Complex History of Organellar Introgression in Nothofagus Trees: Chloroplast and Mitochondrial Capture Facilitated by Natural Selection

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Map of sampling for each species, chloroplast and mitochondrial genome phylogeny. ABSTRACT Hybridization is widespread across diverse groups of organisms, and in some cases, organellar genomes of one species become fixed in another following hybridization and backcrossing, a phenomenon known as organelle capture.

GM-PHD filter multi-target tracking in sonar images

open access: yes, 2006
The Gaussian Mixure Probability Hypothesis Density (GM-PHD) Multi-target Tracker was developed as an extension to the GM-PHD filter to provide track continuity. The algorithm is demonstrated on forward-looking sonar data with clutter and is compared with

A Gaussian Mixture CPHD Filter for Multi-Target Tracking in Target-Dependent False Alarms

open access: yesRemote Sensing
The estimation of the target number and individual tracks are two major tasks in multi-target tracking. The main shortcoming of traditional tracking methods is the cumbersome data association between measurements and targets. The cardinalized probability

Stability and cooperativity in chimeric de novo TIM barrels via quarter swapping

open access: yesProtein Science, Volume 35, Issue 6, June 2026.
Abstract The use of repetitive units as building blocks in protein design, mimicking evolutionary duplication events, is a valuable strategy that reduces structural complexity. Such modular designs offer an opportunity to dissect how local contributions are integrated in a context‐dependent manner.

Group target tracking with the gaussian mixture probability hypothesis density filter

open access: yes, 2007
The Probability Hypothesis Density (PHD) filter was originally devised to address non-conventional tracking problems such as group target processing, tracking in high target density, tracking closely spaced targets and detecting targets of interest in a ...

Data association for the PHD filter

open access: yes, 2005
The Probability Hypothesis Density (PHD) filter was developed as a suboptimal method for tracking a time varying number of targets. The first order statistical moment of the multiple target posterior distribution, called the Probability Hypothesis ...

Genetic control of wheat flour end‐use quality and rheology by genome‐wide association studies

open access: yesThe Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Improving end‐use quality in bread wheat (Triticum aestivum) requires dissecting the genetic basis of complex processing traits and deploying robust prediction pipelines in breeding. We performed genome‐wide association studies (GWASs) using 1767 high‐quality single‐nucleotide polymorphisms generated by genotyping‐by‐sequencing in a diverse ...

Probability hypothesis density filter with adaptive parameter estimation for tracking multiple maneuvering targets

open access: yes, 2016
The probability hypothesis density (PHD) filter has been recognized as a promising technique for tracking an unknown number of targets. The performance of the PHD filter, however, is sensitive to the available knowledge on model parameters such as the ...

Prevalence and Spatial Distribution of Chronic Respiratory Diseases in Dar es Salaam, Tanzania: Hydrological and Household Influences

open access: yesGeoHealth, Volume 10, Issue 6, June 2026.
Abstract Chronic Respiratory Diseases (CRDs) are a major global health burden, causing significant mortality and morbidity. The World Health Organization reports CRDs led to 4.1 million deaths in 2023, affecting 454.6 million people (5.54% globally). While tobacco smoking is the leading risk factor, others include air pollution, occupational hazards ...

A multiple model probability hypothesis density tracker for time-lapse cell microscopy sequences [PDF]

open access: yes, 2020
. Quantitative analysis of the dynamics of tiny cellular and subcellular structures in time-lapse cell microscopy sequences requires the development of a reliable multi-target tracking method capable of tracking numerous similar targets in the presence ...
