Chicken Swarm Optimization for PTS based PAPR Reduction in OFDM Systems
Authors: Gupta Saruti , Goel Ashish
Published: July 2020

Partial transmit sequence (PTS) is a well-known PAPR reduction scheme for the OFDM system. One of the major challenge of this scheme is to find an optimal phase vector using exhaustive search over all the allowed phase factor combinations. This leads to increased search complexity which grows exponentially as the number of sub-blocks is increased. In this paper, chicken swarm optimization (CSO) based PTS system is designed that aims to find an optimal solution in less number of average iterations and therefore results in reduced computational complexity of the system. We have proposed two categories of the algorithm: (i) CSO-PTS system without threshold limit on PAPR (ii) CSO-PTS system with threshold limit on PAPR. Both the schemes offer effective trade-offs between the computationalcomplexity and the PAPR reduction capability of the system. Simulation results confirm that our proposed schemes perform well in terms of low computational complexity, lesser number of average iterations and improved PAPR reduction capability of the OFDM signal without any loss in BER performance of the system.

Published: July 2020

Abstract. The Ganesha statue without a crown is one of the unique depictions of archeological remains in Indonesia. These statues can be found in several areas such as Temanggung, Pekalongan, the National Museum, and Yogyakarta. This uniqueness is a reason to be appointed in an initial assessment. This is because no one has ever discussed this topic. Therefore, the challenge to be raised on this occasion is about the Ganesha in the community regarding their portrayal in the form without a crown? The objective to be achieved from this discussion is a discussion of Javanese society related to the previous discussion. In answering these questions, qualitative research methods are used by taking secondary data from a literature review. The approach used in this review discusses the iconology proposed to explain the background of phenomena that occur through related stories or mythologies. Through an analysis of the results, offering three initial responses to the crownless Ganesha statue, related to the story of Ganesh who prevented Ravana from bringing Atmalinga to Lanka, the spread of Gupta art in Southeast Asia, and related to traditions outside the palace.

Published: July 2020

Professionals use language in particular ways, which are usually very accurate and precise, to communicate among themselves. Yet, some professionals, such as those in the olive oil tasting industry, face the problem of describing subjective impressions expressed and interpreted through language. The aim of this paper is the description of the genre and the language of olive oil tasting notes in English, focusing on the ways lexical units combine in order to help those olive oil tasting professionals produce acceptable olive oil tasting notes in English for their discourse community. This has been done using a corpus of olive oil tasting notes originally written in English designed and compiled ad-hoc for this purpose. Word combinations have been analysed from two perspectives: syntactic and grammatical form and function, and lexical semantics. The conclusions of these analyses and their results are intended to be a model upon which olive oil tasting language users can rely to write olive oil tasting notes with an accepted linguistic quality, allowing them to be recognized as part of the genre by the discourse community.

Economics of Chickpea Cultivation and Livelihood of Chickpea farmers in Drought-prone Region of Bangladesh
Authors: Sharna Shaima Chowdhury
Published: July 2020

The cultivation of improved chickpea varieties has been increasing over time that kicks off the local varieties from the farmerâ€™s field. In this study, we analyze the difference between the profitability of modern and traditional chickpea varieties as well as assess the livelihood of improved and local chickpea farmers in the high barind region of Bangladesh. The values of benefit-cost ratio depict that the improved variety in more profitable in comparison to local chickpea variety. Meanwhile, the multidimensional livelihood index of the Department for International Development reflects that the modern variety cultivars belong in a better livelihood condition than the local variety growers. Among all the five capitals of the multidimensional livelihood index, the difference between these two groups is the largest in the case of social capital, which is followed by financial capital. In the same way, the former group has higher values for human, physical, and natural capital than their counterparts.
Electron-Based Dissociation Is Needed for O-Glycopeptides Derived from OpeRATOR Proteolysis
Authors: Riley Nicholas , Malaker Stacy , Bertozzi Carolyn
Published: July 2020

