Summary: Coastal tidal flats are important ecosystems, but they are highly vulnerable to tidal dynamics, sea-level rise, and human activities. This study examined the hydrodynamics, sediment transport, and morphological changes on two tidal flats in the Yellow River Delta with different tidal regimes. The results showed that longer inundation periods under diurnal tides led to more sediment deposition, while semi-diurnal tides resulted in increased wave impact and tidal flat erosion due to lower water depths. These findings highlight the joint role of tidal regime and powerful waves in controlling sediment availability and tidal flat evolution. This has implications for managing erosion and restoring vegetation in the Yellow River Delta.

Summary: The transportation of suspended sediment in estuaries has a significant impact on erosion, deposition, landform patterns, primary productivity, and ecosystem regulation. Studying the surface suspended sediment concentration (SSC) in estuaries and adjacent waters is valuable for coastal construction and environmental monitoring. This study analyzed Landsat satellite images from 1984 to 2021 to examine the SSC in the surface layer of the Yellow River Estuary. The results showed a decline of over 30% in SSC from 1984 to 2021, with the Xiaolangdi Dam and Water and Sediment Regulation Scheme having a significant influence.

Summary: Reclamation of tidal flats is a common method used in coastal areas to expand land area and develop the economy. This study investigates the impacts of reclamation on tidal and suspended sediment dynamics using numerical modeling in the Oufei tidal flat at the Wenzhou coast. The results show that reclamation reduces the tidal flat area, weakens tidal currents, and reduces suspended sediment concentration. The construction of the Oufei dike also alters sediment circulation and enhances landward sediment transport inside the estuary. The findings of this study can be used as a reference for analyzing suspended sediment transport in other sites affected by tidal flat reclamation.

Summary: The study aims to find an effective method for monitoring suspended sediment transport in rivers. The currently used methods are not accurate enough, so the researchers tested an integrated surrogate method based on turbidity registration to determine the suspended sediment yield in the lower reach of the Danube River. The results of the tests show that the method has great potential, but further measurements are needed to refine the relationships.

Summary: In winter, freshwater and sediments are transported from the Yellow River mouth downstream into Laizhou Bay under the northeasterly wind. The transport shows convergence in the river mouth, divergence in the downstream area, and convergence in the north of Laizhou Bay. Tides and waves are the main factors affecting the transport, with tidal forcing enhancing downstream transport and wave forcing having little effect. Tidal and wave-induced bottom shear stress control sediment resuspension, with tidal mixing strengthening the upward diffusion of suspended sediments.

Summary: This study compared the sex differences of residual somatic symptoms (RSS) in patients with first-episode depression (FED). The results showed that RSS is common in FED patients, with females more likely to experience stomach pain and males more likely to experience trouble sleeping. Additionally, quality of life plays an essential role in RSS in both genders. Therefore, sex differences should be considered when assessing the relationship between RSS and therapeutic effect in depression.

Summary: A glycyrrhetinic acid-modified carboxymethyl chitosan-thioketal-rhein (GCTR) conjugate was synthesized for the in vivo delivery of celastrol. Celastrol was encapsulated into polymeric micelles formed by GCTR conjugates self-assembly in water, resulting in celastrol/GCTR PMs with high drug loading capacity and small particle size. Celastrol/GCTR PMs exhibited sustained-release in the blood environment and rapid-release in the tumor microenvironment, showing significant proliferation inhibitory effect on HepG2 and BEL-7402 cells and negligible impact on L-02 cells at low concentrations. The reactive oxygen species (ROS)-responsive properties of celastrol/GCTR PMs improved the bioavailability of celastrol and showed remarkable hepatoma-targeting properties. Celastrol/GCTR PMs effectively inhibited tumor growth with no apparent damage to different organs.

Summary: ICRF heating and NBI can synergistically accelerate beam ions and generate fusion neutrons. The synergy improves plasma performance and increases parameters such as poloidal beta, plasma stored energy, core ion temperature, neutron yield, and kinetic pressure. Various parameter scans show that decreasing minority ion concentration or the distance between resonance and magnetic axis, as well as increasing ICRF heating power or NBI beam energy can enhance the synergetic effects and result in higher energy fast ions.

Summary: Curvature variations in tidal flats have a strong influence on sediment dynamics in macro-tidal turbid bays. This study used a validated 3D sediment model to investigate the interactions between tidal flats and sediment dynamics in Hangzhou Bay. The results showed that the geometry of the tidal flats greatly affects hydrodynamics and sediment transport processes. Tidal flat reclamation alters the curvature of tidal channels and subsequently influences the circulation and sediment transport. The study highlights the importance of anthropogenic activities in shaping the geomorphological evolution of estuaries.

Summary: In response to the accuracy deterioration of SRF-PLL caused by non-ideal grid conditions and limitations of LADRC-PLL, this paper proposes an enhanced three-phase PLL that combines IMAF and LADRC. Through the use of LESO and IMAF in a specific control structure, the proposed IMAF-LADRC-PLL achieves satisfactory steady-state accuracy without compromising dynamic performance. Experimental results show that the proposed IMAF-LADRC-PLL outperforms traditional strategies in terms of dynamic performance and maintaining phase-locked accuracy.
