Advanced Physics Research, Volume 5, Issue 7, July 2026.ABSTRACT We introduce a family of bosonic quantum error‐correcting codes built as a rotation‐symmetric superposition of squeezed vacuum states, which promise protection against both loss and dephasing noise channels. The robustness of these “squeezed‐vacuum codes” arises from being arranged at evenly spaced angles in phase‐space, and simultaneously in ...

Revocable and Traceable Data Sharing and Encryption Methods in Cloud Computing Environments
Engineering Reports, Volume 8, Issue 7, July 2026.This paper proposes a revocable, traceable cloud data sharing scheme. It enhances multi‐authority attribute‐based encryption for fine‐grained access with immediate user revocation and precise leak tracking. Evaluations on a manufacturing platform show efficient performance, handling 1 GB files with re‐encryption under 4.3 s and strong privacy ...

Four‐Dimensional pp‐Wave Lie Groups and Harmonic Curvature
Mathematische Nachrichten, Volume 299, Issue 7, Page 1751-1780, July 2026.ABSTRACT We determine all four‐dimensional Lie groups which have harmonic curvature. In parallel, a description of four‐dimensional pp‐wave Lie groups is obtained.

A Novel Sequential Monte Carlo Algorithm for Parameter Estimation in Eco‐Hydrological Models
Water Resources Research, Volume 62, Issue 7, July 2026.Abstract Bayesian inference offers a flexible framework for parameter estimation and uncertainty quantification in eco‐hydrological models. However, simultaneously achieving robust posterior exploration and high computational efficiency for multimodal, high‐dimensional, and computationally intensive targets remains challenging for the widely used ...

The Zarankiewicz problem on tripartite graphs
Journal of the London Mathematical Society, Volume 114, Issue 1, July 2026.Abstract In 1975, Bollobás, Erdős, and Szemerédi asked for the smallest τ$\tau$ such that an n×n×n$n \times n \times n$ tripartite graph with minimum degree n+τ$n + \tau$ must contain Kt,t,t$K_{t, t, t}$, conjecturing that τ=O(n1/2)$\tau = \mathcal {O}(n^{1/2})$ for t=2$t = 2$.

On the Lang–Trotter conjecture for Siegel modular forms
Mathematika, Volume 72, Issue 3, July 2026.Abstract Let f$f$ be a genus‐two cuspidal Siegel eigenform. We prove an adelic open image theorem for the compatible system of Galois representations associated with f$f$, generalizing the results of Ribet and Momose for elliptic modular forms. Using this result, we investigate the distribution of the Hecke eigenvalues ap$a_p$ of f$f$, and obtain upper

New results on embeddings of self‐similar sets via renormalization
Proceedings of the London Mathematical Society, Volume 133, Issue 1, July 2026.Abstract For self‐similar sets X,Y⊆R$X,Y\subseteq \mathbb {R}$, we obtain new results toward the affine embeddings conjecture of Feng–Huang–Rao (2014), and the equivalent weak intersections conjecture. We show that the conjecture holds when the defining maps of X,Y$X,Y$ have algebraic contraction ratios, and also for arbitrary Y$Y$ when the maps ...
