UltraDfeGAN: Detail-Enhancing Generative Adversarial Networks for High-Fidelity Functional Ultrasound Synthesis

Posted by klaurent Peking

Kavli Affiliate: Zhuo Li | First 5 Authors: Zhuo Li, Zhuo Li, , , | Summary: Functional ultrasound (fUS) is a neuroimaging technique known for its high spatiotemporal resolution, enabling non-invasive observation of brain activity through neurovascular coupling. Despite its potential in clinical applications such as neonatal monitoring and intraoperative guidance, the development of fUS […]

Evidence of topological Kondo insulating state in MoTe2/WSe2 moiré bilayers

Posted by klaurent Cornell

Kavli Affiliate: Jie Shan | First 5 Authors: Zhongdong Han, Zhongdong Han, , , | Summary: Topological Kondo insulators (TKIs) are topologically protected insulating states induced not by single-particle band inversions, but by the Kondo interaction between itinerant electrons and a lattice of local magnetic moments. Although experiments have suggested the emergence of three-dimensional (3D) […]

What Sets the Metallicity of Ultra-Faint Dwarfs?

Posted by klaurent Chicago

Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Vance Wheeler, Vance Wheeler, , , | Summary: We use intergalactic medium (IGM) metallicity distributions from several state-of-the-art cosmological simulations of Milky Way analogs and a semi-analytic model of ultra-faint dwarf galaxy (UFD) formation to model the stellar metallicities of UFDs in MW-like environments. We study simulations […]

Ptbp1 is not required for retinal neurogenesis and cell fate specification.

Posted by dbos Hopkins

Kavli Affiliate: Seth Blackshaw | Authors: Haley Appel, Rogger Carmen-Orozco, Clayton Santiago, Thanh Hoang and Seth Blackshaw | Summary: The RNA-binding protein Ptbp1 has been proposed as a master regulator of neuronal fate, repressing neurogenesis through its effects on alternative splicing and miRNA maturation. While prior studies using RNA interference suggested that Ptbp1 loss promotes […]

Bayesian frequency estimation at the fundamental quantum limit

Posted by klaurent MIT

Kavli Affiliate: Lee McCuller | First 5 Authors: James W. Gardner, James W. Gardner, , , | Summary: Searching for a weak signal at an unknown frequency is a canonical task in experiments probing fundamental physics such as gravitational-wave observatories and ultra-light dark matter haloscopes. These state-of-the-art sensors are limited by quantum noise arising from […]
