Localization of various sorts of optical excitations occur and recur in a wide gamut of disordered systems, such as inhomogeneous media, nanocomposite materials, layered structures, metal films and metal-dielectric composites.
One rhyme pair, "casuarinas" (referring to the cassowary tree) and "marinas," appeared originally in a haunting paean to the poet's ability to harmonize with nature in Walcott's 1997 book "The Bounty," and here recurs in a meditation on mortality that ends: "fear melts / before daylight's beauty, despite all that coughing".

Ongoing epidemiologic surveillance will be necessary to determine whether this pattern of HFMD and enterovirus activity recurs in a regular annual cycle.
Strain-focussed studies could also identify how many distinct HRVs circulate in a single respiratory season, how often a given strain recurs in a population and just how many HRV strains there are.
Bacterial, viral, fungal, or parasitic infections can be eradicated and recur at a time in the future requiring repetition of the same molecular assay for detection.

Unfortunately, however, distant metastases are present at the time of initial diagnosis in approximately one third of patients, and the tumor will recur in a further third, even after nephrectomy with curative intent [ 7, 8].
CONCLUSIONS: When properly diagnosed and treated, clinically apparent pulmonary embolism was an uncommon cause of death, and it recurred in only a small minority of patients.
