Journal of Cognitive Engineering and Decision Making, 2023 A richer approach to studying Decision Support System (DSS) interactions is required to understand and predict the nature of actual use in the workplace. We used questionnaire and interview techniques to examine workers’ experiences relating to DSS use in naturalistic settings.

Waveform Reconstruction of DSSS Signal Based on VAE‐GAN
Wireless Communications and Mobile Computing, 2022 The complex electromagnetic environment will limit the efficacy of communication equipment. It is critical to construct a complex electromagnetic environment to test communication equipment in order to maximize its capability. One of the most important methods for constructing a complex electromagnetic environment is signal reconstruction.

The unusual gene architecture of polyubiquitin is created by dual-specific splice sites [PDF]
Genome BiologyBackground The removal of introns occurs through the splicing of a 5′ splice site (5′ss) with a 3′ splice site (3′ss). These two elements are recognized by distinct components of the spliceosome. However, introns in higher eukaryotes contain many matches
