Background. Differentiating branch duct from mixed intraductal papillary mucinous neoplasm (BD-IPMN) is problematic, but clinically important as mixed IPMNs are managed surgically, while some BD-IPMN may be followed. Inflammatory mediator proteins (IMPs) have been implicated in acute and chronic inflammatory and malignant pancreatic diseases. Aim. To compare IMP profile of pancreatic cyst fluid...

| A convex upper bound of the mixed structured singular value is analyzed. The upper bound is based on a multiplier method. It is simple, it can exploit low-rank properties and it is shown to be less conservative than the well-known (D; G)-scaling. A direct relationship with (D; G)-scaling is given. The upper bound can be modiied to one that is continuous with an explicit Lipschitz constant. Ke...

Guantao Chen Department of Mathematics and Computing Science Georgia State University ATLANTA GA 30303 USA Given a graph theoretic parameter f, a graph H and a positive integer m, the mixed ramsey number f(m,H) is defmed as the least positive integer p such that for any graph G of order p either f(G) ~ m or G contains H as a subgraph. In this paper we determine the mixed ramsey number X2(m,K( I...

A new semiempirical approach is presented for predicting air-to-water oxygen transfer rates in mixed tanks and gravity sewers, using methods adopted from mixing theory. First, a flocculation unit was used to impart selected mean velocity gradients (G) into a completely mixed tank, from which oxygen was first removed, and dissolved oxygen concentrations were measured with time. Regression analys...

In the Mixed Chinese Postman Problem (MCPP), given a weighted mixed graph G (G may have both edges and arcs), our aim is to find a minimum weight closed walk traversing each edge and arc at least once. The MCPP parameterized by the number of edges in G or the number of arcs in G is fixed-parameter tractable as proved by van Bevern et al. (in press) and Gutin, Jones and Sheng (ESA 2014), respect...

objectives in the present study, we evaluated the antibacterial activity of capsella bursa-pastoris alone and also combined with glycyrrhiza glabra against streptococcus mutans, s. sanguis, actinomyces viscosus, enterococcus faecalis as oral pathogens. conclusions c. bursa-pastoris and its mixture with g. glabra are suggested as appropriate candidates to control dental caries and endodontic inf...

The G-star and the G-discrepancy are generalizations of the well known star and the extreme discrepancy; thereby G denotes a given continuous distribution function on the d-dimensional unit cube [0, 1]. We list and prove some results that describe the behavior of the G-star and the Gdiscrepancy in terms of the dimension d and the number of sample points N . Our main focus is on so-called mixed ...

A regular covering projection ℘: X̃ → X of connected graphs is G-admissible if G lifts along ℘. Denote by G̃ the lifted group, and let CT(℘) be the group of covering transformations. The projection is called G-split whenever the extension CT(℘) → G̃ → G splits. In this paper, split 2-covers are considered, with a particular emphasis given to cubic symmetric graphs. Supposing that G is transitive o...

Cell immobilization comprises the retention of metabolically active cells inside a polymeric matrix. In this study, the production of jabuticaba (Myrciaria jaboticaba) vinegar using immobilized Acetobacter aceti and Gluconobacter oxydans cells is proposed as a new method to prevent losses of jabuticaba fruit surplus. The pulp of jabuticaba was processed and Saccharomyces cerevisiae CCMA 0200 wa...

‎The purpose of this paper is to establish some coupled coincidence point theorems for mappings having a mixed $g$-monotone property in partially ordered metric spaces‎. ‎Also‎, ‎we present a result on the existence and uniqueness of coupled common fixed points‎. ‎The results presented in the paper generalize and extend several well-known results in the literature‎.
