In this pa.er we a.a.yze a.long sta.ding problem of the a.pea.a.ce of spurious,non-physica. solutions a.ising in the a.plica.ion of the effective ma.s theory to low dimensiona. na.ostructures.The theory results in a.system of coupled eigenva.ue PDEs tha. is usua.ly supplemented by interfa.e bounda.y conditions tha. ca. be derived from a.va.ia.iona. formula.ion of the problem.We a.a.yze such a.system for the envelope functions a.d show tha. a.fa.lure to restrict their Fourier expa.sion coeffi-cients to sma.l k components would lea. to the a.pea.a.ce of non-physica. solutions.We survey the existing methodologies to elimina.e this difficulty a.d propose a.simple a.d effective solution.This solution is demonstra.ed on a. exa.ple of a.two-ba.d model for both bulk ma.eria.s a.d low-dimensiona. na.ostructures.Fina.ly,ba.ed on the a.ove requirement of sma.l k,we derive a.model for na.ostructures with cylindrica. symmetry a.d a.ply the developed model to the a.a.ysis of qua.tum dots using a. eight-ba.d model.

Ba.kground &a.ms: Some pa.ients with ea.ly ga.troesopha.ea. ca.cer ma. a.pea. to “hea." beca.se of a.tisecretory medica.ion, but the risk of a.missed dia.nosis is unknown. The a.m of the study wa. to estima.e the incidence of ga.troesop ha.ea. ca.cer with or without pre-endoscopic trea.ment with a.tisecretory medica.ion. Methods: We extra.ted da.a.on use of endoscopies, ga.troesopha.ea. ca.cer dia.noses, dea.h, migra.ion, a.d use of a.tisecretory medica.ion (H2 blockers a.d proton pump inhibitors) from 5 popula.ion-ba.ed registries covering 1974-2002. We included a.l citizens in Funen County (popula.ion, 470,000) who between 1993 a.d 2002 were investiga.ed by endoscopy for the first time. The pa.ients were followed up until dea.h, emigra.ion, or the end of the study period. Results: a.ong 27,829 pa.ients with a.first endoscopy (mea. a.e, 56 yea.s; 48%ma.e, 115,804 person-yea.s of follow-up), 461 ha. ga.troesopha.ea. ca.cer dia.nosed a. the first endoscopy a.d 52 were dia.nosed during a.media. follow-up of 2.7 yea.s a.ter the first endoscopy. The incidence during follow-up wa. simila. to the ba.kground popula.ion (sta.da.dized incidence ra.io, 1.24; 95%confidence interva.l, 0.81-1.91), increa.ed with a.e, a.d wa. higher in ma.e pa.ients. The inciden ce of ga.troesopha.ea. ca.cer during follow-up wa. 46 per 100,000 person-yea.s in users of a.tisecretory medica.ion the la.t 180 da.s before the first endosco py compa.ed with 44 per 100,000 person-yea.s in nonusers (a.e a.d sex sta.da.di zed difference, 4 per 100,000 person-yea.s; 95%confidence interva., -14 to 22 ). Conclusions: Very few ca.cers a.e missed a. endoscopy. The risk seems simila. in users a.d nonusers of a.tisecretory medica.ion before endoscopy.
