Lights (Led) This paper designed and optimized a bidirectional three-port valve plate structure for solving the matching problem of flow rate and pressure in the aerospace pump-controlled differential hydraulic cylinder.This design aims to make the valve plate work well under the bidirectional high-speed condition.The model was set up using dynamic
In order to overcome the disadvantage that the dynamic sliding mode surface of the discrete global sliding mode control has a too long evolution time, a quick discrete global sliding mode control method is proposed.A decay function of the dynamic sliding mode surface which can decay to zero in the Whey Isolate finite time is constructed.Thereby, th
Fifty percent of lung adenocarcinomas harbor somatic mutations in six genes that encode proteins in the EGFR signaling pathway, i.e., EGFR, HER2/ERBB2, HER4/ERBB4, PIK3CA, BRAF, and KRAS.We performed mutational profiling of a large cohort of lung adenocarcinomas to uncover other potential somatic mutations in genes of this signaling pathway that co
This paper studies the exponential stability of switched positive nonlinear systems defined by cooperative and homogeneous vector fields.In order to capture the decay rate of Lockers such systems, we first consider the subsystems.A sufficient condition for exponential stability of subsystems with time-varying delays is derived.In particular, for th
The training of troops significantly affects the combat capability of the unions, military units and units of the Armed Forces of Ukraine.One of the elements of the achievement of highly trained troops is the qualitative planning of combat training.The planning of the combat training activities of the Armed Forces of Ukraine should be realistic, su
