Cooperative Localization for Multi-AUVs Based on GM-PHD Filters and Information Entropy Theory
Sensors, 2017 Cooperative localization (CL) is considered a promising method for underwater localization with respect to multiple autonomous underwater vehicles (multi-AUVs).

State Estimation and Smoothing for the Probability Hypothesis Density Filter
, 2010 Tracking multiple objects is a challenging problem for an automated system, with applications in many domains. Typically the system must be able to represent the posterior distribution of the state of the targets, using a recursive algorithm that takes ...

Ecography, EarlyView.Species distribution models are key to evaluate how climate change threatens European forests and tree species distributions. However, current models struggle to integrate ecophysiological processes. Mechanistic models are complex and have high parameter requirements.

The FEBS Journal, EarlyView.Investigated mutations in transthyretin (TTR) disrupt the F87‐centered hydrophobic core that stabilizes its tetrameric structure. The mild I107V mutation weakens inter‐chain packing, while H88R fully abolishes tetramer formation, yielding a monomeric, aggregation‐prone form. Structural, biophysical, and computational analyses reveal that both mutations

Tracking Ground Targets with a Road Constraint Using a GMPHD Filter
Sensors, 2018 The Gaussian mixture probability hypothesis density (GMPHD) filter is applied to the problem of tracking ground moving targets in clutter due to its excellent multitarget tracking performance, such as avoiding measurement-to-track association, and its ...

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).

IPDA filters in the sense of Gaussian mixture PHD algorithm [PDF]
Scientific Technical Review, 2016 The Integrated Probabilistic Data Association (IPDA) type filters provide estimates of the underlying target probability of existence as well as they track state maintenance. For each scan, IPDA recursive calculates the probability of target existence in

Ibis, EarlyView.Non‐native species are one of the greatest threats to biodiversity worldwide due to their direct and indirect effects on native communities. There are two opposing hypotheses to explain how non‐native species successfully establish outside their native range.

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 ...

Extended Target Tracking with a Cardinalized Probability Hypothesis Density Filter
, 2011 This paper presents a cardinalized probability hypothesis density (CPHD) filter for extended targets that can result in multiple measurements at each scan.
