Using information theory to determine optimum pixel size and shape for ecological studies: Aggregating land surface characteristics in arctic ecosystems (2009)

Stoy, P. C., Williams, M., Spadavecchia, L., Bell, R.A., Prieto-Blanco, A., Evans, J.G., ...

Quantifying vegetation structure and function is critical for modeling ecological processes, and an emerging challenge is to apply models at multiple spatial scales. Land surface heterogeneity is...

Upscaling leaf area index in an Arctic landscape through multiscale observations (2008)

Williams, M., Bell, R., Spadavecchia, L., Street, L.E.

Monitoring and understanding global change requires a detailed focus on upscaling, the process for extrapolating from the site-specific scale to the smallest scale resolved in regional or global...

Topographic controls on the leaf area index and plant functional type of a tundra ecosystem (2008)

Spadavecchia, L., Williams, M., Bell, R., Stoy, P. C., Huntley, B.

Leaf area index (LAI) is an emergent property of vascular plants closely linked to primary production and surface energy balance. LAI can vary by an order of magnitude among Arctic tundra communities...

Response of arm flexor muscles to magnetic and electrical brain stimulation during shortening and lengthening tasks in man.

Abbruzzese, G, Morena, M, Spadavecchia, L, Schieppati, M

1. The responses of the brachioradialis and biceps brachii muscles to non-invasive magnetic and electrical stimulation of the human motor cortex have been investigated during performance of different...

VEP changes in Parkinson's disease are stimulus dependent.

Tartaglione, A, Pizio, N, Bino, G, Spadavecchia, L, Favale, E

Two stimulus configurations (gratings and checkerboards) have been presented to a series of consecutive patients with the aim of exploring VEP changes in Parkinson's disease. The outcome turned out...

Electrical stimulation of the motor tracts in cervical spondylosis.

Abbruzzese, G, Dall'Agata, D, Morena, M, Simonetti, S, Spadavecchia, L, Severi, P, ...

Motor action potentials evoked by percutaneous electrical stimulation of the scalp and of the cervical (or lumbar) vertebral region were recorded from the biceps, thenar and tibialis anterior muscles...
