The spatial distribution of single Au atoms on a thin FeO film has been investigated by low-temperature scanning tunneling microscopy and spectroscopy. The adatoms preferentially adsorb on distinct sites of the Moiré cell formed by the oxide layer and the Pt(111) support and arrange into a well-ordered hexagonal superlattice with 25 angstroms lattice constant. The self-organization is the conse...

While Korea does not have any legal statement on surrogacy, treatments are carried out in practice. As a result, every Institutional Review Board (IRB) of each fertility clinic faces an ethical predicament in reviewing each case. There is a need to arrange the institutions' own standards of surrogate pregnancy procedures before the establishment of national or professional regulation. This arti...

Medical classifications define and describe specific and characteristic features of disease entities and arrange them in an order [10]. The classifications thus represent a central component of medical pathology and are the conceptual and clinical basis for the 1. diagnosis, 2. therapy and 3. prognosis of diseases [10]. Particularly for diseases with low case numbers, a common classification is...

The paper is devoted to the problem of mapping affine loop nests onto distributed memory parallel computers. A method to find affine transformations of loop nests for parallel execution and distribution of data over processors is presented. The method tends to minimize the number of communications between processors and to improve locality of data within one processor. A problem of determinatio...

XQuery is a query language for data stored in xml form. It can be used to search such documents and arrange the result, as an xml structure or a simple text (possibly suitable for a TEX engine). Like xslt 2.0, it is based on XPath 2.0. We propose an introduction to XQuery, and some comparisons with xslt allow readers to discern the applications XQuery is suitable for.

This paper is concerned with a case study in content-based classification of textual documents. In particular we compare the application of two prominent self-organizing neural networks to the same problem domain, namely the organization of software libraries. The two models are Adaptive Resonance Theory and Self-Organizing Maps. As a result we are able to show that both models successfully arr...

This paper discusses current conceptions of ontology in computer science focussing on cultural specification and temporalization. It is pointed out, first, that ontologies arrange the world, they do not represent it; second, that ontologies, except logical Formal Ontologies, can be developed within a cultural framework; third, Top Level and Domain Ontologies have to be complemented by Pragmatic...

We study the relation between α-helix formation and folding for a simple artificial peptide, Ala10Gly5-Ala10. Our data rely on multicanonical Monte Carlo simulations where the interactions among all atoms are taken into account. The free-energy landscape of the peptide is evaluated for various temperatures. Our data indicate that folding of this peptide is a two-step process: in a first step tw...

Many association rule algorithms operate in a parallel environment where the database is divided up among a number of processors, a procedure which is usually carried out indiscriminately. The nature of the database partitioning can affect both the number of candidate sets produced and the workload at each processor. This paper demonstrates that Principal Component Analysis can be used successf...

One of the biggest challenges in crowdsourcing is quality control which is to expect high quality results from crowd workers who are not necessarily very capable nor motivated. In this paper, we consider item ordering questions, where workers are asked to arrange multiple items in the correct order. We propose a probabilistic generative model of crowd answers by extending a distance-based order...
