Theoretical model of droplets motions on solid surface with radial wettable and evaporation rate gradients

Wettability gradient in radial direction and evaporation rate gradient can cause droplet motion on a solid surface. Here a theoretical model is proposed. Besides, an equation of droplet velocity is derived on a solid surface. We consider the wettability and evaporation rate gradients are mainly caused by the chemical composition and surface roughness, only along the radial direction. Surface tensi

Investigation of bubble departure radius in subcooled pool boiling under microgravity condition

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

Depression and parental stress among Swedish fathers in the postnatal period: Screening and working through help-seeking barriers

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

Spectral design of signal-adapted tight frames on graphs

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

Defending Paper Gods : Aleister Crowley and the Reception of Daoism in Early Twentieth Century Esotericism

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

Evolution of organ systems in the Crustacea: Mystacocarida and Cephalocrida in retrospect

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

Stand-Alone Artificial Intelligence for Breast Cancer Detection in Mammography : Comparison With 101 Radiologists

BACKGROUND: Artificial intelligence (AI) systems performing at radiologist-like levels in the evaluation of digital mammography (DM) would improve breast cancer screening accuracy and efficiency. We aimed to compare the stand-alone performance of an AI system to that of radiologists in detecting breast cancer in DM.METHODS: Nine multi-reader, multi-case study datasets previously used for different

Channel Correlation Diversity in MU-MIMO Systems - Analysis and Measurements

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
