Multiplicity of periodic solutions in bistable equations [PDF]

open access: yes, 2004
We study the number of periodic solutions in two first order non-autonomous differential equations both of which have been used to describe, among other things, the mean magnetization of an Ising magnet in the time-varying external magnetic field.

Effects of Degree of Particle Melt and Crystallinity in SLS Nylon-12 Parts [PDF]

open access: yes, 2008
Differential Scanning Calorimetry (DSC) traces for SLS Nylon-12 parts display two distinct melt peaks, which have been related to the presence of both melted and crystallised regions, and un-melted particle cores within the part.

Observation of dressed excitonic states in a single quantum dot [PDF]

open access: yes, 2007
We report the observation of dressed states of a quantum dot. The optically excited exciton and biexciton states of the quantum dot are coupled by a strong laser field and the resulting spectral signatures are measured using differential transmission of ...
