A competitive advantage through fast dead matter elimination in confined cellular aggregates

چکیده

Abstract Competition of different species or cell types for limited space is relevant in a variety biological processes such as biofilm development, tissue morphogenesis and tumor growth. Predicting the outcome non-adversarial competition growing active matter non-trivial, it depends on how like growth, proliferation degradation cellular are regulated confinement; regulation that happens even absence to achieve dynamic steady state known homeostasis. Here, we show passive by-products maintaining homeostasis can significantly alter fitness. Even purely pressure-regulated growth exclusively mechanical interactions, this enables with lower homeostatic pressure outcompete those higher pressure. We reveal interfaces play critical role specific kind competition: there, proportion cells better exploit local opportunities continuously arise keep system out equilibrium. elucidate effect theoretical toy model test an agent-based computational includes finite-time persistence dead thereby decouples density from Our results suggest self-organization aggregates into be decisive outcomes optimizing (active) important survival sensitivity cues.

Dead Code Elimination through Dependent Types

Pattern matching is an important feature in various functional programming languages such as SML, Caml, Haskell, etc. In these languages, unreachable or redundant matching clauses, which can be regarded as a special form of dead code, are a rich source for program errors. Therefore, eliminating unreachable matching clauses at compile-time can signiicantly enhance program error detection. Furthe...
