Seeing the invisible: the challenge of imaging vitreous.

Design and fabrication of a high-Q near-field probe for subsurface crack detection

Non-destructive detection and evaluation of invisible cracks in metal structures is an important matter in several critical environments including ground transportation, air transportation and power plants. In this paper, a high-Q near-field Microwave probe is designed and fabricated using defected ground structures for surface and subsurface crack detection in metal structures. For this purpos...

Creation the fully integrated and flourishing assessment challenge award: Integration is the key

Medicine is now undertaking a paramount revolution that will alter the nature of healthcare from reactive to proactive. It is imperative to integrate experimental and computational investigation in order to appreciate complex biological systems in the era of precision medicine. In light of this revolution, we necessitate to precision medicine means such as systems approaches (genomics, radiogen...

Classifying posterior vitreous detachment: a new way to look at the invisible.

Vitreous Anatomy and Pathology

Although vitreous is the largest structure within the eye, constituting 80% of the ocular volume, investigators of vitreous anatomy are hampered by two fundamental diffi culties: ● Any attempts to defi ne vitreous morphology are efforts to “visualize” a tissue that is invisible by design ( Fig. 6-46-1 ). ● The various techniques that were employed previously to defi ne vitreous structure were f...

Numerical simulation of the fluid dynamics in a 3D spherical model of partially liquefied vitreous due to eye movements under planar interface conditions

Partially liquefied vitreous humor is a common physical and biochemical degenerative change in vitreous body which the liquid component gets separated from collagen fiber network and leads to form a region of liquefaction. The main objective of this research is to investigate how the oscillatory motions influence flow dynamics of partial vitreous liquefaction (PVL). So far computational fluid d...
