Coupling of Dynamical Tide and Orbital Motion

The Astrophysical Journal
The dynamical tide consists of various waves that can resonate with orbital motion. We test this coupling of the dynamical tide and orbital motion using a simple 2D shallow water model, which can be applied to a rocky planet covered with a thin ocean or ...

Neutron Resonance Spectroscopy of 117Sn from1 eV to 1.5 keV

, 1999
Parity violation has been studied recently for neutron resonances in 117Sn. The neutron resonance spectroscopy is essential for the analysis of the parity violation data. We have measured neutron resonances in 117Sn for neutron energies from 1 to 1500 eV

Candidate Members and Age Estimate of the Family of Kuiper Belt Object 2003 EL61 [PDF]

, 2007
The collisional family of Kuiper belt object (KBO) 2003 EL61 opens the possibility for many interesting new studies of processes important in the formation and evolution of the outer solar system. As the first family in the Kuiper belt, it can be studied

Strength of higher-order spin-orbit resonances [PDF]

Physical Review E, 2004
When polarized particles are accelerated in a synchrotron, the spin precession can be periodically driven by Fourier components of the electromagnetic fields through which the particles travel. This leads to resonant perturbations when the spin-precession frequency is close to a linear combination of the orbital frequencies.

Tuning the Electronic Structure and Spin State of Fe─N─C Catalysts Using an Axial Oxygen Ligand and Fe Clusters for High‐Efficiency Rechargeable Zinc–Air Batteries

Advanced Functional Materials, EarlyView.
A FeN4─O/Clu@NC‐0.1Ac catalyst containing atomically‐dispersed FeN4─O sites (medium‐spin Fe2+) and Fe clusters delivered a half‐wave potential of 0.89 V for ORR and an overpotential of 330 mV at 10 mA cm−2 for OER in 0.1 m KOH. When the catalyst was used in a rechargeable Zn–air battery, a power density of 284.5 mW cm−2 was achieved with excellent ...

15:1 RESONANCE EFFECTS ON THE ORBITAL MOTION OF ARTIFICIAL SATELLITES. DOI: 10.5028/jatm.2011.03032011

Journal of Aerospace Technology and Management, 2012
The motion of an artificial satellite is studied considering geopotential perturbations and resonances between the frequencies of the mean orbital motion and the Earth rotational motion.

Resonant Einstein-de Haas effect in a rubidium condensate

, 2007
We numerically investigate a condensate of $^{87}$Rb atoms in an F=1 hyperfine state confined in an optical dipole trap. Assuming the magnetic moments of all atoms are initially aligned along the magnetic field we observe, after the field's direction is ...

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

Advanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Dynamical mirages: How bar-induced resonant trapping can mimic substructure clustering in dynamical parameter spaces

Astronomy & Astrophysics
Context. The complex task of unraveling the assembly history of the Milky Way evolves constantly, and new substructures are identified continuously. To properly validate and characterise the family of galactic progenitors, it is important to take all the

Modeling the resonant planetary system GJ876

, 2005
The two planets about the star GJ 876 appear to have undergone extensive migration from their point of origin in the protoplanetary disk -- both because of their close proximity to the star (30 and 60 day orbital periods) and because of their occupying ...
