Concurrency of partnerships, consistency with data, and control of sexually transmitted infections
Epidemics, 2018 Sexually transmitted infections (STIs) are a globally increasing public health problem. Mathematical models, carefully matched to available epidemiological and behavioural data, have an important role to play in predicting the action of control measures.

Visualizing Concurrency Control Algorithms for Real-Time Database Systems
Data Science Journal, 2008 This paper describes an approach to visualizing concurrency control (CC) algorithms for real-time database systems (RTDBs). This approach is based on the principle of software visualization, which has been applied in related fields.

An efficient locking model for concurrency control in OODBS
Data Science Journal, 2006 When several transactions execute concurrently in a database, the isolation property may no longer be preserved. It is necessary for the system to control the interaction among the concurrent transactions.

On Optimistic Methods For Concurrency Control [PDF]
Fifth International Conference on Very Large Data Bases, 1979., 1979 Most current approaches to concurrency control in database systems rely on locking of data objects as a control mechanism. In this paper, two families of nonlocking concurrency controls are presented. The methods used are “optimistic” in the sense that they rely mainly on transaction backup as a control mechanism, “hoping” that conflicts between ...

Critical Care, 2020 Background Conceptually, the “control of gut overgrowth” (COGO) is key in mediating prevention against infection with Gram-negative bacilli by topical antibiotic prophylaxis, a common constituent of selective digestive decontamination (SDD) regimens ...

The Logical Timestamp Skew Anomaly in Event-Replicated Transaction Schedulers
IEEE Access, 2021 To sidestep reasoning about the complex effects of concurrent execution, many system designers have conveniently embraced strict serializability on the strength of its claims, support from commercial and open-source database communities and ubiquitous ...

Intelligent Transaction Scheduling to Enhance Concurrency in High-Contention Workloads
Applied SciencesConcurrency control (CC) scheme based on transaction decomposition has significantly enhanced the concurrency performance of multicore in-memory databases, surpassing traditional CC schemes such as two-phase locking (2PL) or optimistic concurrency ...
