The article focuses on completing the square with the use of TI-Nspire computer algebra system (CAS). It states that CAS automatically generates family members of squares for a specified trinomial p(x). It discusses the calculation of algebraic expressions in square completers using the CAS-...
In terms of datasets and benchmarks, protein design is far less mature than drug discovery (paperwithcode drug discovery benchmarks). (Maybe should add the evaluation of protein design for deep learning method (especially deep generative model)) Difficulties and opportunities always coexist. Happy...
Identifying pathogenic variants from the vast majority of nucleotide variation remains a challenge. We present a method named Multimodal Annotation Generated Pathogenic Impact Evaluator (MAGPIE) that predicts the pathogenicity of multi-type variants. MAGPIE uses the ClinVar dataset for training and demonst...
Using the method of Baron and Kenny (1986), the moderating effect of self-regulation skills was tested in the relationships between behavioral intention and actual behavior. 4. Results 4.1. Descriptive statistics Regarding the reasons why they learned English autonomously (see Table 3), over 50% ...
