Pricing of Defaultable Securities in a Multi-Factor Quadratic Gaussian Model [PDF]
We present the multi-factor quadratic reduced form model for pricing of credit risky securities. We use quadratic Gaussian processes to model the short term interest rate and the intensity of default showing that we get tractable formulas for the price ...

Advanced Materials Technologies, EarlyView.A wet ball‐milling method is presented to synthesize iron magnetic nanoparticles and evaluate their magnetic hyperthermia performance. Optimized particles (∼270 nm, Ms ∼114 emu/g) achieve ∼50°C heating under clinically safe alternating magnetic fields, while pulsed‐field operation enables controlled temperature regulation (∼30°C).

Journal of Algebra, 1995 The author has been motivated by the wish to formulate the results of \textit{B. Alpers} [J. Algebra 137, 44-55 (1991; Zbl 0727.11017)]\ on round quadratic forms for quadratic forms instead of for elements of the Witt ring. The goal of this paper is finding a classification of round quadratic forms.

Advanced Optical Materials, EarlyView.Large Faraday rotation at room temperature is observed in thin films of discotic copper (Cu2+: 3d9) and vanadyl (VO2+: 3d1) enaminoketone complexes. The large Verdet constant originates from a high density of paramagnetic centers, metal‐ligand p−d hybridization and π orbitals involved in optical transitions (identified by DFT calculations), as well as ...

An algebraic approach to the Siegel-Weil average for binary quadratic forms [PDF]
, 2019 In this talk, we will consider the celebrated results of Siegel and Weil about the number of representations by the genus of a given positivedefinite integral quadratic form.

Advanced Optical Materials, EarlyView.Negatively charged boron vacancy defects in hexagonal boron nitride promise near‐surface quantum sensing, but their internal spin transition rates are only partly understood. This work directly measures the defect's singlet‐state lifetime, 15(3) ns, using a nanosecond rise‐time dual‐pulse photoluminescence‐recovery method, and shows that high laser ...

A response analysis of wheat and barley to nitrogen in Finland
Agricultural and Food Science, 1993 A nonlinear Mitscherlich function was found to be superior to quadratic and square root functions in estimating yield response to nitrogen based on a Finnish sample of barley.

Generating functions and short recursions, with applications to the moments of quadratic forms in noncentral normal vectors [PDF]
Using generating functions, the top-order zonal polynomials that occur in much distribution theory under normality can be recursively related to other symmetric functions (power-sum and elementary symmetric functions, Ruben, Hillier, Kan, and Wang ...

Embeddability of quadratic forms in Pfister forms
Indagationes Mathematicae, 2000 Let \(F\) be a field of characteristic not 2. An anisotropic quadratic form \(q\) over \(F\) is called \(m\)-embeddable if \(q\) is similar to a subform of an anisotropic \(m\)-fold Pfister form. Let \(m(q), m_{\text{ext}}(q)\), \(m_{ptr}(q)\) be the smallest integer \(m\) such that \(q\) is \(m\)-embeddable over \(F\), over an extension of \(F\), over
