We present a protocol for the amplification and distribution of a one-time-pad cryptographic key over a point-to-multipoint optical network based on computational ghost imaging (GI) and compressed sensing (CS). It is shown experimentally that CS imaging can perform faster authentication and increase the key generation rate by an order of magnitude compared with the scheme using computational GI alone. The protocol is applicable for any number of legitimate user, thus, the scheme could be used in real intercity networks where high speed and high security are crucial.

Pudendal neuropathy is a cause of pelvic pain, specifically pudendal neuralgia. The pudendal nerve is related to sensory, motor, and autonomic functions. We present the case of a 41-year-old man who suffered from chronic pelvic pain.

Accurately assessing saltiness perception in solid foods is essential for the development of low-sodium foods that maintain saltiness despite possessing a lower sodium content. This study aimed to develop a practical system for evaluating human-perceived saltiness during oral processing, particularly when food was initially placed on the tongue. As a basis for system design, sensory evaluations demonstrated that higher local salt concentrations (inhomogeneous distribution) on the tongue significantly enhanced perceived saltiness intensity compared to a homogeneous distribution, despite equal total salt content.

At present, flexible sensors are a hot spot in research and experimental development, but the research on flexible sensors that can be used for human motion monitoring still needs to be deepened. In this work, the green material cellulose acetate (CA) was used as the matrix material, the film was made by electrospinning, crushed by a cell grinder and sodium alginate (SA) was added to promote the uniform dispersion of nanofibers in water, and then methyltrimethoxysilane (MTMS) and MXene nanosheet dispersion were added to make it hydrophobic and good conductivity, and the aerogel precursor solution was prepared, and then the CA/SA/MTMS/MXene aerogel with directional holes was prepared by directional freeze-drying. As a flexible sensor material, it can be used for human wear, monitoring the electrical signals generated by the movement of human joints and other parts, and can still maintain a current of about 0.

Strain sensors have received considerable attention in personal healthcare due to their ability to monitor real-time human movement. However, the lack of chemical sensing capabilities in existing strain sensors limits their utility for continuous biometric monitoring. Although the development of dual wearable sensors capable of simultaneously monitoring human motion and biometric data presents significant challenges, the ability to fabricate these sensors with geometries tailored to individual users is highly desirable.

Surface electromyography (sEMG) holds great potential in walking function evaluation. Compressed sensing (CS) leverages the sparsity of signals to decrease the number of samples required. In this study, a sEMG CS algorithm for spinal cord injury (SCI) patients based on regularized orthogonal matching pursuit (ROMP) was introduced.
