Validation of the UPPS-P Impulsive Behavior Scale and Clinical Correlates of its Scores in French-Speaking Patients Starting a Residential Detoxification Program.

Background: Impulsivity is a multifaceted construct that plays a prominent role in substance use disorder (SUD). The UPPS-P model distinguishes five impulsivity components (positive urgency, negative urgency, lack of perseverance, lack of premeditation, and sensation seeking). This study aimed to explore the structure of the UPPS-P in patients hospitalized for SUDs and to investigate the relationship between the dimensions of impulsivity and clinical variables.

The Elephant in the Room - A Critical Interpretive Synthesis of Older Adults' Sexuality.

Objectives: This study aimed to explore past studies that have focused exclusively on the sexuality of adults older than 65 from a positive public health approach.

Methods: We performed a critical interpretive synthesis, starting with the literature review on sexual behaviors in later life, adding policy documents on aging sexuality, and bringing new perspectives.

Results: Older adults continue to be sexually active.

The effect of heat stress on sugar beet recombination.

Meiotic recombination plays a crucial role in plant breeding through the creation of new allelic combinations. Therefore, lack of recombination in some genomic regions constitutes a constraint for breeding programmes. In sugar beet, one of the major crops in Europe, recombination occurs mainly in the distal portions of the chromosomes, and so the development of simple approaches to change this pattern is of considerable interest for future breeding and genetics.

A global cloud free pixel- based image composite from Sentinel-2 data.

Large-scale land cover classification from satellite imagery is still a challenge due to the big volume of data to be processed, to persistent cloud-cover in cloud-prone areas as well as seasonal artefacts that affect spatial homogeneity. Sentinel-2 times series from Copernicus Earth Observation program offer a great potential for fine scale land cover mapping thanks to high spatial and temporal resolutions, with a decametric resolution and five-day repeat time. However, the selection of best available scenes, their download together with the requirements in terms of storage and computing resources pose restrictions for large-scale land cover mapping.

Chlorophyll content estimation in an open-canopy conifer forest with Sentinel-2A and hyperspectral imagery in the context of forest decline.

With the advent of Sentinel-2, it is now possible to generate large-scale chlorophyll content maps with unprecedented spatial and temporal resolution, suitable for monitoring ecological processes such as vegetative stress and/or decline. However methodological gaps exist for adapting this technology to heterogeneous natural vegetation and for transferring it among vegetation species or plan functional types. In this study, we investigated the use of Sentinel-2A imagery for estimating needle chlorophyll (C) in a sparse pine forest undergoing significant needle loss and tree mortality.
