Prevalence of Dental Caries in Persons With or Without Long‐Term Experience of Positive Airway Pressure‐Treated Obstructive Sleep Apnoea

International Journal of Dental Hygiene, EarlyView.
ABSTRACT Oral dryness is common in persons with untreated obstructive sleep apnoea (OSA) as well as in those using positive airway pressure (PAP). OSA with or without PAP treatment could therefore be a risk factor of dental caries. Objectives To describe and compare the prevalence of dental caries among persons with or without PAP‐treated OSA.

Generating Synthetic Data Using 2D Multifractal Detrended Fluctuation Analysis Generative Adversarial Networks

IEEE Access
A novel 2-dimensional Multifractal Detrended Fluctuation Analysis (2D-MFDFA) as a discriminator for Generative Adversarial Networks (GAN) is presented in this work. The proposed approach demonstrates improved generated data quality at early iterations on

Multifractal Detrended Fluctuation Analysis Combined with Allen–Cahn Equation for Image Segmentation

Fractal and Fractional
This study proposes a novel image segmentation method, MF-DFA combined with the Allen–Cahn equation (MF-AC-DFA). By utilizing the Allen–Cahn equation instead of the least squares method employed in traditional MF-DFA for fitting, the accuracy and ...

One‐Way Versus Two‐Way Postacquisition Integration Efforts: Theory and Evidence

Journal of Economics &Management Strategy, EarlyView.
ABSTRACT We develop a theory of postacquisition integration that distinguishes between one‐way (acquirer‐only) and two‐way (mutual) effort strategies. We argue that the method of payment—cash versus shares—may serve as an ex ante commitment mechanism to a particular integration strategy, where cash deals align with unilateral effort, and share deals ...
