Spatial Load Forecasting Based on RIME-Optimized Combination Modal Decomposition and Informer [PDF]

open access: yesDianli jianshe
[Objective] This paper proposes a spatial load forecasting method based on RIME-optimized combination modal decomposition and Informer to provide accurate load data for power system planning. [Methods] First, a power geographic information system for the

An ontological morphological phylogenetic framework for living and extinct ray‐finned fishes (Actinopterygii)

open access: yesThe Anatomical Record, EarlyView.
Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

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

open access: yesMathematische Nachrichten, EarlyView.
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

The Two Extremal Rays of Some Hyper–Kähler Fourfolds

open access: yesMathematische Nachrichten, EarlyView.
ABSTRACT We consider projective Hyper–Kähler manifolds of dimension 4 that are deformation equivalent to Hilbert squares of K3 surfaces. In case such a manifold admits a divisorial contraction, the exceptional divisor is a conic bundle over a K3 surface. A classification of lattice embeddings implies that there are five types of such conic bundles.

High‐Resolution Mapping of Discharge Product in Li─O2 Batteries

open access: yesSmall Methods, EarlyView.
Li─O2 batteries promise exceptional energy density, but have several factors limiting performance, such as poor rate performance. To understand rate limitations, scanning electron microscopy with energy dispersive X‐ray spectroscopy and X‐ray nano‐computed tomography were employed to map the distribution of discharge products in discharged air ...

A Non‐Parametric Framework for Correlation Functions on Product Metric Spaces

open access: yesInternational Statistical Review, EarlyView.
Summary We propose a non‐parametric framework for analysing data defined over products of metric spaces, a versatile class encountered in various fields. This framework accommodates non‐stationarity and seasonality and is applicable to both local and global domains, such as the Earth's surface, as well as domains evolving over linear time or time ...

Engineering Orbital Angular Momentum in Structured Beams in General Astigmatic Systems via Symplectic Matrix Approach

open access: yesPhotonics
We studied theoretically and experimentally the propagation of structured Laguerre–Gaussian (sLG) beams through an optical system with general astigmatism based on symplectic ABCD transforms involving geometry of the second-order intensity moments ...

Fourier Expansion‐Based Approach to the Parameter Space of Classical Systems

open access: yesAnnalen der Physik, Volume 538, Issue 7, July 2026.
ABSTRACT We propose a new approach to compute the classical metric tensor (CMT) and the Hannay curvature using Fourier series expansions in action‐angle variables. This approach circumvents the need for complex time‐domain integrals or the construction of generating functions, replacing them with algebraic combinations of Fourier coefficients. We prove

Reaction‐Driven Development of Fine‐Grained Plagioclase Networks Influences the Rheology of the Crust in the Bergen Arcs, Norway

open access: yesJournal of Metamorphic Geology, Volume 44, Issue 6, Page 470-491, July 2026.
ABSTRACT In the middle to lower continental crust, mineral reactions can play a key role in controlling rheological behaviour by generating fine‐grained, mechanically weak domains. In granulite‐facies rocks from Krossøy (Bergen Arcs, Norway), we document how garnet breakdown produced interconnected networks of orthopyroxene + plagioclase ± spinel that ...

A relative Poincaré–Birkhoff theorem

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 7, July 2026.
Abstract A. Moreno and Otto van Koert proved a generalised version of the classical Poincaré–Birkhoff theorem, for Liouville domains of any dimension. In this article, we prove a relative version for Lagrangians with Legendrian boundary. This gives interior chords of arbitrary large length, provided that the twist condition introduced by Moreno and van
