BACKGROUND The Congenital Cardiac Catheterization Project on Outcomes (C3PO) was established to develop outcome assessment methods for pediatric catheterization. METHODS AND RESULTS Six sites have been recording demographic, procedural and immediate outcome data on all cases, using a web-based system since February 2007. A sample of data was independently audited for validity and data complet...
let $r$ be a commutative ring with identity. an ideal $i$ of a ring $r$is called an annihilating ideal if there exists $rin rsetminus {0}$ such that $ir=(0)$ and an ideal $i$ of$r$ is called an essential ideal if $i$ has non-zero intersectionwith every other non-zero ideal of $r$. thesum-annihilating essential ideal graph of $r$, denoted by $mathcal{ae}_r$, isa graph whose vertex set is the set...
In recent years, the information overload caused by the new media has made the shortcomings of traditional Information Retrieval increasingly evident. Practical needs of industry, government organizations and individual users alike push the research community towards systems that can exactly pinpoint those parts of documents that contain the information requested, rather than return a set of re...
The invasion of a secondary forest within the city of Rio de Janeiro by Aedes aegypti and Ae. albopictus was evaluated from July 1997 to June 1998 through collections of immature stages in ovitraps set at 1 m, 10 m, 100 m, 500 m, and 1,000 m into the forest from houses on the periphery. Both mosquito species were much more abundant close to houses (1-10 m). Aedes aegypti was not collected beyon...
Our computational and experimental investigation of the reaction of anisole with Cl2 in nonpolar CCl4 solution challenges two fundamental tenets of the traditional SEAr (arenium ion) mechanism of aromatic electrophilic substitution. Instead of this direct substitution process, the alternative addition-elimination (AE) pathway is favored energetically. This AE mechanism rationalizes the preferre...
We present the preliminary results of applying a set of parameters of the AM-FM model for recognizing word utterances. By acquiring modulation based parameters from the amplitude envelope (AE) and the instantaneous frequency – both obtained by demodulating at four selected center frequencies – a compact feature set is created for each frame of a word utterance. Applying a dynamic time warping o...
چاودار به عنوان یک منبع ژنتیکی خارجی توسط اصلاح گرها به وفور در افزایش تنوع ژنتیکی گندم استفاده شده است، و کروموزوم 1r و بخصوص بازوی کوتاه آن 1rs به فراوانی به ژنوم گندم انتقال داده شده است. در مطالعات 1rs و انتخاب موثر از تکنیک های سیتوژنتیکی، بیوشیمیایی و نشانگرهای dna استفاده می شود. در این مطالعه وجود قطعات کروموزومی چاودار در بعضی از گونه های خانواده گندمیان با استفاده از یک جفت آغازگر اخت...
Geomagnetic storms and substorms develop under strong control of the solar wind. This is demonstrated by the fact that the geomagnetic activity indices Dst and AE can be predicted from the solar wind alone. A consequence of the strong control by a common source is that substorm and storm indices tend to be highly correlated. However, a part of this correlation is likely to be an eect of intern...
