Well-posedness of discontinuous boundary-value problems for nonlinear elliptic complex equations in multiply connected domains

Electronic Journal of Differential Equations, 2013
In the first part of this article, we study a discontinuous Riemann-Hilbert problem for nonlinear uniformly elliptic complex equations of first order in multiply connected domains. First we show its well-posedness. Then we give the representation of

Improving access to help with poor sleep across youth mental health services: Interim implementation and clinical outcomes

British Journal of Clinical Psychology, EarlyView.
Abstract Objectives There is a high, unmet sleep need in young people with mental health difficulties. We took a whole‐system approach to improving access to sleep support across a youth mental health system (14–25 years). Methods We used the Exploration, Preparation, Implementation and Sustainment (EPIS) framework to develop an implementation ...

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

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 ...

Optimal Selling Mechanisms With Endogenous Seller Outside Offers

International 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 ...

A Riemann–Hilbert approach to solution of the modified focusing complex short pulse equation

Frontiers in Applied Mathematics and Statistics
We develop a Riemann–Hilbert approach to the modified focusing complex short pulse (mfcSP) equationuxt=u+12u¯(u2)xxwith zero boundary conditions (as |x| → ∞).

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

Journal 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 ...

Time‐dependent association between prenatal hair glucocorticoid levels and child behavior problems

Journal of Child Psychology and Psychiatry, EarlyView.
Background Child internalizing and externalizing behavioral problems are highly prevalent psychiatric symptoms worldwide, for which maternal prenatal stress is a known risk factor. However, underlying neuroendocrine mechanisms remain largely unclear. We investigated whether maternal hair cortisol (HCC) and cortisone concentration (HCNC) are associated ...

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

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.
