In parsing theory, LL parsing and LR parsing are regarded to be two distinct methods. In this paper the relation between these methods is cla-riied. As shown in literature on parsing theory, for every context-free grammar, a so-called non-deterministic LR(0) automaton can be constructed. Here, we show, that traversing this automaton in a special way is equivalent to LL(1) parsing. This automato...
Label Ranking (LR) problems, such as predicting rankings of financial analysts, are becoming increasingly important in data mining. While there has been a significant amount of work on the development of learning algorithms for LR in recent years, preprocessing methods for LR are still very scarce. However, some methods, like Naive Bayes for LR and APRIORI-LR, cannot deal with real-valued data ...
We propose a low-rank stochastic gradient descent (LR-SGD) method for solving a class of semidefinite programming (SDP) problems. LR-SGD has clear computational advantages over the standard SGD peers as its iterative projection step (a SDP problem) can be solved in an efficient manner. Specifically, LR-SGD constructs a low-rank stochastic gradient and computes an optimal solution to the project...
A native, highly efficient microcystin-LR (MC-LR)-degrading bacterium named a7 was isolated from Lake Taihu and identified as Sphingopyxis sp. by 16S rDNA sequence analysis. The strain a7 could totally degrade MC-LR at a rate of 3.33 mg/(L•h), as detected by high-performance liquid chromatography (HPLC). The mlrA, mlrC, and mlrD genes were detected in the strain a7 by sequence analysis. Tetrape...
In this paper, we propose a method for constructing bigram LR tables by way of incorporating bigram constraints into an LR table. Using a bigram LR table, it is possible for a GLR parser to make use of both bigram and CFG constraints in natural language processing. Applying bigram LR tables to our GLR method has the following advantages: (1) Language models utilizing bigram LR tables have lower...

In this issue of the journal, Azzam and colleagues review the validation study of a clinical prediction rule for termination of resuscitation in patients suffering an out-of-hospital cardiac arrest. The clinical prediction rule is similar to a diagnostic test in that it predicts whether or not the patient will suffer the disorder of interest, in this case death, before hospital discharge. Given...
This study presents performance of upflow anaerobic sludge blanket (UASB) reactor in treating liquefied fleshings (LFs) with tannery wastewater (TWW) using liquefaction reactor (LR). With increase in recirculation rate, methane production increased in LR than in UASB reactor due to methanogenic bacteria in LR. UASB reactor with continuous feeding of LFs and TWW resulted with cumulative methane ...
Microcystin-LR (MCYST-LR), a hepatotoxin produced by cyanobacteria, inhibited purified protein phosphatases (PrPs) from rabbit skeletal muscle and the enzymes from Aplysia with an IC50 of approximately 10(-10) M. MCYST-LR also prolonged both serotonin- (5-HT) and cyclic adenosine monophosphate-induced inward currents in sensory neurons of Aplysia. These results, which are consistent with inhibi...
هدف: در این مطالعه عملکرد پیشبینی سه مدل آماری جهت تعیین ریسک فاکتورهای دیابت مقایسه گردید. مواد و روشها: شاخص توده بدن (BMI)، قندخون ناشتا (FBS)، فشارخون (HT)، چربیهای خون (TC، TG، HDL و LDL، HbA1C)، وزن و سابقه سیگار کشیدن از پرونده درمانی افراد تحت بررسی گردآوری شد. مدلهای شبکه عصبی مصنوعی پرسپترون چندلایه (MLP) و تحلیل ممیزی (DA) رگرسیون لجستیک (LR) به منظور شناسایی ریسک فاکتورها بر داد...
