Abstract Whale optimization algorithm (WOA) is a new population-based metaheuristic algorithm. WOA uses shrinking encircling mechanism, spiral rise, and random learning strategies to update whale’s positions. WOA has merit in terms of simple calculation and high computational accuracy, but its convergence speed is slow and it is easy to fall into the local optimal solution. In order to overcome the shortcomings, this paper integrates adaptive neighborhood and hybrid mutation strategies into whale optimization algorithms, designs the average distance from itself to other whales as an adaptive neighborhood radius, and chooses to learn from the optimal solution in the neighborhood instead of… More >

Abstract Anomaly detection in smart homes provides support to enhance the health and safety of people who live alone. Compared to the previous studies done on this topic, less attention has been given to hybrid methods. This paper presents a two-steps hybrid probabilistic anomaly detection model in the smart home. First, it employs various algorithms with different characteristics to detect anomalies from sensory data. Then, it aggregates their results using a Bayesian network. In this Bayesian network, abnormal events are detected through calculating the probability of abnormality given anomaly detection results of base methods. Experimental evaluation of a real dataset indicates… More >

Abstract Spermatocytes from the two armadillo species, C. villosus and D. hybridus were studied in microspreads for synaptonemal complexes (SCs) and in thin sections for electron microscopy (EM). The complete SC karyotype generally agrees with previous reports on mitotic chromosomes, except for the sex chromosomes. The X chromosome is submetacentric in both species and the Y is the shortest one in C. villosus and the second shortest in D. hybridus, and an extremely acrocentric one. A SC is formed along the total length of the Y chromosome, and this SC persists along all the pachytene substages. A single recombination nodule (RN)… More >

Abstract The ribosomal DNA (45S rDNA) behaviors during the cell cycle were analyzed on interphase nuclei, prophases, metaphases, pachytene chromosomes and extended DNA fibers in rice (Oryza,sativa ssp.indica cv.Guangluai No.4) by using high-resolution fluorescent in situ hybridization (FISH). The results show that 45S rDNA is located at the ends of short arms of chromosomes 9 and 10. But the signals are much more intense on chromosome 9 than on chromosome 10 in metaphase. Pachytene chromosome has rDNA signal arrays on chromosome 9. Different phases are described and discussed. These results indicate that the activity of rDNA at individual loci may also… More >

Abstract In the floriculture region of Tenancingo in the State of Mexico, the application of stabilized organic matter, such as vermicompost and leachates, contributes to improve the quality of the soil and plant nutrition. However, it is important to know the chemical composition of a vermicompost and the mineralization process. This is because the amount and speed of nutrient release which will be available to the crop will depend on that knowledge. The objective of the study was to evaluate the effect of the application of a vermicompost and leachates on various quantitative variables of Solidago x hybrid, and the mineralization… More >

Abstract Cultivated surfaces of genetically modified (GM) crops increased year by year, becoming in 2012 more extensive in developed than in industrialized countries. Furthermore, it has been postulated that the plant is which leads to the selection of the microorganisms on its root exudates, creating specific conditions which in turn regulate the specific microbial structure of each plant. In this study, our main objective was to examine whether the introduction of transgenic maize herbicide-tolerant plants will impact the microbial structures that inhabit at the rhizosphere and rhizoplane with respect to conventional hybrid maize plants. Bacterial populations were determined (CFU/g) using four… More >

Abstract In many countries, tomato (Solanum lycopersicum L.) is the most important horticultural species, but good variety seeds are expensive. In hybrid breeding, the number of possible single crosses is too large with only a few lines. With 60 lines, for example, 1770 single-cross hybrids can be formed. This makes it expensive and even impossible to conduct an adequate experimental evaluation. These cases require the availability of methods for predicting hybrid performance. This study was designed to evaluate a method to predict fruit yield in tomato hybrids based on genomic fingerprints, the theory of mixed models, and the experimental evaluation of… More >

Abstract The Toluca´s México valley is considered a high valley because it is situated at 2560 m.a.s.l. In this region, maize is the most important crop; free pollination [Yellow, red, blue and flour maize (Cacahuacintle)] and hybrid materials are grown. Corn yield is negatively affected by an inadequate P fertilization. The aim of this study was to determine the agronomic effectiveness of phosphorus in terms of biomass and yield on three cultivars of maize as a function of six levels of phosphorus fertilization in the Toluca´s valley, Mexico. The materials Amarillo Almoloya, Cacahuacintle and Cóndor were sown under a completely randomized… More >

Abstract Micromorphological and anatomical differences in leaf epidermis and stem xylem of Rosa hybrida ‘Lovely Red ‘ (LR) and ‘Rouge Baiser’ (RB), commercially grown in Buenos Aires, Argentina, were examined in the lower half of the terminal leaflet of 5-foliate leaves and in the basal part of stem, respectively. Digital images obtained from SEM and a phase contrast microscope were used with this purpose. Epicuticular wax, which was present on both sides of the leaves, was more abundant in LR than in RB. Stomata were only present on the abaxial side; they were 111 and 129 per mm² in LR and… More >

Abstract The photosynthetic and morphological characteristics, and microstructure of roots and shoots, were studied between columnar apple and standard apple trees derived from the crosses of ‘Fuji’ × ‘Telamon’ and ‘Gala’ × ‘Telamon’. The results showed that chlorophyll A, chlorophyll B, the content of chlorophyll A+B, and leaf area index were higher in columnar apple trees than in standard apple trees. In a day cycle, the net photosynthetic (Pn) and transpiration rates (Tr) were higher in the columnar apple trees than in standard apple trees. The daily variations of Pn and Tr were of a double peak cure. Light saturation points… More >
