Optimization of Parallel Artificial Liquid Membrane Extraction for the Determination of Over 50 Psychoactive Substances in Oral Fluid Through UHPLC–MS/MS

Drug Testing and Analysis, EarlyView.
This study is related to the development of a microextraction method for the determination of 56 psychoactive substances in oral fluid. Sample clean‐up is obtained by parallel artificial liquid membrane extraction and analyzed by liquid chromatography–tandem mass spectrometry.

Trade‐offs among restored ecosystem functions are context‐dependent in Mediterranean‐type regions

Ecography, EarlyView.
Global biodiversity hotspots, including Mediterranean‐type ecosystems worldwide, are highly threatened by global change that alters biodiversity, ecosystem functions, and services. Some restoration activities enhance ecosystem functions by reintroducing plant species based on known relationships between plant traits and ecosystem processes.

Evolutionary trajectories of multiple defense traits across phylogenetic and geographic scales in Vitis

Ecography, EarlyView.
The processes driving defense trait correlations may vary within and between species based on ecological or environmental contexts. However, most studies of plant defense theory fail to address this potential for shifts in trait correlations across scales.

Testing New Physics in Oscillations at a Neutrino Factory [PDF]

arXiv
A neutrino factory is a potential successor to the upcoming generation of neutrino oscillation experiments and a possible precursor to next-generation muon colliders. Such a machine would provide a well characterized beam of $\nu_\mu$, $\bar\nu_\mu$, $\nu_e$, and $\bar\nu_e$ neutrinos with comparable statistics.
