This article investigates an event-trigger-based fixed-time adaptive tracking control problem for strict feedback nonlinear systems with external disturbances.Relying on the Foot Stools values of the control input and tracking error, the relative fixed event-triggered control scheme is introduced to save communication resources on the basis of ensu
A semipositone fourth-order two-point boundary value problem is considered.In mechanics, the problem describes the deflection of an elastic beam rigidly fastened Screws on the left and simply supported on the right.Under some conditions concerning the first eigenvalue corresponding to the relevant linear operator, the existence of nontrivial soluti
The essay analyses the evolution of the national and Circular rugs international scene between the Twentieth and the Twenty-first century to reach our days, plagued by the pandemic from Covid-19 and the war in Ukraine.The Author dwells on the need to rebuild a ASHWAGANDHA new multilateral architecture at the international level to effectively addre
Hepatitis C virus (HCV) is a serious and growing public health problem despite recent developments of antiviral therapeutics.To achieve global elimination of HCV, an effective cross-genotype vaccine is needed.The failure of previous vaccination trials to elicit an effective cross-reactive immune response demands better vaccine antigens to induce a
BackgroundNeurocysticercosis (NCC), and cystic echinococcosis (CE) are two neglected diseases caused by cestodes, co-endemic in many areas of the world.Imaging studies and serological tests are used in the diagnosis of both parasitic diseases, but cross-reactions may confound the results of the latter.The novel multiplex bead-based assay with recom
