The paper tests the hypothesis that highly leveraged firms lose market shares to their less leveraged rivals in an industry downturn. Both parametric and semiparametric regression methods are applied to analyse the relationships between firm performance and leverage. It is found that the highly leveraged firms in distressed industries face relatively lower sales growth and stock returns but are st
Fatigue crack propagation in circular Ti-6Al-4V specimens subjected to high strain amplitudes has been investigated. Crack closure was measured with an electrical potential-drop technique. Closure was shown not to depend on strain ratio but to be a function of the applied strain range. At higher strain ranges, the crack was found to be closed for a smaller part of the load cycle than at lower stra
Results from quantum chemical calculations that predict the existence of a series of diuranium molecules are reported. Two diuranium chlorides, U2Cl6 and U2Cl82-, and three different carboxylates, U-2(OCHO)(4), U-2(OCHO)(6), and U-2(OCHO)(4)Cl-2 have been studied. All species have been found to be stable with a multiply bonded U-2 unit.
We make a thorough comparison between different schemes of merging fixed-order tree-level matrix element generators with parton-shower models. We use the most basic benchmark of the O(alpha_S) correction to e+e- -> jets, where the simple kinematics allows us to study in detail the transition between the matrix-element and parton-shower regions. We find that the CKKW-based schemes give a reasonably
Abstract The yeast Saccharomyces kluyveri (Lachancea kluyveri), a far relative of Saccharomyces cerevisiae, is not a widely studied organism in the laboratory. However, significant contributions to the understanding of nucleic acid precursors degradation in eukaryotes have been made using this model organism. Here we review eukaryotic pyrimidine degradation with emphasis on the contributions made
AIM: To infect mice with atypical Campylobacter concisus (C concisus) for the first time. METHODS: Three separate experiments were conducted in order to screen the ability of five clinical C concisus isolates of intestinal origin and the ATCC 33237 type strain of oral origin to colonize and produce infection in immunocompetent BALB/cA mice. The majority of the BALB/cA mice were treated with cyclop
The objective of this article reflects upon the isomorphic relationship between ideas across disciplines. In this instance we are considering the value of a well established methodology, cross methodology, adopted from macroeconomics and ideas from political science. The cross methodology is used as a means of considering the relationship between data collected for security purposes and individual
Combined treatment with electroremediation and sulphate reducing bacteria (SRB) was tested in laboratory and pilot scale. The contaminated soil came from a chlor-alkali factory and contained about 100 mg/kg Hg. Iodide/iodine complexing agent was used to mobilize mercury. Mercury iodide complexes were moved to the anode solution using an electric field. The anode solution was then mixed with hydrog
Background Screening for cervical cancer based on testing for human papillomavirus (HPV) increases the sensitivity of detection of high-grade (grade 2 or 3) cervical intraepithelial neoplasia, but whether this gain represents overdiagnosis or protection against future high-grade cervical epithelial neoplasia or cervical cancer is unknown. Methods In a population-based screening program in Sweden,
Genital ulceration is today often thought to be caused by herpes simplex. In this case report, a rare differential diagnosis, ulcus vulvae acutum is described, probably caused by Epstein–Barr virus (EB-virus).
Purpose: To assess the additional value of subtraction ictal single-photon emission computed tomography (SPECT) coregistered to MRI (SISCOM) for localization of the epileptogenic zone in patients with drug-resistant epilepsy scheduled for invasive video-EEG (VEEG) before epilepsy surgery by a descriptive study from clinical practice. Methods: Forty-nine consecutive epilepsy patients between Januar
In order to investigate what factors influence antibiotic prescribing, a questionnaire answered by 8700 parents to 4-year-old children in Malmö between 1999 and 2004 was analyzed. 51.3% of the 4-year-old children had been treated with antibiotics. Exposure to environmental smoking, attending day care centers, employment of parents and parents born in Sweden was found to be statistically significan
We discuss how techniques from multiresolution analysis and phase space transforms can be exploited in solving a general class of evolution equations with limited smoothness. We have wave propagation in media of limited smoothness in mind. The frame that appears naturally in this context belongs to the family of frames of curvelets. The construction considered here implies a full-wave description
Various types of graph statistics for graphs and digraphs are presented as numerators of incomplete U-statistics, with symmetric and asymmetric kernels, respectively. Thus, asymptotic Poisson limits of these statistics are provided by using limit theorems for the sums of dissociated random variables. Several applications to statistical analysis of graphs are given
The aim of this study was to analyse the mechanical behaviour of paperboard packages subjected to static compressive loads. The study was divided in three parts and experiments and finite element analysis conducted for each part. First, a panel of paperboard was subjected to edge compressive loading as a means of checking the material model. Second, the package was cut into segments and each segme
The subjects of this article are Kozhevnikov and Chistovitch's finding regarding the constancy of relative syllable durations and the inconstancy of relative speech sound durations for different rates of speech, and their proposal that vowels are elided because the necessary minimum duration of a consonant consumes all the time that happens to have been assigned to the syllable. The relative cons
