Spatial Manipulation via Four-Wave Mixing in Five-Level Cold Atoms

Frontiers in Physics, 2022
In a recent publication [S. Gan, Laser Phys. 31, 055401 (2021)], a scheme for controlling the vortex four-wave mixing (FWM) in a five-level atomic system has been put forward.

Invited Article: Enhanced four-wave mixing in waveguides integrated with graphene oxide

APL Photonics, 2018
We demonstrate enhanced four-wave mixing (FWM) in doped silica waveguides integrated with graphene oxide (GO) layers. Owing to strong mode overlap between the integrated waveguides and GO films that have a high Kerr nonlinearity and low loss, the FWM ...

Three Methods of Fetal Weight Estimation Compared in Women With BMI ≥ 35 kg/m2 at Term—A Prospective Observational Study

Birth, EarlyView.
Visual summary of a prospective study comparing sonographic, maternal, and clinical fetal‐weight estimation methods in women with BMI = 35 kg/m2 at term. The graphical abstract presents the study objective, design, accuracy measures, and the primary finding that maternal and sonographic estimations demonstrated similar accuracy and both exceeded that ...

Polarization Control Methods for Mitigating Four-Wave Mixing Effect in NG-EPON Networks

Photonics
In order to meet the growing traffic demands, the formulation of the NG-EPON protocol is under heated discussion. Therefore, for the wavelength allocation scheme of NG-EPON, adopting O-band wavelengths is considered as the potentially feasible solution ...

L‐VISP: LSTM Visualization for Interpretable Symptom Prediction in Patient Cohorts

Computer Graphics Forum, EarlyView.
L‐VISP is a human‐machine solution that uses visual analytics for LSTM modelling in clinical research. L‐VISP uses custom visual encodings to make multiple LSTM variants interpretable, supporting a full range of analysis, from understanding model operations and evaluating performance to interpreting results in a clinical context.

Intra-cavity frequency shifted laser pumps for non-degenerate and partially coherent Bragg-Scattering FWM in nonlinear fiber [PDF]

, 2011
International audienceIn this work the authors experimentally study the problem of non-degenerate four-wave-mixing (FWM) by using a pair of partially coherent pumps, and focus our attention on a specific type of FWM, which is generally called "Bragg ...

Enhanced nonlinearity of four-wave mixing via Rydberg–Rydberg interactions

New Journal of Physics, 2022
We investigate the four-wave mixing (FWM) nonlinearity in an ensemble of cold Rydberg atoms with each of them regarded as a double-ladder system. The interaction is studied from the view of generating a signal field in virtue of three applied lasers ...

Visual Cues for Logical Reasoning about Text Enhance Metacognitive Sensitivity

Computer Graphics Forum, EarlyView.
Abstract An important part of critical thinking is analyzing the logical structure of inferences made in text, such as checking whether if–then rules appearing in legal regulations or scientific arguments are applied correctly. Metacognitive sensitivity, defined as feeling confident about one's correct answers and uncertain about incorrect ones, is an ...
