High-Temperature and High-Speed Atomic Force Microscopy Using a qPlus Sensor in Liquid via Quadpod Scanner and Hybrid-Loop Frequency Demodulation
arXiv:2604.04970v2 Announce Type: replace Abstract: Atomic-resolution imaging on molten metal/solid interfaces at temperatures above 200 {\deg}C was achieved using a high-temperature, high-speed atomic force microscope (AFM) equipped with a qPlus sensor. A tip-scanning high-speed Quadpod scanner for a large mass load of qPlus sensor (2.3 g) was developed to enhance thermal drift tolerance by high-speed scanning and thermal insulation from the heated specimen. This scanner has dominant...
Russian drug suspects arrested in Bali after high-speed car chase
Russian drug suspects arrested in Bali after high-speed car chase Indonesia has some of the world's toughest anti-drug laws, including the death penalty for traffickers, but has maintained a moratorium on executions for several years. Indonesian authorities arrested two Russian nationals suspected of smuggling drugs into Bali after a high-speed car chase on the popular resort island, an official said on Sunday (Jun 7). The woman, 52, and the 40-year-old man were arrested after trying to...
Miracle baby survives being thrown from car in rollover crash following high speed chase
Independent TV Showing now | News 01:56 Miracle baby survives being thrown from car in rollover crash following high speed chase A baby miraculously survived after it was thrown from a car during a high-speed police chase. On 24 May, an Arkansas State Police officer unsuccessfully attempted to stop a 2012 Toyota Highlander for a ticket violation, with a pursuit beginning shortly after. Following a lengthy chase at speeds over 100mph, the SUV, which had four children inside, struck a pole and...
Towards Neuromorphic Event-Based Sensing for High-Speed Multi-Spectral Classification and Tracking of Microparticles
arXiv:2605.31038v1 Announce Type: new Abstract: Conventional image-based microfluidic systems face an inherent trade-off between throughput, imaging speed, and data bandwidth, limiting their ability to monitor high-velocity flows without significant motion blur or prohibitive data generation. Event-based sensing has emerged as a high-speed, low-power alternative, but has so far been largely restricted to tracking monodisperse, spherical particles.
HUNT: High-Speed UAV Navigation and Tracking in Unstructured Environments via Instantaneous Relative Frames
arXiv:2509.19452v4 Announce Type: replace Abstract: Search and rescue operations require unmanned aerial vehicles to both traverse unknown unstructured environments at high speed and track targets once detected. Achieving both capabilities under degraded sensing and without global localization remains an open challenge. Recent works on relative navigation have shown robust tracking by anchoring planning and control to a visible detected object, but cannot address navigation when no target is...
MARUT: An Exascale-Ready, GPU-Accelerated High-Order CFD Framework with AMR for High-Speed Flows and Finite-Rate Chemistry
arXiv:2605.26388v3 Announce Type: replace Abstract: We present MARUT, a scalable multi-GPU computational fluid dynamics (CFD) framework designed for high-fidelity simulations of compressible flows spanning subsonic to hypersonic regimes, including chemically reacting nonequilibrium flows with finite-rate chemistry and adaptive mesh refinement (AMR). The framework addresses a central challenge in contemporary scientific computing: the development of numerically accurate and computationally...

High-Speed Multi-Dimensional Optical Field Measurement via MMF-MCF Spatial-Temporal Mapping Architecture
arXiv:2606.06841v1 Announce Type: new Abstract: Wavelength and state of polarization constitute fundamental dimensions of optical fields. While simultaneous quantification of these parameters is critical, existing methodologies often lack the speed required for real-time analysis. Here, we present a compact high-dimensional optical field analyzer employing a discrete spatiotemporal sampling architecture based on multimode and multicore fibers.
High-speed mid-infrared single-photon upconversion spectrometer
arXiv:2605.30701v1 Announce Type: new Abstract: Sensitive and fast mid-infrared (MIR) spectroscopy is highly attractive in a variety of applications including astronomical observation, pharmaceutical synthesis, and environmental monitoring. However, the performance of conventional MIR spectrometers has long been hindered by the limited sensitivity of narrow-bandgap detectors and/or the deficient brightness of broadband light sources. Here, we devise and implement an ultra-sensitive and...
Tracking multi-site somatic voltage dynamics via high-speed fiber photometry
Investigating neural circuit dynamics across distributed brain regions in awake, behaving animals is crucial for understanding complex behavior. Genetically encoded voltage indicators (GEVIs) offer a powerful approach to tracking transmembrane voltage with high temporal and cellular specificity. However, scaling high-sensitivity GEVI recordings across multiple brain regions and multiple animals simultaneously remains a major technical challenge.
