High–spatiotemporal resolution deuterium metabolic imaging enables in vivo phenotyping of intra- and intertumoral heterogeneity

Intra- and intertumoral heterogeneities raise fundamental biological questions and have important implications for accurate cancer diagnosis, prognosis, and treatment. These heterogeneities reflect tumor complexity, including a pronounced diversity in metabolic phenotypes and pro...

Computational Oncology of Chemotaxis-Driven Tumour–Immune Spatial Patterning and Stability

We develop a reaction–diffusion–chemotaxis model for spatial tumour–immune–chemokine dynamics that couples logistic tumour growth, immune-mediated killing, chemokine-dependent immune recruitment, chemotactic migration, and signal production. For the non-dimensional system, we est...

Superconducting Hydride Mg2RhH6 Experimentally Achieved at Lower Pressure

Abstract Although tremendous progress has been made in recent years in the field of polyhydride superconductors, the realization of high critical temperature (Tc) superconductivity still relies on formidable high pressures. Searching for superconducting hydrides at lower pressure...

Ionic Liquid-Mediated Structure-Engineered Cellulose-Based Ionogel with Ion-Electron Cotransport for Boosted Thermoelectric Conversion

Abstract Low-grade heat (<373 K) remains an underutilized energy source due to inefficient conversion technologies. While ionic thermoelectric (i-TE) materials show promise for direct thermal-to-electrical energy conversion, simultaneously optimizing the conductivity and Seebeck...

Gate-imprinted memory and light-induced erasure of superconductivity at KTaO3-based interfaces

Realizing non-volatile control of superconductivity is a key step toward integrating memory and quantum functionality in future information technologies. KTaO₃-based heterostructures uniquely host interfacial two-dimensional superconductivity and quantum paraelectric lattice back...
