Ultrafast fMRI Detects Age‐Related Changes in Harmonics of Cardiac Pulsations in the Brain at 7 T

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Aging impacts pulsatility of blood vessels in the brain, reflecting vascular health. Resolving characteristics of cardiac pulsatility requires faster acquisitions than traditional fMRI. An ultrafast fMRI method was developed and applied to sample several harmonics of cardiac pulsations at 7 T.

A review of high nature value farming systems in Europe: Biodiversity, ecosystem services, drivers, innovations and future prospects

open access: yesPeople and Nature, EarlyView.
Abstract Farming systems of high natural and cultural value represent approximately 30% of farmlands in the European Union and are associated with a high species and habitat diversity and/or the presence of species of European conservation concern. This study aims to synthesize the existing knowledge on the assessment of biodiversity and ecosystem ...

Linking perceptions of weeds with approaches to weed management

open access: yesPeople and Nature, EarlyView.
Abstract A multitude of factors can shape people's perceptions, leading to a variety of views on nature's services and values. The IPBES Values Framework highlights the ways that people and nature interact (both positively and negatively) through consideration of nature's contributions to people. For plants, differences in perceived values by different

Effects of Engineered Dam Releases on Benthic Assemblages During Drought and Comparison With Unregulated Reaches

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT River regulation following damming is often associated with deleterious downstream effects, in large part due to reduced total discharge and disruption of seasonal flooding. These effects would be expected to be exacerbated by drought, particularly extended drought.

Beggars as Rational Choosers

open access: yesSouthern Economic Journal, EarlyView.
ABSTRACT American municipalities increasingly regulate panhandling. That regulation is controversial. The determinants of panhandling activeness are unknown, and it is doubted whether panhandling activity responds rationally to incentives. To shed light on these issues, we collect data on hundreds of panhandlers and the passersby they solicit at ...

Performing Integrity: Managing Misalignment while Researching Transgressive Social Worlds

open access: yesSymbolic Interaction, EarlyView.
The qualitative literature criticizing REBs suggests that researchers should develop an approach to research ethics that does justice to their daily practice of fieldwork. In this article, I contribute to this exploration by presenting three cases of negotiating research ethics while researching transgressive social worlds.

From prediction to intervention: Paradigm shifts in causal AI for precision medicine and large‐scale cohorts

open access: yesVIEW, EarlyView.
Large‐scale cohorts and multimodal biomedical data have enabled powerful predictive models for clinical risk stratification, but prediction alone cannot guide effective interventions. This review introduces causal artificial intelligence as a design‐first framework that integrates target trial emulation, causal discovery, and robust effect estimation ...

Posidonia oceanica Leaves as a Natural Filler for Poly(Butylene Succinate‐Co‐Adipate) Composites: Characterization and Biodegradation Assessment in Seawater

open access: yesJournal of Vinyl and Additive Technology, EarlyView.
This study shows that incorporating 5–10 wt.% Posidonia oceanica, with or without micro‐talc, in PBSA preserves thermal stability, modifying crystallization behavior, and maintains good filler dispersion and interfacial adhesion. Mechanical properties are moderately stiffened.
