Welcome to acronym city! The Court of Appeal of Brussels has made an interesting ruling. A customer complained that their bank was spelling the customer's name incorrectly. The bank didn't have support for diacritical marks. Things like á, è, ô, ü, ç etc. Those accents are common in many languages. So it was a little surprising that the bank didn't support them. The bank refused to spell their c…

Surgeons Awareness, Expectations, and Involvement with Artificial Intelligence: a Survey Pre and Post the GPT Era
Artificial Intelligence (AI) is transforming medicine, with generative AI models like ChatGPT reshaping perceptions of its potential. This study examines surgeons' awareness, expectations, and involvement with AI in surgery through comparative surveys conducted in 2021 and 2024. Two cross-sectional surveys were distributed globally in 2021 and 2024, the first before an IRCAD webinar and the second during the annual EAES meeting. The surveys assessed demographics, AI awareness, expectations, inv…

Certification of High-Dimensional Entanglement Within the Resource Theory of Buscemi Nonlocality
The study on the certification of high degree entanglement, which is quantified in terms of Schmidt number, attracts much attention recently. Drawing inspiration from the work [PRX QUANTUM 2, 020301 (2021)], we first introduce resource theories of distributed measurements and teleportation instruments generated by a bipartite mixed state. Next we quantitatively characterized the relations among the convex resource theories of distributed measurements, teleportation instruments, and bipartite mi…

Refuting Perfect Matchings in Spectral Expanders is Hard
This work studies the complexity of refuting the existence of a perfect matching in spectral expanders with an odd number of vertices, in the Polynomial Calculus (PC) and Sum of Squares (SoS) proof system. Austrin and Risse [SODA, 2021] showed that refuting perfect matchings in sparse $d$-regular \emph{random} graphs, in the above proof systems, with high probability requires proofs with degree $Ω(n/\log n)$. We extend their result by showing the same lower bound holds for \emph{all} $d$-regul…

AI-Generated Compromises for Coalition Formation
The challenge of finding compromises between agent proposals is fundamental to AI subfields such as argumentation, mediation, and negotiation. Building on this tradition, Elkind et al. (2021) introduced a process for coalition formation that seeks majority-supported proposals preferable to the status quo, using a metric space where each agent has an ideal point. A crucial step in this process involves identifying compromise proposals around which agent coalitions can unite. How to effectively f…

Remarks on radial symmetry of stationary and uniformly-rotating solutions for the 2D Euler equation
We prove that any uniformly rotating solution of the 2D incompressible Euler equation with compactly supported vorticity $ω$ must be radially symmetric whenever its angular velocity satisfies $Ω\in (-\infty,\inf ω/ 2] \cup \, [ \sup ω/ 2, +\infty )$, in both the patch and smooth settings. This result extends the rigidity theorems established in \cite{Gom2021MR4312192} (\textit{Duke Math.

Assessing innovation in the nascent value chains of climate-mitigating technologies
Accelerating climate-tech innovation in the formative stage of the technology life cycle is crucial to meeting climate policy goals. During this period, competing technologies are often undergoing major technical improvements within a nascent value chain. We analyze this formative stage for 14 climate-tech sectors using a dataset of 4,172 North American firms receiving 12,929 early-stage private investments between 2006 and 2021. Investments in these firms reveal that commercialization occurs i…

Bounds on Functionality and Symmetric Difference -- Two Intriguing Graph Parameters
Functionality ($\mathrm{fun}$) is a graph parameter that generalizes graph degeneracy defined by Alecu et al. [JCTB, 2021]. They research the relation of functionality to many other graphs parameters (tree-width, clique-width, VC-dimension, etc.). Extending their research, we completely characterize the functionality of random graph $G(n,p)$ for all possible $p$. We provide matching (up to a constant factor) lower and upper bound for a large range of $p$. It follows from our bounds for $G(n,p)$…

A PBH with an initial mass of approximately $10^{15}$~g is expected to explode today in a final burst of Hawking radiation.

Rota-Baxter operators on compact simple Lie groups and algebras
A Rota-Baxter operator on a Lie group $ G $ is a smooth map $ B : G \to G $ such that $ B(g)B(h) = B(gB(g)hB(g)^{-1}) $ for all $ g, h \in G $. This concept was introduced in 2021 by Guo, Lang and Sheng as a Lie group analogue of Rota-Baxter operators of weight 1 on Lie algebras. We show that the only Rota-Baxter operators on compact simple Lie groups are the trivial map and the inverse map. A similar description for Rota-Baxter operators of weight 1 on compact simple Lie algebras is provided.

After a long term efforts, the Hamiltonian problem of connected vertex-transitive graphs of order $pq$ (where $p$ and $q$ are primes) was finally finshed in 2021, see [10]. Fifteen years ago, mathematicians began to challenge this problem for graphs of order $2pq$. Among of them, it was proved in 2012 (see [21]) that every connected vertex-transitive graph of order $10p$ (where $p\neq7$ is a prime) contains a Hamilton path, with the exception of a family of graphs which was recently confirmed i…

Very interesting talks at the #SolarEclipse Conference - https://www.vvs.be/subsite/sec-2025/programme - in Belgium I am attending online: here is the key result by Luca Quaglia who had reported his work in great detail in the papers https://iopscience.iop.org/article/10.3847/1538-4365/ac1279 (2021), https://www.iota-es.de/JOA/JOA2022_2.pdf#page=3 (2022) and https://www.iota-es.de/JOA/JOA2024_4.pdf#page=3 (2024) already. There seems to be NO way by now to escape the conclusion the the solar - i.e. photospheric - diameter used by many in the past (and various eclipse map calculations sites still today) is too small. So everyone should use Quaglia's free precision tools at https://www.besselianelements.com instead to get the real length of totality at one's observing spot. And when you are observing at the edges of the totality zone the tools will tell you where the actual border is: traditional maps can the off by some margin! 1/n
