Researchers in spatial cognition have debated for decades the specificity of the mechanisms through which spatial information is processed and stored. Interestingly, although rodents are the preferred animal model for studying spatial navigation, the behavioral methods traditionally used to assess spatial memory do not effectively test the predictions of specificity in their representation. To ...

We present Lilac-TM, the first locality-aware Distributed Software Transactional Memory (DSTM) implementation. Lilac-TM is a fully decentralized lease-based replicated DSTM. It employs a novel self-optimizing lease circulation scheme based on the idea of dynamically determining whether to migrate transactions to the nodes that own the leases required for their validation, or to demand the acqui...

Data locality is a key factor for the performance of parallel systems. In a Distributed Shared Memory (DSM) system, however, it is difficult for the users to maintain a high data locality as it is usually a priori unknown how the data is distributed among the nodes. In this article we introduce a monitoring framework that allows users to understand the memory behavior of parallel applications. ...

Dynamic loop scheduling algorithms can suuer from overheads due to synchronisation, loss of locality and small iteration counts. We observe that timing information from previous executions of the loop can be utilised to reduce these overheads. We introduce two new algorithms for dynamic loop scheduling which implement this type of feedback guidance, and report experimental results on a distribu...

There are many different notions of optimality even in testing a single hypothesis. In the multiple testing area, the number of possibilities is very much greater. The paper first will describe multiplicity issues that arise in tests involving a single parameter, and will describe a new optimality result in that context. Although the example given is of minimal practical importance, it illustra...

HIGHLIGHTS This study tested the effects of adolescent-stress on adult learning and memory.Adolescent-stressed rats had enhanced reversal learning compared to unstressed rats.Adolescent-stress exposure made working memory more vulnerable to disturbance.Adolescent-stress did not affect adult associative learning or reference memory. Exposure to acute stress can cause a myriad of cognitive impair...

This paper describes equals, a fast parallel implementation of a lazy functional language on a commercially available shared-memory parallel machine, the Sequent Symmetry. In contrast to previous implementations, we detect parallelism automatically using strictness analysis. Another important diierence between equals and previous implementations is the use of reference counting for memory manag...

The prior literature reports that the activation of conceptual processing is necessary, albeit insufficient, for the detection of implicit mood-congruent memory bias. The purpose of this research was to investigate the effects of self-referential processing on this bias in individuals with subclinical depression. Two groups of participants (subclinical depressed vs. non-depressed) were set a pe...

For intelligent agents modeled to emulate people, reference resolution is memory management: when processing an object or event – whether it appears in language or in the simulated physical or cognitive experience of the agent – the agent must determine how that object or event correlates with known objects and events, and must store the new memory with semantically explicit links to related pr...
