Non-topological solitons have been studied in a variety of models [1]. One particular type of such solitons, Q-balls [1,2], are present in the spectrum of a theory, whenever it satisfies the conditions outlined below. This class of theories includes the MSSM and other supersymmetric generalizations of the Standard Model. Surprisingly, the rich phenomenology associated with the solitonic sector ...

BACKGROUND AND OBJECTIVES Gastric bezoars are a rare clinical entity, most commonly observed in patients with mental or emotional illness. Large bezoars can be difficult to remove laparoscopically without extending a port incision. METHODS We report the case of a large symptomatic trichobezoar with Rapunzel syndrome that occurred in a 17-year-old girl who had trichotillomania. RESULTS The b...

1 Greg Kirk[Ki] raised the question of comparing the following two ways for labelling balls. Given r predetermined positive integers n i , (1 ≤ i ≤ r), and given N balls (N large), consider two ways to randomly assign r− component vectors of integers (a 1 ,. .. , a r) to them, such that 1 ≤ a i ≤ n i. We will call these vectors 'labels'. Of course altogether there are r i=1 n i possible labels....
