This paper assumes that considering the unknown and time-varying nature of different silicone-lube strong and weak wind field disturbances and considering the nonlinear, under-driven, strongly coupled quadrotor carrying, a load is disturbed by the complex and variable wind field and unmodeled parts when flying in the real external environment, whic
The Azure Kinect represents the latest generation of Microsoft Kinect depth cameras.Of interest in this article is the depth and spatial accuracy of the Azure Kinect and how it compares to its predecessor, the Kinect v2.In one experiment, the two sensors are used to capture a planar whiteboard at 15 locations in a grid pattern with laser scanner da
This paper introduces a robust cooperative network where an active intelligent reflecting surface (A-IRS) mounted on an unmanned aerial vehicle (UAV) is employed in order to significantly enhance the air-to-ground communications.By utilizing advanced maneuver control and intelligent reflection, the network optimizes wireless channels, substantially
Objectives: To assess the risk factors associated with Helicobacter pylori infection in the urban Chinese population.Methods: The study was conducted from March to November 2023, including 12,902 urban participants aged 18-60 years across 52 cities distributed over 26 provinces in China.Risk factors included socioeconomic status, lifestyles, and pu
Haemangioma is the most common benign tumour silicone-lube of the liver.However, an exophytic hepatic haemangioma, especially the pedunculated form, is very rare.Giant pedunculated haemangiomas are prone to complications because of the narrow size of the pedicle.A large number of lesions can potentially present as exophytic liver masses, and accura
