Noise Modeling and Calibration of a Two-Stage Cryogenic Charge Amplifier for the SPLENDOR Experiment

Posted by klaurent October 1, 2025Stanford

Kavli Affiliate: Noah Kurinsky | Summary:The SPLENDOR Collaboration studies novel narrow-gap semiconductors and engineered a substrate agnostic detector platform to achieve $mathcalO$(meV) energy sensitivity designed for low mass dark matter searches. This was achieved using low-capacitance and low-noise commercial CryoHEMTs in a split-stage topology integrated throughout a dilution refrigerator. Designed with a source-follower HEMT at […]

Flexible gaze reinstatement during working memory for natural scenes

Posted by dbos October 1, 2025October 13, 2025UCSD / Salk

Kavli Affiliate: Anastasia Kiyonaga | Authors: Yueying Dong, Yunchen Hung, Lana Gaspariani and Anastasia Kiyonaga | Summary: Working memory (WM) representations may be more action-oriented and anatomically widespread than previously assumed. For instance, oculomotor signatures like gaze biases can reflect spatial WM content. However, the specificity and functional relevance of such signatures is unclear. Here, […]

From Maps to Models: A Survey on the Reliability of Small Studies of Task-Based fMRI

Posted by dbos October 1, 2025October 13, 2025Hopkins

Kavli Affiliate: Martin Lindquist | Authors: Patrick Sadil and Martin A. Lindquist | Summary: Task-based functional magnetic resonance imaging (fMRI) is a powerful tool for studying brain function. However, the reliability and viability of small-sample studies remain a concern. While it is well understood that larger samples are preferable, researchers often need to interpret findings […]

Multiscale Hyperbolic Embedding for Cell Hierarchies in Large-Scale Bioinformatics Data

Posted by dbos October 1, 2025October 13, 2025UCSD / Salk

Kavli Affiliate: Tatyana Sharpee | Authors: Mingchen Yao, Anoop Praturu and Tatyana Sharpee | Summary: The increasing size of datasets poses challenges for their visualization and interpretation, highlighting the need for scalable and effective analysis methods. Hyperbolic embedding have shown strong potential in capturing complex hierarchical structures across diverse systems. However, existing hyperbolic embedding methods […]

Simulating Spectral Confusion in SPHEREx Photometry and Redshifts

Posted by klaurent October 1, 2025Caltech

Kavli Affiliate: James Bock | Summary:We model the impact of source confusion on photometry and the resulting spectrophotometric redshifts for SPHEREx, a NASA Medium-Class Explorer that is carrying out an all-sky near-infrared spectral survey. Spectral confusion from untargeted background galaxies degrades sensitivity and introduces a spectral bias. Using interpolated spectral energy distributions (SEDs) from the […]

Accelerated Tempo of Cortical Neurogenesis in Down Syndrome

Posted by dbos October 1, 2025October 13, 2025UCSF

Kavli Affiliate: Alex Pollen | Authors: Jingwen W Ding, Chang N Kim, Marilyn R Steyert, Andrew T Yuan, David Shin, Dimitar Ivanov, Tomasz J. Nowakowski and Alex Aaron Pollen | Summary: Down syndrome (DS), caused by trisomy 21 (TS21), is the most common genetic cause of intellectual disability1,2. The neurological impacts of DS first manifest […]
