of [Nemo97]: Single-event upset (SEU) tolerance for commercial 1Mbit SRAMs, 4Mbit SRAMs, 16Mbit DRAMs and 64Mbit DRAMs was evaluated by irradiation tests using high-energy heavy ions with an LET range between 4.0 and 60.6 MeV/(mg/cm2). The threshold LET and the saturated cross-section were determined for each device from the LET dependence of the SEU cross-section. We show these test results an...

Non-melanoma skin cancers are the most commonly diagnosed forms of cancer in Canada (approximately 72,000 cases across the country in 2002). After this type of skin cancer, prostate, breast, colorectal, and lung cancers are the most frequently diagnosed and account for 56% (57% provincially) of total reported cancer cases in Waterloo Region within the past five years. They are also the leading ...

This article presents a systematic review of outcomes associated with the use of microprocessorcontrolled prosthetic knees (MPKs) compared with non–microprocessor-controlled prosthetic knees (NMPKs) among individuals with unilateral transfemoral limb loss (TFLL). A comprehensive review of 27 publications revealed that MPKs may be indicated in cases where improved ambulatory safety and the abili...

Frequent exploratory eye-movements called saccades pose for the visual system the problem of combining information from successive fixations into an apparently seam less conscious experience. A new study shows that information from successive fixations is combined, not by fusing fixation 'snapshots', but by integrating more complex visual attributes at a mid-high level of analysis.
