The Earliest Feathers from the Lower Cretaceous Dabeigou Formation of North Hebei: Implications for the Early Evolution of the Jehol Biota

Integrative Zoology, EarlyView.
This study reports two isolated feather fossils from the Lower Cretaceous Dabeigou Formation in northeastern China. Morphological analyses identified them as the earliest known feathered theropods (potentially including avian) in the Jehol Biota. This finding reveals a complex ecosystem at the dawn of the Jehol Biota, bridging the temporal and faunal ...

Contrast‐Induced Encephalopathy Following Elective Endovascular Aneurysm Treatment: The Role of Dual‐Energy CT and Correlation With Delphi Diagnostic Criteria

Journal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT Introduction Contrast‐induced encephalopathy (CIE) is an increasingly recognised neurological complication of iodinated contrast administration during neurointerventional procedures. Recently published 2025 Delphi‐based diagnostic criteria and management algorithms aim to standardise clinical practice; however, optimal neuroimaging strategies ...

Calibrating artificial intelligence against human expertise using femoral nerve segmentation on ultrasound: a consensus framework

Anaesthesia, EarlyView.
Summary Introduction Meaningful validation of artificial intelligence for medical image interpretation requires comparison against human expert performance, yet multi‐rater frameworks establishing such comparisons remain uncommon. Methods We developed and applied a consensus framework using nine clinicians who independently segmented the femoral nerve ...

En face localization of retinal telangiectatic capillaries using OCT compared with ICG angiography in chronic vascular macular oedema

Acta Ophthalmologica, EarlyView.
Abstract Purpose Retinal telangiectatic capillaries (TelCaps) are microvascular abnormalities associated with chronic vascular macular oedema and suboptimal response to intravitreal therapy. Targeted laser photocoagulation is beneficial but requires precise localization using indocyanine green angiography (ICG‐A), the reference standard. However, ICG‐A

Reciprocal Tariffs and Systemic Trade Losses: Evidence From Korea, Japan, and the EU

Asia Pacific Viewpoint, EarlyView.
ABSTRACT The resurgence of U.S. protectionism, the proposal of universal reciprocal tariffs targeting major trading partners, poses systemic risks to global trade that existing bilateral analyses have not fully captured. This paper examines the economic consequences of U.S.
