Princeton University Let H = -d2/dx2 + P(x) on L2(W, dx) and let E = inf spec ( H ) . Let be a normalized vector with H a = E n . Let q(t)be the Markov process with generator G = a-l(H E ) a , which is a Brownian motion with drift. We investigate behavior of q(t)as t oo and in particular prove that if P(x)= azmx2m + . . + ao; azm > 0, then lim supt,, 1if'q(s) ds/(ln t)'Izm = ( ~ z m ) ' / ~ ~

Plastic debris in the marine environment is widely documented, but the quantity of plastic entering the ocean from waste generated on land is unknown. By linking worldwide data on solid waste, population density, and economic status, we estimated the mass of land-based plastic waste entering the ocean. We calculate that 275 million metric tons (MT) of plastic waste was generated in 192 coastal ...

aim : the aim of current study is to investigate whether tonsillar and/or adenoid tissue of patients with chronic adenotonsillitis plays a reservoir role for helicobacter pylori (h. pylori) or helicobacter hepaticus ( h. hepaticus ). background : recently, there have been arguments ragarding helicobacter pylori ( h. pylori ) being reserved in adenotonsillar tissue. patients and methods : this s...

UNLABELLED It is well known that mouth breathing is associated with adenotonsillar hypertrophy - which is the main cause of obstructive sleep apnea among children. Despite the importance of this matter, there are only a handful of studies showing the relationship between OSAS and mouth breathing. AIM to determine the prevalence of obstructive sleep disorders in mouth breathing children and st...
