Cerebral Amyloid Angiopathy Is Associated With Higher R2 Relaxation Rate: An MRI and Pathology Study
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Cerebral amyloid angiopathy (CAA) involves β‐amyloid deposition in the walls of cortical and leptomeningeal small vessels. Transverse relaxation rate (R2) is a major source of contrast in MRI. This study tested the hypothesis that CAA is associated with R2, extracted the spatial pattern of CAA‐related R2 abnormalities, and evaluated ...

On the importance of the nonequilibrium ionization of Si IV and O IV and the line-of-sight in solar surges [PDF]
, 2018 Surges are ubiquitous cool ejections in the solar atmosphere that often appear associated with transient phenomena like UV bursts or coronal jets. Recent observations from the Interface Region Imaging Spectrograph (IRIS) show that surges, although traditionally related to chromospheric lines, can exhibit enhanced emission in Si IV with brighter ...

Arthritis Care &Research, EarlyView.Objective Patients with knee osteoarthritis rely on symptomatic treatments, in which up to 75% of the pain reduction can be attributed to the placebo effect. This effect may vary based on treatment type (eg, biologics vs nonbiologic injection) and route of administration (eg, intra‐articular vs topical vs oral).

International Journal of Adaptive Control and Signal Processing, EarlyView.Summary Data‐driven forecasting of ship motions in waves is investigated through feedforward and recurrent neural networks as well as dynamic mode decomposition. The goal is to predict future ship motion variables based on past data collected on the field, using equation‐free approaches.
