Strong Interference Elimination in Seismic Data Using Multivariate Variational Mode Extraction.

Seismic data acquired in the presence of mechanical vibrations or power facilities may be contaminated by strong interferences, significantly decreasing the data signal-to-noise ratio (S/N). Conventional methods, such as the notch filter and time-frequency transform method, are usually inadequate for suppressing non-stationary interference noises, and may distort effective signals if overprocessing. In this study, we propose a method for eliminating mechanical vibration interferences in seismic data.

Individualized Implementation of Youth Quality of Life Instrument-Research Version (YQOL-R) Among Chinese Adolescents with Different Weight Status.

Purpose: This study implemented the individualized Youth Quality of Life Instrument-Research Version (YQOL-R) to estimate the quality of life (QoL) among Chinese adolescents with three different Body Mass Index (BMI) levels. The study aims to explore and provide a reference for developing individualized QoL (IQoL) measurements in China.

Methods: The sample consisted of 822 aged 11-18 from nine schools.

A novel prescription pedometer-assisted walking intervention and weight management for Chinese occupational population.

Background And Aim: Information technology has been previously used for the research and practice of health promotion. Appropriate and effective health promotion methods used by professional groups remain to be investigated. This study aimed to assess the feasibility and effectiveness of a weight management program among the Chinese occupational population using and a novel information technology exercise prescription.

Factors influencing quality of life of obese students in Hangzhou, China.

Objective: To evaluate the quality of life (QOL) of overweight and obese middle or high school students and identify relevant factors influencing their QOL scores.

Methods: 716 students were recruited from 6 middle or high schools in Hangzhou, China. The Chinese version of the Youth Quality of Life Instrument-Weight Module (YQOL-W) was self administered.

Measurement properties of the Chinese version of the Youth Quality of Life Instrument-Weight Module (YQOL-W).

Background: Childhood obesity is a growing public health concern in China. It not only compromises physical health, but also has negative impacts on psychosocial well-being. As obesity rates increase, finding out what the perceptions of Chinese youth are regarding their weight is important for intervention planning and evaluation.
