This paper considers the galvanic distortion caused only by small-scale heterogeneities (smaller than the typical site spacing and confined within a near-surface layer shallower than the inductive scale length of interest).
Science
The main purpose of this series of experiments is the study of the rapid inversion (almost 50% of the jet over the length of interest) seen in previous experiments.
The solution of this problem is not straightforward because MT data on land are usually affected by galvanic distortion, i.e., an alteration in the MT impedance due to near-surface small-scale heterogeneity that is smaller than a typical site spacing and confined to be shallower than the inductive scale length of interest (Ledo et al. 1998; Utada and Munekane 2000; Bibby et al. 2005).
Science
Second, the number of heterozygous SNPs allowed should be determined separately for each ROH length of interest and for each SNP density, as suggested here.
The 292 bp fragment in length of interest was then sliced cleanly under UV illumination, and recovered by using MagExtractor® DNA Fragment Purification Kit (TOYOBO Co., Ltd. Osaka, Japan).

Science
This model applies to a wide range of transport regimes, characterized by a wide range of Knudsen numbers as a function of pressure and length scale of interest.

In the case of characterization of bacteria on growth media using light scattering the length scales of interest can be classified as micro-scale (single bacterium), macro-scale (bacterial colonies of more than 1012 bacterium that have passed through the exponential growth phase and reached mm size), and the intermediate or meso-scale of several tens of hundreds of bacteria.
We regard it as realistic in traffic flow models that drivers keep watching their close environment and, this can be modelled in terms of a convolution operator, which need not be symmetric in space and which can have a small support in comparison with the length scale of interest.
Expert writing Tips
Best practice
When using "length of interest" in scientific writing, clearly define the specific units of measurement (e.g., time, distance, sequence length) to avoid ambiguity.
Common error
Avoid using "length of interest" without specifying what 'interest' refers to. Always provide context to clarify the relevance of the length being discussed.
