Phylogenetic characterization of bovine parainfluenza 3 from contaminated cell cultures and field is

Genomic fragments of the HN and L genes from Brazilian bovine parainfluenza 3 virus (bPIV-3) isolated as contaminants from cell cultures and clinical specimens were amplified by reverse transcription-polymerase chain reaction (RT-PCR), sequenced using specific degenerate primers and analyzed by phylogenetic comparison with reference strains of bPI3V. The Brazilian isolates revealed a high degree of genomic when compared to SF4/32 prototype strain, within the recently proposed genotype A of bPIV-3.
Fermentation kinetics (in vitro) of Leucaena leucocephala, Gliricidia sepium and Calliandra callothyrsus leaves (3) the pattern of gas production, organic matter degradation, pH, NH3 and VFA concentration; estimated CH4 and microbial biomass production

In high protein feeds, plant proteins may be shielded from degradation in the rumen by lignification of the cell wall or because of the present of plant secondary compounds e.g. tannin, which is present in most of the leguminous trees/shrubs. Thus it might have an effect on organic matter degradation and the pattern of other end product of rumen microbial fermentation (VFA, NH 3 , microbial cell, CH 4 and total gas). The in vitro method was used to determine the organic matter degradation and the pattern of rumen fermentation end product of high protein feeds, namely Leucaena leucocephala, Gliricida sepium and Calliandra calothyrsus . The results shows that Gliricidia has the highest amount of OM degraded (505 mg); microbial cell and NH 3 produced (2676 g and 1.91 mmol/100 mL) than followed by Leucaena (423 mg; 2656 g; 1.61 mmol/100 mL) and Calliandra (340 mg; 2644 g; 1.61 mmol/100mL), but Gliricidia produced the lowest amount of gas total and CH 4 (0.192 mL and 0.07 mole per mg OM deraded) then Leucaena (0.249 mL and 0.097 mole per mg OM deraded) and Callliandra (0.196 mL and 0.126 mole per mg OM deraded). In conclusion, Gliricidia is more efficient in term of using the dietary energy for the animals’ production compared to the Leucaena and Calliandra.

A Memristor-Based Cascaded Neural Networks for Specific Target Recognition

Multiply-accumulate calculations using a memristor crossbar array is an important method to realize neuromorphic computing. However, the memristor array fabrication technology is still immature, and it is difficult to fabricate large-scale arrays with high-yield, which restricts the development of memristor-based neuromorphic computing technology. Therefore, cascading small-scale arrays to achieve the neuromorphic computational ability that can be achieved by large-scale arrays, which is of great significance for promoting the application of memristor-based neuromorphic computing. To address this issue, we present a memristor-based cascaded framework with some basic computation units, several neural network processing units can be cascaded by this means to improve the processing capability of the dataset. Besides, we introduce a split method to reduce pressure of input terminal. Compared with VGGNet and GoogLeNet, the proposed cascaded framework can achieve 93.54% Fashion-MNIST accuracy under the 4.15M parameters. Extensive experiments with Ti/AlOx/TaOx/Pt we fabricated are conducted to show that the circuit simulation results can still provide a high recognition accuracy, and the recognition accuracy loss after circuit simulation can be controlled at around 0.26%.
Suprabasal α6β4 integrin expression in epidermis results in enhanced tumourigenesis and disruption of TGFβ signalling

Inappropriate α6β4 integrin expression correlates with a high risk of tumour progression in stratified squamous epithelia. Targeted expression of α6β4 in the suprabasal layers of transgenic mouse epidermis dramatically increased the frequency of papillomas, carcinomas and metastases induced by chemical carcinogenesis, independent of the β4 cytoplasmic domain. Suprabasal α6β4 also perturbed transforming growth factor β (TGFβ) signalling as demonstrated by decreased nuclear Smad2 in transgenic epidermis and tumours. In cultured keratinocytes, suprabasal α6β4 relieved TGFβ-mediated growth inhibition and blocked nuclear translocation of activated Smad2/3. Responsiveness to TGFβ could be restored by inhibiting cadherin-mediated cell-cell adhesion or phosphoinositide 3-kinase (PI3-K) activity, but not by inhibiting mitogen-activated protein kinase (MAPK) activity. These data suggest that suprabasal α6β4 promotes tumourigenesis by preventing TGFβ from suppressing clonal expansion of initiated cells in the epidermal basal layer.
Effect of population density on the development of Mesovelia furcata (Mesoveliidae), Microvelia reticulata and Velia caprai (Veliidae) (Heteroptera: Gerromorpha)

