Abstract We uncover the interaction-induced \emph{stable self-localization} of few bosons in finite-size disorder-free superlattices. In these nonthermalized multi-particle states, one particles forms a superposition multiple standing waves, so that it provides quasi-random potential to localize other particles. derive effective Hamiltonians for self-localized states and find their energy level...

this study is aimed to identify sources of particulate matter with mean aerodynamic diameterbelow 10 μm (pm10) present in the atmosphere of the metropolitan area of mexico city (mamc), usingsamples obtained from january 1st to june 30th, 2009, analyzed with x-ray spectrometric techniques.minivol samplers were used to collect samples on polycarbonate filters in three sites (north, center, andsou...

we report a case of 48-year-old woman with multiple hydatid cysts in pararectal region and right paraovarian localization with an unusual sonographic and computed tomographic presentation mimicking a pelvic endometriosis. during laparotomy, multiple pararectal and right ovarian cysts resembling endometriosis were resected. pathologic examination gives the diagnosis of hydatid cysts. retrospecti...

Many real-world complex systems have small-world topology characterized by the high clustering of nodes and short path lengths.It is well-known that higher drives localization while shorter length supports delocalization eigenvectors networks. Using multifractals technique, we investigate properties adjacency matrices networks constructed using Watts-Strogatz algorithm. We find central part eig...

Recent results have shown that auditory localization in the horizontal plane is dramatically worse for listeners wearing double hearing protection ~earplugs and earmuffs! than it is for listeners wearing single hearing protection ~earplugs or earmuffs alone!. This suggests that double hearing protection might also impair the spatial unmasking that normally occurs when two simultaneous talkers a...
