Psychometric framework for coexistence with large carnivores
Abstract Human–carnivore coexistence is essential for biodiversity conservation, yet measuring the attitudes and behaviors that support it remains methodologically challenging. We developed psychometric scales to assess willingness to coexist with carnivores and the underlying beliefs of this coexistence through an iterative expert elicitation process ...

18F-FDG PET/CT预测弥漫大B细胞淋巴瘤化疗后无进展生存期
目的评估18F-FDG PET/CT不同代谢参数在分析弥漫性大B细胞淋巴瘤(DLBCL)治疗响应中的预测价值。方法回顾性地选取2015年6月至2020年10月收治18F-FDG PET/CT的81例DLBCL患者。通过多元逻辑回归分析确定DLBCL治疗反应的预测因素,并根据这些因素创建预测模型。之后,通过特性曲线和校准图验证此预测模型的性能。结果首次化疗后2年内,23例患者(28.3%,23/81)疾病复发,58例患者(71.7%,58/81)无进展。本文分析了PET ...

基于地理信息元组的分类预测理论及应用——以中亚矿集区预测为例
地理信息科学的迅速发展为矿集区预测提供了新的理论依据,使地理信息理论、相应的技术方法组合及应用的整体研究成为可能。在大量理论和实验研究的基础上提出了基于地理信息元组的分类预测理论体系,该理论体系由六个概念、一个空间信息本质、两个空间信息特性以及六个空间信息相关方法和约定的构成。并在该理论体系基础上结合空间数据分析方法和探索式空间数据分析方法,建立了基于地理信息元组的分类预测模型。应用该模型在中亚区域实现了Au矿集区预测目标。为中亚成矿域中其它区域(如新疆 ...

Behavioral interventions to reduce demand for threatened freshwater turtles as pets
Abstract Growing demand for freshwater turtles as pets has fueled illegal trade and accelerated wild population declines, underscoring the need for theory‐based demand‐reduction interventions. We conducted a three‐part randomized controlled trial with active turtle keepers (n = 1800) in China to test conservation‐ and legality‐framed messages by ...

基于GWO-LSTM与NKDE的变压器油中溶解气体体积分数点——区间联合预测方法
变压器油中溶解气体体积分数是表征变压器健康状态及故障特性的重要参量。因此,准确预测变压器油中溶解气体的体积分数,有助于及时把握变压器的状态演化与故障发展趋势。现有对气体体积分数预测的研究多集中在点预测方面,难以全面反映气体体积分数的不确定性信息。针对此问题,提出了一种基于灰狼优化长短期记忆网络(long short-term memory based on grey wolf optimization,GWO-LSTM)与非参数核密度估计(non-parametric kernel density ...

Learning Styles, Engagement and Anxiety in AI‐Mediated Writing: A Multimodal Feedback Study
ABSTRACT Artificial intelligence (AI) tools now permeate English academic writing. However, evidence on how feedback modalities align with student differences and with psychological mechanisms remains limited. Prior work often reduced learning styles to simple matches with delivery modes and treated learning engagement and writing anxiety as peripheral.
