چکیده

The atomic surface structure of compound semiconductors plays a large role in the growth of semiconductor films and the final microstructure of the film. During growth of InxGa1−xAs films, a mixed-termination surface consisting of a (4x3) reconstruction with common binary InAs or GaAs reconstructions, such as the α2(2x4), has been observed. We have used Density Functional Theory (DFT) to determine the effects of strain and alloying on the α2(2x4) reconstruction and combined DFT calculations and simulated Scanning Tunneling Microscopy (STM) images to determine the structure of the (4x3) reconstruction.

A Hierarchical LSP Management Architecture for MPLS Traffic Engineering

In this paper, we propose a scalable Label Switched Path (LSP) management architecture for Multiprotocol Label Switching (MPLS) traffic engineering using a hierarchical network model. MPLS introduces the concept of a label hierarchy to support scalability by lessening the complexity of transit routers for the computation of complete routing tables. However, this hierarchical network model creat...

Content-Structural Relation Inference in Knowledge Base

Relation inference between concepts in knowledge base has been extensively studied in recent years. Previous methods mostly apply the relations in the knowledge base, without fully utilizing the contents, i.e., the attributes of concepts in knowledge base. In this paper, we propose a contentstructural relation inference method (CSRI) which integrates the content and structural information betwe...

Apparent seasonality of parasite dynamics: analysis of cyclic prevalence patterns.

Seasonal disease dynamics are common in nature, but their causes are often unknown. Our case study provides insight into the cyclic prevalence pattern of the horizontally and vertically transmitted microsporidium Octosporea bayeri in its Daphnia magna host. Data from several populations over a four year period revealed a regular prevalence increase during summer and a decrease over winter when ...

Costing Psychiatric Interventions

The demands and needs for cost information in psychiatric contexts have multiplied considerably in recent years, but have often been frustrated by inadequate data. The typical costs data available to the policy maker, manager, clinical professional or researcher have been dominated until recently by age-old accounting practices and line management arrangements, and constrained by fragmentation ...

Periodical cicadas use light for oviposition site selection.

Organisms use incomplete information from local experience to assess the suitability of potential habitat sites over a wide range of spatial and temporal scales. Although ecologists have long recognized the importance of spatial scales in habitat selection, few studies have investigated the temporal scales of habitat selection. In particular, cues in the immediate environment may commonly provi...