Population density during nymphal development affects body size, developmental rate and wing polymorphism in semiaquatic bugs. Nymphs from crowded habitats grow faster and thus gain an advantage in the later stadia. Rapid development results in smaller body size in several gerrids. Macropterous adults develop more frequently at high population densities in most species, which enables the bugs to leave crowded habitats. Three European widespread species Mesovelia furcata Mulsant & Rey, 1852 (Mesoveliidae), Microvelia reticulata Burmeister, 1835 and Velia caprai Tamanini, 1947 (Veliidae) were reared individually and simultaneously either at a low or high population density. Duration of postembryonic development, wing morph, body size and length of distal oocyte in females were recorded. High population density accelerates development in Mesovelia furcata and Microvelia reticulata. However, there was no trade-off between developmental rate and body size. Accelerated development without a decrease in body size was probably because maturation was delayed. Individually reared nymphs developed faster than nymphs from communal cohorts. No long-winged Microvelia reticulata specimen developed in any treatment. However, more macropterous individuals developed in high-density treatments in Mesovelia furcata (significant) and Velia caprai (not significant). All the nymphs of the species that were reared individually developed into apterous adults. The results suggest that population density strongly influences the life history of semiaquatic bugs. However, the only commonly shared response seems to be an increase in developmental rate when reared at high population densities. Other traits such as wing dimorphism, body size and rate of oogenesis differ at the species level.
Sperm utilization in subadult and adult simultaneous hermaphrodite snails mating in the wild

In species with multiple mating and long-term sperm storage, males are expected to show a preference for mating with virgin and young females to reduce the risk of sperm competition. In various simultaneous hermaphrodite land snail species, sperm production precedes egg production by 2–4 weeks, resulting in a short period of protandric hermaphroditism before shell growth is completed. In a natural population, we collected copulating pairs of the simultaneous hermaphrodite land snail Arianta arbustorum (L., 1758) consisting either of two adults, of two subadults, or of one adult and one subadult snail, and determined the paternity of their hatchlings that emerged from subsequently deposited eggs. Adult snails used sperm received from subadult mating partners for egg fertilization in the same frequency as sperm from adults, indicating that subadult and adult snails do not differ in male function. Furthermore, an unfinished shell is not a reliable indicator for virginity, because 35% of the subadult individu.
Efficiency Performances of Two MPPT Algorithms for PV System With Different Solar Panels Irradiancess

A main source of current renewable energy is solar energy. This source of renewable energy can be converted to electrical energy using solar photovoltaic (PV) cells. The Maximum Power Point Tracking (MPPT) earns for maximum energy extractor from PV panels by different irradiance levels. In this paper, overall efficiency of most two popular MPPT techniques utilized in PV applications are analyzed, these algorithms are Perturb and Observe (P&O) and Incremental Conductance (INC). An analysis of the results for the algorithms based on MATLAB simulation for various changes in solar irradiance is performed. Results showed that the efficiency of P&O algorithm was higher than that of the INC, but to obtain the same performance for both, more concentrated calculations should be used for INC. In measuring the output power, current and voltage responses, the use of a solar array having constant and variable irradiations was employed as input for the algorithms. The output waveforms which were derived from a simulation run for the purpose of obtaining the algorithms response to changes in solar array irradiations were compared. In general, the consequences of the P&O algorithm are quiet good and adequate. However, there is a need to improve the algorithm so as to satisfy the requirements of face confident timing in addition to its rapid response so as to make its performance better than that of InCond algorithms.
Voice-based Age and Gender Recognition using Training Generative Sparse Model

Abstract: Gender recognition and age detection are important problems in telephone speech processing to investigate the identity of an individual using voice characteristics. In this paper a new gender and age recognition system is introduced based on generative incoherent models learned using sparse non-negative matrix factorization and atom correction post-processing method. Similar to general signal classification scheme, our proposed algorithm includes train step to provide related atoms to each signal class and test phase to assess classification performance. Since the classification accuracy depends highly on the selected features, we employ Mel-frequency cepstral coefficients to train basis for better representation of speech structure. These bases are learned over data of male and female speakers using non-negative matrix factorization with sparsity constraint. Then, atom correction is carried out using an energy-based algorithm to decrease coherence between different categories of trained dictionaries. In sparse representation of each data class, atoms related to other sets with the highest energy are replaced with the lowest energy bases if reconstruction error does not exceed from a specified limit. The experimental results show that the proposed algorithm performs better than the earlier methods in this context especially in the presence of background noise.

