Iyo vs. Io — OpenAI and Jony Ive get sued
In May, legendary Apple designer Jony Ive hooked up with OpenAI to announce an unspecified gadget. [WSJ, archive] To promote this complete vaporware, OpenAI released a video of Sam Altman and Ive b…

Gravitational-Wave Background from Extragalactic Double White Dwarfs for LISA
Recent studies have revealed the contribution of extragalactic DWD to the astrophysical SGWB could be detectable in the mHz regime by LISA. Conversely, the presence of this SGWB could hamper the detection of cosmological SGWB, which are one of the key targets of GW astronomy. We aim to confirm the spectrum of the extragalactic DWD SGWB and estimate its detectability with LISA under different assumptions. We also aim at understanding the main uncertainties in the spectrum and estimate if the sig…

#ndwgoecountdown Vortrag – Wie alt ist eigentlich der Mond?
Wer verrät schon gerne seine Alter? Der Mond jedenfalls nicht! Seit Langem bemühen sich Forschende, die Geburtsstunde unseres kosmischen Begleiters zu bestimmen. Wichtigster Anhaltspunkt: Mondgestein, von Apollo-Astronauten zurück zur Erde gebracht. Der Vortrag von Prof. Kleine gibt einen Überblick über den aktuellen …

Calamus 38 Primeval my love for the woman I love
Finally a love poem with a female subject! Or is it?
Primeval my love for the woman I love,
It starts off obviously heterosexual, his love for a woman. But then most of the poem is about another love, for "O man", "the last athletic reality". It sounds like he's elevating the love of this other man to "the ethereal", something more spiritual in contrast to the primeval of the first line. But in the context of the rest of Calamus maybe he's saying more about that love for this athletic man, the "sharer of my roving life".
Edit: the Calamus Project reading suggests an extra meaning of "sharer of my roving life". It sounds like Whitman is stepping out on his wife, "roving" with a man on the side.

The Quantum Wave Function as a Complex Probability Distribution
This paper suggests an interpretation for the wave function, based on some elements of Nelson's stochastic mechanics, the time-symmetric laws of quantum theory and complex probabilities. Our main purpose is to demonstrate that the wave function and its complex conjugate can be interpreted as complex probability densities (or quasi-probability distributions) related to non-real forward and backward in time stochastic motion respectively. Those two quasi-Brownian motions serve as mathematical abs…

Disturbing news about the $d=2+ε$ expansion
The $O(N)$ Non-Linear Sigma Model (NLSM) in $d=2+ε$ has long been conjectured to describe the same conformal field theory (CFT) as the Wilson-Fisher (WF) $O(N)$ fixed point obtained from the $λ(ϕ^2)^2$ model in $d=4-ε$. In this work, we put this conjecture into question, building on the recent observation [Jones (2024)] that the NLSM CFT possesses a protected operator with dimension $N-1$, which is instead absent in the WF $O(N)$ CFT. For $N=3$, we investigate the possibility of lifting thi…

Temporally Extending Existing Web Archive Collections for Longitudinal Analysis
The Environmental Governance and Data Initiative (EDGI) regularly crawled US federal environmental websites between 2016 and 2020 to capture changes between two presidential administrations. However, because it does not include the previous administration ending in 2008, the collection is unsuitable for answering our research question, Were the website terms deleted by the Trump administration (2017--2021) added by the Obama administration (2009--2017)? Thus, like many researchers using the Way…
