A new premixed turbulent combustion model is proposed, which based on one-dimensional (1D) filtering of density times progress variable and reaction source term laminar flame profiles using a filter kernel that reflects the variation area planar fronts moving through volumes. It shown these genuinely multidimensional effects qualitatively change relation between filtered Favre-filtered compared...

Classical or transmission genetics is the study of patterns of inheritance: how traits in an organism – and, either implicitly or explicitly, the genes that give rise to those traits – are passed from one generation to the next. For most undergraduate students, their fi rst (and sometimes only) experience of the study of inheritance is bound up with Mendelian principles. Anyone who has studied ...

Wrinkled morphology is a distinctive phenotype observed in mature biofilms produced by a great number of bacteria. Here we study the formation of macroscopic structures (wrinkles and folds) observed during the maturation of Bacillus subtilis pellicles in relation to their mechanical response. We show how the mechanical buckling instability can explain their formation. By performing simple tests...

The effect of resonant temporal forcing on a system undergoing a Hopf bifurcation with D4 (square) symmetry is studied. The forcing breaks the continuous normal form symmetry of the governing amplitude equations, but the D4 symmetry is preserved. For this system, it is shown that bursts with very large dynamic range may occur. The bursts are associated with visits near solutions “at infinity”, ...

Solvothermal reactions of Cd(OAc)2/Zn(OAc)2 with a new ligand, (pyridin-3-yl)methyl 4-(2-(4-((pyridin-3-yl)methoxy)phenyl)diazenyl)benzoate (L1), under different templates via an in situ ligand transformation reaction produced five coordination polymers, [CdL2(H2O)]n (1), [Cd1.5L3]n (2), [Cd2L4]n (3), [(ZnL2)·H2O]n (4) and {[Zn(1,3-BDC)(L1)]·MeCN·0.5H2O}n (5), where HL = 4-(2-(4-((pyridin-3-yl)...
