The validity of "Odd and Even" channels for testing all-optical OFDM and Nyquist WDM long-haul fiber systems.

Optics express

Du LB, Lowery AJ.
PMID: 23262886
Opt Express. 2012 Dec 10;20(26):B445-51. doi: 10.1364/OE.20.00B445.

We investigate experimentally the validity of testing all-optical OFDM and Nyquist WDM systems using interleaved test channels derived from only two data sources. These "odd and even" channels are insufficiently decorrelated, so experiments underestimate the inter-carrier interference (ICI). Additionally,...

Organocatalytic asymmetric selenofunctionalization of tryptamine for the synthesis of hexahydropyrrolo[2,3-b]indole derivatives.

Beilstein journal of organic chemistry

Wei Q, Wang YY, Du YL, Gong LZ.
PMID: 23946855
Beilstein J Org Chem. 2013 Aug 01;9:1559-64. doi: 10.3762/bjoc.9.177. eCollection 2013.

A chiral phosphoric acid-catalyzed selenofunctionalization of tryptamine derivatives provides access to 3a-(phenylselenyl)-1,2,3,3a,8,8a-hexahydropyrrolo[2,3-b]indole derivatives in high yields and with synthetically useful levels of enantioselectivity (up to 89% ee).

Controllable fabrication of patterned ZnO nanorod arrays: investigations into the impacts on their morphology.

ACS applied materials & interfaces

Zhang DB, Wang SJ, Cheng K, Dai SX, Hu BB, Han X, Shi Q, Du ZL.
PMID: 22612251
ACS Appl Mater Interfaces. 2012 Jun 27;4(6):2969-77. doi: 10.1021/am3003473. Epub 2012 May 21.

Fabricating ZnO nanorod arrays with precisely controlled morphology, alignment, and density is highly desirable but rather challenging. On the other hand, understanding the parameters that affect their final morphology and the growth mechanisms is significant to integrate such patterned...

Pilot-based XPM nonlinearity compensator for CO-OFDM systems.

Optics express

Du LB, Lowery AJ.
PMID: 22274114
Opt Express. 2011 Dec 12;19(26):B862-7. doi: 10.1364/OE.19.00B862.

We experimentally verify that pilot-based nonlinearity compensation is effective for mitigating XPM in CO-OFDM systems, if SPM is compensated first. A 6-dB increase in the nonlinear limit was produced by pilot-based XPM compensation after a single-step SPM compensator in...

Solution fabrication and photoelectrical properties of CuInS₂ nanocrystals on TiO₂ nanorod array.

ACS applied materials & interfaces

Zhou ZJ, Fan JQ, Wang X, Sun WZ, Zhou WH, Du ZL, Wu SX.
PMID: 21688822
ACS Appl Mater Interfaces. 2011 Jul;3(7):2189-94. doi: 10.1021/am200500k. Epub 2011 Jun 24.

One-dimensional semiconductor architectures are receiving attention in preparing photovoltaic solar cells because of its superior charge transport as well as excellent light-harvesting efficiency. In this study, vertically aligned single-crystalline TiO(2) nanorods array was grown directly on transparent conductive glass...

Prolonged Combination Therapy is More Effective than Monotherapy in Management of Chronic Hepatitis B Patients With Sustained Virological Response: An Experience From a 'Real-World' Clinical Setting.

Iranian Red Crescent medical journal

Chen EQ, Bai L, Chen LL, Zhou TY, Du LY, Tang H.
PMID: 24693412
Iran Red Crescent Med J. 2013 Dec;15(12):e7788. doi: 10.5812/ircmj.7788. Epub 2013 Dec 05.

BACKGROUND: Little is known about the duration of combination therapy for patients with chronic hepatitis B (CHB) and suboptimal response to nucleos(t)ide analogues(NAs) monotherapy.OBJECTIVES: This study aimed to assess whether monotherapy could be used for treatment of CHB patients,...

Safety and efficacy of intravenous esmolol before prospective electrocardiogram-triggered high-pitch spiral acquisition for computed tomography coronary angiography.

Journal of geriatric cardiology : JGC

Wang JD, Zhang HW, Xin Q, Yang JJ, Sun ZJ, Liu HB, Chen L, Du LS, Chen YD.
PMID: 24748880
J Geriatr Cardiol. 2014 Mar;11(1):39-43. doi: 10.3969/j.issn.1671-5411.2014.01.011.

BACKGROUND: In order to acquire a high quality image with a low radiation dose, prospective electrocardiogram (ECG)-triggered computed tomography coronary angiography (CTCA) requires a stable heart rate (HR) < 65 beats/min. Esmolol has the advantage of reducing HR. The...

[Modeling continuous scaling of NDVI based on fractal theory].

Guang pu xue yu guang pu fen xi = Guang pu

Luan HJ, Tian QJ, Yu T, Hu XL, Huang Y, Du LT, Zhao LM, Wei X, Han J, Zhang ZW, Li SP.
PMID: 24059189
Guang Pu Xue Yu Guang Pu Fen Xi. 2013 Jul;33(7):1857-62.

Scale effect was one of the very important scientific problems of remote sensing. The scale effect of quantitative remote sensing can be used to study retrievals' relationship between different-resolution images, and its research became an effective way to confront...

Comparative analysis of the effects of ultrasound-targeted microbubble destruction on recombinant adeno-associated virus- and plasmid-mediated transgene expression in human retinal pigment epithelium cells.

Molecular medicine reports

Zheng XZ, Wu Y, Li HL, Du LF, Wang HP, Gu Q.
PMID: 21475924
Mol Med Rep. 2009 Nov-Dec;2(6):937-42. doi: 10.3892/mmr_00000195.

Ultrasound-targeted microbubble destruction (UTMD) has been utilized to deliver a drug/gene into cells in both in vitro and in vivo studies. This study was performed to investigate the feasibility of UTMD-enhanced recombinant adeno-associated virus- (rAAV) and plasmid-mediated transfection into...
