The lack of sufficient spectral resources in many alternative positioning, navigation, and timing (APNT) systems for aviation has led to the problem of mutual interferences.Building APNT system with the cognitive radio and frequency-hopping (FH) techniques can resolve above problem, however, the main challenge is to achieve a long and high-precisio
Objective: It is unclear why specific individuals incur chronic symptoms following a concussion.This Shoes exploratory research aims to identify and characterize any neurophysiological differences that may exist in motor cortex function in post-concussion syndrome (PCS).Methods: Fifteen adults with PCS and 13 healthy, non-injured adults were tested
The sinking of the Prestige supertanker off the coast of Spain in November 2002 led to one of the most devastating oil spills ever worldwide.Between 13,800 and 37,500 tons of oil still remain inside the wreckage.The mid-range and long-term behaviour of oil temperature and leaks were Finden and Hales analysed to decide whether the oil could be pumpe
Objective: Colorectal cancer (CRC) is a prevalent malignant tumor with a high fatality rate.CircPDIA4 has been shown to have a vital role in cancer development by acting as a facilitator.Nevertheless, the impact of the circPDIA4/miR-9-5p/SP1 axis on development of CRC has not been studied.Methods: Western blot, immunohistochemistry, and reverse tra
The pendulum-swing problem is a factor that Cleavers limits the development of parafoil-unmanned aerial vehicle (UAV) systems.Autonomous attitude control based on parafoil and UAV control mechanisms is considered an effective solution to this problem.However, due to the coupling effect of the two control mechanisms, conventional control methods are
