Journal ArticleDOI
The Vienna LTE simulators - Enabling reproducibility in wireless communications research
Christian Mehlfuhrer,Josep Colom Ikuno,Michal Simko,Stefan Schwarz,Martin Wrulich,Markus Rupp +5 more
TL;DR: This study explains how link and system level simulations are connected and shows how the link level simulator serves as a reference to design the system level simulator, and compares the accuracy of the PHY modeling at system level by means of simulations performed both with bit-accurate link level simulations and PHY-model-based systemlevel simulations.
Journal ArticleDOI
Filter Bank Multicarrier Modulation Schemes for Future Mobile Communications
TL;DR: This paper provides a unifying framework, discussion, and performance evaluation of FBMC and compares it with OFDM-based schemes and derives closed-form solutions for the signal-to-interference ratio in doubly-selective channels and shows that in many practical cases, one-tap equalizers are sufficient.
Journal ArticleDOI
The 'swallow tail' appearance of the healthy nigrosome - a new accurate test of Parkinson's disease: a case-control and retrospective cross-sectional MRI study at 3T
TL;DR: Assessing the substantia nigra on SWI for the typical ‘swallow tail’ appearance has potential to become a new and easy applicable 3T MRI diagnostic tool for nigral degeneration in Parkinson's disease.
Journal ArticleDOI
Visualization of nigrosome 1 and its loss in PD Pathoanatomical correlation and in vivo 7 T MRI
Anna I. Blazejewska,Stefan Schwarz,Alain Pitiot,Mary C. Stephenson,James Lowe,Nin Bajaj,Richard Bowtell,Dorothee P. Auer,Penny A. Gowland +8 more
TL;DR: In vivo and PM MRI with histologic correlation demonstrates that high-resolution 7 T MRI can directly visualize nigrosome 1, which might prove useful in developing a neuroimaging diagnostic test for Parkinson disease.
Journal ArticleDOI
High resolution magnetic susceptibility mapping of the substantia nigra in Parkinson's disease.
Ashley K. Lotfipour,Samuel Wharton,Stefan Schwarz,Vamsi Gontu,Andreas Schäfer,Andrew Peters,Richard Bowtell,Dorothee P. Auer,Penny A. Gowland,Nin Bajaj +9 more
TL;DR: This study presents the first quantitative, in vivo measurements of the susceptibility of the substantia nigra in patients with Parkinson's disease.
