Modular Fabrication of Quantum‐Dot–Plasmonic Metasurfaces for Tailored Optical Modes

Small Structures, Volume 7, Issue 5, May 2026.
Our modular photonic architecture is illustrated using color‐coded building blocks representing colloidal quantum dots, gold nanoparticles, and thin films. This visual metaphor highlights our bottom‐up and top‐down fabrication approach, enabling the creation of tailored optical modes for optoelectronic applications.

“Caterpillar” ULF Waves in the Dusk Side Sub‐Auroral Region: Conjugate Observations With SuperDARN, Arase and Ground Magnetometers

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract On 23 November 2022, during exceptionally quiet geomagnetic conditions, a distinct ultra‐low frequency (ULF) wave in the Pc5 band (∼2.4 mHz) was observed in the duskside sub‐auroral region by two Canadian SuperDARN (Super Dual Auroral Radar Network) radars.

Mapping Subsea Permafrost Distribution in the Canadian Beaufort Sea With Marine Seismic and Deep Learning

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Subsea permafrost is widespread across the polar continental shelf, and mapping its distribution is crucial for assessing the possible impact of its degradation in response to global warming. While seismic techniques have been useful in determining the lateral extent of subsea permafrost in the Canadian Beaufort Sea, are limited when it comes ...

Surface roughness impact of 3D Ti-alloy printed WR-10 waveguide and rectangular horn antenna at W-band (75-110 GHz)

Micro and Nano Systems Letters
To investigate the effect of the surface roughness of 3D-metal-printed sub-THz components, the WR-10 3-inch-long waveguide and 24 dBi rectangular horn antenna were 3D-metal-printed using a titanium alloy powder and a high-resolution 3D metal printer. The

Phase and absorbance retrieval in X‐ray holographic microscopy under weak illumination using physics‐driven neural networks

Journal of Synchrotron Radiation, Volume 33, Issue 3, Page 794-805, May 2026.
A physics‐driven deep learning model enables single‐shot retrieval of 3D phase and absorbance from shot‐noise‐limited hard X‐ray holograms. Validated on both synthetic and experimental data, it provides robust reconstruction under weak illumination.X‐ray holographic microscopy is a three‐dimensional (3D) imaging technique for nanoscale‐resolution ...

Weather Regime Diversity, Transitions, and Trends Using Hexagonal Self‐Organizing Maps

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract Persistent atmospheric circulation patterns, or weather regimes, strongly modulate surface weather and extremes, yet their internal diversity, transitions, and trends remain less understood for North America. We apply a self‐organizing map (SOM) framework to represent North American weather regimes using daily 500‐hPa geopotential height ...
