The maximum entropy method (MEM) is an information-theory-based technique that was first developed in the field of radioastronomy to enhance the information obtained from noisy data (Gull and Daniell 1978). The theory is based on the same equations that are the foundation of statistical thermodynamics. Both the statistical entropy and the information entropy deal with the most probable distribution. In the case of statistical thermodynamics, this is the distribution of the particles over position and momentum space ( phase space ), while in the case of information theory, the distribution of numerical quantities over the ensemble of pixels is considered. 

This technique, called site-directed mutagenesis, is one of the most important in modern genetics and biochemistry. The first site-directed mutagenesis studies were carried out by David Shortle and Daniel Nathans in 1978 with the help of the mutagen sodium bisulfite, which deaminates C residues so that they become converted into U residues. 

In September 1994, the NMSHTD retained a second consultant, Daniel B. Stephens Associates, Inc. (DBS A) to design and implement a corrective action system at the Artesia Patrol Yard. Sections 3.1 and 3.2 outline DBS A s rationale for and design of the high-vacuum SVE system for the Artesia Yard. The techniques used to enhance the recovery of petroleum vapors from the vadose zone are described in Sections 3.3 and 3.4. These techniques extended the operation of the high-vacuum SVE system and allowed a more effective cleanup of the vadose zone in preparation for the current phase of bioventing.

It is possible to design multipath control schemes in which the laser phase cancels out of the interference term. One possibility is a diamond path configuration, co + 0)2 vs 0)2 + o), with a resonance near o) contributing a phase to the first path and a resonance near 0)2 contributing a phase to the second path. As before, the total probability is the square of the sum of the amplitudes for each path, but here the phases of the two laser beams appear in both paths and cancel in the cross term. In this case the control parameters are the laser frequencies, which determine the detuning from the resonances. This technique was used by Daniel Elliott and coworkers to control the differential cross sections for the ionization of Ba and NO. 

Several approaches have been reported for the screening of polymerase activity, for example radioisotope assays such as scintillation proximity assays [56, 57] or fluorescence-based assays [58-61], Most of these assays, however, suffer from use of tedious procedures, the use of radioisotopes, or use of expensive reagents for fluorescence signal generation. A convenient means of online monitoring of DNA polymerase activity has recently been presented by Andreas Marx and Daniel Summerer [62]. Their technique involves a DNA template that forms a stable hairpin structure labeled at two positions ...

Nuclear Magnetic Resonance Concepts and Methods by Daniel Canet42 contains particularly clear presentations on techniques and data processing for Fourier transform NMR and related methods. Articles in the Encyclopedia of NMR on Fourier Transform Spectroscopy,43 Fourier Transform and Linear Prediction Methods, 39 and Maximum Entropy Reconstruction44 are also very informative. A Handbook of NMR includes a very clear description of the maximum entropy method and its limitations.19...
