Technological Quality of Dual-purpose Wheat Submitted to Successive Defoliations

Defoliation may interfere in the sink-source relationship and influence grain production and the respective technological quality of wheat flour, particularly in cultivars with potential as forage and in subsequent grain production. This study aimed to determine the effects of plant cutting heights and number of cuttings on the technological wheat flour quality of BRS Umbu and BRS Taruma cultivars. A completely randomized design with four repetitions was used and treatments consisted of a combination of cutting heights (20 and 30 cm) and number of cuttings (no cutting, 1, 2 and 3 cuttings), resulting in the following treatments: 20/1, 20/2, 20/3 30/1, 30/2, 30/3 and controls with no cuttings. Hectoliter weight, grain crude protein, tenacity: extensibility ratio, gluten strength, falling number and wet gluten were measured. Regardless of the cutting height used, and after defoliation, the variables exhibited higher values than in non-defoliated plants, with protein content increasing by 6 and 11.3% for the BRS Taruma and BRS Umbu cultivars, respectively. As such, it can be inferred that defoliation does not negatively affect the technological quality of wheat flour grown in a dual-purpose system.

Introducing the Data Quality Vocabulary (DQV)

The Data Quality Vocabulary (DQV) provides a metadata model for expressing data quality. DQV was developed by the Data on the Web Best Practice (DWBP) Working Group of the World Wide Web Consortium (W3C) between 2013 and 2017. This paper aims at providing a deeper understanding of DQV. It introduces its key design principles, components, and the main discussion points that have been raised in the process of designing it. The paper compares DQV with previous quality documentation vocabularies and demonstrates the early uptake of DQV by collecting tools, papers, projects that have exploited and extended DQV.
Correlation of Serum Markers and Ultrasound Markers in the Prediction of Threatened Miscarriage Outcome

Background: First-trimester bleeding is one of the most common obstetric complications, occurring in 25% of all pregnancies. The clinical diagnosis of threatened miscarriage is presumed when bloody vaginal discharge or bleeding appears through a closed cervical os during the first half of pregnancy. Objective: The aim of the present study was to investigate the relationship between sonographic findings, progesterone level and serum CA-125 in women presenting with symptoms of threatened abortion and first trimesteric pregnancy outcome. Subjects and Methods: This a case-control study included a total of 120 pregnant women between 7- and 13- weeks’ gestation in which a singleton embryo with evident cardiac activity was initially documented completed the study, attending at Gynecological and Obstetric Department in Zagazig University Hospital and Mit Ghamr General Hospital. This study was conducted between July 2016 to February 2018. Results: There was no significant difference among groups in CRL and GSD but YSD was significantly higher among cases. CA 125 was significantly higher in actual miscarriage with a level 47.9IU/ml (±31.52) between those who had actual miscarriage before 13 weeks and 17.4IU/ml (±10.67)between those who continued pregnancy after 13 weeks while progesterone showed level 11.1ng/ml (±10.38)between those who aborted before 13 weeks and a level of 11.6ng/ml (±6.19) between those who continued. GSD and YSD significantly higher in actual miscarriage as the mean was 51.4mm (±18.56) and 6.73mm (±0.6) respectively for those who aborted and 38.52mm and 6.11mm respectively for those who continued pregnancy. Conclusion: The use of ultrasound and maternal serum CA-125in the first trimester represents non-invasive, early and fast methods that can be considered as a good predictor for the outcome of pregnancy in cases with threatened abortion.

Many business intelligence tools aim to digest data into easy, understandable and visualizable information for helping decision-making, while they are still lack of ability to support visualizing the history of selections. This limitation concerns the coming future when everything is about data. Due to it, users are not able to share their thinking paths to the decision. Here a history selection path means a sequence of previous selections. As an approach, it helps users in decision-making and discovery insight. This study investigated an efficient graphical visualization system of history selection paths to support communicating and iterative analysis. We selected tree representation as the main visualization model and also propose features needed for the system. Specifically, we researched the significance of this study, existing solutions and also the proper designs and functions for the idea. It is initiated by user research including targeting users and scenario mapping. Based on the understanding, we applied a parallel design to narrow down the suitable design. As a result, tree representation was selected as the visualization model. To evaluate whether it touched user needs or not, we applied usability test to collect quantitative data and qualitative comments. For making the test environment as real as possible, a webbased interactive prototype supported by D3.js library was implemented for testing. We analyzed the user experience and also consolidated improvements. As a case study, we implemented the solution on Qlik Sense to verify the possibility to place this solution into real data visualization tool. Generally, the result of this study formed a valuable initiative for further development and we saw potentials of this tree model system to be used in other areas when it comes to reviewing history as well.
Autonomous Navigation of Unmanned Aerial Vehicles based on Android Smartphone