The recently described O-glycoprotease OpeRATOR presents exciting opportunities for O-glycoproteomics. This bacterial enzyme purified from Akkermansia (Sp). muciniphila cleaves N-terminally to serine and threonine residues that are modified with (preferably asialylated) O-glycans. This provides orthogonal cleavage relative to canonical proteases (e.g., trypsin) for improved O-glycopeptide characterization with tandem mass spectrometry (MS/MS). O-glycopeptides with a modified N-terminal residue, such as those generated by OpeRATOR, present several potential benefits, perhaps the most notable being de facto O-glycosite localization without the need of glycan-retaining fragments in MS/MS spectra. Indeed, O-glycopeptides modified exclusively at the N-terminus would enable O-glycoproteomic methods to rely solely on collision-based fragmentation rather than electron-driven dissociation because glycan-retaining peptide fragments would not be required for localization. The caveat is that modified peptides would need to reliably contain only a single O-glycosite. Here we use methods that combine collision- and electron-based fragmentation to characterize the number of O-glycosites that are present in O-glycopeptides derived from OpeRATOR digestion of four known O-glycoproteins. Our data show that over 50% of O-glycopeptides generated from combined digestion using OpeRATOR and trypsin contain multiple O-glycosites, indicating that collision-based fragmentation alone is not sufficient. Electron-based dissociation methods are necessary to capture the O-glycopeptide diversity present in OpeRATOR digestions.

Effect of Curvature and Placement of Donor and Acceptor Units in Cycloparaphenylenes: A Computational Study
Authors: Lovell Terri , Fosnacht Kaylin , Colwell Curtis , Jasti Ramesh
Published: July 2020

Cycloparaphenylenes have promise as novel fluorescent materials. However, shifting their fluorescence beyond 510 nm is difficult. Herein, we computationally explore the effect on CPP photophysical properties of incorporating electron accepting and electron donating units at the CAM-B3LYP/6-311G** level. We demonstrate that incorporation of donor and acceptor units may shift the CPP fluorescence as far as 1193 nm. This computational work directs the synthesis of bright red-emitting CPPs. Furthermore, the nanohoop architecture allows for interrogation of strain effects on common conjugated polymer donor and acceptor units. Strain results in a bathochromic shift versus linear variants, demonstrating the value of using strain to push the limits of low band gap materials.

Published: July 2020

Post-Partum Hemorrhage (PPH) is defined as the loss of blood which is greater than 500ml after vaginal delivery or greater than 1000 ml after a cesarean section delivery. About 28% of the total maternal deaths were due to PPH particularly in developing countries. Oxytocin has been considered as the ‘gold standard’ drug in the treatment and prevention of PPH. Prophylactic use of prostaglandin analogue i.e., misoprostol in addition to oxytocin during cesarean section is expected to reduce the incidence of PPH. This study aims at comparing the efficacy of combined use of rectal misoprostol and oxytocin infusion with oxytocin in the prevention of PPH. A comparative observational study was conducted on 200 subjects which were divided into two equal groups by Simple Random Selection. One group was treated with Inj. Oxytocin 20U I.V infusion alone while the other group was treated with Tab. Misoprostol 600mcg, rectal route and Inj. Oxytocin 20U I.V infusion. Majority of the subjects were observed under the age group of 21-25years, under primigravidae. A significant decrease in the volume of mean blood loss (740.00 ± 164.00 ml: p = 0.045) and the mean drop of hemoglobin level(Hb) (0.88±0.74gm/dl; p = 0.0001) were observed in group treated with Tab. Misoprostol 600mcg and Inj. Oxytocin and was found to be statistically significant. Preoperative administration of misoprostol per rectal route and oxytocin infusion after the cesarean section have shown, a better control of bleeding and maintenance of hemoglobin level when compared to oxytocin infusion alone. Thus, instead of oxytocin monotherapy combined use of misoprostol and oxytocin would be more effective in prevention of PPH.

