Real‐Time Conformal Maps and Parameterizations
Computer Graphics Forum, EarlyView.Abstract We present a simple algorithm to conformally map between two simple and bounded planar domains based on the concept of harmonic measure, which is a conformal invariant. With suitable preprocessing, the algorithm is fast enough to compute all possible conformal maps (having three real degrees of freedom) between the two domains in real time in

Difference and the Liberation of Sufficient Reason
European Journal of Philosophy, EarlyView.Abstract The Principle of Sufficient Reason (PSR) holds that every event and entity can be explained by a sufficient reason or cause. Philosophers have long struggled with the question of the PSR's compatibility with freedom, for if what occurs or exists follows necessarily from its sufficient reason then it seems it could not have been otherwise ...

Вестник Самарского университета: Естественнонаучная серияBoundary value problems for certain systems of hyperbolic-type differential equations can be effectively solved using the Riemann method. In this paper, we consider an approach for constructing the Riemann matrix for a system of fourth order hyperbolic ...

International Social Science Journal, EarlyView.ABSTRACT This article examines the British government's response to the August 2011 English riots through the lens of state crime, drawing on Richards and Avery's ‘Thug State’ concept. It addresses the relative neglect of the state's response itself as a potential form of criminality and social harm.

On Riemann method for solving a mixed problem
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2007 The formula for solution of a problem for an equation with the higher partial derivative of the general type is constructed using Riemann method. In this problem the solution is found in the characteristic parallelepiped with separated by the non ...

Contingent capital: A tale of two valuations
Journal of Risk and Insurance, EarlyView.Abstract This study investigates the valuation gap between buyers and sellers of insurers' contingent capital, driven by asymmetric exposures to tax benefits, capital injections, and bankruptcy costs. We develop a novel Twin‐Tree Model with Jumps (TTMJ) that models the insurer's asset value dynamics by incorporating catastrophe risk, insolvency risk ...

Journal of Sleep Research, Volume 34, Issue 2, April 2025.Summary The world‐wide prevalence of insomnia disorder reaches up to 10% of the adult population. Women are more often afflicted than men, and insomnia disorder is a risk factor for somatic and mental illness, especially depression and anxiety disorders.
