the advent of computer has revolutionized a variety of fields including education thus paving the way for educational science to enter a new stage. this effect has exhibited itself well in language learning. the development of computer technology and the resulting language learning software, as a reliable tool in the educational system of developed countries, has attracted the attention of both...

This study explored the effectiveness of the two computer-assisted modes: cooperative and individual on improving Iranian high school students’ reading comprehension. It was also concerned with investigating the effectiveness of the two computer-assisted modes on the participants’ foreign language learning anxiety (FLLA). The sample of the study consisted of two intact groups, each containing 2...

We study the joint active/passive beamforming and channel blocklength (CBL) allocation in a non-ideal reconfigurable intelligent surface (RIS)-aided ultra-reliable low-latency communication (URLLC) system. The considered scenario is finite (FBL) regime problem solved by leveraging deep reinforcement learning (DRL) algorithm named twin-delayed deterministic policy gradient (TD3). First, assuming...

Objective To understand the application and impact assessment of case-based learning (CBL) in standardized training Urology residents. Methods A retrospective analysis was carried out on teaching effect 76 trainees participated residents First Affiliated Hospital Nanjing Medical University from September 2018 to December 2020. Among them, there were 37 included before 2019, 39 after which latte...

Second language writing instruction has been greatly influenced by the growing importance of technology and the recent shift of paradigm from a cognitive to a social orientation in second language acquisition (Lantolf & Thorne, 2006). Therefore, the applications of computer assisted language learning and activity theory have been suggested as a promising framework for writing studies. The prese...

Casitas B-cell lymphoma (Cbl)-family E3 ubiquitin ligases are negative regulators of tyrosine kinase signaling. Recent work has revealed a critical role of Cbl in the maintenance of hematopoietic stem cell (HSC) homeostasis, and mutations in CBL have been identified in myeloid malignancies. Here we show that, in contrast to Cbl or Cbl-b single-deficient mice, concurrent loss of Cbl and Cbl-b in...
