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: This study aimed to investigate the natural attenuation of arsenic (As) in a river following an eruption of the Mount Iou volcano in Japan. The research found that dissolved As in the river water primarily decreased through dilution and sorption/coprecipitation with Fe, Mn, and Al (hydr)oxides. However, peaks in As concentration were observed during rainfall events, possibly due to sediment resuspension.

Summary: Understanding suspended sediment processes in the mouth-bar region during typhoons is important for estuarine geomorphic prediction. An observation system was used to explore suspended sediment dynamics during Typhoon Higos in the Modaomen Estuary. Results showed that suspended sediment concentrations during typhoons can be 30 times larger than normal conditions, primarily due to sediment resuspension induced by typhoon waves. The dynamics of suspended sediment varied depending on the dominant flows in the mouth-bar region, either being influenced by wind-driven flow and ebb surge transport combined with river flooding or tidal processes.

Summary: Strong human activities and climate change have caused significant hydrological and sediment dynamics changes in river systems globally. The study in the Yellow River basin found that sediment discharge and in-reach sediment budget have varied over the past few decades, with streamflow and sediment load decreasing before 2000 but streamflow increasing since then. Soil conservation measures and reservoirs have been key factors in reducing sediment load, with different impacts in different reaches of the river.

Summary: The Yellow River has experienced significant environmental changes due to dam regulations, affecting the downstream hydrologic regime and sediment and POC transport. This study investigated the changes in sources and transport of POC from the lower Yellow River to the river mouth under different dam operation stages. The results showed that riverbed erosion and clear water release from the reservoir contributed to enriched delta 13C POC, while muddy floodwaters and sediment released from the reservoir increased POC content. The distribution of river-laden POC at the river mouth was modulated by plume dynamics and deposition of coarse-grained sediments.

Summary: In this paper, an enhanced fractional order sliding mode control (FOSMC) method is proposed to improve the control performance of fractional order uncertain systems with multiple mis-matched disturbances. The multiple disturbances and uncertainties are estimated by finite-time disturbance observers and a fractional order extended state observer. A fractional order switching law is designed for fast convergence of system states. The proposed method incorporates feedforward compensation, the fractional order switching law, and an auxiliary state for input saturation. Numerical examples and a motor speed control problem are used to demonstrate the effectiveness of the proposed method through performance comparisons with existing control methods.

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: 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.
