Product assembly design is a complex activity possible involving collaboration between different designers geographically dispersed. This paper puts forward some significant methodologies and technologies for distributed assembly and presents a collaboration architecture that manages to support working in both synchronous and asynchronous ways. Meanwhile, we adopt a three-level conflicts detect...

The use of modern technology in the construction of accurate solid macromolecular models based on atomic coordinates and electron density functions has led us to re-examine the usefulness of physical models as tools for understanding molecular assembly and for designing detailed experimental and computational studies of the assembly process. Recent developments include the construction of new m...

Self-similar groups are a fascinating area of current research. Here we give a short, and hopefully accessible, introduction to them.

Background: Differing perspectives of self-harm may result in a struggle between

The structure of a self-similar group G naturally gives rise to a transformation which assigns to any probability measure μ on G and any word w in the alphabet of the group a new probability measure μ. If μ is a convex combination of μ and the δ-measure at the group identity, then the asymptotic entropy of the random walk (G,μ) vanishes; therefore, the random walk is Liouville and the group G i...

A survey was conducted to investigate how self-perception of text-message dependency leads to psychological/behavioral symptoms in relation to personality factors. Japanese high school students completed a self-report questionnaire measuring frequency of text-messages, self-perception of textmessage dependency, psychological/behavioral symptoms, extroversion and neuroticism. Self-perception of ...

The fabrication methods of the microelectronics industry have been refined to produce ever smaller devices, but will soon reach their fundamental limits. A promising alternative route to even smaller functional systems with nanometre dimensions is the autonomous ordering and assembly of atoms and molecules on atomically well-defined surfaces. This approach combines ease of fabrication with exqu...
