Red‐Sensitive Photopolymerizable Glass for Fabrication of Holographic Optical Elements

open access: yesAdvanced Optical Materials, EarlyView.
This study presents a novel photopolymerizable glass capable of optical patterning using red‐wavelength laser exposure. Red‐light sensitivity was achieved through the incorporation of a photoinitiating system composed of methylene blue (MB) and N‐phenylglycine (NPG).

Mechanism of nonlinear biodynamic response of the human body exposed to whole-body vibration [PDF]

open access: yes, 2008
When the human body is exposed to mechanical vibration, the resonance frequencies of the frequency response functions, such as apparent mass and transmissibility, decrease with increasing magnitude of excitation. For the past two decades, this biodynamic
