Nanopositioning of a diamond nanocrystal containing a single NV defect center
, 2009 Precise control over the position of a single quantum object is important for many experiments in quantum science and nanotechnology. We report on a technique for high-accuracy positioning of individual diamond nanocrystals.

The role of histone modifications in transcription regulation upon DNA damage
FEBS Letters, EarlyView.This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

Mechanisms of parasite‐mediated disruption of brain vessels
FEBS Letters, EarlyView.Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Ambiguity Resolution with Precise Point Positioning
, 2014 Ambiguity resolution with PPP aims at effectively reducing the long convergence time. The research in this dissertation explores its potential for both dual-frequency signals and triple-frequency signals. One of the most popular PPP ambiguity resolution strategies with dual-frequency GNSS signals is to first fix the L1/L2 wide-lane ambiguities in the ...
