Childhood Material Hardship Linked to Adolescent Neurocognition: A Computational Modeling Approach. [PDF]

Dev Sci
ABSTRACT Childhood material hardship, including insecurity in housing, utilities, food, and medical care, is a critical factor influencing cognitive functioning and mental health outcomes. However, past research on material hardship is limited by cross‐sectional data and reliance on conventional behavioral measures of cognitive functioning that suffer ...

Assessing Measurement Repeatability of a Novel Anisotropic Phantom for Advanced Diffusion MRI Models. [PDF]

Magn Reson Med
ABSTRACT Purpose Diffusion MRI is widely used to characterize tissue microstructure, but standardization remains challenging, particularly for advanced models or regions with crossing fibers. Phantoms provide controlled environments to assess measurement repeatability independent of biological variability.

Using high angular resolution diffusion imaging data to discriminate cortical regions.

PLoS ONE, 2013
Brodmann's 100-year-old summary map has been widely used for cortical localization in neuroscience. There is a pressing need to update this map using non-invasive, high-resolution and reproducible data, in a way that captures individual variability.

In vivo high angular resolution diffusion-weighted imaging of mouse brain at 16.4 Tesla. [PDF]

PLoS ONE, 2015
Magnetic Resonance Imaging (MRI) of the rodent brain at ultra-high magnetic fields (> 9.4 Tesla) offers a higher signal-to-noise ratio that can be exploited to reduce image acquisition time or provide higher spatial resolution.

The role of management accounting system and organizational culture in mediating the relationship between mutual dependency and environmental uncertainty [PDF]

Accounting, 2022
This study aimed to develop a conceptual model of the mediating role of management accounting system (Broadscope) and organizational culture on the influence of mutual dependency and environmental uncertainty on managerial performance.

Martingale Morrey-Hardy and Campanato-Hardy Spaces [PDF]

Journal of Function Spaces and Applications, 2013
We introduce generalized Morrey-Campanato spaces of martingales, which generalize both martingale Lipschitz spaces introduced by Weisz (1990) and martingale Morrey-Campanato spaces introduced in 2012. We also introduce generalized Morrey-Hardy and Campanato-Hardy spaces of martingales and study Burkholder-type equivalence.

Parametric representation of multiple white matter fascicles from cube and sphere diffusion MRI. [PDF]

PLoS ONE, 2012
The characterization of the complex diffusion signal arising from the brain remains an open problem. Many representations focus on characterizing the global shape of the diffusion profile at each voxel and are limited to the assessment of connectivity ...

Scattered slice SHARD reconstruction for motion correction in multi-shell diffusion MRI

NeuroImage, 2021
Diffusion MRI offers a unique probe into neural microstructure and connectivity in the developing brain. However, analysis of neonatal brain imaging data is complicated by inevitable subject motion, leading to a series of scattered slices that need to be

Generalized Hardy’s Paradox [PDF]

Physical Review Letters, 2018
Here we present the most general framework for $n$-particle Hardy's paradoxes, which include Hardy's original one and Cereceda's extension as special cases. Remarkably, for any $n\ge 3$ we demonstrate that there always exist generalized paradoxes (with the success probability as high as $1/2^{n-1}$) that are stronger than the previous ones in showing ...
