Subdiffusive Source Sensing by a Regional Detection Method

Sensors, 2019
Motivated by the fact that the danger may increase if the source of pollution problem remains unknown, in this paper, we study the source sensing problem for subdiffusion processes governed by time fractional diffusion systems based on a limited number ...

Numerical method of the exact control for the elastic string problem with moving boundary

Boletim da Sociedade Paranaense de Matemática
The objective of this article is to investigate, analytically and numerically, the exact control problem associated with a mathematical model that describes the vertical vibrations of elastic strings, with moving contours.

Understanding the Association Between Autistic Traits, Anorexia Nervosa Symptomatology and Weight Recovery in Female Adolescents: A Longitudinal Analysis

European Eating Disorders Review, EarlyView.
ABSTRACT Introduction Anorexia nervosa (AN) and autism are distinct conditions, yet individuals with AN often exhibit elevated autistic traits. These traits are linked to complex clinical presentations, but their impact on AN remains unclear. This longitudinal study investigates associations between autistic traits, AN symptoms, and weight recovery in ...

Solving and classifying the solutions of the Yang-Baxter equation through a differential approach. Two-state systems

Journal of High Energy Physics, 2018
The formal derivatives of the Yang-Baxter equation with respect to its spectral parameters, evaluated at some fixed point of these parameters, provide us with two systems of differential equations.

A Systematic Scoping Review of Factors Contributing to Loss of Control Eating During Pregnancy

European Eating Disorders Review, EarlyView.
ABSTRACT Objective Evidence suggests loss of control eating (LOC) during pregnancy is prevalent and linked to adverse health consequences for birthing individuals and their offspring; however, factors underlying risk for prenatal LOC remain unclear.

Internal exact controllability and uniform decay rates for a model of dynamical elasticity equations for incompressible materials with a pressure term

Electronic Journal of Qualitative Theory of Differential Equations, 2018
This paper is concerned with the internal exact controllability of the following model of dynamical elasticity equations for incompressible materials with a pressure term, $$\phi''-\Delta \phi=-\nabla p,$$ and it is also devoted to the study of the ...

Are Mental Health Symptoms of Parents of Young People Accessing Treatment for Eating Disorders Associated With Accommodating and Enabling Behaviours?

European Eating Disorders Review, EarlyView.
ABSTRACT Background Parental and family factors influence treatment outcomes of adolescents with eating disorders (EDs), particularly in family‐based interventions. However, little is known about how parental mental health is associated with well‐established factors that influence treatment outcomes.

A Deep Learning Framework for Forecasting Medium‐Term Covariance in Multiasset Portfolios

Journal of Forecasting, EarlyView.
ABSTRACT Forecasting the covariance matrix of asset returns is central to portfolio construction, risk management, and asset pricing. However, most existing models struggle at medium‐term horizons, several weeks to months, where shifting market regimes and slower dynamics prevail.

Exact controllability for a string equation in domains with moving boundary in one dimension

Electronic Journal of Differential Equations, 2015
We consider a string equation in a domain with moving boundary. By using the multiplier method in non-cylindrical domains, we establish the exact boundary controllability in domains with moving boundary, and obtain a weaker condition on the time ...

Quadratic Hedging of American Options Under GARCH Models

Journal of Futures Markets, EarlyView.
ABSTRACT American options are widely traded in financial markets, yet there is a scarcity of literature on hedging in incomplete markets. In this paper, we derive optimal hedging ratios and option values using Local Risk Minimization (LRM) and Global Risk Minimization (GRM) hedging strategies through dynamic programming.
