Fermionic and Bosonic Stabilizing Effects for Type I and Type II Dimension Bubbles

, 2004
We consider two types of "dimension bubbles", which are viewed as 4d nontopological solitons that emerge from a 5d theory with a compact extra dimension. The size of the extra dimension varies rapidly within the domain wall of the soliton.

String Figuring young children's perspectives of quality in English early childhood education and care

British Educational Research Journal, EarlyView.
Abstract Quality in early childhood education and care (ECEC) is a contested concept and has generally been conceptualised by inter‐related indicators such as staff qualifications, educational environment, policy or child‐to‐staff ratios. There has been a more limited emphasis on how young children might perceive and experience quality.

Stokes tomography of radio pulsar magnetospheres. II. Millisecond pulsars

, 2011
The radio polarization characteristics of millisecond pulsars (MSPs) differ significantly from those of non-recycled pulsars. In particular, the position angle (PA) swings of many MSPs deviate from the S-shape predicted by the rotating vector model, even
