The invasion of Apis florea in Taiwan was first recorded in 2017.The deformed wing virus (DWV) has been identified as a common bee virus in apiculture around the world.Ectoparasitic mites are the main DWV vector for horizontal transmission.However, there are few studies about the ectoparasitic mite of Euvarroa sinhai, which has been found in A.flor
Expedited Design Closure of Antenna Input Characteristics by Trust Region Gradient Search and Principal Component Analysis
Optimization-based parameter tuning has become an inherent part of contemporary antenna design process.For the sake of reliability, it is typically conducted at the level of full-wave electromagnetic (EM) simulation models.This may incur considerable computational expenses depending on the cost of an individual EM analysis, the number of adjustable
Hydro-mechanical coupling of granite with micro-defects: Insights into underground energy storage
In order to revel hobbit door for sale the hydro-mechanical coupling characteristics of granite at various pore pressures and confining pressures.The spatial micro-pore structure before and after the failure of granite is extracted by high-precision CT scanning system.The results show that the UCS of the damaged granite decreases with the increase
