Control of dual-channel optical bistability in a carbon nanotube nanoresonator coupled with a metallic nanoshell.

We theoretically present a flexible method to obtain dual-channel optical bistability (OB) in a coupled system consisting of a metallic nanoshell (MNS) and a carbon nanotube (CNT) nanomechanical resonator (NR) beyond the dipole approximation. The MNS is made of a metallic core and a dielectric shell. The results show that, the four-wave mixing signal is suppressed significantly due to multipole polarizations in comparison to that in the dipole approximation.

Objective: This study aims to explore trends in sedentary behavior among Chinese children aged 6-17 years per demographic and social characteristics.

Methods: A total of 4,341 children aged 6-17 years who participated in the from 2004 to 2015 were included. Repeated measures from mixed-effects models were applied to test trends in sedentary behaviors, which were further analyzed after applying stratification according to gender, age, urbanization level, residential area, and region.

Physical Activity and Sedentary Behaviors among Chinese Children: Recent Trends and Correlates.

Objective: This study was aimed at examining the trends and correlates of physical activity (PA) and sedentary behaviors among Chinese children.

Methods: A total of 4,341 subjects (6,936 observations) aged 6-17 years who participated in the China Health and Nutrition Survey (2004-2015) were included. Of the subjects, 41% participated in the survey twice or more.

Recent Trends in Physical Activity among Chinese Children Based on Their Demographic and Social Characteristics.

Aimed to explore the trends in physical activity among Chinese children, data of 4,341 children aged 6-17 years who participated in at least one round of "China Health and Nutrition Survey" from 2004 to 2015 were analyzed. Repeated measures mixed models were applied to test the trends in physical activity, which were further analyzed after applying stratification on gender, age, urbanization level, residential area and region. The volume of total physical activity in Chinese children aged 6-17 years showed a downward trend from 2004 to 2015, especially among children residing in medium and high urbanization communities, the south and urban areas of China, so that more efforts need to be put to promote their physical activity.

Mechanism of Placenta Damage in Gestational Diabetes Mellitus by Investigating TXNIP of Patient Samples and Gene Functional Research in Cell Line.

Introduction: Gestational diabetes mellitus (GDM) is a gestational complication that affects maternal and child health. The placenta provides the fetus with the necessary nutrition and oxygen and takes away the metabolic waste. Patients with GDM are diagnosed and treated merely on the basis of the blood glucose level; this approach does nothing to help evaluate the status of the placenta, which is worth noting in GDM.
