Article Synopsis
- This paper discusses the design of a Class-AB power amplifier specifically for correcting nonlinearity in pressure-mode sensor applications, utilizing advanced circuit techniques to boost gain and maintain stability.
- The amplifier employs a unique structure combining gain-boosting folded cascode, push-pull configuration, and adaptive output, resulting in a high-efficiency system that can handle resistive sensors ranging widely in resistance values.
- Final simulations reveal the amplifier achieves over 140 dB gain and effectively reduces sensor nonlinearity to just 4% of its initial value, with minimal output voltage error despite varying environmental conditions.
Article Synopsis
- Scientists studied how trees in a forest, especially balsam firs, grow and make wood during the year.
- They found that different trees grow at different speeds and times, and those that grew more cells had longer growing seasons.
- However, even with longer growing seasons due to climate change, it doesn't mean that these trees will capture more carbon from the atmosphere.
Processing is a traditional pharmacy technology based on traditional Chinese medicine theory. The traditional Chinese medicine (TCM) ingredients should be processed before being used as a medicine. Processed bitter almonds are widely used in the clinic in TCM for the treatment of cough and asthma.

In the study, the regression models were established using multivariate regression methods with the results from conventional chemical analytical methods as reference values. The multivariate regression methods, partial least squares regression (PLSR) and principal component regression (PCR), were discussed and the PLSR was more suitable.

Fourier transform infrared (FTIR) microspectroscopy technology is the combination of the FTIR spectrometer and the microscope. This technology is of simple preparation of the samples, can be used in micro-area analysis and micro-samples, and reflect the nature of the samples spectra. Panax ginseng include mountain cultivated ginseng (MCG), garden cultivated ginseng (GCG) and mountain wild ginseng (MWG), but the excavation of MWG is prohibited in China.
