We show that the complete list of regular excluded minors for the class of signed-graphic matroids is M(G1), . . . ,M(G29), R15, R16. Here G1, . . . , G29 are the vertically 2-connected excluded minors for the class of projective-planar graphs.

OBJECTIVE To establish a reliable equation to predict hepatic venous pressure gradient (HVPG) using serological tests for surgical patients with hepatocellular carcinoma (HCC). BACKGROUND Accurate assessment of portal pressure for surgical patients with HCC is important for safe hepatic resection (HR). The HVPG is regarded as the most reliable method to detect portal hypertension. However, HV...

the impulse oscillation system (ios) measures respiratory impedance (zrs) in terms of resistance (rrs) and reactance (xrs) at multiples of 5 hz. these measurements can be used clinically to help diagnose and monitor respiratory disorders, independent of effort. there is, as yet, no information on reference values for ios in iranian adolescents. the predictive equation for resistance and impedan...

The field experiments related to the study were conducted at Punjab Agricultural University, Ludhiana and Krishi Vigyan Kendra, Bahowal. There 20 treatment combinations comprising of four levels sunlight intensity [control (full sunlight), 50% reduction in light during 15-45(R15-45), 46-75(R46-75) 76-105(R76-105) DAT] five foliar nitrogen application (only recommended nitrogen, no spray), spray...

OBJECTIVE To study the effects of an acute therapeutic oral intake of beta(2) agonist on performance and substrate response during supramaximal exercise in women. METHODS 12 healthy moderately trained female volunteers performed a Wingate test after ingestion of placebo (Pla) and salbutamol (Sal; 4 mg) according to a double-blind randomised crossover study. Blood samples were collected at res...

Laparoscopic hepatectomy is a standard surgical procedure. However, it is difficult to perform in patients with severe cirrhosis because of fibrosis and a high risk of hemorrhage. We report our recent experience in five cases of pure laparoscopic hepatectomy combined with a pure laparoscopic Pringle maneuver in patients with severe cirrhosis. From 2012 to 2014, we performed pure laparoscopic pa...

In this paper we endogenously group 311 U.S. cities by using dynamic clustering techniques. Then, we try to determine what the economic determinants of clustering are. In so doing, we use a spatial econometric model that disentangles the effect of intercity interactions operating through the input-output matrix from the effect of all others interactions. Preliminary incomplete version Do not ci...
