Tootfinder

Every night recently, I’ve been woken up by ‘something’ just before 3am
The novelty has officially worn off

Measurement of the photometric Baryon Acoustic Oscillations with self-calibrated redshift distribution
We use a galaxy sample derived from the DECaLS DR9 to measure the Baryonic Acoustic Oscillations (BAO). The magnitude-limited sample consists of 10.6 million galaxies in an area of 4974 deg$^2$ over the redshift range of [0.6, 1]. A key novelty of this work is that the true redshift distribution of the photo-$z$ sample is derived from the self calibration method, which determines the true redshift distribution using the clustering information of the photometric data alone. Through the angular c…

Today is the seventh anniversary of political analyst Robert E Kelly being interviewed by the BBC about North Korea when his then-four-year-old daughter barged into the room with her baby brother following. A novelty in 2017, many of us experienced a variation of that scene in our own lives during the years following 2020. BBC interview Dad was simply ahead of the times.

Novelty Detection on Radio Astronomy Data using Signatures
We introduce SigNova, a new semi-supervised framework for detecting anomalies in streamed data. While our initial examples focus on detecting radio-frequency interference (RFI) in digitized signals within the field of radio astronomy, it is important to note that SigNova's applicability extends to any type of streamed data. The framework comprises three primary components. Firstly, we use the signature transform to extract a canonical collection of summary statistics from observational sequence…

G$ \mathbf{^2} $VD Planner: Efficient Motion Planning With Grid-based Generalized Voronoi Diagrams
In this paper, an efficient motion planning approach with grid-based generalized Voronoi diagrams (G$ \mathbf{^2} $VD) is newly proposed for mobile robots. Different from existing approaches, the novelty of this work is twofold: 1) a new state lattice-based path searching approach is proposed, in which the search space is reduced to a novel Voronoi corridor to further improve the search efficiency; 2) an efficient quadratic programming-based path smoothing approach is presented, wherein the cle…

Extreme Noise Terror - “Conned Through Life” (1988)
This compilation was my introduction to the wild world of “grindcore” music.
This musical genre is more of a novelty to me. I listen only occasionally.
But it’s classic John Peel.
He invited a succession of then unknown, extreme hardcore metal bands to play live on his national radio show. I’ve read that these shows drew a few more listener complaints than usual, as listeners were aurally assaulted by the most ext…
