Self-complementary hypergraphs and their self-complementing permutations

open access: yesElectronic Notes in Discrete Mathematics, 2006
Abstract A k –uniform hypergraph H = ( V ; E ) is called self-complementary if there is a permutation σ : V → V , called self-complementing , such that for every k –subset e of V , e ∈ E if and only if σ ( e ) ∉ E . In other words, H is isomorphic with H ′ = ( V ; ( V k ) −

A note on self-complementary 4-uniform hypergraphs [PDF]

open access: yesOpuscula Mathematica, 2005
We prove that a permutation \(\theta\) is complementing permutation for a \(4\)-uniform hypergraph if and only if one of the following cases is satisfied: (i) the length of every cycle of \(\theta\) is a multiple of \(8\), (ii) \(\theta\) has \(1\), \(2\)

SPLHRNMTF: robust orthogonal non-negative matrix tri-factorization with self-paced learning and dual hypergraph regularization for predicting miRNA-disease associations [PDF]

open access: yesBMC Genomics
MicroRNAs (miRNAs) have been demonstrated to be closely related to human diseases. Studying the potential associations between miRNAs and diseases contributes to our understanding of disease pathogenic mechanisms.

Cyclic Partitions of Complete and Almost Complete Uniform Hypergraphs

open access: yesDiscussiones Mathematicae Graph Theory, 2022
We consider cyclic partitions of the complete k-uniform hypergraph on a finite set V, minus a set of s edges, s ≥ 0. An s-almost t-complementary k-hypergraph is a k-uniform hypergraph with vertex set V and edge set E for which there exists a permutation ...

A family of \(t\)-regular self-complementary \(k\)-hypergraphs

open access: yesTransactions on Combinatorics, 2017
Summary: We use the recursive method of construction large sets of \(t\)-designs given by \textit{Q.-r. Wu} [Australas. J. Comb. 4, 229--235 (1991; Zbl 0763.05013)], and present a similar method for constructing \(t\)-subset-regular self-complementary \(k\)-uniform hypergraphs of order \(v\). As an application we show the existence of a new family of 2-

A note on 2-subset-regular self-complementary 3-uniform hypergraphs

open access: yesArs Comb., 2008
We show that a 2-subset-regular self-complementary 3-uniform hypergraph with $n$ vertices exists if and only if $n\ge 6$ and $n$ is congruent to 2 modulo 4.

Topology‐Aware Deep Learning on Higher‐Order Structures for Drug Response Prediction

open access: yesAdvanced Science, EarlyView.
We present TopDr, a topology‐aware deep learning framework that encodes both drugs and cell lines as multiscale simplicial complexes, capturing interactions at the 0‐, 1‐, and 2‐simplex levels. By jointly integrating local higher‐order neighborhoods and global topological structures, TopDr generates enriched representations for sensitivity prediction ...

Land Use and Land Cover Analysis for Solid Waste Management in NCT Delhi Using Fusion Aware Segformer

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT The use of Land Use Land Cover (LULC) analysis is a fundamental requirement for urban solid waste management (SWM); however, conventional LULC analysis methods are not well suited to the spatio‐temporal variability, multi‐sensor heterogeneity, and seasonal variations of highly dynamic urban environments.
