Epithelial morphogenesis generates the shape of tissues, organs and embryos and is fundamental for their proper function. It is a dynamic process that occurs at multiple spatial scales from macromolecular dynamics, to cell deformations, mitosis and apoptosis, to coordinated cell rearrangements that lead to global changes of tissue shape. Using time lapse imaging, it is possible to observe these...

Recent studies with brain magnetic resonance imaging (MRI) have scanned large numbers of children and adolescents repeatedly over time, as their brains develop, tracking volumetric changes in gray and white matter in remarkable detail. Focusing on gray matter changes specifically, here we explain how earlier studies using lobar volumes of specific anatomical regions showed how different lobes o...

Methodological challenges have long been an obstacle for the understanding of damage in concrete due to alkali-silica reaction (ASR). Time-lapse X-ray tomography could be key advancements but has not extensively exploited, mainly similar electron densities different material phases, which leads poor contrast tomograms. To address this limitation, we propose implementation two complementary agen...

The Cianten Caldera in Indonesia is immediately adjacent to the producing portion of the Awibengkok geothermal field. The Cianten Caldera contains rocks similar to those in the Awibengkok field, however, the Cianten Caldera is not capable of producing geothermal power on a commercial scale. The Cianten Caldera has been microseismically monitored along with the producing Awibengkok field as inje...

Wave atoms are a low-redundancy alternative to curvelets, suitable for high-dimensional seismic data processing. This abstract extends the wave atom orthobasis construction to 3D, 4D, and 5D Cartesian arrays, and parallelizes it in a sharedmemory environment. An implementation of the algorithm for NVIDIA CUDA capable graphics processing units (GPU) is also developed to accelerate computation fo...

In part II of this two-part tutorial we review the underlying theory of seismic interferometry and discuss various new advances. In the 1990’s the method of time-reversed acoustics was developed. This method employs the fact that the acoustic wave equation for a lossless medium is invariant for time-reversal. When ultrasonic responses recorded by piezoelectric transducers are reversed in time a...
