Infinitesimal Structure of Singularities [PDF]
Universe, 2017 Some important problems of general relativity, such as the quantisation of gravity or classical singularity problems, crucially depend on geometry on very small scales.

Aspectos internos y externos de lógica continua y lógica categórica para haces sobre cuantales [PDF]
, 2023 In this text we explore and propose notions of sheaves over commutative, integral quantales, which are based on extensions of results of the theory of sheaves over locales: the interplay of sheaves as valued-sets and the analogy of sheaves as enriched ...

A Convenient Category of Domains [PDF]
, 2007 topological spaces, generalising the usual ω-continuous dcppos of domain theory. Our category supports all the standard constructions of domain theory, including the solution of recursive domain equations.

Geometrisation of first-order logic
, 2015 That every first-order theory has a coherent conservative extension is regarded by some as obvious, even trivial, and by others as not at all obvious, but instead remarkable and valuable; the result is in any case neither sufficiently well-known nor ...

Weather Regime Diversity, Transitions, and Trends Using Hexagonal Self‐Organizing Maps
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.Abstract Persistent atmospheric circulation patterns, or weather regimes, strongly modulate surface weather and extremes, yet their internal diversity, transitions, and trends remain less understood for North America. We apply a self‐organizing map (SOM) framework to represent North American weather regimes using daily 500‐hPa geopotential height ...

The FEBS Journal, Volume 293, Issue 7, Page 1951-1969, April 2026.midkine‐a (mdka), a pan‐injury response gene in vertebrates, is precisely regulated in the zebrafish telencephalon by a modular cis‐regulatory architecture. This control ensures proper expression during development, adult brain homeostasis, and regeneration.
