Cloud computing markets face challenges, such as a large variety of different resource types in the market. A large variety of resource types results in a low number of matches of ask and bids. Consequently, the market has a low liquidity, which is economically inefficient and can lead to market failure. To counteract this problem, SLA templates (i.e., templates for electronic contracts) have b...

In the history of SLA research, the relationship between explicit and implicit knowledge has incited heated debate, culminating in, broadly, three disparate positions: (a) the non-interface; (b) the weak-interface; and (c) the stronginterface. In this paper, we re-engage the theoretical debate. Unlike the previous discussions, however, which typically find researchers espousing one position aga...

This case study reports a rare variation of the superior laryngeal artery (SLA), which is the principal arterial supply of the larynx. The knowledge of the arterial variations is essential for the surgeons to prevent blood loss and postoperative complications. During routine dissection of an adult male cadaver, a rare arterial variation in the SLA was seen. In this case, the SLA passed through ...

SLA monitoring is difficult to automate as it would need precise and unambiguous specification and a customizable engine that collects the right measurement, models the data and evaluates the SLA at certain times or when certain events happen. Also most of the SLA neglect client side measurement or restrict SLAs to measurements based only on server side. In a cross-enterprise scenario like web ...

Service-level agreements (SLA) definition and monitoring are open issues within the IT Service Management (ITSM) domain. Our main goals are to propose a model-based approach to IT services SLA specification and compliance verification. The specification will be accomplished by proposing a SLA language a domain specific language for defining quality attributes as non functional requirements (NFR...

The mechanisms by which CTLA4Ig exerts its powerful immunomodulatory effects are not clear. We show here that CTLA4Ig can induce linked regulation of allogeneic porcine T cell responses in vitro. Naive miniature swine SLA(dd) T cells were rendered hyporesponsive to specific allogeneic Ag after coculturing with MHC-mismatched SLA(cc) stimulators in the presence of CTLA4Ig. These Ag-specific hypo...

To the Editor: Antibodies to a cytosolic soluble liver antigen (SLA), originally detected by an inhibition ELISA using cytosolic liver fractions and proposed as marker of a third type of autoimmune hepatitis (AIH) negative for other autoantibodies, have been also reported in anti-nuclear and/or -smooth muscle antibody type 1 AIH, liver kidney microsomaltype 2 AIH, and autoimmune sclerosing chol...

Due to the large variety in computing resources, Cloud markets often suffer from a low probability of finding matches between consumers’ bids and providers’ asks, resulting in low market liquidity. The approach of service level agreement (SLA) templates (i.e., templates for electronic contracts) is a mean to reduce this variety as it channels the demand and supply. However, until now, the SLA t...

The increased reliance of companies on IT outsourcing has turned management attention to a set of skills of managing relationships with service providers. While practitioners proclaimed that a key to managing outsourcing relationships was with SLA, there existed very little understanding of how effectiveness and impact of SLA on IT outsourcing arrangements was measured. Using a conceptual frame...
