Identifying molecules as biosignatures with assembly theory and mass spectrometry

SM Marshall, C Mathis, E Carrick, G Keenan… - Nature …, 2021 - nature.com
The search for alien life is hard because we do not know what signatures are unique to life.
We show why complex molecules found in high abundance are universal biosignatures and …

Molecular assembly indices of mineral heteropolyanions: some abiotic molecules are as complex as large biomolecules

RM Hazen, PC Burns, HJ Cleaves… - Journal of the …, 2024 - royalsocietypublishing.org
Molecular assembly indices, which measure the number of unique sequential steps
theoretically required to construct a three-dimensional molecule from its constituent atomic …

Defending and integrating an organism by the immune system

Z Dembic - Scandinavian Journal of Immunology, 2022 - Wiley Online Library
The Integrity model proposes that the adaptive immune response defends, protects and
keeps vigilance over the unity of an organism. These functions conceptually rely on three …

Ladderpath approach: how tinkering and reuse increase complexity and information

Y Liu, Z Di, P Gerlee - Entropy, 2022 - mdpi.com
The notion of information and complexity are important concepts in many scientific fields
such as molecular biology, evolutionary theory and exobiology. Many measures of these …

A universal chemical constructor to explore the nature and origin of life

GJT Cooper, SI Walker, L Cronin - … Models for the Origin of Life, 2023 - Wiley Online Library
In this chapter, we discuss the conceptual developments needed to take a new look at the
nature of life, the origin of life, and how chemical systems can transition to evolutionary …

Minimum description length clustering to measure meaningful image complexity

L Mahon, T Lukasiewicz - arXiv preprint arXiv:2306.14937, 2023 - arxiv.org
Existing image complexity metrics cannot distinguish meaningful content from noise. This
means that white noise images, which contain no meaningful information, are judged as …

Graph-Based Mutations for Music Generation

M Kanani, S O'Leary, J McDermott - Proceedings of the Companion …, 2023 - dl.acm.org
Our study aims to compare the effects of direct mutation and graph-based mutation on
representations of music domain. We focus on short tunes from the Irish folk tradition …

[HTML][HTML] Minimum description length clustering to measure meaningful image complexity

L Mahon, T Lukasiewicz - Pattern Recognition, 2024 - Elsevier
We present a new image complexity metric. Existing complexity metrics cannot distinguish
meaningful content from noise, and give a high score to white noise images, which contain …

Dynamics of one-dimensional spin models under the line-graph operator

MA Javarone, JA O'Connor - Proceedings of the …, 2021 - royalsocietypublishing.org
We investigate the application of the line-graph operator to one-dimensional spin models
with periodic boundary conditions. The spins (or interactions) in the original spin structure …

Phase transition of parallelizability in assembly systems

I Kobayashi, S Sasa - Physical Review Research, 2023 - APS
We propose a phase transition on the feasibility of efficient parallel assembly. By introducing
the parallel efficiency that measures how efficiently the parallel assembly works, the …
