Sentence examples for internal periodicity from inspiring English sources

Amino acid insertions or deletions in protein regions that are supposed to form a alpha helix can have a great impact on the helical structure, since they are likely to destroy the internal periodicity of the helix.

Moving on to the specifics of the Fibonacci-like iteration coincidence, we would like to touch briefly on the following two aspects: First, the internal periodicity of tRNA sequences and certain other considerations suggest to many investigators that tRNA precursors were at first much shorter (why would they be longer?), but have grown afterwards.

As a consequence, the 76-nt long cloverleaf would have internal sequence periodicity the hallmark of tRNAs reported long ago ([ 44], see also [ 35]).

In their long evolutionary history, unicellular and multicellular organisms have pursued the two divergent, although complementary, goals of matching the time dependencies of their internal environments with the periodicities of the external world (i.e. the elaboration of annual, seasonal, daily and tidal rhythms), and optimizing for tolerance to external perturbation [1], [2], [3], [4], [5].

When a test data set is generated from the TDS-1 magne-tospheric reference model using only the degree 1 internal and external coefficients, the periodicity is much reduced (Fig. 7, bottom).

Starting from the observation that a continuous grid preserves the periodicity of the internal masonry layer, rigid-plastic homogenization is applied directly on a multi-layer heterogeneous representative element of volume (REV) constituted by bricks, finite thickness mortar joints and external FRP grids.

The apolar core lipids of LDL consist mainly of cholesteryl esters (40% or more of particle mass) and triglycerides (5% or less of particle mass), which show a well-defined internal layer-structure with a periodicity of about 3.6 nm below the melting temperature.

Notably, there are internal modes at the same period as the solar 27-day periodicity which adds to the complexity.

The diffraction pattern consists of a periodic distribution with a periodicity reciprocally related to the raster periodicity.

Environmental periodicity creates the need for organisms to develop a sense of internal time, and thus biological clocks have evolved a range of internal time-keeping mechanisms that generate circadian, ultradian or infradian rhythms.

In this study we instead acknowledged that different synchronization methods may correspond to different environments (internal and/or external) in which the cells propagate, and sought to explain why genes have different expression patterns with respect to periodicity under these conditions.
