Training Multi-Layer Perceptron Using Harris Hawks Optimization

2020 International Congress on Human-Computer Interaction, Optimization and Robotic Applications (HORA), 2020
In this paper, Harris hawks optimization (HHO) algorithm has been proposed as an up-to-date meta-heuristic algorithm for training multi-layer perceptron (MLP). The performance of the HHO-based MLP trainer was tested by employing five standard data sets (XOR, Balloon, Iris, Breast Cancer and Heart). The results were compared with those obtained with the

Inter‐Individual Differences in T1, T2, and Proton Density Using Quantitative Synthetic Imaging for 1H‐MRS Quantification

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2489-2499, May 2026.
ABSTRACT Purpose Metabolite concentrations can be determined from proton magnetic resonance spectroscopy (1H‐MRS) data using water as an internal reference. This calculation requires tissue‐specific water T1 and T2 relaxation constants and proton density (PD).

Irrigation using slightly saline water from emerging desalination technologies as a solution to short‐term drought

PLANTS, PEOPLE, PLANET, Volume 8, Issue 3, Page 831-842, May 2026.
With global weather patterns becoming more extreme and unpredictable, sourcing reliable irrigation water is vital for improving food security and conserving drinking water in drought‐prone areas. Emerging desalination technologies, which are still in the development phase, could potentially provide large quantities of slightly saline water for ...

Integrated improved Harris hawks optimization for global and engineering optimization

Scientific Reports
AbstractThe original Harris hawks optimization (HHO) algorithm has the problems of unstable optimization effect and easy to fall into stagnation. However, most of the improved HHO algorithms can not effectively improve the ability of the algorithm to jump out of the local optimum. In this regard, an integrated improved HHO (IIHHO) algorithm is proposed.

Altered Dynamic Functional Connectivity of the Frontoparietal Network in Major Depressive Disorder: Evidence From a Large‐Scale Resting‐State fMRI Study

Brain and Behavior, Volume 16, Issue 4, April 2026.
Using resting‐state fMRI data from 887 participants, we examined the dynamic functional connectivity of the frontoparietal network in major depressive disorder. Patients showed longer dwell time and greater occupancy in hypoconnected states, with fewer transitions between connectivity patterns, indicating altered temporal organization of network ...
