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 Constructed value of information (CVoI) is an expert elicitation decision‐analytic tool used to prioritize sources of uncertainty based on their potential to improve decision outcomes if resolved. Despite increased application of CVoI, the robustness of CVoI prioritization of sources of uncertainty relative to differences in expert elicitation

Accountability in Government Use of AI: Citizen Concerns and Preferences
Public Administration, EarlyView.ABSTRACT Government adoption of AI opens the “pandora's box” of accountability, a core aspect of public value. Despite the centrality of governmental AI accountability, citizens' concerns and preferences in holding governments accountable for AI usage remain poorly understood.

Jixie chuandong, 1998 齿轮减速器的优化设计提高了设计的质量。但由于客观条件的千差万别，常常需要对不同设计要求的减速器进行优化设计。显然这是十分繁杂的工作。为了既能最大限度地满足不同设计要求的实际需要，又能简化其优化设计，本文以单级圆柱齿轮减速器为例进行优化设计，然后根据量纲理论，求出相似准则；通过简单的运算，将其优化设计参数转换为不同设计要求的其它齿轮减速器的优化设计中去。

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Because of superior transportability and high energy capacity, methanol is regarded as a potential hydrogen carrier. Photocatalytic methanol dehydrogenation offers a sustainable and cost‐effective method for releasing hydrogen. Conventional photocatalysts face challenging obstacles, including the low catalytic efficiency and rapid ...
