Temporal shifts in kelp forest structure and distribution largely reflect recent ocean warming trends

Ecography, EarlyView.
Ocean warming is driving the redistribution of species at a global scale. Biogeographic transition zones are hotspots of species range shifts, as both warm‐ and cold‐adapted species are found toward contrasting range edges. While anecdotal evidence suggests some distributional shifts have occurred in the northeast Atlantic, the empirical evidence base ...

Ship Detection under Low-Visibility Weather Interference via an Ensemble Generative Adversarial Network

Journal of Marine Science and Engineering, 2023
Maritime ship detection plays a crucial role in smart ships and intelligent transportation systems. However, adverse maritime weather conditions, such as rain streak and fog, can significantly impair the performance of visual systems for maritime traffic.

Nowcasting World Trade With Machine Learning: A Three‐Step Approach

Journal of Forecasting, EarlyView.
ABSTRACT We nowcast world trade using machine learning, distinguishing between tree‐based methods (random forest and gradient boosting) and their linear‐regression‐based counterparts (macroeconomic random forest and gradient boosting—linear). While much less used in the literature, the latter are found to outperform not only the tree‐based techniques ...

On Small Satellites for Oceanography: A Survey [PDF]

, 2015
The recent explosive growth of small satellite operations driven primarily from an academic or pedagogical need, has demonstrated the viability of commercial-off-the-shelf technologies in space. They have also leveraged and shown the need for development

Beyond Gut Modulation: A Critical Review of the Therapeutic Potential, Safety, and Clinical Prospects of Natural Polysaccharides for IBD

Food Safety and Health, EarlyView.
In this review, we critically summarized the application of natural polysaccharides (NPs) for the treatment of IBD. This approach combines, in a unique way (right), the basic structure–activity relationships of NPs from different origins (left) with their multipronged mode of action, which involves modulation of the gut microbiota and other ...

Operating Capacity, Pricing and Supply Elasticity in Container Shipping Markets

International Journal of Finance &Economics, EarlyView.
ABSTRACT We investigate the channels through which changes in operating capacity influence freight rates in the container shipping market using a novel dataset to create an operating capacity index at the shipping‐route level. Our analysis reveals that when supply elasticity is low, an increase in operating capacity tends to drive freight rates upward,

Research on Ship Traffic Flow Prediction Using CNN-BIGRU and WOA With Multi-Objective Optimization

IEEE Access
Accurate understanding of maritime traffic flow is crucial for optimizing waterway and port resources. However, the complex spatiotemporal characteristics and non-stationary sequences in maritime traffic pose challenges for feature extraction. This study

Neurophysiological correlates of visually induced motion sickness severity: A scoping review of the impact of experimental settings on EEG spectral power

Journal of Intelligent Medicine, EarlyView.
This review synthesizes EEG findings from 28 VIMS studies across four inducing scenarios (abstract cues, virtual videos, vehicle driving, and game scenes) and two display types (HMD and monitor). While Delta/Theta enhancement consistently reflects sensory conflict, Alpha activity shows context dependency: predominantly increasing during passive viewing
