For more than a century, putrid fumes emanated from
the “sewer of the Ruhr”,
creating a pungent whiff that assaulted towns throughout Germany’s industrial heartland.
But today, the Emscher bears little resemblance to Europe’s dirtiest river.
Water that used to be fouled by factory waste and human excrement have been free from effluent since 2021.
The river system, the main part of which was once considered biologically dead, is witnessing the return of an abun…

Multi-GPU Acceleration of PALABOS Fluid Solver using C++ Standard Parallelism
This article presents the principles, software architecture, and performance analysis of the GPU port of the lattice Boltzmann software library Palabos (J. Latt et al., "Palabos: Parallel lattice Boltzmann solver", Comput. Math. Appl. 81, 334-350, (2021)). A hybrid CPU-GPU execution model is adopted, in which numerical components are selectively assigned to either the CPU or the GPU, depending on considerations of performance or convenience. This design enables a progressive porting strategy, a…

Good Morning #Canada
Conservationists who focus on restoration of wetlands are increasingly "Leaving It To Beaver." Beavers are considered the ultimate Keystone Species because they area they re-engineer offer benefits to many other species, and an entire ecosystem can collapse if a Beaver is removed. A Beaver dam doesn't just hold and conserve water. Beavers increase the population of frogs, fish, insects, birds, and small mammals and extend the range of larger mammals like moose, deer, and bears. The quantity and variety of vegetation are increased. Water is filtered and saturates the land, refilling artesian wells. It's unbelievable that we almost lost this amazing creature because of a hat fashion trend.

A three-step approach to reliably estimate magnetic field strengths in star-forming regions
The magnetic field is known to play a crucial role in star formation. Dust polarization is an effective tool for probing the morphology of the field, yet it does not directly trace its strength. Several methods have been developed, combining polarization and spectroscopic data, to estimate the strength of the magnetic field, including the DCF method, which relates these quantities to the magnetic-field strength under the assumption of Alfvénic turbulence. Skalidis & Tassis (2021) (ST), relaxed…

Intellectual Property Rights and Entrepreneurship in the NFT Ecosystem: Legal Frameworks, Business Models, and Innovation Opportunities
Non Fungible Tokens have changed digital ownership and how creators earn money. Between 2021 and 2024, the market value exceeded 40 billion. However, the fast growth of the NFT ecosystem has revealed serious issues in managing intellectual property rights. There is a lot of confusion about the difference between owning an NFT and owning the copyright for the underlying content. This research looks at the gap between traditional copyright laws and blockchain-based transactions. We use a mixed me…

Counting distinct (non-)crossing substrings
Let $w$ be a string of length $n$. The problem of counting factors crossing a position - Problem 64 from the textbook ``125 Problems in Text Algorithms'' [Crochemore, Leqroc, and Rytter, 2021], asks to count the number $\mathcal{C}(w,k)$ (resp. $\mathcal{N}(w,k)$) of distinct substrings in $w$ that have occurrences containing (resp. not containing) a position $k$ in $w$. The solutions provided in their textbook compute $\mathcal{C}(w,k)$ and $\mathcal{N}(w,k)$ in $O(n)$ time for a single positi…

Proof of the linkage conjecture for highly connected tournaments

Proof of the linkage conjecture for highly connected tournaments
A digraph $D$ is $k$-linked if for every $2k$ distinct vertices $ x_1,\ldots , x_k, y_1, \ldots , y_k$ in $D$, there exist $k$ pairwise vertex-disjoint paths $P_1,\ldots, P_k$ such that $P_i$ starts at $x_i$ and ends at $y_i$ for each $i\in [k]$. In 2021, Girão, Popielarz, and Snyder [Combinatorica 41 (2021) 815--837] conjectured that there exists a constant $C >0$ such that every $(2k+1)$-connected tournament with minimum out-degree at least $Ck$ is $k$-linked. In this paper, we disprove this…

Unveiling the Complex Jet Dynamics in the Blazar 2021+317 through Multi-Epoch VLBI Observations
We present an investigation of the compact structure of the AGN 2021+317 based on multi-epoch Very Long Baseline Interferometry (VLBI) observations at 15, 22, and 43 GHz in the period from 2013 through 2024. The VLBI images show a core-jet structure extended to the south, with two stationary components in the northern region, one of which likely to be the core of the source. We also detected two new moving jet components (S4 and S5) in the observations of 2021. Based on these observational find…

Quantum Hamming Metrics
Given the set of words of a given length for a given alphabet, the Hamming metric between two such words is the number of positions where the two words differ. A quantum version of the corresponding Kantorovich-Wasserstein metric on states was introduced in 2021 by De Palma, Marvian, Trevisan and Lloyd. For the quantum version the alphabet is replaced by a full matrix algebra, and the set of words is replaced by the tensor product of a corresponding number of copies of that full matrix algebra.…
