The effect of dance-based mind-motor activities on the quality of life in the patients recovering from COVID-19: A protocol for systematic review and meta-analysis.

Background: Since the outbreak of coronavirus disease 2019 (COVID-19), with the improvement of diagnosis and treatment level in various countries, more and more patients have been discharged after systematic treatment. In order to effectively promote the overall recovery of patients' physical and mental function and quality of life (QOL), the focus of clinical work should be gradually shifted to rehabilitation treatment. Dance-based mind-motor activities were defined as coordinated upright mind-motor movements that emphasize dynamic balance, structured through music or an inner rhythm (e.

Sparse estimation of backscattered echoes from underwater object using integrated dictionaries.

The problem of time-delays estimation of backscattered echoes from underwater targets is presented using a sparse reconstruction framework employing an integrated dictionary. To achieve high resolution, the used dictionary is usually defined over a finely spaced grid over the region of interest. Such a procedure may result in problems of being computational cumbersome or suffering from basis mismatch.

Rigid and elastic acoustic scattering signal separation for underwater target.

Underwater target elastic acoustic scattering and other acoustic scattering components are aliasing together in the time and frequency domains, and the existing signal processing methods cannot recognize the elastic scattering features under the aliasing condition because of the resolution limitation. To address this problem, this study, which is based on the target echo highlight model, analyzes the characteristics of target acoustic scattering components when the transmitted signal is a linear frequency modulation pulse. The target acoustic scattering structure in the fractional Fourier transform (FRFT) domain is deduced theoretically.

[Effect of nitrogen and phosphorus concentrations on the adsorption of BDE28 and BDE47 by Prorocentrum donghaiense dominant population].

The adsorption of 2,4, 4'-Tribromodiphenyl ether (BDE28) and 2,2', 4, 4'-Tetrabromodiphenyl ether (BDE47) by Prorocentrum donghaiense dominant population under different nitrogen and phosphorus concentrations was studied. Prorocentrum donghaiense dominant population consisted of Prorocentrum donghaiense and Skeletonema costatum, in which Prorocentrum donghaiense was dominant. Nitrogen was in form of nitrate and the concentrations tested were 0, 128 and 512 micromol x L(-1), and phosphorus was in form of phosphate and the concentrations tested were 0, 8 and 32 micromol x L(-1).

[Effects of Dipterocarpaceae on arbuscular mycorrhizal fungi].

An investigation was carried out on the colonization percentage, spore density, relative abundance, occurrence frequency, and species richness of arbuscular mycorrhizal (AM) fungi on 4 species of Dipterocarpaceae trees grown both in natural forests in Yunnan and Hainan Provinces and in greenhouse pots. The results showed that all dipterocarp species were able to form AM, the colonization rates ranged from 30.6% to 45.
