We define the concept of and present provably secure constructions for Anonymous RAM (AnonRAM), a novel multi-user storage primitive that offers strong privacy and integrity guarantees. AnonRAM combines privacy features of anonymous communication and oblivious RAM (ORAM) schemes, allowing it to protect, simultaneously, the privacy of content, access patterns and user’s identity, from curious se...

background: the induction of cancer appears to be the most important effect of low-dose ionizing radiation to occur in an exposed population. in developing countries 94% of human radiation is from natural sources. in iran some high altitude regions such as, chaharmahal & bakhtiari has high levels of the natural background radiation (higher than the worldwide average). therefore, investigation o...

The Virgo cluster spiral galaxy NGC 4654 is supposed to be a good candidate for ongoing ram pressure stripping based on its very asymmetric Hi distribution. However, this galaxy also shows an asymmetric stellar distribution. Numerical simulations using ram pressure as the only perturbation can produce a tail structure of the gas content, but cannot account for its kinematical structure. It is s...

Similiar to a hard disk, NAND flash memory must be accessed in sector unit, and cannot be used for code storage without copying its contents to RAM. A virtual memory technique is promising as a RAM saving solution. However, it can not be easily used without the operating system supports, and it is not suitable for real time systems because it causes unpredicted execution delays. Virtual-ROM is ...

Recent research has proposed having a die-stacked last-level cache (LLC) to overcome the memory wall. Lately, spin-transfer-torque random access memory (STT-RAM) caches have received attention, since they provide improved energy efficiency compared with DRAM caches. However, recently proposed STT-RAM cache architectures unnecessarily dissipate energy by fetching unneeded cache lines (CLs) into ...

Oblivious RAM (O-RAM) is a useful primitive that allows a client to hide its data access patterns from an untrusted server in storage outsourcing applications. This paper proposes novel O-RAM constructions that achieves poly-logarithmic worst-case cost, while consuming constant client-side storage. Our techniques for constructing Oblivious RAM are fundamentally different from previous approache...

BACKGROUND Trauma center profiling is commonly performed with Standardized Mortality Ratios (SMRs). However, comparison of SMRs across trauma centers with different case mix can induce confounding leading to biased trauma center ranks. We hypothesized that Regression-Adjusted Mortality (RAM) estimates would provide a more valid measure of trauma center performance than SMRs. OBJECTIVE Compare...

introduction: cloning an individual by transferring somatic nuclei into enucleated recipient oocytes has already been well established. this technology also offers new opportunities to restore threatened species with interspecies somatic cell nuclear transfer (scnt). however, few mammalian species have been studied for their reproductive biology whereas huge differences have been observed betwe...

in-memory architecture that makes highly effective use of internal memory bandwidth by pitch-matching simple processing elements to memory columns. Computational RAM (also referred to as C•RAM) can function either as a conventional memory chip or as a SIMD (single-instruction stream, multiple-data stream) computer. When used as a memory, computational RAM is competitive with conventional DRAM i...

BACKGROUND  Improved thromboprophylaxis for acutely ill medical patients relies on valid predictions of thrombotic risks. Our aim was to compare the performance of the Improve and Geneva clinical risk assessment models (RAMs), and to simplify the current Geneva RAM. METHODS  Medical inpatients from eight Swiss hospitals were prospectively followed during 90 days, for symptomatic venous thromb...
