Receiver operating characteristic curve analysis with non‐ignorable missing disease status

Canadian Journal of Statistics, Volume 53, Issue 4, December 2025.
Abstract This article considers the receiver operating characteristic (ROC) curve analysis for medical data with non‐ignorable missingness in the disease status. In the framework of the logistic regression models for both the disease status and the verification status, we first establish the identifiability of model parameters, and then propose a ...

Transfert d'énergie par résonance de type Förster entre des complexes de terbium et des boîtes quantiques pour des immunodosages et des reglettes moléculaires multiplexés [PDF]

, 2015
Förster resonance energy transfer (FRET) is a non-radiative energy transfer from a donor to an acceptor in close proximity. Due to its extremely sensitive distance dependence in the 1 – 20 nm range, FRET plays an important role in nanobiotechnology ...

A precision trial case study for heterogeneous treatment effects in obstructive sleep apnea

Canadian Journal of Statistics, Volume 53, Issue 4, December 2025.
Abstract Precision medicine tailors treatments to individual patient characteristics, which is especially valuable for obstructive sleep apnea (OSA), where treatment responses vary widely. Traditional trials often overlook subgroup differences, leading to suboptimal recommendations.

Clickable Pyclen‐Based Luminescent Lanthanide Complexes: Application to Two‐Photon Microscopy

Chemistry – A European Journal, Volume 31, Issue 48, August 26, 2025.
This work presents two pyclen‐based lanthanide complexes (Eu3+ and Sm3+) bearing an alkynyl‐linker dedicated to bioconjugation. Featuring strong luminescence and two‐photon (2P) absorption, they were conjugated to a cell‐penetrating peptide thanks to copper‐catalyzed azide‐alkyne cycloaddition. The resulting luminescent conjugates reach efficiently the

Understanding the dandruff flare‐up: A cascade of measurable and perceptible changes to scalp health

International Journal of Cosmetic Science, Volume 47, Issue 4, Page 703-717, August 2025.
A summary of the changes that occur as the scalp condition worsens after switching from an anti‐dandruff (AD) shampoo to a cosmetic, non‐AD shampoo. The data, represented as a percent change from those maintaining the use of an AD shampoo, underscores the importance of regular, sustained usage of an AD shampoo to promote optimal scalp health.

Stratigraphie et biomarqueurs

Cahiers François Viète, 2005
La stratigraphie étudie l’agencement des couches sédimentaires dans le but d’établir des corrélations à distance entre elles et de leur attribuer un âge. Elle dispose pour cela de différents types de signaux. Parmi ceux-ci les biomarqueurs que sont les fossiles, témoins d’un processus d’évolution irréversible, ont été depuis longtemps sollicités.

Claw growth rates in a subset of adult, indoor, domestic cats (Felis catus)

Veterinary Dermatology, Volume 36, Issue 3, Page 362-367, June 2025.
Background – Keratinised tissues, such as nails and claws, accumulate hormones over time; the claws' hormone concentrations are being explored as potential biomarkers. Timelines for hormone deposition can be established if claw growth rates are known. Hormone concentration within cat claws has been recently evaluated, yet the growth rates of cat claws ...

A Periodic 4‐h Extension of the Dark Period Did Not Cause Long‐Term Changes in the Circadian Regulation of Photosynthesis and Sugar Levels in Lettuces

Plant Direct, Volume 9, Issue 4, April 2025.
ABSTRACT The photoperiod in controlled environment agriculture can be adjusted to minimize electricity consumption, even if it differs from the plant's circadian rhythm. Daily modifications of the photoperiod disrupt the plant's circadian resonance state, resulting in altered growth and yield.
