This paper presents a 10-bit high-speed two-stage SAR ADC. Each bit uses a dedicated comparator to store its output and generate an asynchronous clock for the next comparison. By doing this, the SAR logic delay and power are significantly reduced. A modified bidirectional single-side switching technique is used to optimize the comparator speed and offset by controlling the input common mode vol...

This paper presents a high dynamic range (DR), power efficient VCO-based continuous time ΔΣ modulator (CTDSM). It introduces a simple, robust and low power fully digital phase extended quantizer (PEQ) that doubles the VCO quantizer resolution compared to conventional XOR-based phase detector with minimum overhead. A tri-level resistor DAC is also introduced as complementary to the new quantizer...

in this paper, we give a characterization of strongly jordan zero-product preserving maps on normed algebras as a generalization of  jordan zero-product preserving maps. in this direction, we give some illustrative examples to show that the notions of strongly zero-product preserving maps and strongly jordan zero-product preserving maps are completely different. also, we prove that the direct p...

let g be a simple connected graph. the generalized polarity wiener index ofg is defined as the number of unordered pairs of vertices of g whosedistance is k. some formulas are obtained for computing the generalizedpolarity wiener index of the cartesian product and the tensor product ofgraphs in this article.

N papers have been pub­ lished on the repair of circumscribed defects in a number of bones of experi­ mental animals (Melcher and Irving 1962; Kramer, Killey and Wright 1968; Agsen 1968). The repair of extraction wounds in the jaws of experimental animals has also been extensively studied (Huebsch et al 1952; Boyne and Kruger 1962; Pietrokovski 1967; Tudo 1968; Huebsch and Hansen 1969; Mesrobia...

This review is atypical by design. It has used a synthesis of the available literature relating to the aetiology of AIS to draw attention to the lack of progress in this area despite intensive research for more than 100 years. The review has argued that if progress is to be made in this area then significant changes in approach to the problem must be made. Such changes have been outlined and ma...

Having lived originally in two remote Labrador communities, Katherine did not grow up wanting to be a nurse; in fact, such a career never once entered her mind! The opportunity to apply to nursing school was happenstance but thankfully, she grabbed the chance and came to realize the gift of helping others. This enthusiasm propelled her into a leadership role after just a few months of becoming ...

Proton transfer in protic ionic liquids is poorly understood. Some acid/base proton transfer reactions do not proceed to the extent that is expected from Delta pK(a)(aq) data from aqueous solutions, yet some do. In this work we have investigated protic ionic liquids obtained by proton transfer from a common acid, acetic acid, to a range of amine bases of similar pK(a)(aq) values. Probe indicato...

In medicine, law, consulting, and many other careers, a significant proportion of human capital is created through industry-specific learning-bydoing. In the absence of long-term wage contracts, if learning effects are sufficiently large, then young workers should face a negative wage in return for high future wages. However, if workers are liquidity constrained, then young workers compete away...

zur Erlangung des akademischen Grades d o c t o r r e r u m n a t u r a l i u m ii Acknowledgment I would like to thank my supervisor, Prof. Walden, for the opportunity to work and complete my PhD in his lab. I would like to thank you for encouraging my research and allowing me to grow as a research scientist. Without your supervision and guidance, this dissertation would not have been possible...
