Complete graphCycleKneser graphAn -labeling of a graph is a vertex labeling such that the difference of the labels of any two adjacent vertices is at least and that of any two vertices of distance is at least . The minimum span of all -labelings of is denoted by . Lin and Lam (...
A k-L(2,1)-labelling of a graph G is a mapping f:V(G)->{0,1,2,aEuro broken vertical bar,k} such that |f(u)-f(v)|a parts per thousand yen2 if uvaE(G) and f(u)not equal f(v) if u,v are distance two apart. The smallest positive integer k such that G admits a ...
The key feature of these libraries is usage of generalization of graph representation offered by B. G. Nickel et al. In this approach graph is represented in some unique 'canonical' form that depends only on its combinatorial type. The uniqueness of graph representation gives an efficient way ...
Spinal magnetic resonance (MR) scans are a vital tool for diagnosing the cause of back pain for many diseases and conditions. However, interpreting clinically useful information from these scans can be challenging, time-consuming and hard to reproduce ac
(u,v) = 2. The span offis the difference between the largest and the smallest numbers inf(V(G)). The λd,1-number ofGis the minimum span over allL(d, 1)-labellings ofG. For natural numbersnandk, wheren> 2k, a generalised Petersen graphP(n,k) is obtained by letting its ...

As with everything in the manufacturing process, there are always some variance between parts and images (spatial registration). We use an X,Y and angular micro-adjust, which allows for a respectable tolerance of 0.020" | 0.51mm, which is more than adequate for most applications. However, ...
Finally, we examined EU labelling in the cerebellum of two Purkinje cell-specific mutant mouse models for, respectively, a severe progeroid DNA repair deficiency syndrome (Ercc1d/fPcp2-Cre mice) [11] and spinocerebellar ataxia 1 (SCA1, ATXN1[82Q] mice) [7]. In both mouse models, we ...
All patients were free of DR during the first 5 years after surgery. Of these, 379 (55.7%) were premenopausal at diagnosis and 301 (44.3%) patients were postmenopausal. The patients' baseline demograph- ics are summarized in Table 1. The median age at diagnosis was 50.3 years; ...
