MagMIMO consumes as much power as existing solutions, yet it can charge a phone remotely without being removed from the user's pocket.
As a consequence, if the S4 moved, it would carry either no charge, or at most half of what is expected from fully charged arginines.
But bigger pulse voltage could increase the charge accumulation.
For low applied voltage, the later stage charge process seems to follow the d(2) dependence.
We are not harmed by this high voltage, because the amount of charge that flows is puny.

What the best transformer method for code generation?
5 answers
The best transformer method for code generation is the SeTransformer proposed in the paper by Li et al. This method addresses the long-term dependence problem by utilizing code tokens and abstract syntax trees (AST) to extract information and leveraging the self-attention mechanism to analyze both text and structural features simultaneously. Another notable transformer method for code generation is the ALSI-Transformer introduced by Soselia and Saifullah, which aligns lexical and syntactic information using the Code-Aligned Type sequence (CAT) and encodes this aligned multi-modal information with convolution and embedding aggregation layers, achieving state-of-the-art performance in code comment generation. Both SeTransformer and ALSI-Transformer represent significant advancements in transformer-based approaches for generating code comments.
