Grok 4 is a huge leap from Grok 3, but how good is it compared to other models in the market, such as Gemini 2.5 Pro? We now have answers, thanks to new independent benchmarks.

Using PFES, we show that stable, globular protein folds could evolve from random amino acid sequences with relative ease, resulting from selection acting on a realistic number of amino acid ...

In this paper, we consider the design issue of a total secrecy coding scheme on remote estimation against eavesdroppers with anti-coding mechanisms. To be more specific, a legitimate user estimates ...

This puzzle’s combination of seeming impenetrability, generative complexity and a simple solution makes the sequence delightful to solve and to share.

To resist such illegal entities, we design a total secrecy coding scheme with true random sequences. Compared with the existing results, this scheme can reduce the cost and is difficult for attackers ...
