Oscillation criteria for linear difference equations with several variable delays [PDF]
Opuscula Mathematica, 2021 We obtain new sufficient criteria for the oscillation of all solutions of linear delay difference equations with several (variable) finite delays. Our results relax numerous well-known limes inferior-type oscillation criteria from the literature by ...

Constants of Motion of the Harmonic Oscillator [PDF]
Mathematical Physics, Analysis and Geometry, 2020 We prove that Weyl quantization preserves constant of motion of the Harmonic Oscillator. We also prove that if $f$ is a classical constant of motion and $\mathfrak{Op}(f)$ is the corresponding operator, then $\mathfrak{Op}(f)$ maps the Schwartz class into itself and it defines an essentially selfadjoint operator on $L^2(\mathbb R^n)$. As a consequence,

Relativistic oscillator of constant period [PDF]
Physical Review A, 1996 A relativistic oscillator whose period is independent of its energy is of great fundamental importance in both relativistic classical mechanics and relativistic quantum mechanics. In this work theoretical and computational investigations of such a constant period oscillator are reported, with emphasis on basic mathematical and physical properties of ...

Numerical Investigation of Flow Characteristics in a Centrifugal Pump Impeller with Sinusoidal Flow Rates of Different Oscillation Amplitudes [PDF]
Journal of Applied Fluid Mechanics, 2022 This study describes the large eddy simulations of a centrifugal pump impeller considering a sinusoidal flow rate and a constant rotation speed. Five different oscillation amplitudes of flow rate (A = 0.1Qd, 0.15Qd, 0.2Qd, 0.25Qd, and 0.3Qd, Qd indicates

MSLED, neutrino oscillations and the cosmological constant [PDF]
Journal of High Energy Physics, 2005 We explore the implications for neutrino masses and mixings within the minimal version of the supersymmetric large-extra-dimensions scenario (MSLED). This model was proposed in {\tt hep-ph/0404135} to extract the phenomenological implications of the promising recent attempt (in {\tt hep-th/0304256}) to address the cosmological constant problem ...

Fast Apparent Oscillations of Fundamental Constants
Annalen der Physik, 2020 AbstractPrecision spectroscopy of atoms and molecules allows one to search for and to put stringent limits on the variation of fundamental constants. These experiments are typically interpreted in terms of variations of the fine structure constant α and the electron‐to‐proton mass ratio .

Frictional behavior of quartz gouge during slide-hold-slide considering normal stress oscillation
International Journal of Coal Science & Technology, 2023 Slide-hold-slide (SHS) test is an essential experimental approach for studying the frictional stability of faults. The origin SHS framework was established based on a consistent constant normal stress, which cannot truly reflect the stress disturbance ...

Observation of Landau Level-Dependent Aharonov-Bohm-Like Oscillations in a Topological Insulator
Nanoscale Research Letters, 2020 We study the quantum oscillations in the BiSbTe3 topological insulator. In addition to the Shubnikov-de Haas (SdH) oscillation, the Aharonov-Bohm-like (ABL) oscillations are also observed.

Oscillation and non-oscillation criterion for Riemann–Weber type half-linear differential equations
Electronic Journal of Qualitative Theory of Differential Equations, 2016 By the combination of the modified half-linear Prüfer method and the Riccati technique, we study oscillatory properties of half-linear differential equations.
