This paper presents an architecture to evaluate the reliability of a systemon-chip (SoC) during its runtime that also accounts for the system’s redundancy. We propose to integrate an autonomic layer into the SoC to detect the chip’s current condition and instruct appropriate countermeasures. In the autonomic layer, error counters are used to count the number of errors within a fixed time interv...

The "middle-class neighborhood" is a breeding design intended to allow new mutations to accumulate by lessening the effects of purifying selection through the elimination of among-line fitness variation. We show that this design effectively applies soft selection to the experimental population, potentially causing biased estimates of mutational effects if social effects contribute to fitness.

ternative, however, requires a clear analysis of the origins of the crisis and a consistent set of principles for its resolution. Our aim here is to question two elements of traditional Marxist theory that we believe impede the development of such an analysis. One is the notion that the logic of accumulation is set by the character of capitalist social relations alone, the role of the state bei...

Learning a new language involves significant vocabulary acquisition. Learners can accelerate this process by relying on words with native-language overlap, such as cognates. For bilingual third language learners, it is necessary to determine how their two existing languages interact during novel language learning. A scaffolding account predicts transfer from either language for individual words...

Mortality and reproduction are intimately entwined in the study of aging and longevity. I apply the modern theory of complex adaptive systems (nonlinear, stochastic, dynamic methods) to questions of aging and longevity. I begin by highlighting major questions that must be answered in order to obtain a deeper understanding of aging. These are: (i) What should (in an evolutionary sense) mortality...

Glaciers are directly affected by the recent trends of global warming. Himalayan glaciers are located near Tropic of Cancer this belt receives more heat thus Himalayan glaciers are more sensitive to climate change. Major rivers of Asia originates from these glaciers and they are only source of fresh water for millions of people living in Indian sub-continent. Due to highly rugged terrain and in...

Collecting duct (CD) endothelin-1 (ET-1) is an important autocrine inhibitor of CD Na(+) reabsorption. Salt loading is thought to increase CD ET-1 production; however, definitive evidence of this, as well as understanding of the mechanisms transducing this effect, is lacking. Tubule fluid flow increases in response to Na(+) loading; hence, we studied flow modulation of CD ET-1 production. Three...
