Performance Comparison of OLSR and AODV Routing Protocols Using OPNET

A Mobile Ad hoc network(MANET) is a network consisting of a set of wireless mobile nodes, which communicate with each other without centralized control or established infrastructure. In this paper, to obtain a better understanding of AODV(Ad hoc On-Demand Distance Vector Routing Protocol)and OLSR(Optimized Link State Routing Protocol) routing protocols, different performances are simulated and analyzed using OPNET modeler 14.5 with the various performance metrics, such as packet delivery ratio, end-to-end delay and routing overhead. As a conclusion, in static analysis, the routing overhead of OLSR is affected by the number of nodes, but not data traffic. In AODV case, it is affected by both data traffic and number of nodes. In mobility analysis, routing overhead is not greatly affected by mobility speed in AODV and OLSR, and the PDR(Packet Delivery Ration) of OLSR is decreased as the node speed increased, while AODV is not changed. AS to delay, AODV is always higher than OLSR in both static and nobility cases.
Genotype-environment interaction between Chile and North America and between Chilean herd environmental categories for milk yield traits in Black and White cattle

In order to evaluate the expression of sire genetic evaluations obtained in North America for Chilean Black and White Cattle, genetic correlations were estimated for milk (MY), fat (FY) and protein (PY) yields, and for fat (F%) and protein (P%) contents between Chile, Canada and the US, from predicted transmitting abilities of common sires in two countries. Moreover, genetic correlations for the same traits were estimated between herd environmental categories formed according to MY levels, using bivariate analyses. Genetic correlation estimates for MY, FY, and PY between Chile-Canada (0.80, 0.61, and 0.70), and between Chile-US (0.79, 0.68, and 0.77), were lower than values obtained by simulation, assuming sire selection of the best 50%, and were also lower than the genetic correlations between Canada-USA, which were close to 1, suggesting a moderate genotype
ABUNDANCES, STELLAR PARAMETERS, AND SPECTRA FROM THE SDSS-III/APOGEE SURVEY

The SDSS-III/Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey operated from 2011–2014 using the APOGEE spectrograph, which collects high-resolution (R ∼ 22,500), near-IR (1.51–1.70 μm) spectra with a multiplexing (300 fiber-fed objects) capability. We describe the survey data products that are publicly available, which include catalogs with radial velocity, stellar parameters, and 15 elemental abundances for over 150,000 stars, as well as the more than 500,000 spectra from which these quantities are derived. Calibration relations for the stellar parameters ( T eff ? > , log g ? > , [M/H], [α/M]) and abundances (C, N, O, Na, Mg, Al, Si, S, K, Ca, Ti, V, Mn, Fe, Ni) are presented and discussed. The internal scatter of the abundances within clusters indicates that abundance precision is generally between 0.05 and 0.09 dex across a broad temperature range; it is smaller for some elemental abundances within more limited ranges and at high signal-to-noise ratio. We assess the accuracy of the abundances using comparison of mean cluster metallicities with literature values, APOGEE observations of the solar spectrum and of Arcturus, comparison of individual star abundances with other measurements, and consideration of the locus of derived parameters and abundances of the entire sample, and find that it is challenging to determine the absolute abundance scale; external accuracy may be good to 0.1–0.2 dex. Uncertainties may be larger at cooler temperatures ( T eff ? > < 4000 K ? > ). Access to the public data release and data products is described, and some guidance for using the data products is provided.

Disk-bulge decompositions of spiral galaxies in UBVRI

A sample of 26 bright spiral galaxies (B tot < 12.7) with low to medium inclination and without a bar was observed with UBVRI filters. The CAFOS focal reducer camera at the Calar Alto 2.2 m telescope was used. The surface-brightness distributions were fitted using a 2-dimensional algorithm with corresponding functions for the disk- and bulge-structure. For the disks an exponential function was used, for the bulges a Sersic R β law, was applied with the concentration parameter β = 1/n as another fit variable. Correlations of the resulting structural parameters of disks and bulges in UBVRI are investigated, giving clues to the formation history of the bulges. We confirm that the large and bright bulges of early-type spirals are similar to elliptical galaxies. They were probably formed prior to the disks in a monolithic collapse or via early mergers. Late-type spirals have tiny and faint bulges with disk-like profiles. These bulges were probably formed after the disk in secular evolution processes, e.g. from a disk instability. The comparison of the color indices of corresponding spirals and bulges with population synthesis computations support above formation scenarios.
Complex Carotid Stenting Using a Coronary Technique

