Ectopic pancreas (EP) is most commonly located in the upper gastrointestinal tract, particularly in the stomach. Malignant transformation of EP is exceptionally rare, and due to its very low incidence, the response to drug therapy and overall prognosis remain poorly understood. This report presents...

We investigate experimentally the state bistability driven by current or feedback in a 1550 nm vertical-cavity surface-emitting laser (1550 nm-VCSEL) with negative optoelectronic feedback (NOEF). The results show that through continuously varying the controlled parameters such...

To address the challenges of rapid production decline and low recovery of shale oil wells, it is imperative to supplement formation energy and explore innovative development methods. Compared with conventional waterflooding, CO2 exhibits superior injectivity and miscibility with crude oil, making it...

We have experimentally demonstrated and characterized the generation of tunable and ultra-broadband microwave frequency combs (MFCs) based on a slave laser (SL) subject to regular pulse injection from a current modulated master laser (ML). Under modulation frequency <italic>f<sub>m</s...

The polarization bistability (PB) features in a 1550&#x00A0;nm vertical-cavity surface-emitting laser (1550&#x00A0;nm-VCSEL) subject to variable polarization optical injection (VPOI) are experimentally investigated. We have investigated the influence of polarization angle <inline-formula&...

In this work, a novel optoelectronic oscillator (OEO) structure is proposed for generating widely tunable photonic microwave. In this structure, an optical injection semiconductor laser (OISL) functions as an active tunable microwave photonic filter (MPF). Through controlling the injection power and...

Pork cutting is a very important processing in promoting economic appreciation across the swine business chain. The goal of this research is to determine the proportion and weight of meat cuts, as well as to analyze the effects of carcass weight, sex and breed composition on meat cuts. Simultaneousl...

The principle of genomic selection (GS) entails estimating breeding values (BVs) by summing all the SNP polygenic effects. The visible/near-infrared spectroscopy (VIS/NIRS) wavelength and abundance values can directly reflect the concentrations of chemical substances, and the measurement of meat tra...

Taking the broadband chaotic output from a weak-resonant-cavity Fabry&#x2013;Perot laser diode (WRC-FPLD) under filtered feedback as a chaotic entropy source, we propose and experimentally demonstrate a scheme for generating fast physical random bits (PRBs) at a rate up to 240 Gbits&#x002F;s...
