Environmental, bystander and resident exposure from orchard applications using an agricultural unmanned aerial spraying system.

Unmanned aerial spraying systems (UASS), i.e., unmanned aerial vehicles designed for pesticide applications, are widely used in East Asia and increasingly prevalent in other regions of the world, including North America and Europe.

MGMT inactivation as a new biomarker in patients with advanced biliary tract cancers.

Biliary tract cancers (BTCs) have poor prognosis and limited therapeutic options. The impact of O -methylguanine-DNA methyltransferase (MGMT) inactivation in advanced BTC patients is not established. We investigated the prevalence, prognostic, and predictive impact of MGMT inactivation in two multicenter cohorts.

Communication, continuity and coordination of care are the most important patients' values for family medicine in a fee-for-services health system.

Background: Representing 60% of medical consultations in Switzerland, primary care holds an important place in our medical system. Patients' values in family medicine (FM) are nowadays recognized as important factors to take into account in order to provide good quality of care. The aim of this study is to describe patients' most important values regarding FM and to assess their associations with socio-demographics factors in a fee-for-services health system.

Model of annual plants dynamics with facilitation and competition.

An individual-based model describing the dynamics of one type of annual plants is presented. We use Monte Carlo simulations where each plant has its own history and the interactions among plants are between nearest neighbours. The character of the interaction (positive or negative) depends on local conditions.
