ANALYSIS OF HEXANE EXTRACTS OF CORN HYBRIDS ANALIZA HEKSANSKIH EKSTRAKATA BRAŠNA HIBRIDA KUKURUZA

Groups of corn hybrids with common genetic constitutions were analyzed. The lipid compounds from 13 samples of corn flour were extracted with n-hexane. Trimethylsulfonium hydroxide (TMSH) was applied for derivatization of fatty acids into volatile methyl esters. Derivatized extracts were analyzed by GC-MS.Simplified SIM chromatograms were extracted from TIC chromatograms by selecting the ion 74 m/z, which is characteristic only for lipid components. By using cluster analysisof the peak areas of lipid sub-stances a dendrogram was obtained. It was observed that the best separation among corn hybrids can be achieved by introducing automatic integrated areas of peaks from third part of the chromatograms (lipid components that elute after 14.25 min) in multivariate analysis. However, it was also observed that samples of corn hybrids are grouped into clusters independently from their corresponding genetic constitution, no matter which part of the chromatogram is to be applied in cluster analysis.
A Balanced Butter�y Optimization Algorithm For Numerical Optimization And Feature Selection

Butterfly optimization algorithm (BOA) is a relatively novel optimization technique for solving function optimization as well as real world applications. However, the paramount challenge in BOA is that it is prone to stagnation in local optima. The purpose of this study is to balance the exploration and exploitation abilities of BOA when two new strategies are introduced. The dynamic inertia weight based on Logistic model as the first strategy is introduced to modify the position updating equation. Another strategy is the opposition-based learning. A new variant of BOA called BBOA based on these two strategies is proposed. Ten widely used benchmark test functions and 30 complex benchmarks from CEC 2014 are selected to verify the effectiveness of BBOA. The used benchmark problems are composed of unimodal, multimodal, rotated, shifted, hybrid and composite functions. The experimental results and analysis show that the proposed BBOA has better exploration ability than the conventional BOA when solving different characteristics functions. Finally, BBOA is applied to solve three real-world engineering applications and sixteen feature selection problems. The results demonstrate that BBOA can outperform other competitors in terms of the accuracy of solution on constrained engineering design and feature selection problems.
FinFET-based Miller encoder for UHF and SHF RFID application

ABSTRACT This paper proposes a T-flip-flop and a Miller encoder design for ultra-high frequency and super high frequency, radio-frequency identification (RFID) application using FinFETs. Miller encoder is used in magnetic recording, in optical domain and also in RFID. Performance of the proposed circuit was examined by installing the model parameters of 20-nm FinFET (obtained from open source) on Cadence platform with +0.4 V supply rail at frequencies of 1, 2 and 10 GHz. Simulation results have confirmed that proposed Miller encoder offers a simpler design with reduced transistor count and gives lower power dissipation, higher frequency range of operation at lower supply rail as compared to other candidate designs. Proposed design also promises less propagation delay.
Ultra-narrowband Metamaterial Absorbers for Multispectral Infrared Microsystems

of the Thesis Ultra-narrowband Metamaterial Absorbers for Multispectral Infrared Microsystems by Sungho Kang Master of Science in Electrical and Computer Engineering Northeastern University, December 2018 Dr. Matteo Rinaldi, Advisor IR absorption spectroscopy is a powerful technique to identify and study chemicals or objects of various kinds in a non-disruptive way. Recently, the demand for high performance and compact IR spectroscopy systems has been steadily growing due to the advent of Internet of Things and the burgeoning development of miniaturized sensors. The key challenge lies in realizing multispectral absorber arrays that are lithographically defined and integrated on the same chip, with a minimized footprint. This challenge has been tackled in the study of metamaterials absorbers, the artificial materials composed of an array of subwavelength structures that manipulate electromagnetic waves to achieve extraordinary light absorption properties. The MIM IR absorbers, in particular, are characterized by the near-unity absorptance with lithographically tunable peak absorption wavelength and spectral selectivity in an ultra-thin form factor, suitable for the implementation of miniaturized spectroscopic IR microsystems. Nevertheless, there has been no accurate analytical model to guide the design of MIM IR absorbers with ultra-narrow absorption bandwidth and near-unity absorption, while meeting all the stringent requirements for high-resolution multispectral IR microsystems. This thesis presents the modeling and characterization of ultra-narrowband MIM IR absorbers based on the modified circuit model capable of accurately predicting the spectral responses of MIM IR absorbers. The simultaneous excitation of electric and magnetic resonances in the MIM IR absorbers is modeled via the addition of coupling capacitance to the existing RLC circuit branch, resulting in the accurate description of the effective surface impedance. The model is experimentally validated in the mid-wavelength IR spectral range (λ = 3 ∼ 7μm) and exploited for the first demonstration of a narrowband MIM IR absorber that exhibits performance approaching the predicted physical limits: full-width at half-maximum ≈3 % and near-unity absorption (η > 99.7%) at 5.83 μm wavelength, while independent of incident angle and polarization of the impinging IR
Effect of Dietary L-Ascorby1-2-phosphate Magnesium on Gonadal Maturation of Penaeus japonicus

