Allosteric Regulation of Photophysics and Binding in Oxazine‐macrocycle Complexes at Single‐molecule Resolution

open access: yesAngewandte Chemie, EarlyView.
This work explores the interactions between the oxazine dye ATTO655 and two macrocyclic hosts using optical (single‑molecule) spectroscopy. Although ATTO655 forms a classical inclusion complex with cucurbit[8]uril (CB8), its interaction with p‑sulfonatocalix[4]arene (sCX4) leads to the formation of dim exclusion complexes.

Variations in blinking bahaviour during soft lens wear [PDF]

open access: yes, 1984
The change in blinking behaviour following the fitting of soft contact lenses was monitored in seven subjects. The mean blink rate increased from 12.1 blinks/minute to 20.3 despite all subjects achieving comfortable all day wear. there was no evidence of

Cerebral control of winking before and after learning: An event‐related fMRI study

open access: yesBrain and Behavior, 2019
Introduction The main purpose of this study was to investigate the cerebral areas responsible for winking by observing the activation pattern and learning effects on cerebral cortices by comparing differences in activation pattern during winking before ...

Accuracy of blinking-off quantum yield retrieval. [PDF]

open access: yes, 2014
Extracted blinking-off quantum yields are plotted against a range of input yields used in a series of simulated PALM data sets. Those simulated data sets were generated using parameters displayed in Table S1 (except for the varying blinking off input ...

Dynamic Regulation of Endogenous Transcription Factor Hubs at Single‐Molecule Resolution

open access: yesAdvanced Science, EarlyView.
This study combines single‐molecule microscopy and genome editing to characterize the dynamic behaviors of endogenous oncofusion transcription factor EWS::FLI1 in Ewing sarcoma cells. EWS::FLI1 forms neomorphic hubs that dynamically assemble and dissolve. The hubs are regulated during mitosis, by RNA, and by specific chemicals.

Theory and effectiveness analysis of dual-aircraft formation active cancellation slow synchronous blinking jamming

open access: yesAIP Advances, 2023
Dual-aircraft formation slow synchronous blinking jamming is standard for jamming monopulse tracking. However, the jamming signal ratio (JSR) of slow synchronous blinking jamming is low and fluctuant in a dynamic jamming scenario, which leads to a poor ...

The effect of hard lens wear on blinking behaviour [PDF]

open access: yes, 1984
The blinking behaviour of 7 subjects was examined under experimentally controlled conditions before and after hard contact lens fitting. Even after comfortable all day wear had been achieved, the mean blink rate increased from 15.5 blinks/min to 23.2 ...

Non-Convergence of Blinking Timescale of Twelve-Faceted Perovskite Nanocrystals Observed through Scanning Fluorescence Correlation Spectroscopy (sFCS) Study [PDF]

open access: yes
Single-particle photoluminescence (PL) measurements have been extensively utilized to investigate the charge carrier dynamics and recombination processes in quantum dots (QDs). Among these techniques, single dot blinking studies are effective for probing
