Recently, methods based on deep learning have been applied to target detection using synthetic aperture radar (SAR) images.However, due to the SAR imaging mechanism and low signal-clutter-noise-ratio (SCNR), it is still a challenging task to perform aircraft detection using SAR imagery.To address this issue, a novel aircraft detection method is pro
When shield machine traverses through hard rock mass, disc cutters will be abraded to different degrees.Excessive height difference exists between adjacent disc cutters, which critically affects the rock-breaking efficiency.Relying on a shield section of hard rock mass in Qingdao, the disc cutter abrasions are measured on site, and the reason for l
Background and purpose: Men and women show different reactions to trauma and that is believed to be the reason behind the higher prevalence of post-traumatic stress disorder (PTSD) in women.Cholinergic signaling has long been known to be involved tillman 750m in the processing of fear-related information and the amygdala is a critical center for fe
Several COVID-19 vaccines have been developed and approved for use around the world from December 2020, to combat the pandemic caused by the novel SARS-CoV-2 virus.Several ophthalmic manifestations of the COVID-19 vaccines have been reported by ophthalmologists.This review was undertaken read more to recognize, encourage active reporting and determ
Harvesting has received most theoretical, empirical, and policy attention towards understanding common-pool resource dilemmas.Yet, pre-harvesting and post-harvesting activities influence harvesting outcomes as well.Broadening the analytical focus beyond harvesting is needed to imagine new ways here of theorizing and governing the commons.Fishing-wh
