This E-400 research studies the effects of three noise jamming techniques on the performance of a hybrid multistatic radar network in a selection of different electronic warfare (EW) situations.The performance metrics investigated are the range and velocity estimation errors found using the Cramér-Rao lower bounds (CRLBs).The hybrid multista
Chen Z, Zhang Y, Wu J, et al.Int J Chron Obstruct Pulmon Dis.2021;16:877–885.The Editor and Publisher of International Journal of Chronic Obstructive Pulmonary Disease are retracting the published article.Concerns were raised that the western blot results in Figure 4 had been duplicated with those from Figure 6 in Liu CY, Wu JH, Chen ZY, Zha
Using CHAMP magnetic field data we study the behaviour of the geomagnetic field during two mid latitude eclipses on 21 June 2001 and 22 September 2006.The possible influence of the eclipses on different ionospheric current systems, as seen in the magnetic field measured by CHAMP, is discussed.It is expected that the blocking of Fuel Injectors solar
Dual-frequency ultrasounds have demonstrated significant potential in augmenting thermal ablation efficiency for tumor treatment.Ensuring proper impedance matching between the dual-frequency transducer and the power amplifier system is imperative for equipment safety.This paper introduces a novel dual-frequency impedance matching network utilizing
This case report presents an eight-year-old girl having periauricular swelling and severe pain during mouth opening on the right-side Vases temporomandibular joint (TMJ).CBCT showed extensive destruction of the base of the skull and the roof of the glenoid fossa on the right side.The findings based on CT and MRI images with and without contrast are
