Assembly of constructible factorization algebras

Journal of Topology, Volume 19, Issue 1, March 2026.
Abstract We provide a toolbox of extension, gluing, and assembly techniques for factorization algebras. Using these tools, we fill various gaps in the literature on factorization algebras on stratified manifolds, the main one being that constructible factorization algebras form a sheaf of symmetric monoidal ∞$\infty$‐categories.

Multi‐Scale Electrical Conductivity Model of the Contiguous United States

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract The completion of the Magnetotelluric (MT) USArray across the contiguous US enables continental‐scale 3‐D imaging of the asthenosphere‐lithosphere electrical structure. We present a novel 3‐D model of the contiguous United States (MECMUS), derived from a single inversion of the now‐completed USMTArray data set.

Quantum detection of boundary conditions

Physics Letters B
The quantum detection of spacetime conicity was investigated in reference Cong et al. (2021) [9] through the analysis of the response function of an Unruh-deWitt detector coupled to a massless scalar field.

Integral representations of solutions of coercive solvable problems for the Laplace equation

Boundary Value Problems
Modeling of many stationary physical processes is reduced to the study of boundary value problems for elliptic equations. Starting with the works of A.V. Bitsadze and A.A. Samarskiy, well-posed, but not necessarily boundary value problems for the Laplace
