On classification of global dynamics for energy‐critical equivariant harmonic map heat flows and radial nonlinear heat equation

Communications on Pure and Applied Mathematics, EarlyView.
Abstract We consider the global dynamics of finite energy solutions to energy‐critical equivariant harmonic map heat flow (HMHF) and radial nonlinear heat equation (NLH). It is known that any finite energy equivariant solutions to (HMHF) decompose into finitely many harmonic maps (bubbles) separated by scales and a body map, as approaching to the ...

Boundary conditions and universal finite‐size scaling for the hierarchical |φ|4$|\varphi |^4$ model in dimensions 4 and higher

Communications on Pure and Applied Mathematics, EarlyView.
Abstract We analyse and clarify the finite‐size scaling of the weakly‐coupled hierarchical n$n$‐component |φ|4$|\varphi |^4$ model for all integers n≥1$n \ge 1$ in all dimensions d≥4$d\ge 4$, for both free and periodic boundary conditions. For d>4$d>4$, we prove that for a volume of size Rd$R^{d}$ with periodic boundary conditions the infinite‐volume ...

AGORA: Adaptive Generation of Orthogonal Rational Approximations for Frequency‐Response Data

International Journal of Circuit Theory and Applications, EarlyView.
This paper introduces the adaptive generation of orthogonal rational approximations (AGORA) method for rational function approximation of measured or simulated microwave network parameters. AGORA allows estimating the model order for a given error tolerance and does not require any initial estimates or adjustment of hyperparameters. ABSTRACT This paper

Longitudinal Effects of Residential Treatment for Eating Disorders: Symptom Trajectories and Predictors of Functional Outcomes

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Residential treatment for eating disorders addresses the gap between inpatient and outpatient care, but evidence for longer‐term and functional outcomes remains limited. The current study examined both clinical and functional outcomes from admission to a 6‐month follow‐up from Australia's first residential service for eating ...

PTSD and Complex PTSD in Residential Treatment for Eating Disorders: Moderating Effects on Symptom Severity and Outcome Trajectory

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Eating disorders (EDs) and symptoms of trauma commonly co‐occur, yet research is limited on how trauma affects ED treatment outcomes. This is particularly true for complex post‐traumatic stress disorder (CPTSD). Differentiating between the treatment impacts of PTSD and CPTSD (which includes both PTSD symptoms and disturbances in self‐

Joint power control and user grouping mechanism for efficient uplink non‐orthogonal multiple access‐based 5G communication: Utilising the Lèvy‐flight firefly algorithm

IET Networks, EarlyView., 2023
We utilise a metaheuristic optimisation method, inspired by nature, called the Lévy‐flight firefly algorithm (LFA), to tackle the power regulation and user grouping in the NOMA systems. Abstract The non‐orthogonal multiple access strategies have shown promise to boost fifth generation and sixth generation wireless networks' spectral efficiency and ...

Weight Suppression, Binge Eating, and Purging as Predictors of Weight Gain During Inpatient Treatment in Persons With Bulimia Nervosa

European Eating Disorders Review, EarlyView.
ABSTRACT Objective Persons with bulimia nervosa (BN) often gain weight during treatment, which potentially poses a threat to treatment adherence. Although weight suppression has been found to be a predictor of weight gain in persons with BN, research about the trajectory of weight changes during treatment and other predictors thereof is scarce.

Processes and Predictions in Ecological Models: Logic and Causality

Journal of Forecasting, EarlyView.
ABSTRACT To make credible ecological predictions for terrestrial ecosystems in a changing environment and increase our understanding of ecological processes, we need plant ecological models that can be fitted to spatial and temporal ecological data.

Stock Return Prediction Based on a Functional Capital Asset Pricing Model

Journal of Forecasting, EarlyView.
ABSTRACT The capital asset pricing model (CAPM) is readily used to capture a linear relationship between the daily returns of an asset and a market index. We extend this model to an intraday high‐frequency setting by proposing a functional CAPM estimation approach.

Home‐Based Care Outcomes: Does the Care Provider Matter?

Health Economics, EarlyView.
ABSTRACT Long‐term services in the home are predominately provided by family or friends, with a growing proportion of individuals receiving formal care, or paid care by a professional, or a combination of both. However, the relative benefits to the care recipient of who provides the care are largely unknown.
