Journal of Approximation Theory, 2003 Using a theorem of \textit{S. J. Gardiner} [Harmonic approximation (1995; Zbl 0826.31002)], the author shows that there exists a harmonic function \(h\) on a non-empty open subset \(\Omega\) of \(\mathbb{R}^d\), where \(d\geq 2\), which behaves wildly near every boundary point of \(\Omega\).

Harmonic Causation and Harmonic Echoes [PDF]
Nature, 1873 IN reference to the question of “Harmonic Echoes,” allow me to suggest to those who may have the opportunity of observation, how desirable it is that these echo-tones should be investigated in a manner to determine whether they are truly harmonic or not. There would be no difficulty in testing the sounds given in response to the notes of a closed organ-

Advanced Functional Materials, EarlyView.This work explores Li‐substituted P2 layered oxides for Na‐ion batteries by crystallographic and electrochemical studies. The effect of lithium on superstructure orderings, on phase transitions during synthesis and electrochemical cycling and on the interplay of O‐ versus TM‐redox is revealed via various advanced techniques, including semi‐simultaneous

Archives of Acoustics, 2013 In this study we investigate the appearance of combination tones in violins. Most authors in recent times have emphasised that combination tones occur inside the ear exclusively (intra-aural).

Monopole Vector Spherical Harmonics
, 1993 Eigenfunctions of total angular momentum for a charged vector field interacting with a magnetic monopole are constructed and their properties studied. In general, these eigenfunctions can be obtained by applying vector operators to the monopole spherical

Non-sinusoidal current and current reversals in a gating ratchet [PDF]
, 2015 In this work, the ratchet dynamics of Brownian particles driven by an external sinusoidal (harmonic) force is investigated. The gating ratchet effect is observed when another harmonic is used to modulate the spatially symmetric potential in which the ...

Lorentz Harmonics, Squeeze Harmonics and Their Physical Applications [PDF]
Symmetry, 2011 Among the symmetries in physics, the rotation symmetry is most familiar to us. It is known that the spherical harmonics serve useful purposes when the world is rotated. Squeeze transformations are also becoming more prominent in physics, particularly in optical sciences and in high-energy physics.

Advanced Functional Materials, EarlyView.This study investigates H4TBAPy‐based metal–organic frameworks (MOFs) ‐ NU‐1000, NU‐901, SrTBAPy, and BaTBAPy ‐ for multiphoton absorption (MPA) performance. It observes topology‐dependent variations in the 2PA cross‐section, with BaTBAPy exhibiting the highest activity.

, 2001 The generation of harmonics of the voltage response is considered when an AC current is applied through a superconducting film above T_c. It is shown that almost at all temperatures the mechanism of the temperature oscillations created by the AC current ...

Generation of five phase-locked harmonics by implementing a divide-by-three optical frequency divider [PDF]
, 2015 We report the generation of five phase-locked harmonics, f1:2403 nm, f2:1201 nm, f:801 nm, f4:600 nm, and f5:480 nm with an exact frequency ratio of 1:2:3:4:5 by implementing a divide-by-three optical frequency divider in the high harmonic ...
