Sufficient reproduction numbers to prevent recurrent epidemics

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Current practice in the design and evaluation of control measures in disease ecology and epidemiology, including vaccination, is largely based on reproduction numbers (RNs), which represent prognostic indices of long‐term disease transmission, both in naïve populations (basic RN) and in the presence of prior exposure or infection containment ...

Contactless Cardiac Arrest Detection Using Smart Devices [PDF]

open access: yesarXiv, 2019
Out-of-hospital cardiac arrest (OHCA) is a leading cause of death worldwide. Rapid diagnosis and initiation of cardiopulmonary resuscitation (CPR) is the cornerstone of therapy for victims of cardiac arrest. Yet a significant fraction of cardiac arrest victims have no chance of survival because they experience an unwitnessed event, often in the privacy

Electro-thermal modeling of surge arrester based on adaptive power loss estimation using finite element method

open access: yes, 2016
Summary This paper proposes an adaptive model for electro-thermal analysis of metal oxide surge arresters based on finite element method. The input of the proposed model has been derived from power loss curve using adaptive network based fuzzy ...

Dietary Zinc Limitation Dictates Lifespan and Reproduction Trade‐Offs of Drosophila Mothers

open access: yesAging Cell, EarlyView.
Dietary metal ions significantly influence the lifespan and reproduction of Drosophila females. In this study, we show that not adding any of the metal ions to the diet adversely affects reproduction and lifespan. By contrast, food with no added Zn negatively impacts reproduction but not maternal lifespan, suggesting that female flies stop producing ...

Surge Arrester Monitoring under Different Operating Conditions Using Bees-ANFIS

open access: yesIranian Journal of Electrical and Electronic Engineering, 2019
The essential role of surge arresters is equipment protection against over-voltages to increase system reliability. Different monitoring techniques have been used to diagnose surge arrester condition.
