1H NMR metabolomics and lipidomics analysis of neutrophils reveals biomarkers of ageing, inflammageing and frailty

The FEBS Journal, EarlyView.
Using 1H NMR metabolomics, we measured polar and lipid metabolites from human blood neutrophils from people with frailty (n = 31, mean age 84Y), people with rheumatoid arthritis (n = 16, mean age 55Y), robust older (n = 24, mean age 66Y) and healthy younger people (n = 21, mean age 22Y).

Robust Student’s t Mixture Probability Hypothesis Density Filter for Multi-Target Tracking With Heavy-Tailed Noises

IEEE Access, 2018
In order to improve filtering accuracy and restrain the degradation of filtering performance caused by the heavy-tailed process and measurement noises in multi-target tracking, this paper proposes a robust Student's t mixture probability hypothesis ...

Genetic Determination of Maternal Behaviour in Pigs

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In sows, maternal behaviour is a commercially important trait which affects sow and piglet welfare and the quality and safety of human‐animal interactions, especially if free farrowing of sows without crates is in place. The aim of this study was to evaluate maternal behaviour and to estimate its quantitative genetic parameters in Swiss ...

A PHD-Based Particle Filter for Detecting and Tracking Multiple Weak Targets

IEEE Access, 2019
Joint detection and tracking weak target is a challenging problem whose complexity is intensified when there are multiple targets present at the same time.

Air‐Abrasion With Aluminum Oxide Particles in Non‐Carious Cervical Lesions: Impact on Sclerotic Superficial Layer, Surface Topography, and Restorative Adhesive Performance

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the effect of airborne‐particle abrasion (APA) with aluminum oxide on superficial dentin sclerosis, surface topography, and bonding performance of a universal adhesive in natural non‐carious cervical lesions (NCCLs), using dentin classification by the North Carolina Index (NCI) and Optical Coherence Tomography Index (OCT).

Two Measurement Set Partitioning Algorithms for the Extended Target Probability Hypothesis Density Filter

Sensors, 2019
The extended target probability hypothesis density (ET-PHD) filter cannot work well if the density of measurements varies from target to target, which is based on the measurement set partitioning algorithms employing the Mahalanobis distance between ...

Leaders' Functional Specialization and Responses to Institutional Shifts during Crises: Evidence from the Pandemic

Journal of Management Studies, EarlyView.
Abstract Prior studies on crisis management often highlight the adaptiveness of generalist leaders, whose diverse functional experiences allow for flexible and innovative responses. However, we propose that in situations where crises lead to abrupt shifts in dominant institutional pressures, leaders with specialized functional backgrounds potentially ...

Smooth Variable Structure Filter in Random Finite Set Applications

IEEE Access
Data association and filter robustness are two key problems for general multiple target tracking. Classic data association methods have high computational complexity, and the gold standard Kalman Filter (KF) suffers when the motion model does not match ...

Joint Tracking and Classification of Extended Targets Using Random Matrix and Bernoulli Filter for Time-Varying Scenarios

IEEE Access, 2019
In surveillance applications, the extent states and measurements of extended targets received by sensors are time-varying. In this paper, we propose a joint tracking and classification (JTC) method for single extended target under the presence of clutter
