Compliant Robotics in Space: A Prospective Review of Soft and Deformable Systems for Space Missions

open access: yesAdvanced Intelligent Systems, EarlyView.
Compliant robots are increasingly becoming integral to space exploration due to their adaptability, flexibility, and lightweight design. This article reviews categories such as soft, reconfigurable, and hyper‐redundant robots and their evolving role in enhancing space missions.

Portable fiber optic coupled Doppler interferometer system for detonation and shock wave diagnostics [PDF]

open access: yes, 1993
Testing and analysis of shock wave characteristics such as detonators and ground shock propagation frequently require a method of measuring velocity and displacement of the surface of interest. One method of measurement is Doppler interferometry.

Laser‐Patterned Diamond Electrodes for Adhesion and Proliferation of Human Mesenchymal Stem Cells

open access: yesAdvanced NanoBiomed Research, EarlyView.
Laser patterning is used to create diamond electrodes on insulating diamond substrates. The process yields conductive surfaces with high capacitance, wide water windows, and low impedance. The electrode‐enhancing human mesenchymal stem cell adhesion and growth are nontoxic and promote cell alignment.

Effect of oceanic turbulence on the statistical features of electromagnetic optical beam

open access: yesResults in Physics
This work deals with the intricate problem of electromagnetic optical beam propagation through oceanic turbulence. Using the extended Huygens–Fresnel principle, numerically, the behavior of the degree of cross-polarization (DOCP), electromagnetic degree ...

Quaternionic quantum interferometry [PDF]

open access: yesIn "Quantum Interferometry" ed. by F. De Martini et al., (VCH Publ., 1996) pp. 431-437, 1996
If scattering amplitudes are ordinary complex numbers (not quaternions) there is a universal algebraic relationship between the six coherent cross sections of any three scatterers (taken singly and pairwise). A violation of this relationship would indicate either that scattering amplitudes are quaternions, or that the superposition principle fails ...

Quantum interferometry with complex molecules [PDF]

open access: yesin: B. Deveaud-Pledran, A. Quattropani, P. Schwendimann (Eds.), Quantum Coherence in Solid State Systems, International School of Physics "Enrico Fermi", Course CLXXI, Vol. 171, IOS press, Amsterdam (2009), 2009
This chapter reviews recent experiments on matter wave interferometry with large molecules. Starting from an elementary introduction to matter wave physics we discuss far-field diffraction and near-field interferometry with thermally excited many-body systems.

Aberration cancellation in quantum interferometry

open access: yes, 2008
We report the first experimental demonstration of even-order aberration cancellation in quantum interferometry. The effect is a spatial counterpart of the spectral group velocity dispersion cancellation, which is associated with spectral entanglement. It