Purpose: To report the utility of a coronary technique to facilitate carotid stenting in patients with difficult arch anatomies. Technique: When confronted with challenging arch anatomy that prevents engaging the common carotid artery (CCA) with the guiding sheath using standard techniques, an 8-F left Amplatz guiding catheter (AL1) is placed at the origin of the innominate artery. A 0.014-inch coronary guidewire is advanced into the external carotid artery (ECA), and a small monorail coronary balloon is inflated in a small branch of the ECA. The balloon/guidewire combination facilitates maneuvering a 0.035-inch Amplatz super-stiff guidewire through the ECA and then advancing the guiding catheter into the CCA. Conclusion: This anchoring technique can be a helpful method for cannulating the CCA in patients with a complex arch when the ECA is patent.
Petrophysical Properties and Microstructural Analysis of Faulted Heterolithic Packages: A Case Study from Miocene Turbidite Successions, Italy

Geofluid reservoirs located in heterolithic successions (e.g., turbidites) can be affected by vertical and lateral compartmentalization due to interbedded fine-grained facies (i.e., shale, siltstones) and the presence of faults, respectively. A fault can behave as a conduit or barrier to fluid flow depending on its architecture and the individual hydraulic behavior of its components (i.e., fault core, damage zone). The fault core, normally composed by fault rock or smeared clay material, commonly acts as a flow inhibitor across the fault. Fault-related fractures (macro- and microscopic) in the damage zone generally increase the permeability parallel to the fault, except when they are cemented or filled with gouge material. Although macrofractures (which define the fracture porosity) dominate fluid flow, the matrix porosity (including microfractures) begins to have a more important role in fluid flow as the aperture of macrofractures is occluded, particularly at greater depth. This study investigates the variation in matrix permeability in fault zones hosted in heterolithic successions due to fault architecture and stratigraphy of host rock (i.e., sand-rich turbidites). Two key areas of well-exposed, faulted Miocene turbidites located in central and southern Italy were selected. For this study, six separate fault zones of varying offset were chosen. Each impacts heterolithic successions that formed under similar tectonic conditions and burial depths. Across the selected fault zones, an extensive petrophysical analysis was done in the field and laboratory, through air permeameter measurements, thin section, and synchrotron analysis in both host rock, damage zone, and fault core. Results suggest that the amount and distribution of clay layers in a heterolithic sequence affects fluid flow across the fault, regardless of fault offset.
Automatic monitoring system for of the Sevastopol Black Sea region marine environment

Operational monitoring system is developed to automatize the process of diagnosis and forecast of hydrological fields of marine environment in the Sevastopol Black Sea region based on the local hydrodynamical model POM. The initial and boundary conditions for the local model are set from the basin model of the Black Sea dynamics. The data obtained by SKIRON Regional Forecast Center of Athens University is applied as the atmospheric effect. For the parameterization of vertical mixing in local circulation model POM turbulence model based on turbulence hypotheses of Rott – Kolmogorov and generalized by Mellor and Yamada in the case of a stratified flow is included. The model takes into consideration the penetration of the short-wave solar radiation into the water column. System automation is implemented using the CalcMan software package which is an own development of Marine Hydrophysical Institute. The output fields are accessible in the NetCDF format with horizontal spatial resolution constituting 1 km, vertical resolution – 18 irregular levels from 2.5 to 1000 m and time resolution – 3 hr. The system provides a possibility of daily updating the forecast data. Based on the THREDDS server, the specialized visualization subsystem is installed and configured to visualize and disseminate simulations results. Its user-friendly interface allows a server-side analysis of all the forecasted fields, permits to construct horizontal and vertical sections, vertical profiles and time series, to create animated pictures without downloading the data to a client’s side. OPENDAP and NetcdfSubset interfaces are used for disseminating data in a digital form.
The influence of meteorological conditions and complex topography on ozone concentrations in a valley area near coastal metropolitan cities

