On the origin of the narrow peak and the isospin symmetry breaking of the X(3872)
"... The X (3872) formation and decay processes in B-decay are investigated by a cc̄–two-meson hybrid model. The two-meson state consists of the D0 D∗0, D+D∗−, J/ψρ, and J/ψω channels. The energy-dependent decay widths of the ρ and ω mesons are introduced. The D–D ∗ inter-action is taken to be consistent ..."

to be consistent with a lack of the B B ∗ bound state. The coupling between the DD ∗ and J/ψρ or the DD ∗ and J/ψω channels is obtained from a quark model. The cc–DD∗ coupling is taken as a parameter to fit the X (3872) mass. The spectrum is calculated up to 4 GeV. It is found that very narrow J/ψρ and J/ψω peaks
Articulated body motion capture by annealed particle filtering
- In IEEE Conf. on Computer Vision and Pattern Recognition
, 2000
"... The main challenge in articulated body motion tracking is the large number of degrees of freedom (around 30) to be recovered. Search algorithms, either deterministic or stochastic, that search such a space without constraint, fall foul of exponential computational complexity. One approach is to intr ..."

special preparation of subjects or restrictive assumptions. The principal contribution of this paper is the development of a modified particle filter for search in high dimensional configuration spaces. It uses a continuation principle, based on annealing, to introduce the influence of narrow peaks

Power laws, Pareto distributions and Zipf’s law
"... Many of the things that scientists measure have a typical size or “scale”—a typical value around which individual measurements are centred. A simple example would be the heights of human beings. Most adult human beings are about 180cm tall. There is some variation around this figure, notably dependi ..."

the distribution is relatively narrow and peaked around 180cm. Another telling observation is the ratio of the heights of the tallest and shortest people.
Observation of Bose-Einstein condensation in a dilute atomic vapor
- Science
, 1995
"... A Bose-Einstein condensate was produced in a vapor of rubidium-87 atoms that was confined by magnetic fields and evaporatively cooled. The condensate fraction first appeared near a temperature of 170 nanokelvin and a number density of 2.5 x 1012 per cubic centimeter and could be preserved for more t ..."

than 15 seconds. Three primary signatures of Bose-Einstein condensation were seen. (i) On top of a broad thermal velocity distribution, a narrow peak appeared that was centered at zero velocity. (ii) The fraction of the atoms that were in this low-velocity peak increased abruptly as the sample
