Upper Cervical Cord Area as a Biomarker of Conversion to Secondary Progressive Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective This study assessed whether upper cervical cord area (UCCA) measured on routine brain MRI can serve as a biomarker of conversion to SPMS. Methods This is a single‐center retrospective cohort study of RRMS patients with cross‐sectional and longitudinal analyses of clinical and MRI data. Future SPMS converters were matched by age, sex,

Majority decoded automatic repeat request error control schemes [PDF]

open access: yes, 1988
The authors propose a simple method to improve the performance of automatic repeat request (ARQ) error control. To minimize the hardware and software overhead they do not use a sophisticated coding method.
