The pendulum-swing problem is a factor that 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 Oil seru
Using prestressed anchor cables is one of the most common approaches for reinforcing slopes.By establishing a calculation model for a high and steep slope, the changes of displacement of slope foot and increment of force on the cables under different prestresses were calculated.Furthermore, the influence of prestress on the changes of displacement
Conducting polymer 3D microelectrodes have been fabricated for possible future neurological applications.A combination of micro-fabrication techniques and chemical polymerization methods has been used to create pillar electrodes in polyaniline and polypyrrole.The thin polymer films obtained showed Needles uniformity and good adhesion to both horizo
Abstract Background Echinococcosis is a zoonotic disease caused by the larval stages of taeniid cestodes of the genus Echinococcus.The two major types of infection in humans are cystic echinococcosis (CE) or hydatidosis and alveolar echinococcosis (AE).It is endemic in some parts of the world, such as the Middle East, with Iran being a part of it.T
BackgroundMalignancies, especially lymphoma, are a common cause of adult secondary HLH and an independent risk factor for the prognosis of HLH patients.MethodsPatients with lymphoma alone or concurrent lymphoma-associated phagocytic syndrome (LAHS) admitted to Beijing Friendship Hospital from January 2016 to December 2020 were enrolled in this stud
