Frequency of ZFHX3‐Mediated Spinocerebellar Ataxia 4 in a US Undiagnosed Ataxia Cohort

open access: yesMovement Disorders, EarlyView.
Abstract Background Spinocerebellar ataxia 4 (SCA4) is a late‐onset dominant ataxia with neuropathy caused by exonic GGC repeat expansion in the ZFHX3 gene thought to originate from a Swedish founder event. The GC‐rich expansion is highly thermodynamically stable, posing challenges for standard clinical genetic testing methods.

A Sub‐Microsecond Switch Enabling SWIFT 23Na Imaging at 10.5 T

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To enable sodium SWIFT imaging, which is a zero‐echo time imaging technique, at ultra‐high magnetic fields through the development of custom electronics hardware, and to showcase this capability with in vivo imaging results. Methods The custom hardware developed consists of a high‐speed optical trigger with 10 ns resolution, an in‐bore

Free‐Breathing Fat Quantification Using a Phase Error‐Corrected Cartesian Acquisition With Spiral Profile Ordering

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a phase‐corrected time‐interleaved multi‐echo gradient echo Cartesian acquisition with spiral profile ordering (TIMGRECASPR) for abdominal large‐FOV proton density fat fraction (PDFF) mapping at 3 T, demonstrating its sampling flexibility and inherent self‐gating capabilities at high isotropic resolutions.

The Stefan problem with convection [PDF]

open access: yes, 2012
The convection Stefan problem in liquid phase is investigated. We prove the theorem on the solvability. The approximate problem solution is constructed using the method of small parameter.

On a numerical approach to Stefan problem

open access: yes, 1993
A one-dimensional Stefan problem for a spherical particle moving in a plasma jet is solved by approximating the enthalpy formulation of the problem by $C^0$ piecewise linear finite elements in space combined with a semi-implicit scheme in ...

Adaptive Pudendal Nerve Stimulation: A Pilot Study on Safety, Technical Feasibility, and Clinical Effect

open access: yesNeurourology and Urodynamics, EarlyView.
ABSTRACT Purpose To evaluate the safety, procedural feasibility, and pilot clinical outcomes for a new implanted device delivering adaptive pudendal nerve stimulation. Materials and Methods Thirteen adult women with treatment‐refractory mixed (n = 8) or urge (n = 5) urinary incontinence were implanted with a Picostim‐DyNeuMo system incorporating an ...

Allocation of Indivisible Items With a Common Preference Graph: Minimizing Total Dissatisfaction

open access: yesNetworks, EarlyView.
ABSTRACT Allocating indivisible items among a set of agents is a frequently studied discrete optimization problem. In the setting considered in this work, the agents' preferences over the items are assumed to be identical. We consider a very recent measure for the overall quality of an allocation which does not rely on numerical valuations of the items.
