Visual inspection provides precise intraoperative evaluation of tibial slope during unicompartmental knee arthroplasty

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Accurate reconstruction of the posterior tibial slope (PTS) is essential for successful unicompartmental knee arthroplasty (UKA), yet intraoperative assessment remains challenging without advanced navigation tools. This study evaluated the accuracy of visual intraoperative assessment of PTS changes after tibial resection.

Olfactory Bulb Volume and Function Recovery in Eosinophilic Chronic Rhinosinusitis

open access: yesThe Laryngoscope, EarlyView.
This study investigated perioperative changes in olfactory bulb volume (OBV) in patients with eosinophilic chronic rhinosinusitis using high‐resolution 3T MRI. Postoperative increases in OBV were associated with improvements in olfactory identification, suggesting a potential link between olfactory bulb structural plasticity and functional recovery ...

Optical‐to‐Microcomb Stability Transfer for Ultrastable Timing and Microwave/Millimeter‐Wave Generation

open access: yesLaser &Photonics Reviews, EarlyView.
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.

Static and Dynamic Analysis of Porous Gas Bearings Lubricated With Air, Refrigerant R‐134a, Helium and Hydrogen

open access: yesLubrication Science, EarlyView.
ABSTRACT Porous gas bearings (PGBs) enable high‐speed, oil‐free operation in modern rotating machinery. This study develops a coupled thermo‐hydrodynamic (THD) model for a cylindrical porous gas bearing lubricated with four working fluids—air, R‐134a, helium and hydrogen.

A PLP‐SEC Investigation of Di(Ethylene Glycol) Methyl Ether Methacrylate Radical Polymerization Propagation Kinetics in Solution

open access: yesMacromolecular Reaction Engineering, EarlyView.
The propagation rate coefficient of di(ethylene glycol) methyl ether methacrylate exhibits the same temperature dependency but is a factor of 12 higher in aqueous solution compared to bulk. Smaller increases are observed in ethanol and ethanol/water mixtures, with the value of the rate coefficient decreasing as the monomer concentration in solution is ...
