In this paper we present a method (linear in the size of the formal context) to solve the seriation problem for formal contexts. We show that any maximal solution can be represented by a PQ-Tree. Moreover, the set of PQ-Trees can be seen as a distributive lattice. This lattice yields a consensus method which deals with the multiple solutions.

Hematotoxicity in individuals genetically deficient in glucose-6-phosphate 22 dehydrogenase (G6PD) activity is the major limitation of primaquine (PQ), the only antimalarial 23 drug in clinical use for treatment of relapsing P. vivax malaria. PQ is currently clinically used in 24 its racemic form. A scalable procedure was developed to resolve racemic PQ thus providing pure 25 enantiomers for th...

In a previous experiment, we showed that among young and healthy subjects, thin plantar inserts improve postural control and modify vergence amplitudes. In this experiment, however, significant inter-individual variability was observed. We hypothesize that its origin could be attributed to a different reliance upon feet cutaneous afferents. In order to test this hypothesis, we re-analyzed the d...

BACKGROUND Primaquine (PQ) is the only currently licensed antimalarial that prevents Plasmodium vivax (Pv) relapses. It also clears mature P. falciparum (Pf) gametocytes, thereby reducing post-treatment transmission. Randomized PQ treatment in a treatment-to-reinfection cohort in Papua New Guinean children permitted the study of Pv and Pf gametocyte carriage after radical cure and to investigat...

since it is essential to deliver smoothed sinusoidal voltage to the customers, diagnosing power quality (pq) events has played important role in power delivery and conversion. this diagnostic scheme should be accurate to classify pq events from other events in power system. also it should be fast enough to rapidly mitigate pq events. in this paper, an algorithm based on core vector machine (cvm...

BACKGROUND Conventional ultrasound parameters such as the resistance index (RI) are only of limited use in the diagnosis of early allograft dysfunction. We, therefore, performed a prospective study to compare the value of ultrasound contrast media (USCM) with conventional US in the diagnosis of early allograft dysfunction. METHODS A total of 48 consecutive kidney recipients underwent US exami...

Paraquat (PQ) poisoning is a public health concern because there is no specific antidote. The effect of haemoperfusion (HP) in clearance of plasma PQ is conflict. The aim of this study is to determine the efficacy and safety of HP therapy in paraquat-poised patients. Bibliographic literature searches were conducted in PubMed, Web of Science and CNKI databases. Pooled data were analyzed by calcu...

BACKGROUND Paraquat (PQ) is an effective herbicide and is widely used in agricultural production, but PQ poisoning is frequently seen in humans with the lung as the target organ. Clinically pulmonary pathological changes are often used to predict the severity and prognosis of the patients. In this study, we observed the expression of heat shock protein 70 (HSP70) in rat lung after PQ poisoning ...

Let Z=(pq) be the integer residue ring modulo pq with odd prime numbers p and q. This paper studies the distinctness problem of modulo 2 reductions of two primitive sequences over Z=(pq), which has been studied by H.J. Chen and W.F. Qi in 2009. First, it is shown that almost every element in Z=(pq) occurs in a primitive sequence of order n > 2 over Z=(pq). Then based on this element distributio...

The mortality rate of acute paraquat (PQ) poisoning depends on the PQ concentration in the blood. It has been shown that the kidneys eliminate PQ effectively. However, early renal function deterioration is frequently observed in acute PQ intoxication. This study is designed to compare the efficacy of PQ elimination with hemoperfusion (HP) and kidneys, taking into account the functional deterior...
