Precision machine learning to understand micro-RNA regulation in neurodegenerative diseases

open access: yesFrontiers in Molecular Neuroscience, 2022
Micro-RNAs (miRNAs) are short (∼21 nt) non-coding RNAs that regulate gene expression through the degradation or translational repression of mRNAs.

Posterior Cortical Cognitive Deficits Are Associated With Structural Brain Alterations in Mild Cognitive Impairment in Parkinson’s Disease

open access: yesFrontiers in Aging Neuroscience, 2021
Context: Cognitive impairments are common in patients with Parkinson’s disease (PD) and are heterogeneous in their presentation. The “dual syndrome hypothesis” suggests the existence of two distinct subtypes of mild cognitive impairment (MCI) in PD: a ...

Email Shape Analysis [PDF]

open access: yes, 2010
Email has become an integral part of everyday life. Without a second thought we receive bills, bank statements, and sales promotions all to our inbox. Each email has hidden features that can be extracted. In this paper, we present a new mechanism to characterize an email without using content or context called Email Shape Analysis.

Effects of hypertension on subcortical nucleus morphological alternations in patients with type 2 diabetes

open access: yesFrontiers in Endocrinology, 2023
ObjectivesType 2 diabetes mellitus(T2DM) and hypertension(HTN) are common comorbidities, and known to affect the brain. However, little is known about the effects of the coexisting HTN on brain in T2DM patients. So we aim to investigate the impact of HTN

Aging due to successive reuse of polyamide 12 powder during laser sintering: extrinsic powder properties and quality of sintered parts [PDF]

open access: yesMATEC Web of Conferences, 2022
The effects of cumulative build time during the reuse of polyamide 12 (PA 12) for laser sintering (LS) on the morphology, size and shape distribution of the feedstock powder and quality of printed parts were investigated in this study.

Secondary Folds Contribute Significantly to the Total Surface Area in the Olfactory Organ of Chondrichthyes

open access: yesFrontiers in Physiology, 2019
The olfactory organ of Chondrichthyes is characterized by a central support with several lamellae covered by a sensory olfactory epithelium. Although secondary folds are present on the lamellae in all the chondrichthyan species analyzed to date, their ...

STEREOLOGICAL ANALYSIS OF SHAPE

open access: yesImage Analysis & Stereology, 2011
This paper concerns the problem of making stereological inference about the shape variability in a population of spatial particles. Under rotational invariance the shape variability can be estimated from central planar sections through the particles. A simple, but flexible, parametric model for rotation invariant spatial particles is suggested.

保形分段三次多项式曲线的形状分析(Construction and analysis of a new class of shape-preserving piecewise cubic polynomial curves)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2018
This paper proposes a new class of shape-preserving piecewise cubic polynomial curves with both local and global shape control parameters. By presetting the properties of its basis functions and then solving equations,a set of polynomial basis functions ...
