Delayed Intracranial Hemorrhage after Endovascular Thrombectomy Is Associated With Poor Functional Outcomes and Elevated Systolic Blood Pressure

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Hemorrhagic transformation after endovascular thrombectomy can occur either immediately (early intracranial hemorrhage [ICH]) or on follow‐up imaging (delayed ICH), possibly reflecting distinct mechanisms and outcomes.

Deriving the mean excitation energy map from dual-energy and proton computed tomography

Physics and Imaging in Radiation Oncology, 2018
The mean excitation energy, I, is an essential quantity for proton treatment planning. This work investigated the feasibility of extracting the spatial distribution of I by combining two computed tomography (CT) modalities, dual-energy CT and proton CT ...

Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes

Advanced Functional Materials, EarlyView.
We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces
