The group abstraction is a crucial element in the support provided by middleware platforms. Application areas such as CSCW, dependable systems or media dissemination can take advantage of groups to facilitate the communication and management of the several end-points participating in the application. Although there have been proposals for the provision of groups in CORBA and other middleware pl...

The sequential use of chemotherapy and surgery in the treatment of osteosarcoma developed in an empirical fashion without the benefit of investigations in animal models. The MGH-OGS murine osteosarcoma is a transplantable tumor that resembles the human disease with respect to histology, local invasiveness, metastatic characteristics, tumor ploidy, and its response to chemotherapy. We have used ...

The GARF, Bast, and OGS systems represent the resulting efforts of a multi-year ‘object group’ program at the Swiss Federal Institute of Technology in Lausanne. The intent of the program was to understand the extent to which one could build flexible and performance system supports to encapsulate object plurality. That is, we experimented with various ways to build libraries and services to supp...

Abstract The COVID-19 pandemic is changing future trends in retailing and e-commerce immensely. Recent research revealed a considerable increase online grocery shopping (OGS) since the started. In addition, current statistics indicate steady OGS over coming years. Despite this, less known about whether consumers’ behavior evolving to ‘new normal’ or returning ‘old habits’ after restrictions are...

Oxidized graphene sheets (OGS) were treated with a hyperbranched polyethylenimine (PEI) under hydrothermal conditions to generate nanocomposites of graphene quantum dots (GQDs) functionalized with PEI (GQD-PEIs). The influence of the reaction temperature and the PEI/OGS feed ratio on the photoluminescence properties of the GQD-PEIs was studied. The obtained GQD-PEIs were characterized by TEM, d...

Traditional hierarchical modelling methods tend to have layers of abstraction corresponding to naturally existing layers of concern in multilevel systems. Although convenient, this is not always optimal for analysis and design. For instance, parts of a system which are in the same layer may not contribute to the same degree on some metric, e.g. system power consumption. To moderate the modellin...

OBJECTIVES The esthetic and functional results of orthognathic surgery of severe dentofacial deformities are predictable, however there are differences regarding the effects on stomatognathic system. The aim was to investigate the effects of orofacial myofunctional therapy (OMT) on the masticatory function in individuals with dentofacial deformity submitted to orthognathic surgery (OGS). MATE...

This investigation compares the treatment outcome of early treatment (in the mixed dentition) with that of late treatment (early permanent dentition) using objective evaluation criteria. Pretreatment and post-treatment records of all patients (n = 512) completed from 1998 to 2000 in the graduate orthodontics clinic at the Indiana University School of Dentistry (IUSD) were evaluated by the Ameri...

Over the past decade, market for off-grid solar (OGS) systems providing affordable sources of energy has seen a remarkable expansion in many developing countries where coverage by electricity grid is limited. The observed growth been fuelled provision finance variety foreign investors to private suppliers such systems. development OGS plays an important part meeting imperative ensuring access s...
