Laser ablated sub-wavelength structure anti-reflection coating on an alumina lens

Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Shaul Hanany, Scott Cray, Samuel Dietterich, Jan Dusing, Calvin Firth | Summary: We used laser ablation to fabricate sub-wavelength structure anti-reflection coating (SWS-ARC) on a 5 cm diameter alumina lens. With an aspect ratio of 2.5, the SWS-ARC are designed to give a broad-band low reflectance response […]

Clover-like object vector representations support human spatial cognition

Kavli Affiliate: Jonathan Whitlock | Authors: Marcia Becu, Ivan Markel Krasovec, Pearl Saldanha, Jonathan Whitlock and Christian F Doeller | Summary: Vector-based spatial coding has been demonstrated in rodents, yet its neural basis in humans and its contribution to navigation remain poorly understood. Using a novel spatial updating task, we show that egocentric directional signals […]

Image Corruption-Inspired Membership Inference Attacks against Large Vision-Language Models

Kavli Affiliate: Xiang Zhang | First 5 Authors: Zongyu Wu, Minhua Lin, Zhiwei Zhang, Fali Wang, Xianren Zhang | Summary: Large vision-language models (LVLMs) have demonstrated outstanding performance in many downstream tasks. However, LVLMs are trained on large-scale datasets, which can pose privacy risks if training images contain sensitive information. Therefore, it is important to […]

Correcting impedance measurements for background parasitics to characterize circuit components in cryogenic environments

Kavli Affiliate: Noah A. Kurinsky | First 5 Authors: Riley J. Carpenter, Jadyn Anczarski, Ivar Rydstrom, Aviv Simchony, Zoe J. Smith | Summary: Predictable circuit response is a critical prerequisite for accurate electronic measurements. We describe a powerful, yet straightforward, experimental method and analysis model that utilizes an affordable LCR meter in conjunction with an […]

A big red dot at cosmic noon

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Federica Loiacono, Roberto Gilli, Marco Mignoli, Giovanni Mazzolari, Roberto Decarli | Summary: We report the discovery of a little red dot (LRD), dubbed BiRD (‘big red dot’), at $z=2.33$ in the field around the $z=6.3$ quasar SDSSJ1030+0524. Using NIRCam images, we identified it as a bright outlier […]

Spot-Crossing Variations Confirm a Misaligned Orbit for a Planet Transiting an M Dwarf

Kavli Affiliate: Avi Shporer | First 5 Authors: Patrick Tamburo, Samuel W. Yee, Juliana García-Mejía, David Charbonneau, Allyson Bieryla | Summary: TOI-3884~b is an unusual 6.4~R$_oplus$ planet orbiting an M4 host, whose transits display large and persistent spot-crossing events. We used the textit{Tierras} Observatory to monitor both the long-term photometric variability of TOI-3884 and changes […]
