Cerebellar Transcranial Direct Current Stimulation in People with Parkinson’s Disease: A Pilot Study

open access: yesBrain Sciences, 2020
People with Parkinson’s disease (PwPD) often experience gait and balance problems that substantially impact their quality of life. Pharmacological, surgical, and rehabilitative treatments have limited effectiveness and many PwPD continue to ...

Two-photon Double Ionization of H$_2$ in Intense Femtosecond Laser Pulses

open access: yes, 2010
Triple-differential cross sections for two-photon double ionization of molecular hydrogen are presented for a central photon energy of 30 eV. The calculations are based on a fully {\it ab initio}, nonperturbative, approach to the time-dependent ...

Perspective: Depression in Persons with Parkinson's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Depression is a prevalent and disabling syndrome characterized by sustained sadness and/or anhedonia, as well as cognitive and physical symptoms. In Parkinson's disease (PD), depression is both common and clinically challenging due to overlapping symptoms and complex etiologic interactions. Major depressive disorder occurs in approximately 17%

Imaging gas in a combustion engine with high‐energy X‐ray Compton scattering

open access: yesJournal of Synchrotron Radiation, EarlyView.
Compton‐scattering imaging has been applied to a combustion engine under operation for the first time. With a time‐resolved technique, a crank‐angle dependency of Compton‐scattered X‐ray intensity is obtained at different positions in a combustion chamber.We have developed a time‐resolved Compton‐scattering imaging technique for visualizing gas ...
