Phase retrieval algorithms: a comparison

by J. R. Fienup - Appl. Opt , 1982
"... Iterative algorithms for phase retrieval from intensity data are compared to gradient search methods. Both the problem of phase retrieval from two intensity measurements (in electron microscopy or wave front sens-ing) and the problem of phase retrieval from a single intensity measurement plus a non- ..."

2005 A Pliocene-Pleistocene stack of 57 globally distributed benthic ?18O records. Paleoceanography 20: PA1003

by Lorraine E. Lisiecki, Maureen E. Raymo - Holocene development of the Yellow River's subaqueous delta, North Yellow Sea. Marine Geology , 2005
"... [1] We present a 5.3-Myr stack (the ‘‘LR04’ ’ stack) of benthic d 18 O records from 57 globally distributed sites aligned by an automated graphic correlation algorithm. This is the first benthic d 18 O stack composed of more than three records to extend beyond 850 ka, and we use its improved signal ..."

Finally, the relative phases of the stack’s 41- and 23-kyr components suggest that the precession component

Functional genomics: expression analysis of Escherichia coli growing on minimal and rich

by Han Tao, Christoph Bausch, Craig Richmond, Frederick R. Blattner, Tyrrell Conway , 1999
"... DNA arrays of the entire set of Escherichia coli genes were used to measure the genomic expression patterns of cells growing in late logarithmic phase on minimal glucose medium and on Luria broth containing glucose. Ratios of the transcript levels for all 4,290 E. coli protein-encoding genes (cds) w ..."

Towards Requirements-Driven Information Systems Engineering: The Tropos Project

by Jaelson Castro, Manuel Kolp, John Mylopoulos - INFORMATION SYSTEMS , 2002
"... Information systems of the future will have to perform well within ever-changing organizational environments. Unfortunately, existing software development methodologies (object-oriented, structured or otherwise) have traditionally been inspired by programming concepts, not organizational ones, leadi ..."

#ers the notions of actor, goal and (actor) dependency, and uses these as a foundation to model early and late requirements, architectural and detailed design. The paper outlines Tropos phases through an e-business example, and sketches a formal language which underlies the methodology and is intended to support

The MODIS cloud products: Algorithms and examples from Terra

by Steven Platnick, Michael D. King, Steven A. Ackerman, W. Paul Menzel, Bryan A. Baum, Jérôme C. Riédi, Richard A. Frey - IEEE Transactions on Geoscience and Remote Sensing , 2003
"... (MODIS) is one of five instruments aboard the Terra Earth Observing System (EOS) platform launched in December 1999. After achieving final orbit, MODIS began earth observations in late February 2000 and has been acquiring data since that time. The instrument is also being flown on the Aqua spacecraf ..."

a) . Factors influencing the early phases of growth of Aerobacter aerogenes

by S. Dagley, E. A. Dawes, G. A. Morrison - J . gen. Microbiol , 1950
"... SUMMARY: The method used in maintaining cultures of Aerobacter m o g m s affects the relationship between duration of lag phase and age of inoculum in a gludose ammonium salt medium. Organisms kept in broth may show pronounced early lag whilst those from agar slopes do not. Previous subcultivation w ..."

Approach to Equilibrium of Glauber Dynamics In the One Phase Region. II: The General Case

by F. Martinelli, E. Olivieri , 1994

We develop a new method, based on renormalization group ideas (block decimation procedure), to prove, under an assumption of strong mixing in a finite cube o , a Logarithmic Sobolev Inequality for the Gibbs state of a discrete spin system. As a consequence we derive the hypercontractivity of the ..."
