A Fully Automated Approach to Spike Sorting
View on Elsevier
Rapid magnetic resonance measurement of global cerebral metabolic rate of oxygen consumption in humans during rest and hypercapnia
TLDR
This study sought to further investigate the vascular and metabolic effects of hypercapnia by simultaneously measuring global venous oxygen saturation (SvO2) and total cerebral blood flow (tCBF) and suggesting a correlation between cerebral vascular reactivity (CVR) and baseline tCBF.

SpikeInterface, a unified framework for spike sorting
TLDR
SpikeInterface, a Python framework designed to unify preexisting spike sorting technologies into a single codebase and to standardize extracellular data file operations, is provided and it is demonstrated how it can improve the accessibility, reliability, and reproducibility of spike sorting in preparation for the widespread use of large-scale electrophysiology.

The shear modulus of the nucleus pulposus measured using magnetic resonance elastography: A potential biomarker for intervertebral disc degeneration
TLDR
The shear modulus of nucleus pulposus is measured in intact human vertebra–disc–vertebra segments using a magnetic resonance elastography setup for a 7T whole‐body scanner to quantify the effect of disc degeneration and compare the NP shearmodulus to other magnetic resonance‐based biomarkers of dis degeneration.

A parallel non-uniform fast Fourier transform library based on an "exponential of semicircle" kernel
TLDR
FINUFFT is presented, an efficient parallel library for type 1 (nonuiform to uniform), type 2 (uniform to nonuniform), or type 3 (non uniform toNonuniform) transforms, in dimensions 1, 2, or 3, which uses minimal RAM, requires no precomputation or plan steps, and has a simple interface to several languages.

SpikeForest: reproducible web-facing ground-truth validation of automated neural spike sorters
TLDR
SpikeForest is an open-source and reproducible software suite that benchmarks the performance of automated spike sorting algorithms across an extensive, curated database of electrophysiological recordings with ground truth, displaying results interactively on a continuously-updating website.

Implications of noise and resolution on mechanical properties of trabecular bone estimated by image‐based finite‐element analysis
TLDR
Systematic errors manifesting in significant deviations of the slopes from unity are caused by higher apparent bone‐volume fraction of the MR images but can potentially be corrected with appropriate histogram‐standardization techniques.

Retrospective correction for induced magnetic field inhomogeneity in measurements of large‐vessel hemoglobin oxygen saturation by MR susceptometry
TLDR
Compared to shimming the retrospective correction technique improved agreement between hemoglobin saturations measured in different segments of a vessel (femoral versus popliteal artery and vein) from three standard errors to less than one.
