We propose a new parallelized high-dimensional single-query path planning technique that uses a coupled forest of random trees (i.e., instead of a single tree). We present both theoretical and experimental results that show using forests of random trees can lead to expected super linear speedup, with respect to the number of trees in the forest. In other words, with T trees running in parallel,...

Background & objective: Microbial contamination is one of the main concerns about the use of treated wastewater in irrigation. Therefore, the present study conducted to investigate the effect of treated wastewater on microbial contamination of urban landscape soils in Zahedan. Material & methods: In this study, a 1600 m2 plot of palm trees in Zahedan were irrigated with treated wastewater and o...

Appropriate and extensive taxon sampling is one of the most important determinants of accurate phylogenetic estimation. In addition, accuracy of inferences about evolutionary processes obtained from phylogenetic analyses is improved significantly by thorough taxon sampling efforts. Much of the previous work examining the impact of taxon sampling on phylogenetic accuracy has focused on the effec...

Pecan bacterial leaf scorch (PBLS) and the pathogen Xylella fastidiosa were identified in 20 pecan cultivars observed in Louisiana commercial orchards over a twoyear period. The disease occurred in the majority of orchards observed and was distributed throughout the pecan growing areas of the state. Leaf scorch was most prevalent in the Cape Fear cultivar. A few other cultivars sometimes exhibi...

        In this research, modeling tree height distributions of beech in natural forests of Masal that is located in Guilan province; was investigated. Inventory was carried out using systematic random sampling with network dimensions of 150×200 m and area sample plot of 0.1 ha. DBH and heights of 630 beech trees in 30 sample plots were measured. Beta, Gamma, Normal, Log-normal and Weibull prob...

gestational diabetes increases the risks for mother and fetus during pregnancy. as a principle of caring for diabetes, recommending patients to lose weight through more physical activities and a restrictive diet has a long history. the present study was carried out aiming at determining and comparing dietary style and physical activity in women with gestational diabetes and healthy pregnant wom...

In order to investigate the seasonal changes and the possible role of the free polyamines in the leaves and stems on the alternate bearing habit of the ‘Kinnow’ mandarin (Citrus reticulata Blanco) trees, a comparative study was conducted to analyze the levels of free polyamines  (putrescine, spermidine and spermine) in the leaves and stems tissues of “on” and &ldquo...

  Background and purpose: Introduction of antiretroviral therapy has led to decline in AIDS-associated cancers. In recent years, the rate of non-AIDS associated cancers has increased. Current prevalence of AIDS-associated cancers in Iran is unknown, so we aimed to investigate the prevalence of different cancers among HIV-infected patients in Iran. Materials and methods: A cross-sectional surv...
