The FindStat project provides an online platform for mathematicians, particularly for combinatorialists, to gather information about combinatorial statistics and their relations. As of January 2014, the FindStat database contains 173 statistics on 17 combinatorial collections. The project was initiated by Chris Berg and Christian Stump in 2011 at the Laboratoire de combinatoire et d’informatiqu...

Although software updates are extensively used to enhance software while already being used, their impact on users’ post-adoption beliefs and attitudes has received little attention. Drawing on expectation-confirmation-theory and the IS continuance model, we investigate if and how feature updates affect users’ continuance intentions (CI) and what role initial feature endowment and update size p...

The MICs and MBCs of CI-934, ciprofloxacin, difloxacin (A-56619), A-56620, norfloxacin, enoxacin, amifloxacin, and coumermycin were determined for 43 clinical isolates of Enterococcus faecalis known to be resistant to penicillin-aminoglycoside synergy. Results were compared with those obtained for 37 synergy-susceptible E. faecalis and 22 Enterococcus faecium strains. Although no substantial di...

Background: Fetal male gender may affect the progression of labor and could be a risk factor for labor arrest. This study was conducted to evaluate the effect of fetus gender on labor curve.    Methods: In this cohort study, 1550 singleton term pregnant women in labor phase (either spontaneous or by induction) were enrolled. Results of regular cervical examination, dilation, length o...

BACKGROUND We assessed optimal intravascular ultrasound (IVUS) criteria for predicting functional significance of intermediate coronary lesions. METHODS AND RESULTS Overall, 201 patients with 236 coronary lesions underwent IVUS and invasive physiological assessment before intervention. Fractional flow reserve (FFR) was measured at maximal hyperemia induced by intravenous adenosine infusion. F...

OBJECTIVE The aim of the study was to assess the accuracy of N-terminal probrain natriuretic peptide (NT-proBNP) to predict mortality or detect acute ischemia in patients with coronary artery disease (CAD). METHODS This study included 1,552 patients with stable (n = 1,059) or unstable (n = 493) CAD undergoing percutaneous coronary intervention. NT-proBNP was measured before percutaneous coron...

OBJECTIVE To evaluate the accuracy of an interferongamma release assay (QuantiFERON-TB Gold in Tube) for diagnosing Mycobacterium tuberculosis infection in a young pediatric population. METHODS 195 children previously vaccinated with BCG were evaluated, being 184 healthy individuals with no clinical or epidemiological evidence of mycobacterial infection, and 11 with Mycobacterium tuberculosis...

background: the diagnosis of pulmonary tuberculosis (ptb) is complicated and time-consuming currently. there was association of ptb with serum tumor markers. in this study we aimed to evaluate the predictive role of serum ca125, ca199 and cea as diagnostic tools for ptb. methods: this study was designed as a case-control study with 565 subjects who visited the yijishan hospital from jun to dec ...
