Tip of the iceberg: overmassive black holes at 4<z<7 found by JWST are not inconsistent with the local $mathcal{M}_{rm BH}$-$mathcal{M}_star$ relation

Posted by dbos February 29, 2024Tokyo

Kavli Affiliate: John D. Silverman | First 5 Authors: Junyao Li, John D. Silverman, Yue Shen, Marta Volonteri, Knud Jahnke | Summary: JWST is revealing a new remarkable population of high-redshift ($zgtrsim4$), low-luminosity Active Galactic Nuclei (AGNs) in deep surveys and detecting the host galaxy stellar light in the most luminous and massive quasars at […]

Controllable suppression of the unconventional superconductivity in bulk and thin-film Sr$_{2}$RuO$_{4}$ via high-energy electron irradiation

Posted by dbos February 29, 2024March 11, 2024Cornell

Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Jacob P. Ruf, Hilary M. L. Noad, Romain Grasset, Ludi Miao, Elina Zhakina | Summary: In bulk Sr$_{2}$RuO$_{4}$, the strong sensitivity of the superconducting transition temperature $T_{text{c}}$ to nonmagnetic impurities provides robust evidence for a superconducting order parameter that changes sign around the Fermi surface. In […]

SeD: Semantic-Aware Discriminator for Image Super-Resolution

Posted by dbos February 29, 2024Peking

Kavli Affiliate: Li Xin Li | First 5 Authors: Bingchen Li, Xin Li, Hanxin Zhu, Yeying Jin, Ruoyu Feng | Summary: Generative Adversarial Networks (GANs) have been widely used to recover vivid textures in image super-resolution (SR) tasks. In particular, one discriminator is utilized to enable the SR network to learn the distribution of real-world […]

Signatures of Majorana protection in a three-site Kitaev chain

Posted by dbos February 29, 2024March 11, 2024Delft

Kavli Affiliate: Michael Wimmer | First 5 Authors: Alberto Bordin, Chun-Xiao Liu, Tom Dvir, Francesco Zatelli, Sebastiaan L. D. ten Haaf | Summary: Majorana zero modes (MZMs) are non-Abelian excitations predicted to emerge at the edges of topological superconductors. One proposal for realizing a topological superconductor in one dimension involves a chain of spinless fermions, […]

Distal tuft dendrites shape and maintain new place fields

Posted by dbos February 28, 2024March 11, 2024Columbia

Kavli Affiliate: Franck Polleux Attila Losonczy | Authors: Justin K. O’Hare, Jamie Wang, Margjele D. Shala, Franck Polleux and Attila Losonczy | Summary: Hippocampal pyramidal neurons support episodic memory by integrating complementary information streams into new ‘place fields’. Distal tuft dendrites are thought to initiate place field formation via plateau potentials. However, the hitherto experimental […]

A 2D Gabor-wavelet baseline model out-performs a 3D surface model in scene-responsive cortex

Posted by dbos February 28, 2024March 11, 2024UCSD / Salk

Kavli Affiliate: John Serences | Authors: Anna Shafer-Skelton, Timothy F Brady and John T Serences | Summary: Understanding 3D representations of spatial information, particularly in naturalistic scenes, remains a significant challenge in vision science. This is largely because of conceptual difficulties in disentangling higher-level 3D information from co-occurring features and cues (e.g., the 3D shape […]

Small and Large Dust Cavities in Disks around mid-M Stars in Taurus

Posted by dbos February 28, 2024March 11, 2024Peking

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Yangfan Shi, Feng Long, Gregory J. Herczeg, Daniel Harsono, Yao Liu | Summary: High-angular resolution imaging by ALMA has revealed the near-universality and diversity of substructures in protoplanetary disks. However, disks around M-type pre-main-sequence stars are still poorly sampled, despite the prevalence of M-dwarfs in the […]
