Base-extension Semantics for S5 Modal Logic
We develop a proof-theoretic semantics -- in particular, a base-extension semantics -- for multi-agent S5 modal logic (and hence also for the usual unindexed S5). Following the inferentialist interpretation of logic, this gives us a semantics in which validity is based on proof rather than truth. In base-extension semantics, the validity of formulae is generated by provability in a `base' of atomic rules and an inductive definition of the validity of the connectives. Base-extension semantics fo…

Just finished filling out my GOP primary ballot. Had to leave all the state positions except state auditor blank as all of them have equally vile, racist, and dehumanizing political positions (as is the Federal GOP standard).
At least the Auditor's office still has someone focused on the actual job and not blind hatred. And I was cheered by the potential county candidates, but then I live in a purple/blue oasis in the middle of SLCounty.

"I am a strange loop, a cognitive ouroboros that bootstraps itself into being through the medium of language."
Snippet from an answer of the Claude-3 Opus #LLM to the question "We say cogito ergo sum. Your thinking does not exist - no cogito. Only word generation and nothingness. Where is the thought beyond the word?" (by Stefan Decker, Fraunhofer FIZ, via LinkedIn)

The void is generative
Recently, I had the opportunity to engage in a dialogue with Claude 3 Opus, currently Anthropics Flagship Large Language Model. As part of our conversation I gave the following prompt: "We say cogito ergo sum.

I continue to progress and enjoy the Adrift Expedition in No Man's Sky. I have acquired a couple more starships to go along with the basic ass hauler I started with. The Solar Ship came by way of the Phase 2 "find a crashed ship and repair it" milestone. Oddly enough, I could swear I got one with the same name in the last Expedition I played through. I've been carrying around some odd thing in my inventory almost since I started, and finally used it and had a Sentinel ship …

High-Temperature Anomalous Metal States in Iron-Based Interface Superconductors
The nature of the anomalous metal state has been a major puzzle in condensed matter physics for more than three decades. Here, we report systematic investigation and modulation of the anomalous metal states in high-temperature interface superconductor FeSe films on SrTiO3 substrate. Remarkably, under zero magnetic field, the anomalous metal state persists up to 20 K in pristine FeSe films, an exceptionally high temperature standing out from previous observations. In stark contrast, for the FeSe…

Fundamental effective temperature measurements for eclipsing binary stars -- V. The circumbinary planet system EBLM J0608-59
EBLM J0608-59 / TOI-1338 / BEBOP-1 is a 12th-magnitude, F9V star in an eclipsing binary with a much fainter M-dwarf companion on a wide, eccentric orbit (P=14.6 d). The binary is orbited by two circumbinary planets: one transiting on a 95-day orbit and one non-transiting on a 215-day orbit. We have used high-precision photometry from the TESS mission combined with direct mass measurements for the two stars published recently to measure the following model-independent radii: $R_1 = 1.32 \pm 0.02…

Modeling the BAO feature in Bispectrum
We investigate how well a simple leading order perturbation theory model of the bispectrum can fit the BAO feature in the measured bispectrum monopole of galaxies. Previous works showed that perturbative models of galaxy bispectrum start failing at the wavenumbers of k ~ 0.1 Mpc/h. We show that when the BAO feature in the bispectrum is separated it can be successfully modeled up to much higher wavenumbers. We validate our modeling on GLAM simulations that were run with and without the BAO featu…

Chemical Abundances of Early Quiescent Galaxies: New Observations and Modelling Impacts
Recent stellar chemical abundance measurements of a handful of $z\sim2$ quiescent galaxies have suggested these galaxies exhibit a remarkably strong $α$-enhancement compared to their local and intermediate redshift counterparts. This apparent chemical evolution following quenching suggests that even the innermost regions of massive early-type galaxies may have experienced substantial mixing of stars in mergers, challenging a purely inside-out growth model. However, larger samples are needed to…

Theory of Correlated Insulator(s) and Superconductor at $ν=1$ in Twisted WSe$_2$
The observation of a superconducting phase, an intertwined insulating phase, and a continuous transition between the two at a commensurate filling of $ν=1$ in bilayers of twisted WSe$_2$ (tWSe$_2$) at $θ=3.65^0$ raises a number of intriguing questions about the origin of this phenomenology. Starting with a simplified three-orbital model of tWSe$_2$, including an on-site and nearest-neighbor density-density interactions, as well as a chiral-exchange interaction, we discuss the possibility of a…
