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.

Allocative efficiency and the productivity slowdown

Canadian Journal of Economics/Revue canadienne d'économique, EarlyView.

We extend the framework of Oberfield (2013) to derive sufficient statistics for allocative efficiency and decompose aggregate productivity growth in a multisector economy.

IgG4 positivity on circulating T cells after PD‐1 therapy may indicate residual antibody binding rather than sustained functional PD‐1 blockade. During sequential ramucirumab plus docetaxel plus G‐CSF treatment, peripheral IgG4+ T‐cell dynamics may also be influenced by redistribution and treatment‐related confounders, limiting direct inference about ...
