Am I the only one who foresees the future #AI business model as enshittified ad-infused LLMs? Once LLMs are ingrained in every class and board room, you‘ll suddenly have to pay big bucks while the free plans will be riddled with ads. It‘ll be like that #BlackMirror episode where the teacher spews comme…

Recent results from MicroBooNE
Modelling and reconstructing neutrino-nucleus scattering is difficult, but it is crucial to do it precisely to enable next-generation oscillation measurements. Liquid argon time projection chambers (LArTPCs), such as MicroBooNE, can be the tool for this job as they are excellent precision neutrino detectors with their ability to produce detailed three-dimensional interaction images and precise energy and spatial resolution. MicroBooNE currently possesses the world's largest neutrino-argon scatt…

Microbiologists discover new species of methane-producing archaea in the human gut
An international team of microbiologists from the Medical University of Graz, the DSMZ—German Collection of Microorganisms and Cell Cultures (Braunschweig, Germany)—and the University of Illinois (U.S.) has identified and described a previously unknown species of methane-producing archaea in the human gut: Methanobrevibacter intestini sp. nov. (strain WWM1085).

A family of non Minkowski measurable fractals in $\mathbb{R}^2$
A long-standing conjecture of Lapidus asserts that, under certain conditions, a self-similar fractal set is not Minkowski measurable if and only if it is of lattice-type. For self-similar sets in $\mathbb{R}$, the Lapidus conjecture has been confirmed. However, in higher dimensions, it remains unclear whether all lattice-type self-similar sets are not Minkowski measurable. This work presents a family of lattice-type subsets in $\mathbb{R}^2$ that are not Minkowski measurable, hence providing fu…

Very cool looking company! Gorgeous microphones, audio geekery. Glad to have them on my radar 🧐 https://musicians.today/@arendleejessurun/114792116804285326

3D-Printed Enclosure Wire-Guided Liquid Microfilm for Versatile Spectroscopy
We present a 3D-printing-based design to produce wire-guided liquid microfilms that can be used for versatile spectroscopic applications. We demonstrate the ability of our instrument to provide optically useful liquid microfilms with highly tunable thicknesses over the range 25 - 180 $μ$m, with standard temporal thickness deviation less than 1.0% on the low end of the range of flow rates, and spatially homogeneous microfilms that remain stable over the course of ten hours. We then show the dev…

Today, I re-printed the first two things I ever designed for #3DPrinting nine years ago and change. When the pen clips for our kitchen whiteboard broke back in 2016, right after I bought my first printer, I made replacements.

Baby's first unun!
My #AmateurRadio journey continues with making some of my own equipment...
I wanted to be able to connect either an EFHW or an EFRW to my KX3, but move the actual antenna away from the radio, so that I can POTA with other people close enough to talk, while keeping the antennas for the different out of each others' near field so they don't interere. To …