Studies into the role of ascorbic acid (AsA) in penaeid nutrition have focused on its effects in immature stages, with respect to nutritional status, requirements, deficiency disease, body defense mechanism, wound repair, and collagen forma tion.1-8) A possible role of AsA in reproduction has been reported in shrimps and fish. Palaemon ser ratus,9) Carassius carassius,10) and Gadus morhua11) females were observed to accumulate AsA during ovarian maturation. Fish testes, however, con tained lower AsA concentrations as compared to the ovaries.10-13) High concentrations of AsA in fish roes have also been observed.12,14-16) In captive salmonid broodstock, feed should be for tified with AsA to give at least 100mg/kg dry diet at the time of feeding.17 AsA may have a critical function in fish reproduction, and feeding AsA deficient diet to broodstock could impair repro ductive performance.18) AsA functions not only as an anti-oxidant and as an enzyme co-factor in the formation of collagen,19) it is also involved in the regulation of biosynthesis of sex steroids. 12,20) In the present study, a relatively stable derivative of AsA, L-ascorbyl-2-phosphate magnesium (APM) was used. APM was shown to be stable during processing and storage, with low leachability in seawater compared to AsA.8) Its metabolism in P. japonicus remains unknown; however, it has been shown to be utilized by juveniles as a suit able replacement for AsA. A supplement of 215430mg APM per kg diet was sufficient to prevent clinical signs of AsA deficiency,8) and 215mg/kg AsA activity from APM promoted normal growth in P. japonicus juveniles. *2 The present study therefore aimed to investigate the effects of APM levels on the growth, survival, hepatosomatic index, and gonadosomatic index of female and male P. japonicus broodstock. The effect of APM diets on AsA concentrations in tissues and hemolymph was also determined.
Selection of an Optimal Network-Ranking Model to Achieve the Optimal Production Line Value Chain: a Case Study in the Textile Industry

Fulfilling needs and organisational resources with the least cost and highest quality is the main reason to achieve the optimal value chain. Application of most of the current techniques has merely been intended to choose the best scenario. However, industrial units need to build an ideal scenario as a value chain which focuses on intangible interstitial and hidden factors: good (good nature), bad (bad nature), fixed (obligatory nature) and free (not identifying their nature) and creates value. Therefore the model presented in this article answers this issue. First of all, we present a model based on the network approach of data envelopment analysis, then assess and rank the stages based on the scenarios for the stages forming the value chain, and finally the ideal decision unit is presented. For this reason, the general efficiency is designed with two natures; 1. input-centered (concentration on the costs) and 2. output-centered (concentration on the incomes).
Who could be behind QAnon? Authorship attribution with supervised machine-learning

