– the normal and lateral line cycloid scales of a cyprinid fish capoeta damascina (valenciennes incuvier and valenciennes, 1842) have been subjected to the scanning electron microscopy technique in orderto study their detailed structure. the scales have the general morphological characteristics of the cycloidscales. in the normal scale located below the dorsal fin, the focus lies towards the an...

A new approach for fabricating a series of multi-functional honeycomb-patterned films was successfully achieved using ionomers via breath figures.

The development of new models of biological tissues that consider cells in a discrete manner is becoming increasingly popular as an alternative to continuum methods based on partial differential equations, although formal relationships between the discrete and continuum frameworks remain to be established. For crystal mechanics, the discrete-to-continuum bridge is often made by assuming that lo...

The large development of wireless services and the scarcity of the usable frequencies require an efficient use of the radio spectrum which guarantees interference avoidance. The channel assignment problem (CAP) achieves this goal by partitioning the radio spectrum into disjoint channels, and assigning channels to the network base stations so as to avoid interference. On a flat region without ge...

I. Honeycombs. The honeycomb of the bees is a loose tissue of wax forming a plane layer. The first things on it which catch one's eye are the regular hexagonal patterns on both sides. The hexagons are the openings of prismatic vessels, called bee-cells. Kepler described the shape of the bee-cells more fully. It turned out that the bottom of a cell consists of three equal rhombi as shown in Figu...

Recently, Duminil-Copin and Smirnov proved a long-standing conjecture by Nienhuis that the connective constant of self-avoiding walks on the honeycomb lattice is

The critical temperature of layered Ising models on triangular and honeycomb lattices are calculated in simple, explicit form for arbitrary distribution of the couplings.

We study the q-state Potts antiferromagnet with q = 3 on the honeycomb lattice. Using an analytic argument together with a Monte Carlo simulation, we conclude that this model is disordered for all T ≥ 0. We also calculate the ground state entropy to be S0/kB = 0.507(10) and discuss this result. ∗email: shrock@insti.physics.sunysb.edu ∗∗email: tsai@insti.physics.sunysb.edu The effect of ground s...

We study a classical fully-frustrated honeycomb lattice Ising model using Markov chain Monte Carlo methods and exact calculations . The Hamiltonian realizes a degenerate ground state manifold of equal-energy states, where each hexagonal plaquette of the lattice has one and only one unsatisfied bond, with an extensive residual entropy that grows as the number of spins N . Traditional singlespin ...
