Four states are enough!

چکیده
This paper presents a 1D intrinsically universal cellular automaton with four states for a first neighbors neighborhood, improving on the previous lower bound and getting nearer to the Turing universality bound. Intrinsic universality is discussed. Construction and proof rely on a combination of bulking techniques with programming using particles and collisions.

Dynamics Analysis of the Steady and Transient States of a Nonlinear Piezoelectric Beam by a Finite Element Method
This paper presents a finite element formulation for the dynamics analysis of the steady and transient states of a nonlinear piezoelectric beam. A piezoelectric beam with damping is studied under harmonic excitation. A numerical method is used for this analysis. In the paper, the central difference formula of four order is used and compared with the central difference formula of two order in th...
متن کاملThe Global Health Policies of the EU and its Member States: A Common Vision?
Background This article assesses the global health policies of the European Union (EU) and those of its individual member states. So far EU and public health scholars have paid little heed to this, despite the large budgets involved in this area. While the European Commission has attempted to define the ‘EU role in Global Health’ in 2010, member states are active in the domain of global health ...
متن کاملIterated GSM Mappings: A Collapsing Hierarchy
With motivations from various areas (Lindenmayer systems, iterated reading of literary works, self-generated in nite sequences, \computing by carving" as suggested in the DNA computing area), in several places mechanisms based on iterated (non-deterministic) nite state sequential transducers were considered. It is known that such mechanisms can characterize the family of recursively enumerable ...
متن کاملState Support: A Prerequisite for Global Health Network Effectiveness; Comment on “Four Challenges that Global Health Networks Face”
Shiffman recently summarized lessons for network effectiveness from an impressive collection of case-studies. However, in common with most global health governance analysis in recent years, Shiffman underplays the important role of states in these global networks. As the body which decides and signs international agreements, often provides the resourcing, and is responsible for implementing ini...
متن کاملDecoherence effects on quantum Fisher information of multi-qubit W states
Quantum fisher information of a parameter characterizing the sensitivity of a state with respect to parameter changes. In this paper, we study the quantum fisher information of the W state for four, five, six and seven particles in decoherence channels, such as amplitude damping, phase damping and depolarizing channel. Using Krauss operators for decoherence channels components, we investigate t...
