This paper describes the design and fabrication of a "pop-up" electrochemical paper-based analytical device (pop-up-EPAD) to measure beta-hydroxybutyrate (BHB)-a biomarker for diabetic ketoacidosis-using a commercial combination BHB/glucometer. Pop-up-EPADs are inspired by pop-up greeting cards and children's books. They are made from a single sheet of paper folded into a three-dimensional (3D)...

Rapid Single Flux Quantum (RSFQ) logic is a superconducting digital circuit technology that has emerged as a possible alternative to advanced semiconductor technologies for large scale ultra-high speed, very low power digital applications. Timing of RSFQ circuits at frequencies of tens to hundreds of gigahertz is a challenging and still unresolved problem. In many circuit topologies of current ...

There are two varieties of timing games in economics: Having more predecessors helps in a war of attrition and hurts in a pre-emption game. This paper introduces and explores a spanning class with rank-order payoffs that subsumes both as special cases. Given unobserved actions and complete information, we identify equilibria with a rich enough structure to capture a wide array of economic and s...

This research adopted a model of goal activation to study the mechanisms underlying interrupted task performance. The effects of interruption timing, type of interruption, and age on task time and primary task resumption time were explored under conditions in which attention was switched back and forth between two tasks, much as when drivers shift attention between attending to the road and to ...

the purpose of the present study was to examine the effects of self – control modeling , that is presenting moded to learner whenever they asked for it, on learning a timing task.twenty four right handed subjects (12 males, 12 females, aged 19-20) voluntarily participated in the study and were assigned randomly to two groups of self – control and yoked.the task was pressing the keys number 1, 4...

The push for higher recording densities has motivated the development of iterative errorcontrol codes of unprecedented power, whose large coding gains enable low error rates at very low SNR [1] [2]. In addition, the iterative decoding technique has been extended to turbo equalization, where the equalizer and the decoder iterate [3]. Consequently, timing recovery, which typically derives no bene...

one pollutant which seriously threatens water resources is dye. therefore, finding a suitable method to separate the dye in water resources is very important. an adsorption process that uses low cost adsorbents is considered as an efficient strategy for this purpose. in this study, erythrosine dye removal from an aquatic environment using natural absorbents, namely sorghum and ziziphus nummular...
