Mitochondria-Targeting Bismuth Selenide Nanoparticles for X-ray CT Imaging and Cancer Radiotherapy

Abstract Radiotherapy plays an indispensable role in clinical cancer treatment. Designing dual-modal agents for computed tomography (CT) imaging and radiotherapy sensitization remains a great challenge in tumor therapy. In this study, we designed and synthesized bismuth-based nan...

Differential effects of PM2.5 constituents on tuberculosis infection and disease progression in 40,379 student close contacts

Abstract Rationale Outdoor PM2.5 has been increasingly implicated in tuberculosis, yet evidence has largely focused on total PM2.5 mass and has usually considered Mycobacterium tuberculosis (M. tuberculosis) infection and active tuberculosis separately. Whether specific PM2.5 che...

Balancing adversariality and naturalness in autonomous vehicle testing scenario generation via multi-objective reinforcement learning

Reinforcement learning (RL)-based adversarial scenario generation through dynamic agent–environment interactions has emerged as a promising approach for accelerating autonomous vehicle (AV) testing. However, existing RL approaches struggle to balance adversariality and naturalnes...

Spmark: improving small-target text selection with smooth-pursuit gaze interaction in hybrid paper–digital environments

Precise text annotation on printed documents is essential for knowledge capture. While gaze-based interaction offers a hands-free approach, existing methods often suffer from low accuracy and ambiguous intent recognition in cluttered contexts. We propose SPMark, a hybrid gaze int...

Transforming Gas Separations with Scalable Carbon Molecular Sieve Membranes Enabled by Chemically Tuned Hollow‐Fiber Precursors

ABSTRACT Blending hydrogen into natural gas pipelines requires efficient separation, while helium recovery from natural gas via cryogenic distillation is energy‐ and capital‐intensive, driving demand for better membranes. This study develops ultraselective carbon molecular sieve...

Artificial intelligence–assisted integration of phase change material-embedded clay bricks for net-zero modular construction

Purpose This study develops an exploratory artificial intelligence (AI)-assisted framework for integrating phase change material (PCM)-embedded clay bricks into modular wall assemblies to support net-zero building performance. The work addresses the current absence of scalable, c...

Active Blood Cell Capture and Synergistic Coassembly: Self-Gelling Gelatin-Polysaccharide Powders for Rapid Hemostasis

While effective for irregular wounds, traditional hemostatic powders often lack posthydration cross-linking, yielding fragile barriers susceptible to washout under high-pressure hemorrhage. To address this, a novel self-gelling composite powder (GOQL) was developed by incorporati...

Dynamic Response of Saturated Kaolin Clay under Repeated Impact Loading

The dynamic response mechanism of clayey foundations under impact loading remains insufficiently understood. This study investigates the dynamic behavior of saturated kaolin clay under repeated one-dimensional impacts using an improved Split Hopkinson pressure bar (SHPB) apparatu...

Does the national sustainable development plan for resource-based cities promote inclusive green growth in both “quantity” and “quality”?

Purpose In China, resource-based cities, being of vital significance for energy and resources, are confronted with severe threats such as depletion, environmental deterioration, and economic disequilibrium. Inclusive green growth, in response to the two predominant global trends...

Optimal estimators and tests for reciprocal effects

The $p_1$ model plays a fundamental role in modeling directed networks, where the reciprocal effect parameter $ρ$ is of special interest in practice. However, due to nonlinear factors in this model, how to estimate $ρ$ efficiently is a long-standing open problem. We tackle the pr...

Triplet Exciton Convergence toward Charge-Transfer States Enables Long-Wavelength Room-Temperature Phosphorescence from Carbon Dots

Abstract Long-wavelength room-temperature phosphorescent carbon dots (CDs), especially the red phosphorescent ones, have garnered significant attention due to their low-energy emission and potential applications. However, the achievement of red phosphorescence in CDs presents a s...

Deep Transformation Model

The increasing data complexity leads to the demand for more general and flexible modeling approaches. We consider a nonparametric transformation model with weak assumptions, which encompasses many popular models as special cases. A rank-based deep neural network (DNN) estimation...

Integrated safety-critical motion planning and control strategy for emergency lane changes of autonomous vehicles

Autonomous driving requires the integration of perception, decision-making, planning, and control. Learning-based perception and decision-making methods often suffer from a lack of interpretability, making it necessary to revisit safety-critical autonomous driving technologies in...

Negative Interfacial Tension Driven by Intrinsic Molecular Disorder

Abstract Intrinsically disordered molecular systems, such as random copolymers and intrinsically disordered proteins, exhibit scale-invariant, power-law cluster distributions that cannot be explained by conventional mean-field theories. A fundamental challenge is to understand ho...

Random Copolymer Acceptors for Efficient Small-Molecule Donor/Polymer Acceptor Organic Solar Cells

Abstract Small-molecule donor/polymer acceptor (SD/PA) organic solar cells (OSCs) are attractive for their morphological stability, yet their efficiencies still lag behind those of mainstream systems. One key difficulty is that the acceptor must aggregate strongly enough to form...

Gene-brain-behavior links revealing generative neurophysiological subtypes of suicide-related dysconnectivity in bipolar depression

Suicidal thoughts and behaviors (STBs) in bipolar depression are heterogeneous, but biologically coherent subtypes remain poorly defined. We aimed to identify neurophysiological subtypes of suicide-related dysconnectivity in bipolar depression and examine their gene-brain-behavio...

Multidentate Coordination Enables Coupled Bulk Solvation and Interfacial Regulation for Stable Zinc Metal Anodes

ABSTRACT Aqueous Zn metal batteries are fundamentally constrained by the coupled instability of Zn 2+ solvation chemistry and interfacial reactions, which induces parasitic side reactions and non‐uniform Zn deposition. Here, we report a multidentate‐coordination electrolyte strat...
