Time‐Division Multiplexing for Parallel Transmission at Ultra‐High Field With Limited RF Channels
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose Investigating time‐division multiplexing for parallel transmission in ultra high‐field imaging, striving for homogeneous whole brain excitation with a limited number of RF channels. Methods A fast RF switch was built to alternately route 8 transmit channels to each row of a double‐row 16‐element transmit coil array at a 9.4 T human MRI

People and Nature, EarlyView.Abstract While the return of wolves (Canis lupus) to many European countries is a conservation milestone, the negative impacts are unevenly distributed across society, placing high pressure on livestock grazing systems. For this perspective, scientists from diverse disciplines and geographical backgrounds reflect on the state of livestock–wolf ...

Cultivating biodiversity: When conservation in agricultural landscapes embodies farmers' values
People and Nature, EarlyView.Abstract Efforts to conserve biodiversity in agricultural landscapes across Europe remain insufficient, as biodiversity further declines. This is sometimes ascribed to conservation policy failing to address the meanings and values that farmers attribute to the social and ecological contexts shaping their decisions influencing biodiversity.

People and Nature, EarlyView.Abstract Volunteers have been involved in nature observations for decades through citizen science initiatives, providing large data sets as well as problem identification that allow a more complete understanding of many natural phenomena. Although communication is a core component in citizen science, the key factors that determine its effectiveness in ...

Die Arktis bei 2,7 Grad globaler Erwärmung: Schwindende Landschaften
Physik in unserer Zeit, EarlyView.Eine dicke Eisschicht auf dem Ozean, hunderte Meter tief gefrorener Boden und ein über 3 000 m hoher Eisschild – diese einzigartige Landschaft wird es vermutlich so in Zukunft nicht mehr geben. Eine globale Erwärmung von 2,7 °C, auf die wir aktuell zusteuern, würde die Arktis bis zur Unkenntlichkeit verändern.

Proteins: Structure, Function, and Bioinformatics, EarlyView.ABSTRACT Anaerobic ammonium‐oxidizing (anammox) bacteria employ a unique, hydrazine‐based pathway to obtain energy from nitrite and ammonium. These organisms possess distinct Rieske/cytochrome b complexes whose precise role in anammox metabolism remains unclear, but which have been proposed to include the generation of NAD(P)H.

Pest Management Science, EarlyView.The flea beetle's glucosinolate‐based chemical defense fails to protect larvae from nematode infection. However, the defense inhibits the nematode's symbiotic bacteria, thereby potentially impairing nematode reproduction and biocontrol success. Abstract BACKGROUND The efficacy of entomopathogenic nematodes (EPNs) in the biological control of insect ...

physica status solidi (b), EarlyView.Nonlocal (NL) electrical measurements in the topological insulator BiSbTeSe2 reveal spin‐polarized surface currents, which vanish around 20 K due to increased interactions between bulk and surface states. An enhanced spin‐to‐background ratio in the NL geometry compared to the local geometry provides new insights into spin transport and current pathways
