Benchmarking GPT-5 in Radiation Oncology: Measurable Gains, but Persistent Need for Expert Oversight
Introduction: Large language models (LLM) have shown great potential in clinical decision support. GPT-5 is a novel LLM system that has been specifically marketed towards oncology use. Methods: Performance was assessed using two complementary benchmarks: (i) the ACR Radiation Oncology In-Training Examination (TXIT, 2021), comprising 300 multiple-choice items, and (ii) a curated set of 60 authentic radiation oncologic vignettes representing diverse disease sites and treatment indications. For …

Optimally building spanning graphs in semirandom graph processes
The semirandom graph process constructs a graph $G$ in a series of rounds, starting with the empty graph on $n$ vertices. In each round, a player is offered a vertex $v$ chosen uniformly at random, and chooses an edge on $v$ to add to $G$. The player's aim is to make $G$ satisfy some property as quickly as possible. Our interest is in the property that $G$ contain a given $n$-vertex graph $H$ with maximum degree $Δ$. In 2021, Ben-Eliezer, Gishboliner, Hefetz and Krivelevich showed that there i…

A transmission hologram for slitless spectrophotometry on a convergent telescope beam. Optimisation and characterization
This article details the optimisation and the characterisation of the hologram described in a companion paper published in 2021, which showed the superiority of a holographic optical element over a periodic grating as a disperser installed in the path of a converging beam on an on-axis detector (unbent spectrograph) for slitless spectroscopy. In this article, we describe in detail the development and optimisation of the final optical holographic element installed on the spectrograph of the auxi…

Quaking in Soft Granular Particles with Speed-dependent Friction: Effect of Inertia
Our previous numerical simulation [C.-E. Tsai et al., Physical Review Research 6, 023065 (2024)] has shown that, for soft granular particles under quasistatic shearing, incorporating a speed-dependent friction is a necessary condition for reproducing the rate-dependent stick-slip fluctuations that have been found in laboratory experiments [J.-C. Tsai et al., Physical Review Letters 126, 128001 (2021)]. As a continuation, here we employ the simulation at a wide range of driving speeds to examine…

En 2018, un verdict belge semblait enfin mettre fin Š une affaire vieille de 20 ans.
En 2025, certaines indemnisations sont toujours en suspens.
Pendant ce temps, en France, l’enquête OKC/Spatz — rouverte officiellement en 2021 — n’a toujours pas abouti.
Cela interroge :

Perturbative QCD below charm threshold: theory and tensions with $e^ e^-$ data

Perturbative QCD below charm threshold: theory and tensions with $e^+e^-$ data
In this paper we carefully assess the theory prediction for $R(s)$ below charm threshold, $R_{uds}$, and address tensions with the existing data, notably with the 2021 BES-III results. We analyze the uncertainty of the perturbative QCD description in the light of renormalons making use of the large-$β_0$ limit and the renormalon-free gluon-condensate scheme. We provide a reliable estimate of the duality violation contributions; we show they are sizable up to $2.5$~GeV and improve the agreement…

Gravitational Recoil and Suppression of Super Massive Black Hole Seeds in the Early Universe
We investigate the impact of gravitational-wave (GW) recoil on the growth of supermassive black holes (SMBHs) in the early Universe. Forming ~10^9 Msun SMBHs by z ~ 6 is challenging and may require hierarchical mergers of smaller seed black holes. We extend a semi-analytic seed model (Sassano et al. 2021) by explicitly incorporating GW recoil physics. Our model includes: (1) recoil velocity formulae calibrated to numerical relativity for spinning, unequal-mass BH binaries (Campanelli et al. 200…
