Amazon Threat Intelligence observed sustained targeting of global infrastructure between 2021-2025, with particular focus on the energy sector, by Russian state-sponsored threat actors.

Amazon Threat Intelligence identifies Russian cyber threat group targeting Western critical infrastructure | Amazon Web Services
As we conclude 2025, Amazon Threat Intelligence is sharing insights about a years-long Russian state-sponsored campaign that represents a significant evolution in critical infrastructure targeting: a tactical pivot where what appear to be misconfigured customer network edge devices became the primary initial access vector, while vulnerability exploitation activity declined. This tactical adaptation enables the same […]

Big news for the energy transition!
And a nice little 'told you so' moment for yours truly :)
In the first half of this year, renewables produced more electricity globally than coal, for the first time.
And 2025 is the date I predicted for this to happen, back in 2016, in a blog post for Ecofys! The score was 23%-40% at the time, with most of the renewables share still coming from hydro, and the prediction was less than obvious.

Uniqueness of entire function concerning derivatives and shifts

Uniqueness of entire function concerning derivatives and shifts
In the paper, we investigate the uniqueness problem of entire function concerning its derivative and shift and obtain two results. On of our result solves the open problem posed by Majumder et al. (On a conjecture of Li and Yang, Hiroshima Math. J., 53 (2023), 199-223) and the other result improves and generalizes the recent result due to Huang and Fang (Unicity of entire functions concerning their shifts and derivatives, Comput. Methods Funct. Theory, 21 (2021), 523-532) in a large extend.

Funding, authorship patterns and citation impact of articles funded by Ukrainian agencies before and during Russia's full-scale war (2020-2023)
This study examines how Russia's full-scale war against Ukraine affected foreign co-funding, authorship patterns, and the citation impact of articles funded by the Ministry of Education and Science of Ukraine (MESU), the National Academy of Sciences of Ukraine (NASU), and the National Research Foundation of Ukraine (NRFU). The analysis includes articles in Scopus-indexed journals between 2020 and 2023. The share of articles funded by these agencies increased from 8.6% in 2020-2021 to 11.9% in 2…

Optimally building spanning graphs in semirandom graph processes
The semirandom graph process constructs a graph $G$ in a series of rounds, starting with the empty graph on $n$ vertices. In each round, a player is offered a vertex $v$ chosen uniformly at random, and chooses an edge on $v$ to add to $G$. The player's aim is to make $G$ satisfy some property as quickly as possible. Our interest is in the property that $G$ contain a given $n$-vertex graph $H$ with maximum degree $Δ$. In 2021, Ben-Eliezer, Gishboliner, Hefetz and Krivelevich showed that there i…
