Assessing local deformation and computing scalar curvature with nonlinear conformal regularization of decoders
One aim of dimensionality reduction is to discover the main factors that explain the data, and as such is paramount to many applications. When working with high dimensional data, autoencoders offer a simple yet effective approach to learn low-dimensional representations. The two components of a general autoencoder consist first of an encoder that maps the observed data onto a latent space; and second a decoder that maps the latent space back to the original observation space, which allows to le…

"The Bus Services (No. 2) Bill became law on Monday night (27th October), enabling local transport authorities to implement franchising schemes for bus services in England – potentially reversing the decades-old deregulation of buses which opponents say has contributed to spiralling prices and worsening, reduced services while transport firms pay millions to shareholders."

After two decades in Congress,
Darrell Issa’s career is all about serving the ultra-wealthy like himself
– and serving Donald Trump. It’s time to send him packing and take our country back. 
On the City Council,
Marni von Wilpert
flipped San Diego’s reddest seat blue.
Now, she’s ready to do it again – in Congress.

Marni von Wilpert for Congress
Marni von Wilpert is running for Congress to tackle the skyrocketing cost of living, protect reproductive freedom, defend LGBTQ rights, and make Washington work for working families — not just the wealthy few. With a proven record of service, results, and winning tough races, Marni is the battle-tested fighter we need to flip CA-48 and finally send Darrell Issa packing.

Government Policies Drive Reduced Coastal Plastic Pollution on Australian Beaches | Happy Eco News
Australia has achieved reduced coastal plastic pollution with a 39% decrease over 10 years, according to new CSIRO research. The study of six cities shows government policies like plastic bans are working, though scientists say continued efforts from communities, industry, and policymakers remain essential for environmental protection.

This recent working paper by Robert Metcalfe e.a. for Centre for Net Zero (part of Octopus Group) shows how effective automated EV smart charging is:
"42% reduction in household electricity demand during peak hours, with 100% of this demand shifted to low-cost, low-emission off-peak periods."

Baues-Wirsching Cohomology and Svarc Genus in Small Categories
We prove that for a bifibration P between small categories, the lenght of the cup product in the kernel of the induced morphism in the Baues-Wirsching cohomology with coefficients in any natural system is a lower bound for the homotopic sectional category (also called Svarc genus). Our results extend classical Svarc type inequalties to the categorical setting and introduce a computationally efficient method via a reduced cochain complex for Baues-Wirching cohomology.

Realization of large magnetocaloric effect in the Kagome antiferromagnet Gd3BWO9 for Sub-Kelvin cryogenic refrigeration
Rare-earth (RE) based frustrated magnets have attracted great attention as excellent candidates for magnetic refrigeration at sub-Kelvin temperatures, while the experimental identification on systems exhibiting both large volumetric cooling capacity and reduced working temperatures far below 1 K remain to be a challenge. Here, through the ultra-low temperature magnetism and thermodynamic characterizations, we unveil the large magnetocaloric effect (MCE) realized at sub-Kelvin temperatures in th…

Computing with necklaces on elliptic curves
We present computational algorithms to work with points on the modular curve associated to the normaliser of a non-split Cartan group of prime level $p$. Rather than working with explicit equations, we represent these points using the moduli interpretation of necklaces in the $p$-torsion of elliptic curves. We use our methods to investigate for which primes $\ell\neq p$ two rational points with complex multiplication can have equal reduction modulo $\ell$.
