Miniaturised Asymmetrical E-Shaped Patch Antenna With Circular Polarisation

Abstract should be times This paper includes the simulation and design parameter microstrip E-shaped patch antenna, demonstrating different operating frequencies. In this study three unequal resonance arms are fed by probe feed to the folded patch in order to increase the impedance bandwidth. The miniaturisation of the size of patch is done by the application of shorting pins . The performance of broadening the impedance bandwidth is explored by investigating the behavior of surface currents in patch. The tuning resonance ability of antenna is present within the impedance bandwidth by varying the length of unequal resonance arms. For ultra-wideband applications the measured -10 dB impedance bandwidth of fabricated antenna is 76.18% from 3.34 to 7.45 GHz. The size of the antenna is 0. 379λL × 0. 145λL × 0.078 λL, where λL is wavelength at the lower frequency of measured operating bandwidth in the free space. It is designed by air substrate which has a dielectric constant of 1.0006. In addition to this, parametric studies are done by investigating the effect of different key parameters on obtaining an optimal design of the proposed antenna design.
'One is Known by the Company One Keeps': Imprinting Effects of a Firm's Network Entry on its Future Status

Given the importance of network status, this study seeks to understand how newcomers - young organizations entering inter organizational networks - attain such privileged positions. Drawing on literature in imprinting and network theory, we develop a model and hypotheses regarding the direct and moderating effects of the newcomer's ego-network characteristics in the year of network entry on its status, and examine their persistence over time. We test proposed relationships on a panel data of 411 U.S. venture capital firms (3,627 observations) and show that with some diminishing returns over time, the characteristics of initial partnerships exert a long term influence on newcomer's status.
Does Southern Ocean Surface Forcing Shape the Global Ocean Overturning Circulation?

Paleoclimate proxy data suggest that the Atlantic Meridional Overturning Circulation (AMOC) was shallower at the Last Glacial Maximum (LGM) than its preindustrial (PI) depth. Previous studies have suggested that this shoaling necessarily accompanies Antarctic sea ice expansion at the LGM. Here the influence of Southern Ocean surface forcing on the AMOC depth is investigated using ocean‐only simulations from a state‐of‐the‐art climate model with surface forcing specified from the output of previous coupled PI and LGM simulations. In contrast to previous expectations, we find that applying LGM surface forcing in the Southern Ocean and PI surface forcing elsewhere causes the AMOC to shoal only about half as much as when LGM surface forcing is applied globally. We show that this occurs because diapycnal mixing renders the Southern Ocean overturning circulation more diabatic than previously assumed, which diminishes the influence of Southern Ocean surface buoyancy forcing on the depth of the AMOC.
Overexpression of TIGAR predicts poor prognosis in elderly patients with cytogenetically normal acute myeloid leukemia ( CN-AML )

Background: Elderly patients with acute myeloid leukemia (AML) have poor clinical outcomes and cytogenetically normal (CN)-AML shows great heterogeneity. Leukemic cells exhibit increased aerobic glycolysis. TP53induced glycolysis and apoptosis regulator (TIGAR) decreases glycolysis and correlates with tumor survival. The objectives of this study were to investigate TIGAR expression in elderly patients with de novo CN-AML and correlate the results with clinical features and outcomes. Patients and Methods: We explored the expression of TIGAR by real-time quantitative PCR and its correlation with other prognostic factors, overall survival (OS) and disease-free survival (DFS) in 75 elderly patients with de novo CN-AML. Results: No significant differences were observed between patients with high and low expression of TIGAR for most clinical features, while patients with low expression of TIGAR were more prone to have high incidence of CEBPA mutations (P=0.0383). Patients with low expression of TIGAR had significantly longer OS (P=0.0054) and DFS (P=0.0124) compared to patients with high expression of TIGAR. The overexpression of TIGAR was associated with a significantly higher relapse rate (P=0.0138) and cumulative incidence of relapse (P=0.004). A multivariate analysis revealed that high TIGAR expression was associated with shorter OS (P=0.029) and DFS (P=0.045). Conclusion: Our study identified that the overexpression of TIGAR was closely correlated with worse clinical outcome in elderly patients with CN-AML, suggesting that TIGAR may be an independent prognostic factor and a therapeutic target of this devastating and heterogenetic malignancy.
Evaluating Real Estate Mutual Fund Performance Using the Morningstar Upside/Downside Capture Rati

