Fiber-based sensors, owing to their high flexibility, excellent breathability, and ease of integration into everyday clothing, have the potential to serve as a novel type of wearable electronic device. This paper presents a helical strain-sensing fiber using electromagnetic induction, made from Ecoflex and magnetic nanoparticles. It achieves up to 2485% strain and maintains stable voltage output (max 90 μV) over 2000 cycles. In conclusion, based on this novel intelligent sensing material, we developed a human-machine interaction (HMI) system operable underwater, enabling remote control of a submarine model through hand gestures. This system facilitates real-time gesture interaction, opening new research avenues for the development of wearable HMI systems and Internet of Things technology in the future.

Purpose: Uncertainty persists regarding the optimal mode of mechanical ventilation for laparoscopic perioperative periods. Electrical impedance tomography (EIT) is an effective tool for monitoring and guiding lung-protective ventilation. This study aimed to compare the effects of pressure-controlled ventilation-volume guaranteed (PCV-VG) and volume-controlled ventilation (VCV) on pulmonary ventilation during laparoscopic surgery.

In the semi-airborne frequency-domain electromagnetic (SAFEM) method, the total magnetic intensity (TMI) is derived from the vector synthesis of triaxial inductive magnetic sensors. However, non-orthogonal errors in the sensors introduce measurement inaccuracies. Traditional calibration techniques are unsuitable for induction magnetic sensors because they require either static magnetic field measurements or complex alternating current reference fields.

Environmental stimuli, including the exposure to ultraviolet (UV)-B light, are known to play a role in the modulation of immune-mediated mechanisms in multiple sclerosis (MS). In experimental autoimmune encephalomyelitis (EAE), we have shown that UV-B irradiation ameliorates disease outcome by regulatory T cells (Treg) expansion. Moreover, the UV-B-mediated induction of Treg numbers was also observed in MS.

Background: Cardiac implantable electronic devices (CIEDs) are essential for managing cardiac conditions, but may malfunction due to magnetic fields > 10,000 mG. Roller coasters using linear induction motors (LIMs) generate magnetic fields, yet their potential for electromagnetic interference (EMI) with CIEDs is unclear. This study assesses magnetic field exposure on amusement park rides and examines healthcare provider recommendations.

To investigate the photosynthetic responses of needles with different ages (current-year and annual-year) in to sunflecks along the vertical gradient of canopy, we conducted an experiment at the Changbai Mountain Forest Ecosystem Positioning Station utilizing a canopy tower crane platform. We selected current-year and annual-year needles from the upper (mean height: 23.26 m), middle (16.
