Motivic renormalization and singularities [PDF]

, 2009
We consider parametric Feynman integrals and their dimensional regularization from the point of view of differential forms on hypersurface complements and the approach to mixed Hodge structures via oscillatory integrals.

Deep Graph Laplacian Regularization for Robust Denoising of Real Images

, 2019
Recent developments in deep learning have revolutionized the paradigm of image restoration. However, its applications on real image denoising are still limited, due to its sensitivity to training data and the complex nature of real image noise.

De Novo Multi‐Mechanism Antimicrobial Peptide Design via Multimodal Deep Learning

Advanced Science, EarlyView.
Current AI‐driven peptide discovery often overlooks complex structural data. This study presents M3‐CAD, a generative pipeline that leverages 3D voxel coloring and a massive database of over 12 000 peptides to capture nuanced physicochemical contexts.

Hyperspectral Anomaly Detection via Low-Rank Representation with Dual Graph Regularizations and Adaptive Dictionary

Remote Sensing
In a hyperspectral image, there is a close correlation between spectra and a certain degree of correlation in the pixel space. However, most existing low-rank representation (LRR) methods struggle to utilize these two characteristics simultaneously to ...

Nonlinear and oblique boundary value problems for the Stokes equations

Electronic Journal of Qualitative Theory of Differential Equations, 2011
In this paper we consider the nonlinear boundary value problem governed by a stationary perturbed Stokes system with mixed boundary conditions (Dirichlet- maximal monotone graph), in a smooth domain.

Semantic Consistency Cross-Modal Retrieval With Semi-Supervised Graph Regularization

IEEE Access, 2020
Most of the existing cross-modal retrieval methods make use of labeled data to learn projection matrices for different modal data. These methods usually learn the original semantic space to bridge the heterogeneous gap, ignoring the rich semantic ...

Factorizations of regular graphs

Journal of Combinatorial Theory, Series B, 1992
Let G be a k-regular graph of order 2n such that \(k\geq n\). \textit{A. J. W. Hilton} [J. Graph Theory 9, 193-196 (1985; Zbl 0624.05050)] proved that G contains at least \(\lfloor k/3\rfloor\) edge-disjoint 1-factors. Hilton's theorem is improved in this paper that G contains at least \(\lfloor k/2\rfloor\) edge-disjoint 1-factors.

In Situ X‐Ray Tomography and Acoustic Emission Monitoring of Damage Evolution in C/C‐SiC Composites Fabricated by Liquid Silicon Infiltration

Advanced Science, EarlyView.
This study investigates how the internal structure of fiber‐reinforced ceramic composites affects their resistance to damage. By combining 3D X‐ray imaging with acoustic emission monitoring during mechanical testing, it reveals how silicon distribution influences crack formation.

Accounting for apparatus function when registering experimental data: peculiarity of choosing regularization parameter by L-curve criterion at deconvolution of the spectrum

Ядерна фізика та енергетика, 2019
Within the framework of the problem of spectrum deconvolution, variant of the choice of the regularization parameter by criterion of the L-curve, based on the displacement along the points of the L-curve graph, is proposed. An analysis of dependencies on
