Lite förenklat tror jag att jag kan påstå att matavfall bidrar till Sveriges energimix med 0,2% 2023.
Total energitillförsel 2023: 507 TWh
- Varav biobränslen: 149,6 TWh
Total biogasanvändning: 4,1 TWh
- Varav matavfall 24%, dvs 1 TWh
Har jag missat något här? Eller räknat uppåt väggarna? #energipolitik

From this year on, ESWC will be under the umbrella of SWSA, the Semantic Web Science Association, to secure financial sustainability for the upcoming years after its previous supporting organisation STI was dissolved in 2023. Basics about the transition are given by Elena Simperl, president of SWSA.

HouseTS: A Large-Scale, Multimodal Spatiotemporal U.S. Housing Dataset
Accurate house-price forecasting is essential for investors, planners, and researchers. However, reproducible benchmarks with sufficient spatiotemporal depth and contextual richness for long horizon prediction remain scarce. To address this, we introduce HouseTS a large scale, multimodal dataset covering monthly house prices from March 2012 to December 2023 across 6,000 ZIP codes in 30 major U.S. metropolitan areas. The dataset includes over 890K records, enriched with points of Interest (POI),…

Aus irgendeinem Grund ist gerade die Sonos-Radio-Station "The Lighthouse", über die Brian Eno jede Menge unveröffentlichte Tracks abspielen läßt, gratis (man braucht halt ein Sonos-Gerät dazu), und ich höre mich da nun etwas durch.

Brian Eno – The Lighthouse, what’s on it?
I’ve been compiling this, off and on, all year, while listening to the 340+ unreleased tracks on Brian Eno‘s Sonos HD radio station, The Lighthouse. If I had the phone nearby I’d check what’s playing, make a note of the track number and year and write a short description. I was intrigued to see how often tracks repeated (not very often), how long it would take me to hear all of them (over 6 months) and what the ratio of good to average to bad was. It became quite addictive as I’d fill…

Can Artificial Intelligence Trade the Stock Market?
The paper explores the use of Deep Reinforcement Learning (DRL) in stock market trading, focusing on two algorithms: Double Deep Q-Network (DDQN) and Proximal Policy Optimization (PPO) and compares them with Buy and Hold benchmark. It evaluates these algorithms across three currency pairs, the S&P 500 index and Bitcoin, on the daily data in the period of 2019-2023. The results demonstrate DRL's effectiveness in trading and its ability to manage risk by strategically avoiding trades in unfavorab…

Asteroseismology of the G8 subgiant beta Aquilae with SONG-Tenerife, SONG-Australia and TESS
We present radial velocities of the G8 subgiant star beta Aql obtained in 2022 and 2023 using SONG-Tenerife and SONG-Australia. We also analysed a sector of TESS photometry that overlapped with the 2022 SONG data. We processed the time series to assign weights and to remove bad data points. The power spectrum clearly shows solar-like oscillations centred at 430 muHz. The TESS data show the oscillations at lower signal-to-noise because photometric measurements are much more affected by the granu…

A Decidable Bundled Fragment of First-Order Modal Logic Without Finite Model Property

A Decidable Bundled Fragment of First-Order Modal Logic Without Finite Model Property
The satisfiability problem for First-order Modal Logic (\FOML) is undecidable even for simple fragments like having only unary predicates, two variables etc. Recently a new way to identify decidable fragments of \FOML has been introduced called the "bundled fragments", where the quantifiers and modalities are restricted to appear together. Since there are many ways to bundle the quantifiers together, some of them lead to (un)decidable fragments. In (Liu et.al, 2023) the authors prove a `trichot…

Speeding Up Hyper-Heuristics With Markov-Chain Operator Selection and the Only-Worsening Acceptance Operator
The move-acceptance hyper-heuristic was recently shown to be able to leave local optima with astonishing efficiency (Lissovoi et al., Artificial Intelligence (2023)). In this work, we propose two modifications to this algorithm that demonstrate impressive performances on a large class of benchmarks including the classic Cliff$_d$ and Jump$_m$ function classes. (i) Instead of randomly choosing between the only-improving and any-move acceptance operator, we take this choice via a simple two-state…

Minimum Membership Geometric Set Cover in the Continuous Setting
We study the minimum membership geometric set cover, i.e., MMGSC problem [SoCG, 2023] in the continuous setting. In this problem, the input consists of a set $P$ of $n$ points in $\mathbb{R}^{2}$, and a geometric object $t$, the goal is to find a set $\mathcal{S}$ of translated copies of the geometric object $t$ that covers all the points in $P$ while minimizing $\mathsf{memb}(P, \mathcal{S})$, where $\mathsf{memb}(P, \mathcal{S})=\max_{p\in P}|\{s\in \mathcal{S}: p\in s\}|$. For un…

On the homological shifts of cover ideals of Cohen-Macaulay graphs
For a non-negative integer $k$, let $\mathrm{HS}_{k}(J(G))$ denote the $k^{\text{th}}$ homological shift ideal of the vertex cover ideal $J(G)$ of a graph $G$. For each $k\geq 2$, we construct a Cohen-Macaulay very well-covered graph $G_k$ which is both Cohen-Macaulay bipartite and a whiskered graph so that $\mathrm{HS}_{k}(J(G))$ does not have a linear resolution. This contradicts several results as well as disproves a conjecture in [J. Algebra, $\mathbf{629}$, (2023), 76-108] and [Mediterr. J…

A large scaling property of level sets for degenerate $p$-Laplacian equations with logarithmic BMO matrix weights
In this study, we deal with generalized regularity properties for solutions to $p$-Laplace equations with degenerate matrix weights. It has already been observed in previous interesting works [A. Kh. Balci, L. Diening, R. Giova, A. Passarelli di Napoli, SIAM J. Math. Anal. 54(2022), 2373-2412] and [A. Kh. Balci, S.-S. Byun, L. Diening, H.-S. Lee, J. Math. Pures Appl. (9) 177(2023), 484-530] that gaining Calderón-Zygmund estimates for nonlinear equations with degenerate weights under the so-cal…

Why Academics Are Leaving Twitter for Bluesky
We analyse the migration of 300,000 academic users from Twitter/X to Bluesky between 2023 and early 2025, combining rich bibliometric data, longitudinal social-media activity, and a novel cross-platform identity-matching pipeline. We show that 18% of scholars in our sample transitioned, with transition rates varying sharply by discipline, political expression, and Twitter engagement but not by traditional academic metrics. Using time-varying Cox models and a matched-pairs design, we isolate gen…
