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

Shaking‐Induced Small Seismic Velocity Changes as Revealed From Seismic Interferometry Analysis of Distributed Acoustic Sensing Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Understanding the spatio‐temporal variations in the physical properties of the Earth's crust is crucial for comprehending the dynamic processes linked to earthquakes. Conventional seismometer‐based analyses have limitations in spatio‐temporal resolution due to the sparse station distribution.

Numerical Anisotropy and Band‐Gap Formation in Finite Element Wave Propagation: Analysis and Mitigation Using Spline‐Based Elements

International Journal for Numerical Methods in Engineering, Volume 127, Issue 14, 30 July 2026.
ABSTRACT Numerical anisotropy and dispersion are inherent consequences of spatial discretization in finite element modeling of wave propagation. In two‐dimensional problems, these effects manifest not only as direction‐dependent phase and group velocities but also as angularly dependent numerical band gaps that may entirely suppress wave propagation ...

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, Volume 11, Issue 13, 8 July 2026.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Schema of the adjacency matrix.

, 2023
The elements of the adjacency matrix are the weights of links. Each row of the adjacency matrix contains the weights of in-links for the corresponding node, and the number of nonzero entries is its in-degree. Similarly, each column carries the weights of

Link Prediction with Swarms of Chiral Quantum Walks

Advanced Quantum Technologies, Volume 9, Issue 6, June 2026.
Network reconstruction is a fundamental problem in network biology. We propose a link prediction method based on a swarm of chiral quantum walks. Random phase assignments in each walker's Hamiltonian generator produce complementary dynamics on the same topology.

Modularity‐Preserving Hamiltonian Compression for QAOA‐Based Community Detection

Advanced Quantum Technologies, Volume 9, Issue 6, June 2026.
This work explores several quantum methods to community detection in networks by simplifying modularity‐based Hamiltonians. By reducing circuit complexity through sparsification, spectral projection, and penalty techniques, the methods retain key structural information while improving efficiency.
