Metallic Ultrasound Waveguides as a Distributed Tactile Sensing Platform for Contact Localization, Force Estimation, and Material Class Discrimination

Posted by klaurent July 2, 2026Caltech

Kavli Affiliate: Morteza Gharib| Summary:Tactile sensing is central to how robotic systems interact with the real world, yet current solutions face a tradeoff between sensing area and system complexity. This work investigates metallic ultrasound waveguides as distributed tactile sensors fully interrogated from a single proximal transducer. Using cylindrical indenters, we characterized the acoustic response to […]

Tracing the Boundary of the South Atlantic Anomaly Region with SPHEREx Transient Flagging Rates

Posted by klaurent July 2, 2026Caltech

Kavli Affiliate: James Bock | Summary:The NASA SPHEREx satellite was launched in 03/2025 to survey the full sky between 0.75 – 5.0 um. The image processing of SPHEREx H2RG detectors includes real-time flagging of transient events during integration. SPHEREx follows a polar orbit passing over the South Atlantic Anomaly (SAA) zone multiple times daily, where […]

Coupling loss and transmission in a multimode fiber-fed Virtually Imaged Phased Array (VIPA)

Posted by klaurent July 2, 2026Harvard

Kavli Affiliate: David Charbonneau | Summary:The Virtually Imaged Phased Array (VIPA) is a spectral disperser that has seen increasing adoption across various applications, including optical telecommunications, high-resolution spectroscopy, and LiDAR. Although VIPAs are typically fed by single-mode optical fiber in these applications, there is growing interest in using a multimode optical fiber feed to enable […]

Satellite quenching by radio jets of central galaxies in galaxy groups

Posted by klaurent July 2, 2026Peking

Kavli Affiliate: Yingjie Peng | Summary:Feedback from active galactic nuclei (AGN) is now recognized as a key component of galaxy formation models. It plays a central role in regulating the growth and quenching of galaxies in the center of groups. However, the impact of AGN feedback from central galaxies on satellite galaxies remains largely unexplored. […]

Time-Dependent Integrability from Gauge Theory, I

Posted by klaurent July 2, 2026Tokyo

Kavli Affiliate: Masahito Yamazaki | Summary:Solvable time-dependent systems provide important settings for studying non-equilibrium physics, where exact results are rare. They are also useful for benchmarking quantum simulations, which can directly probe real-time dynamics beyond the reach of conventional numerical approaches. In this paper, we show that the four-dimensional Chern-Simons theory offers a natural and […]

Clinical Relevant Immunosuppressive Drugs Differentially Modulate Axonal Outgrowth from Human Stem Cell Derived Neurons

Posted by dbos July 2, 2026July 13, 2026UCSD / Salk

Kavli Affiliate: Mark H. Tuszynski | Authors: Gunnar H.D. Poplawski, Chase Weinholtz, Grace Woodruff, Ruhel Ahmad, Wyatt Bunner, Rodrigo Gonzales and Mark H. Tuszynski | Summary: Neural stem cell (NSC) transplantation is a promising strategy for repairing the injured spinal cord, but transplanted cells typically require immunosuppressive therapy to prevent rejection—even for induced pluripotent stem […]

Uncovering internal states with a robust shared-state multi-neuron GLM-HMM framework

Posted by dbos July 2, 2026July 13, 2026Hopkins

Kavli Affiliate: Adam S. Charles and Patricia Janak | Authors: Aamna Lawrence, Eva Yezerets, Patricia H Janak and Adam Charles | Summary: Neural systems exhibit multiple firing states that reflect an organism’s internal state and modulate the relationship between external environmental stimuli and behavior. Several studies have inferred these latent states by supplementing the traditional […]

One More Time: Revisiting Neural Quantum States from a Reinforcement Learning Perspective

Posted by klaurent July 2, 2026July 13, 2026Delft

Kavli Affiliate: Eliska Greplova | Summary:Neural quantum states (NQS) provide a flexible and scalable framework for approximating quantum many-body wavefunctions. Among NQS parameterizations, autoregressive models are especially attractive because they enable exact, independent sampling from the Born distribution, avoiding the autocorrelation and mixing issues of Markov chain methods. Yet their optimization remains comparatively underexplored: Adam […]

Pulsar Backend for 21 CentiMeter Array: Implementation of Data Acquisition and Initial Results

Posted by klaurent July 2, 2026July 13, 2026Peking

Kavli Affiliate: Kejia Lee | Summary:We implemented a data acquisition system for 21 CentiMeter Array (21CMA), enabling baseband observations targeting pulsars and fast radio bursts. Based on the Radio Frequency System-on-Chip (RFSoC) platform, the new backend is capable of instantaneously covering the effective bandwidth from 50 to 350 MHz, with multi-board synchronization achieved at the […]
