We propose a scheme for the observation of micro-macro entanglement in photon number based on amplifying and deamplifying a single-photon entangled state in combination with homodyne quantum state tomography. The created micro-macro entangled state, which exists between the amplification and deamplification steps, is a superposition of two components with mean photon numbers that differ by appr...

This paper is concerned with a numerical method for multiscale elliptic problems. Using the framework of the Heterogeneous Multiscale Methods (HMM), we propose a micro-macro approache which combines finite element method (FEM) for the macroscopic solver and the pseudospectral method for the micro solver. Unlike the micro-macro methods based on standard FEM proposed so far in HMM we obtain, for ...

An important issue regarding the deeper understanding of social and organisational phenomena is the interaction and the linkage between micro and macro layers. The micro-macro-link deals with the emergent aggregation of processes and actions on the micro-level and with structures, rules and roles on the macro-level. This paper presents recent results of the “socionics” project ASKO, which is a ...

In this address, I revisit the micro–macro problem in criminology, arguing for an “analytical criminology” that takes an integrated approach to the micro– macro problem. I begin by contrasting an integrated methodological-individualist approach with traditional holist and individualist approaches. An integrated approach considers the concept of emergence and tackles the difficult problem of spe...

We use agent-based modeling to investigate the effect of conservatism and partisanship on the efficiency with which large populations solve the density classification task - a paradigmatic problem for information aggregation and consensus building. We find that conservative agents enhance the populations' ability to efficiently solve the density classification task despite large levels of noise...

The multiple realizability of macro-level types does not, in my opinion, prove that “the explanations provided by the macro-theory [in which such types occur] will not, EVEN IN PRINCIPLE, be reducible to a micro-account” (Reconstructing Marxism, p. 120, my emphasis). For multiply-realizable macro-level types may be reducible to highly-complex disjunctions of micro-level types. (Indeed in such c...

A micro-level agent-based model of innovation diffusion was developed that explicitly combines (a) an individual's perception of the advantages or relative utility derived from adoption, and (b) social influence from members of the individual's social network. The micro-model was used to simulate macro-level diffusion patterns emerging from different configurations of micro-model parameters. Mi...

We study the implications of microeconomic heterogeneity for aggregate technology, showing that the aggregate elasticity of substitution between capital and labor can be expressed as a simple function of plant level structural parameters and sufficient statistics for plant heterogeneity. This allows for a new approach to estimating the aggregate elasticity using microeconomic data and allows us...

Viuhka is a compositional tool situated in PWGL. The system has been recently adapted in order to enhance our notation package. This paper contains a new notational short-hand, called macro-note, that can be used to realize short musical segments that have their lifespan within a macro-note. The system allows to generate various ornaments in the traditional sense, such as tremolos, trills, and ...

This thesis presents a new actuator system consisting of a micro-actuator and a macroactuator coupled in parallel via a compliant transmission. The system is called the Parallel Coupled Micro-Macro Actuator, or PaCMMA. In this system, the micro-actuator is capable of high bandwidth force control due to its low mass and direct-drive connection to the output shaft. The compliant transmission of t...
