Weexplore the effect of the externalmagnetic andAharonov–Bohm (AB) flux fields on the energy levels of Dirac particle subjects to mixed scalar and vector anharmonic oscillator field in the twodimensional (2D) space. We calculate the exact energy eigenvalues and the correspondingun-normalized two-spinor-components wave functions in terms of the chemical potential parameter, magnetic field streng...

Agricultural production affects environmental and human health. Many consequences are borne involuntarily rather than chosen because no formal market trading takes place for ecosystem functions or health attributes. These impacts, or externalities, may be quantified indirectly by assigning dollar values through a process called valuation, which informs agricultural production and policy decisio...

This descriptive cross sectional census study identified the perceptions of Extension and Outreach employees of Iowa State University in the United States about job autonomy and control after two years of a major restructuring. Employees perceived autonomy and control over expressing views and ideas about their work and spending time on the job but perceived little influence over budget allocat...

The states of penile erection have not been quantified to establish their relationship to intracorporal fluid pressure and to soft tissue constraint. Computer-based circumferential rigidity sensing during erectile cycles now permits circumferential size and rigidity characterization. Measurements during dynamic infusion cavernometry and cavernosography relate intracorporal pressure and axial ri...

Mental states-such as thinking, remembering, or feeling angry, happy, or dizzy-have a clear internal component. We feel a certain way when we are in these states. These internal experiences may be simulated when people understand conceptual references to mental states. However, mental states can also be described from an "external" perspective, for example when referring to "smiling." In those ...

Using Hartree-Fock Su-Sheriffer-Heeger (HF-SSH) model, we have studied the dependence of the energies of the ground (magnetic triplet state) and the first exited (nonmagnetic singlet state) states of the size-2 trigonal zigzag graphene nanoflake (size-2 NF) on the intensity of an external in plane static electric field at zero temperature. We identify a transition from the magnetic triplet stat...

In this paper, a novel approach for finite-time stabilization of uncertain affine systems is proposed. In the proposed approach, a fast terminal sliding mode (FTSM) controller is designed, based on the input-output feedback linearization of the nonlinear system with considering its internal dynamics. One of the main advantages of the proposed approach is that only the outputs and external state...
