Compact Dual-Polarized Corrugated Horn Antenna for Satellite Communications

In this article, a structure and design procedure of a novel compact dual-polarized corrugated horn antenna with high gain and a stable phase center for satellite communication is presented. The antenna incorporates an ortho-mode transducer (OMT), a mode converter, and a corrugated structure. The compact OMT section is designed to be fed by standard WR-75 waveguides. The proposed compact design utilizes only ten corrugated slots to yield a symmetric radiation pattern. The antenna impedance bandwidth (VSWR < 1.5) is 10.2 to 15 GHz. Furthermore, the antenna exhibits 14–17 dBi gain, a constant 30° half-power beamwidth (HPBW) radiation pattern, and less than 9 mm phase center variation over the operating frequency range. The aperture diameter is 7 cm and the total antenna length is 15 cm. Due to the aforementioned features, the proposed antenna is suitable as the feed reflector for both uplink and downlink satellite communications. The design is numerically and experimentally validated.
The African economic growth experience and tourism receipts: A threshold analysis and quantile regression approach

By applying threshold analysis and quantile regression techniques, we investigate the linearity of the relationship between tourism receipts and economic growth. We find that a threshold exists, below and above which the relationship between tourism receipts and economic growth changes. In our sample, the threshold for tourism receipts is at 3.82% of gross domestic product. Specifically, our findings suggest that tourism receipts have a more pronounced effect on economic growth below the threshold than above the threshold. From the quantile regression analysis, we further find that countries have greater benefits from tourism at lower levels of economic growth. Thus, policy makers designing tourism policy may consider that the marginal benefit of tourism on growth wanes beyond certain levels in spite of the fact that tourism receipts are an important driver of economic growth at all levels of growth.
Impacts of Dietary L-Threonine Supplementation on Performance and Intestinal Morphology of Broiler Chickens during Summer Time

The present study evaluated effects of 0.0%, 0.5%, 0.75% and 1.0% L-threonine in diet on performance and gastrointestinal tract development in broiler chickens during summer. From 0 to 42 days old, body weight gain was greater in 0.75% L-threonine fed birds than in 0.0% and 0.5% L-threonine fed birds (P 0.05). No significant differences were observed between the treatments for feed intake and feed conversion ratio during the starter, grower or whole experimental period (P>0.05). During the growth period, 0.75% L-threonine fed birds had the highest body weight gain (P 0.05). In conclusion, supplementation of 0.75% L-threonine improved the intestinal morphology and body weight gain of broilers under hot conditions. As well as, the higher levels of L-threonine (1.0) percent in diet can will increased the villus height in the jejunum and ileum.
A Novel Extended Higher-Order Moment Multi-Factor Framework for Forecasting the Carbon Price: Testing on the Multilayer Long Short-Term Memory Network

Predicting the carbon price accurately can not only promote the sustainability of the carbon market and the price driving mechanism of carbon emissions, but can also help investors avoid market risks and increase returns. However, previous research has only focused on the low-order moment perspective of the returns for predicting the carbon price, while ignoring the shock of extreme events and market asymmetry originating from its pricing factor markets. In this paper, a novel extended higher-order moment multi-factor framework (EHM-APT) was formed to improve the prediction and to capture the driving mechanism of the carbon price. Furthermore, a multi-layer and multi-variable Long Short-Term Memory Network (Multi-LSTM) model was constructed so that the parameters and structure could be determined experimentally for testing the performance of the proposed framework. The results show that the pricing framework considers the shock of extreme events and market asymmetry and can improve the prediction compared with a framework that does not consider the shock of higher-order moment terms. Additionally, the Multi-LSTM model is more competitive for prediction than other benchmark models. This conclusion proves the rationality and accuracy of the proposed framework. The application of the pricing framework encourages investors and financial institutions to pay more attention to the pricing factor of extreme events and market asymmetry for accurate price prediction and investment analysis.

