Low-Earth orbit (LEO) satellite communication is poised to be a key enabler in the burgeoning 6G era. However, emergence of unauthorized LEO user terminals (LSUTs) poses significant threats security, creating an urgent need for effective LSUT surveillance. Nevertheless, surveillance challenging since transmit beamforming leads highly directional uplink beam, which complicates reception high signal-to-noise ratio (SNR) signals necessary accurate geolocation and monitoring by equipment. To...
This paper investigates the issue of searching and geolocating a radio frequency (RF) emitter with an unmanned aerial vehicle (UAV) in rich scattering environment. The absence knowledge characteristics target RF signals, ground-to-air channels, potential geographical distribution makes efficient trajectory planning (TP) intractable. Since average signal-to-noise ratio (SNR) signal captured by UAV changes across search area, state-of-the-art TP is inapplicable due to assumption single problem...
Abstract Background Currently, conventional placement of natural pressure drainage after single-level anterior cervical discectomy with fusion and plating (ACDF) is used clinically to prevent complications such as symptomatic epidural hematoma incision infection. Nevertheless, a literature review reported that there no uniform standard for whether place ACDF surgery, comparative studies on this subject are rare.Methods A prospective study 100 patients who underwent from January 2017 June...
Objective: To investigate the short-term effect of Isobar dynamic stabilization system fixation combined with lumbar discectomy in patients disc herniation. Methods: From June 2015 to 2017, 62 herniation treated First Affiliated Hospital Zhengzhou University were divided into control group and observation according therapy. The 31 simple excision nucleus pulposus discectomy. score Oswestry disability index (ODI) Japanese Orthopedic Association (JOA) low back pain, adjacent stage activity,...
Objective To explore the clinical efficacy of secondary posterior internal fixation after transoral anterior atlantoaxial release under 3D operative microscopy for treatment irreducible dislocation. Methods From January 2014 to May 2016, 12 patients with dislocation were treated in our hospital. They 7 males and 5 females, an average age 37.1 years (from 25 54 years). The was analyzed terms their visual analogue scale (VAS), Japanese Orthopaedic Association (JOA) scoring, improvement...
