The inverted harmonic oscillator problem is investigated quantum mechanically. The exact wave function for the confined inverted oscillator is obtained and it is shown that the associated energy eigenvalues are discrete and it is given as a linear function of the quantum number $n$.

Multidecadal climate oscillations during the past millennium driven by volcanic forcing
A volcanic source of variation The Atlantic Multidecadal Oscillation (AMO), a 50- to 70-year quasiperiodic variation of climate centered in the North Atlantic region, was long thought to be an internal oscillation of the climate system. Mann et al.

Frequency versus relaxation oscillations in a semiconductor laser with coherent filtered optical feedback [PDF]
We investigate the dynamics of a semiconductor laser subject to coherent delayed filtered optical feedback. A systematic bifurcation analysis reveals that this system supports two fundamentally different types of oscillations, namely relaxation ...

Oscillators and Oscillations in the Basal Ganglia [PDF]
What is the meaning of an action potential? There must be different answers for neurons that fire spontaneously, even in the absence of synaptic input, and those driven to fire from a resting membrane potential. In spontaneously firing neurons, the occurrence of the next action potential is guaranteed; only variations in its timing can carry the ...

Neural Oscillations in Aversively Motivated Behavior
Fear and anxiety-based disorders are highly debilitating and among the most prevalent psychiatric disorders. These disorders are associated with abnormal network oscillations in the brain, yet a comprehensive understanding of the role of network ...

Finite oscillator models: the Hahn oscillator [PDF]
A new model for the finite one-dimensional harmonic oscillator is proposed based upon the algebra u(2)_ . This algebra is a deformation of the Lie algebra u(2) extended by a parity operator, with deformation parameter . A class of irreducible unitary representations of u(2)_ is constructed.

Conductance oscillations of a spin-orbit stripe with polarized contacts [PDF]
We investigate the linear conductance of a stripe of spin-orbit interaction in a 2D electron gas; that is, a 2D region of length $\ell$ along the transport direction and infinite in the transverse one in which a spin-orbit interaction of Rashba type is ...

Feature Detection in Visual Cortex during Different Functional States
Cortical activity exhibits distinct characteristics in different functional states. In awake behaving animals it shows less synchrony, while in rest or sleeping state cortical activity is most synchronous.

Exponentially fitted block backward differentiation formulas for pricing options
A family of Exponentially Fitted Block Backward Differentiation Formulas (EFBBDFs) whose coefficients depend on a parameter and step-size is developed and implemented on the Black–Scholes partial differential equation (PDE) for the valuation of options ...
