The information technology (IT) and IT products industry has become the essential " first pillar " industry and an important force behind the growth of China's national economy. However, information technology-related electrical and electronic waste has also caused a considerable environmental burden to China. This paper focuses on the developing circular(More)
OBJECTIVE Sarcopenia might be associated with bone fragility in elderly individuals. This study aimed to investigate the prevalence of sarcopenia and its association with fragility fracture sites in elderly Chinese patients. METHODS Patients (322 men and 435 women) aged 65-94 years and with a history of fragility fractures in the ankle, wrist, vertebrae(More)
VO2 (M) STF through reduction of V2O5 STF was prepared. The results illustrate that V2O5 STF can be successfully obtained by oblique angle thermal evaporation technique. After annealing at 550 °C/3 min, the V2O5 STF deposited at 85° can be easily transformed into VO2 STF with slanted columnar structure and superior thermochromic properties. After deposition(More)
In this paper, we consider multi-component generalizations of the Hirota–Satsuma coupled Korteweg–de Vries (KdV) equation. By introducing a Lax pair, we present a matrix generalization of the Hirota–Satsuma coupled KdV equation, which is shown to be reduced to a vector Hirota–Satsuma coupled KdV equation. By using Hirota's bilinear method, we find a few(More)
