Data encryption using chaotic mechanical system vibration response signals [PDF]

open access: yes, 2021
The aim of the project is to establish the chaotic mechanical system by using an additional cubic spring stiffness and a fractional derivative term in a solid-spring damper system. When an external sinusoidal force is added to the system, the system will

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Ventilator-related causes of lung injury: the mechanical power

open access: yesIntensive Care Medicine, 2016
PurposeWe hypothesized that the ventilator-related causes of lung injury may be unified in a single variable: the mechanical power. We assessed whether the mechanical power measured by the pressure–volume loops can be computed from its components: tidal ...
