Sacramental Engines: The Trinitarian Ontology of Computers in Charles Babbage’s Analytical Engine

open access: yesReligions, 2022
Charles Babbage’s Analytical Engine can be recollected as a fossilized image of the first digital computer. It is essentially distinguished from all prior and analog computers by the transcription of the ‘mechanical notation’, the separation of the ...

Bioinspired Interfacial Friction Control: From Chemistry to Structures to Mechanics

open access: yesBiomimetics
Organisms in nature have evolved a variety of surfaces with different tribological properties to adapt to the environment. By studying, understanding, and summarizing the friction and lubrication regulation phenomena of typical surfaces in nature ...

Depicting qudit quantum mechanics and mutually unbiased qudit theories

open access: yes, 2014
We generalize the ZX calculus to quantum systems of dimension higher than two. The resulting calculus is sound and universal for quantum mechanics. We define the notion of a mutually unbiased qudit theory and study two particular instances of these ...

A Process Model of Quantum Mechanics

open access: yes, 2014
A process model of quantum mechanics utilizes a combinatorial game to generate a discrete and finite causal space upon which can be defined a self-consistent quantum mechanics.

Mechanisms of Teratogenesis [PDF]

open access: yesAmerican Journal of Anatomy, 1972
Man’s early pictorial and written records make it clear that he was aware of and curious about the structural defects that from birth afflicted some of his fellow men. His attitudes about these congenital variants have ranged widely in different cultures: from romanticizing them in mythology, to using them as portent of coming events, to accepting them

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...
