All-optical photon echo and memory on a chip

, 2016
We demonstrate that a photon echo can be implemented by all-optical means using an array of on-chip high-finesse ring cavities whose parameters are chirped in such a way as to support equidistant spectra of cavity modes. When launched into such a system,

Ultrafast in‐memory computing and highly efficient deep neural networks driven by phase‐change memory materials with partially amorphous state transitions

InfoScience, EarlyView.
This work addresses challenges including the nonlinear weight‐conductance update and the trade‐off between increasing melting uniformity and reducing solid‐to‐liquid transition time. It utilizes all four melting states to create an integrated framework for attaining in‐memory computing and deep neural network applications. The framework achieves a near‐

3D Automated Segmentation of Bronchial Abnormalities on Ultrashort Echo Time MRI: A Quantitative MR Outcome in Cystic Fibrosis

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Cystic fibrosis (CF) monitoring relies on computed tomography (CT), but ultra‐short echo time MRI (UTE‐MRI) offers a radiation‐free alternative. However, its clinical adoption is hindered by the laborious and subjective manual analysis, which prevents standardized quantification of bronchial abnormalities.

Renal function impairment in children with intestinal failure receiving parenteral nutrition: A descriptive cohort study

Journal of Parenteral and Enteral Nutrition, EarlyView.
Abstract Background Children with intestinal failure are at risk for kidney dysfunction; however, the contributing factors are not well established. We aimed to describe risk factors associated with glomerular and tubular renal dysfunction in children with intestinal failure.

Photo‐Excitations in Halide Perovskites: Where Do Simulations and Experiments Meet?

Laser &Photonics Reviews, EarlyView.
Aiming to bridge the gap between simulations and measurements of light–matter couplings and photo‐excitations in new functional materials, this perspective highlights insights and bottlenecks of state‐of‐the‐art experimental and theoretical methods (2D electronic spectroscopy vs.

In-Situ Far-Field Calibration of Multibeam Sonar Arrays for Precise Backscatter Imagery [PDF]

, 1996
Calibration of large hull-mounted sonar transducer arrays is usually done by measuring the performance of individual components in a test tank. Multiple transducer element beam patterns are superimposed and combined with window attenuation and other ...

Dispersion‐Less Dissipative Soliton Fiber Laser

Laser &Photonics Reviews, EarlyView.
A dispersion‐less fiber laser architecture generates high‐energy, pedestal‐free picosecond pulses without resorting to conventional pulse stretching. This energy‐managed laser achieves remarkable flexibility in pulse parameters, delivering up to 0.54 μJ$\mathrm{\mu}\mathrm{J}$ pulses with minimal spectral distortion using standard telecom components ...
