Stable amalgamation over a predicate and the Gaifman property
We consider the following property of a first order theory T with a distinguished unary predicate P: every model of the theory of P occurs as the P-part of some model of T. We call this property the Gaifman property. Gaifman conjectured that if T is relatively categorical over P, then it has the Gaifman property. We propose a generalized version of this conjecture: if T fails the Gaifman property, then it exhibits non-structure over P, i.e., has many non-isomorphic models over P in many cardina…

Having nothing to do with current events, might I suggest reading my “children’s story” Winnie the Coup and Elongated Muskrat Bulldoze the Gubment tonight before bed?

Winnie the Coup and the Elongated Muskrat Bulldoze the Gubment
Once upon a time, there was an orange creature named Winnie the Coup and he had what he thought was a friend, the Elongated Muskrat. Muskrat had a lot of toys and Winnie the Coup was sorta jealous…

Circular dichroism in the photoelectron angular distribution of achiral molecules
Circular dichroism in the angular distribution (CDAD) is the effect that the angular intensity distribution of photoemitted electrons depends on the handedness of the incident circularly polarized light. A CDAD may arise from intrinsic material properties like chirality, spin-orbit interaction, or quantum-geometrical effects on the electronic structure. In addition, CDAD has also been reported for achiral organic molecules at the interface to metallic substrates. For this latter case, we invest…

Olha, Portugal ali em primeiro.
Curioso que quando nos ensinam na escola os descobrimentos nem sempre nos digam também que "descobrimentos" sempre implicaram imperialismo e colonialismo e o que deles vem.
Em grande medida, Portugal criou o mundo moderno. Com o que isso tem de bom E com o (muito) que tem de mau. Mas por cš raramente se fala do mau.

Measurement of photo- and radio-luminescence of thin ThF4 films
We conducted measurements on the photo- and radio-luminescence of thin ThF$_4$ films in both the UV and visible ranges. In the UV range, we found that both luminescences are at a similar level as the internal dark counting noise of the photo-multiplier-tube (PMT). Our results suggest that thin ThF$_4$ crystals could be used as a target for the search for $^{229m}$Th and as a medium for the future nuclear clock. The measurements indicate that using a small and thin ThF$_4$ film can reduce backgr…

GPUnion: Autonomous GPU Sharing on Campus
A pronounced imbalance in GPU resources exists on campus, where some laboratories own underutilized servers while others lack the compute needed for AI research. GPU sharing can alleviate this disparity, while existing platforms typically rely on centralized oversight and persistent allocation models, conflicting with the voluntary and autonomous nature of academic resource ownership. We present GPUnion, a campus-scale GPU sharing platform enabling voluntary participation while preserving full …

BecomingLit: Relightable Gaussian Avatars with Hybrid Neural Shading
We introduce BecomingLit, a novel method for reconstructing relightable, high-resolution head avatars that can be rendered from novel viewpoints at interactive rates. Therefore, we propose a new low-cost light stage capture setup, tailored specifically towards capturing faces. Using this setup, we collect a novel dataset consisting of diverse multi-view sequences of numerous subjects under varying illumination conditions and facial expressions. By leveraging our new dataset, we introduce a new …
