Free-running enzymatic oligonucleotide synthesis for data storage applications [article]

Michael Anthony Jensen, Peter Griffin, Ronald W Davis
2018 bioRxiv   pre-print
Here we present preliminary results for a method of oligodeoxynucleotide synthesis using terminal deoxynucleotidyl transferase (TdT) to generate mixed base homopolymer runs of defined sequence. In a process we have termed Free-Running Synthesis (FRS), we allow TdT to freely add multiple bases of a given monomer. With this method, homopolymeric runs can be used for writing DNA in a data storage capacity, where a stretch of As, for example, will be read as a single base, and the transitions
more » ... n successive homopolymer runs encodes information. As a proof-of-concept, we demonstrate homopolymer additions of A, C and T onto the 3 prime end of a 22 base initiator strand.

The covering lemma for K

Tony Dodd, Ronald Jensen
1982 Annals of Mathematical Logic  
This paper is a continuation of [3] and. presupposes the results proved there. The main theorem of this paper is Th,zorem 5.17, the co"exing lemma for K, which asserts thttt, provided that there is no inner model with a measurable cardinal, then for every uncountable X tl~ere is Ye K with X= Y and X _c y. The reader will reeog~'~ise that this is an adap:afion of the covering lemma for L, and, indeed, that ff K should chance to be L (which happens precisely when 0 # does not exist) then tlqs

DoddRJense~ L[U, C] involves more work than we had realised; in the interests of [,re,5~zeing an accoant of the main result as speedily as possible ~ it is now t~ve yea~s since it was proved~we have decided to pre,~ent these last two results in a .3eparate paper "The covering lemma for L[U]".

Physically based modeling and animation of fire

Duc Quang Nguyen, Ronald Fedkiw, Henrik Wann Jensen
2002 ACM Transactions on Graphics  
We present a physically based method for modeling and animating fire. Our method is suitable for both smooth (laminar) and turbulent flames, and it can be used to animate the burning of either solid or gas fuels. We use the incompressible Navier-Stokes equations to independently model both vaporized fuel and hot gaseous products. We develop a physically based model for the expansion that takes place when a vaporized fuel reacts to form hot gaseous products, and a related model for the similar

The hot gaseous products, smoke and soot rise under the influence of buoyancy and are rendered using a blackbody radiation model. We also model and render the blue core that results from radicals in the chemical reaction zone where fuel is converted into products. Our method allows the fire and smoke to interact with objects, and flammable objects can catch on fire.

Time-dependent perturbation theory for nonequilibrium lattice models

Ronald Dickman, Iwan Jensen
1991 Physical Review Letters  
We develop a time-dependent perturbation theory for nonequilibrium interacting particle systems. We focus on models such as the contact process which evolve via destruction and autocatalytic creation of particles. At a critical value of the destruction rate there is a continuous phase transition between an active steady state and the vacuum state, which is absorbing. We present several methods for deriving series for the evolution starting from a single seed particle, including expansions for

Algorithms for computer generation of the various expansions are presented. Rather long series (24 terms or more) and precise estimates of critical parameters are presented.

Optimizing stringency for expression microarrays

James E. Korkola, Anne L.H. Estep, Sunanda Pejavar, Sandy DeVries, Ronald Jensen, Frederic M. Waldman
2003 BioTechniques  
While several studies have reported methods to optimize expression microarray protocols, none have dealt directly with hybridization wash stringency. We designed a series of experiments to determine the optimal stringency conditions for microarray experiments, using reproducibility and magnitudes of log 2 (test/reference) ratio values as measures of quality. Low-stringency wash conditions of cell line hybridizations led to nonspecific binding, resulting in increased intensities, decreased
more » ... ude of ratios, and poor reproducibility. Relatively high-stringency wash conditions were found to give the best reproducibility and large magnitude ratio changes, although increasing the stringency beyond this point led to lower magnitude ratios and poorer reproducibility. The expression levels of the ERBB2 oncogene in the BT474 versus MCF7 cell lines showed that high-stringency wash conditions gave the best agreement with real-time quantitative PCR, although the magnitude of the changes by microarray was smaller than for real-time quantitative PCR. Analysis of a series of cell lines washed at the optimized stringency indicated that the rank order of relative expression levels for ERBB2 microarray clones agreed well with the rank order of ERBB2 levels, as measured by quantitative PCR. These results indicate that the optimization of stringency conditions will improve microarray reproducibility and give more representative expression values.
