We report on microwave signal-mixing functionality for a fiber-based optoelectronic oscillator. Two wavelength division multiplexed (WDM) channels carrying RF signals at 1320 and 1312 nm are simultaneously upconverted/downconverted by the fiber-based optoelectronic oscillator. The conversion efficiency is found to be approximately −8 dB, and the incoming signals have no effects on the local osc...

We have constructed tapered fiber-optic microsensors with a tip diameter of less than 10 microm to measure profiles of backscattered light in biofilms, which are thin layers of micro-organisms firmly attached to surfaces. The observed response agrees well with local effective diffusivity microelectrode measurements, with R(2) > 0.85. A strong relation between signal intensity and wavelength has...

Coherent π+π−π− production in the interactions of a beam of 600GeV π mesons with C, Cu and Pb nuclei has been studied with the SELEX facility (Experiment E781 at Fermilab). The a2(1320) meson signal has been detected in the Coulomb (low q2) region. The Primakoff formalism used to extract radiative decay width of this meson yields Γ = 284± 25± 25 keV, which is the most precise measurement to

We experimentally demonstrate a high pressure sensor based on a polarization-maintaining photonic crystal fiber (PMPCF) with Sagnac loop configuration for downhole application. The pressure sensitivity of the proposed sensor is 4.21 nm/MPa and 3.27 nm/MPa at ~1320 nm and ~1550 nm respectively. High pressure measurement up to 20 MPa has been achieved in our experiment. The sensor also shows redu...

Jarvis et al. (Research Articles, 12 December 2014, p. 1320) presented molecular clock analyses that suggested that most modern bird orders diverged just after the mass extinction event at the Cretaceous-Paleogene boundary (about 66 million years ago). We demonstrate that this conclusion results from the use of a single inappropriate maximum bound, which effectively precludes the Cretaceous div...

The poly(l-proline) II (PPII) helix is considered to be a major conformation in disordered polypeptides and unfolded proteins in aqueous solution. The PPII conformation can be identified by using Raman optical activity (ROA), which measures the different intensities of right- and left-circularly polarized Raman scattered light from chiral molecules and provides information on stereochemistry as...
