‘In silico labelling’: Exploring the biological landscape at the nanoscale using intelligent multimodal optical microscopy

Journal of Microscopy, Volume 304, Issue 1, Page 41-50, October 2026.
Abstract Multimodal optical microscopy has recently converged with artificial intelligence (AI) to enable in silico labelling—the computational prediction of fluorescence‐like molecular contrast from label‐free measurements. Fluorescence plays a crucial role in linking microscopy and spectroscopy at molecular level, enabling image formation by means of

Quantitative Cherenkov‐excited fluorescence emission dosimetry for HDR Co‐60 brachytherapy: Calibration and planar validation against TPS

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Accurate dose verification in High‐Dose‐Rate (HDR) brachytherapy presents a significant challenge due to steep dose gradients and the absence of beam collimation. Conventional quality assurance (QA) methods typically rely on point detectors or film‐based techniques, which lack the capability to provide real‐time, full‐field ...

Quantum-enhanced imaging with SPAD array cameras

, 2023
(English) Entangled photon pairs can enhance optical imaging capabilities. Phase imaging allows detecting fine detail of transparent samples without potentially invasive fluorescent labelling, and here entanglement enables a higher signal-to-noise ratio (SNR) than possible with only classical light. Spatial correlations from spontaneous parametric down

Compact CMOS active quenching/recharge circuit for SPAD arrays [PDF]

International Journal of Circuit Theory and Applications, 2015
SummaryAvalanche diodes operating in Geiger mode are able to detect single photon events. They can be employed to photon counting and time‐of‐flight estimation. In order to ensure proper operation of these devices, the avalanche current must be rapidly quenched, and, later on, the initial equilibrium must be restored.

One‐Time Top‐Dressing of Panicle Nitrogen Fertilizer Maintains High Grain Yield and Nitrogen Use Efficiency of Rice in South China

Food and Energy Security, Volume 15, Issue 5, September/October 2026.
ABSTRACT Optimized nitrogen (N) management for rice production typically involves multiple split applications of N fertilizer to enhance rice yield and nitrogen use efficiency (NUE). However, China's rural labor shortage highlights the need to reduce the frequency of fertilizer applications to minimize labor inputs and improve production efficiency.
