A strategy of RGB-IR dual optical fusion is proposed, that is, each component of multiple color Spaces is detected individually, several channels with the best human detection performance are counted, and the prospects of these channels are fused to obtain the final human detection result. In additi...

Nudibranchs, also known as sea slugs, represent a high species diversity within Heterobranchia (Mollusca, Gastropoda); however, the systematics within this order remain controversial. The mitochondrial genome has been widely used in the phylogenetic reconstruction of mollusks, but the corresponding...

We propose a novel technique for joint modulation format identification and frequency offset (FO) estimation. The linear frequency modulation signal which is obtained by a direct current signal and Fractional Fourier Transform (FrFT) is superimposed on the data symbols to mark and identify the modul...

Rotary drilling has been recognized for its excellent drilling performance in laser drilling. However, there are few studies on the optical path trajectory equations guiding the implementation of laser rotary drilling, which has limited the development of rotary drilling. Here, the paper deduces the...

An image compression-encryption scheme utilizing the combination of fiber specklegram-based compressive sensing (CS) and double random phase encoding (DRPE) was demonstrated. The original image is compressed and encrypted by CS and then re-encrypted by DRPE. The measurement matrices for CS are const...

This study explored the mechanism by which ultrasound (0–180 W) assisted ethanol (25 % and 30 %) enhances the gel properties of egg white gel (EWG). The results showed that ultrasonic treatment (stabilized at 120 W) prominently improved hardness, springiness and water holding capacity (WHC) (approxi...

To reduce the complexity and cost of remote access units (RAUs), colorless transport architecture is preferred in a wavelength-division multiplexing (WDM) system. The wavelength-reuse technique is commonly adopted to realize colorless RAUs. However, in traditional approaches, RAUs employ crystal-bas...

In this article, a precisely controlled, switchable thulium-doped fiber laser (TDFL) with high optical signal-to-noise ratio (OSNR) is proposed and demonstrated. A home-made multimode fiber Bragg grating (MMFBG) with multireflection peaks was used as an optical filter to select the desired lasing ch...

Stroke poses a serious threat to human health, while there are very few drugs that can directly alleviate ischemia/reperfusion injury and improve the prognosis. Studies have shown that small-molecule activators of aldehyde dehydrogenase 2 (ALDH2) have the potential to become novel therapeutic drugs...
