In this paper we consider a Black and Scholes economy and investigate two approaches to hedging contingent claims. We show that the general Malliavin calculus approach can generate the classical Delta-hedging formula under weaker conditions.

Objective: To evaluate whether pregnancies with infants affected by congenital heart defects are associated with adverse obstetric and perinatal outcome. Study design: In a prospective population-based cohort study from Sweden (1992-2001), 6346 singleton pregnancies with infants affected by congenital heart defects were, after suitable adjustments, compared to all delivered women. Results: The pre

The feasibility of willow short rotation coppice (SRC) for energy production as a revaluation tool for severely radiocaesium-contaminated land was studied. The effects of crop age, clone and soil type on the radiocaesium. levels in the wood were assessed following sampling in 14 existing willow SRC fields, planted on radiocaesium-contaminated land in Sweden following Chernobyl deposition. There wa

Approximately 5% to 10% of melanoma may be hereditary in nature, and about 2% of melanoma can be specifically attributed to pathogenic germline mutations in cyclin-dependent kinase inhibitor 2A (CDKN2A). To appropriately identify the small proportion of patients Who benefit most from referral to a genetics specialist for consideration of genetic testing for CDKN2A, We have reviewed available publi

Mechanically strong and flexible membranes with very high local concentrations of immobilized proton-conducting phosphonic acid have been achieved by grafting poly(vinylphosphonic acid) side chains onto polysulfones. The graft copolymers were prepared by anionic polymerization of diethyl vinylphosphonate initiated from lithiated polysulfones, followed by quantitative cleavage of the ester function

Female mate-choice based on genetic compatibility is an area of growing interest. The major histocompatibility complex (MHC) genes are likely candidates for such mate-choice since these highly polymorphic genes may both increase offspring viability and also provide direct cues for mate-choice. In great reed warblers, females actively choose a breeding partner out of a handful of males that they vi

In a population of 956 women, attending for contraceptive advice, 131 (13.7%) were found to have BV acording to Amsel's criteria. Clue cells were detected in 200 (20.9%) women, a positive amine ('sniff') test in 191 (20.0%), a vaginal pH > or = 4.7 in 243 (25.4%) and a "characteristic" vaginal discharge in 104 (10.9%) women. Sensitivity, specificity, positive and negative predictive values in rela

A balance sheet of the Cuban Revolution in terms of growth performance, equity, and the satisfaction of basic needs after 50 years is a mixed bag. Growth performance has been disappointing during most of the past 25 years, although there are today some encouraging new trends. Income distribution that was quite equal in 1985 has seen some deterioration since 1990. Agriculture has been one of the fa

Chlorophyll a (Chl a) serves a dual role in oxygenic photosynthesis: in light harvesting as well as in converting energy of absorbed photons to chemical energy. No other Chl is as omnipresent in oxygenic photosynthesis as is Chl a, and this is particularly true if we include Chl a2, (=[8-vinyl]-Chl a), which occurs in Prochlorococcus, as a type of Chl a. One exception to this near universal patter

Increased activity in the sympathetic nervous system is part of the physiological stress response and is expressed in the heart rate variability (HRV). The objective of this study was to examine associations of HRV and intima media thickness (IMT). In 2002, satisfactory measurements of HRV of 78 voluntary participants were made, both during a stress test and during sleep. IMT in 2002 and the progr

Artikeln ”Facklig styrka eller reformistisk strategi?” publicerades i Zenit nr 4 (nr 86) 1984 som en kommentar till Anders Perssons recension i Zenit nr 2 (nr 84) 1984 av Anders Kjellbergs doktorsavhandling Facklig organisering i tolv länder (Lund: Arkiv förlag 1983). Redaktionen klippte dock av utrymmesskäl bort ett stycke som under rubriken ”Facklig styrka – än en gång!” publicerades i Zenit nr

By putting emphasis on applications in two basic statistics courses for chemistry students and chemical engineering students we have enhanced student motivation and increased student activity. In addition to a traditional in-class exam, the students complete a take-home project where statistical problems relevant to chemists are discussed. We give several examples of the course and project materia

Objective To examine prospectively whether inflammatory biomarkers and endothelin (ET)-1 are increased in patients with renal artery stenosis (RAS), and to investigate how treatment with percutaneous transluminal renal angioplasty (PTRA) affects these variables during the first month after intervention. Methods One hundred patients with suspected RAS undergoing renal angiography were included. PTR

Utsikter - föreläsnngar från Helgonabacken ("Views - Lectures from Helgonabacken" consists of public lectures by teachers at the Department for Comparative Literature, Lund university. Most of the lectures deal with contemporary Swedish literature, but there are also texts on Italian and Danish poetry and American cinema.

Connections between interpolation spaces, Pick functions, and matrix monotone functions are investigated. Characterizations, inclusion results, open problems, and conjectures on these function classes and their interrelations are presented.

A general and somewhat popularized introduction to the Consuetudines Lundenses, i.e. the customary of the cathedral chapter of early twelfth-century Lund, its employment, and content.
