In recent years several new potentials obtained from the supersymmetric formalism have been applied to quantum mechanics @1,2#. These potentials were derived from shape invariant potentials, and their mathematical and formal aspects have been discussed @3#. However, they have not been applied to any real physical system. In this work, we propose a problem where a harmonic oscillator isospectral...

Free-piston engine linear generators (FPELGs) are an innovative power device that exhibits the distinctive dynamics of pistons and performance free-piston engines. Furthermore, single-cylinder/single-piston FPELG structure type has more advantages than other types, including a straightforward ease control. However, when coupled with various rebound devices, operational characteristics piston FP...

We present the design, fabrication and test of a large-displacement electromagnetic actuator using the meander springs, exposed partially to magnetic field. We compare two prototypes including the conventional prototype F with the meander springs exposed fully to magnetic field and the present prototype P with the meander springs exposed partially to magnetic field. In the experimental study, t...

Terrestrial sulfidic springs support diverse microbial communities by serving as stable conduits for geochemically diverse and nutrient-rich subsurface waters. Microorganisms that colonize terrestrial springs likely originate from groundwater, but may also be sourced from the surface. As such, the biogeographic distribution of microbial communities inhabiting sulfidic springs should be controll...
