When a node in a distributed storage system fails, it needs to be promptly repaired to maintain system integrity. While typical erasure codes can provide a significant storage advantage over replication, they suffer from poor repair efficiency. Locally repairable codes (LRCs) tackle this issue by reducing the number of nodes participating in the repair process (locality), with the cost of reduc...

Probabilistic expectations and memory limitations are central factors governing the real-time comprehension of natural language, but how the two factors interact remains poorly understood. One respect in which the two factors have come into theoretical conflict is the documentation of both locality effects, in which more dependents preceding a governing verb increase processing difficulty at th...

We study refinement in the setting of local reasoning. In particular, we explore general translations that preserve and that break locality.

Introduction Mermin non-locality generalised to abstract process theories Introduction Mermin non-locality generalised to abstract process theories Here we give the full necessary and sufficient conditions for Mermin non-locality of an abstract process theory: Mermin non-locality ⇐⇒ algebraically non-trivial phases

Locality has long been seen as a crucial property for the efficiency of Evolutionary Algorithms in general, and Genetic Programming (GP) in particular. A number of studies investigating the effects of locality in GP can be found in the literature. The majority of the previous research on locality focuses on syntactic aspects, and operator semantic locality has not been thoroughly tested. In thi...

As the disparity between processor and main memory performance grows, the number of execution cycles spent waiting for memory accesses to complete also increases. As a result, latency hiding techniques are critical for improved application performance on future processors. In this paper we examine the spatial locality characteristics of several applications, and show that spatial locality varie...

Hardware and software cache optimizations are active elds of research, that have yielded powerful but occasionally complex designs and algorithms. The purpose of this paper is to investigate the performance of combined though simple software and hardware optimizations. Because current caches provide little exibility for exploiting temporal and spatial locality, two hardware modiications are pro...

Robert Griffiths has recently addressed, within the framework of a ‘consistent quantum theory’ that he has developed, the issue of whether, as is often claimed, quantum mechanics entails a need for faster-than-light transfers of information over long distances. He argues that the putative proofs of this property that involve hidden variables include in their premises some essentially classical-...

this study was performed in year 2010 to evaluate the effect of locality and date of collection on germination and growth of pimpinella aurea dc. seed. the experiment was a factorial one, based upon a completely randomized design of four replications. seeds were collected from three localities in tehran province (tochal, vardavard and lavasanat), at their initial developmental and fully develop...

In multithreaded object-oriented programs, locality refers to the dynamic scoping relation among threads and objects in a potentially shared-memory context. This paper calls for type-theoretic investigations into two forms of locality – thread locality and aggregate locality – and proposes a unified type inference algorithm to reason about them over unannotated real-world Java programs.
