Investigating transcription factor dynamics in health and disease using FRAP

FEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Visual and Visual‐Inertial SLAM Based on Enhanced Deep Learning Features and Motion Smoothness Constraints

Advanced Intelligent Systems
It is highly challenging to ensure accuracy and robustness of simultaneous localization and mapping (SLAM) algorithms with rapid camera movements and drastic viewpoint changes. In these scenarios, feature extraction, feature matching, and tracking become

Magnetic Maps of Indoor Environments for Precise Localization of Legged and Non-legged Locomotion [PDF]

, 2013
The magnetic field in indoor environments is rich in features and exceptionally easy to sense. In conjunction with any form of odometry, such as wheel- or IMUbased, a map of this field can be used to precisely localize a human or robot in indoor ...

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Tightly-Coupled Monocular Visual-Odometric SLAM Using Wheels and a MEMS Gyroscope

IEEE Access, 2019
In this paper, we present a novel tightly coupled probabilistic monocular visual-odometric simultaneous localization and mapping (VOSLAM) algorithm using wheels and a MEMS gyroscope, which can provide accurate, robust, and long-term localization for ...

Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

FEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

BatSLAM: Simultaneous localization and mapping using biomimetic sonar. [PDF]

PLoS ONE, 2013
We propose to combine a biomimetic navigation model which solves a simultaneous localization and mapping task with a biomimetic sonar mounted on a mobile robot to address two related questions.

Benchmarking of Laser-Based Simultaneous Localization and Mapping Methods in Forest Environments

IEEE Transactions on Geoscience and Remote Sensing
Simultaneous localization and mapping (SLAM) based on laser scanning (LS) has been quickly developed in the last decades. However, the application of LS-SLAM in forest environments is still at an early development stage, limited by the challenges posed ...
