Let t, v, k, λ be positive integers satisfying v > k > t. A t-(v, k, λ) design is an ordered pair (V,B), where V is a finite set of v points, B is a collection of k-subsets of V , say blocks, such that every t-subset of V occurs in exactly λ blocks in B. In what follows we simply write t-designs. A 3-(v, 4, 1) design is called a Steiner quadruple system and denoted by SQS(v). It is known that a...
OBJECTIVES Incidence and risk factors of post-transplant monoclonal gammopathy were studied in renal transplant patients who received their grafts between 1982 and 1992 (n = 390 grafts). Immunoelectrophoresis was performed at annual intervals after transplantation. RESULTS Forty-six cases of clonal gammopathy were detected: 35 monoclonal, 11 bi- or triclonal, with a predominance of IgG and ka...
BACKGROUND/AIMS First-line therapies against Helicobacter pylori, including proton pump inhibitors (PPIs) plus two antibiotics, may fail in up to 20% of patients. 'Rescue' therapy is usually needed for patients who failed the first-line treatment. This study evaluated the eradication rate of bismuth-containing quadruple rescue therapy over a 1- or 2-week period. METHODS We prospectively inves...
Radiodonts have long been known from Cambrian deposits preserving non-biomineralizing organisms. In Utah, the presence of these panarthropods in Spence and Wheeler (House Range Drum Mountains) biotas is now well-documented. Conversely, radiodont occurrences Marjum Formation remained scarce. Despite large amount work undertaken on its diverse fauna, only one ( Peytoia ) has reported Biota. this ...
BACKGROUND Furazolidone has recently shown promising efficacy in H. pylori eradication and has replaced metronidazole in different eradication regimens especially in countries, like Iran, with high prevalence of metronidazole resistance and where clarithromycin is expensive and hardly available. This study tries to determine the efficacy of a quadruple therapy based on furazolidone as a second ...
While activity recognition has been shown to be valuable for pervasive computing applications, less work has focused on techniques for forecasting the future occurrence of activities. We present an activity forecasting method to predict the time that will elapse until a target activity occurs. This method generates an activity forecast using a regression tree classifier and offers an advantage ...
We prove that every algebraic number contains infinitely many occurrences of 7/3-powers in its binary expansion. Using the same approach, we also show that every algebraic number contains either infinitely many occurrences of squares or infinitely many occurrences of one of the blocks 010 or 02120 in its ternary expansion.
