Quantifying Soft‐Surgery in Cochlear Implantation: Multimodal Data From 30 International Specialists
The Laryngoscope, EarlyView.Objective data from 30 specialist cochlear implant surgeons showed that surgical handling strongly influences intracochlear mechanical stress during implantation. Surgeons with fewer than 50 lifetime insertions performed significantly worse than more experienced colleagues, while self‐assessment did not reflect objective performance in any group ...

Metasurface‐Based Polarization‐Controlled Generation of 128‐Dimensional Vector Vortex Combs
Laser &Photonics Reviews, EarlyView.The generation and continuous control of 128‐dimensional vector vortex combs using a single metasurface is reported. This work creates a class of structured light that uniquely integrates ultrahigh dimensionality with vector properties, and represents a crucial step toward on‐chip, reconfigurable generators for ultrahigh‐dimensional vector structured ...

Some statistical properties of spiral galaxies
, 1999 This paper presents some statistical correlations of 72 northern spiral galaxies. The results show that early-type spirals that are brighter, and thicker, and the axis ratios (H-z/H-r) of the disk tend to be smaller along the Hubble sequence.

Mass Spectrometry Reviews, EarlyView.ABSTRACT Top‐down proteomics (TDP) characterizes proteoforms in cells, tissues, and biofluids, in discovery mode and on a global scale, requiring analytical tools with high peak capacity for proteoform separation and high sensitivity for proteoform detection, given the extremely high proteoform complexity and wide proteoform concentration dynamic range.

mLife, EarlyView.Abstract Biological nitrogen fixation in symbiotic diazotrophs is subject to oxygen regulation by an oxygen‐sensing FixLJ two‐component system under micro‐oxic conditions. However, it remains unclear whether this mechanism is conserved in free‐living diazotrophs.

Field‐Cycling NMR Relaxometry in Tire Elastomer Science
Magnetic Resonance in Chemistry, EarlyView.Field‐cycling NMR relaxometry has established as an ideal tool to investigate multiscale polymer dynamics. Here, we review and discuss applications on elastomers and elastomer compounds of interest for the tire industry to obtain information on segmental dynamics and on polymer dynamics over different regimes as a function of chain length in polymer ...

Fully‐Constrained Variable Projection for Water‐Fat Models
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose Variable projection (VARPRO) is an effective technique to reduce the dimensionality of least squares optimization problems through the elimination of linear parameters. For water‐fat models, constrained VARPRO variants have been proposed in the literature to ensure that water and fat components are aligned at TE = 0, thereby preventing

Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose To enable flexible dynamic and DCE MRI with low acoustic noise and high spatiotemporal resolution using zero echo time (ZTE) imaging. Methods This work proposes Arc‐ZTE, a technique in which the readout gradients of ZTE are continuously‐slewed to form arcs in k‐space that are sequentially rotated to yield an incoherent trajectory ...

Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose To integrate MR‐based servo navigation in MPRAGE and 3D‐TSE sequences and demonstrate its potential for prospective head motion correction in structural imaging. Methods Repeated modules of servo navigators were inserted before each preparation pulse of MPRAGE and 3D‐TSE sequences (before‐prep) for rapid convergence of motion parameter
