Neuromorphic Optical Tracking and Imaging of Randomly Moving Targets Through Dynamic Dense Scattering Media

open access: yesAdvanced Science, EarlyView.
Vision begins not with images but with change: the retina fires only when something moves, handing the brain a stream of spikes. A neuromorphic imaging system adopts the same strategy—an event sensor that sees like the retina, a spiking network that thinks like the brain—to track and reconstruct fully randomly moving targets through tissue (phantom ...

POI VizNet: New QGIS Tool to construct Visibility Networks in Cities [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Network science and graph theory offer attractive models to describe urban phenomena and examine cases of urban planning and design. However, none of the existing network analysis tools consider simultaneously human visual perception and locations of ...

Synergistic Regulation of Deep‐Cycling‐Induced Zn Pulverization and Resting Galvanic Corrosion in Practical Lean Zinc Anodes

open access: yesAdvanced Science, EarlyView.
Benzotriazole (BTA) regulates Zn reduction kinetics and suppresses galvanic corrosion, simultaneously mitigating Zn pulverization during cycling and self‐corrosion during storage, thereby enabling lean Zn anodes with enhanced cycling stability and extended calendar life.

Plant Metabolites Screening Identifies 7‐epi‐10‐Deacetyltaxol Inhibiting Cell Division by Interfering With the Cell Cycle and Microtubule Organization

open access: yesAdvanced Science, EarlyView.
In this study, an efficient screening system is developed for plant metabolites to find a compound, 7‐epi‐10‐deacetyltaxol, inhibits tissue elongation. It suppresses plant growth through brassinosteroid and microtubule pathways. It is later applied to animal cells and human tumor organoids, resulting in similar cell division suppression. These findings

Experiments on Nonlocal Fluid‐Flow Metamaterials

open access: yesAdvanced Science, EarlyView.
A nonlocal fluid‐flow metamaterial composed of standard microfluidic tubes and connectors is designed. Hence, the current of the system at one position depends on the gradient of fluid flow at many other positions, leading to unusual alternating backward and forward laminar flows of water.

Do We Have Sufficient Knowledge of the Galactic Foreground Emission in Cosmic Microwave Background Science?

open access: yesThe Astrophysical Journal Supplement Series
Galactic foreground emission plays a key role in cosmic microwave background (CMB) science, particularly for detecting primordial gravitational waves. A well-known lesson involves the “dust wave” identified by BICEP2 in 2014, which was ruled out through ...

Assessment of Highway Available Sight Distances Under Disability Glare Using a Field‐of‐View Model and Traffic‐Signboard Recognition

open access: yesIET Intelligent Transport Systems
ABSTRACT Assessing available sight distances (ASDs) affected by disability glare on highways is essential for establishing a relationship among ASDs, sun ray variations, roadside occlusions, and the driver's field‐of‐view. This study proposes a novel disability‐glare‐coupled ASD (DG‐ASD) assessment method for two‐lane highways.

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective

open access: yesAdvanced Electronic Materials, EarlyView.
Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.
