BACKGROUND This study investigated the association of travel mode to school and non-school destinations with objectively assessed health markers and physical activity in an ethnically diverse sample of inner-city UK schoolchildren. METHODS We used data from the Camden Active Spaces project (n = 450 children aged 9.1 yrs) to examine associations of school travel mode and frequency of active tr...

Energy shortage and atmospheric pollution problems are getting more serious in China, and transportation is the main source of energy consumption, pollutants, and carbon emissions. This study combined the activity-based analysis method with emission models, and investigated the influence mechanism of people’s activity travel scheduling on transportation energy consumption and emissions on holid...

Over the past couple of decades, Global positioning system (GPS) technology has been utilized to collect large-scale data from travel surveys. As the precise spatiotemporal characteristics of travel could be provided by GPS devices, the issues of traditional travel survey, such as misreporting and non-response, could be addressed. Considering the defects of dedicated GPS devices (e.g., need muc...

Introduction: Travel health practice and research in Egypt lag behind both needs and demands. This study was done in two parts to assess travel health knowledge, attitude, and practice (KAP) among Egyptian travelers. Methods: This survey was conducted at the departure halls of Cairo International Airport and included 1500 travelers to Africa (excluding No...

From the perspective of nonlinear science, it is argued that one may accept physicalism and reject substance dualism without being forced into reductionism. This permits a property dualism under which biological and mental phenomena may emerge from intricate positive feedback networks, involving many levels of both the biological and cognitive hierarchies.

Synchronization of chaotic and Lu system has been done using the active sliding mode control strategy. Regarding the synchronization task as a control problem, fractional order mathematics is used to express the system and active sliding mode for synchronization. It has been shown that, not only the performance of the proposed method is satisfying with an acceptable level of control signal, but...