A series of social media posts on 4chan then 8chan, signed under the pseudonym ‘Q’, started a movement known as QAnon, which led some of its most radical supporters to violent and illegal actions. To identify the person(s) behind Q, we evaluate the coincidence between the linguistic properties of the texts written by Q and to those written by a list of suspects provided by journalistic investigation. To identify the authors of these posts, serious challenges have to be addressed. The ‘Q drops’ are very short texts, written in a way that constitute a sort of literary genre in itself, with very peculiar features of style. These texts might have been written by different authors, whose other writings are often hard to find. After an online ethnography of the movement, necessary to collect enough material written by these thirteen potential authors, we use supervised machine learning to build stylistic profiles for each of them. We then performed a ‘rolling analysis’, looking repeatedly through a moving window for parts of Q’s writings matching our profiles. We conclude that two different individuals, Paul F. and Ron W. , are the closest match to Q’s linguistic signature, and they could have successively written Q’s texts. These potential authors are not high-ranked personality from the US administration, but rather social media activists.
NONPARAMETRIC BAYESIAN MULTIPLE HYPOTHESIS TESTING OF AUTOREGRESSIVE TIME SERIES

This paper describes a framework for flexible multiple hypothesis testing of autoregressive time series. The modeling approach is Bayesian, thought a blend of frequentist and Bayesian reasoning is used to evaluate procedures. Nonparametric characterizations of both the null and alternative hypotheses will be shown to be the key robustification step necessary to ensure reasonable Type-I error performance. The methodology is applied to part of a large database containing up to 50 years of corporate performance statistics on 24,157 publicly traded American companies, where the primary goal of the analysis is to flag companies whose historical performance is significantly different from that expected due to chance.
Modeling bilingual word associations as connected monolingual networks

Word associations are a common tool in research on the mental lexicon. Studies re-port that bilinguals produce different word associations in their non-native language than monolinguals, and propose at least three mechanisms responsible for this difference: bilinguals may rely on their native associations (through translation), on collocational patterns, and on the phonological similarity between words. In this paper, we ﬁrst test the differences between monolingual and bilingual responses, showing that these differences are consistent and signiﬁcant. Second, we present a computational model of bilingual word associations, im-plemented as a semantic network paired with a retrieval mechanism. Our model predicts bilingual word associations better than monolingual baselines, and translation is the main mechanism explaining its suc-cess, while collocational and phonological associations do not improve the model.
A COMPARISON OF THREE PUBLIC PROJECTS THAT INCLUDED COMMUNITY PARTICIPATION TO DETERMINE THE TOTAL VALUE ADD

170 ABSTRACT Some of the most pressing and challenging problems facing South Africa are unemployment, poverty, urban redress, infrastructural decay, under- education, and the transformation of the landscape left by apartheid. In an effort to address these problems, the successive democratic governments embarked on a number of initiatives that were aimed at providing relief through building and construction projects, which require the participation by, and employment of local community members. To facilitate the desired redress, various programmes were launched and a number of projects undertaken. Some of these projects were flagship projects that were lauded by the architectural profession and attracted wide publicity. The socio-economic benefits to the community and local area, the extent of skills transfer to the community participants, and the long-term benefits they brought to the community participants are less obvious. This article revisits three such projects as case studies, with the aim of determining the extent to which they helped address the aforementioned problems and the extent of the benefits they brought to their physical and social contexts. This is done through a literature review supported by semi-structured interviews of relevant role players and an observational visit to each, in order to make recommendations suggesting how future projects could be configured to maximise the long-term benefit they could bring to their physical and social environments while addressing the national challenges. It is recommended that infrastructural development programmes such as the Extended Public Works Programme must prioritise the socio-economic upliftment and sustainable empowerment of people and configure projects with this as their main aim. te spreek en die bydrae wat hulle tot die opheffing van hul fisiese en sosiale omgewings gebring het, te ondersoek. Die doelwit is om op grond van ’n literatuurstudie, opgevolg deur semi-gestruktureerde onderhoude met toepaslike rolspelers en visuele observasies tydens besoeke aan die projekte en analise, aanbevelings te maak aangaande die strukturering van toekomstige projekte, ten einde die voordele wat hulle mag inhou te optimaliseer in die stryd teen die genoemde probleme. Daar word aanbeveel dat programme vir infrastrukturele ontwikkeling, soos die ‘Extended Public Works Programme’, in hul keuse en strukturering van projekte die sosio-ekonomiese opheffing van mense en die skep van volhoubare werksgeleenthede moet prioritiseer.
Novel BiVO 4 @C 3 N 4 @GO Composites with Higher Photocatalytic Performance

