BACKGROUND Aging is associated with increases in fat mass (FM) and decreases in fat-free mass (FFM) that may affect physical capacity. However, it is not clear whether high FM or low FFM contribute more to a reduction in physical capacity. METHODS A structural equation modeling strategy was used to test an explanatory model of the association between body composition and physical capacity. Th...

Community-based interventions to promote physical activity (PA) among older adults are of high interest in health promotion since they promise to be effective strategies to reach this population group. Community capacity building, that is, the local promotion of knowledge, skills, commitment, structures, and leadership, is among the recommended core strategies. However, little guidance is provi...

As technology trends continue to reduce the size, power consumption and cost of embedded networked sensors, they are rapidly approaching the small size and low cost necessary to allow a much wider range of novel usage. The resulting tremendous growth in sensor networks applications predicates increases in both scale and density for their wireless networks. Our initial measurements of an active ...

This paper presents a investigation on the performance of security under κ-μ shadowed fading channels using the Wyner’s classic wiretap model. A better fit was presented for the κ-μ shadowed fading channel curves in relation to other fading models, as Rayleigh and Nakagami-m. Results and analyses are obtained through the Secrecy Outage Probability, the Strictly Positive Secrecy Capacity and Ave...

In quantum information theory, a basic question often presented is how efficiently can one transmit classical information over a quantum channel.[1, 2, 3] Because of the non-orthogonality of quantum states, the channel capacity is different from that of the classical channel discussed in [4, 5] . Recently, this question has attracted new attention due to the rapid progress in quantum informatio...

This article outlines a theoretical framework for an interactive, research-driven approach to building policy capacities in health promotion. First, it illustrates how two important issues in the recent public health debate, capacity building and linking scientific knowledge to policy action, are connected to each other theoretically. It then introduces an international study on an interactive ...

We study the non-asymptotic fundamental limits for transmitting classical information over memoryless quantum channels, i.e. we investigate the amount of classical information that can be transmitted when the channel is used a finite number of times and a constant average error is permissible. We show that, in the absence of entanglement between different channel uses, the non-asymptotic fundam...

We discuss the BCI based on inner tones and inner music. We had some success in the detection of inner tones, the imagined tones which are not sung aloud. Rather easily imagined and controlled, they offer a set of states usable for BCI, with high information capacity and high transfer rates. Imagination of sounds or musical tunes could provide a multicommand language for BCI, as if using the na...
