Fine-Grained HDR Image Quality Assessment From Noticeably Distorted to Very High Fidelity
High dynamic range (HDR) and wide color gamut (WCG) technologies significantly improve color reproduction compared to standard dynamic range (SDR) and standard color gamuts, resulting in more accurate, richer, and more immersive images. However, HDR increases data demands, posing challenges for bandwidth efficiency and compression techniques. Advances in compression and display technologies require more precise image quality assessment, particularly in the high-fidelity range where perceptual…

Extended Version of Paper Presented at ICISSP, Porto 20-22 February, 2025 A Value-Driven Approach to the Online Consent Conundrum -- A Study with the Unemployed
Online services are required to gain informed consent from users to collect, store and analyse their personal data, both intentionally divulged and derived during their use of the service. There are many issues with these forms: they are too long, too complex and demand the user's attention too frequently. Many users consent without reading so do not know what they are agreeing to. As such,granted consent is effectively uninformed. In this paper, we report on two studies we carried out to arriv…

Accuracy of analytic potentials for orbits of satellites around a Milky Way-like galaxy: comparison with $N$-body simulations
To study the orbits of satellites, a galaxy could be modelled either by means of a static gravitational potential, or by live $N$-body particles. Analytic potentials allow for fast calculations, but are idealized and non-responsive. On the other hand, $N$-body simulations are more realistic, but demand higher computational cost. Our goal is to characterize the regimes in which analytic potentials provide a sufficient approximation, and those where $N$-bodies are necessary. We perform two sets o…

YSO Jets Driven by Magnetic Pressure Generated through Stellar Magnetosphere-Disk Interaction
The origin of jets in young stellar objects (YSOs) remains a subject of active investigation. We present a 3D non-ideal magnetohydrodynamic simulation of jet launching in YSOs, focusing on the interaction between the stellar magnetosphere and the circumstellar disk. At the beginning of the simulation, the magnetosphere partially opens, forming two oppositely directed magnetic field regions: one threading the star and the other threading the inner disk. The latter dominates over the original dis…

JT de Sitter Gravity as a Model of Coleman-de Luccia Tunneling

JT de Sitter Gravity as a Model of Coleman-de Luccia Tunneling
We interpret the Euclidean solution of JT de Sitter gravity as the Coleman-de Luccia instanton for the decay of the low-entropy horizon of its static patch solution into either a Big Crunch or an infinite-entropy Lorentzian de Sitter cosmology. As in previous work by one of the authors, the Big Crunch is interpreted as bounding the entropy of the static state. The principle of detailed balance then guarantees it will transition back to a higher entropy causal diamond in the expanding cosmology.…

"The cult of goal-setting thrives in this illusion. It converts uncertainty into an illusion of progress. It demands specificity in exchange for comfort. And it replaces self-trust with the performance of future-planning."

Smart People Don't Chase Goals; They Create Limits
A few years ago, I sat across from a friend at a late dinner. He was telling me about his new promotion, the big title, the bonus, the corner office. I remember watching his face as he described it. He looked like someone describing a story he’d once believed