: BiVO 4 , BiVO 4 @C 3 N 4 and BiVO 4 @C 3 N 4 @GO composite photo-catalysts were synthesized, and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectrometry (EDS), transmission electron microscopy (TEM), ultraviolet-visible diffuse reflectance spectroscopy (UV-vis DRS), Fourier transform infrared spectroscopy (FT-IR), and Brunauer-Emmett-Teller (BET) surface area techniques. The photocatalytic activity was evaluated on the degradation of methylene blue (MB) under visible light irradiation, which denoted that the BiVO 4 @C 3 N 4 @GO ternary composite outperformed the binary composite BiVO 4 @C 3 N 4 and BiVO 4 . Then the effects of catalyst dosage, initial pH value, and initial methylene blue concentration on the degradation process were investigated systematically. The improvement of visible-light photocatalytic degradation performance was attributed to the enhanced visible light absorption, larger surface area, higher adsorption ability, and prolonged lifetime of photo-generated electron-hole pairs. The recycle experiments results showed that the BiVO 4 @C 3 N 4 @GO composite had excellent photo-stability for MB photocatalytic degradation.
and Macrophage Colony Stimulating Factor–mediated Signals on Phospholipase C g in Prefusion Osteoclasts

The macrophage colony stimulating factor (M-CSF) and a v b 3 integrins play critical roles in osteoclast function. This study examines M-CSF– and adhe-sion-induced signaling in prefusion osteoclasts (pOCs) derived from Src-deﬁcient and wild-type mice. Src-deﬁ-cient cells attach to but do not spread on vitronectin (Vn)-coated surfaces and, contrary to wild-type cells, their adhesion does not lead to tyrosine phosphorylation of molecules activated by adhesion, including PYK2, p130 Cas , paxillin, and PLC- g . However, in response to M-CSF, Src 2/2 pOCs spread and migrate on Vn in an a v b 3 -dependent manner. Involvement of PLC- g activation is suggested by using a PLC inhibitor, U73122, which blocks both adhesion- and M-CSF– mediated cell spreading. Furthermore, in Src 2/2 pOCs M-CSF, together with ﬁlamentous actin, causes recruitment of b 3 integrin and PLC- g to adhesion contacts and induces stable association of b 3 integrin with PLC- g , phosphatidylinositol 3-kinase, and PYK2. Moreover, direct interaction of PYK2 and PLC- g can be induced by either adhesion or M-CSF, suggesting that this interaction may enable the formation of integrin-associated complexes. Furthermore, this study suggests that in pOCs PLC- g is a common downstream mediator for adhesion and growth factor signals. M-CSF–initiated signaling modulates the a v b 3 integrin-mediated cytoskeletal reorganization in prefusion osteoclasts in the absence of c-Src, possibly via PLC- g . to adhesion contacts. M-CSF also induced the association of a v b 3 integrin with several signaling molecules including PLC- g , PI 3-kinase, and PYK2 in a Src-independent manner, which was blocked by a PLC inhibitor. The interaction between a v b 3 and these molecules in pOCs seems to depend on the association of PYK2 and PLC- g . These data suggest that PLC- g is an important effector of a v b 3 - and M-CSF–mediated signaling pathways involved in prefusion osteoclast spreading.
JA-responsive AP2/ERF-domain transcription factors have distinct roles in JA signaling in Arabidopsis thaliana

Jasmonic acid (JA) is an important plant hormone involved in defense responses against external threats. JA perception leads to the activation of specific set of defense genes. In Arabidopsis, the expression of several genes, named ORA genes, encoding members of the AP2/ERF-domain transcription factor family, is induced by JA. The role of ORA59, ORA47 and ORA37 in JA signaling was described in the previous chapters. In order to assess the functions of the remaining ORA transcription factors and to address the question of functional redundancy, transgenic plants overexpressing individual ORA genes under the control of an inducible promoter were constructed. Several JA-responsive genes showed high transcript levels in plants overexpressing a specific ORA, indicating that these genes are regulated by a unique AP2/ERF-domain transcription factor within the set tested. In contrast, a number of JA-responsive genes were upregulated in several ORA -overexpressing plants, suggesting functional redundancy among these ORAs.
Fetal Physiological Programming Chronic alterations in ovine maternal corticosteroid levels inﬂuence uterine blood ﬂow and placental and fetal growth

