Numerical simulations are made for forced turbulence at a sequence of increasing values of Reynolds number Re keeping fixed a strongly stable, volume-mean density stratification. At smaller values of Re, the turbulent velocity is mainly horizontal, and the momentum balance is approximately cyclostrophic and hydrostatic. This is a regime dominated by so-called pancake vortices, with only a weak ...

Pancake flipping, a famous open problem in computer science, can be formalised as the problem of sorting a permutation of positive integers using as few prefix reversals as possible. In that context, a prefix reversal of length k reverses the order of the first k elements of the permutation. The burnt variant of pancake flipping involves permutations of signed integers, and reversals in that ca...

By measuring the Josephson Plasma Resonance, we have probed the influence of an in-plane magnetic field on the pancake vortex correlations along the c-axis in heavily underdoped Bi2Sr2CaCu2O8+δ (Tc = 72.4 ± 0.6 K) single crystals both in the vortex liquid and in the vortex solid phase. Whereas the in-plane field enhances the interlayer phase coherence in the liquid state close to the melting li...

Oral mite anaphylaxis is a new syndrome characterized by severe allergic symptoms occurring immediately after eating foods made with mite-contaminated wheat flour. This syndrome, which is more prevalent in tropical environments, is triggered more often by pancakes, and for that reason, it has been designated "the pancake syndrome." Because cooked foods are able to induce the symptoms, it has be...

The rapid detachment of liquid droplets from engineered surfaces in the form complete rebound, pancake bouncing, or trampolining has been extensively studied over past decade and is practical importance many industrial processes such as self-cleaning, anti-icing, energy conversion, so on. spontaneous needs an additional low-pressure environment manifestation bouncing on superhydrophobic require...

In this paper, we consider the lengths of cycles that can be embedded on edges generalized pancake graphs which are Cayley graph symmetric group S(m,n), generated by prefix reversals. The S(m,n) is wreath product cyclic order m and n!. Our main focus underlying undirected graphs, denoted Pm(n). cases when has one or two elements, these isomorphic to burnt respectively. We prove three P3(n) all ...
