Closed-form critical earthquake response of elastic-plastic structures on compliant ground under near-fault ground motions

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 ...

Saturated impulse and application of saturation equivalent method in cabin explosion

Zhongguo Jianchuan Yanjiu, 2021
ObjectivesFor the ship structures subjected to pulse loading such as explosion or slamming, research on the "saturated impulse" phenomenon shows that designing hull structures with maximum loading amplitude and total impulse is unreasonable.

Time variation in the dynamics of worker flows:evidence from North America and Europe [PDF]

, 2014
Vector autoregressive methods have been used to model the interrelationships between job vacancy rates, job separation rates and job-finding rates using tools such as impulse response analysis.

Critical Steady-State Response of Single-Degree-of-Freedom Bilinear Hysteretic System under Multi Impulse as Substitute of Long-Duration Ground Motion

Frontiers in Built Environment, 2017
A set of multiple impulses is introduced as a substitute of many-cycle harmonic waves which represent the long-duration earthquake ground motion. A closed-form expression is derived of the elastic–plastic response of a single-degree-of-freedom structure ...

A PRSZT Registry Analysis of Prognostic Factors Influencing Survival and Relapse Rates After Second Allogeneic Hematopoietic Stem Cell Transplantation in Pediatric Acute Lymphoblastic Leukemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT A second allogeneic (allo‐)hematopoietic stem cell transplantation (HSCT2) is a potential curative option for pediatric patients with acute lymphoblastic leukemia (ALL) following relapse after first allogeneic transplantation (HSCT1), but its efficacy is limited by high relapse rates and transplant‐related toxicity in highly pretreated ...

Critical response of a single-degree-of-freedom system with bilinear hysteresis and viscous damping under triple impulse

Frontiers in Built Environment
A triple impulse is used as a mathematical model of forward-directivity inputs, which are fault-normal components of near-fault earthquake ground motions. In this paper, two types of the triple impulse input are employed.

Critical earthquake response of a SDOF elastic‐perfectly plastic model with viscous damping under double impulse as a substitute for near‐fault ground motion

Japan Architectural Review, 2018
The double‐impulse input is introduced as a substitute for the fling‐step near‐fault ground motion, and a closed‐form solution for the approximate elastic‐plastic response of a structure with viscous damping under the “critical double impulse” is derived.

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Wide-band modelling of tower-footing grounding systems based on the impulse response measurement [PDF]

Zbornik Radova: Elektrotehnički Institut "Nikola Tesla", 2019
The tower footing grounding system is of major importance for analysis of the lightning overvoltages on an overhead transmission line during backflashover and shielding failure.

The problem of offset in acoustic pulse reflectometry [PDF]

, 2007
Acoustic pulse reflectometry has become established as a useful non-invasive technique for measuring a variety of duct properties. A sound pulse is injected into the duct under investigation and the resultant reflections are recorded.
