It is known that the solutions of characteristic singular integral equations (SIEs) are expressed in terms of singular integrals of Cauchy type with weight functions w (x) = (1 + x)ν (1-x)μ, where ν = ± frac(1, 2), μ = ± frac(1, 2). New quadrature formulas (QFs) are presented to approximate the singular integrals (SIs) of Cauchy type for all solutions of characteristic SIE on the interval [-1, ...

Cercospora leaf spot (CLS), caused by the fungus Cercospora beticola (Sacc.), is the most destructive foliar pathogen of sugarbeet worldwide. Control measures include the use of resistant varieties and crop rotation, but timely fungicide applications are essential for CLS management. Resistance to sterol demethylation inhibitor (DMI) fungicides (FRAC group 3) has been increasing in C. beticola ...

We give a maximal independent set (MIS) algorithm that runs in $O(\log \log \Delta)$ rounds in the congested clique model, where $\Delta$ is the maximum degree of the input graph. This improves upon the $O(\frac{\log(\Delta) \cdot \log \log \Delta}{\sqrt{\log n}} + \log \log \Delta )$ rounds algorithm of [Ghaffari, PODC '17], where $n$ is the number of vertices of the input graph. In the first ...

In previous work we have developed the scheme of indeenite L-constraint databases where L, the parameter, is a rst-order constraint language. This scheme extends the constraint database proposal of Kanellakis, Kuper and Revesz to include in-deenite (or uncertain) information in the style of Imielinski and Lipski. In this paper we study the complexity of query evaluation in an important instance...

Logic and databases have gone a long way together since the advent of relational databases Already the rst basic query languages for relational databases beside relational algebra tuple calculus and domain calculus are actually a subset of rst order predicate logic Furthermore logic proved to be very adequate for establishing a sound theory for rela tional databases When attempts were made to i...

A quantile summary is a data structure that approximates to ε-relative error the order statistics of a much larger underlying dataset. In this paper we develop a randomized online quantile summary for the cash register data input model and comparison data domain model that uses O( 1 ε log 1 ε ) words of memory. This improves upon the previous best upper bound of O( 1 ε log 1 ε ) by Agarwal et. ...

Gomez, Avellana and Nicolas (2) studied early leprosy among Culion children and mentioned a few instances of disappearance, without treatment, of lesions that were either negative or positive bacteriologically. There is no subsequent record of those cases, and the period of their observations covered only about nine months. Lara and de Vera (3), in 1935, called attention to the occurrence in 7 ...

‎we consider two commutativity ratios $pr(g)$ and $f(g)$ in a finite group $g$‎ ‎and examine the properties of $g$ when these ratios are `large'‎. ‎we show that‎ ‎if $pr(g) > frac{7}{24}$‎, ‎then $g$ is metabelian and we give threshold‎ ‎results in the cases where $g$ is insoluble and $g'$ is nilpotent‎. ‎we also‎ ‎show that if $f(g) > frac{1}{2}$‎, ‎then $f(g) = frac{n+1}{2n}$‎, ‎for some‎ ‎na...

Several recent studies have introduced lightweight ver sions of Java reduced languages in which complex fea tures like threads and re ection are dropped to enable rigorous arguments about key properties such as type safety We carry this process a step further omitting almost all features of the full language including inter faces and even assignment to obtain a small calculus Featherweight Java...
