Regret Aversion and Market Provision of (Cyber)Security

This paper studies the effect of market structure on cybersecurity under alternative behavioral models of consumer risk preference. I show that consumer regret aversion can reverse the competitive effect on security provision. If consumers are expected utility maximizers, competi...

Molecular Machine‐Driven Fluorogenic Probes for Motion–Signal Conversion and Hydrophilicity Retention in Live‐Cell Nanoscopy

ABSTRACT Traditional fluorogenic and cell‐permeable molecular probes for live‐cell nanoscopy mainly rely on structural or hydrophilicity changes to generate intracellular fluorescence signals. Here, we introduce molecular machines into fluorogenic probe design. As a proof of conc...

Sintilimab plus Bevacizumab biosimilar IBI305 and chemotherapy as a first-line treatment in advanced gastric or gastroesophageal junction adenocarcinoma (SBAGA): a single-arm, phase Ib/II study

Adding anti-PD-1 or anti-VEGF therapy to chemotherapy improves survival in patients with advanced gastric cancer, yet outcomes remain poor. This Phase Ib/II trial aimed to evaluate the efficacy and safety of combining sintilimab, the bevacizumab biosimilar IBI305, and CapeOX chem...
