Given desired ancestry proportions α and β, the age n of the point admixture, and the number m of admixed individuals to simulate, we built each admixed chromosome as a composite of chromosomal segments from the source populations, choosing breakpoints via a Poisson process with rate constant n, and sampling blocks at random according to the specified mixture fractions.
The results suggest that shape variation in materials design, inspired by structural biological materials, can allow for tunable behavior in flexible composites made of segmented scale assemblies to achieve enhanced user mobility, custom fit, and flexibility around joints for a variety of protective applications.
Meanwhile, the failure modes of composite segments were investigated.
Thus, a circular chromosome is a composite of many small cylindrical segments each rotated around a center point in x, y, z space.
Scanning from the proximal promoter towards the distal sequences 3,000 bp homologue segments were evaluated allowing 500 bp overlap of segments at each composite model scanning step.
Such wounds require coverage via transposed or transplanted composite segments of skin, subcutaneous tissue, muscle, and, in some cases, bone and nerve.
None of the composite segments were contracted and the vascular pedicles were normal.
The test results confirm quite well results obtained from Ref. [Abosbaia, Mahdi and Hamouda. Axial quasi-static crushing behaviour of segmented composite tubes. Int. J. Compos. Struct. 2003; 60(3): 327–343] that considerable improvement with respect to stability in load-carrying capacity can be obtained.
Normal voiding was reestablished soon after surgery and examination of the reconstructed bladders after 3 mo demonstrated viable, vascularised, composite cystoplasty segments with no fibrosis or contraction.
The specimens were strengthened with external composite reinforcement – longitudinal segments of CFRP strips and transverse confinement executed with CFRP sheets.
Comparisons show that the finite element model is suitable for composite segments and predicts the behavior of composite segments accurately.
