Assimilation of Atmospheric CO2 Concentration in the ORCHIDEE Land Surface Model: Exploring the Added Value of Explicit Forest Regrowth Representation

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 9, September 2026.
Abstract The land absorbs a large proportion of human‐induced carbon emissions, yet the spatial distribution of this carbon sink remains uncertain. Land surface models (LSMs) and atmospheric inversions often diverge on the spatial distribution of carbon sink, with models generally underestimating the northern land sink (above 30°N).

An Eikonal‐Based Angle‐Domain Least‐Squares Kirchhoff Depth Migration in General Anisotropic Media

Geophysical Prospecting, Volume 74, Issue 7, September 2026.
ABSTRACT Least‐squares migration (LSM) is an inversion‐based imaging method that seeks a reflectivity model whose predicted data best fit the recorded seismic data in a least‐squares sense. However, conventional LSM can be unreliable for anisotropic reflection data if reflection angles are neglected.

When weak convergence in von Neumann algebras implies almost uniform convergence?

Bulletin of the London Mathematical Society, Volume 58, Issue 9, September 2026.
Abstract We show that weak sequential convergence in a semifinite von Neumann algebra M$\mathcal {M}$ equipped with a faithful normal semifinite trace τ$\tau$ implies almost uniform convergence if and only if M$\mathcal {M}$ is of type Ifin$\mathrm{I}_{\rm fin}$ with τ(1)<∞;$\tau (\mathbf {1})<\infty;$ and that weak sequential convergence in a finite ...

Uniqueness problem for accretive Schrödinger operators with complex singular coefficients

Bulletin of the London Mathematical Society, Volume 58, Issue 9, September 2026.
Abstract This paper studies the uniqueness problem for the one‐dimensional Schrödinger operator associated with the formal differential expression l[u]=−u′′+qu+i[(ru)′+ru′]$l[u] =-u^{\prime \prime }+qu + i[(ru)^{\prime }+ru^{\prime }] $ in the complex Hilbert space L2(R)$L^{2}(\mathbb {R})$.

Isometric immersions into three‐dimensional unimodular metric Lie groups

Journal of the London Mathematical Society, Volume 114, Issue 3, September 2026.
Abstract We study isometric immersions of surfaces into simply connected three‐dimensional unimodular Lie groups endowed with either Riemannian or Lorentzian left‐invariant metrics, assuming that Milnor's operator is diagonalizable in the Lorentzian case.