Sidoarjo Film Festival 2019 as an Effort to Generate the Indonesian Film Industry

At present, various national film titles have begun to dominate in all regions of Indonesia. Beginning around 2018, the number of film viewers in the country reached 50 million people, an extraordinary achievement, with only 42 million in the previous year. Increasing the number of film viewers in Indonesia certainly can not be separated from the hard work of creative producers in the field of film that continues to produce real work with a variety of interesting, creative content, and of course, contains elements of humanism and culture of the homeland that are still in great demand today. Indonesia, which has a rich cultural and regional potential, has a great opportunity to continue to develop the film industry by raising a variety of content that is culturally charged, and historical value with a little added element of romance in the storyline. However, at the time of the growing popularity of national films, the domestic film industry in several regions in Indonesia still faces many very complex problems, including the Sidoarjo Regency in East Java. Various attempts were made by the government of the Sidoarjo Regency to revive the film industry in its area, one of which was the holding of the 2019 Sidoarjo Film Festival (SFF) in collaboration with Sidoarjo Creative (Sirive). This study aims to determine the efforts of the Sidoarjo Regency Government in reviving the film industry through SSF 2019 as one of the new business opportunities for young creators in the Sidoarjo region, through a qualitative approach with interview methods to the Government Public Relations of Sidoarjo and Sirive (key informant) as the organizer of SFF 2019, and young Sidoarjo creators (informants) as SFF 2019 participants. The results of the study found that SFF 2019 was much sought after by young creators in honing and developing talent in producing indie or short movies so that they were expected to be able to become new business opportunities in creative content in the Sidoarjo regency through activities similar in a variety of event formats, in the form of focus group discussion, workshops, seminars, film festivals, and screening day.
A NOVEL NON-CANONICAL WNT PATHWAY REGULATES THE ASYMMETRIC B CELL DIVISION IN CAENORHABDITIS ELEGANS

The polarities of several cells that divide asymmetrically during C. elegans development are controlled by Wnt signaling. LIN-44/Wnt and LIN-17/Fz control the polarities of cells in the tail of developing C. elegans larvae, including the male-specific blast cell, B, which divides asymmetrically to generate a larger anterior daughter and a smaller posterior daughter. We determined that the canonical Wnt pathway components are not involved in the control of B cell polarity. However, POP-1/Tcf is involved and asymmetrically distributed to B daughter nuclei. Aspects of the B cell division are reminiscent of the divisions controlled by the planar cell polarity (PCP) pathway that has been described in both Drosophila and vertebrate systems. We identified C. elegans homologs of Wnt/PCP components and have determined that many of them appear to be involved in the regulation of B cell polarity and POP-1 asymmetric distribution to B daughter nuclei. Thus a non-canonical Wnt pathway, which is different from other Wnt pathways in C. elegans, but similar to the PCP pathways, appears to regulate B cell polarity. Molecular mechanisms of this PCP pathway were also investigated. We determined that LIN17/Fz is asymmetrically distributed to the B cell cortex prior to, during, and after, division. Furthermore, the asymmetric localization of LIN-17::GFP is controlled by LIN-44/Wnt and MIG-5/Dsh. The cysteine rich domain (CRD), seven trans-membrane domain and KTXXXW motif of LIN-17 are required for LIN-17 to rescue lin-17, while only seven trans-membrane domains and KTXXXW motif are required for LIN-17 asymmetric localization. MIG-5::GFP asymmetrically localized to the B cell prior to and after division in a LIN-17/Fz dependent manner. We examined the functions of these MIG-5 domains. The DEP domain is required for MIG-5 membrane association, while the PDZ domain is responsible for different levels of MIG5 in the B daughters. The DEP and PDZ domain are required to rescue B cell polarity defect of mig-5 males, while the DIX domain is not that important. In summary, a novel PCP-like pathway, in which LIN-17 and MIG-5 are asymmetrically localized, is conserved in C. elegans and involved in the regulation of B cell polarity.

Evolution of the brain : neuroanatomy, development, and paleontology

The human species is the only species that has ever created a symphony, written a poem, developed a mathematical equation, or studied its own origins. The biological structure that has enabled humans to perform these feats of intelligence is the human brain. This module by Daniel D. White explores the basics of neuroanatomy, brain development, lateralization, sexual dimorphism, and the fossil evidence for hominin brain evolution.
Prospects of Electric Vehicles in the Developing Countries: A Literature Review

