Imidacloprid is a systemic insecticide effective in controlling the exotic pest (hemlock woolly adelgid) in eastern hemlock () trees. Concerns over imidacloprid impacts on nontarget species have limited its application in southern Appalachian ecosystems. We quantified the movement and adsorption of imidacloprid in forest soils after soil injection in two sites at Coweeta Hydrologic Laboratory ...

The aim of this study was to test the effect that changing targets during a simple long lunge attack in fencing exerts on the temporal parameters of the reaction response, the execution speed, and the precision and the coordination of the movement pattern. Thirty fencers with more than 10 years of experience participated in this study. Two force platforms were used to record the horizontal comp...

Comparisons of proteins show that they evolve through the movement of domains. However, in many cases, the underlying mechanisms remain unclear. Here, we observed the movements of DNA recognition domains between non-orthologous proteins within a prokaryote genome. Restriction-modification (RM) systems, consisting of a sequence-specific DNA methyltransferase and a restriction enzyme, contribute ...

Many single-neuron recording studies have examined the degree to which the activity of primary motor cortex (M1) neurons is related to the kinematics and kinetics of various motor tasks. This has not been explored as extensively for arm movement-related neurons in posterior parietal cortex area 5. We recorded the activity of 78 proximal-arm-related neurons in area 5 of two monkeys while they us...

Although the extraocular muscles contain stretch receptors it is generally believed that their afferents exert no influence on the control of eye movement. However, we have shown previously that these afferent signals reach various brainstem centres concerned with eye movement, notably the vestibular nuclei, and that the decerebrate pigeon is a favourable preparation in which to study their eff...

In the event of a fire in nursing homes and hospitals, those unable to move by themselves should seek help an assistant. However, there are not enough staff evacuate everyone at hospital, making it difficult depend on assistants everyone. Therefore, autonomous movement that does require assistant can be very effective means evacuation such cases. this study, evaluation accuracy, required time, ...
