Responsive nanoheterojunctions for built‐in electric field‐promoted cascade tumor targeting and cuproptosis‐based therapy

Responsive Materials, EarlyView.
Nanoheterojunctions have been synthesized as responsive biomaterials for cascade targeting of tumor cells and mitochondria, ROS‐mediated apoptosis and Cu‐promoted cuproptosis. And drug‐device‐field integration as an advanced paradigm of tumor treatment was employed for photo‐triggered tumor cell elimination in vitro and lesion eradication in vivo ...

Nature‐Inspired Histidine and Guanidine Modification of Magnetic Nanoparticles for Urinary DNA Liquid Biopsy

Small Methods, EarlyView.
Nature‐inspired bi‐functionalized magnetic nanoparticles are engineered for the rapid, non‐invasive extraction of cell‐free DNA from unprocessed urine for liquid biopsy. These cationic particles leverage electrostatic interactions to outperform conventional kits, enhancing the recovery of short DNA fragments while maintaining DNA integrity.

A Novel Approach to Energy Management in Electric Steelworks

steel research international, EarlyView.
Feed‐forward neural networks are exploited to estimate electric energy consumptions of the electric arc furnace and ladle furnace processes. The models are used to optimize production schedule so that more energy intensive grades are produced when the cost of energy is lower.

Exterior Dirichlet Problem for Translating Solutions of Gauss Curvature Flow in Minkowski Space

Abstract and Applied Analysis, 2014
We prove the existence of solutions to a class of Monge-Ampère equations on exterior domains in ℝn(n≥2) and the solutions are close to a cone. This problem comes from the study of the flow by powers of Gauss curvature in Minkowski space.

Trajectories of refraction and strabismus from 2.5 to 12 years in a national cohort of extremely preterm children‐ the Extremely Preterm Infants in Sweden Study (EXPRESS)

Acta Ophthalmologica, EarlyView.
Abstract Purpose To investigate the longitudinal development of refraction and strabismus in a national cohort of children born extremely preterm (EPT) and find relations to perinatal events and neurodevelopmental outcomes. Methods All surviving children born <27‐gestation weeks in Sweden during April 2004–March 2007, and full‐term born matched ...

A balance between stability and flexibility: Adaptive patterns of self‐regulated learning processes shape game‐based learning

British Journal of Educational Technology, EarlyView.
Abstract To ensure learning efficiency in game‐based learning (GBL), learners must regulate cognitive, affective, metacognitive and motivational (CAMM) processes, collectively known as self‐regulated learning (SRL). SRL is dynamic and non‐linear, characterized by regulatory patterns and CAMM interactions that lead to macro‐level SRL behaviours. In this

Composite marginal likelihood estimation of higher‐order diagnostic classification models under high dimensionality

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Although full‐information maximum likelihood (FIML) estimation is widely used for diagnostic classification models (DCMs), its computational efficiency deteriorates sharply in high‐dimensional settings. This scalability challenge is increasingly critical as DCMs are applied to large‐scale assessments, psychological testing and longitudinal ...

On the asymmetry, complexity and predicted data patterns of nontraditional item response theory models

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Traditional item response theory (IRT) models involve symmetric response probability functions, but a developing area of research has focused on asymmetric alternatives. To date, these studies have focused primarily on introducing new asymmetric models, detailing their mathematical formulations, explaining how to interpret their item ...
