Rethinking serializable multiversion concurrency control [PDF]
Proceedings of the VLDB Endowment, 2015 Multi-versioned database systems have the potential to significantly increase the amount of concurrency in transaction processing because they can avoid read-write conflicts. Unfortunately, the increase in concurrency usually comes at the cost of transaction serializability.

Cache Serializability: Reducing Inconsistency in Edge Transactions
, 2015 Read-only caches are widely used in cloud infrastructures to reduce access latency and load on backend databases. Operators view coherent caches as impractical at genuinely large scale and many client-facing caches are updated in an asynchronous manner ...

Serializability theory for replicated databases
Journal of Computer and System Sciences, 1985 In a one-copy distributed database, each data item is stored at exactly one site of a distributed system. In a replicated database, some data items are stored at multiple sites. The main motivation for replicated data is improved reliability: by storing important data at multiple sites, the system can tolerate failures more gracefully.

Concurrence control for transactions with priorities [PDF]
, 1989 Priority inversion occurs when a process is delayed by the actions of another process with less priority. With atomic transactions, the concurrency control mechanism can cause delays, and without taking priorities into account can be a source of priority

An Assertional Characterization of Serializability [PDF]
, 1989 Serializability is usually defined operationally in terms of sequences of operations. This paper gives another definition of serializability-in terms of sequences of states. It also shows how this definition can be used to prove correctness of solutions to the concurrency control problem.

A Task and Motion Planning Framework for Partially Observable Household Manipulation Scenes
Advanced Intelligent Systems, EarlyView.This paper presents a novel TAMP framework tackling partial observability, cluttered scenes, and vague goals via symbolic reasoning and occlusion‐aware planning. It outperforms prior learning, policy, and LLM‐based methods in six real and simulated household tasks.

Nanomechanical Systems for Reservoir Computing Applications
Advanced Intelligent Systems, EarlyView.Nanoelectromechanical systems (NEMS) are known for their strong nonlinear response, which can be conducive for reservoir computing. In this work, the authors build an NEMS‐based reservoir and investigate the classification accuracy as a function of drive levels and operation points.

Serializable isolation for snapshot databases [PDF]
Proceedings of the 2008 ACM SIGMOD international conference on Management of data, 2008 Many popular database management systems implement a multiversion concurrency control algorithm called snapshot isolation rather than providing full serializability based on locking. There are well-known anomalies permitted by snapshot isolation that can lead to violations of data consistency by interleaving transactions that would maintain consistency

The importance of science communication and public engagement to professional associations
Anatomical Sciences Education, EarlyView.Scientists have gathered in professional associations to promote science to the public. The American Association for Anatomy (AAA) has invested resources in programs to promote anatomical sciences to the public (high school level via the Anato‐Bee; all levels via Anatomy nights) and train scientists how to talk to the public (SciComm Bootcamp ...
