Fatigue‐Resistant Mechanoresponsive Color‐Changing Hydrogels for Vision‐Based Tactile Robots

Advanced Materials, Volume 37, Issue 49, December 10, 2025.
Mechanoresponsive color‐changing materials that can reversibly and resiliently change color in response to stress are highly desirable for diverse technologies in optics, sensors, and robots; however, such materials are rarely achieved. This work reports a fatigue‐resistant mechanoresponsive color‐changing hydrogel that exhibits reversible, resilient ...

Learning Depth from Monocular Videos using Direct Methods

, 2017
The ability to predict depth from a single image - using recent advances in CNNs - is of increasing interest to the vision community. Unsupervised strategies to learning are particularly appealing as they can utilize much larger and varied monocular ...

Image‐Based Estimation of Porosity and Tortuosity in Fibrous Acoustic Absorbers

Engineering Reports, Volume 7, Issue 12, December 2025.
A rapid, non‐destructive workflow estimates porosity and tortuosity in fibrous acoustic materials from simple micrographs. Using image segmentation and geometric descriptors, the method achieves sub‐0.3% porosity error and consistent tortuosity ranking, enabling fast material screening and inline quality control without laboratory measurements ...

Stereo R-CNN based 3D Object Detection for Autonomous Driving

, 2019
We propose a 3D object detection method for autonomous driving by fully exploiting the sparse and dense, semantic and geometry information in stereo imagery. Our method, called Stereo R-CNN, extends Faster R-CNN for stereo inputs to simultaneously detect

Nutrient pulse scenarios drive contrasting patterns in the functional stability of freshwater phytoplankton

Limnology and Oceanography, Volume 70, Issue S2, Page S99-S112, December 2025.
Abstract Climate change is increasing the frequency, intensity, and stochasticity of extreme weather events such as heavy rainfall, storm‐induced mixing, or prolonged drought periods. This results in more variable regimes of dissolved nutrients and carbon in lakes and induces temporal fluctuations in the resource availability for plankton communities ...

Spectral Study of Five Major Impact Basins and Their Volcanic Infills on Mercury: A Window Into the Mantle's Properties

Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.
Abstract NASA's MErcury Surface, Space ENvironment, GEochemistry, and Ranging mission has revealed that about 27% of the surface of Mercury is covered by smooth plains, which are mostly volcanic in origin. These plains are mainly located in the northern hemisphere, as well as within and around major impact basins.

From Oxygen to Tellurium: The Impact of the Chalcogen on Nucleophilicities and Basicities of Isochalcogenourea Catalysts

Angewandte Chemie International Edition, Volume 64, Issue 48, November 24, 2025.
Incorporation of different chalcogen atoms allows for the fine‐tuning of nucleophilicity and basicity of commonly used isochalcogenourea organocatalyst scaffolds. Kinetic and thermodynamic descriptors for the molecular properties of the catalysts are introduced as tools to predict their efficiency and tested in acyl transfer and allenoate activation ...

Visual‐Inertial SLAM for Unstructured Outdoor Environments: Benchmarking the Benefits and Computational Costs of Loop Closing

Journal of Field Robotics, Volume 42, Issue 7, Page 3726-3747, October 2025.
ABSTRACT Simultaneous localization and mapping (SLAM) is essential for mobile robotics, enabling autonomous navigation in dynamic, unstructured outdoor environments without relying on external positioning systems. These environments pose significant challenges due to variable lighting, weather conditions, and complex terrain.
