PMID: 25969244
Opt Express. 2015 May 04;23(9):11493-507. doi: 10.1364/OE.23.011493.

The paper reports on the coupling of Parity-Time (PT)-symmetric whispering gallery resonators with realistic material and gain/loss models. Response of the PT system is analyzed for the case of low and high material and gain dispersion, and also for...

INTRODUCTION: Inferior vena cava collapsibility index (IVC-CI) has been shown to correlate with both clinical and invasive assessment of intravascular volume status, but has important limitations such as the requirement for advanced sonographic skills, the degree of difficulty in...

Focusing monochromator and imaging-plate camera for grazing-incidence diffraction studies of thin films.

Journal of synchrotron radiation

Foran GJ, Garrett RF, Gentle IR, Creagh DC, Peng JB, Barnes GT.
PMID: 15263558
J Synchrotron Radiat. 1998 May 01;5:500-2. doi: 10.1107/S0909049597017287. Epub 1998 May 01.

A multiple-imaging-plate detector system and focusing monochromator have been developed and successfully applied to the time-resolved study of phase transitions in Langmuir-Blodgett films by grazing-incidence X-ray diffraction (GIXD). The monochromator described here combines fixed-exit-beam height with sagittal focusing of...

Synchrotron radiation study of the relation between structure and strain in polyurethane elastomers.

J Synchrotron Radiat. 1997 May 01;4:163-8. doi: 10.1107/S0909049597003245.

This paper describes a system for the study of the relation between structure and applied strain in thermoplastic polyurethane elastomers using the Australian National Beamline Facility at the Photon Factory, KEK, Tsukuba, Japan. The system uses the sagittal focusing...

Application of imaging-grazing-incidence X-ray diffraction and specular reflectivity to the structural investigation of quantum-confinement semiconductor devices.

Journal of synchrotron radiation

Holt SA, Brown AS, Creagh DC, Leon R.
PMID: 16699224
J Synchrotron Radiat. 1997 May 01;4:169-74. doi: 10.1107/S0909049597004123.

X-ray reflectivity and grazing-incidence X-ray diffraction techniques have been employed to investigate the structure of quantum-well and quantum-dot semiconductor devices. This work has been performed using both laboratory and synchrotron radiation sources. The use of synchrotron radiation enabled reflectivity...

The induction of thrombus generation on nanostructured neutral polymer brush surfaces.

Biomaterials

Lai BF, Creagh AL, Janzen J, Haynes CA, Brooks DE, Kizhakkedathu JN.
PMID: 20638975
Biomaterials. 2010 Sep;31(26):6710-6718. doi: 10.1016/j.biomaterials.2010.05.052. Epub 2010 Jun 20.

Surface induced thrombus generation is a major clinical concern associated with vascular medical devices and implants. Here, we show that high graft density hydrophilic non-charged poly (N,N-dimethylacrylamide) (PDMA) brushes prevent the initiation of blood coagulation on synthetic surfaces. Using...

Pragmatic skills after childhood traumatic brain injury: Parents' perspectives.

Journal of communication disorders