Published: July 2020

In this work, a model for the dynamical four-point bending test is present, with particular emphasis on application to an asphalt concrete (AC) composite, a viscoelastic material, based on the Euler-Bernoulli theory, which approaches an equation where the Young modulus E can be substituted by the operator (E + γ∂/∂t), where γ is an internal damping parameter associated to the binder viscoelasticity and t is the time. As course aggregate in the composition of the AC mixture, the sintered aggregate of calcined clay was used, interesting to be employed as an alternative to the lack of natural course aggregate in some regions of the planet, where the presence of sedimentary rocks prevails. The results indicated that γ decreases with the temperature and loading frequency and the apparent noise in the stiffness versus strain curve is resulted from the natural vibration mode of the beam.

Tribolium castaneum is a species of beetle in the family tenebrionidae, the darkling beetle. Conventional insecticides used for controling stored product pests are expensive and arguably associated with various severe adverse side effects hence the need to develop botanical pesticides that are effective as alternative. Though Azadrachta indica has been used for the control of so many insects, review of the literature show no scientifically investigated report of its effectiveness against T. castaneum. This study was therefore designed to evaluate bioinsecticidal activity of ethanolic leaves extract of Azadirachta indica against stored Tribolium castaneum. Different concentrations (60, 70, 80, 90, and 100%) of ethanolic leaves extract of A. indica was applied on the filter paper and were allowed to dry for a reasonable time period. Control was maintained by treating the filter paper with water only. For examining the percent mortality, 15 adults was taken in the Petri dishes embedded with Whitman’s filter paper, covered with lid and tightened with scotch tape on both sides. The A. indica extracts at different concentrations tested showed insecticidal activity against T. castaneum. Further, phytochemical screening results showed that the A. indica extract have phytochemicals associated with insecticidal activity. The study has established that the ethanoloc extract A. indica is effective in managing stored product pest.

Abstract: Every science teacher is expected to always learn throughout life, including learning how to teach students science better and more interesting, so that students like learning science and are eager to learn it with pleasure as such a provision of life. One of the efforts to deal with it is by implementing CTL-based science learning innovation. Learning innovation is the implementation of a new idea at the micro level in classroom in order to improve the learning process and outcomes. This new idea could be implemented by both adopting and adapting what is already emerging or creating a new way of teaching students. Teachers change their role. They no longer teach, but also facilitate their students in experiencing the learning process. The teachers act as models by modeling how to enthusiastically deal with the lifelong learning, creating conducive conditions so that students could experience the so-called active, creative, effective, and fun (PAKEM) learning. Teachers are also expected to develop the character of their students. There are various learning innovations that could be used by teachers, one of which is  primarily based on CTL, which has such characteristics as modeling, constructivism, questioning, developing interpersonal skills, shaping learning communities, reflections, and authentic assessment.Keywords: Science learning, contextual teaching and learning

Whereas lPA is one of the lessons that must involve students directly with the implementation of practicums to improve students' skills. In the process of learning science at SDN Tlogoagung, researchers found that learning outcomes were still low, the average score was 60% lower than the specified KKM, which was 75. This was possible because of the conventional learning process. The focus of the research that will be discussed in this study is about how the effectiveness of the inquiry learning method for learning outcomes and the skills of the science learning process in the matter of energy and its changes. The purpose of this study was to determine the effectiveness of the method of inquiry learning on learning outcomes and the skills of the science learning process on energy matter and its changes. The method used in this study is an experimental method using nonequivalent control group design. Data collection techniques used were interviews, tests, observation sheets and documentation. While the data analysis used is the validity test, reliability test, normality test, homogeneity test, assessment of the test, mean, achievement of learning outcomes, N-Gain, observation of basic process skills, and hypothesis testing using Independent samples t-test. From the results of the study it is known that the use of inquiry learning methods seen from the results of learning between the experimental class with the control class, while the average value of the experimental class post test is 87 while the average value of the control class post test is 79. Based on the results of hypothesis testing indicates that the value sig (2 tailed) smaller than 0.05 so Ho is rejected and Ha is accepted. This means that the inquiry learning method is effective on learning outcomes and the skills of the science learning process on energy matter and its changes.
