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.

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.

Feasibility Study For Hydrogen Producing Colony on Mars [PDF]
arXiv, 2021 A technologically mature colony on Mars can produce and deliver at least 1 million tons of liquid hydrogen per year to one or more propellant depots at Low Earth Orbit (LEO). Production of 1 $kg$ of hydrogen at Marian colony and its delivery to LEO requires an energy expenditure of 1.4 $GJ$ on Mars.

Reaction-diffusion model for pattern formation in E. coli swarming colonies with slime [PDF]
Phys. Rev. E. 71, 31908 (2005), 2005 A new experimental colonial pattern and pattern transition observed in E. coli MG1655 swarming cells grown on semi-solid agar are described. We present a reaction-diffusion model that, taking into account the slime generated by these cells and its influence on the bacterial differentiation and motion, reproduces the pattern and successfully predicts ...

Plan for Building a 1000 Person Martian Colony [PDF]
arXiv, 2021 The implementation of a feasible colony on Mars has been discussed and analyzed for some time. It is noted that Mars offers all necessary in-situ resources to allow for self-sustainability, with the most efficient techniques and systems to produce water, food, metals, plastics, and other materials to be discussed.

Decolonial AI Alignment: Openness, Viśe\d{s}a-Dharma, and Including Excluded Knowledges [PDF]
arXiv, 2023 Prior work has explicated the coloniality of artificial intelligence (AI) development and deployment through mechanisms such as extractivism, automation, sociological essentialism, surveillance, and containment. However, that work has not engaged much with alignment: teaching behaviors to a large language model (LLM) in line with desired values, and ...
