Efficient binary phase quantizer based on phase sensitive four wave mixing [PDF]

open access: yes, 2014
We experimentally demonstrate an efficient binary phase quantizer operating at low pump powers. Phase-sensitive operation is obtained by polarization mixing the phase-locked signal/idler pair in a degenerate dual-pump vector parametric ...

Dual-phase ionic-conducting membranes: Pressure dependence of gas permeation flux

open access: yesJournal of Membrane Science Letters, 2023
Pressure dependence of gas permeation flux for dual-phase ionic-conducting membranes is critical to the design and operation of separation or reaction processes using these membranes.

Single phase computed tomography is equivalent to dual phase method for localizing hyperfunctioning parathyroid glands in patients with primary hyperparathyroidism: a retrospective review [PDF]

open access: yesPeerJ, 2017
Objective This study aims to compare the sensitivity of dual phase (non-contrast and arterial) versus single phase (arterial) CT for detection of hyper-functioning parathyroid glands in patients with primary hyperparathyroidism.

Strain Rate Sensitivity of a TRIP-Assisted Dual-Phase High-Entropy Alloy

open access: yesFrontiers in Materials, 2018
Dual-phase high-entropy alloys (DP-HEAs) with transformation induced plasticity (TRIP) have an excellent strength-ductility combination. To reveal their strain-rate sensitivity and hence further understand the corresponding deformation mechanisms, we ...

Dual-Polarization Phase Retrieval Receiver in Silicon Photonics

open access: yes, 2023
We demonstrate a silicon photonic dual-polarization phase retrieval receiver. The receiver recovers phase from intensity-only measurements without a local oscillator or transmitted carrier. We design silicon waveguides providing long delays and microring

Deformation mechanisms and work-hardening behavior of transformation-induced plasticity high entropy alloys by in -situ neutron diffraction

open access: yesMaterials Research Letters, 2018
A full picture of tensile deformation mechanism evolution in the FCC-to-HCP transformation-induced plasticity high entropy alloy (TRIP-HEA) was revealed by real-time in situ neutron diffraction. Three transition points, i.e. the triggering of TRIP in the

Pseudocoloring for a dual‐phase grating method [PDF]

open access: yesOptical Engineering, 1996
A simple method for adjusting pseudocolor distributions of photographic images is described and demonstrated experimentally. This method is based on the technique for photographic phase image pseudocolor modulated by a grating. A reflecting ray path is introduced into a 4f system to produce diffraction of the dual-phase grating so that the pseudocolor ...

Ultrafine-grained dual phase Al0.45CoCrFeNi high-entropy alloys

open access: yesMaterials & Design, 2019
A duplex microstructure consisting of body-centered-cubic (BCC/B2) and face-centered-cubic (FCC) phases was observed after homogenization and recrystallization treatments in Al0.45CoCrFeNi high-entropy alloys (HEAs).
