An Optimized Pulse-Counting Method for Compensation Vector Calculation in the Automatic Balancer

open access: yesShock and Vibration, 2020
The accuracy of the counterweight positions in an automatic balancing system deeply affects dynamic balancing. Compensation vector is synthesized by the two counterweights located in the electromagnetic dual-weight automatic balancer.

Iterative filtering for semi-fragile self-recovery [PDF]

open access: yes2014 IEEE International Workshop on Information Forensics and Security (WIFS), 2014
In this paper we propose a novel scheme for semifragile self-recovery based on iterative filtering of randomly sampled image sections. The scheme exhibits very good robustness against both malicious tampering and lossy JPEG compression with only slight deterioration of the reconstruction quality with attack strength.

Long‐Term Follow‐Up of Chemotherapy‐Associated Biological Aging in Women With Early Breast Cancer

open access: yesAging and Cancer, EarlyView.
Women threated with adjuvant chemotherapy for early breast cancer have sustained long‐term increase in p16INK4a,, a robust marker of cell senescence, suggesting a chemotherapy‐associated age acceleration. p16INK4a as well as other biomarkers may identify patients at greatest risk for senescence‐related diseases of aging.

Innate Immune Reprogramming Mediated by Endogenous Retroelement Dysregulation Drives Multiple Sclerosis Progression

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
Epigenetic reprogramming in hematopoietic stem and progenitor cells (HSPCs) and downstream myeloid cells, mediated by H3.3 downregulation and endogenous retroelement (ERE) overexpression, contributes to the progression of multiple sclerosis (MS). ABSTRACT Background Skewed myelopoiesis in the bone marrow has been identified as a key driver of multiple ...
