Green hydrogen development threatens wildlife in Chile
Green hydrogen promoters tout it as the clean energy of the future. In 2020, Chile launched its National Green Hydrogen Strategy, looking to position the country as a leader in producing and exporting hydrogen by 2030 while reaching carbon neutrality. “Today we are taking a new step forward in producing clean energy, protecting nature and […]

Economic growth is incompatible with biodiversity conservation
The increase in resource consumption and polluting emissions as a result of economic growth is not compatible with biodiversity conservation. However, most international policies on biodiversity and sustainability advocate economic growth. These are the main conclusions of the study "Biodiversity policy beyond economic growth," published this week in the scientific journal Conservation Letters. This contradiction became clear after a review of international scientific and policy work on the sub…

Aggregate-Combine-Readout GNNs Are More Expressive Than Logic C2
In recent years, there has been growing interest in understanding the expressive power of graph neural networks (GNNs) by relating them to logical languages. This research has been been initialised by an influential result of Barceló et al. (2020), who showed that the graded modal logic (or a guarded fragment of the logic C2), characterises the logical expressiveness of aggregate-combine GNNs. As a ``challenging open problem'' they left the question whether full C2 characterises the logical ex…

On June 15, 2020, the official data protection impact assessment (DPIA) for the German Corona-Warn-App (CWA) was made publicly available. Shortly thereafter, the app was made available for download in the app stores. However, the first version of the DPIA had significant weaknesses, as this paper argues. However since then, the quality of the official DPIA increased immensely due to interventions and interactions such as an alternative DPIA produced by external experts and extensive public disc…

The impact of Alfvenic shear flow on magnetic reconnection and turbulence
Magnetic reconnection is a fundamental and omnipresent energy conversion process in plasma physics. Novel observations of fields and particles from Parker Solar Probe (PSP) have shown the absence of reconnection in a large number of current sheets in the near-Sun solar wind. Using near-Sun observations from PSP Encounters 4 to 11 (Jan 2020 to March 2022), we investigate whether reconnection onset might be suppressed by velocity shear. We compare estimates of the tearing mode growth rate in the …

However, as digital twins become more sophisticated and integral to decision-making processes, ensuring their accuracy, reliability, and ethical implementation is essential. This paper pr…

By being flexible about the location or width of the center, this measure enables the researcher to analyze polarization around any point of interest. The paper then applies this approach to US voter survey data between 2004 and 2020, showing how polarization between right-of-center voters and the rest of the electorate was increasing gradually, while polarization between left-wing…

Towards Skeletal and Signer Noise Reduction in Sign Language Production via Quaternion-Based Pose Encoding and Contrastive Learning
One of the main challenges in neural sign language production (SLP) lies in the high intra-class variability of signs, arising from signer morphology and stylistic variety in the training data.

First, we encode poses using bone rotations in quaternion space and train with a geodesic loss to improve the accuracy and clarity of angular joint mov…

Exceptional Hermite Polynomials and Calogero-Moser Pairs
There are two equivalent descriptions of George Wilson's adelic Grassmannian $Gr^{ad}$, one in terms of differential ``conditions'' and another in terms of Calogero-Moser Pairs.

This suggests that Calogero-Moser Pairs should also be useful in the study of Exceptional Hermite Polynomials, but no researchers have pursue…

Good Morning #Canada
#HappyBirthday to me. It's my 69th, and mentally, I feel young, but parts of my body have exceeded the "best before date." According to bornglorious .com there are 137 "famous" Canadians born on August 24th. Most are nobodies like me - politicians, actors, or NHL players you've never heard of. But there are a few notables. Like Alex Colville (1920-2013), a favourite Canadian conceptual painter. Or chain-smoker René Lévesque (1922-1987), who tried to tear Canada apart. But perhaps the Canadian born on this day with the most impact is Rocky Johnson (1944-2020). Born in Amherst, Nova Scotia, Johnson was a Canadian pro wrestler and the first black champion in WWE history. Oh yeah.... he was also the father of Dwayne "The Rock" Johnson.

Tracking the affordability of least-cost healthy diets helps guide intervention for food security and improved nutrition
This Policy Comment describes how the Food Policy article entitled 'Cost and affordability of nutritious diets at retail prices: Evidence from 177 countries' (first published October 2020) and 'Retail consumer price data reveal gaps and opportunities to monitor food systems for nutrition' (first published September 2021) advanced the use of least-cost benchmark diets to monitor and improve food security. Those papers contributed to the worldwide use of least-cost diets as a new diagnostic indic…

In 2020 hat der Eriba Nova 545 eine Gasdichtigkeitsprüfung bekommen. Zwei Jahre später wurde ich darauf hingewiesen, dass mein Druckminderer zu alt sei. Aber da die Gasdichtigkeitsprüfung da noch nicht wieder Pflicht war, habe ich eben keine machen lassen. Natürlich …

A comparison of variable selection methods and predictive models for postoperative bowel surgery complications
Accurate prediction of postoperative complications can support personalized perioperative care. However, in surgical settings, data collection is often constrained, and identifying which variables to prioritize remains an open question. We analyzed 767 elective bowel surgeries performed under an Enhanced Recovery After Surgery protocol at Medisch Spectrum Twente (Netherlands) between March 2020 and December 2023. Although hundreds of variables were available, most had substantial missingness or…

A Demonstration of Interstellar Navigation Using New Horizons
As NASA's New Horizons spacecraft exits the Solar System bound for interstellar space, it has traveled so far that the nearest stars have shifted markedly from their positions seen from Earth. We demonstrated this by imaging the Proxima Centauri and Wolf 359 fields from Earth and New Horizons on 2020 April 23, when the spacecraft was 47.1 au distant. The observed parallaxes for Proxima Centauri and Wolf 359 are $32.4''$ and $15.7'',$ respectively. These measurements are not of research grade, b…
