More Accurate Pose Initialization with Redundant Measurements [PDF]

Proceedings of the 14th International Joint Conference on Computer Vision, Imaging and Computer Graphics Theory and Applications, 2019
The problem described in this paper concerns the problem of initial pose estimation of a non-cooperative target for space applications. We propose to use a Photonic Mixer Device (PMD) sensor in a close range for the visual navigation in order to estimate position and attitude of the space object.

Autophagy and mitophagy in pancreatic β‐cell homeostasis and their involvement in diabetes pathophysiology

FEBS Letters, EarlyView.
This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.

A multi-sensor data fusion algorithm based on consistency preprocessing and adaptive weighting

Automatika
In the data collection of a multi-sensor system, there are problems with large errors, conflicts, and redundancy. To solve the above problem, a multi-sensor data fusion algorithm based on anomaly data preprocessing and adaptive weighted estimation is ...

Translophagy—A potential link between autophagy impairment and translational errors

FEBS Letters, EarlyView.
Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

FEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

When Does Multi-Operator Cellular Redundancy Help V2X? A Cross-Layer Measurement Study

IEEE Open Journal of Vehicular Technology
Multi-operator cellular redundancy is widely proposed for the ultra-reliable, low-latency requirements of vehicle-to-everything (V2X) safety services, increasingly through predictive or learned schedulers.

Robust Dynamic State Estimation Method for Medium Voltage Distribution Networks Based on Improved Adaptive UKF Algorithm

Zhongguo dianli, 2023
To address the issues of the lack of real-time measurement, low accuracy of pseudo measurement, and the assumption of constant system state process noise in existing dynamic state estimation (DSE) methods for medium voltage distribution networks, this ...

Structural and biochemical analysis of a B12 superbinder

FEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.
