Hypothalamus Regulates Anabolic Metabolism of Articular Cartilage Superficial Chondrocytes through PGE2 Skeletal Interoception

Advanced Science, EarlyView.
Hypothalamus sympathetic norepinephrine inhibits regeneration of articular cartilage. Mechanical loading on bone during animal activity elevates PGE2 skeletal interoception to promote an anabolic renewal of the superficial membrane by downregulation of norepinephrine for articular cartilage proper thickness and integrity.

Piezoresistive Effect: A New Concept for Hearing Aids

Advanced Science, EarlyView.
An MXene/PVA sound sensor utilizing piezoresistive effects has been proposed with a detection limit of 60 dB and a frequency response of 20–4000 Hz, which is comparable to the performance of commercial hearing aids. By combining the sensor with machine learning, the accuracy rate of voiceprint recognition of wildlife conservation can reach up to 99 ...

Enhanced Broadband Acoustic Absorption in Commercial Foam via Multiwall Carbon Nanotube‐Induced Pore Reconstruction

Advanced Science, EarlyView.
A simple to multiscale structure transition happens when a commercial porous foam is filled with multiwall carbon nanotubes with high aspect ratio. For an acoustic absorber with a porous material, the loading of multiwall carbon nanotubes can significantly improve its specific surface area while preserving its thickness and high porosity, thus enables ...

Toward Enhanced Biomimetic Artificial Visual Systems Based on Organic Heterojunction Optoelectronic Synaptic Transistors

Advanced Electronic Materials, EarlyView.
An optoelectronic synaptic transistor based on core‐multi‐shell quantum dots and Pentacene achieves a recognition capability under different light intensities that closely resembles that of the human eye. Under optimal light intensity, the recognition accuracy for the MNIST dataset can reach 91.52%.

Tailoring Dynamic Synaptic Plasticity in FeTFT Optoelectronic Synapse for Associative Learning

Advanced Electronic Materials, EarlyView.
A novel optoelectronic synaptic device based on ferroelectric thin‐film transistors (FeTFTs) is proposed to achieve dynamic synaptic plasticity. The weight range is dynamically regulated by photoelectric cooperation, demonstrating the ability to simulate complex biological behaviors such as classical conditioning experiments, light adaptive behavior ...

Detection of Auditory Brainstem Response Peaks Using Image Processing Techniques in Infants with Normal Hearing Sensitivity [PDF]

arXiv
Introduction: The auditory brainstem response (ABR) is measured to find the brainstem-level peripheral auditory nerve system integrity in children having normal hearing. The Auditory Evoked Potential (AEP) is generated using acoustic stimuli. Interpreting these waves requires competence to avoid misdiagnosing hearing problems.
