Denoising Diffusion Model With Pixel‐Adaptive Convolutions for Sheet Metal Forming Analysis
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.ABSTRACT Traditional tool development processes in mechanical forming, especially for pressing tools, are often limited by time‐consuming trial‐and‐error cycles, which rely heavily on expert knowledge. These cycles can create bottlenecks and increase costs.

Distributed Optimization of Finite Condition Number for Laplacian Matrix in Multi‐Agent Systems
International Journal of Robust and Nonlinear Control, Volume 36, Issue 9, Page 5030-5043, June 2026.ABSTRACT This paper addresses the distributed optimization of the finite condition number of the Laplacian matrix in multi‐agent systems. The finite condition number, defined as the ratio of the largest to the second smallest eigenvalue of the Laplacian matrix, plays an important role in determining the convergence rate and performance of consensus ...

Hierarchical certificateless authenticated key agreement protocol
Tongxin xuebao, 2016 A hierarchical certificateless authenticated key agreement protocol was proposed, and the proposed protocol was proved secure in extended Canetti-Krawczyk (eCK) model, the security of the protocol was based on the computa-tional Diffie-Hellman assumption.

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.Abstract Atmosphere‐ocean‐land coupled forecasting systems, despite their comprehensiveness, face substantial challenges in the “predictability desert” at subseasonal to seasonal (S2S) timescales, particularly for precipitation—a variable crucial for socioeconomic activities yet of stunning spatiotemporal variance. Post‐processing methods developed for

Journal of Flood Risk Management, Volume 19, Issue 2, June 2026.ABSTRACT Global warming has intensified the atmospheric water cycle, leading to more frequent and severe extreme precipitation events, which are a major driver of rainstorm‐induced flooding. Developing regions such as the China–Pakistan economic corridor (CPEC), spanning highly heterogeneous terrain and climate zones, face elevated risk due to limited ...

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract Urbanization can enhance local precipitation through thermodynamic and dynamic effects, yet detection of the urban rainfall island (URI) effect remains uncertain at the global scale because results vary across data sets, methods, and spatiotemporal resolutions.

(Not Surprising) Attacks on Recent Pairing-Free Attribute-Based Encryption Schemes
IET Information SecurityThe fact that designing secure and efficient identity or attribute-based encryption (ABE) schemes requires the use of specific algebraic tools like bilinear pairings or lattices is well known in the cryptographic community.

Interaction of Dirac δ$$ \delta $$‐Waves in the Inviscid Levine and Sleeman Chemotaxis Model
Mathematical Methods in the Applied Sciences, Volume 49, Issue 7, Page 6492-6506, 15 May 2026.ABSTRACT This article investigates interactions of δ$$ \delta $$‐shock waves in the inviscid Levine and Sleeman chemotaxis model ut−λ(uv)x=0$$ {u}_t-\lambda {(uv)}_x=0 $$, vt−ux=0$$ {v}_t-{u}_x=0 $$. The analysis employs a distributional product and a solution concept that extends the classical solution concept.
