Active microphase separation in mixtures of microtubules and tip-accumulating molecular motors

Posted by klaurent Harvard

Kavli Affiliate: Daniel J. Needleman | First 5 Authors: Bezia Lemma, Noah P. Mitchell, Radhika Subramanian, Daniel J. Needleman, Zvonimir Dogic | Summary: Mixtures of microtubules and molecular motors form active materials with diverse dynamical behaviors that vary based on their constituents’ molecular properties. We map the non-equilibrium phase diagram of microtubules and tip-accumulating kinesin-4 […]

Reverberation in tidal disruption events: dust echoes, coronal emission lines, multi-wavelength cross-correlations, and QPOs

Posted by klaurent MIT

Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Sjoert van Velzen, Dheeraj R. Pasham, Stefanie Komossa, Lin Yan, Erin A. Kara | Summary: Stellar tidal disruption events (TDEs) are typically discovered by transient emission due to accretion or shocks of the stellar debris. Yet this luminous flare can be reprocessed by gas or dust […]

On the Quantum Performance Evaluation of Two Distributed Quantum Architectures

Posted by klaurent Delft

Kavli Affiliate: Stephanie Wehner | First 5 Authors: Gayane Vardoyan, Matthew Skrzypczyk, Stephanie Wehner, , | Summary: Distributed quantum applications impose requirements on the quality of the quantum states that they consume. When analyzing architecture implementations of quantum hardware, characterizing this quality forms an important factor in understanding their performance. Fundamental characteristics of quantum hardware […]

Discovery of multiple p-mode pulsation frequencies in the roAp star, HD 86181

Posted by klaurent Peking

Kavli Affiliate: Huawei Zhang | First 5 Authors: Fangfei Shi, Donald W. Kurtz, Daniel L. Holdsworth, Hideyuki Saio, Margarida S. Cunha | Summary: We report the frequency analysis of a known roAp star, HD 86181 (TIC 469246567), with new inferences from TESS data. We derive the rotation frequency to be $nu_{rot}$ = 0.48753 $pm$ 0.00001d$^{-1}$. […]

Kavli Affiliate: Herre S. J. Van Der Zant | First 5 Authors: Javier López-Cabrelles, Samuel Mañas-Valero, Iñigo J. Vitórica-Yrezábal, Makars Šiškins, Martin Lee | Summary: Through rational chemical design, and thanks to the hybrid nature of metal-organic frameworks (MOFs), it is possible to prepare molecule-based 2D magnetic materials stable at ambient conditions. Here, we illustrate […]

Using a Cross-Task Grid of Linear Probes to Interpret CNN Model Predictions On Retinal Images

Posted by klaurent Harvard

Kavli Affiliate: Michael P. Brenner | First 5 Authors: Katy Blumer, Subhashini Venugopalan, Michael P. Brenner, Jon Kleinberg, | Summary: We analyze a dataset of retinal images using linear probes: linear regression models trained on some "target" task, using embeddings from a deep convolutional (CNN) model trained on some "source" task as input. We use […]

Identifying Majorana vortex modes via non-local transport

Posted by Berkeley

Kavli Affiliate: Joel E. Moore | First 5 Authors: Björn Sbierski, Max Geier, An-Ping Li, Matthew Brahlek, Robert G. Moore | Summary: The combination of two-dimensional Dirac surface states with s-wave superconductivity is expected to generate localized topological Majorana zero modes in vortex cores. Putative experimental signatures of these modes have been reported for heterostructures […]

Broadband X-Ray Observations of the 2018 Outburst of the Changing-Look Active Galactic Nucleus NGC 1566

Posted by klaurent Peking

Kavli Affiliate: Claudio Ricci | First 5 Authors: Arghajit Jana, Neeraj Kumari, Prantik Nandi, Sachindra Naik, Arka Chatterjee | Summary: We study the nature of the changing-look Active Galactic Nucleus NGC 1566 during its June 2018 outburst. During the outburst, the X-ray intensity of the source rises up to ~25-30 times compared to its quiescent […]
