Abstract	Multi-layer networks which consist of high-frequency cells and low-frequency cells in the same coverage area, can ensure capacity and coverage simultaneously. However, the existing handover algorithms in multi-layer networks result in the waste of spectrum resources. In this paper, we propose a new handover algorithm to address this gap. To ensure coverage and capacity, the proposed algorithm utilizes inter-frequency handover based on coverage and user throughput, encourages inter-frequency handover but suppresses intra-frequency handover. We provide a theoretical basis for this algorithm, whose superior performance has been verified by our simulations. Compared with the traditional algorithms, the proposed algorithm balances the load ratio between high-frequency cells and low-frequency cells from 30/90 to 60/80; Meanwhile, the proposed algorithm increases user throughput by at least 54.3% for the handover users; Moreover, the proposed algorithm increases the average signal interference plus noise ratio by about 1.5 dB for the high-frequency cells and 5 dB for the low-frequency cells, which gives rise to the increase in system capacity for 10.5% and 11.57% for downlink and uplink, respectively; Besides, the proposed algorithm decreases call blocking ratio by 38% and end-to-end delay by 5.82%.

Abstract	Microplastics (MPs) pollution in sediments brings a huge challenge to the sustainable development of society. China is one of the countries with the largest production and application of plastic products in the world. The sustainable management of MPs pollution in sediments from China has important implications for achieving the United Nations Sustainable Development Goals. There is a lack of targeted management measures for the sustainable management of MPs pollution in sediments from China. In this study, 74 study areas were collected to analyze the pollution status of MPs in sediments from China. The results showed that the study on MPs pollution in sediments from China was concentrated in the Bohai Rim Economic Circle (n = 12), the Yangtze River Delta Economic Circle (n = 16) and the Pearl River Delta Economic Circle (n = 13). And the average abundance of MPs in sediments from China showed a decreasing trend from coastal to inland. Fiber had the highest centrality degree in the correlation network of MPs types. The reduction of fiber in sediments can reduce the diversity of MPs in sediments from China. Population density, economic level, urbanization level and industrial structure were significantly correlated with MPs types in sediments from China. The targeted management measures can be formulated based on the contribution of different human activities to MPs types. Managing pollution sources and cutting off transmission pathways are effective means for the targeted management of MPs in sediments. In addition, legislation can effectively restrict the application of plastic products. Promulgating relevant laws and implementing targeted management are conducive to the sustainable management of MPs pollution in sediments from China. In future studies, a big data platform for MPs pollution should be established to obtain a comprehensive understanding in the pollution status of MPs in sediments from China.

Abstract	The occurrence of microplastics (MPs) pollution in sediments has brought huge challenges to the development of society. Pollution control of MPs in sediments has become an inevitable requirement for current society. This requires implementing targeted pollution control measures in high MPs ecological risk areas and controls MPs discharge in pollution source. Existing studies lack in-depth understanding in MPs ecological risk assessment and MPs pollution source analysis, this limits the pollution control of MPs in sediments. In this study, the studies of MPs pollution in sediments from 2013 to 2022 were reviewed. The results showed that the environmental problems caused by MPs pollution in marine sediments have been widely discussed over the past decade. And the occurrence of MPs pollution in sediments brought potential threat to marine ecology and human food supply. Furthermore, pollution load index, polymer risk index and potential ecological risk index of MPs were frequently used in the existing ecological risk assessment of MPs in sediments. A large amount of monitoring data and simulation data is conducive to improving these MPs ecological risk assessment indicators. This can provide a useful reference for managers to formulate MPs pollution control measures. And MPs types and land-use types can provide basis to analyze the pollution source of MPs in sediments. Developing more accurate MPs detection and analysis technologies can further improve current MPs pollution source analysis system. This is conducive to control the discharge of MPs in the pollution source. In future studies, more complete MPs ecological risk assessment system and MPs pollution source analysis system should be established to control the pollution of MPs in sediments.

Abstract	Biomedical information graphs are crucial for interaction discovering of biomedical information in modern age, such as identification of multifarious molecular interactions and drug discovery, which attracts increasing interests in biomedicine, bioinformatics, and human healthcare communities. Nowadays, more and more graph neural networks have been proposed to learn the entities of biomedical information and precisely reveal biomedical molecule interactions with state-of-the-art results. These methods remedy the fading of features from a far distance but suffer from remedying such problem at the expensive cost of redundant memory and time. In our paper, we propose a novel Residual Message Graph Convolution Network (ResMGCN) for fast and precise biomedical interaction prediction in a different idea. Specifically, instead of enhancing the message from far nodes, ResMGCN aggregates lower-order information with the next round higher information to guide the node update to obtain a more meaningful node representation. ResMGCN is able to perceive and preserve various messages from the previous layer and high-order information in the current layer with least memory and time cost to obtain informative representations of biomedical entities. We conduct experiments on four biomedical interaction network datasets, including protein-protein, drug-drug, drug-target, and gene-disease interactions, which demonstrates that ResMGCN outperforms previous state-of-the-art models while achieving superb effectiveness on both storage and time.

