Video Tracking Using Dual-Tree Wavelet Polar Matching and Rao-Blackwellised Particle Filter

open access: yesEURASIP Journal on Advances in Signal Processing, 2009
We describe a video tracking application using the dual-tree Polar Matching Algorithm. We develop the dynamical and observation models in a probabilistic setting and study the empirical probability distribution of the Polar Matching output.

Partial Likelihood and Estimating Equations

open access: yes, 1997
Consider a regression model for discrete-time stochastic processes, with a (partially specified) model for the conditional distribution of the response given the covariate and the past observations. Suppose we also have some knowledge about how the parameter of interest affects the conditional distribution of the covariate given the past.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

A robust partial least squares method with applications [PDF]

open access: yes, 2007
Partial least squares regression (PLS) is a linear regression technique developed to relate many regressors to one or several response variables. Robust methods are introduced to reduce or remove the effect of outlying data points.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

open access: yesFEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Imaging response to immune checkpoint inhibitors in patients with advanced melanoma: a retrospective observational cohort study

open access: yesFrontiers in Oncology
BackgroundThe association between objective imaging response and first line immune checkpoint inhibitor (ICI) therapy regimes in advanced melanoma remains uncharacterized in routine practice.MethodsWe conducted a multi-center retrospective cohort ...

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Uncertainty analysis based on Bayesian inference for partial defect verification of PWR spent nuclear fuel

open access: yesNuclear Engineering and Technology
Ensuring the integrity of spent nuclear fuel (SNF) is essential for nuclear non-proliferation efforts. While detecting gross defects is relatively straightforward, identifying partial defects remain challenging.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Analysis of the nearly complete mitochondrial genome of Paederus fuscipes (Coleoptera: Staphylinidae)

open access: yesMitochondrial DNA. Part B. Resources, 2018
The nearly complete mitochondrial genome of Paederus fuscipes (GenBank accession no. MG581161) is 17,644 bp in size, containing 13 protein-coding genes, 22 transfer RNAs, two ribosomal RNAs, and a partial control region.
