Published: June 2020

The revelation of adult brain exhibiting neurogenesis has established that the brain possesses great plasticity and that neurons could be spawned in the neurogenic zones where hippocampal adult neurogenesis attributes to learning and memory processes. With strong implications in brain functional homeostasis, aging and cognition, various aspects of adult neurogenesis reveal exuberant mechanistic associations thereby further aiding in facilitating the therapeutic approaches regarding the development of neurodegenerative processes in Alzheimer’s Disease (AD). Impaired neurogenesis has been significantly evident in AD with compromised hippocampal function and cognitive deficits. Melatonin the pineal indolamine augments neurogenesis and has been linked to AD development as its levels are compromised with disease progression. Here, in this review, we discuss and appraise the mechanisms via which melatonin regulates neurogenesis in pathophysiological conditions which would unravel the molecular basis in such conditions and its role in endogenous brain repair. Also, its components as key regulators of neural stem and progenitor cell proliferation and differentiation in the embryonic and adult brain would aid in accentuating the therapeutic implications of this indoleamine in line of prevention and treatment of AD.
Biorhythmic and receptor mediated interplay between melatonin and insulin: its consequences on diabetic erythrocytes
Authors: Banerjee Adrita , Chattopadhyay Aindrila , Bandyopadhyay Debasish
Published: June 2020

Diabetes mellitus, one of the crucial epidemics of this country has snatched the sleep of mankind with a steep slope of 108 million in 1980 to more than 460 million in today’s world. The global statistics based on numerological information from World Health Organization (WHO) proposed alarmingly about 642 million affected individuals by 2040. Type 1 diabetes is due to damaged pancreatic β-cells while type 2 diabetes is a result of insulin insensitivity associated with hyperglycaemia. Hyperglycaemia is a principal symptom of diabetes. As a result, the circulatory erythrocytes [red blood cells (RBCs)] become the first and most vulnerable victims to confront such a stressful environment. The RBCs possess many components including haemoglobin, membrane proteins and lipids. They prefer to interact with glucose and form glycated haemoglobin and membrane phospholipid asymmetry which alters RBC adherence. These alterations trigger intracellular reactive oxygen species (ROS) formation and oxidative damage in diabetic erythrocytes. Melatonin, an indoleamine, ameliorates oxidative stress in various tissues and has the capacity of shielding erythrocytes from deleterious stress. A crucial relationship between melatonin and insulin indicates their interplay in occurrence of diabetes. Biorhythm entrained and receptor mediated action of melatonin on pancreatic β-cells in the context of hyperglycaemia are discussed for the first time in the review. Since melatonin protects against erythrocytes, as well as beneficial to diabetes, it is worthy to address proficiency of this indoleamine to the diabetic erythrocytes. In summary, this review has discussed the fostering role of melatonin in hyperglycaemia and encouraged further investigation related to the molecular pathways of melatonin on glucose metabolism.

Authors: Hassan Amal S. , Abdul-Moniem Ibrahim B. , Gad Khater A. E.
Published: June 2020

This paper introduces a new generalization of moment exponential (or length biased) distribution. The new model is referred to as generalized transmuted moment exponential distribution. This model contains some new existing distributions. Structural properties of the suggested distribution including closed forms for ordinary and incomplete moments, quantile and generating functions and Rényi entropy are derived. Maximum likelihood estimation is employed to obtain the parameter estimators of the new distribution. We illustrate the importance of the new model by means of three applications to real data sets.
NOTA CIENTÍFICA - POTENCIAL FITOTÓXICO DO BIOFERTILIZANTE DA CASCA DE PEQUI (Caryocar brasiliense Comb.)
Authors: Matos Christiano Da Conceição de , Mendes Aretusa Daniela Resende , Colen Fernando , Santos Leonardo David Tuffi , Figueiredo Lourdes Silva de , Martins Ernane Ronie
Published: June 2020

