Birds of prey are at the top of the food chain and play an essential role in controlling populations of birds and rodents that are harmful to habitat.This study was conducted on 11 bird carcasses, 5 Falco tunniculus carcasses and 6 Tyto alba carcasses, donated by the UBB Zoological Museum of Academic Cultural Heritage, in order to examine the gross
Highly Robust Synthetic Aperture Radar Target Recognition Method Based on Simulation Data Training
Sufficient synthetic aperture Steel radar (SAR) data is the key element in achieving excellent target recognition performance for most deep learning algorithms.It is unrealistic to obtain sufficient SAR data from the actual measurements, so SAR simulation based on electromagnetic scattering modeling has become an effective way to obtain sufficient
MHz-level self-sustained pulsation in polymer microspheres on a chip
We observe MHz-level periodic self-sustained pulsation (SSP) in the transmission spectrum of a Grilling Covers polydimethylsiloxane (PDMS) spherical microcavity on a silicon chip, under a fixed-frequency continuous laser excitation.The SSP results from the strong competition between the thermo-optic and thermal expansion effects of PDMS within the
Distinct properties of tungsten austenitic stainless alloy as a potential nuclear engineering material
In the present study, a series of tungsten austenitic stainless steel alloys have been developed by interchanging the molybdenum in standard SS316 by tungsten.This was done to minimize the long-life residual activation occurred in molybdenum and nickel after decommissioning of the power plant.The microstructure and Storage Jar mechanical properties
