Soliton ratchets induced by ac forces with harmonic mixing [PDF]
, 2001 The ratchet dynamics of a kink (topological soliton) of a dissipative sine-Gordon equation in the presence of ac forces with harmonic mixing (at least bi-harmonic) of zero mean is studied.

Harmonic Mean Iteratively Reweighted Least Squares for low-rank matrix recovery [PDF]
International Conference on Sampling Theory and Applications, 2017 We propose a new Iteratively Reweighted Least Squares (IRLS) algorithm for the problem of recovering a matrix X ∈ ℝd1 × d2 of rank r ≪ min(d1, d2) from incomplete linear observations, solving a sequence of quadratic problems.

Thermal energies of classical and quantum damped oscillators coupled to reservoirs [PDF]
, 2016 We consider the global thermal state of classical and quantum harmonic oscillators that interact with a reservoir. Ohmic damping of the oscillator can be exactly treated with a 1D scalar field reservoir, whereas general non-Ohmic damping is conveniently ...

Weakly convex biharmonic hypersurfaces in nonpositive curvature space forms are minimal
, 2013 A submanifold $M^m$ of a Euclidean space $R^{m+p}$ is said to have harmonic mean curvature vector field if $\Delta \vec{H}=0$, where $\vec{H}$ is the mean curvature vector field of $M\hookrightarrow R^{m+p}$ and $\Delta$ is the rough Laplacian on $M ...

Experimental Demonstration of Squeezed State Quantum Averaging [PDF]
, 2010 We propose and experimentally demonstrate a universal quantum averaging process implementing the harmonic mean of quadrature variances. The harmonic mean protocol can be used to efficiently stabilize a set of fragile squeezed light sources with ...

Integration with an adaptive harmonic mean algorithm [PDF]
International Journal of Modern Physics A, 2018 Numerically estimating the integral of functions in high dimensional spaces is a nontrivial task. A oft-encountered example is the calculation of the marginal likelihood in Bayesian inference, in a context where a sampling algorithm such as a Markov ...

Dynamics analysis of dengue fever model with harmonic mean type under fractal-fractional derivative
AIMS MathematicsDengue is a viral illness transmitted by Aedes mosquitoes and is a significant global threat. In this study, we developed a model of the dengue epidemic that incorporates larvicide and adulticide, as well as the harmonic mean incidence rate under fractal-
