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

open access: yesAutomatika
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.

A novel approach to estimate non‐algal particle absorption for improved retrieval of pigment concentrations in coastal waters

open access: yesLimnology and Oceanography: Methods, Volume 24, Issue 10, October 2026.
Abstract Phytoplankton play a central role in ocean biogeochemistry and understanding their composition and variability is critical for monitoring marine ecosystem dynamics. Continuous spectrophotometric measurements (using a Seabird Sci. AC‐S) along ship tracks enable high‐resolution measurements of particle spectral absorption (apλ), and beam ...

Sex‐Specific Atlantic Salmon Upstream Passage and Fallback at a Natural Cascade After Dam Removal

open access: yesFisheries Management and Ecology, Volume 33, Issue 5, Page 963-976, October 2026.
ABSTRACT In the Boquet River (NY, USA) a low‐head dam set above a ~200‐m bedrock cascade was removed in 2015. We used radio‐telemetry to assess landlocked Atlantic salmon passage at the remaining cascade (2020, 2022). Across years, 52% of males (13/25) attempted cascade passage whereas females made no discernable attempts (0/11).

Phytoplankton Size Structure Controls the Bio‐Optical Anomaly of Antarctic Waters

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Phytoplankton in the Southern Ocean strongly influence global biogeochemical cycles, but the region's remoteness limits in situ monitoring. Satellite ocean color enables synoptic monitoring of phytoplankton dynamics by retrieving chlorophyll‐a concentration (Chl‐a).

Boosting Efficiency and Stability of Air‐Processed Blade‐Coated All‐Polymer Organic Solar Cells Based: The Role of Electron Transport Layer and Additives

open access: yesSolar RRL, Volume 10, Issue 17, 15 September 2026.
All‐polymer PM6:PY‐IT solar cells processed by blade coating in air using o‐xylene are studied alongside a PM6:Y12 binary reference and an advanced ternary PM6:Y12:PY‐IT system. We examine electron transport layers and additives to tune morphology, charge transport, and device efficiency. Characterization includes J–V, GIWAXS, AFM, and SCLC.
