Evaluating and Advancing the Use of Shore‐Based Observers for Scientific Sampling and Catch Verification in High‐Volume Fisheries

Fisheries Management and Ecology, EarlyView.
ABSTRACT Shore‐based observers are increasingly being used in place of at‐sea observers to monitor and sample commercial fisheries catch. However, few evaluations assess whether these programs meet their stated goals or how to optimize them, and industry data are rarely tested for accuracy despite serving as the foundation for catch accounting. Using a

Terrestrial Analogs to Titan for Geophysical Research

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

A novel hybrid method based MPP tracking design using boost converter for solar power systems [PDF]

The convergence time is one of the key parameters for evaluating the energy conversion efficiency of PV power systems in the experimental process of tracking the maximum power point (MPP) in real-time. When the PV system is partially shaded, for example,

Cationic Lattice Coupling Enables Efficient FAPbI3 Perovskite Solar Cells

Small Structures, Volume 7, Issue 4, April 2026.
TPPI with a rigid, asymmetric phosphonium framework orient stably at the grain boundaries and interfaces of PSCs. It polarizes FA+, reinforces hydrogen bonds, restricts FA+ rotation to stabilize the α‐phase, and enhances cation–lattice coupling to form large polarons for defect screening, thereby boosting the power conversion efficiency (PCE) and ...

Enhanced Maximum Power Point Tracking Using Modified PSO Hybrid With MPC Under Partial Shading Conditions

IEEE Access
Conventional methodologies such as Incremental Conductance (IC) and Perturbation and Observation (P&O) can be considered effective and low-cost solutions for PV Maximum Power Point Tracking (MPPT) problems in most cases.

The Met Office HadGEM3-ES chemistry–climate model: evaluation of stratospheric dynamics and its impact on ozone [PDF]

, 2016
Free-running and nudged versions of a Met Office chemistry–climate model are evaluated and used to investigate the impact of dynamics versus transport and chemistry within the model on the simulated evolution of stratospheric ozone.

Using Machine Learning to Uncover Ecological Mechanisms Controlling Abundance of Phytoplankton Size Classes From Large‐Scale Observations

Global Biogeochemical Cycles, Volume 40, Issue 4, April 2026.
Abstract Phytoplankton size classes (PSCs) and Phytoplankton functional types (PFTs) determine many fundamental biogeochemical processes including nutrient uptake, energy transfer through marine food webs, ocean carbon export, and gas exchange with the atmosphere. Discerning the causes of spatio‐temporal variability of PSCs is a scientific priority for

GABA receptor modulation of arcuate kisspeptin neuron bursting and synchronization activity in female mice

Journal of Neuroendocrinology, Volume 38, Issue 4, April 2026.
Abstract The arcuate nucleus kisspeptin (ARNKISS) neurons intermittently synchronize their activity to operate as the GnRH pulse generator and drive pulsatile reproductive hormone secretion in mammals. Although ARNKISS neurons are known to receive various GABAergic inputs, the effects of GABAA and GABAB receptor modulation on their ability to ...
