Novel initialization strategy: Optimizing conventional algorithms for global maximum power point tracking

Results in Engineering
In this research, a novel initialization strategy for conventional MPPT algorithms is proposed to define the best position for the tracking process to start over the P–V curve.

Silencing the Signal: The Metastasis Suppressor NDRG1 Disrupts Small Extracellular Vesicle‐Mediated Crosstalk in Pancreatic Cancer

Journal of Extracellular Vesicles, Volume 15, Issue 7, July 2026.
NDRG1 suppresses pancreatic cancer progression by disrupting small extracellular vesicle biogenesis, altering cargo composition, and inhibiting EV uptake by cancer cells—thereby impairing tumour–stroma communication and fibrotic activation. This study reveals NDRG1 as a novel regulator of extracellular vesicle dynamics and a promising therapeutic ...

Analysis of MPPT Failure and Development of an Augmented Nonlinear Controller for MPPT of Photovoltaic Systems under Partial Shading Conditions

Applied Sciences, 2017
The output–voltage–power curves of photovoltaic (PV) arrays exhibit complex multi-peak shapes when local shading occurs. The existing maximum power point tracking (MPPT) algorithms to solve this multi-peak problem do not consider the possibility of ...

Effects of Dual Wavelength Photobiomodulation on Osseointegration in Grafted Areas

Lasers in Surgery and Medicine, Volume 58, Issue 5, Page 429-436, July 2026.
ABSTRACT Objective This study evaluated the effects of dual‐wavelength photobiomodulation (PBMT) (infrared and red laser) on osseointegration and bone structure in areas grafted with deproteinized bovine bone (DBB). Methods Sixty‐four rats were randomly distributed into four groups. The groups were divided according to the irradiation protocol applied:

Strong Sensitivity of Simulated Biomass Burning Aerosol Transport and Radiative Effects Over the South Atlantic to Carbonaceous Aerosol Aging and Particle Density

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract Biomass burning aerosol (BBA) impacts climate through aerosol‐cloud‐radiation interactions, but models disagree on the sign and magnitude of BBA radiative effects. We quantify the sensitivity of BBA radiative effects and transport to three BBA‐relevant processes and properties: parameterized oxidative aging of organic aerosol (OA), a combined ...

Enhanced Harmony Search Algorithm for Maximum Power Point Tracking Under Partial Shading in PV Systems

IEEE Access
Multiple power peaks are introduced under nonuniform irradiation conditions in photovoltaic (PV) systems. However, conventional maximum power point tracking (MPPT) algorithms, such as the perturb-and-observe (P&O) algorithm, are only effective ...

An innovative maximum power point tracking for photovoltaic systems operating under partially shaded conditions using Grey Wolf Optimization algorithm

Automatika
Partial shading conditions (PSCs) may be unpredictable and difficult to forecast in large-scale solar photovoltaic (PV) systems. Potentially degrading the PV system's performance results from numerous peaks in the P–V curve caused by PSC.
