Evaluating Immunotherapy Outcomes in Elderly Patients with Extensive-Stage Small-Cell Lung Cancer (KCSG LU23-15)

PurposeChemoimmunotherapy has improved outcomes in extensive-stage small-cell lung cancer (ES-SCLC), but its benefit in older adults remains uncertain because this population is underrepresented in clinical trials.We evaluated the real-world efficacy of first-line atezolizumab pl...

An open-source FPGA control architecture for solid-state spin-photon interfaces

Scalable quantum networks require quantum interfaces that coherently connect stationary matter qubits with flying photonic qubits. In solid-state defect platforms, such interfaces require coordinated optical excitation, microwave spin control, photon detection, and feedback with...

Dopant-MediatedStokes Shifting in Perovskite QuantumDots for Enhanced UV-Stable Organic Photodetection

Abstract Ultraviolet (UV) photodetection is critical for applications spanning environmental monitoring to optical communication; however, the high photon energy of UV light introduces inherent trade-offs between sensitivity and operational stability. In particular, organic photo...

International Students’ Academic Adjustment in South Korea: A Qualitative Case Study

Although research on international students’ academic experiences in South Korean universities has steadily grown, relatively little attention has been paid to how undergraduate international students from diverse national backgrounds experience and navigate academic adjustment i...

Corporate Social Responsibility, Rural Development, and Demographic Sustainability in a Transition Economy

Retaining population is a core condition for the long-term sustainability of rural communities, yet rural out-migration is often treated merely as evidence of local development failure. Agriculturally productive regions may continue to lose population even when output, corporate...

Creating Psychological Ownership Through Augmented Reality

ABSTRACT Augmented reality (AR) technologies are a disruptive innovation that is reshaping innovation strategies in luxury retail. This study developed a framework to explain how the attributes of AR technologies, namely AR quality, haptic imagery and customisation, shape consume...

Liter-Scale PrecisionSynthesis and Measurement ofNano-to-Micrometer Scale PSNPs with Graphene Liquid Cells

Abstract Monodisperse polystyrene nanoparticles (PSNPs) have great potential as standard materials in various fields, including environmental analysis, biological research, and instrumental calibration. However, reproducible liter-scale synthesis of PSNPs with controlled sizes ac...

Prospective Head‐To‐Head Comparison of a 10‐Color Single‐Tube Flow Cytometry and EuroFlow Next‐Generation Flow in Multiple Myeloma Minimal Residual Disease

BACKGROUND: Minimal residual disease (MRD) assessment by next-generation flow cytometry (NGF) is an important prognostic tool in multiple myeloma (MM). Although the EuroFlow NGF assay provides highly standardized and sensitive MRD detection, its dual-tube workflow requires larger...

Architectural Control of Bottlebrush Polymers for Tuning Rheology of Polylactic Acid Blends

Abstract A series of polylactic acid (PLA)-based bottlebrush polymers (BBPs) with controlled grafting ratios were synthesized and blended with linear PLA to examine the role of bottlebrush architecture in governing melt rheology. The blends exhibited a nonmonotonic dependence of...

Harnessing Li‐Ion Binding Energy for Solvation‐Guided Electrolyte Additive Design and Robust Solid Electrolyte Interphase Reinforcement

The rational design of electrolyte systems is essential for stabilizing the electrode-electrolyte interface to enhance the electrochemical performance of lithium-ion batteries (LIBs). Although conventional strategies focus on the introduction of specific functional moieties, the...

Clinical Characteristics and Outcomes of Pediatric Patients With Long QT Syndrome: A Korean Multicenter Cohort Study

This multicenter nationwide cohort study comprehensively analyzed the clinical features, genetic architecture, and outcomes of Korean pediatric patients with long QT syndrome (LQTS).Prolonged QT intervals, fetal arrhythmia, and LQT2/3 genotypes compared to LQT1 were independent r...

Unipolar Barrier Near‐Infrared 2D Photodetectors for 3D Image Sensors

ABSTRACT Photodetectors sensitive to the near‐infrared (NIR) range are of great importance for applications in machine vision, autonomous driving, and three‐dimensional (3D) imaging under low‐light or adverse weather conditions. Recently, two‐dimensional (2D) semiconductors have...

Early On-Treatment Host Fitness Dynamics Refine Prognostic Stratification in Advanced NSCLC Receiving First-Line Immunotherapy

PurposeWe assessed whether baseline and early on-treatment measurements of host fitness using the Prognostic Nutritional Index (PNI) provide complementary prognostic information in advanced non-small cell lung cancer (NSCLC). Materials and MethodsWithin the prospective, multicent...

Gold‐Stabilized Copper Enables Anodic Hydrogen Evolution for Ultralow‐Voltage CO‐to‐Ethylene Electrolysis

ABSTRACT Electrochemical upgrading from CO 2 and CO to ethylene has typically been coupled with the oxygen evolution reaction (OER), whose high standard reduction potential leads to full‐cell voltages above 2.2 V at 200 mA/cm 2 . Here we explored an alternative anodic reaction, w...

Regional FireworksPollution over East and SoutheastAsia from Airborne Observations around the Spring Festival Period

Abstract Fireworks are spectacular, but they also pollute the atmosphere. While fireworks are known to rapidly increase local pollution levels, the regional influences and nanosized appearance of fireworks-related particles are poorly understood. This study collected aerosol part...

Graphitic Grain‐Network Nanoarchitecture for Ultrahigh‐Rate and Exceptionally Durable Potassium Ternary Intercalation

ABSTRACT Potassium–ternary graphite intercalation compounds (K + ‐T‐GICs) are promising high‐power potassium‐ion storage materials, but their low reversible capacity and poorly understood electrolyte‐dependent behavior have limited their practical viability. Herein, this sensitiv...

Epitactic Growthduring the Fluid-Driven Aragonite-to-CalciteTransformation

Abstract Aragonite and calcite (CaCO3) are the most abundant polymorphs of calcium carbonate in the Earth’s crust and are relevant industrial minerals. The factors that control the solid-state transformation of aragonite, the high-pressure polymorph, into calcite, the stable poly...
