On its surface, E. Hedinger AG v. Brainwave Science looks like a standard lawsuit alleging breach of contract. But the plaintiff’s claims go much further. Electromechanical company Hedinger (Wattwil, Switzerland) sued “brain-fingerprinting” company Brainwave Science (Southborough, Mass.) in 2017 in Massachusetts Superior Court over a distribution agreement that Hedinger claims Brainwave breached about a year after it was signed in 2016. This week, a federal judge in Delaware ordered Brainwave and Hedinger to arbitration over Hedinger’s claims of breach-of-contract, fraud, and of selling counterfeit ...

Publication date: June 2019Source: Materials Science and Engineering: C, Volume 99Author(s): Pawan Sharma, Pulak M. PandeyAbstractThe presented work aims to evaluate the effect of porosity on the corrosion behaviour of porous iron scaffold for biodegradable implant application. Two different types of iron scaffold samples were prepared using a newly developed process based on the amalgamation of 3D printing and pressureless microwave sintering. Random porous iron scaffold (RPIS) sample having only random microporous structure and topologically ordered porous iron scaffold (TOPIS) sample having designed interconnected macro...

Publication date: 11 March 2019Source: Materials Science and Engineering: A, Volume 749Author(s): Ahad Shafiee, Jongun Moon, Hyoung Seop Kim, Mohammad Jahazi, Mahmoud Nili-AhmadabadiAbstractA newly developed precipitation-hardened high entropy superalloy was produced using double vacuum melting, and its microstructural evolutions were examined after homogenization, hot rolling, annealing, and aging. The precipitation behaviour of the samples was studied using two different heat treatment cycles (with and without solution treatment). Microstructural observations using scanning electron microscope and transmission electron m...

Scanning electron microscopy images of the HFM indicated that a neat hollow structure was obtained through a single shot spinneret. Moreover, the finger-like and sponge-like structure of the HFM had a hierarchical struc...

Publication date: Available online 5 February 2019Source: NeuroImageAuthor(s): Jingyuan E. Chen, Jonathan R. Polimeni, Saskia Bollmann, Gary H. GloverAbstractRecent advances in parallel imaging and simultaneous multi-slice techniques have permitted whole-brain fMRI acquisitions at sub-second sampling intervals, without significantly sacrificing the spatial coverage and resolution. Apart from probing brain function at finer temporal scales, faster sampling rates may potentially lead to enhanced functional sensitivity, owing possibly to both cleaner neural representations (due to less aliased physiological noise) and additio...

This study investigated the properties and mechanisms of PA variability across heartbeats, which has remained largely unaddressed to date, and evaluated its impact on PA correction approaches. Simultaneous EEG-fMRI was performed at 7T on healthy participants at rest or under visual stimulation, with concurrent recordings of breathing and cardiac activity. PA variability was found to contribute to EEG variance with more than 500 μV2 at 7T, which extrapolates to 92 μV2 at 3T. Clustering analyses revealed that PA variability not only is linked to variations in head position/orientation, as previously hypothesized, but a...

ConclusionsPBSR-MRSI combines the benefits of ultra-high-field MR systems, cutting-edge MRSI, and advanced postprocessing to allow millimetric resolution molecular imaging of glioma tissue beyond standard methods. An ideal example is the accurate imaging of glutamine, which is a prime target of modern therapeutic approaches, made possible due to the higher spectral resolution of 7 T systems.Graphical abstract
