Front Neurosci. 2016 Feb 29;10:45. doi: 10.3389/fnins.2016.00045. eCollection 2016.

Preclinical PET studies of β-amyloid (Aβ) accumulation are of growing importance, but comparisons between research sites require standardized and optimized methods for quantitation. Therefore, we aimed to evaluate systematically the (1) impact of an automated algorithm for spatial brain...

Controlling Positronium Annihilation with Electric Fields.

Physical review letters

Alonso AM, Cooper BS, Deller A, Hogan SD, Cassidy DB.
PMID: 26565466
Phys Rev Lett. 2015 Oct 30;115(18):183401. doi: 10.1103/PhysRevLett.115.183401. Epub 2015 Oct 27.

We show that the annihilation dynamics of excited positronium (Ps) atoms can be controlled using parallel electric and magnetic fields. To achieve this, Ps atoms were optically excited to n=2 sublevels in fields that were adjusted to control the...

Glia. 2015 Nov;63(11):2121-2132. doi: 10.1002/glia.22881. Epub 2015 Jun 23.

Satellite glial cell (SGCs) in trigeminal and dorsal root ganglia are altered structurally and functionally under pathological conditions associated with chronic pain. These changes include reactive gliosis, augmented coupling by gap junctions, and increased responses to ATP via purinergic...

Connecting the wakefield instabilities in dusty plasmas.

Melzer A.
PMID: 25493893
Phys Rev E Stat Nonlin Soft Matter Phys. 2014 Nov;90(5):053103. doi: 10.1103/PhysRevE.90.053103. Epub 2014 Nov 17.

The wakefield, or ion focus, formed by ions streaming past dust particles trapped in the plasma sheath leads to two types of instabilities: the Schweigert instability in multilayer systems and the mode-coupling instability that already appears in single-layer dust...
