Tau hyperphosphorylation correlates with reduced methylation of protein phosphatase 2A

open access: yesNeurobiology 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

Robust ADRC Control – Tuning and Discrete Implementation

open access: yesPomiary Automatyka Robotyka, 2022
This paper presents the robust Active Disturbance Rejection Control method in an aerodynamical object with two degrees of freedom. Full derivation of control algorithm equations and the settings values depending on the desired properties of the system, based on the dynamics of the second order oscillating object, have been shown.

Coding artifacts robust resolution up-conversion [PDF]

open access: yes, 2007
In this paper, an integrated resolution up-conversion and compression artifacts removal algorithm is proposed. Local image patterns are classified into object details or coding artifacts using the combination of structure information and activity measure.

AI‐enabled bumpless transfer control strategy for legged robot with hybrid energy storage system

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
Abstract Designing Hybrid energy storage system (HESS) for a legged robot is significant to improve the motion performance and energy efficiency of the robot. However, switching between the driving mode and regenerative braking mode in the HESS may generate a torque bump, which has brought significant challenges to the stability of the robot locomotion.

Therapeutic angiogenesis for patients with no-option critical limb ischemia by adipose-derived regenerative cells: TACT-ADRC multicenter trial

open access: yesAngiogenesis, 2022
Patients with critical limb ischemia (CLI) still have a high rate of lower limb amputation, which is associated with not only a decrease in quality of life but also poor life prognosis.

Embracing Sensitivity, Enhancing Impact: Developing A Co-Production Model of Public Engagement for Administrative Data Research

open access: yesInternational Journal of Population Data Science, 2020
Introduction Public engagement and impact are important to research funders. But how these are done successfully in administrative data research is less established than in research where engagement mechanisms are more embedded. As admin data research is
