Script Collapse in Multilingual ASR: Defining and Measuring Script Fidelity Rate

Hanif Rahman · 2026

Word error rate (WER) is the dominant metric for automatic speech recognition, yet it cannot detect a systematic failure mode: models that produce fluent output in the wrong writing system. We define …

Fine-tuning Whisper for Pashto ASR: strategies and scale

Hanif Rahman · 2026

Pashto is absent from Whisper's pre-training corpus despite being one of CommonVoice's largest language collections, leaving off-the-shelf models unusable: all Whisper sizes output Arabic, Dari, or Ur…

A critical analysis of main-sequence fitting in open clusters to derive the helium-to-metal enrichment ratio $\Delta Y/\Delta Z$

G. Valle, N. Ricci, M. Dell'Omodarme, P.G. Prada Moroni, S. Degl'Innocenti, S. Cassisi · 2026

We aim to investigate the feasibility of accurately determining the helium-to-metal enrichment ratio $\Delta Y/\Delta Z$ for open clusters using Gaia DR3 photometry. To test the reliability of this ca…

Cliques in graphs constructed from Strongly Orthogonal Subsets in exceptional root systems

Patrick J. Browne, Padraig O Cathain · 2026

Given a root system $R$, two roots are said to be \emph{strongly orthogonal} if neither their sum nor difference is a root. Gashi defined a family of graphs with vertices labelled by sums of $k$-eleme…

The Last Fingerprint: How Markdown Training Shapes LLM Prose

E. M. Freeburg · 2026

Large language models produce em dashes at varying rates, and the observation that some models "overuse" them has become one of the most widely discussed markers of AI-generated text. Yet no mechanist…

Pseudofiniteness of the Farey Graph

Connor Martinez Lockhart · 2026

We prove that the theory of the Farey graph is pseudofinite by constructing a sequence of finite structures that satisfy increasingly large subsets of its first-order axiomatization. This graph is an …

Strong spectral gap for geometrically finite hyperbolic manifolds

Dubi Kelmer, Osama Khalil, Pratyush Sarkar · 2026

Let $\Gamma < G := \operatorname{SO}(d+1, 1)$ for $d \geq 1$ be a Zariski dense, geometrically finite, discrete subgroup with critical exponent strictly greater than $d/2$. We show that $L^2(\Gamma\ba…
