It is shown that the percolation model of hydrogen-bonded crystals, which is a 6-vertex model with bond defects, is completely equivalent to an 8-vertex model in an external electric field. Using this equivalence we solve exactly a particular 6-vertex model with bond defects. The general solution for the Bethe-like lattice is also analysed.

Compartmental network modelling is compared with the bond graph approach. Whilst both approaches build on the conservation principle, the compartmental network approach is on a slightly higher level and more compact. Also no analogies must be used, the concepts of physics are used directly in connection whilst system theoretical arguments define consistency and solvability, being roughly equiva...

This study investigated the ability of One-Up Bond alone and mineral trioxide aggregate (MTA), with and without a secondary seal of One-Up Bond or SuperEBA to seal saucer-shaped perforation defects in human molars. Cusps were removed, roots were amputated, and endodontic therapy completed on 40 extracted teeth. A cylindrical hole was made in each tooth from the furcation area to the chamber, in...

We present an asymptotic solution for call options on zero-coupon bonds, assuming a stochastic process the price of bond, rather than interest rates in general. The bond incorporates dampening return volatility based maturity bond. derive PDE similar way to Black and Scholes. Using perturbation approach, we value option. result is interesting, as leading order terms are equivalent Black–Scholes...

We propose an approach to optimally select corporate bond portfolios based on bond-specific characteristics (maturity, credit rating, coupon, illiquidity, past performance, and issue size) and macroeconomic conditions (recessions and macroeconomic uncertainty measures). The approach relies on a parametric specification of the portfolio weights and allows us to consider a large cross-section of ...

In dynamic force spectroscopy, a (bio-)molecular complex is subjected to a steadily increasing force until the chemical bond breaks. Repeating the same experiment many times results in a broad distribution of rupture forces, whose quantitative interpretation represents a formidable theoretical challenge. In this study we address the situation that more than a single molecular bond is involved i...

statement of the problem: various methods such as light emitting diode (led) have been used to enhance the polymerization of resin-based orthodontic adhesives. there is a lack of information on the advantages and disadvantages of different light curing systems. purpose: the aim of this study was to compare the effect of led and halogen light curing systems on the shear bond strength of orthodon...

Simulators in power electronics are less developed than in other electronic fields. The main modelling methods are between the numerical simulation of semiconductor device equations that hardly simulate circuits, and equivalent circuit models that show poor accuracy. We propose the application of the bond graph techniques to model modular power semiconductor devices. Furthermore, the IGBT is a ...
