Journaling has been a popular reliability tool for file systems. However, journaling may involve writing updates twice, once to the journal, and once to potentially random update locations. The journal granularity tends to be coarse, leading to more bytes written than necessary. We introduce Fine-grained Journal Store (FJS). Finegrained Journal Store uses the journal as the final storage locati...

Traditionally, concurrent data structures are protected by a single mutual exclusion lock so that only one thread may access the data structure at any time. This coarse-grained approach makes it relatively easy to reason about correctness, but it severely limits parallelism. More advanced algorithms instead perform synchronisation at a finer grain. They employ sophisticated synchronisation sche...

This paper presents experiments extending the work of Ba et al. (2014) on recurrent neural models for attention into less constrained visual environments, beginning with fine-grained categorization on the Stanford Dogs data set. In this work we use an RNN of the same structure but substitute a more powerful visual network and perform large-scale pre-training of the visual network outside of the...

A bstract We analyze gravitational particle production assisted by chemical potential. By utilizing the uniformly smoothed Stokes-line method and Borel summation, we gain insight into fine-grained history of enhanced production. Analytic/semi-analytic formulae describing amount, time width are obtained for both spin-1 spin-1/2 particles in various FRW spacetimes. Our work also serves as a concr...

Authigenic seafl oor carbonate crusts include fenestrate microbialite, thrombolite, and four types here designated: Fine-grained Crust, Sparry Crust, Hybrid Sparry Fine-grained Crust, and Sparry Crust plus Coarse Grains. Each of the latter four types includes at least some layered examples that have generally been regarded as stromatolites. Recognition and interpretation of these various deposi...

ABSTRACT  Introduction: Recently uses of medium and high energy x-rays has been increased in Iran and radiotherapy centers along with a variety of accelerators have been installed in some provinces. In the other hand there is no sufficient skill in designing and making radiotherapy treatment rooms. This study was conducted to evaluate the efficacy of different m...
