Experimental investigation of different regimes of mode-locking in a high repetition rate passively mode-locked semiconductor quantum-dot laser.

Optics express

Kéfélian F, O'Donoghue S, Todaro MT, McInerney J, Huyet G.
PMID: 19365451
Opt Express. 2009 Apr 13;17(8):6258-67. doi: 10.1364/oe.17.006258.

We report experimental investigations on a two-section 16-GHz repetition rate InAs/GaAs quantum dot passively mode-locked laser. Near the threshold current, pseudo-periodic Q-switching with complex dynamics is exhibited. Mode-locking operation regimes characterized by different repetition rates and timing jitter levels...

Designing for reliable textile neonatal ECG monitoring using multi-sensor recordings.

Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual International Conference

Bouwstra S, Chen W, Oetomo SB, Feijs LM, Cluitmans PJ.
PMID: 22254846
Annu Int Conf IEEE Eng Med Biol Soc. 2011;2011:2488-91. doi: 10.1109/IEMBS.2011.6090690.

When designing an ECG monitoring system embedded with textile electrodes for comfort, it is challenging to ensure reliable monitoring, because textile electrodes suffer from motion artifacts and incidental poor signal quality. For the design of a comfortable monitoring system...

Simplified Dual-Lumen Catheter-Facilitated Reverse Wire Technique for Markedly Angulated Collateral Channel Entry in Retrograde Chronic Total Occlusion Intervention.

International heart journal

Wu K, Luo B, Huang Z, Zhang B.
PMID: 33678795
Int Heart J. 2021 Mar 30;62(2):416-421. doi: 10.1536/ihj.20-391. Epub 2021 Mar 06.

The retrograde approach has significantly improved the success rates in complex coronary total occlusion (CTO) lesions. It has also become the predominant and important strategy in CTO recanalization. However, unsuccessful crossing of the collateral channels is the strongest predictor...

Subnanometric stabilization of plasmon-enhanced optical microscopy.

Nanotechnology

Yano TA, Ichimura T, Kuwahara S, Verma P, Kawata S.
PMID: 22543309
Nanotechnology. 2012 May 25;23(20):205503. doi: 10.1088/0957-4484/23/20/205503. Epub 2012 Apr 30.

We have demonstrated subnanometric stabilization of tip-enhanced optical microscopy under ambient condition. Time-dependent thermal drift of a plasmonic metallic tip was optically sensed at subnanometer scale, and was compensated in real-time. In addition, mechanically induced displacement of the tip,...

Design and characterization of a 3D-printed staggered herringbone mixer.

BioTechniques

Shenoy VJ, Edwards CE, Helgeson ME, Valentine MT.
PMID: 34000813
Biotechniques. 2021 May;70(5):285-289. doi: 10.2144/btn-2021-0009. Epub 2021 May 18.

3D printing holds potential as a faster, cheaper alternative compared with traditional photolithography for the fabrication of microfluidic devices by replica molding. However, the influence of printing resolution and quality on device design and performance has yet to receive...

Current and future drug-eluting coronary stent technology.

Expert review of cardiovascular therapy

Ielasi A, Latib A, Colombo A.
PMID: 21517732
Expert Rev Cardiovasc Ther. 2011 Apr;9(4):485-503. doi: 10.1586/erc.11.5.

Despite the impressive benefits obtained following the introduction of the drug-eluting stent, safety concerns have been raised over their long-term safety with particular regard to stent thrombosis. Various mechanisms such as delayed endothelialization, local hypersensitivity and endothelial dysfunction owing...

Plasmon Waveguide Resonance: Principles, Applications and Historical Perspectives on Instrument Development.

Molecules (Basel, Switzerland)

Rascol E, Villette S, Harté E, Alves ID.
PMID: 34770851
Molecules. 2021 Oct 26;26(21). doi: 10.3390/molecules26216442.

Plasmon waveguide resonance (PWR) is a variant of surface plasmon resonance (SPR) that was invented about two decades ago at the University of Arizona. In addition to the characterization of the kinetics and affinity of molecular interactions, PWR possesses...
