The Nocturnity Scale: Measuring the Sense of Being at Night in Virtual Urban Environments

Anthony Le Gourri{é}rec, Etienne Peillard, Nicolas Houel +1

Nighttime environments are increasingly used in virtual urban studies, yet darkness alone does not fully recreate the subjective sense of being at night. Prior work suggests that t…

Joint Reconstruction of Activity and Attenuation in PET by Diffusion Posterior Sampling in Wavelet Coefficient Space

Clémentine Phung-Ngoc, Alexandre Bousse, Antoine De Paepe +6

Attenuation correction (AC) is necessary for accurate activity quantification in positron emission tomography (PET). Conventional reconstruction methods typically rely on attenuati…

Robustness to Sparse Adversarial Corruption in Arbitrary Linear Measurements: Beyond Exact Recovery

Vishal Halder, Alexandre Reiffers-Masson, Abdeldjalil Aïssa-El-Bey +1

Recovery from linear measurements under sparse adversarial corruption is typically formulated as an exact-recovery problem: one seeks structural conditions on (e.g., r…

Stochastic dynamics at the back of a gene drive eradication wave

Léna Kläy, Léo Girardin, Florence Débarre +1

Gene drive alleles bias their own inheritance to offspring. They can fix in a wild-type population in spite of a fitness cost, and even lead to the eradication of the target popula…

Free-Space CV-QKD with Single-Mode Fiber Reception: Effective Coupling Statistics and Protocol-Dependent Reference Noise

Hesham S. Ibrahim, Arnaud Coatanhay

We study free-space continuous-variable quantum key distribution (CV-QKD) with single-mode fiber (SMF) reception under atmospheric turbulence. The optical channel is modeled by spl…