A casca do fruto do pequi representa 80% do seu conteúdo total, sendo geralmente descartada. O uso desse resíduo para a produção de biofertilizante surge como alternativa para o seu aproveitamento. Contudo, a casca do pequi é rica em compostos alelopáticos, o que pode restringir sua aplicação nos campos agrícolas. O objetivo deste estudo foi avaliar se o biofertilizante proveniente da casca dos frutos de pequi pode causar efeitos fitotóxicos e, ou interferir no crescimento de plantas de pepino (Cucumis sativus L.). O delineamento experimental utilizado foi o inteiramente casualizado, no esquema fatorial 5 x 2 (doses x pH) com quatro repetições. Os tratamentos corresponderam às doses de biofertilizante por litro de substrato: 0 (controle), 10, 20, 40 e 80 mL, com e sem correção do pH do efluente. As doses de biofertilizante não influenciaram o crescimento e produção da massa fresca e seca da parte aérea e massa fresca das raízes, porém, levaram a um aumento linear de massa seca das raízes do pepino. A correção do pH do bioferilizante favoreceu somente o crescimento inicial em altura do pepino. A acidez do biofertilizante não influenciou o acúmulo de massa fresca e seca dessa planta. O biofertilizante da casca do pequi não causou fitotoxicidade as plantas de pepino, independente da dose. Provavelmente, o processo de fermentação para obtenção do biofertilizante é suficiente para degradar ou tornar possíveis compostos tóxicos indisponíveis. Isso sugere que esse biofertilizante pode ser utilizado em cultivos comerciais. Todavia, em decorrência da baixa disponibilidade de nutrientes, o biofertilizante da casca de pequi contribui pouco para o crescimento da planta.

Published: June 2020

The most recent research is showing the importance and suitability of neural networks for medical image processing tasks. Nonetheless, their efficiency in segmentation tasks is greatly dependent on the amount of available training data. To overcome issues of using small datasets, various data augmentation techniques have been developed. In this paper, an approach for the whole heart segmentation based on the convolutional neural network, specifically on the 3D U-Net architecture, is presented. Also, we propose the incorporation of the principal component analysis as an additional data augmentation technique. The network is trained end-to-end, i.e., no pre-trained network is required. Evaluation of the proposed approach is performed on CT images from MICCAI 2017 Multi-Modality Whole Heart Segmentation Challenge dataset, delivering in a three-fold cross-validation an average dice coefficient overlap of 88.2% for the whole heart, i.e. all heart substructures. Final segmentation results show a high accuracy with the ground truth, indicating that the proposed approach is competitive to the state-of-the-art. Additionally, experiments on the influence of different learning rates are provided as well, showing the optimal learning rate of 0.005 to give the best segmentation results.

Authors: Bajić Filip , Job Josip , Nenadić Krešimir
Published: June 2020

Data visualization is developed from the need to display a vast quantity of information more transparently. Data visualization often incorporates important information that is not listed anywhere in the document and enables the reader to discover significant data and save it in longer-term memory. On the other hand, Internet search engines have difficulty processing data visualization and connecting visualization and the request submitted by the user. With the use of data visualization, all blind individuals and individuals with impaired vision are left out. This article utilizes machine learning to classify data visualizations into 10 classes. Tested model is trained four times on the dataset which is preprocessed through four stages. Achieved accuracy of 89 % is comparable to other methods’ results. It is showed that image processing can impact results, i.e. increasing or decreasing level of details in image impacts on average classification accuracy significantly.

Exploring Marginalities: Making Sense of Affective Knowledge in Home Movies through Collaborative Methods
Authors: Lupu Ruxandra
Published: June 2020

This work deals with the topic of home movies, usually defined as a form of naïve cinema. Attempting to broaden the scope of analysis possible for the home movie, itself consisting of a form characterised by a lack of rules that render it naïve, my research pays particular attention to characteristics of difference and creativity in the home movie, rather than those aspects rendering it a hard-to-define style. To this aim, I deploy participatory approaches as forms of collaborative ideas-making, and this research statement outlines a workshop held at De Montfort University as part of the Cracking the Established Order conference that explored ways to establish a dialogue with the archive of home movies that at the same time presented new ways to speak about this archive. A core component of this process is the use of creative and imaginative methods such as writing or drawing in combination with philosophical concepts. The knowledge gained through this workshop takes the shape of a multimedia video, representing a sort of artistic statement of the entire working process and its outcome. The multimedia video becomes ultimately an expression of what the home movie means and how it comes about.

