According to the adverse consequences that are brought by financial distress for companies, economy and financial –monetary institutions, the use of methods that can predict the occurrence of financial failure and prevent the loss of wealth is of great importance. The major models of credit risk assessment are based on retrospective information and using the methods which use the updated market...

Default risk is one of the most important types of risks, and credit default swap (CDS) is one of the most effective financial instruments to cover such risks. The lack of these instruments may reduce investment attraction, particularly for international investors, and impose potential losses on the economy of the countries lacking such financial instruments, among them, Iran. After the 2007 fi...

considering significant influence of financial crisis on the economy as a whole, policymakers spend remarkable resources on supervision and methods to ensure about sustainable financial system . a non-performing loan, or npl, is a loan that is in default or close to being in default. many loans become non-performing after being in default for 90 days, but this can depend on the contract termsan...

background: tuberculosis remains a worldwide public health problem and india accounts for highest tb burden in the world. the aim of the study was to evaluate the trend and treatment outcome of tuberculosis (tb) cases treated under dots strat­egy at a district level in karnataka, india. methods : this was a retrospective record based study conducted in dakshina kannada district of karnataka, du...

In this brief review, I argue that the impact of a stimulus on behavioral control increase as the distance of the stimulus to the body decreases. Habituation, i.e., decrement in response intensity repetition of the triggering stimulus, is the default state for sensory processing, and the likelihood of habituation is higher for distal stimuli. Sensitization, i.e., increment in response intensity...

Default Logic employs assumption-based default rules to draw plausible consequences in face of incomplete information. In ontology representation, there are two kinds of relations between concepts: subsumption relation and default subsumption relation. Subsumption relation is transitive, whereas default subsumption relation is transitive by default. Both default transitivity of default subsumpt...

This paper is about the fusion of multiple information sources represented using default logic. More precisely, the focus is on solving the problem that occurs when the standard-logic knowledge parts of the sources are contradictory, as default theories trivialize in this case. To overcome this problem, it is shown that replacing each formula belonging to Minimally Unsatisfiable Subformulas by ...

We investigate default probabilities and default correlations of Merton-type credit portfolio models in stress scenarios where a common risk factor is truncated. The analysis is performed in the class of elliptical distributions, a family of light-tailed to heavy-tailed distributions encompassing many distributions commonly found in financial modelling. It turns out that the asymptotic limit of...

Wrong way risk can be incorporated in Credit Value Adjustment (CVA) calculations in a reduced form model. Hull and White [16] introduced a CVA model that captures wrong way risk by expressing the stochastic intensity of a counterparty’s default time in terms of the financial institution’s credit exposure to the counterparty. We consider a class of reduced form CVA models that includes the formu...

Introduction. Intensity non-uniformity can have detrimental effect on the accuracy of automated measurements of brain structures and can often be corrected only retrospectively. Among existing correction approaches, the nonparametric non-uniformity intensity normalization method N3 (1) is one of the most frequently used. However, at least one recent study (2) suggested that its performance on 3...
