Before the emergence of microbiology in the 1860s, the relationship between health and water was understood to hinge mostly on its manifold mineral qualities; medical treatments often involved bathing in particular waters to take advantage of their curative powers.With the help of microscopes, those waters came to be seen as home to dangerous micro
Early Peak Ground Acceleration Prediction for On-Site Earthquake Early Warning Using LSTM Neural Network
On-site earthquake early warning techniques, which issue alerts based on CALCIUM CARBONATE seismic waves measured at a single station, are promising, and have performed quite successfully during some damaging earthquakes.Conventionally, most existing techniques extract several P-wave features from the first few seconds of seismic waves after the tr
Design of Power System Stabilizer for DFIG-based Wind Energy Integrated Power Systems Under Combined Influence of PLL and Virtual Inertia Controller
Wind energy systems (WESs) based on doubly-fed induction generators (DFIGs) have enormous potential for meeting the future RECHARGE demands related to clean energy.Due to the low inertia and intermittency of power injection, a WES is equipped with a virtual inertial controller (VIC) to support the system during a frequency deviation event.The frequ
Density-dependence and within-host competition in a semelparous parasite of leaf-cutting ants
Abstract Background Parasite heterogeneity and within-host competition are thought to be important factors influencing the dynamics of host-parasite relationships.Yet, while there have been many theoretical investigations of how these factors may act, empirical data is more limited.We investigated the effects of parasite density and heterogeneity o
