The thesis aims at extending the capabilities of devices and enabling cooperation, i.e., data connection sharing, among users who may or may not necessarily be related to or know each other. To achieve this objective as well as to validate the results of our theoretical analysis, we developed a smart-phone application for data connection sharing. By means of data connection sharing, users may i...

Solution: The ring F [x] of polynomials with coefficients in a field F is a P.I.D. Each prime ideal is generated by a monic, irreducible polynomial. Assume there are only a finite number of prime ideals generated by the polynomials f1, . . . , fn and let f(x) = 1+f1(x) · · · fn(x). No fi divides f , hence f is also irreducible. This contradicts the assumption that all the prime ideals were gene...

Accumulating evidence argues that aging exerts a profound influence on epigenetics, and vice versa. A pair of studies by Merkwirth et al. and Tian et al. now provide insights on how mitochondrial stress experienced by C. elegans larvae propagates a specific and persistent epigenetic response that protects adult cells and extends lifespan.

Full points can be obtained for correct answers to 8 questions. Each numbered question (which may have several parts) is worth 20 points. All answers will be graded, but the score for the examination will be the sum of the scores of your best 8 solutions. Algebra A1. (a) State the Class Equation.

A recent increase in the number of masters athletes in the United States can be attributed to a growing population of more than 300 million people, an aging subpopulation of “baby boomers,” and a culture enamored with sports. To exemplify this increase, in 1987, the first National Senior Games had 2500 participants (all older than 50 years), which more than quadrupled to 10,100 participants in ...

Sex determination offers an opportunity to address many classic questions of developmental biology. In addition, because sex determination evolves rapidly, it offers an opportunity to investigate the evolution of genetic hierarchies. Sex determination in Drosophila melanogaster is controlled by the master regulatory gene, Sex lethal (Sxl). DmSxl controls the alternative splicing of a downstream...

some months ago published a series of Illustrations of Regional Anatomy of the human body, exclusive of the limbs. This Journal, in reviewing this work, expressed regret that the limbs had not been included in what was otherwise an admirable work. This defect has now been remedied by the present publication of two new parts to illustrate their dissection. We can add nothing further to our notic...