POWER QUALITY IMPROVEMENT OF A GRID THROUGH DUAL VOLTAGE SOURCE INVERTER

The venture introduces a double voltage source inverter (DVSI) plan to improve the dependability and power nature of the smaller scale lattice framework. The proposed plan is incorporated two inverters, which enables the miniaturized scale matrix to trade control delivered by the appropriated vitality assets (DERs) moreover to reimburse the adjacent nonlinear and uneven load. The control calculations are made in light of immediate symmetrical part hypothesis (ISCT) to work DVSI in framework sharing and lattice implanting modes. The proposed scheme has extended immovable quality, cut down data transfer capacity essential of the essential inverter, cut down cost on account of diminishing in channel size, and better utilization of miniaturized scale lattice control while using reduced dc-interface voltage rating for the key inverter. These segments make the DVSI plot a promising option for miniaturized scale framework providing sensitive weights. The topology and control estimation are endorsed through expansive reenactment and test comes to fruition.
Experimental and Numerical Investigation of Near-field Rotor Aeroacoustics

This work presents comparisons between experimental and numerical estimates of near-field rotor aeroacoustics in hover. The experiments took place at the Kazan National Research Technical University named after A. N. Tupolev (Kazan Aviation Institute). A set of rotor blades with NACA-0012 aerofoil sections was used to obtain the sound pressure distribution using a linear array of microphones. It is shown that CFD and experimental results are in good agreement suggesting that the obtained test data can be useful as a validation case for development of CFD tools.
Hatchery selection promotes boldness in newly hatched brown trout (Salmo trutta): implications for dominance

By using newly hatched (approximately 2 weeks old) brown trout (Salmo trutta) from six families of wild and six families of sea-ranched origin (seventh generation), we tested the hypotheses that (1) the hatchery environment selects for increased boldness, and (2) boldness predicts dominance status. Sea-ranched trout spend their first 2 years in the hatchery before being released into the wild at the onset of seaward migration. Trout were presented with a novel object (tack) and with food (brine shrimp), and their responses were measured and scored in terms of boldness. Siblings with increasing difference in boldness were then paired in dyadic contests. Fish of sea-ranged origin were on average bolder than were fish of wild origin, and bolder individuals were more likely to become dominant regardless of origin. Boldness was not related to RNA levels, indicating that bold behavior was not a consequence of higher metabolism or growth rate. Neither was size a predictor of bold behavior or the outcome of dyadic contests. These results are consistent with studies on older life stages showing increased boldness toward predators in hatchery-selected fish, which suggests that behavioral consequences of hatchery selection are manifested very early in life. The concordance between boldness and dominance may suggest that these behaviors are linked in a risk prone-aggressive phenotype, which may be promoted by hatchery selection. However, we also found significant variation in behavioral and growth-related traits among families, suggesting that heritable variation has not been exhausted by sea-ranching procedures.

Analyzing the Error Propagation in a Parameterizable Network-on-Chip Router

The constant reduction in the components size in integrated circuits and the increase of the operating frequency make Systems-on-Chip (SoCs) more vulnerable to noise and other interference phenomena. Such phenomena can lead to faults, which generate errors that may result in a system crash. SoCs with dozens of cores use Networks-on-Chip as their interconnection architecture. In this context, this work presents an analysis of the error propagation in a parameterizable router architecture that allows different combinations of input and output controllers, data width and buffers depth. The router has been described focusing on design flexibility and low logical resource occupation. We elaborated different combinations of the router architecture and evaluated the error propagation by means of Single Event Upset fault injections. The synthesis results presented a reasonable increase in term of logical elements when applying wider data representations, and combinations using Mealy finite state machines in the routing component had the lowest error propagation rate at a price of a small degradation in the maximum operating frequency.
The elevation training mask induces modest hypoxaemia but does not affect heart rate variability during cycling in healthy adults