Electric mobility offers a low cost of travel along with energy and harmful emissions savings. Nevertheless, a comprehensive literature review is missing for the prospects of electric vehicles in developing countries. Such an overview would be instrumental for policymakers to understand the barriers and opportunities related to different types of electric vehicles (EVs). Considering the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines, a systematic review was performed of the electronic databases Google Scholar and Web of Science for the years 2010–2020. The electric four-wheelers, hybrid electric vehicles and electric two-wheeler constituted the electric vehicles searched in the databases. Initially, 35 studies identified in the Web of Science that matched the criteria were studied. Later, 105 other relevant reports and articles related to barriers and opportunities were found by using Google Scholar and studied. Results reveal that electric four-wheelers are not a feasible option in developing countries due to their high purchase price. On the contrary, electric two-wheelers may be beneficial as they come with a lower purchase price.
Relationship Between Intestinal Microbiota and Clinical Characteristics of Patients with Early Stage Breast Cancer

Gut microbiota is involved in numerous physiopathological situations including cancers. Our objective is to evaluate the relationship between the composition of microbiota and the clinicobiological characteristics of patients with breast cancer. Clinical data and faeces from 32 patients with early stage breast cancer were collected, before any therapeutic intervention. Bacterial DNA extracted from faeces was amplified by PCR targeting 16S rRNA gene sequences specific to different bacterial phyla. Expression was compared in groups of patients defined by clinical stages of the disease as well as BMI. Most patients suffered of invasive ductal (81%), clinical stage 0 (46.9%), with histological grading II (62.5 %), ER/PgR (80%) and HER2 (15%). About 28.1 % and 12.5 % of patients were overweight and/or obese, respectively. Significant differences were observed for absolute numbers of total bacteria and for some studied bacterial groups (F prausnitzii, Firmicutes, Blautia and Egerthella) according to BMI. Compared with patients with grade I (n=5), patients with grade III (n=7) had increased absolute numbers of Blautia sp. (9.8±0.2 vs 9.5 ± 0.2 log copies.g‐1, p=0.048), for example. Furthermore, absolute numbers of Bifidobacterium and Blautia, and proportions of F Prausnitzii and Blautia, were significanly different according to clinical stages. Our study highlighted that, in these patients, intestinal microbiota composition differs according to clinical characteristics and BMI. These results should be confirmed to clarify the link between breast cancer and intestinal microbiota.
Public Beliefs about Falsehoods in News

The circulation of misinformation, lies, propaganda, and other kinds of falsehood has, to varying degrees, become a challenge to democratic publics. We are interested in the question of what publics believe about their own exposure to falsehoods in news, and about what contributes to similarities and differences in these beliefs across countries. We are also interested in the question of whether publics report attempting to verify news that is suspect to them. Here we report on a comparative election survey in the United States, the United Kingdom, and France. We find three key predictors of publics’ beliefs that they have been exposed to falsehoods: discussion of news, use of social media for political purposes, and exposure to counter-attitudinal information. The nexus between these three predictors and beliefs about falsehoods exists in all three countries, as we anticipate that it likely exists elsewhere. We do not find voters on the right to be different from those on the left in the United Kingdom and France, but do find a substantial difference in the United States, which is likely due to the 2016 Trump campaign. We conclude with concerns about the imbalance in beliefs about exposure to falsehoods in the United States and the apparent capacity of a single leader, in the right context, to shape public beliefs about what is to be believed.
Influence the addition of Fe2+ and H2O2 on removal and decolorization of textile dye (dispersive yellow 42 dye)

This research compares the addition of some oxidant agents such as Fe2+, H2O2 and mixture from both to aqueous solution of dispersive yellow 42 dye, which regarded as an organic contaminant. This work performed during the dark reaction and photo reaction under artificial UV-A light (HPML -125 watt). In reality, the addition of the oxidant agents leaded to raise the light resistance of this dye to decolorize, this results can be used to increase the life time for textile materials which painted by this dye. The removal percentage without addition oxidant agent at 20 oC was decreased from 32.710 % to 21.445, 11.439 and 8.785% for addition Fe2+, H2O2 and mixing of both respectively. Moreover, the decolorization percentage for mention materials was depressed from 94.444 to 60.869, 4.163 and 16.044 respectively. The effect of temperature determined with chose Fe2+ as oxidant agent and compared with reaction without any addition, because the change is less compared with the other studied cases. The kinetic study of the photo-decolorization process of this dye demonstrated that the generated response is pseudo-first order. The Fenton and photo-Fenton improve the resistance of dye to decolorize during illuminated by light.The dye removal rates depress with the temperature increases from 288 K to 303 K; that due to the dark reaction is exothermic, nonspontaneous and obeys the physical adsorption depending on the values of enthalpy and free energy. In the contrast, the responsed of photodecolorization for this dye is found to be endothermic m non spontaneous and less random.
Handle-Hand Compatibility Effects for the Right and Left Hand Using Reach-to-Touch Movements

