The bubble departure radius is a very important parameter for bubble dynamics during boiling heat transfer. In this study, experiments of highly subcooled nucleate pool boiling of FC-72 were conducted on two different sized silicon chips (chip S 2×2 and chip S 1×1) in short-term microgravity and normal gravity conditions by utilizing the drop tower in Beijing. During the experimental study, bubble
Introduction/Objectives: The meta-analytical prevalence of paternal postnatal depression (PPND) is 8.4% (Cameron et al., 2016). However, measures for PPND are scarce and the commonly used Edinburgh Postnatal Depression Scale (EPDS) has low sensitivity, as many men express depression with somatization and/or externalizing symptoms. Recent studies show higher prevalences, indicating that affected me
Analysis of signals defined on complex topologies modeled by graphs is a topic of increasing interest. Signal decomposition plays a crucial role in the representation and processing of such information, in particular, to process graph signals based on notions of scale (e.g., coarse to fine). The graph spectrum is more irregular than for conventional domains; i.e., it is influenced by graph topolog
This article explores the representation of Daoism and Chinese religion in the writings of Aleister Crowley. The influence of Asian religions on the occult revival of the late nineteenth century has often been recognized. Even though much has been said about the perception of Indian religious traditions in European and American esotericism, the influence of Chinese religion on the same environment

The morphology of the internal organs of two representative species of the crustacean classes Mystacocarida, Derocheilocaris typica (Pennak & Zinn, 1943), and Cephalocarida, Hutchinsoniella macracantha (Sanders, 1955), has been studied ultrastructurally from 1990 onwards. A review of the subject offers a unique opportunity to compare and contrast the two taxa at a time when their key positions
In multiuser multiple–input multiple–output (MU–MIMO) systems, channel correlation is detrimental to system performance. We demonstrate that widely used, yet overly simplified, correlation models that generate identical correlation profiles for each terminal tend to severely underestimate the system performance. In sharp contrast, more physically motivated models that capture variations in the pow
Evacuation is an important activity for reducing the number of casualties and amount of damage in disaster management. Evacuation planning is tackled as a spatial optimization problem. The decision-making process for evacuation involves high uncertainty, conflicting objectives, and spatial constraints. This study presents a Multi-Objective Artificial Bee Colony (MOABC) algorithm, modified to prov
It is only relatively recently that Post Traumatic Stress Disorder (PTSD) hasbeen recognised in children. Controlled treatment outcome studies ofchildhood PTSD are scarce, but those that exist indicate that CognitiveBehaviour Therapy (CBT) is an effective intervention. In this article, webriefly describe PTSD in children and outline some behavioural andcognitive models of the disorder. Derived fro