The purpose of this research is to explore the viability of utilizing the Morningstar upside/downside capture ratio (UDCR) as viable measure of mutual fund risk and its relation to return. This research examines and compares result of the Sharpe ratio to the Morningstar upside/downside capture ratio (UDCR) in an effort to determine if the UDCR might better explain the ex-post performance of the mutual funds examined. Three sectors of 268 mutual funds are examined; these include domestic equity real estate, domestic equity value funds, and global equity real estate as defined and reported on the Morningstar database. This research considers the traditional measures of risk which include the standard deviation of returns along with the Sharpe ratio. The empirical results suggest that UDCR may provide a more accurate fit in explaining real estate mutual fund returns than the Sharpe Ratio
Performance of specialist and generalist herbivores feeding on cabbage cultivars is not explained by glucosinolate profiles

Plants display a wide range of chemical defences that may differ in effectiveness against generalist and specialist insect herbivores. Host plant‐specific secondary chemicals such as glucosinolates (GS) in Brassicaceae typically reduce the performance of generalist herbivores, whereas specialists have adaptations to detoxify these compounds. The concentration of glucosinolates may also alter upon herbivory, allowing the plant to tailor its response to specifically affect the performance of the attacking herbivore. We studied the performance of three Lepidoptera species, two specialists [Pieris rapae L. (Pieridae), Plutella xylostella L. (Yponomeutidae)] and one generalist [Mamestra brassicae L. (Noctuidae)], when feeding on eight cultivars of Brassica oleracea L. and a native congener (Brassica nigra L.) and related this to the GS content. We tested the hypotheses (i) that a generalist herbivore is more affected by high GS concentrations, and (ii) that generalist feeding has a stronger effect on GS levels. Although performance of the three herbivores was different on the B. oleracea cultivars, M. brassicae and P. xylostella had a similar ranking order of performance on the eight cultivars. In most of the cultivars, the concentration of indole GS was significantly higher after feeding by P. rapae or M. brassicae than after P. xylostella feeding. As a consequence, the total concentration of GS in the cultivars showed a different ranking order for each herbivore species. The generalist M. brassicae performed equally well as the specialist P. xylostella on cultivars with high concentrations of GS. Our findings suggest that secondary metabolites other than GSs or differences in nutrient levels affect performance of the species studied.
The relationship between forest fragmentation and the potential geographical distribution of psittacids (Psittaciformes: Psittacidae) in the Yucatan Peninsula, Mexico

Parrots are a seriously threatened group because of the illegal pet trade, their habitat fragmentation and the destruction of tropical forests. This study aimed to determine the relationship between forest fragmentation and the geographic potential distribution of parrot species in the Yucatan Peninsula, Mexico. The research was carried out in the Mexican portion of the Yucatan Peninsula Biotic region, which includes the states of Campeche, Quintana Roo and Yucatan. We worked with the eight species of psittacids that inhabit the selected areas: Eupsittula nana , Amazona albifrons , Amazona xantholora , Amazona autumnalis , Pionus senilis , Pyrilia haematotis , Amazona oratrix and Amazona farinosa . For these species, we used the potential geographical distribution maps that were obtained through the Maximum Entropy algorithm, published in 2014. To measure the levels of forest fragmentation in the Peninsula, we employed the land use and vegetation maps from series IV (2007-2010) of the National Institute of Statistics and Geography. We calculated different landscape metrics at 100 sites randomly distributed within the predicted presence and absence areas for the species. Multivariate methods were used to shorten dimensionality in the analysis, as well as to explore the observed patterns. We did not find any pattern regarding the number of variables that contribute to the logistic regression models (LR) and the size of the parrots’ potential geographical distribution area within the Peninsula. For Pyrilia haematotis and Amazona oratrix , the fragmentation variables used did not seem to have any relationship with their potential geographical distribution in the Peninsula (intersection, Pr < 0.0001). Only for Eupsittula nana , Amazona xantholora and Pionus senilis, we found that the mean patch edge, the mean shape index and the mean perimeter-area ratio were important to determine their potential distribution patterns, respectively; and, in general, the variables indicated the preferences of these parrots to occupy larger habitat patches. Parrots must be given a special care and protection within the states of Campeche and Quintana Roo, since there are areas with high parrot diversity and are importantly affected by human activities. The best recommendation for managers and users of protected areas within the Yucatan Peninsula is that extensive areas of forest should be maintained in order to guarantee the suvival of psittacid populations.
Yield and quality of fruits of strawberry cultivars in an organic production system

