To cross or not to cross, that's the question...
(One of the more intense streams — the outflow of a glacier — I had to cross in my life, that bridge looks a lot safer that it was IRL...)

The Hybrid Euclidean-Lorentzian Universe: Stability Considerations and the Point of Transition
TThe limited velocity implied by Lorentzian signature, prevents the universe to reach thermodynamic equilibrium implied by the CMB. Rapid expansion can occur by following Hawking and assuming a primordial Euclidean metric, in which case velocity is not limited and thermalization and rapid expansion are derived without the need to assume an ad-hoc field. Moreover, a mathematical model was given regarding the development of current Lorentzian space-time from the early Euclidean space-time in whic…

What, my family actually expects me to act "normal"? What kind of backwards sorcery is that? I’m an anarchist at heart and a syndicalist by choice, no apologies, no compromises.

RationalVLA: A Rational Vision-Language-Action Model with Dual System
A fundamental requirement for real-world robotic deployment is the ability to understand and respond to natural language instructions. Existing language-conditioned manipulation tasks typically assume that instructions are perfectly aligned with the environment. This assumption limits robustness and generalization in realistic scenarios where instructions may be ambiguous, irrelevant, or infeasible. To address this problem, we introduce RAtional MAnipulation (RAMA), a new benchmark that challen…

Exocomets of $β$ Pictoris I: Exocomet destruction, sodium and disk line variability in 17 years of HARPS observations
The young $β$ Pictoris system has been monitored with high-resolution optical spectrographs for decades. These observations have revealed strongly variable absorption in the Ca II H\&K lines attributed to in-falling cometary bodies. Since 2003, over 9000 HARPS observations of $β$ Pictoris have been taken and many of these have not yet been used for exocomet studies. We search these spectra for new exocomet phenomenology enabled by the long time coverage and large volume of this dataset. We sy…
