We compute optical properties including excitonic effects for the equilibrium polymorphs of three group-II metal monoxides by solving the Bethe-Salpeter equation. The underlying electronic structures are based on results of a recently developed GW approach starting from a hybrid exchange-correlation functional. The resulting quasiparticle band structures are discussed with respect to their mapp...

Context: Cadmium oxide nanoparticles (CdO NPs) are employed in optoelectronic devices and as a starting material for generating quantum dots as well as for medical imaging and targeting of pharmaceutical agents to disease sites. However, there are lack of data concerning shortand long-term effects of CdO NPs on the lungs. Objective: To determine the effects of inhaled CdO NPs at an occupational...

In this paper, we address the crucial problems of parameters estimation of Collateralized Debt Obligation (CDO). We present a methodology for fair spread estimation of reconstituted (CDO) from European market data. A fundamental part of the pricing framework is the estimation of default probabilities and the structure of dependency. We present a copula based simulation procedure for pricing CDO...

The title compound, {(C(2)H(10)N(2))[Cd(2)(HPO(4))(3)]·H(2)O}(n), was synthesized under hydro-thermal conditions. The structure of this hybrid compound consists of CdO(6), CdO(5) and PO(4) polyhedra arranged so as to build an anionic inorganic layer, namely [Cd(2)(HPO(4))(3)](2-), parallel to the ab plane. The edge-sharing CdO(6) octa-hedra form infinite chains running along the a axis and are ...

Most unsupervised image anomaly localization methods suffer from overgeneralization because of the high generalization abilities convolutional neural networks, leading to unreliable predictions. To mitigate overgeneralization, this study proposes collaboratively optimize normal and abnormal feature distributions with assistance synthetic anomalies, namely collaborative discrepancy optimization ...

The revaluation of collateralized debt obligations (CDOs) plays a significant role in the ongoing 2007-2009 credit crisis. Starting in August 2007, a large amount of initially AAA rated CDO securities are substantially downgraded, some directly to junk grade. This paper explores two structural sources of CDO mispricing: modeling difficulty and data limitation. Simulating the frailty correlated ...

cadmium oxide (cdo) nanoparticles were prepared by precipitation method using cadmium acetate and ammonia solution. presence of chemical species, were verified by fourier transform infra red (ftir) spectrum. from x-ray diffraction (xrd) spectrum the particle size, d-spacing value and structure of the nanoparticle were analysed. size of the nanoparticles and the elemental composition were detect...

We report the mechanical and tribological properties of transparent conductive oxide CdO+SnO2 coatings. The films were deposited on glass substrates by the sol-gel technique using, as precursor solution, a mixture of CdO and SnO2 solutions obtained at room temperature. Depending on the Sn atomic concentration percentage values the X-ray diffraction patterns show three types of films constituted...