Most works on strawberry refer to conventional production systems and in traditional regions, so there is little scientific knowledge for its cultivation in other conditions, such as in the organic production of northwestern RS, Brazil. The objective of this work was to evaluate the productive aspects and physicochemical characteristics of strawberry cultivars grown in an organic production system in the northwest of RS. The experiment was carried out at the Cerro Largo Campus of the Federal University of the Southern Frontier between June 2013 and January 2014. The experimental design was a randomized block design with six blocks composed of three experi­mental units. Each unit consisted of 20 plants arranged in four interspersed lines, with plants spaced 0.30 m apart. Three strawberry cultivars were compared: Albion, Aromas and San Andreas. Yield variables were determined by mass, number, volume of pseudofruits and production percentage of non-marketable pseudofruits. Quality was determined from soluble solids content (SS), titratable acidity (TA), SS/TA ratio and pH. The cultivars Aromas and Albion were the most adapted to the organic production system under the conditions determined in this work.
A novel high-speed ring oscillator for multiphase clock generation using negative skewed delay scheme

A high-speed ring oscillator is proposed for improved operation frequency over those based on the conventional n-stage inverter chain. The ring oscillator consists of inverters with negative delay elements that are derived from the ring oscillator circuit. The cell delay of the ring oscillator is smaller than a fundamental inverter delay. Simulations show that the resulting operating frequencies are 50% higher than those obtainable from the conventional approaches.

In these notes we survey some new results concerning the ρ-variation for singular integral operators defined on Lipschitz graphs. Moreover, we investigate the relationship between variational inequalities for singular integrals on AD regular measures and geometric properties of such measures. An overview of the main results and applications, as well as some ideas of the proofs, are given.
Biology of dubas bug, Ommatissus lybicus (Homoptera: Tropiduchidae), a pest on date palm during spring and summer seasons in Panjgur, Pakistan

Dubas bug, Ommatissus lybicus is one of the major sucking pests of date palm. Both nymphs and adults suck the sap from fronds and fruit stalks. Severe infestations cause even death of date palms. Biological parameters of the bug were studied for the four consecutive generations on Kehraba cultivar during spring and summer seasons 2009-2010. The mean fecundity and longevity of male adults of first (spring) generation were significantly lower than that of second (summer) generations 2009-2010. Mean egg laying frequency, adult longevity, incubation and post ovipositional period during 1 st and 2 nd generation were 4.90, 19.50, 147.60 and 3.60; and 5.30, 21.80, 62.70 and 4.50 days, respectively. The mean nymphal development periods were 46.9 and 49.6 days in spring and summer generations with no significant difference. On the average, females have longer life duration (27.85 days) than males (18.85 days) under the similar climatic conditions and generations. This bivoltine hibernates and aestivates in the egg stage in fronds during winter and summer and on an average completes total life cycle of 1 st and 2 nd generation in 217.25 and 136.35 days, respectively. Dubas bug passes 61.43 and 38.56 % time of life cycle in eggs stage during spring and summer generations, respectively.
Targeted inhibition of miR-340 on β-catenin to potentiate Adriamycin sensitivity of osteosarcoma Saos-2 cells

