On Japanese Legal Protection on Product Configuration and Relevant Reference [PDF]
, 2016 商品形态可以理解为以商品形状为基础，结合商品图案或颜色所形成的整体外观。商品形态的保护可以分为两个层次：作为商业标识时应受到免于混淆的保护；作为智力成果时对于酷似性模仿商品的交易行为的规制。商品形态的模仿，也就可以分为混淆商品来源的模仿与不正当利用他人智力成果的模仿。这两种模仿行为本质上都是利用他人商业成就而未付出实质性努力的行为，即俗称“搭便车”的不正当竞争行为。我国现行法律没有明确“商品形态”的法律概念，对于商品形态的前述两个层次的保护是不完善的。本文将在介绍日本《不正竞争防止法 ...

Comprehensive framework for assessing and optimizing existing research networks
Conservation 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 ...

Conservation Biology, EarlyView.Abstract Despite the crucial role of human impacts on biodiversity loss, many assessments of this loss focus on single metrics, such as species richness, and overlook the multidimensional effects of human activities. Because of its importance to ecosystem functioning, we investigated the functional diversity of medium‐ and large‐sized mammal ...

Gaoya dianqi, 2021 近年来高压电缆缓冲层故障频发,可能由波纹护套与缓冲层空气间隙局部电场畸变引起,现有电场仿真研究缺乏对波纹护套压纹深度、节距以及缓冲层阻抗的考虑。文中基于麦克斯韦方程建立了考虑电缆波纹金属护套实际几何结构的数值仿真模型和平滑金属护套电缆的电路计算模型,定量分析了110 kV电缆缓冲层材料电导率和介电常数以及波纹金属护套几何结构对空气间隙电势与电场分布的影响。研究表明,当缓冲层材料电导率在10-6～10-9S/m时,空气间隙电势主要受缓冲层材料电导率的影响;当缓冲层材料电导率小于10-9S/m时 ...

Effects of landscape fragmentation on floodplain fishes as revealed by species–habitat networks
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract How species interact with habitat patches is influenced primarily by habitat configuration (e.g., connectivity) and species’ functional traits. As levels of fragmentation increase, identifying the intricate connections between these components is crucial for biodiversity conservation.
