An Euclidean bounce describing vacuum decay can be considered as an infinite stack of concentric thin shells to which a thin-wall action can be assigned. The integral over all shells produces then a tunneling action that is precisely the action functional in field space of the so-called tunneling potential formalism.

Tuning wall thickness of TiO2 microtubes for an enhanced photocatalytic activity with thickness-dependent charge separation efficiency [PDF]
TiO microtubes with tunable wall thickness have been synthesized by a one-step electrospinning method linked with a calcination process. The wall thickness of TiO microtubes can be easily tuned by altering the dosage of liquid paraffin.

Increased ocular wall thickness and decreased globe volume in children with mucopolysaccharidosis type VI [PDF]
PURPOSE: Although clinical ophthalmologic findings have been reported, no study documented magnetic resonance imaging (MRI) findings in mucopolysaccharidosis (MPS) type VI. The aim of this study was to determine the ophthalmologic imaging findings of MPS

Regional Heterogeneity of LV Wall Thickness
Segmental variation in left ventricular (LV) wall thickness is important in characterizing hypertrophic cardiomyopathy, post-infarction remodeling, and myocardial noncompaction. In each of these disorders, cardiac magnetic resonance (CMR) has greatly extended our understanding due to its ability ...

Effect of element wall thickness on the homogeneity and isotropy of hardness in SLM IN718 using nanoindentation [PDF]
In this paper the homogeneity and isotropy of the mechanical hardness of thin-walled Inconel 718 (IN718) alloy samples manufactured by Selective Laser Melting (SLM) were examined using nanoindentation testing.
