Discovery of synchronized periodic variability of methanol maser features in G26.598-0.024
Aims. We report the discovery of periodic maser variability of an unusual pattern in the high-mass young stellar object G26.598-0.024. Methods. A ten-year monitoring of the 6.7 GHz methanol maser was carried out with the Torun 32 m radio telescope. The archival data collected so far were also used to characterize the target with high angular resolution and examine its infrared variability. Results. We found anticorrelated flux variations of the opposite blueshifted and redshifted emission featu…

Critic as Censor: How the Humanities Sacrificed Art at the Altar of Theory
My beloved friend, mentor, and Columbia University Professor Howard Stein, was fond of saying, “The Enemy of the Arts is the Humanities.” That insight, and advice, has stuck with me over the past 35 years. Now, that phrase is not the glib provocation it may seem. It is a precise diagnosis of an institutional disease, a declaration of war against a century of academic drift that has created a…

Spectral properties of graphs associated to the Basilica group
We provide the foundation of the spectral analysis of the Laplacian on the orbital Schreier graphs of the Basilica group, the iterated monodromy group of the quadratic polynomial $z^2-1$. This group is an important example in the class of self-similar amenable but not elementary amenable finite automata groups studied by Grigorchuk, Żuk, \v Sunić, Bartholdi, Virág, Nekrashevych, Kaimanovich, Nagnibeda et al. We prove that the spectrum of the Laplacian has infinitely many gaps and that the su…

Applying XAI based unsupervised knowledge discovering for Operation modes in a WWTP. A real case: AQUAVALL WWTP
Water reuse is a key point when fresh water is a commodity in ever greater demand, but which is also becoming ever more available. Furthermore, the return of clean water to its natural environment is also mandatory. Therefore, wastewater treatment plants (WWTPs) are essential in any policy focused on these serious challenges. WWTPs are complex facilities which need to operate at their best to achieve their goals. Nowadays, they are largely monitored, generating large databases of historical d…

A decisive Theorem (Un théorème décisif)
We give an elementary proof of the theorem which states that a finite unramified algebra over a discrete field is tracically étale. -- Nous donnons une démonstration élémentaire du théorème selon lequel toute algèbre nette sur un cors discret est étale, de dimension finie comme espace vectoriel et traciquement étale.

Olivier Blanchard, former chief economist of the International Monetary Fund, published a poem on the social media that describes Mr. Trump’s negotiating technique, and the EU’s response:
“I am going to cut your arm.
Please do not, please, please
Ok, I shall be generous, and just cut your thumb.
Thank you, thank you. You are so generous."
