10.5 T In Vivo Head Imaging With Universal RF Shimming
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose Brain MR imaging at 10.5 T ultra‐high field offers significant improvements in signal‐to‐noise ratio (SNR), but faces challenges with B1+ inhomogeneity. Parallel‐transmission (pTx) can be used to achieve a more uniform RF field distribution, but necessitates the use of B1+ calibration in the region of interest.

Oikos, EarlyView.Seasonality in temperate ecosystems shapes species phenology, influencing interactions and food web structure. Variations in species richness and biomass affect trophic interaction strength, a crucial factor for community stability, which can be assessed through energy fluxes – an essential indicator of ecosystem function.

Organ Medicine, EarlyView.Alzheimer's disease diagnosis relies on costly, invasive positron emission tomography (PET) imaging and cerebrospinal fluid (CSF) analysis, limiting clinical use. This review summarizes a blood‐based biochemical mass spectrometry platform for early Alzheimer's disease (AD) detection, with non‐invasiveness, high sensitivity (fg/mL level), high ...

Polymer Composites, EarlyView.Comparison of experimental and model‐predicted erosion rates for carbon fibre‐reinforced polymer (CFRP) and glass fibre‐reinforced polymer (GFRP) under low‐velocity (2 m/s) and at varying angles and sand concentrations (0.0, 0.05, 0.4 g/L). The results demonstrate good agreement between experimental data and model predictions across different erosive ...
