Collective colony growth is optimized by branching pattern formation in Pseudomonas aeruginosa
Molecular Systems Biology, 2021 Branching pattern formation is common in many microbes. Extensive studies have focused on addressing how such patterns emerge from local cell–cell and cell–environment interactions. However, little is known about whether and to what extent these patterns

A Material Lens on Coloniality in NLP [PDF]
arXiv, 2023 Coloniality, the continuation of colonial harms beyond "official" colonization, has pervasive effects across society and scientific fields. Natural Language Processing (NLP) is no exception to this broad phenomenon. In this work, we argue that coloniality is implicitly embedded in and amplified by NLP data, algorithms, and software.

Large-scale orientational order in bacterial colonies during inward growth [PDF]
eLife 11, e72187 (2022), 2020 During colony growth, complex interactions regulate the bacterial orientation, leading to the formation of large-scale ordered structures, including topological defects and microdomains. These structures may benefit bacterial strains, providing invasive advantages during colonization.

PLoS Biology, 2019 Lifelong infection of the gastric mucosa by Helicobacter pylori can lead to peptic ulcers and gastric cancer. However, how the bacteria maintain chronic colonization in the face of constant mucus and epithelial cell turnover in the stomach is unclear ...

A hierarchical Bayesian approach for estimating the origin of a mixed population [PDF]
IMS Collections 2008, Vol. 3, 237-250, 2008 We propose a hierarchical Bayesian model to estimate the proportional contribution of source populations to a newly founded colony. Samples are derived from the first generation offspring in the colony, but mating may occur preferentially among migrants from the same source population.

Clinical Infectious Diseases, 2018 Background Bacteremia caused by extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae (ESBL-E) is associated with inadequate empirical therapy and substantial mortality in neutropenic patients.

Colony Dynamics and Persistence of Ivory Gull Breeding in Canada
Avian Conservation and Ecology, 2007 Despite the importance of assessing the viability of small and endangered populations, often few demographic data are available. However, when counts are available from discrete sites, a colony- or site-based approach can be useful. We used recent counts

Quantifying metastatic inefficiency:rare genotypes versus rare dynamics [PDF]
, 2014 : We introduce and solve a ‘null model’ of stochastic metastatic colonization. The model is described by a single parameter θ: the ratio of the rate of cell division to the rate of cell death for a disseminated tumour cell in a given secondary tissue ...

Early and dynamic colonization of Central America drives speciation in Neotropical army ants
Molecular Ecology, 2017 The emergence of the Isthmus of Panama is one of the most important events in recent geological history, yet its timing and role in fundamental evolutionary processes remain controversial.

Space colonization. Mars One [PDF]
, 2015 The colonization of Space is the process of creating human settlements beyond the Earth. Theoretically, the colony can be placed: оn the planets, their moons, asteroids; оn the orbits of the celestial bodies; in the Lagrange‘s points. The most popular
