Anisotropic flexible stress sensors based on Loofah/CN/MWCNTs by 刘璐, 贾晓丽, 黄书童, 张景龙, 李守宝, 柯燎亮

“…Flexible stress sensors are key components for realizing intelligent perception of robots and autonomous human-machine interaction. In view of the urgent need for high-performance flexible stress sensors with high sensitivity, wide range, and short response time in the field of human-machine interaction, a flexible stress sensor with conductive anisotropy is proposed, which is made of natural porous loofah as the matrix material and carbon nanoparticles/multi-walled carbon nanotubes (CN/MWCNTs) multidimensional composite materials as conductive coatings. …”

Mortality risk associated with clinical signs of possible serious bacterial infection (PSBI) in young infants in Africa and Asia: protocol for a secondary pooled analysis by Adejumoke Idowu Ayede, Samir K Saha, Saifuddin Ahmed, Mohammad Shahidul Islam, Gary L Darmstadt, Fabian Esamai, Antoinette Tshefu Kitoto, Ebunoluwa A Adejuyigbe, Yasir Bin Nisar, Shamim Ahmad Qazi, Vaishnavi Bhamidi, Khusbu Adhikari, Ivana Marić, Robinson D Wammanda

“…We will conduct pooled, individual-level analyses of the frequency of identification of signs individually and in combinations and will conduct three types of analyses of association of signs of PSBI with mortality: (1) case fatality, which has been used in a multisite study of mortality risk associated with signs of PSBI in young infants in Africa; (2) Cox regression, which will enable time-varying analysis of exposure in relation to mortality, as has been done in a multisite study in Asia and (3) machine learning analysis, which has not previously been applied to any of the available data.Ethics and dissemination All prior studies incorporated into our pooled analysis were approved by the independent local ethics committee/institutional review board (IRB) at each study site in each country, and all study participants provided informed consent. …”
