Obstructive sleep apnoea is associated with dynamic intra-thoracic central airway collapse: results of a 10-year multi-centre retrospective analysis

Sleep Science and Practice, 2020
Background Disproportionate bulging of the pars membranosa into the central airway on expiration, now termed ‘excessive dynamic airway collapse’ (EDAC), has poorly characterised significance.

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

Infrastructures, 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

Applied 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 ...

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

Advances 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.

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

Science & 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

Case 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.

Food insecurity, state fragility and youth mental health: A global perspective

SSM: Population Health, 2021
Youth in fragile settings face disproportionate risks of experiencing food insecurity and poor mental health. Cross-national evidence is lacking on the association between food insecurity and mental health in youth populations, and on state fragility as ...

Disproportionate collapse of a cable-stayed bridge

Proceedings of the Institution of Civil Engineers - Bridge Engineering, 2019
The disproportionate collapse of an existing cable-stayed bridge was investigated at the numerical level by employing a validated model from the literature and the applied-element method. An earthquake input was used for the numerical simulations and applied at increasing intensity to assess the bridge response.