In the past few years, the adoption of drone technology across industries has increased dramatically as more businesses started to recognize its potential, uses, and scale of global reach. This paper proposes a design solution of a smart GPS quadcopter aircraft navigation system, discusses its hardware and software implementation process and eventually, analyses and reports the final test results. The flight path of the quadrotor is remotely manipulated via an Android based Graphical User Interface. This outdoor handheld application al-lows the operator to select a point of interest through Google map satellite view; consequently, the quadrotor takes off then hovers and ultimately lands on the destination location. Instructions in conjunction with coordinates are sent and received throughout a web server which serves the communication operation between the smartphone and the quadrotor. Experimental results yield fruitful data communication and successful autonomous flight control with smooth and stable maneuvering.
Association of Common Variants in HNF1A Gene with Serum AFP Level in Healthy Chinese Individuals and HCC Patients

Although alpha-fetoprotein (AFP) is a widely used tumor marker in hepatocellular carcinoma (HCC), 40% of newly diagnosed patients do not have an elevated AFP level. Research has revealed that mutations in the HNF1A binding site of the AFP gene promoter cause significantly elevated serum AFP levels in patients with hereditary persistence of AFP. This study investigated the relationship between HNF1A genetic variants and serum AFP levels. We examined the association between the HNF1A-rs1169288 (A/C), rs2464196 (G/A), and rs1169310 (C/T) polymorphisms and AFP levels in a healthy Chinese population (n = 1010) and HCC patients (n = 185). Single nucleotide polymorphisms were genotyped by the amplification refractory mutation system combined with TaqMan probe in real-time PCR. The serum AFP concentrations were measured using the Architect i2000 immunochemistry analyzer. In healthy individuals, serum AFP levels were significantly lower with the rs2464196-AA and rs1169310-TT genotypes. Similar significant differences were observed in HCC patients. Moreover, in HCC patients, the distribution frequencies of rs2464196-AA+AG and rs1169310-TT+TC among those with AFP ≤ 20 ng/ml or ≤400 ng/ml were significantly lower than those in patients with AFP > 20 ng/ml or >400 ng/ml. Among all subjects, those carrying the HNF1A-rs2464196-A or rs1169310-T allele tended to have low levels of AFP. However, the HNF1A-rs1169288 polymorphism showed no significant association with the serum AFP level. These findings provide new insight into the genetic determinants of serum AFP level and can aid the differential diagnosis of HCC patients with low serum AFP.
An Overview on Synthesis Techniques for Near-Field Focused Antennas

Microwave and millimeter-wave antennas focused in their radiative near-field (NF) region, which are usually named as near-field focused (NFF) antennas, are becoming increasingly popular. Indeed, when compared to conventional far-field focused antennas, they can guarantee performance improvement at a relatively limited implementation cost, in short-range communication systems, wireless power transfer arrangements, remote nondestructive sensing setups, and radio-frequency identification apparatus, among many others. In this chapter, application fields and metrics for NFF antennas will be briefly summarized. Most of the chapter is then devoted to the description, classification, and critical review of the many synthesis techniques that go beyond the simple, yet effective and with a clear physical insight, conjugate-phase approach.
Backtransforming Rank Order Kriging Estimates

Kriging of raw data presenting distributions with positive skewness must be avoided because the strong influence of a few high values in the resulting estimates. The solution is to apply data transformation, which changes the shape of original distribution into a symmetric distribution. Kriging of transformed data is performed and then back-transformed to the original scale of measurement. In this paper, we examine the uniform score transform that results in a uniform distribution. Ordinary kriging estimates of uniform score data results in a bell-shaped distribution, since the tails of the distribution are lost in the estimation process because of the smoothing effect. The back-transformation of this bell-shaped distribution result in biased estimates. Therefore, the solution proposed in this paper is to correct the smoothing effect of the rank order kriging estimates before transforming them back to the scale of raw data. Results showed this algorithm is reliable and back-transformed estimates are unbiased in relation to the sample data.

