An improved ADRC and its Application
Advances in Intelligent Systems Research, 2014 Electro-hydraulic servo control system has a typical large delay, nonlinear and time-varying characteristics, which is Controlled effectively by using ADRC. To optimize the parameters of ADRC quickly, the paper presents a new ADRC structure of configurable zero point, and analysis the effect of strong interference on the extended state observer, and ...

White Matter and Perivascular Imaging Changes in Alzheimer's Disease and Cerebral Amyloid Angiopathy
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Peak‐width of skeletonized mean diffusivity (PSMD) and diffusion tensor imaging–analysis along the perivascular space (DTI‐ALPS), reflecting white matter integrity and glymphatic function, are altered in Alzheimer's disease (AD).

Artificial Synaptic Device Based on Self‐Aligned c‐In2O3 TFTs With an Ultrathin MgO Interlayer
Advanced Materials Technologies, EarlyView.A coplanar synaptic thin‐film transistor based on crystalline In2O3 is demonstrated using a PECVD SiO2 gate insulator and an ultrathin MgO interlayer. The MgO interlayer suppresses excessive carrier density and may facilitate proton‐related interfacial polarization, resulting in stable counterclockwise hysteresis and synaptic behavior.

Advanced Materials Technologies, EarlyView.An O radical‐induced n‐to‐p transition in PbS quantum dots (QDs) is achieved via atmospheric Ar/O2 treatment, enabling favorable band alignment and stable photogating in PbS QD/IGZO phototransistors. Interfacial defect passivation and Fermi‐level modulation, confirmed by XPS and UPS analyses, effectively suppress dark current, induce a positive VTH ...

Research on Drum Water Level Control of Marine Auxiliary Boiler Based on ADRC
Polish Maritime Research, 2018 SThe active disturbance rejection control (ADRC) exhibits strong robustness and adaptability in the presence of strong interference of a large class of uncertain systems. In order to better control the water level of the auxiliary boiler drum, this paper

Perivascular Spaces as Determinants of Amyloid, Tau, and Vascular Biomarker Progression
Annals of Neurology, EarlyView.Objective Magnetic resonance imaging (MRI)‐visible enlarged perivascular spaces (PVS) are markers of cerebral small vessel disease (SVD) and aging, processes implicated in both neurodegenerative and cerebrovascular pathologies. However, longitudinal positron emission tomography (PET) studies examining PVS as a mechanism underlying Alzheimer's disease ...

Distribution of Big Tau Isoforms in the Human Central and Peripheral Nervous System
Annals of Neurology, EarlyView.Objective Tau is widely studied in neurodegeneration, yet most work has focused on canonical brain tau isoforms. A longer isoform, “big tau,” produced by inclusion of exon 4a, is expressed in the peripheral nervous system (PNS) and central nervous system (CNS) regions.

Tau hyperphosphorylation correlates with reduced methylation of protein phosphatase 2A
Neurobiology of Disease, 2008 The down-regulation of protein phosphatase 2A (PP2A) activity is thought to play an important role in the formation of tau hyperphosphorylation in the Alzheimer's disease (AD) brain. Methylation of the PP2A catalytic subunit at the L309 site can potently
