Teaching students simple #WebScraping was always quite rewarding. It opens up numerous relevant, real-world data sources that are the foundation for any further analysis. Things already got more complicated with dynamic content loading, but now bot-exclusion-mechanisms make it almost impossible in many cases. Is web scraping for the

I used to link to sections of webpages using anchor links, or have jump links pointing to id tags.
I went back to a page where I've done this in the past, and the page has been entirely rewritten with non-semantic HTML. Class descriptors have random suffixes for CSS rather than providing semantic IDs that can be used as jump links as well as, uhhh, semantic organization of a web page.
There's a lot of bad things from the 1980s and 1990s that I am glad to leave behind, but…

Optimising the MeerKAT Pulsar Timing Array and towards precision pulsar timing with SKA-mid
Pulsar timing arrays (PTAs) are Galactic-scale nanohertz-frequency gravitational wave (GW) detectors. Recently, several PTAs have found evidence for the presence of GWs in their datasets, but none of them have achieved a community-defined definitive (> 5$σ$) detection. Here, we identify limiting noise sources for PTAs and quantify their impact on sensitivity to GWs under different observing and noise modelling strategies. First, we search for intrinsic pulse jitter in a sample of 89 MSPs obser…

Surface Acoustic Wave Gas Sensors: Innovations in Functional Materials, Sensing Dynamics, and Signal Analysis
Surface Acoustic Wave gas sensors have garnered increasing attention as highly sensitive, miniaturized, and wireless compatible platforms for molecular detection. Their unique ability to convert surface perturbations into measurable acoustic shifts makes them ideal for gas sensing across diverse environments. This review synthesizes reported SAW platforms across substrates and modes Rayleigh, SH-SAW, Love links transduction pathways to material choice, and benchmarks performance for key analyte…
