Left Main Stem Perforation: Management Strategies in a Potentially Catastrophic Event

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Left main stem coronary perforation is a potentially fatal complication of percutaneous coronary intervention if not recognized early and treated emergently. Treating left main stem perforation can be challenging due to the significant hemodynamic effect of one of the important steps, namely balloon tamponade.

Solving constraints within a graph based dependency model by digitising a new process of incrementally casting concrete structures [PDF]

open access: yes, 2008
The mechanisation of incrementally casting concrete structures can reduce the economic and environmental cost of the formwork which produces them. Low-tech versions of these forms have been designed to produce structures with cross-sectional continuity ...

Transitioning Formamide Solvothermal Syntheses of MOFs to Less Toxic Solvents

open access: yesChemistry – A European Journal, EarlyView.
Metal‐organic Frameworks (MOFs) are commonly synthesized in toxic formamide solvents. This study investigates the synthetic factors required for effective removal of formamides across various classes of MOFs, providing a foundation for designing new sustainable MOF syntheses.

The linear instability of the stratified plane Couette flow

open access: yes, 2017
We present the stability analysis of a plane Couette flow which is stably stratified in the vertical direction orthogonally to the horizontal shear. Interest in such a flow comes from geophysical and astrophysical applications where background shear and ...

Modern semiclassical theory of magnetic transport and breakdown

open access: yes, 2018
The Bohr-Sommerfeld quantization rule lies at the heart of the modern semiclassical theory of a Bloch electron in a magnetic field. This rule is predictive of Landau levels and quantum oscillations for conventional metals, as well as for a host of ...
