Anastasia Malashina, a doctoral student at HSE University, has proposed a new method to assess vulnerabilities in encryption systems, which is based on a brute-force search of possible options of symbol deciphering. The algorithm was also implemented in a programme, which can be used to find vulnerabilities in ciphers. The results of the study were published in a paper ‘Software development for the study of natural language characteristics’.
In 2012, many universities started signing incentive contracts with their staff in order to stimulate research and active inclusion in the global academic market. Together with orders issued by Russia’s president in May, this has led to growth in university salaries. But exactly which responsibilities increase pay — teaching, research or administrative work? The answer to this question will help improve the effective contract system to make it profitable both for teachers and universities.
From April 13 to 30, HSE University is hosting the XXII April International Academic Conference on Economic and Social Development, one of the most important annual events in Russian humanities. Profile talked to Lev Jakobson, co-chair of the conference organising committee and vice president of HSE University, about the challenges that researchers face today.

Let $W_G(q_1,q_2,\ldots)$ be a weighted symmetric chromatic polynomial of a graph $G$. S. Chmutov, M. Kazarian and S. Lando in the paper arXiv:1803.09800v2 proved that the generating function $\mathcal{W}(G)$ for the polynomials $W_G(q_1,q_2,\ldots)$ is a $\tau$-function of the Kadomtsev--Petviashvili integrable hierarchy. We proved that the function $\mathcal{W}(G)$ itself is a solution of a linear integrable hierarchy. Also we described the initial conditions for the general formal $\tau$-function of the KP-hierarchy which guarantee that the $\tau$-function is a solution of a linear integrable hierarchy.
