SymTFT actions, condensable algebras and categorical anomaly resolutions
Abstract We investigate symmetry topological field theories (SymTFTs) of non-abelian and non-invertible symmetries and the different Lagrangian algebras associated with a given Drinfeld center. For several examples we analyze the condensable algebras of the Drinfeld center to identify the…

Decomposition and (non-invertible) (−1)-form symmetries from the symmetry topological field theory
Abstract We investigate the interplay between (−1)-form symmetries and their quantum-dual (d − 1)-form counterparts within the framework of Symmetry Topological Field Theories (SymTFTs). In this framework the phenomenon of decomposition — a d-dimensional quantum field theory with (d − 1)-form…

Spatial heterogeneity in the urban household living conditions: A-GIS-based spatial analysis
ABSTRACTThe unplanned urban expansion and extreme population pressure have caused several bottlenecks for city dwellers, which have been reflected in the form of inter-urban spatial inequality in living conditions at the household level. The present study integrates GIS with a composite synthetic…

Development, in-vitro and ex-vivo evaluation of HPMC E-15/Xanthan gum mucoadhesive buccal patch of telmisartan
Background: Telmisartan, an antihypertensive drug, exhibits poor aqueous solubility and low oral bioavailability due to extensive hepatic first-pass metabolism. Buccal delivery offers a potential alternative route to bypass first-pass metabolism and achieve sustained drug release for better blood…

Ice-patch collapse and early-warning implications from a Himalayan flash flood: emerging cryo-hydrological hazards under deglaciation
Abstract Emerging cryo-hydrological hazards linked to deglaciation are increasingly affecting high-mountain environments, yet their precursors remain poorly constrained. We investigate the 5 August 2025 flash flood at Dharali, Uttarkashi (Central Himalaya), and present evidence that it was…

Ferroptosis as an immunometabolic checkpoint in brain tumours: spatial vulnerabilities and therapeutic opportunities
Abstract Brain tumours, particularly glioblastoma, remain among the most lethal cancers due to considerable spatial variation, metabolic adaptability, immune suppression, and resistance to standard therapies. Ferroptosis, an iron-dependent form of regulated cell death driven by lipid peroxidation…
