Scenarios and strategies for future‐proofing ecosystem management under climatic novelty

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
Abstract Climate change is driving unprecedented declines in dominant, habitat‐forming foundation species across marine and terrestrial ecosystems globally. As climatic novelty becomes the norm, ecosystem reassembly will become increasingly common. Predicting and understanding these transitions, and their implications for future ecosystem functioning ...

三维图像中物体体素重建的新方法(英文)

open access: yes四川大学学报. 自然科学版, 2003
在三维图像 ,例如LSCM ,CT和MRI图像的处理、识别、可视化和计算机绘图中 ,三维物体的重建是必不可少的 .已有的三维物体重建方法是基于二维物体重建的连通模拟法 ,因此重建速度慢 .为此 ,我们提出一种新的快速的三维物体体素重建方法 .在这种方法中 ,首先采用边沿跟踪和水平扫描的区域标号法重建三维图像的每个平面中的二维物体切片 ,然后采用伪OR运算和链接表的叠片法重建三维图像中的三维物体实体 .作者首先介绍边沿跟踪和水平扫描方法 ,然后介绍伪OR运算和链接表 ...

基于半监督生成对抗网络的三维重建云工作室

open access: yes智能科学与技术学报, 2019
由于固有的问题复杂性和计算复杂度,三维重建是计算机视觉研究和应用领域非常重要且富有挑战性的课题。目前已有的三维重建算法往往会导致重建的三维模型上存在着明显的空洞、扭曲失真或者模糊不清的部分,而基于机器学习的三维重建算法往往又只能重建简单的分离物体,并表示成三维体元形式。所以这些算法框架对于实际应用来说都还远远不够。从 2014 年起,生成对抗网络被广泛应用于半监督学习,以及产生非真实数据集的应用中。所以本文的重点是采用生产对抗网络原理,来获得高质量的三维重建效果。提出了一种新颖的半监督三维重建算法架构 ...

‘The Heart of the Matter’: Grandparent Childcare in Contemporary Chinese Families

open access: yesChildren &Society, Volume 40, Issue 3, Page 556-566, May 2026.
ABSTRACT Grandparent childcare is an international phenomenon, especially within families with children under 3 years old. China is no exception, as shown by a number of quantitative studies. Less clear is our understanding of the actual childcare arrangements involved and how these are negotiated and sustained through the intergenerational ...

岩石薄片三维重建训练图像分析

open access: yes四川大学学报. 自然科学版, 2013
基于二维图像的砂岩三维重建中,二维图像的空间结构分析是一个至关重要的环节.要成为三维随机模拟的训练图像,二维图像的空间结构统计特征必须满足平稳性和遍历性要求.本文通过多尺度纹理特征分析方法进行训练图像的平稳性分析,利用表征区域分析训练图像的遍历性.实验结果证明,满足平稳性和遍历性的训练图像能得到较好的三维重建结果,并提高了三维重建的效率.

Striking a balance: Stakeholder perceptions of risk in horse racing

open access: yesEquine Veterinary Journal, Volume 58, Issue 3, Page 814-823, May 2026.
Abstract Background Thoroughbred racing is a major industry, and in recent years public concerns about equine safety have become more prominent, particularly in relation to on‐track injuries and fatalities. This has challenged the industry's social licence to operate (SLO).

三维重建技术在食管癌术前诊断的临床应用价值

open access: yesZhongguo shiyan zhenduanxue, 2019
目的三维重建功能在临床上已被广泛应用于临床的术前诊断评估,但对于食管肿瘤术前评估的应用研究甚少。本研究旨在探讨三维重建技术在食管下段肿瘤患者术前诊断中的应用,以提高食管癌的诊断和治疗水平,为患者术前评估提供一种更精准、科学的方法。方法所有患者均于2014年1月至2015年8月在吉林大学第一医院接受食管癌治疗。本研究收集患者的影像资料,应用表面重建技术重建食管肿瘤及邻近结构。分析并计算肿瘤的形状和其他具体参数,并对不同条件下的三维重建结果进行比较。研究使用IBM SPSS 19对所有数据进行分析 ...
