Summary: Continental shelves and estuaries are important regions for the production and emission of N2O, with variations in distribution and emissions affected by temperature gradients, currents, and riverine inputs. N2O concentrations peak in spring and decrease sharply in summer and fall, with higher emissions in the ECS compared to the SYS. Sediments, especially around the Yangtze River Estuary, are identified as significant benthic N2O sources.

Summary: The study revealed that different controlling factors affect the distribution of PAHs in sediment and porewater. Higher levels of PAHs were found in shallow sediment, while in deeper sediment, PAHs were mainly present in porewater. The diffusion of PAHs in porewater was found to be closely related to the organic carbon content of the bottom sediment.

Summary: Suspended sediment fronts (SSFs) are a significant sub-mesoscale phenomenon that impact ocean hydrodynamics, fisheries, and ecology in estuaries, coasts, and continental shelf seas. Using 10-year archived Geostationary Ocean Color Imager (GOCI) data, the spatial distributions and long-term variations of SSFs over the Yangtze Bank were quantitatively analyzed. The findings reveal that SSFs mainly occur within the 50-m isobath, and their distributions are limited by depth gradients. Seasonal cycles and interannual variations in frontal activity are influenced by multiple factors, including topographic effects, tidal mixing, stratification, wind waves, and the El Niño-Southern Oscillation. These findings enhance our understanding of SSF variability and its ecological effects in the Yangtze Bank and other systems.

Summary: The spatial and temporal distributions of GDGT concentrations in suspended materials were investigated in the northern East China Sea to assess the potential use of GDGT-based TEX86 as a proxy for annual mean sea surface temperature (SST). The study found significant differences between TEX86 temperatures and in situ temperatures, indicating the limitations of using TEX86 as a proxy for SST in the study area. The presence of high GDGT concentrations near the bottom suggests sediment resuspension and transportation in the western part of the area, while maximum GDGT concentrations in the eastern part were found in the subsurface layer at depths of 20-50 m.

Summary: Modulated by complex processes, suspended sediment fronts (SSFs) on the inner shelf of the East China Sea persist and vary notably. Frontal activity is mainly confined to nearshore waters and influenced by bottom topography and tide-induced mixing. The seasonal cycle dominates the variability of SSFs, with the highest frontal probability in winter and hindrance of frontogenesis in summer. The discharge of the Yangtze River and the El Nino-Southern Oscillation also impact the variability of SSFs.

Summary: The spatial distributions, fluxes, and environmental effects of non-methane hydrocarbons (NMHCs) in the Yellow Sea and the East China Sea were investigated in spring. The study found that alkenes in surface seawater were more abundant than their saturated homologs, and the concentrations of NMHCs decreased with carbon number. Isoprene distributions were related to chlorophyll a and certain phytoplankton species, while atmospheric alkanes decreased from inshore to offshore and alkenes were mostly from oceanic sources. Isoprene was a significant contributor to ozone and secondary organic aerosol formation in the region.

Summary: This study reveals that the seasonal and spatial changes of N. scintillans in the East China Sea and southern Yellow Sea are largely controlled by phytoplankton biomass, particularly the concentration of chlorophyll-a. The abundance of N. scintillans in the Changjiang Estuary significantly increased in 2011 due to accelerated eutrophication and warming, resulting in higher phytoplankton abundance.

Summary: The study used positive matrix factorization (PMF) and a GeoDetector model to assess the sources and ecological risks of heavy metal contamination in the Yancheng Coastal Wetland. Wetland environments were found to have a strong ability to sequester heavy metals, with parent soil material, agriculture, and industrial pollutants identified as the main sources. The ecological harm of heavy metal exposure was minimal, except for Cd and Hg, which were primarily caused by vehicle emissions.

Summary: This study used variable coefficients generalized additive models to reveal the non-stationary effects of density dependence, fishing pressure, and climatic conditions on the population dynamics of Japanese sardine. The results indicated that the dynamics of Japanese sardine from 1976 to 2018 could be divided into four periods: the 1980s with high abundance sustained by suitable climatic conditions, the 1990s with population collapse due to negative density-dependent effects and degrading climatic conditions, the 2000s with restricted population increase caused by negative triple effects, particularly high fishing pressure, and the 2010s with population recovery facilitated by favorable climatic conditions and low fishing pressure.

Summary: This article reports on the high-density discovery of gray rockcod larvae in high latitudes in the Southern Ocean and reveals their early life characteristics through otolith microstructure analysis. Compared to populations in lower latitudes, the gray rockcod in the Amundsen Sea polynyas showed later hatch times, smaller hatch sizes, and faster growth rates. Therefore, it is speculated that the Amundsen Sea polynyas may be potential spawning grounds for gray rockcod.

Summary: Regular and long-term monitoring of coastal areas is crucial to mitigate the impacts of climate and human-driven hazards. In Africa, where observations are generally scarce, a network of low-cost, multi-variable shore-based video camera systems has been established to share data, methods, and results, aiming to implement an integrated coastal management policy. This network has provided new insights into the evolution of African beaches, waves, sea level impacts, and is a platform for interdisciplinary observations in resources and ecology, erosion and flooding, early warning systems, and science-based coastal infrastructure management.

Summary: This article proposes a novel four-degree-of-freedom (4-DOFs) modulation scheme for the hybrid dual active bridge (HDAB) converter, which improves efficiency by utilizing the respective structural characteristics of the half bridge and full bridge. The steady-state model of the HDAB converter with the 4-DOF modulation scheme is established, and the optimal O4-DOF modulation scheme is obtained using the particle swarm optimization (PSO) algorithm. Compared to the conventional phase shift modulation (PSM) scheme, the proposed O4-DOFs modulation scheme significantly improves converter efficiency. The theoretical analysis is verified through an experimental platform with specific input and output parameters.

Summary: Plume bulges were found in the Pearl River Estuary (PRE) during a flood-ebb tidal cycle, contrary to previous belief that estuaries with trumpet-like characteristics are less prone to form plume bulges. The formation dynamics and influences of discharge change on the plume bulge were revealed through simultaneous observations. The tidal plume was identified as the main component forming the plume bulge, rather than the surface-advected plume. Higher discharge enhanced the momentum and flux of the tidal plume, while lower discharge favored the formation of a surface-advected plume along the west bank.

Summary: This study explores the long-term variations and regime shifts of eight large marine ecosystems in the Arctic, focusing on the comparison between ecosystems in the Atlantic and Pacific sectors. The results suggest that the fish abundance in the Atlantic sector showed an increasing trend before the 1970s/1980s and decreased subsequently, while the Pacific sector showed an increasing trend before the 1990s. Most of the ecosystems were regulated by Atlantic Multi-decadal Oscillation, with exceptions in the Greenland Sea and West Bering Sea LMEs.

Summary: This study investigated the clinical role of HOTAIR in patients with carotid artery stenosis (CAS) and its mechanism in vascular smooth muscle cells (VSMCs). The results showed that HOTAIR was significantly upregulated in CAS patients and could discriminate between patients and healthy individuals. Overexpression of HOTAIR increased the viability and migration of VSMCs, while silencing HOTAIR restricted abnormal activities of VSMCs. Furthermore, a targeted relationship between HOTAIR and miR-148b-3p was confirmed, and the levels of miR-148b-3p in VSMCs were regulated by HOTAIR. Therefore, HOTAIR may serve as a diagnostic biomarker for CAS patients and play a role in regulating the activity of VSMCs.
