An Integrated Engine Control Unit for a Spark Ignited Internal Combustion Engine

Engineering Reports, Volume 8, Issue 6, June 2026.
This study proposes an FPGA‐based integrated engine control unit (IECU) that combines ECU and valve control functions. It introduces a piston‐direction sensor for synchronization, supports variable timing for key‐cylinder events, enables high‐resolution virtual crank‐angle timing, and implements adaptive rule‐based control to improve real‐time engine ...

Multiobjective Optimization of Hydrogen‐Assisted Calophyllum inophyllum Biodiesel Operation in a Compression Ignition Engine

Energy Science &Engineering, Volume 14, Issue 6, Page 2897-2929, June 2026.
Tri‐fuel diesel–Calophyllum inophyllum biodiesel–hydrogen operation was tested over 96 points in a diesel engine. Eight performance and emission metrics feed a preference‐agnostic Bootstrapped Empirical Multiobjective Ranking and Selection methodology, revealing load‐blend‐hydrogen windows that increase efficiency, restrain smoke, and expose NOx trade ...

Cerebellar Transcranial Alternating Current Stimulation in the Theta Band Prevents Recall of the Initial Fear Association After Extinction Training

Human Brain Mapping, Volume 47, Issue 8, June 1, 2026.
In this 3 T fMRI study, 6 Hz cerebellar transcranial alternating current stimulation (ctACS) was applied to modulate cerebellar function during extinction training in healthy participants. ctACS applied during extinction training reduced spontaneous fear recovery during recall.

Enhancing spatial cognition through origami training: Insights from brain connectomes

Journal of Intelligent Medicine, Volume 3, Issue 2, Page 97-113, June 2026.
Origami training enhances spatial cognition via measurable brain network changes (EEG/eye‐tracking). The mental rotation and folding tasks validate these gains. This low‐cost method offers a scalable intervention for cognitive decline. Abstract Spatial cognition is a key ability of human cognition and intelligence.
