Global existence for a translating near-circular Hele-Shaw bubble with surface tension [PDF]
, 2009 This paper concerns global existence for arbitrary nonzero surface tension of bubbles in a Hele-Shaw cell that translate in the presence of a pressure gradient.

Particle production by the expanding thin-walled bubble
, 2003 Neglecting the effect of particle production at the moment of bubble nucleation, the spectrum of created particles during the bubble expansion is evaluated in the thin-wall approximation.

The myths of the South Sea Bubble [PDF]
, 2002 The South Sea Bubble of 1720 looms large in popular depictions of eighteenth-century Britain. But in many respects it is seriously misunderstood. This article begins by exploring mythic ‘facts’ about the events of 1720, but is also concerned to explore ...

Advanced Engineering Materials, EarlyView.In‐mold electronics (IME) undergo complex thermoforming and over‐molding processes that strain device integrity. This study demonstrates how adapting the amount and placement of structural adhesive to local deformation levels preserves electrical functionality.

CFD-DEM Investigation on van der Waals Force in Gas-Solid Bubbling Fluidized Beds [PDF]
Journal of Chemical and Petroleum Engineering, 2018 Effect of interparticle force on the hydrodynamics of gas-solid fluidized beds was investigated using the combined method of computational fluid dynamics and discrete element method (CFD-DEM). The cohesive force between particles was considered to follow

Surface Modification of Fluorine‐Free Superhydrophobic Materials with (Ultra‐)Thin TiO2 Layers
Advanced Engineering Materials, EarlyView.Significant changes in wettability, with a reduction of 60o in the water conduct angle, are reported via the surface modification of fluorine‐free superhydrophobic thin films, prepared by aerosol‐assisted chemical vapor deposition, after coating a 4 nm layer of titanium dioxide on the surface using atomic layer deposition.

Advanced Engineering Materials, EarlyView.A near infrared‐responsive microscale cantilever is developed using a 3D‐printable composite based on photocurable resin consisting of sepiolite and graphene flakes. The material absorbs 1064 nm light, causing shape transformation with an average displacement of 1.3 mm in 1.7 s. Displacement is measured via video recording.

Journal of High Energy Physics, 2012 We propose an alternative mechanism of baryogenesis in which a scalar baryon undergoes a percolating first-order phase transition in the early Universe. The potential barrier that divides the phases contains explicit B and CP violation and the corresponding instanton that mediates decay is therefore asymmetric.
