application of the Image Subtraction Method [PDF]

open access: yes, 1999
We present $V$-band light curves of 61 variables from the core of the globular cluster M5 obtained using a newly developed image subtraction method (ISM). Four of these variables were previously unknown.
