We present an empirically based model for teaching about planning in pre-service science teacher education as part of on-campus courses. Planning is usually taught through the introduction theoretically models, but these models commonly assume a linear idea that does not match how teachers go planning. examined middle school planned 20-minutes microteaching lesson on sustainable development.

Abstract. Due to the scarcity of labeled data, using supervised models pre-trained on ImageNet is a de facto standard in remote sensing scene classification. Recently, availability larger high resolution (HRRS) image datasets and progress self-supervised learning have brought up questions whether pre-training still necessary for classification would HRRS or achieve better results target tasks. ...

It is well understood how a variety of Ig H and L chains, components of BCR, are generated in the DNA level during B cell development. However, it has remained largely unknown whether and how each component is monitored for its quality and selected before the assembly into the BCR. Here we show that muH chains produced by pre-B cells display a wide spectrum of ability to form the pre-BCR, which...
