The paper considers the class of Hamiltonian systems with two degrees of freedom.Based on the classical normal form, according to the rules of Born-Jordan and Weyl-MacCoy, its quantum analogs are constructed for which the eigenvalue problem is solved and approximate formulas for the energy spectrum are found.For particular values of the parameters
Objective: The objective of this study was to investigate a large outbreak of shigellosis in Papua New Guinea that began in a camp for internally displaced persons before spreading throughout the general community.Methods: Outbreak mitigation strategies were implemented in the affected area to curtail the spread of the disease.Data were collected f
An overview on high-resolution and fast interrogation of optical-fiber sensors relying on laser reflection spectroscopy is given.Fiber Bragg-gratings (FBGs) and FBG resonators Stove Knob Clip built in fibers of different types are used for strain, temperature and acceleration measurements using heterodyne-detection and optical frequency-locking tec
