Augmented Harris Hawks Optimizer with Gradient-Based-Like Optimization: Inverse Design of All-Dielectric Meta-Gratings

Biomimetics, 2023
In this paper, we introduce a new hybrid optimization method for the inverse design of metasurfaces, which combines the original Harris hawks optimizer (HHO) with a gradient-based optimization method.

Nature‐Inspired Meta‐Heuristic Optimization Algorithms Integrated With Ensemble Machine Learning Techniques for Particulate Matter 2.5 Modeling

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Particulate Matter 2.5 is a major air pollutant that can deeply penetrate the respiratory system and enter the bloodstream when inhaled. The current study employs the use of both Nature inspired Meta‐heuristic optimization algorithms and Ensemble Machine learning techniques for the estimation of Particulate Matter 2.5 value using Sulfur ...

Swedish Intensive Care Physicians' Attitudes Towards Withholding or Withdrawing Life‐Sustaining Treatment in Critically Ill Children

Acta Anaesthesiologica Scandinavica, Volume 70, Issue 6, July 2026.
ABSTRACT Background Decisions to withhold or withdraw life‐sustaining treatments for critically ill children are challenging. This study aims to identify Swedish intensivists' attitudes, values and experiences towards the decision‐making process concerning withholding or withdrawal of life‐sustaining treatment in critically ill children.

The Transcription Factor DPB Confers Antiviral Defence Against Potato Virus X by Modulating MYB‐Dependent Signalling

Molecular Plant Pathology, Volume 27, Issue 7, July 2026.
This study identified that NbDPB confers resistance to potato virus X by directly activating the transcription factor NbMYB, which engages a hormone‐signalling network likely involving jasmonic acid and salicylic acid pathways. ABSTRACT As a transcriptional co‐factor of E2F, DP proteins are typically involved in the regulation of plant cell‐cycle ...

A local projection stabilised HHO method for the Oseen problem

Computers & Mathematics with Applications
In this article, we consider a local projection stabilisation for a Hybrid High-Order (HHO) approximation of the Oseen problem. We prove an existence-uniqueness result under a stronger SUPG-like norm. We improve the stability and provide error estimation in stronger norm for convection dominated Oseen problem.

Porcine kidney xenotransplantation: From primate models to clinical reality

Animal Models and Experimental Medicine, Volume 9, Issue 6, Page 1142-1166, June 2026.
In the face of a critical shortage of human donor kidneys for end‐stage renal disease patients, porcine kidney xenotransplantation has emerged as a viable solution. This field has navigated major hurdles, including immune rejection, physiological incompatibilities, potential biomechanical differences and the risk of cross‐species infection. To overcome

An effective networks intrusion detection approach based on hybrid Harris Hawks and multi-layer perceptron

Egyptian Informatics Journal
This paper proposes an Intrusion Detection System (IDS) employing the Harris Hawks Optimization algorithm (HHO) to optimize Multilayer Perceptron learning by optimizing bias and weight parameters. HHO-MLP aims to select optimal parameters in its learning

Reading hominin life history in fossil bones and teeth: methods to test hypotheses regarding its evolution

Biological Reviews, Volume 101, Issue 3, Page 1463-1478, June 2026.
ABSTRACT Human life history is derived compared to that of our closest living relatives, the great apes. It has been suggested that these derived traits are causally related to aspects of our ecology, social behaviour and cognitive abilities. However, resolving this requires that we know the evolutionary trajectory of our distinctive pattern of growth,

Homogeneous Multigrid for Hybrid Discretizations: Application to HHO Methods

Numerical Methods for Partial Differential Equations
ABSTRACTWe prove the uniform convergence of the geometric multigrid V‐cycle for hybrid high‐order (HHO) and other discontinuous skeletal methods. Our results generalize previously established results for HDG methods, and our multigrid method uses standard smoothers and local solvers that are bounded, convergent, and consistent. We use a weak version of

Performance Assessment of Spark-Ignition Engine Combined with an HHO Generator

Engineering Proceedings
This study investigates the performance of a four-stroke, spark-ignition engine equipped with a commercial HHO generator that utilizes tap water for HHO gas production. Employing adjustable voltage levels (15 V, 25 V, and 30 V), the generator’s impact on
