Unsteady blade pressures on a propfan: Predicted and measured compressibility effects [PDF]

open access: yes
The effect of compressibility on unsteady blade pressures is studied by solving the three-dimensional Euler equations. The operation of the eight-bladed SR7L propfan at a 4.75 deg angle of attack was considered.

High‐Precision Automated Setting of Arbitrary Magnitude and Phase of Mach–Zehnder Interferometers for Scalable Optical Computing

open access: yesLaser &Photonics Reviews, EarlyView.
This work presents a novel technique to control photonic accelerators based on integrated Mach–Zehnder interferometers, enabling resolutions of 7.01 and 8.04 bits for the output power and phase setting. The technique uses local feedback loops that ensure precise calibration‐free programming of the device transfer function, enabling highly accurate ...

The Relationships Between Facets of Emotional Intelligence and Facets of the Dark Triad. [PDF]

open access: yesInt J Psychol
ABSTRACT Investigations of the Dark Triad traits and trait emotional intelligence (EI) have not closely examined potentially meaningful relationships among these traits at the facet level. The goal of this study was to examine these associations in greater detail by assessing the relationships between factors of trait EI and facets of the Dark Triad ...

A MHz−Level Swept Source by Time Stretching the Shot−Noise Limited Supercontinuum Based on a Mode−Locked Laser and the Application in Optical Coherence Tomography

open access: yesLaser &Photonics Reviews, EarlyView.
This work pioneers a 5.7 MHz all−fiber mode−locked laser−based broadband swept−source OCT system, achieving record−breaking performance: 11.4 µm axial resolution and 119 mm detection range. The system demonstrates exceptional coherence and stability, overcoming traditional trade−off between imaging speed and detection range.

Nonlinear Distortion Equalization in Multi‐Span Optical Links Via a Feed‐Forward Photonic Neural Network

open access: yesLaser &Photonics Reviews, EarlyView.
A feed‐forward photonic neural network equalizes linear and nonlinear impairments in multi‐span IMDD optical fiber transmission. The linear processing stage employs an 8‐tap optical Finite Impulse Response filter integrated on a silicon photonics platform, while the end‐of‐line photodetector represents the nonlinear stage.