The influences of meteorological conditions and complex topography on ozone (O3) concentrations were evaluated at two different sites [Jung Ang (JA): a semi-closed topography and Seo Chang (SC): a closed topography] within a valley city neighboring coastal metropolitan cities (Busan and Ulsan) during days exhibiting high O3 episodes (8 and 10 August 2006), using the MM5-CMAQ modeling system. The contributions of physical and chemical processes to the O3 concentrations were also assessed within the mixed layers of the two sites (JA and SC) during the study period. High O3 concentrations at site JA on 8 August were the result of combined effects of the horizontal transport (in a north-south direction) of O3 and its precursors and their subsequent reaction with southerly (from Busan) and easterly sea breezes (from Ulsan) and their accumulation due to the convergence of these sea breezes. Such O3 enhancements on 10 August were caused mainly by the vertical transport of O3 and its precursors and partly by their accumulation (from local emission sources) due to weak winds. Unlike site JA, the O3 enhancement at site SC on 8 August was mainly ascribable to horizontal transport (in an east-west direction) from the source regions of Ulsan. On 10 August, vertical transport of downslope flows from the top of mountains largely contributed to O3 concentrations. In addition, the heights of maximum O3 inflow due to horizontal or vertical transport between the two sites during the episodes were different depending on the differences in the heights of mountains and/or the movement directions and intensities of sea breezes.
SEXUAL SIZE DIMORPHISM AND ASSORTATIVE MATING IN THE BROWN NODDY

We report the results of a biometric study of adult Brown Noddies (Anous stolidus) nesting within the Culebra National Wildlife Refuge, Puerto Rico in 1985-1988. The body mass of adults varied significantly between years, but linear measurements did not. Males were significantly larger than females in all body measurements. This difference also was reflected within pairs. A discriminant function using head-bill and wing length successfully predicted the sex of 90% of birds. Measurements of male and female partners indicated that they were not paired at random with respect to body mass and showed positive assortative mating for this character. The causes and consequences of this relationship are discussed.
Last male sperm precedence in a polygamous squid

Differential sperm usage from consecutive matings, or sperm precedence, is vital in determining male reproductive success and the outcome of sperm competition for many organisms. Sperm precedence also has significant consequences for mating system dynamics, including both male and female adaptations for increasing reproductive success and avoiding the costs of mating. Despite sexual selection being a strong driver of reproductive behaviour and morphology in cephalopods, surprisingly few studies have investigated sperm dynamics in this group. To redress this gap, we experimentally quantified sperm precedence patterns in the dumpling squid, Euprymna tasmanica, controlling for recent male mating history (first vs. second mating), mating position, and mating frequency. We found that the last male to mate gains an advantage in this system, with the second mating male siring up to 75% of offspring at the beginning of the laying period. The proportion of offspring attributable to the second mating male decreases to 54% by the end of the laying period, potentially as a result of changes in the velocity or number of sperm released from spermatangia over time. There is also significant variation among females in patterns of sperm precedence. This variation was not associated with whether it was the male's first or second mating, male mass, the duration of copulation or the number of pumps (sperm removal behaviour) by the second male. If widespread in cephalopods, last male sperm precedence could help to explain the evolution of mate guarding (or long copulation duration) and sperm removal behaviour in this group.
New species of graphidoid and thelotremoid Graphidaceae from Australia

Four new graphidoid and thelotremoid Graphidaceae are described from Australia, all supported by previously published molecular data. Fissurina bullata Mangold, Lucking & Lumbsch differs from other Fissurina species in having a strongly bullate thallus with large clusters of calcium oxalate crystals, in combination with a psoromic acid chemistry. Ocellularia australiana Mangold, Lucking & Lumbsch is similar to O. wirthii in having a white-grey thallus and in containing psoromic acid but differs in the loose cortex and the more irregular ascomata with partly fissured margins and often divided, thickly white-tipped columella, as well as slightly larger ascospores. Thelotrema fuscosubtile Mangold, Lucking & Lumbsch was previously confused with T. subtile but can be distinguished by the prominent ascomata and in the ascospores becoming pale brown. Finally, T. inspersoporinaceum Mangold, Lucking & Lumbsch differs from T. porinaceum in having an inspersed hymenium.
Responses of microbial food web to increased allochthonous DOM in an oligotrophic subarctic lake

Climate-induced changes in catchment area vegetation and runoff alter the quality and quantity of carbon that enters lakes, with implications for food webs in recipient water bodies. The effect of dissolved organic matter (DOM) on the ratio between heterotrophic and autotrophic biomass and productivity was studied in a subarctic, clear water lake in northern Finland. In a mesocosm experiment, natural DOM from a subarctic bog and a boreal lake was added to the lake water, doubling the initial dissolved organic carbon (DOC) concentration. Optical indices sug- gested that the subarctic DOM addition was more bioavailable, which was in line with the greater increase in bacterial biomass and production observed in this treatment. Both DOM additions increased the abundance of heterotrophic nanoflagellates (HNF) and decreased primary produc- tivity. They also led to lower ratios of primary to bacterial production, autotrophic to mixotrophic algae and pigmented nanoflagellates (PNF) to HNF relative to the control samples, indicating a shift from a primary production-based food web towards one based on bacterial production. A comparable increase in DOM in the natural environment would lead to a considerable decrease in the euphotic layer and loss of areas available for primary production, resulting in a shift towards a heterotrophic production based food web.
Systematic Literature Review of Critical Success Factors of Information Technology Startups

