In this paper, we address a problem that is often overlooked in the gradual construction of a logic-based knowledge component: how can a new piece of information g be added into a component KC so that g is not subsumed by KC? More precisely, the focus is on iterating this subsumption-freeness enforcement process when the component is increased step by step. Interestingly, it is shown that the a...

Supporting Results Structural Elucidation of [M+H] + m/z = 101.0232 Analysis of the n-butylamine-treated RNA from both E. coli and S. venezuelae indeed revealed the presence of a species consistent with the double addition of n-butylamine to the C4H4O3 unknown and the loss of two molecules of water (observed [M+H] + m/z = 211.1826; expected m/z for C12H23N2O= 211.1805. Treatment with d9-butylam...

The rings considered in this article are commutative with identity $1neq 0$. By a proper ideal of a ring $R$,  we mean an ideal $I$ of $R$ such that $Ineq R$.  We say that a proper ideal $I$ of a ring $R$ is a  maximal non-prime ideal if $I$ is not a prime ideal of $R$ but any proper ideal $A$ of $R$ with $ Isubseteq A$ and $Ineq A$ is a prime ideal. That is, among all the proper ideals of $R$,...

background :   vaculating cytotoxic a ( vaca ) gene is one of the multiple helicobacter pylori genotypes that produce a cytotoxin protein (vaca).this gene is a major cause of chronic peptic ulcers and gastric cancer. the aim of this study was to determine the correlation between vaca gene with peptic ulcer disease (pud) and non-ulcer dyspepsia (nud). methods :    this was a case control study o...

The flow behavior around a cam shaped tube in cross flow has been investigated experimentally using flow visualization and pressure distribution measurement. The range of attack angle and Reynolds number based on an equivalent circular diameter are within 0 ≤ α ≤ 360˚ and 2 x 104 < Reeq < 3.4 x 104, respectively. The pressure drag features are clarified in relation to the flow behavior around t...

There are situations that Decision Making Units (DMU’s) have uncertain information and their inputs and outputs cannot alter redially. To this end, this paper combines the rough set theorem (RST) and Data Envelopment Analysis (DEA) and proposes a non-redial Rough-DEA (RDEA) model so called additive rough-DEA model and illustrates the proposed model by a numerical example.
