How fast does Langton’s ant move?
The automaton known as ‘Langton’s ant’ exhibits a dynamical transition from a disordered phase to an ordered phase where the particle dynamics (the ant) produces a regular periodic pattern (called ‘highway’). Despite the simplicity of its basic algorithm, Langton’s ant has remained a puzzle in terms of analytical description. Here I show that the highway dynamics obeys a discrete equation where...
متن کاملHow and why does the endoplasmic reticulum move?
The ER (endoplasmic reticulum) is a fascinating organelle that is highly dynamic, undergoing constant movement and reorganization. It has many key roles, including protein synthesis, folding and trafficking, calcium homoeostasis and lipid synthesis. It can expand in size when needed, and the balance between tubular and lamellar regions can be altered. The distribution and organization of the ER...
متن کاملHow Mesp1 makes a move
The transcription factors Mesp1 and Mesp2 have essential roles in the migration and specification of multipotent progenitor cells at the onset of cardiogenesis. Chiapparo et al. (2016. J. Cell Biol http://dx.doi.org/10.1083/jcb.201505082) identify common Mesp functions in fate specification and Mesp1-specific targets controlling the speed and direction of progenitor cell migration.
متن کامل1 Does the Verb Move in Russian ?
It has generally been agreed that a verb feature on v necessitates overt short movement of the verb to the head of vP (see Bailyn 1995 for arguments). However, the verb feature on T has been an issue of longstanding debate in Russian linguistics. In order to derive various temporal references, the verb feature on T must be checked by the verb (Chomsky 2001). So the question arises whether this ...
متن کاملDoes the Beige Book Move Financial Markets?
About two weeks prior to each Federal Open Market Committee (FOMC) meeting, the Federal Reserve releases a description of economic activity in a document called the Beige Book. By creating a quantitative index of these qualitative reports, we examine whether the content of the Beige Book affects asset prices. The results indicate that more positive Beige Book reports on economic growth are asso...