In the industry of Information Technology (IT) Startup, high birth rates go hand in hand with a high risk of failure; only one in three survive the first three years. There is a set of factors that influence the success of the Startup. So in this paper we present a Systematic Literature Review of critical success factors of IT Startups. Our keyword search found 1,013 papers and a total of 74 primary studies were selected and analyzed as a result of the systematic review. We identified 21 critical success factors grouped into three categories (organizational, individual and external) and 4 stages of development through which a Startup passes (seed, early, growth and expansion). In addition, we found that the experience previous start-up of the founding team and government support factors affect the seed stage; the venture capital factor affects the early stage; the clustering, technological/business capabilities of the founding team and venture capital factors affect the growth stage; and the clustering factor affects the expansion stage. There are few studies on the stages of development that a Startup undergoes, much less on the factors that affect the stages of development.
Research of Voltage-Balancing Methods of Series-Connected IGBTs

Voltage-balancing method is the key to the application of series-connected Insulated-Gate Bipolar Transistor(IGBT). In this paper the voltage-balancing process is divided into 4 stages: dynamic turning-on process, dynamic turning-off process, the tail current state and steady state, whose voltage-balancing methods are then proposed respectively: gate compensation capacitor network for dynamic process; resistance capacitance(RC) voltage-balancing circuit designed for tail current state with the capacitance given by a formula; and parallel-connected voltage-balancing resistance for the steady state. Based on the work above, power module of two series-connected IGBTs is designed and tested under high voltage and high current condition. The result shows that under the series total voltage 2kV (1.85kV maximum peak voltage for each IGBT) and 2kA current, the power module balanced the voltage of the whole period of an turning on and off process, and both of the voltage-unbalance-rate of dynamic and steady state are less than 5%.
A Network Analysis Method for Tailoring Academic Programs

Producing or updating an academic program implies a significant effort: involving people, academic units, knowledge elements, regulations, institutions, industry, etc. Such effort entails a complexity related to the volume of elements involved, the diversity of the origins of contributions, the diversity of formats, the representation of information, and the required granularity. Moreover, such effort is a common task performed by humans who collaborate for long periods of time participating in frequent meetings in order to achieve agreement. New educational approaches are heading to adaptive, flexible, ubiquitous, asynchronous, collaborative, hyper-mediated, and personalized strategies based on modern Information and Communication Technologies (ICT). We propose an approach for tailoring academic programs to provide a practical and automated method to discover and organize milestones of knowledge through the use of Complex Networks Analysis (CNA) techniques. Based on indicators from CNA, the act of tailoring an academic program acquires meaning, structure and even body elements.
Effect of Bacillus thuringiensis on microbial functional groups in sorghum rhizosphere

The objective of this work was to assess the effect of two strains of Bacillus thuringiensis var. kurstaki on sorghum rhizosphere microorganisms. The strains were HD1, that produces the bioinsecticidal protein, and 407, that is a mutant non-producer. The strains do not influence microbial population, but reduce plant growth and improve mycorrhizal colonization and free living fixing N2 community.
REFINEMENT OF PHYLOGENETIC SIGNAL IN MULTIPLE SEQUENCE ALIGNMENT: RESULTS OF SIMULATION STUDY

*SUMMARY Motivation: Disparate substitution rates within the different regions of homologous sequences and mutational saturation are well known to cause misalignment of sequences and to hamper accurate tree reconstruction. Therefore, there is a need in tools detecting and filtering out informational noise from the multiple alignment of sequence data; the tools will help to increase accuracy and resolution of phylogenetic analyses. Results: We propose such a tool and tested its ability to improve the quality phylogenetic trees both on the biological COG data, and on the artificial data, where the ideal tree was known a priory. The key operation of the filtering is a removal of noisy columns. It was shown that the tool permits to reconstruct a tree closer to the “true” tree than is the tree reconstructed with data without removal. Procedure can be applied as a tool to pre-process multiple alignments and enhance phylogenetic inference.
