We investigate the credit risk model defined in Hatchett and Kühn [18] under more general assumptions, in particular using a general degree distribution for sparse graphs. Expanding upon earlier results, we show that the model is exactly solvable in the N →∞ limit and demonstrate that the exact solution is described by the message-passing approach outlined in Karrer and Newman [21], generalized...
Lars Harms-Ringdahl has a degree in Electrical Engineering from the Royal Institute of Technology in Stockholm, Sweden, where he also received his doctoral degree. He works at the Institute for Risk management and Safety analysis in Stockholm. His research is mainly directed at methodologies to prevent accidents and similar problems. Many of the projects have a focus on industrial and occupatio...
Background and Objective: Heavy metals contaminations are readily bioaccumulated in aquatic systems and lead to increased concentrations in food chains, posing a serious threat to human health, water-related organisms and aquatic ecosystems. The purpose of the present study was to determine the concentration of heavy metals in surface sediments of CheshmehKile River, to evaluate environmental a...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
compare the effect of different ceramic thicknesses on degree of conversion (dc) of 3 light-cured resin cements. methods: in this experimental in-vitro study, the degree of conversion of three light-cured resin cements, variolink veneer (ivoclar, liechtenstein), relyx veneer (3m espe, usa) and choice2 (bisco, usa) were evaluated beneath feldespatic ceramic discs (vita vmk master) with a same sh...
statement of problem: for many years, application of the composite restoration with a thickness less than 2 mm for achieving the minimum polymerization contraction and stress has been accepted as a principle. but through the recent development in dental material a group of resin based composites (rbcs) called bulk fill is introduced whose producers claim the possibility of achieving a good rest...
the current study examined iranian undergraduate efl students’ willingness to communicate with regard to their vocabulary knowledge. in general, participants were somewhat willing to communicate in english. the total mean score of 730 university students’ perception of willing to communicate was 83.53 out of 135. results, regarding four parts of willingness to communicate, revealed that part...
The most important aim of every project is on time completion, budget consideration and reaching the highest possible quality, based on contract. This paper suggests a methodology for risk management in engineering, procurement, and construction (EPC) projects. Risk management enables project teams to perform with minimum deviation from predetermined goals. The proposed methodology identifies a...
abstract breast cancer is a multifactorial disease. benign breast disease (bbd) is one of the most important risk factors for breast cancer. the etiology of bbd is unknown. it is divided into nonproliferative and proliferative diseases. the selection of studies will be based on titles, abstract screening, inclusion and exclusion criteria, and quality assessment. previous studies have shown that...
