Saproxylic insect communities inhabiting tree hollow microhabitats correspond with large food webs which simultaneously are constituted by multiple types of plant-animal and animal-animal interactions, according to the use of trophic resources (wood- and insect-dependent sub-networks), or to trophic habits or interaction types (xylophagous, saprophagous, xylomycetophagous, predators and commens...

BACKGROUND Among youth, participation in extracurricular physical activities at school and organised physical activities in the community is associated with higher physical activity levels. The objective was to determine if participation in organised physical activities during early adolescence protects against declines in physical activity levels during adolescence. METHODS Every 3 months fo...

The growing availability of network infrastructure is paralleled by the ever growing number of network applications. These applications rely on network services to answer business needs and enable the interaction of users and devices. Not surprisingly, the development of applications promotes further research in the field of network systems. In particular, the growing complexity of network infr...

After a brief overview of optical resonant filter technology, and three-dimensional waveguide technology, which are key candidates for optical memory, this report discusses potential applications in detail, with a clear indication of the trade-offs involved. We assume that in order to find practical applications, optical memory must be organised into delay-lines. Otherwise, for example, if opti...
