Multivariate and Multiple Contrast Testing in General Covariate-adjusted Factorial Designs
Evaluating intervention effects on multiple outcomes is a central research goal in a wide range of quantitative sciences. It is thereby common to compare interventions among each other and with a control across several, potentially highly correlated, outcome variables. In this context, researchers are interested in identifying effects at both, the global level (across all outcome variables) and the local level (for specific variables). At the same time, potential confounding must be accounted f…

Data Verbalisation: What is Text Doing in a Data Visualisation?
This article discusses the role that text elements play in a data visualisation. We argue that there is a need for a simple, coherent explanation of text elements similar to the understanding that already exists for non-text elements like bars, points, and lines. We explore examples of how text is used within a data visualisation and use existing knowledge and assessment techniques to evaluate when text is effective and when it is not. The result is a framework that aims to be easy to understan…

Rotational Variables: Kepler Versus ASAS-SN
Rotational variables are stars that vary in brightness due to star spots modulated by rotation. They are probes of stellar magnetism, binarity, and evolution. Phillips et al. (2023) explored distinct populations of ~50,000 high-amplitude rotational variables from the All-Sky Automated Survey for Supernovae (ASAS-SN), examining correlations between stellar rotation, binarity, and activity. Here, we carry out a similar analysis of ~50,000 much lower amplitude Kepler rotational variables. The Kepl…

Das verbleibende #CO2Budget für das 1,5-Grad-Ziel ist fast aufgebraucht.
Aktuell bleiben der Menschheit laut neuem Bericht nur noch rund drei Jahre, bevor das Begrenzungsziel aus dem Pariser Abkommen endgültig gebrochen wird.

CO₂-Budget: In drei Jahren bricht die Welt endgültig ihr 1,5-Grad-Versprechen
Das CO₂-Budget für 1,5 Grad schmilzt rapide. Ein Update des Weltklimarates zeigt: Wenn die Emissionen nicht sofort sinken, ist das Ziel in drei Jahren außer Reichweite.

Using Real-Variable Techniques to Study Zeros of Complex-Valued Harmonic Functions
We investigate the zeros of two one-parameter families of harmonic functions and describe how the number of zeros depends on the parameter. Our functions have the property that all zeros lie on certain rays in the complex plane and thus we are able to use real-variable techniques to count the zeros on each ray.

Adaptive random compiler for Hamiltonian simulation
Randomized compilation protocols have recently attracted attention as alternatives to traditional deterministic Trotter-Suzuki methods, potentially reducing circuit depth and resource overhead. These protocols determine gate application probabilities based on the strengths of Hamiltonian terms, as measured by the trace norm. However, relying solely on the trace norm to define sampling distributions may not be optimal, especially for continuous-variable and hybrid-variable systems involving unbo…

I grumble a lot about Terraform, but I am very impressed by their error messages.
Something I noticed today: when you get an error in evaluation, it also prints any local variables in the expression that led to the error, so you can more easily figure out what went wrong.
