We show that exposure from past business transactions – risk overhang – can reduce activity in related business lines, sometimes to the point where no new trade occurs. We focus primarily on the role of overhang in nonlife insurance market disruptions. Our model predicts that the relative impact, duration, and character of supply disruptions are related to the extent of overhang. These predicti...
A permutation π is said to be a Dumont permutation of the first kind if each even integer in π must be followed by a smaller integer, and each odd integer is either followed by a larger integer or is the last element of π (see, for example, www.theory.csc.uvic.ca/∼cos/inf/perm/Genocchi Info.html). In Duke Math. J. 41 (1974), 305–318, Dumont showed that certain classes of permutations on n lette...
Knockout mouse models targeting various cytochrome P450 (P450 or CYP) genes are valuable for determining P450’s biologic functions, including roles in drug metabolism and chemical toxicity. In this study, a novel Cyp2a(4/5)bgs-null mouse model was generated, in which a 1.2-megabase pair genomic fragment containing nine Cyp genes in mouse chromosome 7 (including, sequentially, Cyp2a5, 2g1, 2b19,...
pregnancy in the rudimentary horn of uterus is rare. uterine rupture is a rare obstetrical catastrophe that occurs before 20 weeks’ gestation in 70% of unicornate uterus cases. a 24-year-old primigravida woman was referred to our hospital due to failed induction-in-17th-weeks-of-her-pregnancy. fetal-death was confirmed on abdominal ultrasound. examination under-anaesthesia revealed -pregnancy-i...
