Dynamic response of a two-story steel structure subjected to earthquake excitation by using deterministic and nondeterministic approaches

open access: yesJournal of the Mechanical Behavior of Materials, 2023
An earthquake is a random phenomenon in its intensity and frequency content. Since the earthquake is a signal that contains a band of frequencies, each frequency has a different energy. This means that the response of buildings to earthquakes depends not

Quantum Logic and the Histories Approach to Quantum Theory

open access: yes, 1993
An extended analysis is made of the Gell-Mann and Hartle axioms for a generalised `histories' approach to quantum theory. Emphasis is placed on finding equivalents of the lattice structure that is employed in standard quantum logic.

Parent‐to‐Child Information Disclosure in Pediatric Oncology

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Despite professional consensus regarding the importance of open communication with pediatric cancer patients about their disease, actual practice patterns of disclosure are understudied. Extant literature suggests a significant proportion of children are not told about their diagnosis/prognosis, which is purported to negatively ...

Predicting Chronicity in Children and Adolescents With Newly Diagnosed Immune Thrombocytopenia at the Timepoint of Diagnosis Using Machine Learning‐Based Approaches

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Objectives To identify predictors of chronic ITP (cITP) and to develop a model based on several machine learning (ML) methods to estimate the individual risk of chronicity at the timepoint of diagnosis. Methods We analyzed a longitudinal cohort of 944 children enrolled in the Intercontinental Cooperative immune thrombocytopenia (ITP) Study ...

Response modification factor of eccentrically braced frames with reduced beam section [PDF]

open access: yesJournal of Structural and Construction Engineering, 2018
Eccentrically braced frames are one of the most proper lateral resisting systems in seismic areas. The link beam in an eccentrically braced frame acts like a structural fuse, which is able to sustain large plastic shear or flexural deformations ...

Studies on the Seismic Design of Low-Rise Steel Buildings [PDF]

open access: yes, 1977
The behavior of low-rise steel shear buildings, moment frame buildings, and X-braced buildings, subjected to earthquake base motion, is studied using inelastic time-history analysis.
