Parametric tension between even and odd multipole data of WMAP power spectrum: unaccounted contamination or missing parameters?
Jaiseung Kim, Pavel Naselsky
There exist power contrast in even and odd multipoles of WMAP power spectrum at low and intermediate multipole range. This anomaly is explicitly associated with the angular power s…
CMB E/B decomposition of incomplete sky: a pixel space approach
Jaiseung Kim, Pavel Naselsky
CMB polarization signal may be decomposed into gradient-like (E) and curl-like (B) mode. We have investigated E/B decomposition in pixel space. We find E/B mixing due to incomplete…
Finite size melting of spherical solid-liquid aluminium interfaces
Johan Chang, Erik Johnson, Takamichi Sakai +1
We have investigated the melting of nano-sized cone shaped aluminium needles coated with amorphous carbon using transmission electron microscopy. The interface between solid and li…
Competition between Diffusion and Fragmentation: An Important Evolutionary Process of Nature
Jesper Ferkinghoff-Borg, Mogens H. Jensen, Joachim Mathiesen +2
We investigate systems of nature where the common physical processes diffusion and fragmentation compete. We derive a rate equation for the size distribution of fragments. The equa…
