PMID: 22919461
Photonics Lett Pol. 2011 Jan 01;3(4):132-134. doi: 10.4302/plp.2011.4.02.

We demonstrate an application of high-speed swept source optical coherence tomography for vessel visualization in the anterior segment of the human eye. The human corneo-scleral junction and sclera was imaged in vivo. Imaging was performed using a swept source...

Cytotechnology. 2012 Aug;64(4):379-89. doi: 10.1007/s10616-011-9408-z. Epub 2012 Mar 22.

Although isolation and characterization of embryonic stem cells have been successful in cattle, maintenance of bovine embryonic stem cells in culture remains difficult. In this study, we compared different methods of cell passaging, feeder cell layers and medium conditions...

Simultaneous utilization of glucose and xylose for lipid production by Trichosporon cutaneum.

Biotechnology for biofuels

Hu C, Wu S, Wang Q, Jin G, Shen H, Zhao ZK.
PMID: 21864398
Biotechnol Biofuels. 2011 Aug 24;4(1):25. doi: 10.1186/1754-6834-4-25.

BACKGROUND: Biochemical conversion of lignocellulose hydrolysates remains challenging, largely because most microbial processes have markedly reduced efficiency in the presence of both hexoses and pentoses. Thus, identification of microorganisms capable of efficient and simultaneous utilization of both glucose and...

Measurement and reconstruction of three-dimensional configurations of specimen with tiny scattering based on digital holographic tomography.

Applied optics

Chen X, Zhao J, Wang J, Di J, Wu B, Liu J.
PMID: 24979439
Appl Opt. 2014 Jun 20;53(18):4044-8. doi: 10.1364/AO.53.004044.

Based on digital holographic tomography, a method for measuring the three-dimensional (3D) configuration of a transparent object with tiny scattering is proposed. By rotating a Michelson interferometer around static specimen, a series of the phase change distributions of reconstructed...

Stable radio frequency dissemination by simple hybrid frequency modulation scheme.

Optics letters

Yu L, Wang R, Lu L, Zhu Y, Wu C, Zhang B, Wang P.
PMID: 26466244
Opt Lett. 2014 Sep 15;39(18):5255-8. doi: 10.1364/OL.39.005255.

In this Letter, we propose a fiber-based stable radio frequency transfer system by a hybrid frequency modulation scheme. Creatively, two radio frequency signals are combined and simultaneously transferred by only one laser diode. One frequency component is used to...

Topological insulators with SU(2) Landau levels.

Physical review letters

Li Y, Zhang SC, Wu C.
PMID: 24237548
Phys Rev Lett. 2013 Nov 01;111(18):186803. doi: 10.1103/PhysRevLett.111.186803. Epub 2013 Oct 30.

We construct continuum models of 3D and 4D topological insulators by coupling spin-1/2 fermions to an SU(2) background gauge field, which is equivalent to a spatially dependent spin-orbit coupling. Higher dimensional generalizations of flat Landau levels are obtained in...

Use of Multiple Sequencing Technologies To Produce a High-Quality Genome of the Fungus Pseudogymnoascus destructans, the Causative Agent of Bat White-Nose Syndrome.

Genome announcements

Drees KP, Palmer JM, Sebra R, Lorch JM, Chen C, Wu CC, Bok JW, Keller NP, Blehert DS, Cuomo CA, Lindner DL, Foster JT.
PMID: 27365344
Genome Announc. 2016 Jun 30;4(3). doi: 10.1128/genomeA.00445-16.

White-nose syndrome has recently emerged as one of the most devastating wildlife diseases recorded, causing widespread mortality in numerous bat species throughout eastern North America. Here, we present an improved reference genome of the fungal pathogen Pseudogymnoascus destructans for...

Self-assembled structures of anionic hydrophobically modified polyacrylamide with star-shaped trimeric and hexameric quaternary ammonium surfactants.

Langmuir : the ACS journal of surfaces and colloids

Fan Y, Wu C, Wang M, Wang Y, Thomas RK.
PMID: 24866373
Langmuir. 2014 Jun 17;30(23):6660-8. doi: 10.1021/la501010s. Epub 2014 Jun 05.

The self-assembly of a 1% hydrophobically modified and 30% hydrolyzed polyacrylamide (C12PAM) with cationic star-shaped oligomeric surfactants has been investigated by isothermal titration microcalorimetry, turbidimetry, ΞΆ potential, scanning electron microscopy, and (1)H NMR techniques. The oligomeric surfactants are composed...

Diffusion-based three-dimensional reconstruction of complex surface using monocular vision.

Optics express

Wei Y, Wu C, Wang Y, Wang W.

Opt Express. 2015 Nov 16;23(23):30364-78. doi: 10.1364/OE.23.030364.

Three-dimensional (3D) reconstruction based on optical diffusion has certain significant advantages, such as its capacity for high-precision depth estimation with a small lens, distant-object depth estimation, a monocular vision basis, and no required camera or scene adjustment. However, few...
