Causal Effect Estimation With TMLE: Handling Missing Data and Near Violations of Positivity

Biometrical Journal, Volume 68, Issue 3, June 2026.
ABSTRACT We evaluate the performance of targeted maximum likelihood estimation (TMLE) for estimating the average treatment effect in missing data scenarios under varying levels of positivity violations. We employ model‐ and design‐based simulations, with the latter using undersmoothed highly adaptive lasso on the “WASH Benefits Bangladesh” data set to ...

Fairness at Risk: Where Bias Emerges in Machine Learning

Expert Systems, Volume 43, Issue 6, June 2026.
ABSTRACT Artificial intelligence and machine learning (ML) now shape decisions in healthcare, finance and security, but they can reproduce historical prejudice and inequality. Bias in training data and in model implementation can amplify harm, especially for racial and gender minorities.

Arbitrary precision real arithmetic: design and algorithms

, 2003
Nous proposons une représentation des nombres réels calculables ainsi que des algorithmes pour les fonctions élémentaires usuelles pour cette représentation.Un nombre réel est représenté par une suite de nombres $B$-adiques finis et pour chaque fonction classique (rationnelle, algébrique ou transcendante), nous montrons comment produire une suite ...

A New Hilbert's Hotel Argument Against Past‐Eternalism

Analytic Philosophy, Volume 67, Issue 2, Page 145-153, June 2026.
ABSTRACT This paper offers a new formulation of the “Hilbert's Hotel Argument” (HHA) which is superior to existing formulations because it (1) demonstrates that HH is logically impossible in the concrete world, (2) takes into account the need to consider the assumptions of HHA, and (3) offers a reply to an important objection concerning the validity of

3RAD‐Guided SNP Discovery for Species Identification and Conservation of the Medicinal Southern African Tree Genus Greyia Hook. & Harv.

Ecology and Evolution, Volume 16, Issue 5, May 2026.
A two‐phase SNP discovery and assay‐development strategy was used to resolve species boundaries within the tree genus Greyia, as overlapping phenotypes and distributions limit accurate identification. From 47,726 genome‐wide SNPs generated by 3RAD sequencing, a diagnostic 23‐SNP Type panel was developed and validated, successfully distinguishing G ...

Adaptive Hybrid Multi‐Objective Evolutionary Algorithm for Wireless Sensor Network Optimization: A Comprehensive Framework Integrating Opposition‐Based Learning and Levy Flight Strategies

Engineering Reports, Volume 8, Issue 5, May 2026.
The configuration of WSN design parameters presents a formidable multi‐objective optimization challenge characterized by five competing objectives that exhibit complex interdependencies. Figure 1 illustrates a typical WSN deployment topology showing sensor nodes, cluster heads, coverage areas, and various network conditions including out‐of‐range ...

Self‐Texturing Scratch‐Resistant and Bacteria‐Repellent Superhydrophobic Polypropylene Surfaces Through Extrusion‐Based Additive Manufacturing

Macromolecular Materials and Engineering, Volume 311, Issue 5, May 2026.
One‐step 3D printing combined with in‐situ self‐assembly of behenic acid creates hierarchical polypropylene surfaces with micro‐ and nanostructures. The resulting material exhibits superhydrophobicity with a contact angle of 163 (±2)°, self‐healing, and high scratch resistance, while reducing initial bacterial adhesion by 87%. ABSTRACT Superhydrophobic

A robust 3D particle tracking solver for in-flight ice accretion using arbitrary precision arithmetic

, 2019
A particle tracking code is presented to compute droplet trajectories within a known Eulerian flow field for in-flight ice accretion simulations. The implementation allows for hybrid or unstructured meshes used by common CFD solvers. A known vicinity algorithm was devised to identify particles inside the mesh by computing the intersection between the ...