Wnt/β-catenin pathway regulates cell proliferation and apoptosis via facilitating Survivin transcription. Over-expression of β-catenin is correlated with osteosarcoma onset and drug resistance. MiR-340 is down-regulated in osteosarcoma, and has targeted relationship with 3’-UTR of β-catenin. This study investigated the role of miR-340 in regulating β-catenin expression, and affecting osteosarcoma Saos-2 cells drug resistance to Adriamycin (ADM). MiR-340 and β-catenin expression was compared between Saos-3 and hFOB1.19 cells. Dual luciferase gene reporter assay demonstrated regulatory relationship between miR-340 and β-catenin. ADP-resistant cell line Saos-2/ ADM1.0 and Saos-2/ADM4.0 was generated for quantifying miR-340, β-catenin and Survivin expression. Drug resistant index was calculated and compared. 4.0 mg/L ADM was used to treat Saos-2/ADM4.0 cells, which were then treated with miR-340 mimic and/or si-β-catenin. Cell expression of β-catenin and Survivin, and cell proliferation/ apoptosis were compared. Saos-2 cells had lower miR-340 and higher β-catenin expression compared to hFOB1.19 cells. A targeted regulation relationship existed between miR-340 and β-catenin. MiR-340 expression in Saos-2/ ADM4.0 (RI=44.528) and Saos-2/ADM1.0 (RI=21.937) cells was lower than Saos-2 cells, whilst β-catenin and Survivin expression was higher. Transfection of miR-340 mimic and/or si-β-catenin lowered β-catenin and Survivin expression, weakened cell proliferation potency, and increased ADM-induced apoptosis. MiR-340 can decrease Saos-2 cell proliferation, elevate apoptosis and ADM sensitivity via targeted inhibition on β-catenin and downstream anti-apoptotic protein Survivin expression.
Algal biomass and pigment diversity in typical tropical fish ponds

Chlorophyll distribution, phytoplankton biomass and pigment diversity were investigated at fortnightly intervals, in eight fish ponds located in Ile-Ife, Nigeria. Except for stations 6 and 7, the diatoms were the most prominent phytoplankton group while the chlorophyceae were less prominent. Peak periods of chlorophyll-a coincided with peak periods of nutrient availability and generally, the stations recorded high algal biomass. Margalef Index (M.I.) ratios were negatively correlated with both gross and net production while the latter were positively correlated with chlorophyll-a but negatively correlated with chlorophylls b and c. In terms of phytoplankton diversity, station 7 recorded the least number of species while the maximum number was recorded in station 4.
3 Subtasks and Data Description SemEval-2019 Task 8 has two subtasks : • Subtask

We present SemEval-2019 Task 8 on Fact Checking in Community Question Answering Forums, which features two subtasks. Subtask A is about deciding whether a question asks for factual information vs. an opinion/advice vs. just socializing. Subtask B asks to predict whether an answer to a factual question is true, false or not a proper answer. We received 17 official submissions for subtask A and 11 official submissions for Subtask B. For subtask A, all systems improved over the majority class baseline. For Subtask B, all systems were below a majority class baseline, but several systems were very close to it. The leaderboard and the data from the competition can be found at http://competitions.codalab. org/competitions/20022.
655 Weak-Constraint and Long-Window 4 D-Var

