The Hydraulic Ram

RV form and function: a piston pump, vortex impeller, or hydraulic ram?

d n d T he iPIX by Saremi et al. (1) in this issue of iJACC highlights the precision of current imaging techniques in displaying the complex 3-dimensional structure of the right entricle (RV). The investigators illustrate the inricacy of normal RV geometry, highlighting the istributions of anatomical folds, irregular trabeulations and, more importantly, the RV inundibulum. These remarkable pict...

The Adaptive Weight Using RAM

This article analyses the saturation problem of a RAM neural network, a n-tuple classifier [1] containing 340 12-input neurons applied to the character recognition task, using the British mail data bank [2]. It presents data to evaluate this problem and correlates it to other characteristics of the RAM nets [3] [4]. Therefore, two novel approaches were suggested to reduce the network saturation...

The aetiology of ram epididymitis.

A wide variety of organisms from the environment invade the preputial cavity of rams. Various of these organisms can be isolated from the deeper parts of the male genital tract, and especially from the accessory glands. Some of the bacteria present in the sheath can be stimulated to migrate to the deeper parts of the genital tract by injections into the host animal of luteinizing-hormone-releas...

Anonymous RAM

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...
