    Photogrammetric determination of movement speed of invasive Indo-Pacific lionfish in the Florida Keys by Neal Kolonay, Cassandra N. Glaspie

    Published 2025-01-01
    “…As a key determinant of how efficiently lionfish (Pterois sp.) locate and capture prey, swimming speed plays a crucial role in shaping the predator-prey interactions and broader ecological dynamics within the invaded ecosystems. Swimming speed on a small temporal and spatial scale is difficult to measure because of the need for precise measurements of both distance and duration of the behavior. …”

    Research Progress in and Planning Strategies for Multi-scale Measurement of the Efficiency of Urban Blue-Green Infrastructure in Carbon Sink Enhancement and Emission Reduction by Song LIU, Zhaocheng BAI, Dizi LIU, Peiyu SHEN

    Published 2025-01-01
    “…These strategies include: 1) At the site scale, for carbon sequestration and sink enhancement – carbon sink at the source, land balance, and ecological design; for emission reduction – symbiosis with buildings and integration into daily life. 2) At the community scale, for carbon sequestration – overall balance of revenue and expenditure, precise positioning, and proper interconnection of the carbon chain; for emission reduction – incorporation of cool islands and co-construction. 3) At the urban area scale, for carbon sequestration – enhancement of ecological space management and establishment of a carbon-safe pattern; for emission reduction – demand-based layout and organic dispersion. …”

    Bytecode-based approach for Ethereum smart contract classification by Dan LIN, Kaixin LIN, Jiajing WU, Zibin ZHENG

    Published 2022-10-01
    “…In recent years, blockchain technology has been widely used and concerned in many fields, including finance, medical care and government affairs.However, due to the immutability of smart contracts and the particularity of the operating environment, various security issues occur frequently.On the one hand, the code security problems of contract developers when writing contracts, on the other hand, there are many high-risk smart contracts in Ethereum, and ordinary users are easily attracted by the high returns provided by high-risk contracts, but they have no way to know the risks of the contracts.However, the research on smart contract security mainly focuses on code security, and there is relatively little research on the identification of contract functions.If the smart contract function can be accurately classified, it will help people better understand the behavior of smart contracts, while ensuring the ecological security of smart contracts and reducing or recovering user losses.Existing smart contract classification methods often rely on the analysis of the source code of smart contracts, but contracts released on Ethereum only mandate the deployment of bytecode, and only a very small number of contracts publish their source code.Therefore, an Ethereum smart contract classification method based on bytecode was proposed.Collect the Ethereum smart contract bytecode and the corresponding category label, and then extract the opcode frequency characteristics and control flow graph characteristics.The characteristic importance is analyzed experimentally to obtain the appropriate graph vector dimension and optimal classification model, and finally the multi-classification task of smart contract in five categories of exchange, finance, gambling, game and high risk is experimentally verified, and the F1 score of the XGBoost classifier reaches 0.913 8.Experimental results show that the algorithm can better complete the classification task of Ethereum smart contracts, and can be applied to the prediction of smart contract categories in reality.…”

    Research Progress of Methods of Initial Water Rights Allocation in River Basins by WU Dan, LIU Mengyao

    Published 2022-01-01
    “…The development of a robust and highly feasible method of initial water rights allocation in a river basin can provide important support for promoting high-quality economic development of the river basin and optimizing the layout of its industrial structure.This paper systematically reviews the methods of initial water rights allocation in river basins from four aspects:multi-objective coupling allocation methods,multi-stage coupling allocation methods with stakeholder participation,allocation methods oriented towards industrial structure optimization,and adaptive allocation methods.The results show that multi-objective coupling allocation methods focus on the coordinated reflection of multi-dimensional objectives,such as social equity,economic benefits,ecological protection,and risk control.The multi-stage coupling allocation methods with stakeholder participation concentrate on strengthening the interest interaction among water resource stakeholders and fully reflecting their interest demands.The allocation methods oriented towards industrial structure optimization center on promoting the optimization and upgrading of the industrial structures in river basins.The adaptive allocation methods highlight the improvement of the adaptability of the water resources in river basins to economic and social development.Initial water rights allocation in river basins has gradually developed from "multi-objective coupling allocation methods based on allocation principles" to "adaptive allocation methods based on allocation principles and the negotiation game mechanism".Solving the problem of adapting initial water rights to industrial structure optimization and promoting the optimization and upgrading of industrial structures and high-quality economic development will become the main lines of research on initial water rights allocation in river basins in the future.…”
