The flux of noncommutative U(1) instanton through the fuzzy spheres
, 2006 From the ADHM construction on noncommutative $R_{\theta}^4$ we investigate different U(1) instanton solutions tied by isometry trasformations. These solutions present a form of vector fields in noncommutative $R_{\theta}^3$ vector space which makes ...

LRRK2 as a Potential Disease‐Modifying Target in Sporadic Parkinson's Disease
Movement Disorders, EarlyView.Abstract A growing understanding of the role that leucine‐rich repeat kinase 2 (LRRK2) plays in Parkinson's disease (PD) supports continued focus on this enzyme as a therapeutic target for PD. Accumulating evidence suggests that there are phenotypic, neuropathologic, and biological similarities between sporadic PD (sPD) and familial forms in which ...
