Conceptual designs of multi-degree of freedom compliant parallel manipulators composed of wire-beam based compliant mechanisms [PDF]
, 2014 This paper proposes conceptual designs of multi-degree(s) of freedom (DOF) compliant parallel manipulators (CPMs) including 3-DOF translational CPMs and 6-DOF CPMs using a building block based pseudo-rigid-body-model (PRBM) approach.

Programmable Activation of Quantum Emitters in High‐Purity Silicon with Focused Carbon Ion Beams
Advanced Quantum Technologies, Volume 8, Issue 1, January 2025.Here, a carbon source for focused ion beams is developed and utilized for the simultaneous creation of two types of quantum emitters in silicon, the W and G centers. Furthermore, a multi‐step implantation protocol is applied for the programmable activation of the G centers with a spatial resolution better than 250 nm. This approach provides a route for

Stability margins and model-free control: A first look [PDF]
, 2014 We show that the open-loop transfer functions and the stability margins may be defined within the recent model-free control setting. Several convincing computer experiments are presented including one which studies the robustness with respect to delays ...

Free ultra-high-Q microtoroid: a tool for designing photonic devices [PDF]
, 2007 We describe techniques that enable fabrication of a new class of photonic devices based on free UH-Q microresonators. Preliminary results show that free silica microtoroids with Qs above 30 million can be fabricated and transferred to different platforms

Journal of Synchrotron Radiation, Volume 32, Issue 1, Page 217-224, January 2025.X‐ray ensemble diffraction microscopy (XEDM) is an approach to enhance the signal‐to‐noise ratio in high‐frequency regions of scattering. This article presents direct imaging of 55 nm core–shell silica–gold nanoparticles at a 6.8 nm resolution and 19 nm nodavirus‐like‐particles in solution at a 2.6 nm resolution to demonstrate the high spatial ...
