Structural Control of Dual Emission in Coumarin Fluorophores for Visualizing Protein Droplet Maturation

Angewandte Chemie, EarlyView.
A coumarin‐based dual‐emission fluorophore was designed to visualize the maturation of protein liquid droplets. Upon covalent conjugation to droplet‐forming proteins, ratiometric fluorescence imaging allowed real time monitoring of droplet maturation. This probe is applicable to the analysis of droplet formation and maturation mechanisms, as well as to

Patient‐Mounted Neuro Optical Coherence Tomography for Targeted Minimally Invasive Micro‐Resolution Volumetric Imaging in Brain In Vivo

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Herein, a patient‐mounted neuro optical coherence tomography system that integrates a 5 degrees‐of‐freedom skull‐mounted robot (Skullbot) with a 0.6 mm neuroendoscope for targeted, minimally invasive deep brain imaging, is developed. The system offers high‐resolution imaging with precise deployment, demonstrated through successful tumor imaging in a ...

Modal Tilt/Translate Control and Stability of a Rigid Rotor with Gyroscopics on Active Magnetic Bearings

International Journal of Rotating Machinery, 2012
Most industrial rotors supported in active magnetic bearings (AMBs) are operated well below the first bending critical speed. Also, they are usually controlled using proportional, integral and derivative controllers, which are set up as modally uncoupled