This study examined the acute effects of the elevation training mask (ETM) on haemodynamics and heart rate variability (HRV) at rest, during cycling, and during recovery in healthy adults. Fifteen healthy male (N=9) and female (N=6) adults (27.0 ± 1.14 years) completed two trials with the mask (MASK) and without the mask (CON). The 40-minute cycling exercise protocol included 10-minute phases of (1) rest, (2) 50% of VO2peak cycling, (3) 70% of VO2peak cycling, and (4) recovery. Blood pressure and pulse oximetry saturation (SPO2) were measured at each phase. An Actiwave-Cardio ECG monitor (CamNtech, UK) was used to measure HRV variables including time and frequency domains. A greater response in systolic blood pressure (p=.035) was observed at rest while SPO2 (p=.033) was lower during high-intensity cycling (70% of VO2peak) in the MASK trial. The HRV indices were not different between trials during cycling. However, heart rate (p=.047) was greater while inter-beat interval and sympathovagal balance (the ratio between low-frequency and high-frequency components; ln LF/HF, p=.01) were lower in the MASK than the CON trials during recovery. Wearing an ETM during high-intensity cycling (70% of VO2peak) induces modest hypoxaemia. Although this device did not affect HRV changes during cycling, it seems to delay the cardiac-autonomic recovery from exercise. Healthy adults may be required to perform high-intensity exercise with an ETM to simulate a hypoxic environment, but future studies are needed to determine whether repeated exposure to this condition provides similar benefits as altitude training.
The colonial legacy: Income inequality in former British African colonies

This paper examines the distribution of top incomes in 15 former British colonies in Africa, drawing on evidence available from income tax records. It seeks to throw light on the position of colonial elites during the period of British rule. Just how unequal were incomes? How did the position of the rich in the colonies compare with that of the rich in the United Kingdom? It investigates how income concentration evolved in the last years of colonial rule, as the British government became more concerned with development, and establishes the degree of inequality at the time of independence in the late 1950s and early 1960s. What was the colonial legacy? How far did colonial inequality persist post-independence?
Extractive Multi-Document Summarization using Neural Network

Content diagram is a course of action of passing on a rundown by reducing the measure of outstanding document and relating essential information of champion report. There is rising a need to give grand chart in less time in light of the way that in exhibit time, the progress of data increments immensely on World Wide Web or on customer's work zones so Multi-Document once-completed is the best mechanical social affair to impact plot in less to time. This paper demonstrates an audit of existing techniques with the erraticism’s including the need of sharp Multi-Document summarizer.
Molecular evidence for an interfamilial laminarialean cross

When generating kelp hybrid crosses in vitro, small blades are frequently seen in single-sex cultures of microscopic gametophytes as well as in putative hybrid crosses. We demonstrate a polymerase chain reaction (PCR)-based method that quickly determines the presence/absence of possible parental genomes in the observed blades. ITS1 nrDNA fragments that varied in length in a species-specific way were amplified. Amplification products from possible hybrid blades, apogamic blades and parental gametophytes were compared on agarose gels. Using these methods, we were able to identify a number of apogamic blades (i.e. formed directly from gametophytic cells) as well as a true hybrid sporophyte blade in crosses between Alaria marginata (Alariaceae) and Lessoniopsis littoralis (Lessoniaceae), members of two separate families of the Laminariales. To our knowledge this is the first genotypic confirmation of a hybrid kelp.
Routing Algorithm based on Clustering for Increasing the Lifetime of Sensor Networks by Using Meta-Heuristic Bee Algorithms

Nowadays, the use of wireless sensor networks is developing rapidly. these networks are applicable in many fields, including military, medical, and environment. these networks use hundreds or thousands of cheap sensor nodes with low power-low and low energy to perform large tasks. These networks have limitations that can lead to inefficiency or not cost - effective. Among these limitations, consumption of energy and issues related to the lifetime of the network. One of the solutions that can assist the load balancing between sensor nodes, increased scalability, improving energy consumption and consequently, increasing network lifetime, clustering of sensor nodes and placing a suitable cluster head in all clusters. Choosing the right cluster head, significantly reduces energy consumption in the network and increases network lifetime. The purpose of this paper is to increase network lifetime by using the efficient clustering algorithm, which is used in Meta-heuristic bee colony to select the cluster head. Simulation of this paper is performed by MATLB software and the proposed method is compared with LEACH and GACR approaches. The simulation findings in this study show that the intended study has remarkably increased the length of the network lifetime by LEACH and GACR algorithms. Due to the limitation of energy in the wireless sensor network such solutions and using Meta-heuristic algorithms can give rise a remarkable increasing in network lifetime.
