Carman, William, 1790-1841 (Mss 52), Manuscripts & Folklife Archives

MSS Finding Aids

Ciphering books (2) of William Carman, a teacher in Mayfield, Kentucky. One book is dated 1815-1816; the other one is undated, but evidently of the same period. The ciphering used is the British pound system. The title page of one volume is by Gavin G. Craig of WKU's Penmanship Department.


At Least Four Distinct Circadian Regulatory Mechanisms Required For All Phases Of Rhythms In Mrna Amount, Sigrid Jacobshagen, Bruce Kessler, Claire Rinehart Jul 2008

At Least Four Distinct Circadian Regulatory Mechanisms Required For All Phases Of Rhythms In Mrna Amount, Sigrid Jacobshagen, Bruce Kessler, Claire Rinehart

Mathematics Faculty Publications

Since the advent of techniques to investigate gene expression on a large scale, numerous circadian rhythms in mRNA abundance have been reported. These rhythms generally differ in amplitude and phase. First studies on circadian rhythms of transcription on a large scale are also emerging. We investigated to what extent the same circadian regulatory mechanism of transcription can give rise to rhythms in RNA amount that differ in phase solely based on a parameter that is not regulated by the circadian clock. Using a discrete-time approach, we modeled a sinusoidal rhythm in transcription with various constant exponential RNA decay rates. We …

Calculus Of Variations On Time Scales And Its Applications To Economics, Chris Mcmahon May 2008

Calculus Of Variations On Time Scales And Its Applications To Economics, Chris Mcmahon

Masters Theses & Specialist Projects

The goal of time scale research is to progress the development of a harmonized theory that is all encompassing of the more commonly known specialized forms. The main results of this paper is the presentation of the Ramsey model which can be written using both the A and V operators, and solved using the two separate theories of the calculus of variations on time scales. The next presentation will be of the solution of an adjustment model, for a specific form of a time scale, whose functional can only be optimized, using the existing theory, when written with the A …
