In-situ Hybridization

9.4K
In situ hybridization (ISH) is a technique used to detect and localize specific DNA or RNA molecules in cells, tissue, or tissue sections using a labeled probe. The technique was first used in 1969 for the investigation of nucleic acids. It is currently an essential tool in scientific research and clinical settings, especially for diagnostic purposes.
Types of probes and labels
A probe is a complementary strand of DNA or RNA that binds to corresponding nucleotide sequences in a cell. Many...

Stereotypes, Prejudice, and Discrimination

90.2K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

    概括

    这项研究介绍了MANet,这是一个基于文本的个人搜索 (TBPS) 的新型网络. MANet有效地在多个层面上对齐图像和文本功能,提高了人身识别准确度.

    科学领域:

    • 计算机视觉 计算机视觉
    • 人工智能的人工智能
    • 机器学习 机器学习

    背景情况:

    • 基于文本的人员搜索 (TBPS) 旨在使用文本描述识别图像中的个人.
    • 当前最先进的方法通常依赖于明确的本地零件生成,由于噪音和缺乏上下文,这种方法可能不可靠.
    • 现有的方法经常忽视图像和文本模式之间的信息不平等.

    研究的目的:

    • 为改进基于文本的人员搜索提出一个高效的联合多层次对齐网络 (MANet).
    • 解决现有方法的局限性,包括不可靠的细粒度通信和模式之间的信息不平等.
    • 通过加强跨模式功能对齐,实现快速有效的人员识别.

    主要方法:

    • 开发了一个特定于图像的信息抑制 (ISS) 模块,使用关系引导定位 (RGL) 和通道注意力过 (CAF) 来减轻背景噪声和环境因素.
    • 引入了一个隐式局部对齐 (ILA) 模块,用于将像素/词特征适应性聚合到共享模式的语义中心,从而实现隐式细粒度通信学习.
    • 整合了一个全球对齐 (GA) 模块来补充本地对齐,增强图像和文本模式之间的整体语义对齐.

    主要成果:

    • 国际空间站模块有效地压制图像特定信息,减少信息不平等,并在模式之间调整信息量.
    • ILA模块隐式地学习本地细粒度对应,而不需要额外的监督或跨模式交互.
