Theory of Electron Transport in Two-Barrier Five-Layer Semiconductor Structures
East European Journal of PhysicsThe dependence of the transparency coefficient of a five-layer two-barrier structure on the electron energy and the ratio of the widths of two neighboring potential barriers is calculated.

Particle tunneling and scattering in a three-dimensional potential with a hard core and an external potential barrier [PDF]
Ядерна фізика та енергетика, 2009 The non-relativistic particle tunneling and scattering through a spherical three-dimensional potential barrier (either rectangular, or Coulomb repulsion), containing a spherical potential rectangular well with a hard core inside, had been studied.

On nontrivial solutions of nonlinear Schrödinger equations with sign-changing potential
Advances in Difference Equations, 2021 In this paper, we consider the superlinear Schrödinger equation with bounded potential well. The potential here is allowed to be sign-changing. Without assuming the Ambrosetti–Rabinowitz-type condition, we prove the existence of a nontrivial solution and

Communication and Language Profiles of Children Treated for Posterior Fossa Brain Tumors
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Cognitive and language deficits are frequently reported sequelae of posterior fossa brain tumors (PFBT). Typically, delayed onset impedes prompt assessment and early intervention. This has devastating implications for quality of life.

Energy distribution of the "shake off" electrons of the atomic shell at internal conversion [PDF]
Ядерна фізика та енергетика, 2009 Researches of the energy spectrum of electrons of "shake off" are conducted at internal conversion of transition 122 keV E2 in the decay of 152Eu. The measurements are executed in the range of 200 - 1000 eV on the installation of coincidences of γ-quanta

Kink localization under asymmetric double-well potentials [PDF]
Physical Review E, 2012 We study diffuse phase interfaces under asymmetric double-well potential energies with degenerate minima and demonstrate that the limiting sharp profile, for small interface energy cost, on a finite space interval is in general not symmetric and its position depends exclusively on the second derivatives of the potential energy at the two minima (phases)

On the universality of potential well dynamics [PDF]
, 2017 Given a smooth potential function $V : \mathbf{R}^m \to \mathbf{R}$, one can consider the ODE $\partial_t^2 u = -(\nabla V)(u)$ describing the trajectory of a particle $t \mapsto u(t)$ in the potential well $V$.

Coherence resonance in an excitable potential well [PDF]
Physics Letters, 2018 The excitable behaviour is considered as motion of a particle in a potential field in the presence of dissipation. The dynamics of the oscillator proposed in the present paper corresponds to the excitable behaviour in a potential well under condition of ...
