AI won’t save PDF from itself. PDFs are largely inaccessible, proprietary, and a nightmare for data extraction (ever tried copy-pasting a two-column doc?). Mistral’s new tool still struggles to convert them cleanly; imagine misreading a PDF drug chart and prescribing a 500mg overdose instead of 50mg. Science is about reusing knowledge, so it's high time we used formats that make it easy to extract data—rather than consign it to a tomb

Equivariant CM minimization for extremal manifolds
We prove an equivariant version of the CM minimization conjecture for extremal Kähler manifolds. This involves proving that, given an equivariant punctured family of polarized varieties, a relative version of the CM degree is strictly minimized by an extremal filling. This generalizes a result by Hattori for cscK manifolds with discrete automorphism group by allowing automorphisms and extremal metrics. As a main tool, we extend results by Székelyhidi on asymptotic filtration Chow stability …

Incorporating Linguistic Constraints from External Knowledge Source for Audio-Visual Target Speech Extraction
Audio-visual target speaker extraction (AV-TSE) models primarily rely on target visual cues to isolate the target speaker's voice from others. We know that humans leverage linguistic knowledge, such as syntax and semantics, to support speech perception. Inspired by this, we explore the potential of pre-trained speech-language models (PSLMs) and pre-trained language models (PLMs) as auxiliary knowledge sources for AV-TSE. In this study, we propose incorporating the linguistic constraints from PS…

A Berny green, flieger - type b style watch, with a green dial.
Yes, it looks similar to a certain Seiko with this dial color and the four o'clock crown but, that watch too steals 90 % of it's design from classic fliegers, so I'm ok with it. 😆
Plus it has a couple of things extra I wanted. Titanium case, sapphire crystal, no logo or extraneous text on the face (like classic fliegers) and it features a "mecha-quartz" (quartz accuracy but the second hand is m…

Bipartite entanglement extracted from multimode squeezed light generated in lossy waveguides
Entangled two-mode Gaussian states constitute an important building block for continuous variable quantum computing and communication protocols and are thus of high demand for many experiments. In this work, we study such kind of states which are extracted from multimode light generated via type-II parametric down-conversion (PDC) in lossy waveguides. For such states, we demonstrate that the squeezing quantifies entanglement and we construct a measurement basis which results in the maximal bipa…

Power Diagram Enhanced Adaptive Isosurface Extraction from Signed Distance Fields
Extracting high-fidelity mesh surfaces from Signed Distance Fields has become a fundamental operation in geometry processing. Despite significant progress over the past decades, key challenges remain namely, how to automatically capture the intricate geometric and topological structures encoded in the zero level set of SDFs. In this paper, we present a novel isosurface extraction algorithm that introduces two key innovations: 1. An incrementally constructed power diagram through the addition of…
