In this study, the propagations of surface acoustic waves (SAWs) in two-dimensional solid/fluid phononic crystal (PC) structures were investigated.The PC structures are composed of a periodic sequence of hollow pillars deposited on a semi-infinite substrate, which can be filled with various kinds/heights of RAF Corner Chaise fluid.Finite element an
Background: A majority of patients with gastroesophageal reflux disease (GERD) have normal endoscopy.We aimed to investigate whether esophageal primary and secondary peristalsis influence esophageal reflux parameters in patients with normal endoscopy.Methods: We enrolled consecutive patients with typical reflux symptoms and normal endoscopy.All pat
Motivated to address the inconsistency between the essential i.i.d.assumption in machine learning theory and the data heterogeneity in real-world applications, we propose a novel calibrated ensemble (CE) algorithm to facilitate learning with diverse data subgroups.Unlike the traditional ensemble framework in which each learner is trained independen
Gender-based violence (GBV) is pervasive and enduring in Papua New Guinea (PNG).Women and girls in this country are to a PRO-ADD large extent exposed to sexual assault, rape and domestic violence in urban and rural areas.Once affected, they get only little attention and support, let alone justice.Asking what triggers violence against women in PNG t