Abstract	Image-to-image translation (I2I) is defined as a computer vision task where the aim is to transfer images in a source domain to a target domain with minimal loss or alteration of the content representations. Major progress has been made since I2I was proposed with the invention of a variety of revolutionary generative models. Among them, GAN-based models perform exceptionally well as they are mostly tailor-made for specific domains or tasks. However, few works proposed a tailor-made method for the artistic domain. In this project, I propose the Semantic-aware Mask CycleGAN (SMCycleGAN) architecture which can translate artistic portraits to photo-realistic visualizations. This model can generate realistic human portraits by feeding the discriminators semantically masked fake samples, thus enforcing them to make discriminative decisions with partial information so that the generators can be optimized to synthesize more realistic human portraits instead of increasing the similarity of other irrelevant components, such as the background. Experiments have shown that the SMCycleGAN generate images with significantly increased realism and minimal loss of content representations.

Abstract	Background: The evidence on the role of retroperitoneal lymphadenectomy is limited to less common histology subtypes of epithelial advanced ovarian cancer. Methods: This retrospective cohort study utilized data from the Surveillance, Epidemiology, and End Results Program from January 1, 2010, to December 31, 2019. Patients with stage III-IV epithelial ovarian cancer were included and divided into two groups based on whether they received retroperitoneal lymphadenectomy. The primary outcomes are overall survival (OS) and cause-specific survival (CSS). Results: Among the 10 184 included patients, 5472 patients underwent debulking surgery with retroperitoneal lymphadenectomy, while 4712 patients only underwent debulking surgery. No differences were found in the baseline information between the two groups after propensity score matching. Retroperitoneal lymphadenectomy during debulking surgery was associated with improved 5-year OS (43.41% vs. 37.49%, p < 0.001) and 5-year CSS (46.43% vs. 41.79%, p < 0.001). Subgroup analysis further validate the retroperitoneal lymphadenectomy increased the 5-year OS and CSS in patients with high-grade serous cancer. Although the results were not validated in the less common ovarian cancer (including endometrial cancer, mucinous cancer, low-grade serous cancer, and clear cell cancer), the tendency showed patients with the above four subtypes may benefit from the lymphadenectomy which is restricted for small sample size after propensity score matching. Conclusions: This study revealed that retroperitoneal lymphadenectomy could further improve the survival outcome during debulking surgery in patients with advanced epithelial ovarian cancer. The conclusion was affected by the histology subtypes of ovarian cancer and further studies are needed to validate the conclusion in less common ovarian cancer.

Abstract	The consumption and production of antibiotics in China rank highest in the world. As such, the occurrence of antibiotics in environmental media of China has raised significant concerns. Rivers play an important role in the sustainable development of China's economy and society, possibly causing high levels and detection frequencies of antibiotics in the aquatic environment of rivers in China. Therefore, it is necessary to understand the distribution and risk level of antibiotics in rivers. From south to north, China has seven major rivers vertically and horizontally. They are Yangtze River, Yellow River, Hai River, Liao River, Huai River, Songhua River and Pearl River. In this review, we made an extensive literature survey and published all studies on antibiotic concentrations in seven river systems of China from 2010 to 2020 were sorted out to provide a clear draw of the distribution characteristics of antibiotics. We found that 70 antibiotics have been detected in the seven major river systems. 13 typical antibiotics in surface waters of seven river systems were systematically reviewed and ecological risk assessment was conducted. The occurrence frequencies of high-risk antibiotics in surface waters followed the rank order: ETM-H

Abstract	The selective clearance of unwanted, damaged or dangerous components by macroautophagy/autophagy is critical for maintaining cellular homeostasis in organisms from yeast to humans. In recent years, significant progress has been made in understanding how phagophores selectively sequester specific cargo. Nevertheless, a fundamental question remains: Can distinct selective autophagy programs simultaneously operate within the same cell? A recent study from the Baehrecke lab has unveiled a developmentally programmed Pink1-dependent reticulophagy process in the Drosophila intestine. Furthermore, this study demonstrated that autophagy differentially clears mitochondria and ER in the same cell under the regulation of Pink1 through different E3 ubiquitin ligases, highlighting the need for further exploration in understanding the complexity of autophagic substrate selection and crosstalk between diverse autophagy programs.
