Vatikan rudert nach umstrittenen Papst-Empfehlungen an Ukraine zurück
Der Vatikan rudert nach der umstrittenen Äußerung von Papst Franziskus zurück, die Ukraine solle die weiße Fahne hissen und mit Russland verhandeln. Die erste Bedingung für Verhandlungen zur Beendigung des Krieges in der Ukraine sei, dass Russland seine Aggression einstelle, sagte der Papst-Stellvertreter Kardinal Pietro Parolin in einem Interview mit "Corri…

Hydrodynamic simulations of WD-WD mergers and the origin of RCB stars
We study the properties of double white dwarf (DWD) mergers by performing hydrodynamic simulations using the new and improved adaptive mesh refinement code Octo-Tiger. We follow the orbital evolution of DWD systems of mass ratio q=0.7 for tens of orbits until and after the merger to investigate them as a possible origin for R Coronae Borealis (RCB) type stars. We reproduce previous results, finding that during the merger, the Helium WD donor star is tidally disrupted within 20-80 minutes since …

FAIRM: Learning invariant representations for algorithmic fairness and domain generalization with minimax optimality
Machine learning methods often assume that the test data have the same distribution as the training data. However, this assumption may not hold due to multiple levels of heterogeneity in applications, raising issues in algorithmic fairness and domain generalization. In this work, we address the problem of fair and generalizable machine learning by invariant principles. We propose a training environment-based oracle, FAIRM, which has desirable fairness and domain generalization properties under …

This week I feel as if I’ve forgotten how to write. It’s time to go back into the stream, to enter the waters. One way I do this is by invoking oracles and their art-counterparts, surrealist games and chance operations.
I’ve been at work creating some new writing oracles, but meanwhile here are two paragraphs from recent weeks where I am raising different forms of oracle-energy.

I can’t help thinking that whoever is pushing QR codes as a solution for connecting folk to information and services hasn’t realised how cheaply and easily the hack to subvert them is…. they’re called stickers 🤦‍♂️ https://qrcode.co.uk/blog/fake-qr-code-scams/

An open dataset for oracle bone script recognition and decipherment
Oracle Bone Script (OBS), one of the earliest known forms of ancient Chinese writing, holds invaluable insights into the humanities and geography of the Shang Dynasty, dating back 3,000 years. The immense historical and cultural significance of these writings cannot be overstated. However, the passage of time has obscured much of their meaning, presenting a significant challenge in deciphering these ancient texts. With the advent of Artificial Intelligence (AI), employing AI to assist in interp…

The sounds of science a symphony for many instruments and voices part II
Despite its amazing quantitative successes and contributions to revolutionary technologies, physics currently faces many unsolved mysteries ranging from the meaning of quantum mechanics to the nature of the dark energy that will determine the future of the Universe. It is clearly prohibitive for the general reader, and even the best informed physicists, to follow the vast number of technical papers published in the thousands of specialized journals. For this reason, we have asked the leading ex…

Fossil and present-day stromatolite ooids contain a meteoritic polymer of glycine and iron
Hemoglycin, a space polymer of glycine and iron, has been identified in the carbonaceous chondritic meteorites Allende, Acfer 086, Kaba, Sutters Mill and Orgueil. Its core form has a mass of 1494Da and is basically an antiparallel pair of polyglycine strands linked at each end by an iron atom. The polymer forms two- and three- dimensional lattices with an inter-vertex distance of 4.9nm. Here the extraction technique for meteorites is applied to a 2.1Gya fossil stromatolite to reveal the presenc…
