Status and trends of circumpolar peregrine falcon and gyrfalcon populations.

The peregrine falcon (Falco peregrinus) and the gyrfalcon (Falco rusticolus) are top avian predators of Arctic ecosystems. Although existing monitoring efforts are well established for both species, collaboration of activities among Arctic scientists actively involved in research of large falcons in the Nearctic and Palearctic has been poorly coordinated. Here we provide the first overview of Arctic falcon monitoring sites, present trends for long-term occupancy and productivity, and summarize information describing abundance, distribution, phenology, and health of the two species.

The total number of myelinated nerve fibers is reduced in corpus callosum in brains from patients with Alzheimer's disease.

The total number of myelinated fibers in corpus callosum (CC) in Alzheimer's disease is poorly described. Using a two-dimensional fractionator principle we estimated the total number of fibers in ten females patients with Alzheimer's disease (AD) (mean age 82.8 years) and 12 female control subjects (mean age 80.

A novel approach for discovering human behavior patterns using unsupervised methods.

Background: As is well known, elderly people gradually lose the ability of self-care. The decline can be reflected in changes in their daily life behavior. A solution to assess their health status is to design sensor-enhanced living environments to observe their behavior, in which unobtrusive sensors are usually used.

Multimodal activity monitoring for home rehabilitation of geriatric fracture patients--feasibility and acceptance of sensor systems in the GAL-NATARS study.

Background: Demographic change will lead to a diminishing care workforce faced with rising numbers of older persons in need of care, suggesting meaningful use of health-enabling technologies, and home monitoring in particular, to contribute to supporting both the carers and the persons in need.

Objectives: We present and discuss the GAL-NATARS study design along with first results regarding technical feasibility of long-term home monitoring and acceptance of different sensor modalities.

Methods: Fourteen geriatric participants with mobility-impairing fractures were recruited in three geriatric clinics.