In stimulus-response compatibility tasks, performance is better when the handle of an object is oriented on the same side of the response than when the handle is oriented on the opposite side. Two major alternative accounts, the motor affordance and spatial accounts, have been proposed to explain this handle-hand compatibility effect. In two experiments, we tested between these two accounts by administering a go/no-go task to right-handed participants. Handled objects presented on a touchscreen were used as stimuli. Half of the participants had to reach-to-touch the stimuli by using their dominant hand, the other half by using their nondominant hand. Liftoff times (LTs), movement times (MTs) and spatial coordinates of the movement endpoints were recorded. Results from the LTs and MTs analyses showed no evidence of handle-hand compatibility effects. In contrast, the analyses of the spatial coordinates revealed that participants' touches were shifted more laterally towards the handle when the handles were oriented on the same side of the responding hand (Experiments 1 and 2). Furthermore, the right-hand touches landed higher (towards the handle) than the left-hand touches, especially when the vertical object dimension was particularly salient (Experiment 1). Overall, these results are in line with the activation of hand motor programs to reach and grasp the object as predicted by the motor account, at least for the right/dominant hand.

Nonlinear unmanned aerial vehicle formation control via composite Laplacian quadratics

This article studies a leader‐following formation control problem, in which the agent model is governed by continuous‐time nonlinear differential equations. We are interested in designing a distributed control algorithm which is capable of handling the strong nonlinearities induced by the unmanned aerial vehicle model. Our primary objective is to investigate the convergence of the corresponding closed‐loop system, and to understand how the nonlinear dynamics and the network topologies may impose intrinsic barriers on formation control. The results show that an exponential convergence is guaranteed under the proposed algorithm via the composite Laplacian quadratics function as long as the network topology has a directed spanning tree.
A Ordem Zingiberales nos Herbários do Estado de Pernambuco.

Zingiberales é uma ordem de monocotiledôneas constituída por oito famílias: Cannaceae, Costaceae, Heliconiaceae, Lowiaceae, Marantaceae, Musaceae, Strelitziaceae e Zingiberaceae [1], formada por ervas perenes de distribuição pantropical, cujas famílias, com exceção de Lowiaceae e Musaceae, possuem representantes nativos do Brasil [2]. Entre seus representantes, encontram-se espécies de interesse comercial, tanto para a alimentação humana, como Musa paradisiaca L. (Musaceae), Maranta arundinacea L. e Calathea allouia Lindl. , (Marantaceae) [3], quanto para uso artesanal, como Ischnosiphon gracilis Koern. (Marantaceae) [4] e ainda medicinal e condimentar, a exemplo de Zingiber officinale Rosc. , Alpinia zerumbet (Pers.) B.L. Burtt & R.M. Sm. e Hedychium coronarium J.Koenig (Zingiberaceae) [5]. A ordem Zingiberales também possui grande importância ecológica, pois Marantaceae apresenta destaque como recurso floral a abelhas Euglossini, esfingídeos e beija-flores [4, 6], Heliconiaceae fornecem recursos essenciais para espécies de beija-flores como Glaucis hirsuta (Phaethornithinae), Phaethornis pretrei, Amazilia fimbriata e Eupetomena macroura (Trochilinae) [7], Costaceae para diversas aves [8] e, segundo Endrees [9], “Zingiberaceae é considerada a maior família de monocotiledôneas polinizadas por vertebrados”. Levando-se em consideração que o conhecimento do número e distribuição das espécies de um determinado grupo biológico é a premissa para quaisquer estudos [10], que algumas famílias de Zingiberales são pouco estudadas na América do Sul [7; 11] ao mesmo tempo em que altos níveis de riqueza e endemismos são registrados para o grupo em hábitats ameaçados [4; 12; 13], como a Floresta Atlântica [4], o que sugere que algumas espécies da ordem provavelmente estão ameaçadas de extinção, estudos como este se fazem urgentes. Este trabalho tem por objetivos responder as seguintes questões a respeito da Ordem Zingiberales nos herbários do estado de Pernambuco: (1) Quantas famílias e espécies estão depositadas nos herbários pernambucanos? (2) Quantas famílias e espécies são nativas do Estado? (3) Existem espécies raras e endêmicas? (4) e de ampla distribuição e exóticas? Material e métodos
