Introduction: Athletic peak performance is increasingly focused on cognitive and mental factors. In the current study, cognitive performance was measured by neurophysiological responses in elite Junior-A hockey players.
Methods: Neurophysiological brain vital signs were extracted from event-related potentials (ERPs) to evaluate auditory sensation (the N100), basic attention (the P300), and cognitive processing (the N400).

Article Synopsis
- Intraoperative neuromonitoring (IONM) is valuable in thyroid/parathyroid surgeries and aims to assess vocal cord paralysis (VCP) through variations in recurrent laryngeal nerve (RLN) amplitudes.
- A study involving 728 RLNs found that specific amplitude ranges (particularly V2 at 117-216 μV) effectively predicted VCP with high sensitivity and specificity.
- The findings suggest that measuring V2 amplitudes can serve as a reliable method to predict postoperative VCP, especially when initial vagus nerve exposure is limited.
This paper demonstrates a customized quartz tuning fork (QTF) coated with the titanium carbide (TiCT) MXene film that can effectively enhance the sensitivity of light-induced thermoelastic spectroscopy (LITES). The MXene film is coated at the root of the customized QTF. The film area is proven to have little impact on resonance frequency, bandwidth, quality factor, and amplitude of the second harmonic signal (2) based on the fundamental flexural mode.
View Article and Find Full Text PDFFiber-optic vibration sensors have been studied widely owing to their anti-electromagnetic interference, corrosion resistance, and ease of integration and distribution. Previous reports primarily focused on the frequency detection of vibration signals. However, the amplitude sensitivity, noise-equivalent amplitude (NEA), and stability determine the sensing precision and accuracy of the device.
View Article and Find Full Text PDFDistributed acoustic sensing (DAS) is a technology that uses optical fiber as a sensing unit to detect external vibration signals. Due to the high resolution and high sensitivity of DAS, it has great application potential in the detection of vibration events. However, high detection performance will bring limitations to DAS in multi-source detection.
