Lower numbers in Flensburg🇩🇪 are always desirable - whether it's points for German drivers (traffic fines) - or district heating temperatures. By reducing the need for 95°C heat from 10 > 1%, it's much easier to let heat pumps take over most of the heat supply. That's what the local utility will do.

Transformation in Flensburg: low temperatures for efficient heat pumps
As an innovative public utility company, Stadtwerke Flensburg is committed to decarbonisation and CO2 neutrality. To achieve this goal, the municipal utility company is working with Gradyent to reduce temperatures in the district heating system. As part of the partnership, the two companies have found a way to reduce the necessary annual heat share with a temperature above 95°C from around 10% to 1%. This means that heat pumps can be used to a higher extent and operated efficiently.

Asymptotic behavior of solutions of the fractional heat equation on Riemannian symmetric spaces of non-compact type
The main goal of this paper is to study the asymptotic behaviour of solutions to the heat equation and the fractional heat equations on a Riemannian symmetric space of non-compact type. For $α\in (0,1]$, let $h_t^α$ denote the fractional heat kernel on a Riemannian symmetric space of non-compact type $X=G/K$ (see Section \ref{sef1}). We show that if $p \in [1,2]$ and $f \in L^1(X)$ is $K$-bi-invariant, then \[\lim_{t\to\infty}\frac{\|f\ast h_t^α-\what f(i γ_p ρ)h_t^α\|_p}{\|…

What does Alexei Navalny’s death tell us? That Putin seems to be devising his most ominous scheme yet

If you're going to run an e-bike rebate program, it's probably important to pick a goal that you want to hit with it, because what your goal is should drive how the rebate program is designed.
Is your goal to provide economic benefit to low income households? Is it to reduce vehicle miles traveled (my recommendation)? Is it to get more bikes on the road and build a mass movement? (rebates probably not the right tool)

Tell Congress: Stop the TikTok Ban
Congress is fast-tracking a bill that would effectively ban TikTok in the US, but do little for its alleged goal of protecting our private information and the collection of our data by foreign governments. Tell Congress: Instead of giving the President the power to ban entire social media platforms based on their country of origin, our representatives should focus on what matters—protecting our data no matter who is collecting it.

“For millennials and the younger generation Z and Alphas, who may never be able to afford to buy a home or retire at a reasonable age, there is a growing feeling online that hard work is fortifying a system that, at best, is giving them nothing back and, at worst, is actively screwing them over. […] The goal of a softer life is more time and energy for what makes you happy and as little time as possible focusing on what doesn’t.”

Not satisfied with returning #abortion regulation to the states, anti-abortion activists see fetal personhood measures as an incremental back-door strategy to a national abortion ban.

Seeing Fetal ‘People’ Everywhere: What Has 'Dobbs' Wrought? - Ms. Magazine
The anti-abortion movement moved a step closer to realizing its goal of achieving fetal personhood when the Alabama Supreme Court held that frozen embryos are children for purposes of the state’s Wrongful Death of a Minor Act. However, the 8-1 ruling is a victory with a discernable twist. Republican lawmakers and their allies are now scrambling since at least three Alabama IVF providers have suspended their family-building services while they sort out the ruling's implications.

The Bayes Principle and Segal Axioms for $P(ϕ)_2$, with application to Periodic Covers
The goal of the present paper is to reconcile the so-called $P(ϕ)_2$ model from classical constructive quantum field theory (CQFT) with (metric version of) geometric and categorical axioms proposed by G. Segal \cite{Segal} in the 90's, in showing that the $P(ϕ)_2$ model satisfies these axioms, appropriately adjusted. The approach is based on previous works of Dimock arXiv:math-ph/0305017 and Pickrell arXiv:math-ph/0702077, while we give a new proof to a key step using what we call ``the Bayes…

Performance is not enough: the story told by a Rashomon quartet
The usual goal of supervised learning is to find the best model, the one that optimizes a particular performance measure. However, what if the explanation provided by this model is completely different from another model and different again from another model despite all having similarly good fit statistics? Is it possible that the equally effective models put the spotlight on different relationships in the data? Inspired by Anscombe's quartet, this paper introduces a Rashomon Quartet, i.e. a s…

