The disadvantage in producing the past tense of regular relative to irregular verbs shown by some patients with non-fluent aphasia has been alternatively attributed (a) to the failure of a specific rule-based morphological mechanism, or (b) to a more generalised phonological impairment that penalises regular verbs more than irregular owing to the on-average greater phonological complexity of re...

We study the diffusion equation with an appropriate change of variables. This is in general a partial differential (PDE). With self-similar and related Ansat\"atze we transform PDE to ordinary equation. The solutions belong family functions which are presented for case infinite horizon. In presentation accentuate physically reasonable solutions. also time dependent phenomena, where spreading ma...

Recently, various researches have revealed the importance of investigations performed for evaluating mechanical properties and damages brain tissues while dealing with production surgical ligaments helmets. Therefore, it is vital to study structure both experimentally numerically. By experimental tests, despite being costly, almost impossible establish stress distribution in micro scale, which ...

Vertices and symmetries of regular and irregular chiral polyhedra are represented by quaternions with the use of Coxeter graphs. A new technique is introduced to construct the chiral Archimedean solids, the snub cube and snub dodecahedron together with their dual Catalan solids, pentagonal icositetrahedron and pentagonal hexecontahedron. Starting with the proper subgroups of the Coxeter groups ...