DISSECTOR: Input Validation for Deep Learning Applications by Crossing-layer Dissection

Deep learning (DL) applications are becoming increasingly popular. Their reliabilities largely depend on the performance of DL models integrated in these applications as a central classifying module. Traditional techniques need to retrain the models or rebuild and redeploy the applications for coping with unexpected conditions beyond the models' handling capabilities. In this paper, we take a fault tolerance approach, Dissector, to distinguishing those inputs that represent unexpected conditions (beyond-inputs) from normal inputs that are still within the models' handling capabilities (within-inputs), thus keeping the applications still function with expected reliabilities. The key insight of Dissector is that a DL model should interpret a within-input with increasing confidence, while a beyond-input would probably cause confused guesses in the prediction process. Dissector works in an application-specific way, adaptive to DL models used in applications, and extremely efficiently, scalable to large-size datasets from complex scenarios. The experimental evaluation shows that Dissector outperformed state-of-the-art techniques in the effectiveness (AUC: avg. 0.8935 and up to 0.9894) and efficiency (runtime overhead: only 3.3-5.8 milliseconds). Besides, it also exhibited encouraging usefulness indefensing against adversarial inputs (AUC: avg. 0.9983) and improving a DL model's actual accuracy in use (up to 16% for CIFAR-100 and 20% for ImageNet).
Photocatalytic Degradation of Methylene Blue using Zinc Oxide Synthesized by Hydrothermal Method

ZnO nanoparticals (ZnO-NPs) were synthesized by hydrothermal method at low temperatures over a range of different hydrothermal time periods and different calcination temperatures. The synthesized ZnO-NPs were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and nitrogen adsorption-desorption isotherms (BET). The XRD results showed that all ZnO-NPs were hexagonal wurtzite phase. The photocatalytic activities of the ZnO-NPs were tested through the degradation of methylene blue under UV light. The highest methylene blue (MB) degradation was found to be 99% with zinc oxide synthesized at 48 hours hydrothermal process time and 300 &deg;C calcination temperature conditions during 3 hours degredation time. As a result, the synthesized by hydrothermal method at low temperatures ZnO-NPs have potential applications in the treatment of wastewater.
Impact of FDI on Economic Growth in Developing Countries: Role of Human Capital

Economic theory proposes that FDI is one of the primary driving forces for stimulating growth (Barro and Sala-i-Martin, 1995). Researchers still debate whether the interpretation of the direct effect of FDI on economic growth is inconclusive, whereas the significance of the absorptive capacity of host countries is commonly emphasized (e.g., Borensztein, De Gregorio, and Lee 1998; De Mello Jr. 1999; Alfaro et al. 2004; Makki and Somwaru 2004; Gönel and Aksoy 2016). Such uncertainty may be the result of ignoring the effect of certain conditioning variables. This study aims to empirically explore whether FDI contributes to economic growth and whether the effect varies with the human capital development level in a panel data set of 70 developing economies from 1980 to 2015. The study employs the General Methods of Moments estimation instrumental variable technique to deal with the endogeneity issue. The empirical investigation shows that human capital threshold exists above which FDI exhibits a positive impact and below where it shows a detrimental effect on economic growth. Findings may help policymakers in selected developing countries to take advantage of the increasing international investment by considering domestic human capital development level.
Maintaining satisfactory performance of expatriates: The effects of culture and conflict management style

The study presents a conceptual framework that links culture (that is, power distance, individualism, uncertainty avoidance, and masculinity), and conflict management styles (that is, problem-solving, compromising, forcing, and legalistic), to identify their impact upon satisfaction of expatriates and their job performance. The sample size comprised of 193 Japanese senior managers working in Taiwan. LISREL 8.52 was used to assess the relationships among these variables. The results demonstrated that: (1) higher individualism is related to compromising and legalistic styles; (2) uncertainty avoidance is negatively related to problem-solving and positively related to forcing styles; (3) masculinity is positively associated with problem-solving and negatively associated with forcing styles; (4) performance satisfaction is negatively related to problem-solving, legalistic, and masculinity but positively related to individualism.
BACHELOR THESIS FINANCE The effect of stock splits announcements during and after a financial crisis

There are plenty of studies that have documented positive abnormal results when stock splits are announced by companies. In addition, there are several theories that explain these results, like the signallingand trading range hypothesis. In this thesis, I looked if there are still positive abnormal returns around stock splits during a negative time, like the financial crisis of 2008 and if we find similar results after that period. I analysed the cumulative average abnormal returns of 351 stock splits, with the market model and the market-adjusted model, for the periods 2007-2011 and 2012-2016. I found that the market reacts negatively to stock split announcement after the financial crisis period, but reacts positive during the financial crisis depending on the model being used. The views stated in this thesis are those of the author and not necessarily those of Erasmus School of Economics or Erasmus University Rotterdam.
End-to-end Learned, Optically Coded Super-resolution SPAD Camera

