BACKGROUND Depressive symptoms and physical performance are inversely associated, but it is unclear whether their association is bidirectional. We examined whether the association between depressive symptoms and physical performance measured using gait speed is bidirectional. METHODS We used a national sample of 4,581 community-dwelling people aged 60 years and older from the English Longitud...

There is an inherent coupling relationship between the time when buses arrive at station and they intersection, it essential to study as a whole maximize benefits of company operations passenger services. In this study, coordinated control method signal priority speed regulation in stop-skipping mode peak hours proposed. First, decision result obtained based on historical flow data. On basis, s...

Empirical data shows that current account has the property of mean-reversion and the speed of current account convergence is heterogenous across countries. In order to explore the factors which affect the current account adjustment speed of a small country, this paper builds up a model to study how current account would be affected by factors such as labor supply and monetary policies. We found...

T he present paper investigates the impact of the financial crisis on the interaction between the lending rates, deposit rates and money market rates through the process of retail bank interest rate pass-through in the countries of the Euro area. Among our findings is the heterogeneity of bank rate adjustments across sectors, loans and deposits. That was mainly marked during the pre-...

Background: According to the results of epidemiological studies, human beings from various races, colors, cultural, educational and economic backgrounds are affected by cancer worldwide, thereby encouraging researchers to conduct extensive studies in this regard. We aimed to compare the components of quality of life and adjustment in both cancer-stricken and healthy children. Materials and Meth...

According to the requirements of a wide speed range, variable-geometry supersonic inlet with inner surface adjustment is studied. The basic design model established, and influence profile on resisting back pressure ability performance boundary are analyzed using theoretical method. Based numerical simulation method, flow field carried out, parameter distribution studied in comparison fixed-geom...

Lateral control of an autonomous guided vehicle is influenced strongly by both the longitudinal speed and the position input command (magnitude of the reference signal) of the vehicle. For that reason some suitable strategies for governing the vehicle are adaptive and robust controllers. In this article, an adaptive scheme which combines a model reference approach with a fractional order adjust...
