Resistance-interval training combined with Chlorella vulgaris supplementation modulates PCSK9, ghrelin, adropin, and MANF in obese men: a randomized controlled trial

Obesity disrupts lipid metabolism, appetite regulation, vascular function, and cellular homeostasis through interconnected pathophysiological mechanisms, increasing cardiometabolic disease risk. This randomized controlled trial examined whether 12 weeks of resistance-interval tra...

Enhanced Control of 1.5 MW DFIG Generators in MRWT Systems Using GA‐Based PI‐ST‐SMC: Comparative Assessment With ST‐SMC

ABSTRACT This paper proposes a novel genetic algorithm‐based proportional–integral super‐twisting sliding mode control (GA‐PI‐ST‐SMC) strategy for the rotor‐side converter of a 1.5 MW doubly‐fed induction generator (DFIG) operating in marine renewable wind turbine (MRWT) systems....

Optimal Frequency Control in Isolated Microgrids Integrating Renewable Energy and PHEVs Using a Modified Ziegler–Nichols-Based Multistage PID Controller

Maintaining frequency stability in islanded microgrids (MGs) has become increasingly challenging due to the growing penetration of renewable energy sources, particularly photovoltaic systems, wind turbine generators (WTGs), and plug-in hybrid electric vehicles (PHEVs). The interm...
