Generating amplitude acoustic patterns by mechanically shifting the emitters of an array [PDF]
Acoustic patterns are employed for particle patterning, targeted therapeutic ultrasound, or 3D printing. Patterns are generated using phased-arrays that electronically control each emitter or using passive structures that modulate the wave-field.

Genome-wide nucleosome positioning is orchestrated by genomic regions associated with DNase I hypersensitivity in rice. [PDF]
Nucleosome positioning dictates the DNA accessibility for regulatory proteins, and thus is critical for gene expression and regulation. It has been well documented that only a subset of nucleosomes are reproducibly positioned in eukaryotic genomes.
