Aiming at the demand for high-capacity wireless-fiber link, the coupling efficiency of Laguerre Gaussian (LG) vortex beam into parabolic fiber under atmospheric turbulence is first investigated. The coupling model is established based on vortex mode analysis in free space and fiber. Effects of turbu...

Aiming at the propagation of asymmetric vortex beam, we investigate the spreading and wander characteristics of asymmetric Bessel-Gaussian beam in oceanic turbulence. Based on the cross-spectral density and Wigner distribution function of beam field, the theoretical expressions of spreading factor a...

IntroductionMotor imagery-based brain-computer interfaces (BCIs) are a technique for decoding and classifying the intention of motor execution, solely based on imagined (rather than executed) movements. Although deep learning techniques have increased the potential of BCIs, the complexity of decodin...

Honey-processed Glycyrrhiza (G.) uralensis has a wide range of pharmacological and medicinal effects. The processing of G. uralensis with honey has been associated with an increase in the content of pharmacologically active components and the enhancement of tonic effects. However, the mechanism unde...

We present a filtering algorithm based on empirical mode decomposition (EMD) for the data demodulation of the fiber-optic surface plasmon resonance (SPR) sensor. After data preprocessing by the EMD-based filtering algorithm, three methods are compared to obtain the valley wavelength of the SPR. The...

Aphelinus asychis is an important aphid endoparasitoid. Under field and greenhouse conditions, high temperature is one of the factors limiting the application of A. asychis for biological pest control. To explore the potential role of transient receptor potential (TRP) channels and heat shock protei...

Succinate dehydrogenase (SDH)-deficient gastrointestinal stromal tumors (GISTs) are located exclusively in the stomach with a predilection for young adults and children. Occurrences of SDH-deficient GISTs in the extra-gastric location are rather rare. Herein, we presented an unusual esophageal case...
