2-Rényi CCNR negativity of compact boson for multiple disjoint intervals

Journal of High Energy Physics
We investigate mixed-state bipartite entanglement between multiple disjoint intervals using the computable cross-norm criterion (CCNR). We consider entanglement between a single interval and the union of remaining disjoint intervals, and compute 2-Rényi ...

The Serre duality theorem for Reimann surfaces

International Journal of Mathematics and Mathematical Sciences, 1984
Given a Riemann surface S, there exists a finitely generated Fuchsian group G of the first kind acting on the upper half plane U, such that S≅U/G. This isomorphism makes it possible to use Fuchsian group methods to prove theorems about Riemann surfaces ...

Kuga–Satake Construction on Families of K3 Surfaces of Picard Rank 14

Mathematische Nachrichten, Volume 299, Issue 8, Page 1894-1916, August 2026.
ABSTRACT The isometry between the type IV6 and the type II4 hermitian symmetric domains suggests a possible relation between suitable moduli spaces of K3 surfaces of Picard rank 14 and of polarized abelian 8‐folds with totally definite quaternion multiplication. We show how this isometry induces a geometrically meaningful map between such moduli spaces

Feasibility of convection‐enhanced delivery of unlabeled 225Ac for glioblastoma: Transport, dosimetry, and clonogenic survival modeling

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Glioblastoma (GB) is an aggressive primary brain tumor with local recurrence rates exceeding 90% and a five‐year survival rate of approximately 5%. Standard treatments such as surgical resection, external beam radiotherapy (EBRT), and chemotherapy often leave residual tumor cells that are resistant to therapy.

Higher genus polylogarithms on families of Riemann surfaces

Nuclear Physics B
We construct polylogarithms on families of pointed Riemann surfaces of any genus which describe monodromies of nilpotent meromorphic connections with simple poles on these families.

Vortices for lake equations: Review with questions and speculations [PDF]

Theoretical and Applied Mechanics
The ‘lake equation’ on a planar domain $ D $ with bathymetry $ b(x, y) $ is given by $ \partial_t u + (u \cdot grad)u = -grad p $, $ \operatorname{div}(bu) = 0 $, with $ u \parallel \partial D $.

Intrinsic Shape LDA With Application to Body Human Shapes Classification

Statistical Analysis and Data Mining: An ASA Data Science Journal, Volume 19, Issue 4, August 2026.
ABSTRACT Advancements in 3D scanning and cloud infrastructure enable the acquisition and analysis of high‐density body surface datasets. In this work, we propose a novel methodology that extends linear discriminant analysis (LDA) to Kendall's shape space for the classification of 3D objects, specifically human body shapes.

Three-form periods on Calabi-Yau fourfolds: toric hypersurfaces and F-theory applications

Journal of High Energy Physics, 2017
The study of the geometry of Calabi-Yau fourfolds is relevant for compactifications of string theory, M-theory, and F-theory to various dimensions. This work introduces the mathematical machinery to derive the complete moduli dependence of the periods of

Learning Vertical Coordinates via Automatic Differentiation of a Dynamical Core

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract Terrain‐following coordinates in atmospheric models often imprint their grid structure onto the solution, particularly over steep topography, where distorted coordinate layers can generate spurious horizontal and vertical motion. Standard formulations, such as hybrid or SLEVE coordinates, mitigate these errors by using analytic decay functions
