Item response mechanics

open access: yes, 2021
Statistical models for the relations between variables encompass assumptions about the underlying mechanism that generated the relations in the observed data. This dissertation introduces item response mechanics as the study of data-generating mechanisms underlying an item response, and their implementation in psychometric process-measurement models.

A 3D Discrete-Continuum Coupling Approach for Investigating the Deformation and Failure Mechanism of Tunnels across an Active Fault: A Case Study of Xianglushan Tunnel

open access: yesApplied Sciences, 2019
For water transmission tunnels constructed in high-risk seismic regions of western China, active faults pose threats of serious ruptures to the tunnels. To overcome this issue, a 3D discrete-continuum coupling approach is introduced into the study.

Atom-mirror cooling and entanglement using cavity Electromagnetically Induced Transparency

open access: yes, 2011
We investigate a hybrid optomechanical system comprised of a mechanical oscillator and an atomic 3-level ensemble within an optical cavity. We show that a suitably tailored cavity field response via Electromagnetically Induced Transparency (EIT) in the ...

Nanorheology of viscoelastic shells: Applications to viral capsids

open access: yes, 2007
We study the microrheology of nanoparticle shells [Dinsmore et al. Science 298, 1006 (2002)] and viral capsids [Ivanovska et al. PNAS 101, 7600 (2004)] by computing the mechanical response function and thermal fluctuation spectrum of a viscoelastic ...

Thermal-mechanical response to simple shear extension [PDF]

open access: yes
The mechanism of extension in the continental crust is apparently much more complex than that acting in the oceanic lithosphere. Recently, Wernicke has proposed that a significant fraction of extension in the continental lithosphere may occur by a simple
