Nanoscale. 2016 Jun 09;8(23):11851-61. doi: 10.1039/c5nr09235c.

The research strategy described in this manuscript harnesses the attractive properties of hydrogels, gold nanorods (Aurods), and magnetic nanoparticles (MNPs) by synthesizing one unique multi-responsive nanostructure. This novel hybrid structure consists of silica-coated magnetic particles encapsulated within a thermo-responsive...

Target-in-the-loop wavefront sensing and control with a Collett-Wolf beacon: speckle-average phase conjugation.

Applied optics

PMID: 19107151
Appl Opt. 2009 Jan 01;48(1):A13-29. doi: 10.1364/ao.48.000a13.

Adaptive optical systems for laser beam projection onto an extended target embedded in an optically inhomogeneous medium are considered. A new adaptive optics wavefront control technique--speckle-average (SA) phase conjugation--is introduced. In this technique mitigation of speckle effects related to...

Adaptive phase-distortion correction based on parallel gradient-descent optimization.

Opt Lett. 1997 Jun 15;22(12):907-9. doi: 10.1364/ol.22.000907.

We describe an adaptive wave-front control technique based on a parallel stochastic perturbation method that can be applied to a general class of adaptive-optical system. The efficiency of this approach is analyzed numerically and experimentally by use of a...

Obscuration-free pupil-plane phase locking of a coherent array of fiber collimators.

PeerJ. 2018 Feb 02;6:e4299. doi: 10.7717/peerj.4299. eCollection 2018.

The systematics of grasses has advanced through applications of plastome phylogenomics, although studies have been largely limited to subfamilies or other subgroups of Poaceae. Here we present a plastome phylogenomic analysis of 250 complete plastomes (179 genera) sampled from...

In neutrophils, nicotinamide adenine dinucleotide phosphate (NADPH) generated via the pentose phosphate pathway fuels NADPH oxidase NOX2 to produce reactive oxygen species for killing invading pathogens. However, excessive NOX2 activity can exacerbate inflammation, as in acute respiratory distress syndrome...
