Broadcasting‐induced colorings of preferential attachment trees

open access: yes, 2023
We consider random two-colorings of random linear preferential attachment trees, which includes recursive trees, plane-oriented recursive trees, binary search trees, and a class of d-ary trees.

Trees in random graphs

open access: yesDiscrete Mathematics, 1983
The probability space consisting of all graphs on a set of \(n\) vertices where each edge occurs with probability \(p\), independently of all other edges, is denoted by \(G(n,p)\). Theorem: For each \(\epsilon>0\) almost every graph \(G\in G(n,p)\) is such if \((1+\epsilon)\log n/\log ...

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Random walk with barycentric self-interaction [PDF]

open access: yes, 2011
We study the asymptotic behaviour of a $d$-dimensional self-interacting random walk $X_n$ ($n = 1,2,...$) which is repelled or attracted by the centre of mass $G_n = n^{-1} \sum_{i=1}^n X_i$ of its previous trajectory. The walk's trajectory $(X_1,...,X_n)

Random hyperplane search trees in high dimensions

open access: yesJournal of Computational Geometry, 2015
Given a set S of n ≥ d points in general position in Rd, a random hyperplane split is obtained by sampling d points uniformly at random without replacement from S and splitting based on their affine hull. A random hyperplane search tree is a binary space

An Intrusion Detection Model Based on Random Tree Algorithm with Dimensionality Reduction and Oversampling

open access: yesJournal of Computing and Information Technology, 2023
With the advancement of the university information process, more and more application systems are running on the campus network, and the information system becomes larger and more complex. With the rapid growth of network users and the popularization and

Single‐cell DNA methylation profiling: Technologies, computation, and applications in precision oncology

open access: yesMolecular Oncology, EarlyView.
Single‐cell DNA methylation (scDNAme) profiling maps epimutational clonal evolution, revealing mechanisms of malignancy and therapeutic resistance across diverse cancer types. By providing a high‐resolution landscape of intratumoral heterogeneity, these technologies empower precise patient stratification, guide the development of enhanced ...

Predicting the Pillar Stability of Underground Mines with Random Trees and C4.5 Decision Trees

open access: yesApplied Sciences, 2020
Predicting pillar stability in underground mines is a critical problem because the instability of the pillar can cause large-scale collapse hazards. To predict the pillar stability for underground coal and stone mines, two new models (random tree and C4 ...

Label-based parameters in increasing trees [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2006
Grown simple families of increasing trees are a subclass of increasing trees, which can be constructed by an insertion process. Three such tree families contained in the grown simple families of increasing trees are of particular interest: $\textit ...

Refinement of amino‐acid conformation vs. difference density maps in time‐resolved serial femtosecond crystallography data analysis

open access: yesFEBS Open Bio, EarlyView.
The dFoCC pipeline starts with observed DED and resting‐state coordinates, which are then used to generate a library of triggered states. Correlation analysis of the calculated DED features of each candidate vs observed DED permits quantitative evaluation of candidate structural quality.
