Abstract:
AbstractRiver flow in the Lower Yangtze River (LYR) is influenced by the combined effect of runoff and tides, and the complex flow conditions tend to cause sediment deposition in waterways, which in turn affects navigation conditions. In order to improve the understanding of the river mechanism of tidal reaches, this study selected a typical reach in the LYR – the Kouanzhi Waterway (KW) – as an example to investigate the flow characteristics that affect sediment transport processes. Sedimentation annually occurs at the entrance of the KW and a large sidebar constantly increases in size, causing the reduction of navigation depth and width, but the causes of the sedimentation are still unclear. In this study, a three-dimensional (3D) model of the KW was established based on the Delft3D, and the k-epsilon model was chosen to simulate the turbulent flow. The model simulates the flow processes during flood tides in flood and dry seasons. The results of the numerical simulation show that a significant difference exists in the large-scale flow structures between the flood and the dry seasons. In the flood season, flow at the entrance of the KW is extremely turbulent and a large-scale vortex shedding phenomenon is formed downstream of the channel entrance, which causes a great sediment transport rate at the entrance. In addition, because the river width widens in the middle part of the KW, a large-scale circulation flow structure is developed near the Sanyiqiao sidebar. The circulation is supposed to trap and deposit sediment on the sidebar. In the dry season, the intensity of flow turbulence is greatly reduced, which causes the sediment transport rate at the entrance decreases accordingly. In addition, the circulation flow structure at the Sanyiqiao disappeared, and thus the sidebar is supposed to be under erosion during this period. The results of this study provide a vital reference for the engineering works of waterway regulations in tidal river reaches.

AbstractAs an emerging disaster, the drought-flood abrupt alternation (DFAA) may cause unprecedented socio-economic impacts under changing environment, which has attracted extensive attention in recent decades. DFAA involves drought to flood (DTF) and flood to drought (FTD). However, thus far, little effort has been made to identify DFAA with high spatial resolution. Moreover, few studies have fully revealed the driving mechanisms of DFAA by large-scale climate factors. Here, the Yellow River Basin (YRB) was selected as the research area, which is an important agricultural base in China. The spatiotemporal characteristics of DFAA at multiple time scales during flood season were analyzed using 0.25° grid precipitation from 1961 to 2020 in the YRB. Furthermore, the Pearson correlation method and cross wavelet method were used to investigate the relationship between circulation anomaly (such as Arctic oscillation (AO), Pacific decadal oscillation (PDO), El Niño Southern Oscillation (ENSO), and sunspot) and DFAA to explore the potential causes of DFAA in this region. The results demonstrated that: (1) FTD trend in the YRB is serious, and the short period of FTD trend is June-July &gt; July-August &gt; August-September; (2) spatially, the high-frequency long-period DFAA was distributed in the whole YRB, while the DFAA in June-July and July-August were concentrated in the center of the YRB; (3) AO and PDO are the key factors to induce DFAA in the YRB, especially the changes of AO and PDO phase. This study helps improve our understanding of the relationship between DFAA and large-scale climate factors and provides new insights for future disaster assessment.

Abstract:
This chapter presents data supporting the hypothesis that glutamate neuroreceptor peptides are specific biomarkers of diffuse axonal injury (DAI) and compromised cerebral blood flow following neurotrauma. Specifically, the authors propose that three key brain biomarkers might be utilized to improve diagnostic certainty of the consequences of acute neurotrauma: α‎-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA), N-methyl-D-aspartate (NMDA), and kainate receptor peptides. AMPA receptor peptides are associated with subcortical DAI, while NMDA and kainate receptors peptides predominantly reflect arterial and venous circulations in cortical and brainstem areas, respectively. Feasibility studies of these biomarkers in the blood of patients with neurotrauma are presented in conjunction with neuroimaging and Glasgow Coma Scale (GCS) scores.

Abstract:
Aiming at the problems of incomplete semantic understanding and insufficient word position information in complex Chinese word segmentation, a large-scale multilingual database Chinese word segmentation method based on hybrid deep learning technology is proposed. In this scheme, the bidirectional context information is effectively used through the bidirectional threshold circulation unit, and the long-distance dependency information is effectively modeled by the BiLSTM model. At the same time, the dependency between the output tags can be considered through the CRF layer. Then a double byte query method is proposed to expand the CRF model, and the whole process is realized by machine learning and training. The simulation results show that the hybrid model makes full use of the advantages that BiLSTM can extract local information by using long-distance information and CNN, and it can complete the task of Chinese word segmentation more efficiently and accurately. Under the same experimental conditions, the performance is improved by about 30% compared with similar methods.

Abstract:
With the rapid advancement, nanoparticles (NPs) based drug delivery systems have been recognized as expedient over traditional therapeutics for breast cancer, fostering targeted drug release, long circulation time, reduced toxicity, and greater bioavailability. Under normal circumstances when this exogenous structure of nano-scale dimension approaches nearby cells, it evokes early tripping leading to membrane wrapping and NPs cellular uptake. Tailoring NPs structure for safe and intended entry into cells is at the core of nano-therapeutics for attaining high-yield prognostic and therapeutic efficacy. Interestingly NPs uptake is crucial as it unravels pathway selection and is decisive for the intracellular fate of nano-medicine. Over the past, it remained a major challenge to target specifically to improve their delivery. A significant effort has been devoted to understanding the endocytosis of nano-medicine for efficient intracellular delivery of NPs. Here we present an overview of the different endocytic pathways used by cells. Novel strategies in NPs design to exploit the uptake mechanisms to decipher intended uptake and target breast cancer. Current advances and strategies are deployed to breach these barriers and attain the ultimate vision of nano-carriers in diagnostics and therapeutics.

