Tea grade evaluation plays an important role in detecting the quality of tea. In this work, we proposed a method for black tea discrimination, which is based on hyperspectral (HSI) technique, chemometric algorithms and data fusion strategies. Standard Normal Variable (SNV) Multiple Scattering Correction (MSC) were used pretreatment HSI-NIR data. Moreover, spectral features catechins, polyphenols soluble sugars extracted separately by Uninformative Elimination (UVE). To improve accuracy...
RNA interference (RNAi)-mediated gene knockdown is a potent approach for studying function. We have previously reported plasmid-based, tamoxifen-inducible system in cultured cells using combined RNAi and Cre-LoxP system. Here, we validate this mouse show that it can be used to suppress the expression of an endogenous (Fgfr2) with high efficiency. transgenic mice carrying U6-ploxPneo-Fgfr2 construct are normal, displaying Fgfr2 transcripts equivalent those wild-type controls, indicating U6...
Back projection algorithm (BPA) and range migration (RMA) are two common approaches for image reconstruction in synthetic aperture radar (SAR) imaging. Imaging is implemented spatial domain frequency domain, respectively these methods often considered to generate the same results. This true normal microwave/millimeter wave SAR imaging systems, since object of interests located far away applied wavelength long. In this case, location most important issue there no impetus with very fine...
We report a mode-locked high-power all-polarization-maintaining Er/Yb-doped large-mode-area fiber oscillator based on bias nonlinear amplifying loop mirror (NALM). The can generate ∼1-nJ femtosecond pulses without dispersion compensation. By inserting Martinez-type compensator to provide normal dispersion, it >10-nJ picosecond dissipative solitons (DSs). measured M2 factors are below 1.5, indicating good beam quality. When the cavity is tuned be ∼0.704 ps2, deliver chirped DSs with an...
The rolling bearing is a key component of the bogie rail train. working environment complex, and it easy to cause cracks other faults. Effective fault diagnosis can provide an important guarantee for safe operation track while improving resource utilization greatly reducing cost operation. Aiming at problem that characteristics vibration data components railway train mechanism model are difficult establish, method long-term faults trains based on Exponential Smoothing Predictive Segmentation...
As a component of crude oils, wax plays an important part in the flowability waxy oils. The deposition waxes poses significant challenge petroleum production. This paper proposes laser-induced voltage (LIV) to measure appearance temperature (WAT). With decreased temperature, peak LIV signal (VP) decreases with greater slope until inflection point (TLIV) after that precipitates from oil. After which, VP changes more slowly. Thus, TLIV is confirmed as WAT. Furthermore, WAT was measured using...
Due to the significant price difference, expensive oils like olive oil are often blended with cheaper edible oils. This practice of adulteration in oils, aimed at increasing profits for producers, poses a major concern consumers. Furthermore, can lead various health issues impacting consumer well-being. In order meet requirements fast, non-destructive, universal, accurate and reliable quality testing oil, oblique-incidence reflectivity difference (OIRD) method combined machine learning...

We report a mode-locked Er/Yb-doped large-mode-area (LMA) fiber oscillator based on nonlinear polarization evolution (NPE), which utilizes linear cavity primarily composed of polarization-maintaining (PM) fibers. The operates at 1.56 µm with fundamental repetition rate 34.47 MHz and has two output ports. One port can deliver high-quality soliton-like pulses pulse duration 325 fs an average power 39.5 mW (corresponding to energy 1.15 nJ). In contrast, the other not only generates...
