BackgroundChagas is a complex and multidimensional socio-environmental health phenomenon, in which different components converge and interact.Historically, this disease was associated with insect vectors found in the rural environment.However, in the Americas, we are currently facing a new paradigm, in which different scenarios soderhamn ottoman co
Space laser optical communication has been widely investigated to achieve high bit rate information transmission.To enhance the information transmission security in space laser optical communication, chaos-based encryption scheme is adopted.It involves many parameters in designing a space soderhamn ottoman cover chaotic optical communication system
A novel acoustic metamaterial structure, made up of both resonator and multiple channels, is proposed to insulate low-frequency broadband noises.Three bandgaps with a total width of 658 Hz can be obtained below 900 Hz when the structure appears as a single negative characteristic within specific frequency ranges.These bandgaps are caused by the sta
Aiming at the accidents acupatch of high-voltage electrical equipment in electric locomotive such as burn out of resistance-capacity absorption device, explosion damage of arrester, DC over-voltage of converter led by overhead line resonant overvoltage happening with increasing frequency in Huaihua railway hub area since 2018, through theoretical a
The traditional calibration objective of hydrological models is to optimize streamflow simulations.To identify the value of satellite soil moisture data in calibrating hydrological models, a new objective of optimizing soil moisture simulations has been added to bring in satellite data.However, it leads to problems: (i) how to consider the trade-of
