Essays on Credit Risk

This dissertation covers the issues related to credit risk that stem from the recent financial crisis and that are concerned by investors, financial intermediaries, and governments. The results of the research have important implications for asset managers, such as using the information from the credit risk market to rebalance stock portfolios, and for policy makers in regulating or bailing out ba

Mchf Calculations For Atomic Properties

A historical review of the early development of Hartree-Fock and Multiconfiguration Hartree-Fock theories is presented. After the underlying theory is summarized, some recent results from the application of these methods to the prediction of atomic properties are described. These include total energies, transition probabilities, autoionization rates, specific mass shifts, and hyperfine parameters.

Planning for multilingualism and minority language rights in Sweden

As the presence of English in Europe continues to grow, there is a mounting interest in the position of national languages among European institutions, societies, and people. Swedish, like many national languages in Europe and throughout the world, is in an awkward position. It is at the same time a strong national language with the potential to dominate other languages within national borders and

Tensile Strength of Surgical Knots Performed with the da Vinci Surgical Robot.

The objective of this study was to estimate the tensile strength of surgical knots made using the da Vinci robot. Four different types of flat square knots (strand-to-strand 4 throw, strand-to-strand 6 throw, loop-to-strand 4 throw, and loop-to-strand 6 throw) were made using the da Vinci-S system by 4 different surgeons, all experienced with the system. For the knots, we used braided polyglactin

Emotional disorders in testicular cancer survivors in relation to hypogonadism, androgen receptor polymorphism and treatment modality.

PURPOSE: It has been documented that testicular germ cell cancer (TGCC) patients may be at increased risk of developing emotional distress (EMD). Hence, the aim of the present study was to investigate whether EMD is related to the presence of hypogonadism, androgen receptor (AR) polymorphism and/or treatment intensity. PATIENTS AND METHODS: Three to five years after treatment, testosterone and lut

Importance of standardized assessment of late gadolinium enhancement for quantification of infarct size by cardiac magnetic resonance: implications for comparison with electrocardiogram.

BACKGROUND: Cardiac magnetic resonance (CMR) is currently considered the reference standard for in vivo assessment of myocardial infarction (MI). There is, however, no international consensus on how MI quantification from CMR should be performed. The aim of this study was to test how previously published manual quantification of MI using CMR images compares with MI quantification using a semiautom

Is contact allergy to disperse dyes and related substances associated with textile dermatitis?

Summary Background Disperse dyes (DDs) are the most common sensitizers among textile dyes, but there is little knowledge of the clinical relevance of positive patch test reactions. Objective To investigate if patient-reported textile-related skin problems can be explained by contact allergy to eight different DDs and/or to chemically related substances, by occupation or by atopic constitution, and

Pre-Emptive Treatment With Rituximab of Molecular Relapse After Autologous Stem Cell Transplantation in Mantle Cell Lymphoma.

PURPOSE: Minimal residual disease (MRD) is predictive of clinical progression in mantle-cell lymphoma (MCL). According to the Nordic MCL-2 protocol we prospectively analyzed the efficacy of pre-emptive treatment using rituximab to MCL patients in molecular relapse after autologous stem cell transplantation (ASCT). Patients and Materials: MCL patients enrolled in the study, who had polymerase chain

In vivo transport of Gd-DTPA(2-) in human knee cartilage assessed by depth-wise dGEMRIC analysis.

PURPOSE: To investigate the transport of Gd-DTPA(2-) in different layers of femoral knee cartilage in vivo. MATERIALS AND METHODS: T(1) measurements (1.5 Tesla) were performed in femoral knee cartilage of 23 healthy volunteers. The weight-bearing central cartilage was analyzed before contrast and at eight time points after an intravenous injection of Gd-DTPA(2-) : 12-60 min (4 volunteers) and 1-4

Gender differences in outcome after stent treatment of lesions in the femoropopliteal segment.

Background and Aims: Although endovascular stent treatment is increasingly used in infrain-guinal atherosclerotic occlusive disease, outcome with focus on gender differences has not been reported in detail. Material and Methods: One hundred and twelve consecutive patients (67 [60%]) women, un-dergoing endovascular nitinol stent treatment of atherosclerotic lesions in the femoropopliteal segment

Who should have knee joint replacement surgery for osteoarthritis?

Knee joint replacement is an effective and cost-effective intervention for severe symptomatic osteoarthritis of the knee joint. However, utilisation rates vary hugely, there are no indications, it is difficult to know when (in the course of arthritis) it is best to operate, and some 10-20% of people who have this surgery are unhappy with the outcome, and have persistent pain. In this article we br

Optical properties, durability, and system aspects of a new aluminium-laminated steel reflector for solar cocentrators

A newly developed aluminium-polymer-laminated steel reflector for use in solar concentrators was evaluated with respect to its optical properties, durability, and reflector performance in solar thermal and photovoltaic systems. The optical properties of the reflector material were investigated using spectrophotometer and scatterometry. The durability of the reflector was tested in a climatic test

A 3-level asynchronous protocol for a differential two-wire communication link

A differential two-wire communication link with a 3-level asynchronous protocol is introduced. The proposed 3-level code contains information of both data and clock. Since only one edge is needed for each bit, the bandwidth of a link is efficiently utilized. The power consumption is reduced by the low-swing differential two-wire link and is further reduced by a 3-level code. The speed of the proto
