Self-Monitoring Theranostic Nanomaterials for Biomedical Imaging and Cancer Therapy: Real-Time Visualization of Biodistribution, Payload Release, and Therapeutic Response

Theranostic nanomedicines integrate therapeutic delivery with diagnostic imaging, but many conventional platforms primarily visualize nanocarrier localization and provide limited information on whether the therapeutic payload has been released, the intended treatment mechanism ha...

Finite-Sample Inference for Exponential Competing Risks Under Combined Type-II Generalized Progressive Hybrid Censoring

Time-limited life tests may terminate before both competing failure causes are observed. We derive the finite-sample distributions of ordinary maximum likelihood estimators (MLEs) for two independent exponential risks under combined Type-II generalized progressive hybrid censorin...

Robust link prediction in heterogeneous graphs via diffusion-based generative fusion and relation-aware guidance

Link prediction in heterogeneous graphs, which captures both topological and semantic information in graph structures helps the discovery of meaningful relationships. However, several fundamental challenges of link prediction remain insufficiently addressed. First, real-world dat...

How dupe types shape product attitudes: the moderating role of funsumer orientation

This study examines how dupe type influences product attitude and whether funsumer orientation moderates this relationship. A between-subjects experiment was conducted with 184 university students in South Korea, who were randomly assigned to a design-similar or function-similar...

Influence of Diamine Structure on Chain Packing and H2/CH4 Transport in BTDA-Based Polyimide Membranes

Abstract Developing high-performance membranes for H2/CH4 separation is a critical imperative for the advancement of the hydrogen economy. However, conventional polymeric membranes often suffer from the intrinsic trade-off between permeability and selectivity, as well as the tech...

A Simple and Scalable Approach to High-Resolution Breathable Nanomesh Electrodes for Skin-Attachable Bioelectronics

Abstract Skin-attachable nanomesh electrodes with breathability and biocompatibility are promising for next-generation wearable healthcare systems. However, they face challenges to achieve reliable high-resolution micropatterning. Here, we propose a simple approach to fabricate b...

Analysis of multiply charged monomer and dimer ions of the amyloid β(1–28) peptide using electrospray ionization mass spectrometry and collision-induced dissociation

Tandem mass spectrometry (MS) fragmentation patterns of the Aβ1–28 monomer indicated that the entire 1–28 sequence dissociated during collision-induced dissociation (CID) process of the M 2+ , M 3+ , and M 4+ ions. Meanwhile, MS/MS analysis of the dimer showed that D 5+ dissociat...

Hydrogel-and-Nanomaterial-Integrated Wearable Biosensors for Real-Time Biomedical Monitoring: Materials, Devices, and IoT-Connected Systems

Hydrogel-and-nanomaterial-integrated wearable biosensor networks are promising platforms for real-time biomedical monitoring because they combine soft biointerfaces, sensitive signal transduction, and wireless data connectivity. Hydrogels provide tissue-like softness, hydration,...

Equivariant localization for wrapped M5-branes and D4-branes

A bstract Following the work of [1], we consider six- and seven-dimensional gauged supergravity coupled to a vector multiplet on an ansatz of AdS 4 , 5 × M 2 , respectively, where M 2 is a two-dimensional surface with a Killing vector. We construct equivariantly closed forms from...

Machine learning for early prediction of preterm birth

Abstract Background Preterm birth (PTB), defined as delivery before 37 completed weeks of gestation, remains a major cause of neonatal mortality and long-term morbidity worldwide. Conventional risk assessment strategies, including cervical length measurement and biomarker-based s...
