We consider the standard Credit Default Swap (CDS) payoff and some alternative approximated versions, stemming from different conventions on the premium and protection legs. We consider standard running CDS (RCDS), upfront CDS and postponed-payments running CDS (PRCDS). Each different definition implies a different definition of forward CDS rate, which we consider with some detail. We introduce...

BACKGROUND The Cardiac Depression Scale (CDS) is a disease-specific instrument for measuring depression in cardiac patients. This study was designed to validate the CDS in an Iranian population. METHODS Translation and back-translation of the 26-item CDS scale was performed using recommended procedures. The Iranian translation of the CDS (I-CDS) was administered to 261 individuals in Iran, co...

Connected-dominating-set (CDS) is a representative technique for constructing a virtual backbone of wireless networks. Most of existing works on CDS aim at minimizing the size of the CDS, i.e., constructing the minimum CDS (MCDS), so as to reduce the communication overhead over the CDS. However, MCDS may not work well in cognitive radio networks (CRNs) where communication links are prone to fai...

Cadmium Sulphide (CdS) nanoparticles were prepared using microemulsion method using cadmium chloride as cadmium source and sodium sulphide as sulphur source. The obtained nanoparticles structures were characterized by X-ray diffraction (XRD) and Transmission Electron Microscopy (TEM) whereas optical characterization was done by Ultra Violet-Visible absorption. XRD result shows that CdS nanopart...

BACKGROUND AND PURPOSE Color Doppler sonography (CDS) suffers from such disadvantages as high interobserver variability and problems with data presentation and storage. We therefore performed a prospective trial to assess the role of three-dimensional CDS (3D-CDS) in the evaluation of internal carotid artery stenosis (ICAS). METHODS We included 32 consecutive patients with sonographically ver...

In this work we report the synthesis and characterization of hybrid nanostructures of multiwall carbon nanotubes (MWCNT) and cadmium sulphide (CdS) nanoparticles. In a solution of thioacetamide and cadmium sulphide, purified MWCNT are added to prepare the CNT/CdS hetrostructure. XRD diagrams, SEM images, and also photoluminescence spectra of the prepared samples are analyzed. SEM images show th...

In this contribution, we report the synthesis of CdS nanoparticles directly conjugated to an enzyme, R-chymotrypsin (CHT) by chemical reduction in aqueous solution. Matrix-assisted laser desorption ionization (MALDI) mass spectrometry confirms the strong conjugation of CdS nanoparticles to CHT through covalent bonding in the CdS-CHT conjugates. High-resolution transmission electron microscopy (...

In this work we performed a detailed investigation of the photostability of bottom-up produced carbon nanodots (CDs) prepared from citric acid and urea by solvothermal synthesis. Analytical ultracentrifugation (AUC) reveals that the CDs have a hydrodynamic diameter of <1 nm and a very narrow size distribution. In the community it is widely assumed that CDs are photo-stable. In contrast, we foun...
