[Recognition of motor imagery electroencephalogram based on flicker noise spectroscopy and weighted filter bank common spatial pattern].

Due to the high complexity and subject variability of motor imagery electroencephalogram, its decoding is limited by the inadequate accuracy of traditional recognition models. To resolve this problem, a recognition model for motor imagery electroencephalogram based on flicker noise spectrum (FNS) and weighted filter bank common spatial pattern ( FBCSP) was proposed. First, the FNS method was used to analyze the motor imagery electroencephalogram.

Fungi and Archaea Control Soil NO Production Potential in Chinese Grasslands Rather Than Bacteria.

Nitrous oxide (NO) is a powerful greenhouse gas and the predominant stratospheric ozone-depleting substance. Soil is a major source of NO but remains largely uncertain due to the complicated processes of nitrification and denitrification performed by various groups of microbes such as bacteria, fungi, and archaea. We used incubation experiments to measure the total fungal, archaeal, and bacterial NO production potential and the microbial functional genes in soils along 3,000 km Chinese grassland transect, including meadow steppe, typical steppe, desert steppe, alpine meadow, and alpine steppe.
