Elucidating the response mechanism of variation in vegetation trend to determinant is great value environmental resource management, particularly significant ecologically fragile area. The Liaohe River Basin (LRB) a key part eco-security China, which has experienced apparent climatic variations and intensified human activities recent decades. Yet, it still remains not clear about drivers shaping spatio-temporal patterns growth. Here, normalized difference index (NDVI) was utilized...
In recent years, federated GBDTs have gradually replaced traditional GBDTs, and become the focus of academic research. They are used to solve task structured data mining. Aiming at problems information leakage, insufficient model accuracy high communication cost in existing schemes horizontal this paper proposes an algorithm gradient boosting decision trees based on learning, that is, secure efficient FL for (SeFB). The uses locality sensitive hashing (LSH) build a tree by collecting similar...
Internet of Things (IoT) system provides personalized services to users by analyzing the amount data collected from billions sensors. It is important ensure trustworthiness heterogeneous IoT data. To address this requirement, provenance needs be used in system. In article, we integrate PROV-DM model into architecture and propose an model. avoid corrupting forging information, record onto blockchain. addition, use secure computable sharing illustrate that proposed can construct a graph detect...
The scalability of traditional blockchain is insufficient to meet the large-scale access requirements Source-Grid-Load-Storage, and a large number authentication data processing will bring intolerable delay business. This paper proposes sharded architecture oriented multilateral collaboration improves by using sharding technology, cross-shard transaction mechanism interaction needs multiple agents. experiment verifies that proposed can effectively improve operational efficiency in...
Provenance identification of the clastic sediments is critical for paleoenvironmental and morphological reconstruction on estuarine coast. The North Bohai Coast (NBC) receives tremendous mainly from Liaohe Daling fluvial systems. However, detailed evolution still unclear due to lack precise discrimination sediment provenance. In this study, clay mineralogy coastal in NBC was investigated determine variation fine-grained sources last century. mineral content modern riverine used model...
Short-term hydrological monitoring has limited our understanding of how climate and human activities affect flood erosion deposition. Here, we reconstruct a 1000-year-long extreme flooding record by analyzing drill cores from the Daling River estuary (NE China), NE Asia, based on observation that instrumental floods normally cause coarse particle enrichment in estuary. Our data reveal (1) centennial-scale aridification coupled with vegetation coverage reduction enhanced estuarine...
In order to achieve the effective removal of Pb 2+ from low-concentration wastewater as well lead recovery for direct reuse simultaneously, a simple electrodeposition method was used in this study. process, synthetic with low concentration 4, 8, 12 and 16 mg/L treated, more than 67% recovered PbO 2 /Ti electrode fabricated reaction tank. The test results characterizations confirmed that nanoeletrocatalyst successfully deposited on Ti substrate. Electrochemical activity tests indicated had...
Delivering only those information relevant to the needs of teammates is critical for avoiding overload. Need-driven proactive delivery has thus been widely investigated in diverse areas spanning from psychology, AI, Web-based services. CAST, a team-oriented agent architecture, realized as built-in behavior, which derived by capability anticipating others' information-needs based on computational shared mental model. However, first implementation CAST limited managing dynamic activation and...
At present, the application model and business of blockchain are still being explored. How to better integrate technology into power transaction scenario improve quality efficiency needs be further explored in combination with specific development needs. In view large scale market entities high processing capabilities large-scale high-concurrency scenario, this paper studies parallel transactions, realizes supports reading writing tens thousands entities. Research on consensus algorithm...
Effective human teams often benefit from proactivity through members' capability of anticipating different needs teammates. In this paper, we focus on three issues related to the behavior proactive information delivery. Two types are identified, intentional semantics ProInform is given, and priliminary experiments carried out study how strategies for choosing impact team performance. The work presented in paper provide a sound practical framework that enables further studies regarding
