We discuss the current status of a computational approach which allows to evaluate the dielectric matrix, and hence electronic excitations like optical properties, including local field and excitonic effects. We introduce a recent numerical development which greatly reduces the use of memory in such type of calculations, and hence eliminates one of the bottlenecks for the application to complex...

Proof. As the edges in GC represent causal relations, a path of length 0 (no edge) is not considered a causal relation, and existence of a directed path from a variable back to itself would contravene the causal DAG assumption, hence: irreflexive and acyclic (or, more accurate, asymmetric). Transitivity follows immediately, by concatenation, from the sequence 〈X, .., Y, .., Z〉, in which each no...

Correlations in fluids in nonequilibrium steady states are long range. Hence, finite-size effects have important consequences in the nonequilibrium thermodynamics of fluids. One consequence is that nonequilibrium temperature fluctuations induce nonequilibrium Casimir-like pressures proportional to the square of the temperature gradient. Hence, fluctuations cause a breakdown of the concept of lo...

We show that the Gaussian Elimination algorithm can be proven correct with uniform Extended Frege proofs of polynomial size, and hence feasibly. More precisely, we give short uniform Extended Frege proofs of the tautologies that express the following: given a matrix A, the Gaussian Elimination algorithm reduces A to row-echelon form. We also show that the consequence of this is that a large cla...

Results: The mean GI was significantly higher in males (1.56 ± 0.31 mm) when compared to females (1.42 ± 0.34 mm). Hence the present sample was subjected to discriminant analysis with gender as a grouping variable, GI and GA as independent variables. Based on Wilk’s lambda values Gonial index (GI) was observed to provide better sex determination when compared to Gonial angle (GA). Hence 2 diffe...

Asian organic foods consumers’ behaviour is worth investigating to sustain the continuous growth of organic foods consumption. Hence, Fiona has the ambition to employ the innovation diffusion theory to profile and understand organic foods consumers in Hong Kong in her research proposal. The process of writing an acceptable research proposal is challenging, tedious and time consuming as depicted...

Acinetobacter spp. are Gram negative coccobacilli causing various nosocomial infections. They possess different types of Beta-lactamases like SHV, TEM and others which lead to treatment failure in case of infections due to this pathogen. Studying their species distribution in various infections and drug resistance pattern is hence important. Hence our study was aimed to study the different infe...

The existence of a series of problems in transportation management of public and personal vehicles causes to consider intelligent transportation systems. Hence, here we investigate to introduce and the performance of intelligent transportation system ITS which is among new technologies in information technology and at last the importance and necessity of lack of delay in data and informat...
