Comparison of Simple Self-Oscillating PWM Modulators

, 2016
Switch-mode power amplifiers has become the conventional choice for audio applications due to their superior efficiency and excellent audio performance. These amplifiers rely on high frequency modulation of the audio input. Conventional modulators use a fixed high frequency for modulation.

Bio‐to‐Robot Transfer of Fish Sensorimotor Dynamics via Interpretable Model

Advanced Intelligent Systems, Volume 8, Issue 3, March 2026.
This study demonstrates how a biologically interpretable model trained on real‐fish muscle activity can accurately predict the motion of a robotic fish. By linking real‐fish sensorimotor dynamics with robotic fish, the work offers a transparent, data‐efficient framework for transferring biological intelligence to bioinspired robotic systems.

Evaporative cooling by pulse width modulation (PWM) of optical dipole traps

Physical Review Research
We introduce a method for cooling atoms in an optical dipole trap using pulse-width modulation (PWM) technique, without reducing the laser power of the dipole trap. The PWM technique involves digital modulation of the trap at a fixed frequency.

High‐Fidelity Simulation‐Driven Control Framework for Robust Grid Integration of Renewable Energy Systems

Energy Science &Engineering, Volume 14, Issue 3, Page 1286-1299, March 2026.
This work proposes a high‐fidelity, simulation‐driven control framework for robust grid integration of hybrid PV–wind systems using a modular, hierarchical multi‐loop architecture with adaptive decision logic. The framework coordinates power, DC‐link voltage, and grid currents under fast load and generation changes, enabling safe exploration of extreme

Off‐Grid Solar Systems: An Experimental Work and Systematic Techno‐Economic Analysis

Energy Science &Engineering, Volume 14, Issue 3, Page 1300-1321, March 2026.
In the study mentioned above, experimental monitoring and economic evaluation of two off‐grid PV systems were conducted using a low‐cost data logger. The results suggest that basic DC systems are economically feasible compared to grid power, but that AC systems require further cost‐cutting to achieve financial viability.

Model Predictive Path‐Following Control for a Quadrotor

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT Automating drone‐assisted processes is a complex task. Many solutions rely on trajectory generation and tracking, whereas in contrast, path‐following control is a particularly promising approach, offering an intuitive and natural approach to automate tasks for drones and other vehicles.

Functional Training Mitigates Reduced Circulating Indole‐3‐Lactate Levels in Persons With Relapsing–Remitting Multiple Sclerosis

Acta Physiologica, Volume 242, Issue 3, March 2026.
ABSTRACT Aim Indoles are tryptophan (Trp)‐derived metabolites that are produced by the gut microbiota and may influence the gut‐microbiota‐brain axis in multiple sclerosis (MS). Indole‐3‐lactate (ILA) is reduced in persons with MS and improves MS clinical scores in animal models via its anti‐inflammatory remyelinating properties.
