Distinct Brain Drivers and Shared Cerebello–Cortical Input in ADCY5 and SGCE Hyperkinetic Movements

Movement Disorders, EarlyView.
Resting‐state fMRI and effective connectivity revealed distinct cerebellar–basal ganglia–cortical interactions in ADCY5 (MxMD‐ADCY5) and SGCE (MYC/DYT‐SGCE) related movement disorders. The cerebellum modulated cortex directly in MYC/DYT‐SGCE, but indirectly via basal ganglia‐cerebellar projections in MxMD‐ADCY5, which also showed reduced subthalamic ...

Quantitative Imaging of Pyruvate Metabolism in a Patient With Anaplastic Thyroid Cancer

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Magnetic resonance imaging using hyperpolarized (HP) [1‐13C]‐pyruvate enables assessment of pyruvate metabolism in vivo and offers new insight into metabolic changes in response to cancer therapy. Widely used semi‐quantitative metrics of pyruvate metabolism can be affected by physiological factors that are extrinsic to intracellular ...

A Smoothed P-Value Test When There is a Nuisance Parameter under the Alternative

, 2018
We present a new test when there is a nuisance parameter under the alternative hypothesis. The test exploits the p-value occupation time [PVOT], the measure of the subset of a nuisance parameter on which a p-value test rejects the null hypothesis.

VQ‐Wave: A Physics‐Driven Spatiotemporal Deep Learning Approach for Noncontrast‐Enhanced Lung Ventilation and Perfusion MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a robust deep learning framework for noncontrast‐enhanced functional lung MRI, overcoming the limitations of spectral decomposition in the presence of physiological nonstationarity. Methods We introduce VQ‐Wave (Ventilation/Q‐perfusion Waveform‐based Assessment of Variable Evolutions), a physics‐driven spatiotemporal ...

Micromotion-enabled improvement of quantum logic gates with trapped ions

New Journal of Physics, 2017
The micromotion of ion crystals confined in Paul traps is usually considered an inconvenient nuisance, and is thus typically minimized in high-precision experiments such as high-fidelity quantum gates for quantum information processing (QIP).

Ultrafast fMRI Detects Age‐Related Changes in Harmonics of Cardiac Pulsations in the Brain at 7 T

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Aging impacts pulsatility of blood vessels in the brain, reflecting vascular health. Resolving characteristics of cardiac pulsatility requires faster acquisitions than traditional fMRI. An ultrafast fMRI method was developed and applied to sample several harmonics of cardiac pulsations at 7 T.

More on confidence intervals for partially identified parameters [PDF]

This paper extends Imbens and Manski's (2004) analysis of confidence intervals for interval identified parameters. For their final result, Imbens and Manski implicitly assume superefficient estimation of a nuisance parameter.

Linking perceptions of weeds with approaches to weed management

People and Nature, EarlyView.
Abstract A multitude of factors can shape people's perceptions, leading to a variety of views on nature's services and values. The IPBES Values Framework highlights the ways that people and nature interact (both positively and negatively) through consideration of nature's contributions to people. For plants, differences in perceived values by different

Bayesian priors and nuisance parameters

, 2016
Bayesian techniques are widely used to obtain spectral functions from correlators. We suggest a technique to rid the results of nuisance parameters, ie, parameters which are needed for the regularization but cannot be determined from data. We give examples where the method works, including a pion mass extraction with two flavours of staggered quarks at
