Cellulolytic potential under environmental changes in microbial communities from grassland litter.

Frontiers in microbiology

Berlemont R, Allison SD, Weihe C, Lu Y, Brodie EL, Martiny JB, Martiny AC.
PMID: 25505459
Front Microbiol. 2014 Nov 25;5:639. doi: 10.3389/fmicb.2014.00639. eCollection 2014.

In many ecosystems, global changes are likely to profoundly affect microorganisms. In Southern California, changes in precipitation and nitrogen deposition may influence the composition and functional potential of microbial communities and their resulting ability to degrade plant material. To...

Improved technique for the characterization of micro-ring resonator using low coherence measurement.

Optics letters

Liu WK, Chen CY, Wei CC, Chen YJ.
PMID: 26076293
Opt Lett. 2015 Jun 15;40(12):2909-12. doi: 10.1364/OL.40.002909.

Low-coherence interferometric measurement has been used to investigate optical waveguide devices with high accuracy. By utilizing an incoherent light source, one can generate separate interferogram features for each optical path. The distance between adjacent features of a ring resonator...

Frequency- and time-domain nonlinear distortion compensation in high-speed OFDM-IMDD LR-PON with high loss budget.

Optics express

Chen HY, Wei CC, Lin CY, Chen LW, Lu IC, Chen J.
PMID: 28380770
Opt Express. 2017 Mar 06;25(5):5044-5056. doi: 10.1364/OE.25.005044.

This study compared two nonlinear distortion compensation techniques, SSII cancellation (in the frequency domain) and Volterra filtering (in the time domain), in a >50-Gbps/λ OFDM-IMDD LR-PON. Experiment results for SNR, BER, and data rate (based on a bit-loading algorithm)...

Application of an optical pulse stretcher to coherent anti-Stokes Raman spectroscopy.

Optics letters

Beyrau F, Weikl MC, Seeger T, Leipertz A.
PMID: 15532274
Opt Lett. 2004 Oct 15;29(20):2381-3. doi: 10.1364/ol.29.002381.

An external optical cavity pulse stretcher for nanosecond-long laser pulses has been applied to coherent anti-Stokes Raman spectroscopy (CARS). An increased signal-to-noise ratio was achieved for both vibrational and pure rotational CARS, while the power density of the laser...

Two-photon stimulated Raman excitation of thermal laser-induced gratings in molecular gases using broadband radiation of a single laser.

Optics express

Kozlov DN, Weikl MC, Kiefer J, Seeger T, Leipertz A.
PMID: 18958116
Opt Express. 2008 Oct 27;16(22):18379-89. doi: 10.1364/oe.16.018379.

For the first time to our knowledge, thermal laser-induced gratings (LIGs), generated via two-photon stimulated Raman excitation of pure rotational (and low-lying vibrational) transitions in molecules employing broadband radiation of a single pump laser, are observed. The efficiency of...

Variation Analysis of Sphygmogram to Assess Cardiovascular System under Meditation.

Evidence-based complementary and alternative medicine : eCAM

Liu CY, Wei CC, Lo PC.
PMID: 18955219
Evid Based Complement Alternat Med. 2009 Mar;6(1):107-12. doi: 10.1093/ecam/nem065. Epub 2007 Jun 15.

In this article, we studied how meditation affects the characteristics of the cardiovascular system, mainly based on blood pressure waveforms (BPW). Four parameters derived from BPW include the rising slope (h(1)/t(1)), normalized height of T wave (h(3)/h(1)), normalized height...

Theoretical investigation of polarization-insensitive data format conversion of RZ-OOK to RZ-BPSK in a nonlinear birefringent fiber.

Optics express

Wei CC, Astar W, Chen J, Chen YJ, Carter GM.
PMID: 19293855
Opt Express. 2009 Mar 16;17(6):4306-16. doi: 10.1364/oe.17.004306.

Polarization-insensitive conversion of return-to-zero (RZ) ON-OFF keying (RZ-OOK) to RZ binary phase-shift keying (RZ-BPSK) has been achieved by cross-phase modulation (XPM) in a nonlinear birefringent fiber. This work presents a theoretical analysis of the dependence of format conversion on...
