Electroencephalographic Normalization as a Biomarker of Clinical Recovery in Down Syndrome Regression Disorder

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Down syndrome regression disorder is a syndrome characterized by subacute loss of cognitive, behavioral, and functional abilities in individuals with Down syndrome. Electroencephalography abnormalities are frequently observed during evaluation, but it remains unclear whether these findings represent a dynamic marker of disease ...

Comparison and application of small strain shear moduli from field and laboratory measurements

open access: yesYantu gongcheng xuebao, 2019
The small-strain shear modulus plays an important role in the calculations of ground seismic response and deformation in deep excavations. The values of the small strain shear modulus G0 of Shanghai soils by field and laboratory tests are investigated ...

Laboratory Investigation of the Mechanical Properties of a Rubber–Calcareous Sand Mixture: The Effect of Rubber Content

open access: yesApplied Sciences, 2020
This paper introduces a rubber–calcareous sand mixture as a lightweight building material in offshore engineering. The mechanical properties of mixtures of varying rubber contents were investigated by performing a one-dimensional (1-D) compression test ...

The influence of suction changes on the stiffness of railway formation

open access: yes, 2011
Despite compacted soils being unsaturated, geotechnical design is predominantly based on saturated soils,despite it being known that differences exist between the behaviour of saturated and unsaturated soils.Suction in soils has been shown to increase ...

Effects of loess content on dynamic shear modulus and damping ratio of Taiyuan sand

open access: yesYantu gongcheng xuebao, 2019
The mixtures of loess and Taiyuan sand are distributed widely along the No. 2 metro line of Taiyuan, which leads to an urgent need for the dynamic shear modulus G and damping ratio λ to analyze the seismic response.

Natural Frequencies of Levodopa‐Induced Dyskinesia in Parkinson's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Abnormal involuntary movements, known as dyskinesias, are common complications of levodopa treatment in patients with Parkinson's disease and can significantly impair quality of life. The underlying pathophysiology remains unclear, and current therapeutic options are limited.
