The fine structure map of the yeast URA 3 gene was established by meiotic recombination, and amber nonsense mutations were located at different points on the map. The effect of the length of the labeling time on the specific radioactivity of ura 3 messenger RNA and on its repartition between poly(A)-RNA and RNA not containing poly(A) has been followed in nonsense mutants. Nonsense mutations red...

Measurement of uronic acids (URAs) which are a group of acidic sugar, would be useful for the understanding of dynamics of bacterial extracellular polymeric substances (EPS) in marine environments. However, the URA analysis using traditional hydrolysis method which is used for neutral sugar analysis poses serious problems in URA that is unstable under hydrolysis. We developed the methanolysis m...

The objective of this pilot study was to determine the effect of 6 different abdominal exercises on the electrical activity of the upper rectus abdominis (URA) and lower rectus abdominis (LRA). Eight healthy, adult volunteers completed 6 random abdominal exercises: curl up, Sissel ball curl up, Ab Trainer curl up, leg lowering, Sissel ball roll out, and reverse curl up. Action potentials were r...

In this study, a mixed massive random access scheme is considered where part of users transmit both common information and user-specific information, while others only information. scheme, transmitted by index modulation (IM)–aided unsourced (URA), IM-aided sourced (SRA). Practically, URA partitions channel blocks one transmission frame into multiple groups then employs the IM principle to acti...

Unsourced random access (URA) is a recently proposed multiple paradigm tailored to the uplink channel of machine-type communication networks. By exploiting strong connection between URA and compressed sensing, massive problem may be cast as sensing (CS) problem, albeit one in exceedingly large dimensions. To efficiently handle dimensionality coded (CCS) has emerged pragmatic signal processing t...

In the previous semester, we considered some fundamental ideas in the theory of group representations over finite fields. Specifically, we studied Norton's Irreducibility Criterion and Parker's Meat-Axe algorithm, two tools for investigating the reducibility of a representation. Given these tools, we wish to consider the more complicated problem of finding all subrepresen-tations of a group rep...
