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...

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...

Garbled RAM, introduced by Lu and Ostrovsky (Eurocrypt 2013), provides a novel method to garble RAM (Random Access Machine) programs directly. It can be seen as a RAM analogue of Yao’s garbled circuits such that, the size of the garbled program and the time it takes to create and evaluate it, is proportional only to the running time of the RAM program, avoiding the inefficient process of first ...

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...

Ram seminal plasma increases the fertility of frozen-thawed ram spermatozoa deposited into the cervix. The aim of the current study was to compare the effect of ram seminal plasma to that of bull seminal plasma, dog prostatic fluid, protein-free TALP TrilEq (Triladyl with 0.5 mt of Equex STM paste added to each 100 mt) and heat-treated skim milk on longevity and percentages of progressively mot...

In recent years, a rapidly growing number of small embedded systems have been used in very high volumes. One example is the automotive industry, where the number of Electronic Control Units (ECU) in a single car is approaching 100 for high end automobiles and several dozens are used in mid-range cars. Small system-on-chip microcontrollers are often used with static operating systems. As on-chip...

Maturation and translation of mRNA in eukaryotes requires the addition of the 7-methylguanosine cap. In vertebrates, the cap methyltransferase, RNA guanine-7 methyltransferase (RNMT), has an activating subunit, RNMT-Activating Miniprotein (RAM). Here we report the first crystal structure of the human RNMT in complex with the activation domain of RAM. A relatively unstructured and negatively cha...

When a sufficient current density passes through the MTJ, the spin-polarized current will exert a spin transfer torque to switch the magnetization of the free layer. This is the fundamental of the novel write mechanism in STT-RAM, current-induced magnetization switching. It allows STT-RAM to have a smaller cell size and write current than MRAM, and also capable of what MRAM promises: fast, dens...