Single Photon Avalanche Photodiodes (SPADs) have recently received a lot of attention in imaging and vision applications due to their excellent performance in low-light conditions, as well as their ultra-high temporal resolution. Unfortunately, like many evolving sensor technologies, image sensors built around SPAD technology currently suffer from a low pixel count. In this work, we investigate a simple, low-cost, and compact optical coding camera design that supports high-resolution image reconstructions from raw measurements with low pixel counts. We demonstrate this approach for regular intensity imaging, depth imaging, as well transient imaging. Our method uses an end-to-end framework to simultaneously optimize the optical design and a reconstruction network for obtaining super-resolved images from raw measurements. The optical design space is that of an engineered point spread function (implemented with diffractive optics), which can be considered an optimized anti-aliasing filter to preserve as much high-resolution information as possible despite imaging with a low pixel count, low fill-factor SPAD array. We further investigate a deep network for reconstruction. The effectiveness of this joint design and reconstruction approach is demonstrated for a range of different applications, including high-speed imaging, and time of flight depth imaging, as well as transient imaging. While our work specifically focuses on low-resolution SPAD sensors, similar approaches should prove effective for other emerging image sensor technologies with low pixel counts and low fill-factors.
Coupled Eulerian-Lagrangian (CEL) Modeling of Material Flow in Dissimilar Friction Stir Welding of Aluminum Alloys

In this work, the finite element simulation of dissimilar friction stir welding process is investigated. The welded materials are AA 6061-T6 and AA 7075-T6 aluminum alloys. For this purpose, a 3D coupled thermo-mechanical finite element model is developed according to the Coupled Eulerian-Lagrangian (CEL) method. The CEL method has the advantages of both Lagrangian and Eulerian approaches, which means it can simultaneously solve the singularity in the large deformation problems and describe the physical boundary of the material accurately. In this paper, the effects of the position of the harder material (AA 7075-T6 aluminum alloy) and the tool pin profile on the temperature distribution and material flow in the weld metal and heat affected zone (HAZ) are investigated. The results show that the material velocity around the FSW tool is found to be higher using a grooved pin profile. Moreover, placing the harder material at the advancing side results in slightly lower process temperatures in comparison to the estimated temperature when the material is placed at the retreating side for all types of tool profiles. It has been proved that if the AA 7075-T6 aluminum alloy is at the advancing side, mixing happens in a thin layer below the tool shoulder, and the penetration of the harder material into the retreating side is found to be limited. In addition, good agreement between the temperature distribution obtained from the experimental measurements and numerical simulations is achieved and the accuracy of the numerical model is confirmed.

Objective To study the expression and mechanism of mast cells (MCs) in complete Freund’s adjuvant(CFA)-induced inflammatory pain in rats. Methods Seventy male adult SD rats were randomly divided into 4 groups (A,B,C,D) and were given normal saline(A and C group) or 0.1% CFA(B and D group) 50 μl by subcutaneouly (s.c.) injection in ankle joint of right hind limb. To measure the hyperalgesia with the latency of paw withdrawal from a noxious thermal stimulus(thermal withdrawal la- tency,TWL) prior to pre-injection and 1 h,4 h,12 h,1 d,3 d,7 d,9 d,14 d after s.c. injection in A and B groups, toluidine blue(TB) staining was used to detect the total numbers and the morphology changes in peripheral MCs in C and D groups at above time point. Results (1)Compared with group A, TWL in group B shorten significantly at the 4th hour(P0.01), achieved valley-bottom at the 12th hour(P0.01) and improved gradually since the 3th day, restored to the initial level on the 14th day (P0.05);(2)In group D, the total numbers of MCs increased obviously at the first hour (P0.01), reached the peak on the 7th day, then decreased slowly, and significantly higher than that in group C on the 14th day (P 0.01); Compared with group C, the number of degranulated MCs were obviously higher at the first hour (P0.01), reached the peak at the 12th hour(P0.01), kept the peak time from the 4th to 24th hour then restored to the initial level on the 14th day (P0.05). Conclusion CFA can induce inflammatory hy- peralgesia for two weeks, the mast cells initiates and participates in the process and maintain of inflam- matory pain.
INVESTIGATION OF REVERSE TAPER TO OPTIMIZE THE DEGREE OF POLARIZATION FOR THE DELTA UNDULATOR AT THE LCLS

A 3.2 m adjustable phase Delta undulator will soon be installed on the last girder of the LCLS undulator line. The Delta undulator will act as an afterburner terminating the 33 undulator line, providing arbitrary polarization control to users. Two important figures of merit for users will be the degree of polarization and the x-ray yield. In anticipation of this installation, machine development time at the LCLS was devoted to maximizing the final undulator x-ray contrast and yield with a standard canted pole planar undulator acting as a stand in for the Delta undulator. Following the recent suggestion [1] that a reverse taper in the main undulator line could suppress linearly polarized light generated before an afterburner while still producing the requisite microbunching, we report on a reverse taper study at the LCLS wherein a yield contrast of 15 was measured along the afterburner. We also present 1D simulations comparing the reverse taper technique to other schemes.