List homomorphisms by deleting edges and vertices: tight complexity bounds for bounded-treewidth graphs
The goal of this paper is to investigate a family of optimization problems arising from list homomorphisms, and to understand what the best possible algorithms are if we restrict the problem to bounded-treewidth graphs. For a fixed $H$, the input of the optimization problem LHomVD($H$) is a graph $G$ with lists $L(v)$, and the task is to find a set $X$ of vertices having minimum size such that $(G-X,L)$ has a list homomorphism to $H$. We define analogously the edge-deletion variant LHomED($H$).…

From Data Creator to Data Reuser: Distance Matters
Sharing research data is complex, labor-intensive, expensive, and requires infrastructure investments by multiple stakeholders. Open science policies focus on data release rather than on data reuse, yet reuse is also difficult, expensive, and may never occur. Investments in data management could be made more wisely by considering who might reuse data, how, why, for what purposes, and when. Data creators cannot anticipate all possible reuses or reusers; our goal is to identify factors that may a…

A Jacobi-type Newton method for Nash equilibrium problems with descent guarantees
A common strategy for solving an unconstrained two-player Nash equilibrium problem with continuous variables is applying Newton's method to the system of nonlinear equations obtained by the corresponding first-order necessary optimality conditions. However, when taking into account the game dynamics, it is not clear what is the goal of each player when considering that they are taking their current decision following Newton's iterates. In this paper we provide an interpretation for Newton's ite…

Learnability Gaps of Strategic Classification
In contrast with standard classification tasks, strategic classification involves agents strategically modifying their features in an effort to receive favorable predictions. For instance, given a classifier determining loan approval based on credit scores, applicants may open or close their credit cards to fool the classifier. The learning goal is to find a classifier robust against strategic manipulations. Various settings, based on what and when information is known, have been explored in st…

Recently I've added a cheap hack to the standard #Gentoo invocation for #PyTest to throw errors if unhandled async functions are detected. The goal was to increase our chances of finding packages with missing dependency on dev-python/pytest-asyncio (or another equivalent plugin), or packages disabling plugin autoloading and failing to load such a plugin.
Today, I've gotten a first bug report, regarding dev-python/ipython. I've grepped the sources and confirmed that the package depends on PyTest-AsyncIO, except that it pins to < 0.22. Well, we don't have one that old but let's hope it works anyway. So I've tried adding the dep, `-p asyncio`… and PyTest still apparently couldn't find the plugin. I've scratched my head and tried `PYTEST_PLUGINS` instead — still the same result. What the…?
So I've checked the git repository out, tried with older PyTest-AsyncIO, and indeed the tests worked. Tried with the newest, 0.23.6, and the same issue occurred. I've checked the git history and discovered that the version pin was added because of a buggy 0.22.0 release. However, the issue has been fixed since, the release was yanked and my problem was nothing like that.
So I've investigated more. For some reason, #IPython test suite does not mark tests with `pytest.mark.asyncio` marker directly. Instead, it globally iterates over all test functions, and implicitly adds the marker to all coroutines. This used to work with older versions, but does not work anymore — the test is correctly marked, but for some reason it stops being recognized as a coroutine. So I've made a minimal reproducer and filed a bug.
The key point here is: the (potential) bug went unnoticed for a while now, because of the premature, then obsolete pin in IPython.

Sparse Representer Theorems for Learning in Reproducing Kernel Banach Spaces
Sparsity of a learning solution is a desirable feature in machine learning. Certain reproducing kernel Banach spaces (RKBSs) are appropriate hypothesis spaces for sparse learning methods. The goal of this paper is to understand what kind of RKBSs can promote sparsity for learning solutions. We consider two typical learning models in an RKBS: the minimum norm interpolation (MNI) problem and the regularization problem. We first establish an explicit representer theorem for solutions of these prob…
