Machines in a category

open access: yesJournal of Pure and Applied Algebra, 1980
AbstractAfter a brief historical review of early attempts to apply category theory to place sequential machines and control systems in a unified framework, we present three contributions to the theory of machines in a category: the dynamical interpretation functor which relates the response of a machine to a sequence of inputs with the reachability map

The epithelial barrier theory proposes a comprehensive explanation for the origins of allergic and other chronic noncommunicable diseases

open access: yesFEBS Letters, EarlyView.
Exposure to common noxious agents (1), including allergens, pollutants, and micro‐nanoplastics, can cause epithelial barrier damage (2) in our body's protective linings. This may trigger an immune response to our microbiome (3). The epithelial barrier theory explains how this process can lead to chronic noncommunicable diseases (4) affecting organs ...
