Summary: In this study, we derived the asymptotically tight QZZB for phase estimation considering photon loss and phase diffusion. Our results showed that coherent state (CS) always performed better than squeezed vacuum states (SMSVS and TMSVS) in the photon loss environment. Interestingly, in the phase-diffusion environment, the estimation performance of the QZZB for TMSVS can be better than that for CS over a wide range of phase-diffusion strength.

Summary: Sleep deprivation can impact performance monitoring and error monitoring abilities, with individuals demonstrating more conservative estimates of performance and impaired error monitoring following sleep loss. Studies on performance monitoring are limited by design flaws, while error-monitoring studies lack behavioral measures to directly assess error-awareness. Future research should focus on controlling confounding factors in performance monitoring and utilizing combined behavioral and ERP measures in error-monitoring studies to better understand the effects of sleep loss.

Summary: This study investigates the influence of size on the fracture characteristics of UHPFRC under flexure and tension conditions. The UHPFRC samples contained 1% twisted steel macrofibers and 1% smooth steel microfibers. The study finds that the UHPFRC exhibits a normal size effect on fracture toughness and microcrack number, with the hardening fracture toughness being higher than the complementary toughness. The length of the cohesive zone in UHPFRC is significantly greater than that in conventional concrete, and the size effect is more pronounced under tension load.

Summary: Mitigating bycatch of non-target fish species is important in fisheries management. This study analyzed Chinese tuna longline fishery data to build models for assessing bycatch rates and ratios. Results showed that the Pacific Ocean had lower bycatch rates and ratios compared to the Indian and Atlantic Oceans. Fishing in open oceans also reduced the risk of high bycatch ratios. Specific fishing grounds were recommended for different tuna species. Setting fishing gear deeper than 500m was found to lower bycatch rates and ratios.

Summary: The coasts of Senegal have abundant fishery resources due to the frequent occurrence of intense upwelling systems. Fishing is a vital activity for Senegal, playing an important role in the country's socioeconomic plans and food security. This review provides an update on the Senegalese marine fisheries from 1999 to 2018, discussing the political environment and management measures taken to protect exploited species. The study reveals the dynamic and significant contribution of the Senegalese fishing sectors to the country's economic growth. However, it also highlights increasing catches, economic value, and illegal fishing practices in the marine fisheries sector. The review identifies the main challenges faced by the fisheries sector and suggests recommendations to address them, including the application of new assessment methods suitable for data-poor fisheries.

Summary: This study analyzed the levels of PAHs in various coastal marine seafood in the Wentai fishing area and identified the sources of these PAHs. The results showed that the PAHs in the seafood were mainly derived from fossil fuel sources. The study also assessed the behavior of PAHs in the food chain and their association with dietary risk. It was found that the area had a relatively short food chain and higher trophic magnification factors. The highest carcinogenic risk was associated with consuming yellow croaker. Therefore, it is necessary to control the unintentional use of fossil fuels and optimize the energy structure in the nearby terrestrial area to reduce dietary risk.

Summary: Catch-only methods (COMs) based on catch histories are commonly used in fisheries management, but they tend to bias the estimates of stock status due to potential catch errors. This study evaluated the performance of two types of COMs, Catch-MSY and catch-only boosted regression trees, and found that both methods were influenced by catch errors and showed poor performance in correctly identifying stock biomass status. The study suggests that improving catch quality would not improve the estimation of COMs and does not recommend their application in fisheries management.

Summary: Keystone species play a crucial role in maintaining community stability and species diversity. Identifying and studying these species helps prioritize important species and enhance the understanding of community stability mechanisms. This study aimed to identify major keystone species in an important ecosystem in the East China Sea. Data from fisheries surveys conducted between 2016 and 2021 were analyzed, and Muraenesox cinereus, Leptochela gracilis, and Trichiurus lepturus were identified as keystone species based on principal component analysis. Removal analysis suggested that the loss of keystone species could negatively impact the complexity and stability of the food web in the East China Sea. Therefore, prioritizing keystone species in marine ecosystems is crucial.

Summary: In this study, acoustic survey data collected by the Songhang research vessel in 2022 were used to analyze the spatiotemporal factors and environmental influences on the sound-scattering layer (SSL) in the North Equatorial Current (NEC) warm pool region of the Central and Western Pacific Ocean. It was found that the SSL in this region is primarily distributed in shallow waters above 100 m and consists of micronekton and zooplankton with diel vertical migration behavior. Factors such as temperature, current velocity, turbidity, solar altitude angle, longitude, and latitude were identified as important in influencing the SSL distribution. The results of this study have implications for long-term studies on ecological changes and their impact on micronekton and zooplankton distribution.
