"Millions of Britons face higher risk of heart failure due to dirty air, study suggests"
#UK #UnitedKingdom #AirPollution

Interesting that some who replied to my post on tax and GDP growth yesterday missed the point.
The point isn't to debate whether tax -> growth (it might, with a tail wind).
The point is that
1) Growth won't happen like it used to.
2) That is good because GDP growth is ecologically and socially lethal.
3) So our leaders (sic) had better adapt to the new reality and use taxation and other measures to build a better, fairer future.

Getting Real about the Crises Facing the UK | Stop the Damage! Build a Better Future!
Britain and the rest of the world face a set of almost intractable challenges, ecological (including climate), economic and social. Yet political leaders with few exceptions are failing to propose the actions and policies that could address the scale of this pancrisis. Here though is an alternative initiative, a kind of alternative manifesto with a portfolio of illustrative policies...

Two seventh-century people found with west African ancestry – a story of diversity and integration in early Anglo-Saxon society
We should not be surprised that there are west Africans in early medieval Britain, the clues were there.

Gibt Slowakei Blockade gegen Sanktionen auf?
In der kommenden Woche sollen die EU-Außenminister erneut über die Lage in der Ukraine beraten. Voraussichtlich wird auch das geplante 18. Sanktionspaket gegen Russland eine Rolle spielen. Derzeit werden die weiteren Strafmaßnahmen durch das Veto der Slowakei blockiert. Doch der slowakische Ministerpräsident Robert Fico äußerte sich nun kompromissbereit. Eine Einigung sei möglich, …

Cost-Effective Strategies for Infectious Diseases: A Multi-Objective Framework with an Interactive Dashboard
During an infectious disease outbreak, policymakers must balance medical costs with social and economic burdens and seek interventions that minimize both. To support this decision-making process, we developed a framework that integrates multi-objective optimization, cost-benefit analysis, and an interactive dashboard. This platform enables users to input cost parameters and immediately obtain a cost-optimal intervention strategy. We applied this framework to the early outbreak of COVID-19 in So…

A New Proof of Meissner's Optimal Bound on the Degree of a Poincar\'e Multiplier and an Improved Optimal Degree Multiplier

A New Proof of Meissner's Optimal Bound on the Degree of a Poincaré Multiplier and an Improved Optimal Degree Multiplier
Let $f$ be a monic univariate polynomial. We say that $f$ is positive if $f(x)$ is positive over all $x > 0$. If all the coefficients of $f$ are non-negative, then $f$ is trivially positive. In 1883, Poincaré proved that $f$ is positive if and only if there exists a monic polynomial $g$ such that all the coefficients of $gf$ are non-negative. Such polynomial $g$ is called a Poincaré multiplier for the positive polynomial $f$. Of course one hopes to find a multiplier with smallest degree. In 1…

Many hope that AI will discover ethical truths. But as Gödel shows, deciding what is right will always be our burden

Search for an eV-scale sterile neutrino with the first six detection units of KM3NeT/ORCA
The existence of an eV-scale sterile neutrino has been proposed to explain several anomalous experimental results obtained over the course of the past 25 years. The first search for such a sterile neutrino conducted with data from KM3NeT/ORCA -- a water Cherenkov neutrino telescope under construction at the bottom of the Mediterranean Sea -- is reported in this paper. GeV-scale atmospheric neutrino oscillations are measured by reconstructing the energy and arrival direction of up-going neutrino…

Linearization of finite subgroups of Cremona groups over non-closed fields

Linearization of finite subgroups of Cremona groups over non-closed fields
We study linearizability properties of finite subgroups of the Cremona group ${\mathrm{Cr}}_n(k)$ in the case where $k$ is a global field, with the focus on the local-global principle. For every global field $k$ of characteristic different from 2 and every $n \ge 3$ we give an example of a birational involution of $\mathbb P^n_k$ (=an element $g$ of order $2$ in ${\mathrm{Cr}}_n(k)$) such that $g$ is not $k$-linearizable but $g$ is $k_v$-linearizable in ${\mathrm{Cr}}_n(k_v)$ for all places $v$…
