Multimodal sensory overload in dopamine-deficient larval zebrafish leads to paradoxical kinesia

Posted by dbos July 4, 2025July 14, 2025UCSF

Kavli Affiliate: Su Guo | Authors: Krishnashish Bose, Su Guo and Karnika Bhardwaj | Summary: Paradoxical kinesia—the temporary alleviation of motor deficits by powerful, urgent stimuli in Parkinson’s disease (PD)—remains poorly understood at the neural circuit level. Through chemo-genetic ablation of tyrosine hydroxylase-expressing neurons in larval zebrafish and brain-wide calcium imaging under head-fixed, tail-free conditions, […]

An accurate measurement of the spectral resolution of the JWST Near Infrared Spectrograph

Posted by klaurent July 4, 2025Chicago

Kavli Affiliate: Joshua A. Frieman | First 5 Authors: Anowar J. Shajib, Anowar J. Shajib, , , | Summary: The spectral resolution ($R equiv lambda / Delta lambda$) of spectroscopic data is crucial information for accurate kinematic measurements. In this letter, we present a robust measurement of the spectral resolution for the JWST’s Near Infrared […]

Zariski-dense deformations of standard discontinuous groups for pseudo-Riemannian homogeneous spaces

Posted by klaurent July 4, 2025Tokyo

Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: Kazuki Kannaka, Kazuki Kannaka, , , | Summary: Let $X=G/H$ be a homogeneous space of a Lie group $G$. When the isotropy subgroup $H$ is non-compact, a discrete subgroup $Gamma$ may fail to act properly discontinuously on $X$. In this article, we address the following question: in […]

Optimising germanium hole spin qubits with a room-temperature magnet

Posted by klaurent July 4, 2025Delft

Kavli Affiliate: Menno Veldhorst | First 5 Authors: Cecile X. Yu, Cecile X. Yu, , , | Summary: Germanium spin qubits exhibit strong spin-orbit interaction, which allow for high-fidelity qubit control, but also provide a strong dependence on the magnetic field. Superconducting vector magnets are often used to minimize dephasing due to hyperfine interactions and […]

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

Posted by klaurent July 4, 2025Peking

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 July 4, 2025Cornell

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) […]

Enhancing Satellite Quantum Key Distribution with Dual Band Reconfigurable Intelligent Surfaces

Posted by klaurent July 4, 2025Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Muhammad Khalil, Muhammad Khalil, , , | Summary: This paper presents a novel system architecture for hybrid satellite communications, integrating quantum key distribution (QKD) and classical radio frequency (RF) data transmission using a dual-band reconfigurable intelligent surface (RIS). The motivation is to address the growing need for […]
