We show how to garble a large persistent database and then garble, one by one, a sequence of adaptively and adversarially chosen RAM programs that query and modify the database in arbitrary ways. Still, it is guaranteed that the garbled database and programs reveal only the outputs of the programs when run in sequence on the database. The runtime, space requirements and description size of the ...

We reinvestigate the oblivious RAM concept introduced by Goldreich and Ostrovsky, which enables a client, that can store locally only a constant amount of data, to store remotely n data items, and access them while hiding the identities of the items which are being accessed. Oblivious RAM is often cited as a powerful tool, which can be used, for example, for search on encrypted data or for prev...

Aims. We investigate the dependence of star formation and the distribution of the components of galaxies on the strength of ram pressure. Several mock observations in X-ray, Hα and HI wavelength for different ram-pressure scenarios are

High-end manycore microprocessors exhibit large-sized caches (32MB – 128MB) that consume a significant amount of total energy. These caches are typically composed of 6T-SRAM cells, which lack efficiency in terms of area and leakage power [1][2]. The emerging memory technologies, like Spin-Transfer Torque RAM (STT-RAM), not only incur reduced leakage power but also provide high integration densi...

Tensed clauses in Kashmiri are subject to the verb second constraint; the finite verbal element in these clauses always occurs in the second position, i.e. the position immediately following the first phrasal constituent. Like German however Kashmiri is argued to be underlyingly SOV. Evidence for underlying SOV word order comes primarily from environments where V2 does not apply such as non fin...

Storage deduplication has received recent interest in the research community. In scenarios where the backup process has to complete within short time windows, inline deduplication can help to achieve higher backup throughput. In such systems, the method of identifying duplicate data, using disk-based indexes on chunk hashes, can create throughput bottlenecks due to disk I/Os involved in index l...

We present the first 3D hydrodynamical simulations of ram pressure stripping of a disc galaxy orbiting in a galaxy cluster. Along the orbit, the ram pressure that this galaxy experiences varies with time. In this paper, we focus on the evolution of the radius and mass of the remaining gas disc and compare it with the classical analytical estimate proposed by Gunn & Gott (1972). We find that thi...