Published: June 2020

Fiber Reinforced Polymers (FRPs) have wide applications in the field of concrete construction due to their superior performance over conventional materials. This research focuses on the structural behavior of steel tube FRP jacket–confined concrete (STFC) columns under axial concentric loading and proposes a new empirical equation for predicting the axial load-carrying capacity of STFC columns having thickness of FRP-fabric ranging from 0.09 mm to 5.9 mm. A large database of 700 FRP-confined concrete specimens is developed with the detailed information of critical parameters, i.e. elastic modulus of FRPs (Ef), compressive strength of unconfined concrete (fc’o), diameter of specimen (D), height of specimen (H), total thickness of FRPs (N.tf), and the ultimate strength of confined concrete (fc’c). After the preliminary evaluation of constructed database, a new empirical model is proposed for the prediction of axial compressive strength of FRP-confined specimens using general regression analysis by minimizing the error functions such as root mean squared error (RMSE) and coefficient of determination (R2). The proposed FRP-confinement strength model presented higher accuracy as compared with previously proposed models. Finally, an equation is proposed for the predictions of axial load carrying capacity of STFC columns. For the validation of proposed equation, an extensive parametric study is performed using the proposed nonlinear finite element model (FEM). The FEM is calibrated using the load-deflection results of STFC columns from literature. A close agreement was observed between the predictions of proposed finite element model and proposed capacity equation.

Online formative assessment is still challenging although it is getting an increased attention as a significant tool for diagnosing and analysing students’ motivation and achievement in various education domains. This research examines the effects of an online formative assessment tool (OFAT) about science motivation and achievement in second-year students’ university education during four consecutive academic years, 2014 to 2018. A research on the basis of a randomized experimental design was conducted that assigned groups used an OFAT along with various assessments that students participated. A total of 311 students enrolled in the subject take part in the research, respectively 94, 89, 59 and 71 students. Particularly, the OFAT is offering feedback from students, feedback from lecturers and adaptive assignments. Here, data contained student motivation survey data, standardized achievement pre- and post-test data and students’ log records. The results of multiple tier analyses exposed positive effects about students’ motivation and achievement. Based on usage measurements, students’ intensity offers the positive effects about students’ motivation and achievement. Furthermore, along with overall students’ improved performance, the effects of high-performing students’ achievement were higher. Therefore, the results acquired meaningfully contribute to recover main drawbacks and difficulties of traditional science learning programs. Keywords: adaptive assignment, formative assessment, teaching/learning methodologies, university science education.

The location is in Percut Village, Percutseituan District, Deliserdang Regency. The background that is used as a reference for this research begins with the understanding that the urgency of villages in development in Indonesia is so urgent. The village is given authoritative to grow and develop in line with the development of its own community. Furthermore, the village holds millions of pieces of knowledge of the virtues of life and harmony of local wisdom that should be maintained, can be recognized from the mantra of three orders, namely; ordinances, manners, and manners (Zamroni, 2017). This kind of thinking construction is important to restate in order to examine the current relationship between the village government and the community (social institutions). Social institutions as partners of the Village Government have a very strategic role; start to formulate participatory development plans, implement, control, utilize, maintain and develop participatory development, mobilize and develop participation, mutual cooperation and community self-help, and foster dynamic development of the community in the context of community empowerment. Seeing the huge role that village community institutions have, it is important and interesting that this research is carried out to see the existence of community institutions as village government partners in the participatory development process. With this research, it will provide reference data for stakeholders related to community institution empowerment. In addition, it is an academic study in public policy and provides input to the village government regarding the reference to the model of community institution empowerment as a partner of the village government in order to work together to manage development in a participatory village. As for answering the problem of this study using qualitative methods and types of research with a descriptive approach. The targeted research output is a journal article and as a follow up will create a model in the institutionalization of village community organizations.

Modeling of Lizard Skin Pattern by Cellular Automaton
Authors: Grabec Igor , Sok Ada Elizabeta
Published: June 2020

Properties of lizard skin pattern (LSP) comprised of light and dark scales are characterized statistically and compared with the corresponding properties of a random binary field (RBF). The similarity function of these fields exhibits an outstanding peak that indicates their stochastic character. Stochastic properties are still more generally indicated by the probability distribution of scales in hexagonal cells comprised of a center and ring. It shows that similar scales are grouped together in LSP, but not in RBF. This difference is characterized by the conditional probability that reveals why LSP appears more striped than RBF. For generation of fields resembling LSP the cellular automaton (CA) is adapted to LSP by the non-parametric regression. Its deterministic performance is demonstrated by the operation on RBF. By adding a random number generator to this model the deterministic CA is generalized to a probabilistic one. Its actions cause more expressive changing of the input field as the actions of the deterministic CA.
Radiation of Charge Moving Between Two Planar Periodic Wire Structures
Authors: Gurnevich E. A. , Moroz I. V.
Published: June 2020

