A comprehensive review of cluster methods for drug–drug interaction network

Quantitative Biology, Volume 14, Issue 1, March 2026.
Abstract The detection of drug–drug interaction (DDI) is crucial to the rational use of drug combinations. Experimentally, DDI detection is time‐consuming and laborious. Currently, researchers have developed a variety of computational methods to predict DDI.

The Turán problem for hypergraphs of fixed size [PDF]

, 2005
We obtain a general bound on the Turán density of a hypergraph in terms of the number of edges that it contains. If F is an r-uniform hypergraph with f edges we show that [pi](F) =3 and f->[infinity]

Traces of hypergraphs

Journal of the London Mathematical Society, 2019
Let $\text{Tr}(n,m,k)$ denote the largest number of distinct projections onto $k$ coordinates guaranteed in any family of $m$ binary vectors of length $n$. The classical Sauer-Perles-Shelah Lemma implies that $\text{Tr}(n, n^r, k) = 2^k$ for $k \le r$. While determining $\text{Tr}(n,n^r,k)$ precisely for general $k$ seems hopeless even for constant $r$,

Maximum Shattering

Journal of Combinatorial Designs, Volume 33, Issue 12, Page 456-470, December 2025.
ABSTRACT A family ℱ of subsets of [ n ] = { 1 , 2 , … , n } shatters a set A ⊆ [ n ] if for every A ′ ⊆ A, there is an F ∈ ℱ such that F ∩ A = A '. We develop a framework to analyze f ( n , k , d ), the maximum possible number of subsets of [ n ] of size d that can be shattered by a family of size k.

Rainbow connection numbers of some classes of s-overlapping r-uniform hypertrees with size t

AIMS Mathematics
The rainbow connection concept was developed to determine the minimum number of passwords required to exchange encrypted information between two agents. If the information exchange involves divisions managing more than two agents, the rainbow connection ...

On Quasi Cycles in Hypergraph Databases

IEEE Access, 2020
The notion of hypergraph cyclicity is important in numerous fields of application of hypergraph theory in computer science and relational database theory. The database scheme and query can be represented as a hypergraph.

Determination of the Optimal Window Size for the Spatial XOR Filter

Software: Practice and Experience, Volume 55, Issue 11, Page 1773-1784, November 2025.
ABSTRACT Introduction An XOR filter is a probabilistic data structure representing a set of keys for membership queries. Given a set X⊂𝒰 of n$$ n $$ keys, and hash functions h1,…,hk:𝒰→{1,…,m}, the filter relies on filling in an array H[1,…,m]$$ H\left[1,\dots, m\right] $$ such that, for all x∈X$$ x\in X $$, h1(x)⊕⋯⊕hk(x)$$ {h}_1(x)\oplus \cdots \oplus {

Current progress of digital twin construction using medical imaging

Journal of Applied Clinical Medical Physics, Volume 26, Issue 9, September 2025.
Abstract Medical imaging is fundamental to digital twin technology, enabling patient‐specific virtual models of anatomy and physiology. By integrating high‐resolution modalities (Magnetic Resonance Imaging (MRI), Computed Tomography (CT), Positron Emission Tomography (PET), ultrasound) with computational frameworks, recent imaging advances now support ...

Hypergraph Convolutional Network with Multi-perspective Topology Refinement forSkeleton-based Action Recognition [PDF]

Jisuanji kexue
Since the human skeleton is a natural topological structure,graph convolutional networks(GCNs) are widely used for skeleton-based human action recognition.In recent research,skeleton sequences are represented as spatio-temporal graphs and topology graphs
