Spatial navigation—a unique window into physiological and pathological aging
Frontiers in Aging Neuroscience, 2012 Spatial navigation is a skill of determining and maintaining a trajectory from one place to another. Mild progressive decline of spatial navigation develops gradually during the course of physiological ageing.

Spatial navigation in young versus older adults
Frontiers in Aging Neuroscience, 2013 Older age is associated with changes in the brain, including the medial temporal lobe, which may result in mild spatial navigation deficits, especially in allocentric navigation.

Visual Navigation with Spatial Attention [PDF]
2021 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2021 This work focuses on object goal visual navigation, aiming at finding the location of an object from a given class, where in each step the agent is provided with an egocentric RGB image of the scene. We propose to learn the agent's policy using a reinforcement learning algorithm.

A synaptic signal for novelty processing in the hippocampus
Nature Communications, 2022 Memory formation and recall are complementary processes within the hippocampus. Here the authors demonstrate a synaptic signal of novelty in the hippocampus and provide a computational framework for how such a novelty-driven switch may enable flexible ...

Research on Remote GPS Common-View Precise Time Transfer Based on Different Ionosphere Disturbances
Sensors, 2020 Propagation path delays are a major error for the remote precise time transfer of common view; these path delays contain the ionosphere and troposphere impact, while the contributions of the ionosphere and the troposphere from common-view satellites to ...

Thermal Infrared Spectral Characteristics of Bunker Fuel Oil to Determine Oil-Film Thickness and API
Journal of Marine Science and Engineering, 2020 Remote sensing is an important method for monitoring marine oil-spill accidents. However, methods for measuring oil-film thickness remain insufficient. Due to the stable differences in the surface emissivity and temperature of oil and water, the oil film

Free Choice Navigation in the Real World: Giving Back Freedom to Wayfinders
ISPRS International Journal of Geo-Information, 2023 In recent years, there has been collected evidence suggesting that increased usage of navigation assistance systems has a harmful effect on spatial cognition, including spatial knowledge acquisition. Previously, we proposed a potential remedy called Free