Chronic alterations in ovine maternal corticosteroid levels inﬂuence uterine blood ﬂow and placental and fetal growth. Am J Physiol Regul Integr Physiol work from this laboratory demonstrated that the elevation of maternal plasma corticosteroid concentrations during pregnancy is important for the support of fetal development. Reducing ovine maternal plasma cortisol concentrations to nonpregnant levels stimulates homeostatic responses that defend fetal blood volume. The present study was designed to test the hypothesis that chronic decreases or increases in maternal plasma cortisol concentration alter uterine and placental blood ﬂow and morphology. Three groups of pregnant ewes and their fetuses were chronically catheterized and studied: ewes infused with cortisol (1 mg (cid:1) kg (cid:1) 1 (cid:1) day (cid:1) 1 ; high cortisol), ewes adrenalectomized and underreplaced with cortisol (0.5 mg (cid:1) kg (cid:1) 1 (cid:1) day (cid:1) 1 ; low cortisol), and control ewes. The normal increment in uterine blood ﬂow between 120 and 130 days was eliminated in the low-cortisol ewes; conversely, uterine blood ﬂow was increased in the high-cortisol group compared with the control group. Fetal arterial blood pressure was increased in the high-cortisol group compared with controls, but there was no increase in fetal arterial pressure from 120 to 130 days of gestation in the low-cortisol group. The fetuses of both low-cortisol and high-cortisol groups had altered placental morphology, with increased proportions of type B placentomes, and overall reduced fetal placental blood ﬂow. The rate of fetal somatic growth was impaired in both low-cortisol and high-cortisol groups compared with the fetuses in the intact group. The results of this study demonstrate that maternal plasma cortisol during pregnancy is an important contributor to the maternal environment supporting optimal conditions for fetal homeostasis and somatic growth.
CLINICAL ANALYSIS OF HEPATOCELLULAR CARCINOMA AFTER HEPATIC RESECTION IN YOUNGER VERSUS ELDERLY PATIENTS

: Objectives : Analyze the clinical preoperative laboratory data, intraoperative findings, and surgical outcome of HCC in older v/s younger patients those who underwent surgical resection. Methods : A total of 51 “elderly” (≥65 years old) and 102 “younger” (≤65 years old) who underwent hepatic resection between January 2013 to February 2020 were identified and included in this study. Demographic and operative data, pathological findings, and postoperative outcomes were collected. Prognostic factors were analyzed by univariate and multivariate analysis. Results: In both of groups, younger males (91.17%) and older female (23.6%) with a combined P-value <0.004, have a higher proportion of HCC. More underlying Hepatitis B virus infection and cirrhosis found in younger (84.4% - 94.1%). More underlying diabetes mellitus and Hepatitis C were observed in elderly HCC. There was no significant statistical difference in the Child-Pugh class in both groups. The intraoperative parameters younger patients received right-sided hepatectomy, right hepatectomy (65.7%), and right trisegmentomy (10.8%) while the older patients mostly received left-sided hepatectomy, left hepatectomy (37.3%). Postoperative pneumonia and pleural effusion common in younger group (9.8%,P<0.514 and 34.5%,P<0.312 respectively), while wound infections were most commonly seen in the elderly (19.6%, P<0.530). The overall estimated mortality and hospitalization were not significantly different in both groups. Conclusion : Two groups of operative outcomes indicated that the right lobe of liver HCC more in the younger and left lobe more in older patients and post-operative wound infection in elderly and pleural effusion. Still, it proves that a hepatic resection is a safe option in Hepatocellular carcinoma. All data described as percentages of patients, mean, and standard deviation. The continuous variables are expressed as median (range). T-test and Pearson Chi-square used for continuous variables. Kaplan-Meier method used to calculate disease-free survival rate and log-rank test for comparison of groups. Cox regression model helped to get multivariate analysis. Every analysis, P<0.05 consideration, show statistical significance.
