Enumerating 6D supergravities with T ≤ 1
Journal of High Energy PhysicsThe space of 6D supergravities with minimal supersymmetry is greatly constrained by anomaly cancellation. Nevertheless, a large number of models satisfy all low-energy consistency conditions and in this work we make progress towards exhaustively ...

Empowering Public Health: AI‐Powered Security Solutions for AI‐Driven Challenges
Applied AI Letters, Volume 6, Issue 2, April 2025.ABSTRACT The escalating integration of artificial intelligence (AI) in public healthcare has raised a critical concern: the vast amounts of data being generated and utilised by AI language models are not adequately connected to privacy and security considerations.

Even-point multi-loop unitarity and its applications: exponentiation, anomalies and evanescence
Journal of High Energy PhysicsWe identify novel structure in newly computed multi-loop amplitudes and quantum actions for even-point effective field theories, including both the nonlinear sigma model (NLSM) and double-copy gauge theories such as Born-Infeld and its supersymmetric ...

Celestial Topology, Symmetry Theories, and Evidence for a NonSUSY D3‐Brane CFT
Fortschritte der Physik, Volume 73, Issue 4, April 2025.Abstract Symmetry Theories (SymThs) provide a flexible framework for analyzing the global categorical symmetries of a D$D$‐dimensional QFTD$\text{QFT}_{D}$ in terms of a (D+1)$(D+1)$‐dimensional bulk system SymThD+1$\text{SymTh}_{D+1}$. In QFTs realized via local string backgrounds, these SymThs naturally arise from dimensional reduction of the linking

Megapluvials in Southwestern North America
AGU Advances, Volume 6, Issue 2, April 2025.Abstract Droughts over the last century in Southwestern North America (SWNA) have had severe consequences for people and ecosystems across the region, most recently during the early 21st‐century megadrought (2000–2022). The 20th century, however, was bracketed by two extended pluvials that also had significant impacts in the region.

On Vertex Operators in Effective String Theory [PDF]
arXiv, 2017 In this note we construct vertex operators in effective string theory using the simplified covariant formalism, i.e. by embedding it in the Polyakov formalism supplemented by an anomaly term, and fixing to conformal gauge. These vertex operators represent off-shell background fields rather than dynamical string states. We construct vertex operators for

Earth and Space Science, Volume 12, Issue 4, April 2025.Abstract The biological pump, a fundamental process governing atmospheric CO2, rapidly transfers particulate inorganic and organic carbon (PIC and POC) from surface waters to the deep sea but is inherently highly variable in space and time, and thus poorly observed.
