The bi-global attractor of 2D autonomous g-Navier-Stokes equation with nonlinear dampness(含非线性阻尼的二维自治g-Navier-Stokes方程解的双全局吸引子)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2023
以研究二维自治g-Navier-Stokes方程解的全局渐近性为目的,用算子分解方法证明了在有界区域上含非线性阻尼的二维自治g-Navier-Stokes方程解的双全局吸引子存在性,并估计了其Hausdorff 维数和Fractal维数。结果表明,该方程解的双全局吸引子存在且具有有限的Hausdorff 维数和有限的分形维数。

The threshold secret sharing scheme based on hyperspace parameter curve(基于多维空间参数曲线的门限秘密共享方案)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2014
引入了多维空间参数曲线的概念,提出了有限域Fp上参数曲线在实数域R上可微的思想,并给出了参数曲线上整数点的超法面方程.利用多维空间参数曲线与超法面的交点来构建参与者共享的主密钥,设计出一个直观的、安全完备的(s,n)门限秘密共享方案.结果表明,此方案在几何法中具有主密钥的单参数表示的特点,较Blakley门限秘密共享方案更具体实用,且易于实现.

Comprehensive framework for assessing and optimizing existing research networks

open access: yesConservation Biology, EarlyView.
Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

Emerging applications of large language models in ecology and conservation science

open access: yesConservation Biology, EarlyView.
Abstract Large language models (LLMs) mark a major development in artificial intelligence, with potentially transformative implications for ecology and conservation science. Built on advanced deep‐learning architectures, these models can support a wide range of tasks. We reviewed emerging applications of LLMs, drawing on the wider scientific literature

Comparative species distribution model framework for marine conservation and its application to loggerhead turtles in the Mediterranean

open access: yesConservation Biology, EarlyView.
Abstract Modeling species distributions in dynamic pelagic environments remains challenging, particularly for wide‐ranging and highly mobile species when there is limited guidance on model performance. This limitation constrains the effective use of species distribution models (SDMs) in marine conservation, where robust and transferable predictions are

A methodological assessment and reflection on member checking as a form of participant validation for conservation social science

open access: yesConservation Biology, EarlyView.
Abstract Qualitative approaches are increasingly applied in conservation social science, yet methodological reflection remains limited. Member checking, a process of returning findings to participants for feedback, is widely recognized outside conservation as a means to enhance rigor and reciprocity, but it is rarely reported in conservation research ...

Intact coastal nursery rearing amid climate‐driven phenological shifts in threatened salmon

open access: yesConservation Biology, EarlyView.
Abstract Literature linking phenology to climate has proliferated in recent decades and shows that climate change has reorganized seasonal opportunities worldwide. However, this literature often quantifies changes in point measures of timing (e.g., beginnings and peaks) without context about duration (e.g., rearing season length) or performance (e.g ...

A Review and Critique of Methods and Knowledge Gaps in Quantifying Spillover Effects from Protected Areas

open access: yesConservation Biology, EarlyView.
Abstract The sustainability of area‐based conservation initiatives depends on their value to society. Conservation often focuses inside protected areas, but the impacts of protected areas beyond their boundaries (spillovers) are critical for their social license.
