ABSTRACT In this paper, we continue the development of the Cartan neural networks programme, launched with three previous publications, by focusing on some mathematical foundational aspects that we deem necessary for our next steps forward. The mathematical and conceptual results are diverse and span various mathematical fields, but the inspiring ...

ABSTRACT We propose a manifestly duality‐invariant, Lorentz‐invariant, and local action to describe quantum electrodynamics in the presence of magnetic monopoles that derives from Sen's formalism. By employing field strengths as the dynamical variables, rather than potentials, this formalism resolves longstanding ambiguities in prior frameworks.

End of the world boundaries for chiral quantum gravity theories
We describe the construction of large classes of explicit string theory backgrounds corresponding to 6d and 4d chiral theories with end of the world boundaries, and describe the strong coupling phenomena involved in gapping the chiral (but non-anomalous)

A note on D0-branes and instantons in 5d supersymmetric gauge theories
We refine a previous proposal for obtaining the multi-instanton partition function from the supersymmetric index of the 1d supersymmetric gauge theory on the worldline of D0-branes.

Synaptic vesicle (SV) motion and exocytosis dynamics in the presynaptic terminals of live neurons are intimately linked to synaptic transmission during neuronal activity. In this work, it is revealed that, during electrical stimulation, SVs located farther from their fusion sites exhibit greater straightness and experience larger mean forces directed ...

Balanced B and D-type orthosymplectic quivers — magnetic quivers for product theories
We investigate orthosymplectic quivers that take the shape of D-type and B-type Dynkin diagrams. The D-type orthosymplectic quivers explored here contain a balanced “fork”, i.e.

We calculate the algebra of constraints for deparametrized general relativity with a space‐time filling unstable D‐brane for an arbitrary value of tachyon field T. We also propose observables that have vanishing Poisson brackets with all first‐class constraints.

Extra Care Housing in the United Kingdom: A Systematic Scoping Review
Extra care housing (ECH) is a model of housing for older people where residents live in self‐contained accommodation with flexible care and support available 24/7. Whilst ECH may help people live independently for longer, its provision also poses challenges. This scoping review aimed to summarise empirical research relating to ECH in the United Kingdom

Calabi-Yau products: graded quivers for general toric Calabi-Yaus
The open string sector of the topological B-model on CY (m + 2)-folds is described by m-graded quivers with superpotentials. This correspondence generalizes the connection between CY (m + 2)-folds and gauge theories on the worldvolume of D(5 − 2m)-branes

Comments on the RG‐Flow in Open String Field Theory
Abstract We define a metric G$G$ on the KBc‐subalgebra modulo gauge and describe the worldsheet RG‐flow as the gradient flow of the action of cubic open string field theory, where the flow lines are kink‐solitons. In particular, for a constant tachyon the gradient flow equations are equivalent to the RG‐equations. Additionally, a more general family of
