Mesodynamics with implicit degrees of freedom [PDF]
The Journal of Chemical Physics, 2014 Mesoscale phenomena—involving a level of description between the finest atomistic scale and the macroscopic continuum—can be studied by a variation on the usual atomistic-level molecular dynamics (MD) simulation technique. In mesodynamics, the mass points, rather than being atoms, are mesoscopic in size, for instance, representing the centers of mass ...

Nanomechanical topological insulators with an auxiliary orbital degree of freedom [PDF]
Nature Nanotechnology, 2020 Discrete degrees of freedom, such as spin and orbital, provide a tool to manipulate electrons, photons and phonons. Topological insulators have stimulated intense interests in condensed-matter physics, optics, acoustics and mechanics, usually with a ...

Degree of Freedom of Gene Expression in Saccharomyces cerevisiae
Microbiology Spectrum, 2022 The complexity of genome-wide gene expression has not yet been adequately addressed due to a lack of comprehensive statistical analyses. In the present study, we introduce degree of freedom (DOF) as a summary statistic for evaluating gene expression ...

Two-Degree-of-Freedom Controller Tuning
Mendel, 2018 Two-degree-of-freedom controllers have the ability to affect the dynamics of a system when the reference value changes. The answer to the question of parameter tuning for this additional lter still remains unclear we describe a new method for the design ...

On the “degrees of freedom” of the lasso
The Annals of Statistics, 2007 We study the effective degrees of freedom of the lasso in the framework of Stein's unbiased risk estimation (SURE). We show that the number of nonzero coefficients is an unbiased estimate for the degrees of freedom of the lasso--a conclusion that requires no special assumption on the predictors.

Deep reinforcement learning for six degree-of-freedom planetary landing
Advances in Space Research, 2020 This work develops a deep reinforcement learning based approach for Six Degree-of-Freedom (DOF) planetary powered descent and landing. Future Mars missions will require advanced guidance, navigation, and control algorithms for the powered descent phase ...

A single degree of freedom model for cracked beam
Vietnam Journal of Mechanics, 2023 This paper presents a simplified model of cracked beam by single-degree-of-freedom system. Equivalence between the beam and SDOF models means that they have the same fundamental natural frequency and similar frequency response functions (FRFs ...

2 Degree-of-Freedom Spiral Micromirror Manipulator
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2008 We present a process for the fabrication and assembly of a novel spiral-shaped micromirror manipulator for free space optical switching. The manipulator is comprised of two different parts, which are fabricated using conventional surface micromachining ...
