In real world industrial applications, the working environment of a bearing varies with time, and some unexpected vibration noises from other equipment are inevitable. In order to improve the anti-noise performance of neural networks, a new prediction model and a multi-channel sample generation method are proposed to address the above problem. First, we proposed a multi-channel sample representation method based on the envelope time-frequency spectrum of a different channel and subsequent three-dimensional filtering to extract the fault features of samples.

In agroecosystem, arbuscular mycorrhizal fungi have mutually beneficial symbiosis with roots of many crops. Meanwhile, this special fungal community is also affected by agricultural mana-gements such as fertilization. The objective of this study was to investigate the effects of long-term fertilization managements (no fertilizer, chemical fertilizer, chemical fertilizer combined with straw, chemical fertilizer combined with manure) on arbuscular mycorrhizal fungal community (AM fungal community) in lime concretion black soil, and to identify the indicator species in each fertilization regime.

Methods: The analysis was carried out on a Ultimate AQ C18 (250 mm x 4.6 mm, 5 μm) column with the gradient elution of acetonitrile and KH2PO4 buffer soution, whose pH was adjusted to 3.
Objective: To study the material composition of Tibetan medicine "Brag-zhun", and to provide the basis for interpretation of its source and reference for the establishment of quality standards.
Methods: Pharmacognosy routine method was used in macroscopic and microscopic identifications, inductively coupled plasma spectrometry was carried out to determine 26 kinds of mineral elements,and X-ray diffraction analysis was used for the crystalline phase detection of Brag-zhun. The content of calcium,organic matter, humic acid and fulvic acid was determined according to GB/T 14610-2008, "technical specification for soil analysis" , GB/T 11957-2001 and capacity titration, respectively.
A simple, specific, and sensitive ultra high performance liquid chromatography with tandem mass spectrometry method was developed and validated for the simultaneous quantification of nine compounds including a new compound, rhamnazin-3-Ο-β-D-(6″-β-hydroxy-β-methyglutaryl)-β-D-glucoside-4'-Ο-β-D-glucoside, in rat plasma using baicalin as an internal standard. The plasma samples were pretreated and extracted by protein precipitation with 0.2% formic acid in acetonitrile.
