Association of Glucagon‐Like Peptide‐1 Receptor Agonists With Cancer Risk in Older Adults With Type 2 Diabetes

open access: yesObesity, EarlyView.
ABSTRACT Objective The real‐world evidence on the association between glucagon‐like peptide‐1 receptor agonists (GLP‐1RAs) and cancer risk remains limited and mixed. Methods In 2013–2020 national Medicare claims data, we included cancer‐naïve patients with type 2 diabetes (T2D). We identified those who initiated GLP‐1 RA, sodium‐glucose cotransporter 2

A deterministic optimal design problem for the heat equation [PDF]

open access: yes, 2016
For the heat equation on a bounded subdomain $\Omega$ of $\mathbb{R}^d$, we investigate the optimal shape and location of the observation domain in observability inequalites.

What does coexistence mean? Insight from place‐based trajectories of pastoralists and bears encounters in the Pyrenees

open access: yesPeople and Nature, EarlyView.
Abstract The recovery of large carnivores in Europe raises issues related to sharing landscape with humans. Beyond technical solutions, it is widely recognized that social factors also contribute to shaping coexistence. In this context, scholars increasingly stress the need to adopt place‐based approaches by analysing how humans and wildlife interact ...

A uracil nitroso amine based colorimetric sensor for the detection of Cu²⁺ ions from aqueous environment and its practical applications [PDF]

open access: yes, 2015
A simple uracil nitroso amine based colorimetric chemosensor (UNA-1) has been synthesized and screened for its cation recognition ability. Sensor UNA-1 exhibited a high sensitivity and selectivity towards Cu²⁺ ions in aqueous medium in the presence of a ...

Electrified rhythms: How hydropower infrastructure transforms hydrosocial relations of riverine communities in the Lower Sogamoso River, Colombia

open access: yesPeople and Nature, EarlyView.
Abstract Hydropower dams regulate water flows for millions of downstream inhabitants worldwide, altering water availability. Under a changing climate, flow control is often framed technically and politically as being essential for reducing drought and flood risks. However, it can also disrupt ecological flows, impact livelihoods and erode environmental

Tannins in Baccharis dracunculifolia (Asteraceae): effects of seasonality, water availability and plant sex Taninos em Baccharis dracunculifolia (Asteraceae): efeitos da sazonalidade, disponibilidade de água e sexo da planta

open access: yesActa Botânica Brasílica, 1999
Several ecological, genetic, and environmental factors are known to influence tannin concentration in plant tissues. In this study, the effects of seasonality, water availability, and sex of the plant on tannin concentration in the dioecious shrub ...

Hybrid Force Control with on/off Electropneumatic Standard Distributors [PDF]

open access: yesInternational Journal of Fluid Power, 2006
This paper presents a new control method applied to the electro-pneumatic field. This strategy originates from the hybrid control theory recently developed for the control of asynchronous or synchronous electrical motors, e.g. Retif (2004). The interest of this strategy concerns the possibility of using standard on/off distributors instead of the usual
