Multiplicative ambiguity

An important issue needs to be discussed next. Multiplying a column of C with any number and its corresponding row of A with the inverse of that number, does not affect the product CA and thus this factor is not determined at all. It can be freely chosen. Due to this multiplicative ambiguity, only the shapes of the concentration profiles (and component spectra) can be determined by any model-free method and only additional quantitative information allows the absolute determination of C and A. 

If metadata are predefined for a workspace or on file-type level, the user is prompted for entering missing metadata, either entered manually or via selection from a pick list. Predefined pick lists help to avoid misspellings, multiple ambiguous definitions. 

Before quantitative evaluation, the events must be coded with an unique ideniitier. A systematic and orderly identification scheme minimizes the possibility of ambiguity or multiple identifier for the same event. 

The magnetic field seen by the probe neutron is solely due to the magnetic dipole moment density of the unpaired electrons. In other words, the magnetisation density is simply related to the electron spin density by a multiplicative factor, and there is no ambiguity in its definition. 

NPV does not require that the total lives (or multiples thereof) of projects be equal for a comparison to be made. Thus, ambiguous and sometimes contradictory results can arise in using IRR versus NPV [Brigham (1982), Woinsky (1996)]. Jelen and Black (1983) have suggested a comparison based on uniform annual cost, called unacost. 

Here we extend the bistatic case to netted scenarios. The topology selected is the simple case of N transmitters and one common receiver, i.e. we have in effect a series of multiple bistatic geometries with varying baselines. The reason for this choice lies in the fact that it is convenient to reference all calculations to the single receiver, thus obtaining one unified form for the ambiguity function. 

Avoid ambiguous language Don t use words whose multiple meanings may cause confusion be certain the order of words in your sentences conveys the meaning you intend. 

The role of PARP-1 as a modulator of chromatin stiucture, as well as its chromatin-dependent effects on transcription, has been well established in the literature (D Amours et al, 1999 Kraus and Lis, 2003 Rouleau et al, 2004 Kim et al, 2005). In this section, we will highlight some of the historical studies, as well as more recent studies, that have characterized the role of PARP-1 and PAR in these processes. Note that, when describing this work, the term PARP in the absence of any additional identifiers refers to PAR-generating proteins of ambiguous identity (e.g., as in early studies, which were conducted without the knowledge that multiple PARP family members exist, or when multiple splice variants of a PARP-1-like protein exist in a single organism, as in Drosophila). 

Apparently, the criterion (12.27) does not provide the complete understanding of the phenomenon. There is no evidence of the effect of multiple variables on flame stability mentioned in section 12.1. Moreover, the physical grounds for estimating the characteristic times tr and tc entering the Dunskii s criterion remain unclear. Therefore the interpretation of tr and tc in the relevant literature is quite ambiguous.
