Traffic flow models with phase transitions on road networks

open access: yesNetworks and Heterogeneous Media, 2009
The paper presents a review of the main analytical results available on the traffic flow model with phase transitionsdescribed in [10]. We also introduce a forthcoming existence result on road networks [14].

A riemann-hilbert problem in a riemann surface [PDF]

open access: yesActa Mathematica Scientia, 2011
Abstract One of the inspirations behind Peter Lax's interest in dispersive integrable systems, as the small dispersion parameter goes to zero, comes from systems of ODEs discretizing 1-dimensional compressible gas dynamics [17]. For example, an understanding of the asymptotic behavior of the Toda lattice in different regimes has been able to shed ...

Optimal Selling Mechanisms With Endogenous Seller Outside Offers

open access: yesInternational Economic Review, EarlyView.
ABSTRACT We examine a two‐stage selling mechanism design problem, where the buyer makes her report and the seller endogenously decides his effort (hidden investment) to generate a possibly better outside offer. The optimal mechanism shows that the seller's effort depends on the reported value of the buyer; a higher value lowers the seller's incentive ...

Tabulation of the Riemann problem solution in Godunov method for Soave – Redlich – Kwong equation of state [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика
The work is devoted to the using of the exact solutions of the Riemann problem on the decay of an arbitrary discontinuity to describe the real gases flows with the Soave – Redlich – Kwong equation of state.

Multivariate maternal effects across the internalizing–externalizing spectrum in childhood: results from the Norwegian mother, father, and child cohort study

open access: yesJournal of Child Psychology and Psychiatry, EarlyView.
Background From a functionalist perspective, parenting behaviors have adaptive functions and are partly expressions of genetic variation. Maternal genes that have effects on children are often referred to as indirect maternal genetic effects. Indirect genetic effects provide a means for measuring the role of parenting without the need for specifying ...

Revisiting PSF models: Unifying framework and high‐performance implementation

open access: yesJournal of Microscopy, EarlyView.
Abstract Localisation microscopy often relies on detailed models of point‐spread functions. For applications such as deconvolution or PSF engineering, accurate models for light propagation in imaging systems with a high numerical aperture are required. Different models have been proposed based on 2D Fourier transforms or 1D Bessel integrals.

Chronic insomnia, REM sleep instability and emotional dysregulation: A pathway to anxiety and depression?

open access: yesJournal 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.
