A long range frustration index R is introduced to the finite connectivity Viana–Bray ±J spin glass model as a new order parameter. This order parameter is then applied to the random K-satisfiability (K-SAT) problem to understand its satisfiability transition and to evaluate its global minimum energy. Associated with a jump in R from zero to a finite value, SAT-UNSAT transition in random 3-SAT o...

Rattans (subfamily Calamoideae) are an important component of the forests of the Old World. However, few studies have been conducted on the distribution of these abundant palms within different habitats, specifically in Peninsular Malaysia. This study was aimed at assessing rattan diversity, abundance and biomass change across two different habitat types, namely, dipterocarp forests and fresh-w...

The iodate reduction by hydrogen peroxide in acidic solutions is part of the Bray-Liebhafsky and Briggs-Rauscher oscillating reactions. At low hydrogen peroxide concentrations, typical of the Bray-Liebhafsky reaction, its rate law is -d[IO(-)(3)]/dt = (k'(R) + k"(R)[H(+)])[IO(-)(3)][H(2)O(2)] with k'(R) = 1.3 × 10(-7)(20°), 7.8 × 10(-7) (39°), 1.4 × 10(-5) M(-1) s(-1) (60°) and k"(R) = 1.5 × 10...

ISSUES Many policy review articles have concluded that alcohol screening and brief intervention (SBI) is both cost-effective and cost-beneficial. Yet a recent cost-effectiveness review for the United Kingdom's National Institute for Health and Clinical Excellence suggests that these conclusions may be premature. APPROACH This article offers a brief synopsis of the various types of economic an...

Identification of trends and their correspondence with dynamical state transitions are briefly discussed on several reaction network models. The nfluence of different threshold values on the trend analysis and dynamical state analysis results is examined. Both methods are applied here to he results of the numerical simulation. For this purpose the models of three reaction systems are used: simp...
