The origin of IRS 16: dynamically driven inspiral of a dense star cluster to the Galactic center? [PDF]

open access: yes, 2003
We use direct N-body simulations to study the inspiral and internal evolution of dense star clusters near the Galactic center. These clusters sink toward the center due to dynamical friction with the stellar background, and may go into core collapse ...

A Modified Catenary Model with Application to the Analysis and Design of Retrofit Cables for Progressive Collapse

open access: yesInfrastructures, 2018
Progressive collapse, the extensive or complete collapse of a structure resulting from the failure of one or a small number of structural components, has become a focus of research efforts and design considerations following events occurring at the Ronan

Performance Assessment of an Energy–Based Approximation Method for the Dynamic Capacity of RC Frames Subjected to Sudden Column Removal Scenarios

open access: yesApplied Sciences, 2021
The alternative load path method is widely used to assess the progressive collapse performance of reinforced concrete structures. As an alternative to an accurate non–linear dynamic analysis, an energy–based method (EBM) can also be adopted to ...

A review of progressive collapse research and regulations [PDF]

open access: yes, 2014
History has demonstrated that buildings designed to conventional design codes can lack the robustness necessary to withstand localised damage, partial or even complete collapse. This variable performance has led governmental organisations to seek ways of

Experimental Investigation of Progressive Collapse of Prestressed Concrete Frames after the Loss of Middle Column

open access: yesAdvances in Civil Engineering, 2020
Accidental loads such as explosion and vehicle impact could lead to failure of one or several load-bearing members in the structures, which is likely to trigger disproportionate progressive collapse of overall structures.

Disproportionate collapse analysis of mid-rise cross-laminated timber buildings [PDF]

open access: yes, 2018
This paper investigates the structural behaviour of a twelve-storey Cross-Laminated Timber (CLT) building subjected to sudden removal of internal and external ground floor loadbearing walls, and computes the probability of disproportionate collapse ...

Are Low Testosterone and Sex Differences in Immune Responses Causing Mass Hysteria during the Coronavirus Pandemic?

open access: yesScience & Philosophy, 2020
By integrating the entire body of research in human sexual dynamics, immune responses, and sociocultural behavior, we can conclude that the mass hysteria our society is currently experiencing originates in our evolved psychological adaptations to ...

Nonlinear analysis on progressive collapse of tall steel composite buildings

open access: yesCase Studies in Construction Materials, 2018
Progressive collapse is defined as the expansion of an initial local failure of an element into another element of the structure and ultimately leading to the collapse of the whole structure or a large part of it in a disproportionate way.

Progressive collapse risk analysis: literature survey, relevant construction standards and guidelines [PDF]

open access: yes, 2012
A technical literature survey has been conducted concerning the problems of building robustness and progressive collapse. These issues gained special interest in construction after the partial collapse of the Ronan Point apartment building in London in ...

Ventricular response during lungeing exercise in horses with lone atrial fibrillation [PDF]

open access: yes, 2013
Reasons for performing the study Atrial fibrillation (AF) is the most important dysrhythmia affecting performance in horses and has been associated with incoordination, collapse and sudden death.
