Let G = (V, E) be a simple graph. A vertex labeling f : V → {0, 1} induces a partial edge labeling f ∗ : E → {0, 1} defined by f ∗(uv) = f(u) 84 KWONG, LEE, LO, SU AND WANG if and only if f(u) = f(v). For i = 0, 1, let vf(i) = |{v ∈ V : f(v) = i}|, and ef (i) = |{e ∈ E : f ∗(e) = i}|. A graph G is uniformly balanced if |ef (0)−ef (1)| ≤ 1 for any vertex labeling f that satisfies |vf(0)−vf (1)| ...

We consider local and global combinatorial constraints on embeddings of a simple closed curve in a rectangular array of unit squares in which the curve lies entirely within the rectangular array and passes through each unit square once. Geographical terminology is convenient to describe the embeddings. We study shortest segments of the embedded curve with no clockwise quarter turns (bays) and a...

The phenomenon of corruption in the Peoples Republic of China has recently gained more attention in the public discussion, as the media have reported more intensively on cases of exposed corruption, associated arrests, court sentences and even executions. Many have the impression that the extent of corruption in China has increased dramatically, but this conclusion is not warranted. The phenome...

Received July 10, 2002 Abstract Urea breath test (C-UBT) is a non-invasive diagnostic test for Helicobacter pylori infection. A preliminary retrospective study was conducted in the use of C-UBT in paediatric patients in Hong Kong. The study was conducted in Kwong Wah Hospital, a regional public hospital in urban Hong Kong. Eight asymptomatic paediatric patients who underwent C-UBT were analyzed...

We investigate an efficient quantum error correction of a fully correlated noise. Suppose the noise is characterized by a quantum channel whose error operators take fully correlated forms given by σ x , σ ⊗n y and σ ⊗n z , where n > 2 is the number of qubits encoding the codeword. It is proved that Email addresses: [email protected] (Chi-Kwong Li), [email protected] (Mikio Nakahara), yt...

the equation of state soave-redlich-kwong (srk) and its modification (predictive srk or psrk) are applied to simulate multicomponet distillation, which separate main component of spearmint essential oil. the simulation model is based on bubble point method, and the wang-henke algorithm. spearmint essential oil is considered in the study and the original experimental data were obtained from pilo...
