Frontiers in Built Environment, 2015 The double impulse input is introduced as a substitute of the fling-step near-fault ground motion and a closed-form solution of the elastic-plastic response of a structure by the ‘critical double impulse input’ is derived.

Frontiers in Built Environment, 2021 An explicit limit for the overturning of a rigid block is derived on the input level of the triple impulse and the pseudo-triple impulse as a modified version of the triple impulse that are a substitute of a near-fault forward-directivity ground motion ...

Frontiers in Built Environment, 2020 This paper is aimed at proposing a hysteretic-viscous hybrid (HVH) damper system for tall buildings subjected to long-period pulse-type earthquake ground motions of extremely large amplitudes. The HVH system was introduced for a single-degree-of-freedom (

Frontiers in Built Environment, 2016 The double impulse is introduced as a substitute of the fling-step near-fault ground motion. A closed-form solution of the elastic-plastic response of a structure on compliant (flexible) ground by the ‘critical double impulse’ is derived for the first ...

Robustness analysis of elastoplastic structure subjected to double impulse [PDF]
Journal of Sound and Vibration, 2016 Abstract The double impulse has extensively been used to evaluate the critical response of an elastoplastic structure against a pulse-type input, including near-fault earthquake ground motions. In this paper, we propose a robustness assessment method for elastoplastic single-degree-of-freedom structures subjected to the double impulse input ...

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Optimal Viscous Damper Placement for Elastic-Plastic MDOF Structures Under Critical Double Impulse
Frontiers in Built Environment, 2019 A new method for optimal viscous damper placement is proposed for elastic-plastic multi-degree-of-freedom (MDOF) structures subjected to the critical double impulse as a representative of near-fault ground motions.

Examining Metal Additives in a Marine Hybrid-Propellant, Water-Breathing Ramjet
Journal of Marine Science and Engineering, 2022 This research focuses on theoretically and experimentally evaluating the performance of a metallized hybrid-propellant, water-breathing ramjet. The aluminum and/or magnesium particles added to a polymeric (polyester) fuel grain are hydro-reactive, using ...
