Kavli Affiliate: Mark J. Bowick | First 5 Authors: Suraj Shankar, Anton Souslov, Mark J. Bowick, M. Cristina Marchetti, Vincenzo Vitelli | Summary: Active matter encompasses different nonequilibrium systems in which individual constituents convert energy into non-conservative forces or motion at the microscale. This review provides an elementary introduction to the role of topology in […]
Kavli Affiliate: Cees Dekker | First 5 Authors: Nils Klughammer, Cees Dekker, , , | Summary: Holes in metal films block any transmitting light if the wavelength is much larger than the hole diameter, establishing such nanopores as so-called Zero Mode Waveguides (ZMWs). Molecules on the other hand, can still passage through these holes. We […]
Kavli Affiliate: Jiansheng Chen | First 5 Authors: Yiqing Huang, Jiansheng Chen, , , | Summary: Existing image captioning models are usually trained by cross-entropy (XE) loss and reinforcement learning (RL), which set ground-truth words as hard targets and force the captioning model to learn from them. However, the widely adopted training strategies suffer from […]
Kavli Affiliate: Erik Shirokoff | First 5 Authors: Joaquin Vieira, James Aguirre, C. Matt Bradford, Jeffrey Filippini, Christopher Groppi | Summary: Understanding the formation and evolution of galaxies over cosmic time is one of the foremost goals of astrophysics and cosmology today. The cosmic star formation rate has undergone a dramatic evolution over the course […]
Kavli Affiliate: Menno Veldhorst | First 5 Authors: Xiao Xue, Bishnu Patra, Jeroen P. G. van Dijk, Nodar Samkharadze, Sushil Subramanian | Summary: The most promising quantum algorithms require quantum processors hosting millions of quantum bits when targeting practical applications. A major challenge towards large-scale quantum computation is the interconnect complexity. In current solid-state qubit […]
Kavli Affiliate: Scott K. Cushing | First 5 Authors: Hung-Tzu Chang, Alexander Guggenmos, Scott K. Cushing, Yang Cui, Naseem Ud Din | Summary: Direct measurements of photoexcited carrier dynamics in nickel are made using few-femtosecond extreme ultraviolet (XUV) transient absorption spectroscopy at the nickel M$_{2,3}$ edge. It is observed that the core-level absorption lineshape of […]
Kavli Affiliate: Salvatore Vitale | First 5 Authors: Hsin-Yu Chen, Carl-Johan Haster, Salvatore Vitale, Will M. Farr, Maximiliano Isi | Summary: The identification of the electromagnetic counterpart candidate ZTF19abanrhr to the binary black hole merger GW190521 opens the possibility to infer cosmological parameters from this standard siren with a uniquely identified host galaxy. The distant […]
Kavli Affiliate: Robert F. Goeke | First 5 Authors: Kristo Ment, Jonathan Irwin, David Charbonneau, Jennifer G. Winters, Amber Medina | Summary: We present the discovery of TOI 540 b, a hot planet slightly smaller than Earth orbiting the low-mass star 2MASS J05051443-4756154. The planet has an orbital period of $P = 1.239149$ days ($pm$ […]
Kavli Affiliate: Roger W. Romani | First 5 Authors: Pavan R. Hebbar, Craig O. Heinke, D. Kandel, Roger W. Romani, | Summary: Redback millisecond pulsars (MSPs) typically show pronounced orbital variability in their X-ray emission due to our changing view of the intrabinary shock (IBS) between the pulsar wind and stellar wind from the companion. […]
Kavli Affiliate: Andrew M. Vanderburg | First 5 Authors: Theron W. Carmichael, Samuel N. Quinn, George Zhou, Nolan Grieves, Francois Bouchy | Summary: We report the discovery of two transiting brown dwarfs (BDs), TOI-811b and TOI-852b, from NASA’s Transiting Exoplanet Survey Satellite mission. These two transiting BDs have similar masses, but very different radii and […]
