LADRC-Based Magnetic Field Measurement Method for a Nuclear Magnetic Resonance Rotation Sensor
Applied Sciences, 2021 Magnetic field measurement is fundamental to nuclear magnetic resonance rotation sensors (NMRRS). A phase-locked loop (PLL)-based measurement with two nuclear isotopes is commonly applied to observe the magnetic field.

Optimization of CEST MRI Reporter Protein Design Using Cation‐Pi Networks
Chemistry – A European Journal, Volume 32, Issue 28, 25 July 2026.A novel engineering approach can produce reporter proteins for cell and viral therapy tracking with unique magnetic resonance imaging (MRI) signatures, detectable with chemical exchange saturation transfer (CEST). We discover how cation‐π interactions between amino acid groups can help us fine‐tune magnetic resonance properties for noninvasive ...

Laser &Photonics Reviews, Volume 20, Issue 14, 22 July 2026.This work demonstrates a high‐fidelity stability transfer from an optical reference to a high‐repetition‐rate microcomb using a mode‐locked laser bridge. By employing electro‐optic sampling timing detection, femtosecond‐level synchronization and 10−18‐level fractional frequency stability are achieved.

Single Cell Mechanics in Disease Progression
Small Science, Volume 6, Issue 7, July 2026.Cells transmit distinct mechanical forces through ECM adhesion and cell–cell junctions and actomyosin‐generated traction forces are transmitted to the substrate through integrin‐based focal adhesions. Mechanical signals are further transmitted to the nucleus via the LINC complex, connecting the cytoskeleton to the nuclear lamina. These forces integrate

Chemistry – An Asian Journal, Volume 21, Issue 12, 26 June 2026.LiF grows on diindenoperylene not as a smooth film but as sparse, inhomogeniety associated nanoparticles that evolve stochastically toward full coverage, perturbing the interface while leaving the organic lattice intact. ABSTRACT Small‐molecule π$\pi$‐conjugated semiconductors provide an ordered platform for probing interfacial mechanisms in organic ...

Reference Spur Reduction Techniques for a Phase-Locked Loop
IEEE Access, 2019 This paper presents the reference spur reduction techniques for an analog phase-locked loop (PLL). A simple leakage compensation loop is proposed, which cancels the leakage current of the PLL loop filter with a negligible power overhead.
