Commodity futures are an important hedging tool in material trade, and by accurately predicting prices, countries and firms are able to make informed production and consumption decisions. This paper introduces a novel machine learning ensemble method that combines decomposition algorithms and physical optimization algorithms to predict commodity futures prices. First, the VMD(Variational mode decomposition) is optimized by the RIME algorithm (Rime optimization algorithm) to obtain the optimal modal decomposition results, and the trend and seasonal terms are predicted using the ELM (Extreme Learning Machines) and FA (Fourier Attention) models, respectively, and the results are finally synthesized.

View Article and Find Full Text PDFFlexible pressure sensors are the foundation of wearable/implantable biosensing and human-machine interfaces, and mainly comprise piezoresistive-, capacitive-, piezoelectric-, and triboelectric-type sensors. As each type of sensor exhibits different electro-mechanical behaviors, it is challenging to detect various physiological mechanical signals that cover a large pressure range using a given sensor configuration, or even a single type of sensor. Here, we report a capacitive-piezoresistive hybrid flexible pressure sensor based on face-to-face-mounted conductive micropillar arrays as a solution to this challenge.

Stretchable strain sensors have promising applications in health monitoring and human motion detection. However, only a few of the strain sensors reported to date have exhibited a multiscale strain range and a high gauge factor simultaneously. As such, most strain sensors cannot be used in applications that require both high sensitivity and a multiscale strain range.

Previous studies have shown that BMS-345541 (BMS, a specific IκB kinase β inhibitor) sensitized various tumor cells including MCF-7 breast cancer cells to ionizing radiation (IR). However, the mechanisms of BMS action are unknown. Since the expression of E1A-like inhibitor of differentiation 3 (EID3) was highly upregulated in MCF-7 cells after BMS treatment, we investigated the role of EID3 in the response of MCF-7 cells to IR.
