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.

Dynamic Modeling of Crew Performance for Long-Duration Space Missions [PDF]

open access: yes, 2005
Crew time is one of the most valuable and limited resources during long-duration space missions. Crew time requirements fluctuate depending on variations in crew performance.

Finding excesses in model parameter space

open access: yesEuropean Physical Journal C: Particles and Fields
Simulation-based inference (SBI) makes it possible to infer the parameters of a model from high-dimensional low-level features of the observed events. In this work we show how this method can be used to establish the presence of a weak signal on top of ...

Model‐Space Localization in Serial Ensemble Filters

open access: yesJournal of Advances in Modeling Earth Systems, 2019
Ensemble‐based data assimilation systems typically use covariance localization to dampen spurious correlations associated with sampling error while increasing the rank of the covariance estimate. Variational methods use model‐space localization, in which

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Theoretical growth model space for Cities [PDF]

open access: yes, 2012
This work raises a theoretical model of spatial growth for the cities in which makes explicit that the growth of population and income growth determined the city s expansion in terms of area built for business and the area destined for housing At the ...

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Model for Assessment of Public Space Quality in Town Centers [PDF]

open access: yes, 2016
Public space is an important element of urban structure, playing various spatial, social and economic roles in towns/cities. Its quality influences the quality of life of the inhabitants and the attractiveness of the town as a whole. Public space located
