The paper is devoted to estimates of the spanning tree congestion for some planar graphs. The main results of the paper: (1) We almost determined (up to ±1) the maximal possible spanning tree congestion for planar graphs. (2) The value of congestion indicator introduced in Ostrovskii [Discrete Math. 310 (2010), no. 6–7, 1204–1209] can be very far from the value of the spanning tree congestion. ...

The quantum entanglement of amplitude and phase quadratures between two intense optical beams with a total intensity of 22 mW and a frequency difference of 1 nm, which are produced from an optical parametric oscillator operating above threshold, is experimentally demonstrated with two sets of unbalanced Mach-Zehnder interferometers. The measured quantum correlations of intensity and phase are i...

Extensive calculations for the vibrational band origins of D2H þ up to dissociation are presented. Due to the high density of vibrational states near dissociation, huge basis sets needed to be used as well as massively parallel computers. We have found 1209 A1 and 1078 B1 bound states, some of which display long-range features, which are analysed in detail. The calculations were performed withi...

Culture-independent detection tests (CIDTs) for Campylobacter have become an area of intense controversy and confusion among laboratorians in the field of clinical microbiology. To date, the true analytical and clinical performance of stool antigen CIDTs versus truly optimized culture conditions is unknown. In this issue of the Journal of Clinical Microbiology, Fitzgerald and colleagues (C. Fit...