&lt;i&gt;Abstract&lt;/i&gt;.—Zooplankton communities perform a critical role as secondary producers in marine ecosystems. They are vulnerable to climate-induced changes in the marine environment, including temperature, stratification, and circulation, but the effects of these changes are difficult to discern without sustained ocean monitoring. The physical, chemical, and biological environment of the Gulf of Maine, including Georges Bank, is strongly influenced by inflow from the Scotian Shelf and through the Northeast Channel, and thus observations both in the Gulf of Maine and in upstream regions are necessary to understand plankton variability and change in the Gulf of Maine. Large-scale, quasi synoptic plankton surveys have been performed in the Gulf of Maine since Bigelow’s work at the beginning of the 20th century. More recently, ongoing plankton monitoring efforts include Continuous Plankton Recorder sampling in the Gulf of Maine and on the Scotian Shelf, U.S. National Marine Fisheries Service’s MARMAP (Marine Resources Monitoring, Assessment, and Prediction) and EcoMon (Ecosystem Monitoring) programs sampling the northeast U.S. Continental Shelf, including the Gulf of Maine, and Fisheries and Oceans Canada’s Atlantic Zone Monitoring Program on the Scotian Shelf and in the eastern Gulf of Maine. Here, we review and compare past and ongoing zooplankton monitoring programs in the Gulf of Maine region, including Georges Bank and the western Scotian Shelf, to facilitate retrospective analysis and broadscale synthesis of zooplankton dynamics in the Gulf of Maine. Additional sustained sampling at greater-than-monthly frequency at selected sites in the Gulf of Maine would be necessary to detect changes in phenology (i.e. seasonal timing of biological events). Sustained zooplankton sampling in critical nearshore fish habitats and in key feeding areas for upper trophic level organisms, such as marine mammals and seabirds, would yield significant insights into their dynamics. The ecosystem dynamics of the Gulf of Maine are strongly influenced by large-scale forcing and variability in upstream inflow. Improved coordination of sampling and data analysis among monitoring programs, effective data management, and use of multiple modeling approaches will all enhance the mechanistic understanding of the structure and function of the Gulf of Maine pelagic ecosystem.

Based on the limitations of the site environment, the large heat exchange area of the air cooler, and the high cost of equipment construction for the air-cooled waste heat removal scheme of a small reactor, this paper studies the water-cooled passive residual heat removal scheme and analyzes the water-cooled wate

Abstract Due to the low permeability of geothermal reservoirs, hydraulic fracturing could provide conductive pathways to improve fluid flow and heat exchange. Fractures in geothermal systems not only provide channels for fluid flow, but also provide a larger contact area for heat transfer to achieve an efficient and economic heat extraction. Since commercially available proppants have low thermal conductivity, we present a method to improve heat exchange inside propped fractures by increasing thermal conductivity of the proppant packs using conductive coating. Accurate numerical modeling requi

Abstract:
In typical pressurized water reactor (PWR), to cope with beyond design basis events such as station black out (SBO) or small break loss of coolant accident with safety injection system failure, injection from accumulator sustains core cooling by compensating for loss of coolant. Core cooling is sustained by single- or two-phase natural circulation or reflux condensation depending on primary coolant mass inventory. Behavior of the natural circulation in PWR has been investigated in the facilities such as Large Scale Test Facility (LSTF) which is a full-height and full-pressure and thermal-hydra

Abstract:
Budikdamber is the acronym for “budidaya ikan dalam ember”, an Indonesian term for a small-scale aquaponic system in a plastic bucket. This equipment is famous for its compact size and easy implementation to cultivate fish in households, especially for those with limited space resources. Budikdamber can be seen as the proper solution to support one of Kulon Progo’s critical programs to reduce its poverty rate. The number of animal protein intake in each local community family is one indicator to measure the poverty rate. Hence, Budikdamber allows lower-income families to cultivate fish in thei

Abstract:
The accuracy of the Copernicus Marine Environment and Monitoring Service (CMEMS) ocean analysis and forecasts highly depend on the availability and quality of observations to be assimilated. In situ observations are complementary to satellite observations that are restricted to the ocean surface. Higher resolution model forecasts are required by users of the CMEMS global and regional ocean analysis and forecasts. To support this with an efficient observational constrain of the model forecast via data assimilation, an increase observation coverage is needed, associated with an improved usage of

Abstract:
The purpose of this publication is to summarize the state of knowledge on the effects of environmental variability and climate change for individual species and stocks based on literature review, giving species-climate information for 32 key taxa in Swedish marine and coastal waters. The report is written in English. The extent and scale of recent changes in climate due to global warming is unprecedented and causes increasing effects on ecosystems. In oceans, ongoing warming leads to, for example, increased water temperatures, decreased ice cover and effects on hydrology and water circulation
