Solving a Random Asymmetric TSP Exactly in Quasi‐Polynomial Time W.H.P.

open access: yesRandom Structures &Algorithms, Volume 68, Issue 2, March 2026.
ABSTRACT Let the costs C(i,j)$$ C\left(i,j\right) $$ for an instance of the Asymmetric Traveling Salesperson Problem (ATSP) be independent copies of a nonnegative random variable C$$ C $$ from a class of distributions that include the uniform [0,1]$$ \left[0,1\right] $$ distribution and the exponential mean 1 distribution with mean 1.

Securing the Unseen: A Comprehensive Exploration Review of AI‐Powered Models for Zero‐Day Attack Detection

open access: yesExpert Systems, Volume 43, Issue 3, March 2026.
ABSTRACT Zero‐day exploits remain challenging to detect because they often appear in unknown distributions of signatures and rules. The article entails a systematic review and cross‐sectional synthesis of four fundamental model families for identifying zero‐day intrusions, namely, convolutional neural networks (CNN), deep neural networks (DNN ...

Unravelling Twin Births in German Holstein Cows: Phenotypic Associations, Genetic Analysis and Potential Underlying Genes and Hormones

open access: yesJournal of Animal Breeding and Genetics, Volume 143, Issue 2, Page 213-222, March 2026.
ABSTRACT Twin births in dairy cattle are rare but present significant challenges for animal welfare, as both the health of the cow and the calves are affected. This causes economic losses, which prompts breeders to select against twin births and identify associated risk factors.

Entrepreneurial Experience and Growth Aspirations: The Moderating Role of National Research & Development Expenditure

open access: yesR&D Management, Volume 56, Issue 2, Page 278-306, March 2026.
ABSTRACT This study examines the impact of entrepreneurial experience on growth aspirations and explores how a country's knowledge generation influences this relationship. Drawing on human capital theory, we first argue that diverse prior entrepreneurial experiences affect growth aspirations differently.

Data‐Driven Multi‐Objective Optimization of Large‐Diameter Si Floating‐Zone Crystal Growth

open access: yesAdvanced Theory and Simulations, Volume 9, Issue 2, February 2026.
This study presents a surrogate‐based Multi‐Objective Optimization framework for Floating Zone silicon crystal growth. An ensemble of Neural Networks is trained on simulation data and combined with Genetic Algorithms to explore trade‐offs in process parameters.
