Peridocity, Change Detection And Prediction In Microarrays, Mohammad Shahidul Islam
Digitized Theses
Three topics in the analysis of microarray genomic data are discussed and improved statistical methods are developed in each case. A statistical test with higher power is developed for detecting periodicity in microarray time series data. Periodicity in short series, with non-Fourier frequencies, is detected through a Pearson curve calibrated to the null distribution obtained by computer simulation. Unlike other traditional methods, this approach is applicable even in the presence of missing values or unequal time intervals. The usefulness of the new method is demonstrated on simulated series as well as actual microarray time series.
The second topic develops a …
Palaeoecology Of The Middle Cambrian Raymond Quarry Fauna, Burgess Shale, British Columbia, Matthew Galen Devereux
Palaeoecology Of The Middle Cambrian Raymond Quarry Fauna, Burgess Shale, British Columbia, Matthew Galen Devereux
Digitized Theses
An assemblage if over 9000 systematically collected fossils from the Middle Cambrian Burgess Shale was analyzed in order to resolve the palaeoecology. Sediment and fossil evidence both show that the constituent fauna was largely autochthonous. The 'standing crop' of organisms preserved with each burial event was affected by variable taphonomic factors both laterally and temporally, but information loss appears to have been minimized. An autecological review of the trophic nucleus provides new insights with regard to behavior of the organisms, including life habits and feeding strategies. Unlike their modern representatives, priapulid worms (or at least Ottoia) appear to have …
The Renner Monoids And Cell Decompositions Of The Classical Algebraic Monoids, Zhenheng Li
The Renner Monoids And Cell Decompositions Of The Classical Algebraic Monoids, Zhenheng Li
Digitized Theses
The Renner monoids, cross section lattices and cell decompositions of the classical algebraic monoids are studied.
The Renner monoid is extremely important in the theory of reductive algebraic monoids. It is well know that the Renner monoid [Special characters omitted.] of Mn (K ) is the monoid of all zero-one matrices which have at most one entry equal to one in each row and column, i.e., [Special characters omitted.] consists of injective partial maps on a set of n elements. We obtain that the Renner monoids of the symplectic algebraic monoids and special orthogonal algebraic monoids turn out …
Orbit Structure Of Finite And Reductive Monoids, Zhuo Li
Orbit Structure Of Finite And Reductive Monoids, Zhuo Li
Digitized Theses
A reductive monoid is an algebraic monoid with a reductive unit group. We introduce a new class of reductive monoids, $({\cal T}, \sigma)$-irreducible monoids. Generally, we have the question of finding the orbits of the unit group of a reductive monoid acting on both sides of the monoid. Putcha and Renner give a recipe to determine the orbits for ${\cal T}$-irreducible monoids. Motivated by their construction of finite reductive monoids, the concept of (${\cal T}, \sigma)$-irreducible monoid arises naturally.
We obtain that the ${\cal T}$-irreducible monoids turn out to be a special class of the $({\cal T}, \sigma)$-irreducible monoids. We …
