Revealing the Resonant Physics of Open Photonic Time Crystals

open access: yesLaser &Photonics Reviews, EarlyView.
ABSTRACT Photonic time crystals (PTCs) are media whose permittivity is modulated periodically in time, enabling momentum bandgaps and parametric amplification of light. Their realization at the nanoscale can revolutionize the study of light‐matter interactions.

Gender discrimination in physics and astronomy: Graduate student experiences of sexism and gender microaggressions

open access: yesPhysical Review Physics Education Research, 2016
[This paper is part of the Focused Collection on Gender in Physics.] Sexism occurs when men are believed to be superior to women, and is thought to be one of the reasons for women’s underrepresentation in physics and astronomy.

The Role of Projects in Astronomy Education [PDF]

open access: yesInternational Astronomical Union Colloquium, 1990
At first sight, there may appear to be a very wide range of project situations that are in use. Students may seem to be doing the equivalent of postgraduate work, or may seem to be working on contract basis, or may even seem to be doing rather long term laboratory exercises, or some mixture of all three. However, there are in essence two major types of

Astronomy Education in Slovenia

open access: yes, 1999
Astronomers in small groups are in a special position. Their research has to be on a similar level as in large astronomy communities, but on the other hand they should devote larger fraction of their time to public outreach and education duties ...

Four Directions, One Solution: Enabling Rapid Diffusion Tensor MRI for Ultra‐Low Field Using Deep Learning

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose This study revisits the tetrahedral encoding strategy originally proposed to accelerate Diffusion Tensor Magnetic Resonance Imaging (DT‐MRI) by reducing the requisite number of diffusion‐weighted measurements to four. We examine its practical limitations and explore how artificial intelligence (AI) can extend its utility. Specifically,

Astronomy Education Research: Developmental History of the Field and Summary of the Literature

open access: yes, 2011
Although astronomy topics have been included in K-12 education research for decades, astronomy education research as a field of discipline-based education research is relatively new.

The Need for Fundamental Photovoltaics Research to Ensure Energy Security

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
The center of this graphic focuses on the core of this paper—that fundamental research is central to the continued development of the photovoltaic (PV) industry. To the left, we have depictions of what is being studied—PV materials, PV cell structures, and PV module structures.

Near‐resonant excitation of the Adriatic barotropic modes: The seiche events of December 2019

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This study examines severe flooding in the northern Adriatic Sea in December 2019, which existing forecasting systems failed to predict. Analysis of wind and sea‐level data, alongside reanalysis datasets and a high‐resolution hydrodynamic model, revealed a wind‐induced resonance mechanism.
