Thermal considerations play an increasingly important role in the design of new processors. Thermal concerns impact how chips are laid out, how quickly processors can be clocked, processor reliability, and how expensive the packaging is. Current production chips are often packaged to dissipate maximum typical power, rather than maximum absolute power. We investigate techniques which would allow...

We describe here the construction and testing of an IRA with dual polarity. Four feed arms are evenly spaced around the reflector, and each channel consists of a pair of arms on opposite sides of the reflector. Each channel uses a standard balun to convert the 50-ohm input impedance to 200 ohms. Since the characteristic impedance of each channel is 400 ohms, there is a 2:1 impedance mismatch at...

Our goal is to investigate the definition and application of strong consistency properties on the dual graphs of binary Constraint Satisfaction Problems (CSPs). As a first step in that direction, we study the structure of the dual graph of binary CSPs, and show how it can be arranged in a triangle-shaped grid. We then study, in this context, Relational Neighborhood Inverse Consistency (RNIC), w...

Recent years have seen an increasing interest in developing standards for linguistic annotation, with a focus on the interoperability of the resources. This effort, however, requires a profound knowledge of the advantages and disadvantages of linguistic annotation schemes in order to avoid importing the flaws and weaknesses of existing encoding schemes into the new standards. This paper address...

We consider the problem of model selection and estimation in sparse high dimensional linear regression models with strongly correlated variables. First, we study the theoretical properties of the dual Lasso solution, and we show that joint consideration of the Lasso primal and its dual solutions are useful for selecting correlated active variables. Second, we argue that correlation among active...

Previously, we determined the incidence of dual infections in a South African cohort and its association with higher viral setpoint. Ten years later, we compare the incidence and impact of dual infections at transmission on viral setpoint in a geographically similar cohort (n = 46) making use of both the heteroduplex mobility assay (HMA) and the more recent single genome amplification (SGA) app...
