The ratio (RMR) is the standard measure of sex differentials in mortality. It is commonly known that the RMR was historically small and increased throughout the 20 th century. However, numerical properties might account for the trend in the RMR rather than sex differences in risk factors. In this study we examine the age pattern of the absolute difference in male to female mortality rates (DMR)...

Energetically costly behaviours, such as flight, push physiological systems to their limits requiring metabolic rates (MR) that are highly elevated above the resting MR (RMR). Both RMR and MR during exercise (e.g. flight or running) in birds and mammals scale allometrically, although there is little consensus about the underlying mechanisms or the scaling relationships themselves. Even less is ...

Resting metabolic rate (RMR) is a measure of the minimum energy requirements of an animal at rest, and can give an indication of the costs of somatic maintenance. We measured RMR of free-ranging European badgers (Meles meles) to determine whether differences were related to sex, age and season. Badgers were captured in live-traps and placed individually within a metabolic chamber maintained at ...

PURPOSE 1) To examine the effect of a 12-wk endurance exercise training program on RMR and 2) to provide insight into the mechanisms responsible for alterations in RMR that may occur after exercise training. METHODS Male participants (19-32 yr) in an exercise group (EX; n = 9) performed jogging and/or running 3-4 d x wk(-1), 25-40 min per session, at 60%-80% VO2max, whereas subjects in a cont...

OBJECTIVE To determine whether moderate cardiorespiratory fitness (CRF) or moderate to vigorous physical activity (MVPA) is associated with elevations in resting metabolic rate (RMR) similar to findings previously observed in endurance athletes. PARTICIPANTS AND METHODS Using a cross-sectional design, we measured CRF, RMR, body composition, energy expenditure, and time in MVPA via an arm-base...

Recent evidence suggests that neurons within the ventromedial medulla give rise to an inhibitory pathway(s) which projects directly upon the sympathetic preganglionic neuropil. The present investigations were initiated to determine the effects of interrupting this pathway on the expression of a learned autonomic response, defensively conditioned cardioacceleration in the pigeon. Experiment I in...

This paper presents network coding based reliable disjoint and braided multipath routing (NC-RMR ) for sensor networks, which forms multipath by hop-by-hop method and only maintains local path information of each node without establishing end-to-end paths. Neighbors of each local node are divided into groups according to their hops to sink nodes to improve the network load balancing. For furthe...
