Multiplexed intravascular molecular imaging using dual-channel near-infrared fluorescence integrated with optical coherence tomography

Abstract Accurate characterization of high-risk atherosclerotic plaques requires both structural and molecular information. While integrated optical coherence tomography (OCT)/near-infrared fluorescence (NIRF) imaging enables simultaneous assessment of plaque morphology and biolo...

Sequential Dual Nanoparticle Approach for Extracellular Matrix Remodeling and Targeted Chemotherapy through Liposome–Exosome Hybridization in Pancreatic Cancer

Pancreatic cancer remains one of the most aggressive and treatment-resistant malignancies, with a poor prognosis and limited response to conventional therapies. Although liposomal doxorubicin (DOX) formulations reduce systemic toxicity, their clinical use is constrained by insuff...

Nonlinear Electro‐Optic Visible Photonic Circuits for Solid‐State Quantum Defects

Integrated visible photonic engines for solid-state quantum defects provide a foundation for scalable quantum networks. While miniaturization is advancing, active manipulation remains limited by the difficulty of achieving simultaneous milliwatt-scale visible light generation and...

Beyond Partnership Quantity: A Meso-Level Framework for Effective External Cooperation in International Development Organisations

International development organisations have never maintained more formal cooperation agreements, yet the relationship between partnership quantity and development outcomes remains empirically inconclusive. This article argues that explaining this gap requires shifting the unit o...

Viscous scaling laws for wall shear stress in asymmetric twin-jet impingement

Asymmetric twin impinging jets are widely utilized in various engineering fields, but the fundamental physics of nonlinear ground loads under momentum imbalance remains unclear. In this study, steady-state computational fluid dynamics simulations are performed to construct an ext...

Visual trust signals in digital financial marketplaces: eye-tracking evidence from verification badges

Purpose This study examines when a platform-issued verification badge affects consumer choice in a high-uncertainty digital financial marketplace. Integrating signaling theory and attention-based choice research, it distinguishes signal assignment, item-card visual consideration,...

Recent change in northward migration of the East Asian summer front and increased compound wet–hot conditions

The East Asian summer front (EASF) plays a key role in regional precipitation and heat stress, yet its long-term positional changes remain poorly understood. Using a front-tracking algorithm applied to ERA5 reanalysis (1979–2025), we identify northward migration of the EASF durin...
