A scheduling algorithm for maximum throughput based on the link condition in heterogeneous network

Nowadays, a lot of wireless interfaces can be used by mobile users to access the Internet, such as WLAN, WiMAX, WIFI and even 3G. If a mobile terminal is equipped with multiple interfaces, it can use them simultaneously to improve the performance at the hot point where different RANs (Radio Access Networks) overlap. This paper proposes a scheduling algorithm based on the link condition that ens...

Stress hormones: a link between maternal condition and sex-biased reproductive investment.

In species where offspring fitness is sex-specifically influenced by maternal reproductive condition, sex allocation theory predicts that poor-quality mothers should invest in the evolutionarily less expensive sex. Despite an accumulation of evidence that mothers can sex-specifically modulate investment in offspring in relation to maternal quality, few mechanisms have been proposed as to how th...

Suboptimal choice in a percentage-reinforcement procedure: effects of signal condition and terminal-link length.

Pigeons' choice between reliable (100%) and unreliable (50%) reinforcement was studied using a concurrent-chains procedure. Initial links were fixed-ratio 1 schedules, and terminal links were equal fixed-time schedules. The duration of the terminal links was varied across conditions. The terminal link on the reliable side always ended in food; the terminal link on the unreliable side ended with...

The Schwann Cell-Axon Link in Normal Condition or Neuro-Degenerative Diseases: An Immunocytochemical Approach

A condition dependent link between testosterone and disease resistance in the house finch.

Testosterone has recently been proposed as a link between male quality and health and the expression of sexual traits. We investigated the relationship between testosterone and measures of the individual condition and health of males in a natural population of house finches (Carpodacus mexicanus). We also conducted a captive experiment in order to test for the effects of testosterone on resista...
