The CFA Institute Code of Ethics and Standards of Professional Conduct are fundamental to the values of CFA Institute and essential to achieving its mission to lead the investment profession globally by promoting the highest standards of ethics, education, and professional excellence for the ultimate benefit of society. High ethical standards are critical to maintaining the public’s trust in fi...

Common factor analysis (CFA) and principal component analysis (PCA) are widely used multivariate techniques. Using simulations, we compared CFA with PCA loadings for distortions of a perfect cluster configuration. Results showed that nonzero PCA loadings were higher and more stable than nonzero CFA loadings. Compared to CFA loadings, PCA loadings correlated weakly with the true factor loadings ...

Monoclonal antibodies (MAbs) against the different coli surface antigens CS1, CS2, and CS3 of colonization factor antigen II (CFA/II) of enterotoxigenic Escherichia coli (ETEC) were generated by fusing F/O myeloma cells with spleen cells from BALB/c mice immunized with different preparations of purified CFA/II. Five hybrids that produced antibodies specific for CS1, CS2, or CS3 in high titer we...

OBJECTIVE The common femoral artery (CFA) is an unusual location for endovascular repair (ER). We report the early results after ER of the CFA in a single centre. DESIGN This is a cohort study. MATERIALS/METHODS From 2006 to 2008, ER of the CFA was proposed to 36 patients (mean age 67.9, range 51-92). CFA lesions were classified into four types: in type I, lesions were located at the iliac ...

Although primary particle emissions of ash from coal-fired power plants are well controlled, coal fly ash (CFA) can still remain a significant fraction of the overall particle exposure for some plant workers and highly impacted communities. The effect of CFA on pulmonary and systemic inflammation and injury was measured in male Sprague-Dawley rats exposed to filtered air or CFA for 4 h/day for ...

BACKGROUND Tissue injury elicits both hypersensitivity to evoked stimuli and ongoing, stimulus-independent pain. We previously demonstrated that pain relief elicits reward in nerve-injured rats. This approach was used to evaluate the temporal and mechanistic features of inflammation-induced ongoing pain. RESULTS Intraplantar Complete Freund's Adjuvant (CFA) produced thermal hyperalgesia and g...

Screen-printed electrode (SPE) modified with carbon black nanoparticles (CB) has been tested as a new platform for the stable deposition of caffeic acid (CFA) on the electrode surface. The electrochemical performance from varying the amount of CFA/CB composite has been tested with respect to NADH determination. The electrocatalytic activity of CFA/CB has also been compared with that of SPEs mod...

A spacecraft simulation environment was developed for testing distributed spacecraft flight software (FSW) designed for autonomous coordinated control of a spacecraft cluster. The Cluster Flight Application (CFA) FSW was developed by Emergent Space Technologies in support of the Defense Advanced Research Projects Agency (DARPA) System F6 Program. The CFA provides cluster flight guidance, naviga...

Previous studies in our laboratory have shown that the subcutaneous pretreatment of rats with heat-killed cells (HKC) of Cryptococcus neoformans emulsified in complete Freund adjuvant (CFA) promotes protective immunity against an intraperitoneal challenge with C. neoformans. In contrast, subcutaneous treatment with the capsular polysaccharide (PSC) emulsified in CFA exacerbates the cryptococcal...

Hybridoma cell lines secreting antibodies to chicken fetal antigens (CFAs) were generated by the fusion of mouse P3X63Ag8 myeloma cells with spleen cells from a mouse immunized with intact SC chicken strain one-day-hatched red blood cells. Immunodepletion studies show monoclonal anti-CFA to be detecting a subset of the Mr 50,000 CFA molecules recognized by polyclonal anti-CFA. Monoclonal anti-C...
