Synergistic Enhancement of Modified‐PVDF Humidity Sensitivity via Chemical Adsorption‐Ionic Conductivity and its Application in Intelligent Powered Air‐Purifying Respirator

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The study developed a PVDF/SiO2 humidity sensor with superhydrophobic properties and integrated the humidity sensor into the intelligent powered air‐purifying respirator (IPAPR) for breath monitoring. Coupled with the Gated Recurrent Unit (GRU) machine learning prediction algorithm, it enables feedforward control of the fan to achieve respiratory ...

Hypervision Proton Surgery: The Future Direction of Proton Therapy

open access: yesiNew Medicine, EarlyView.
ABSTRACT Proton beams provide unique physical advantages characterized by a low entrance dose, negligible exit dose, and a sharp Bragg peak, which enable superior sparing of normal tissues and support safe dose escalation for improved tumor control. However, conventional photon‐based fractionation remains widely used in proton therapy, where prolonged ...

Open or closed: Experience of head and neck radiotherapy masks – A mixed‐methods study

open access: yesJournal of Medical Radiation Sciences, Volume 72, Issue 1, Page 74-84, March 2025.
Patients with head and neck cancer received radiotherapy alternately with an open and a closed mask. The closed mask was perceived as more confining and restrictive, but it was also considered to make it easier to quickly achieve the correct position, while the open mask was perceived as less stable, although it reduced the feeling of claustrophobia ...
