On the freeness of hypersurface arrangements consisting of hyperplanes and spheres
, 2018 Let V be a smooth variety. A hypersurface arrangement in V is a union of smooth hypersurfaces, which locally looks like a union of hyperplanes. We say is free if all these local models can be chosen to be free hyperplane arrangements. In this paper, we

International Journal of Intelligent Systems, Volume 2026, Issue 1, 2026.Semisupervised multilabel classification faces significant challenges due to limited labeled data, label overlap, and high‐dimensional feature spaces. To address these challenges, this paper proposes a unified framework that integrates relaxed graph Laplacian‐based label propagation with gain ratio‐based feature selection and a multilabel support ...

Dynamic point location in arrangements of hyperplanes
, 1992 We present algorithms for maintaining data structures supporting fast (polylogarithmic) point-location and ray-shooting queries in arrangements of hyperplanes. This data structure allows for deletion and insertion of hyperplanes.

Asymptotic Bayesian Decision Feedback Equalizer Using a Set of Hyperplanes
, 2000 We present a signal space partitioning technique for realizing the optimal Bayesian decision feedback equalizer (DFE). It is known that, when the signal to noise ratio (SNR) tends to infinity, the decision boundary of the Bayesian DFE is asymptotically ...

Journal of Engineering, Volume 2026, Issue 1, 2026.Infrastructure construction and maintenance is very critical in supporting a robust and sustainable transportation system. The primary goal of transportation infrastructure is to ensure safe and efficient movement. However, aging, traffic loads, and environmental conditions all lead to distress on pavement that necessitates the use of predictive models

Journal of Electrical and Computer Engineering, Volume 2026, Issue 1, 2026.Celiac disease is a chronic autoimmune disorder that primarily affects individuals genetically predisposed to it, causing damage to the small intestine upon gluten consumption. Although it affects around one person out of every hundred worldwide, celiac disease is frequently misdiagnosed. Eliminating serious health problems from celiac disease requires

Equivariant Hilbert and Ehrhart series under translative group actions
Journal of the London Mathematical Society, Volume 112, Issue 5, November 2025.Abstract We study representations of finite groups on Stanley–Reisner rings of simplicial complexes and on lattice points in lattice polytopes. The framework of translative group actions allows us to use the theory of proper colorings of simplicial complexes without requiring an explicit coloring to be given.

The integer cohomology of toric Weyl arrangements [PDF]
A toric arrangement is a finite set of hypersurfaces in a complex torus, every hypersurface being the kernel of a character. In the present paper we prove that if T(W) is the toric arrangement defined by the cocharacters lattice of a Weyl group W, then ...

Corrections of Electron–Phonon Coupling for Second‐Order Structural Phase Transitions
physica status solidi (b), Volume 262, Issue 10, October 2025.The left image illustrates a weak electron–phonon coupling, while the right image depicts a strong electron–phonon coupling. The weak electron–phonon coupling interaction between the lattice and electrons is susceptible to destabilization by an increase in temperature.

The homotopy type of toric arrangements [PDF]
A toric arrangement is a finite set of hypersurfaces in a complex torus, every hypersurface being the kernel of a character. In the present paper we build a CW-complex S homotopy equivalent to the arrangement complement ℜ x, with a combinatorial ...
