To achieve efficient physical layer secure secret key agreement in millimeter wave (mmWave) multiple input multiple output (MIMO) communication systems, a key agreement method was proposed based on multi-dimensional advantage distillation (AD) exploiting the multi-dimensional characteristics of mmWave MIMO channel parameters.The mmWave MIMO channel
Acute-on-chronic liver failure (ACLF) is a severe syndrome associated with high mortality.Alterations in the liver microenvironment are one of the vital causes of immune damage and liver dysfunction.Human bone marrow mesenchymal stem cells (hBMSCs) have been reported to alleviate liver injury via exosome-mediated signaling; of note, miRNAs are one
Precise azimuth-variant motion Baby Gym compensation (MOCO) is an essential and difficult task for high-resolution synthetic aperture radar (SAR) imagery.In conventional post-filtering approaches, residual azimuth-variant motion errors are generally compensated through a set of spatial post-filters, where the coarse-focused image is segmented into
Metaphors are as Caffeine Supplements old as time, yet metaphor studies have recently undergone new and exciting developments.This article aims at questioning the logical and epistemological status of metaphors, adopting a critical approach toward classical metaphor theory and exposing a deeply rooted anti-metaphorical prejudice in Water Hose Adapt