We describe recent progress in weak-constraint and long-window 4D-Var. Experiments in a two-layer quasi-geostrophic system confirm the results obtained by Fisher et al. (2005) for the Lorenz (1995) model. The experiments show that increasing the length of the analysis window in 4D-Var improves the analysis. Moreover, this benefit is present even if the model error is induced by systematic error in the model parameters, and is imperfectly described by the analysis system. We present results using the full ECMWF analysis system showing that the analysis window can usefully be extended to 24 hours. It is expected that 24 hour 4D-Var will be implemented in 2012. We also present results using a degraded observation network comprising surface pressure observations only. We find that a 24-hour analysis window gives better results than a 12-hour analysis window, and the improvement is even more significant when the 24-hour windows are “overlapped” by performing an analysis every 12 hours. The importance of properly taking into account the mean component of model error is highlighted in both the two-layer quasi-geostrophic context, and in experiments conducted using an Reanalysis configuration of the ECMWF assimilation system in which only historical surface pressure observations are assimilated. A major potential benefit of weak-constraint 4D-Var is that it allows parallelisation of the inner loops of 4D-Var. We discuss how this benefit might be realised, and present a new parallel algorithm which we call the “saddle point” formulation of 4D-Var. We demonstrate the algorithm using the two-layer quasi-geostrophic system. Technical Memorandum No. 655 1 Weak-Constraint and Long-Window 4D-Var
EFFECT OF BRINE CONSTITUENTS ON THE CONTENT AND PROPERTIES OF WATER IN THE PORCINE MUSCULUS LONGISSIMUS DORSI

A b s t r a c t . The capacity to bind water exerts a cruci al influence on the quality of cured products manufactured from whole muscles and subjected to thermal treatment. The experimental material comprised the lumbar and thoracic parts of the longissimus dorsi (musculus longissimus lumborum et musculus longissimus thoracis) muscle of pigs. The aim of the performed experiments was to analyse the impact of different composition of brines which con tained a specific quantity of salts of inorganic ac ids on the value of active acidity, water activity, water holding capacity and the way of water binding. It w as found that both parts of raw longissimus dorsi muscle differed with regard to the pH value, water activity and molecular dynamics of bound water. The water holding capacity as well as the mutual relationships between the quantities of free and bound waters wer e identical. The type of the applied brine exerted some influence on the level of water holding capacity. T he relative amount of free water in relation to bou nd water analysed on the basis of relaxation measurements was the highest when the mixture of sodium chloride and sodium triphosphate was applied. The mixture of chloride and sodium diphosphate reduced the relative content of free water in relation to b ound water in comparison with the application of br ine which contained only NaCl and increased it in comparison with the application of diphosphate. The pres ence of sodium chloride increased water activity, w hile the presence of phosphates decreased this para meter. The lumbar part of the examined muscle showed higher water activity. The application of the salt mixture did not change the value of water activity in comparison with NaCl alone for the lumbar part but increased water activity for the thoracic part of t he muscle.

Colored Wheat: Anthocyanin Content, Grain Firmness, Dough Properties, Bun Texture Profile

KRÁL MARTIN, POKORNÁ JANA, TREMLOVÁ BOHUSLAVA, OŠŤÁDALOVÁ MARTINA, TROJAN VÁCLAV, VYHNÁNEK TOMÁŠ, WALCZYCKA MARIA. 2018. Colored Wheat: Anthocyanin Content, Grain Firmness, Dough Properties, Bun Texture Profile. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 67(3): 685 – 690. The aim of this study was to determine the total anthocyanin content and firmness of three spring wheat varieties Triticum aestivum L. (Vanek, UC66049 and Konini) and evaluate the relationship between its flour and texture parameters of the dough and bun. Total anthocyanin content in grain varieties varied from 6.70 to 47.63 mg.kg–1. In colored wheat was observed approximately seven times more content compared with the control. The highest firmness was obtained in purple (27.62 N) and the lowest in blue grain (22.31 N). The lowest stickiness was found in blue wheat dough and therefore, it would be more suitable for manufacturing. Blue wheat decreased the dough cohesiveness and work of adhesion. The crumb hardness was significantly lowest in blue batch (P < 0.01) in 100 and 90 % concentration and in 80 % mixture was control significantly highest (P < 0.01). The lower addition of colored wheat flour increased bun springiness. In 100 % and 90 % concentrations were highest values of gumminess observed in purple batch and lowest in blue, but in 80 % concentration was control highest and purple batch was lowest and the same tendency was observed in bun chewiness.