The Smith-Purcell radiation of a charged particle moving in a periodic structure is analysed theoretically. The considered structure consists of two planar diffraction gratings with different periods which are formed by parallel conducting wires. The analytical expression for the spectral-angular distribution of radiation is obtained. It is shown that the angular distribution of radiation can be made narrower by using two gratings instead of one, and radiation intensity can be manipulated by parallel relative shift of gratings. The obtained results are of great importance for the research and development of high power radiation sources based on volume free-electron lasers.
Prediction of Electropulse-Induced Nonlinear Temperature Variation of Mg Alloy Based on Machine Learning
Authors: Yu Jinyeong , Lee Myoungjae , Moon Young Hoon , Noh Yoojeong , Lee Taekyung
Published: June 2020

Electropulse-induced heating has attracted attention due to its high energy efficiency. However, the process gives rise to a nonlinear temperature variation, which is difficult to predict using a traditional physics model. As an alternative, this study employed machine-learning technology to predict such temperature variation for the first time. Mg alloy was exposed to a single electropulse with a variety of pulse magnitudes and durations for this purpose. Nine machine-learning models were established from algorithms from artificial neural network (ANN), deep neural network (DNN), and extreme gradient boosting (XGBoost). The ANN models showed an insufficient predicting capability with respect to the region of peak temperature, where temperature varied most significantly. The DNN models were built by increasing model complexity, enhancing architectures, and tuning hyperparameters. They exhibited a remarkable improvement in predicting capability at the heating-cooling boundary as well as overall estimation. As a result, the DNN-2 model in this group showed the best prediction of nonlinear temperature variation among the machinelearning models built in this study. The XGBoost model exhibited poor predicting performance when default hyperparameters were applied. However, hyperparameter tuning of learning rates and maximum depths resulted in a decent predicting capability with this algorithm. Furthermore, XGBoost models exhibited an extreme reduction in learning time compared with the ANN and DNN models. This advantage is expected to be useful for predicting more complicated cases including various materials, multi-step electropulses, and electrically-assisted forming.
Love's Revival: Film Practice and the Art of Dying
Authors: Aaron Michele
Published: June 2020

Dying serves so often within the narratives of Western popular culture, as an exercise in self-improvement both to the individual dying and to those looking on. It enlightens, ennobles and renders exceptional all those affected by it. Though mainstream cinema's “grammar of dying” is mired in similar myths, film has the potential to do dying differently: it can, instead, connect us, ethically, to the vulnerability of others. The aim of this article is to pursue this potential of film. Using the mainstream grammar of dying as a starting point, I will consider how the moving image, and this ethical potential, is harnessed within two hybrid-media pieces about a loved-one's decline and death: George Saxon's art installation, “A Record of Undying” (2014) and photographer Briony Campbell's short film The Dad Project (2009). While these works will be located within the traditions and transformations of moving image practice, the primary concern here is with how such emotionally resonant pieces navigate our relation to, and responsibility for, our own and others' harsh realities. In this way, the question of ethics is grounded not in the solipsistic circuits of affective modes – whether as the catharsis or betterment of mainstream myths, or what Jane Stadler privileges as the ethical effects of empathy – but in something more inherently, more inevitably, political.

The central character of Denis Villeneuve's 2016 film Arrival, Dr. Louise Banks (Amy Adams), is a linguist tasked with deciphering a logographic alien language in time to avert a seemingly impending global war. I argue that the alien heptapods' logographs exemplify the understanding of language advanced by Jacques Derrida in seminal texts such as Of Grammatology (1976), while also engaging some of the themes concerning time and gift-giving that he develops in later, more explicitly political works. Derrida argues that written signifiers, rather than being a mere vehicle for representing speech, confer their own, supplemental meaning onto communication. Furthermore, he emphasizes that writing is not bound by the same linear temporality as spoken utterances, inasmuch as it is inscribed in a format which allows it to be revisited repeatedly. The significance of this disruption of linear temporality becomes clear in Derrida's later works such as Specters of Marx (1994) and On Cosmopolitanism (2001), where he describes such disruption as a necessary condition for the type of political change he believes is needed in the world. The ability to experience time in a nonlinear fashion allows Banks to prevent the looming war, in an illustration of the connection that Derrida draws between time, violence, and politics. However, it also puts humanity in the heptapods' debt, thus exemplifying the paradox of genuine gift-giving that Derrida claims is impossible. Despite the complex ethical questions it invokes, however, the unique nature of the gift in Arrival signals that this gift might be a genuinely altruistic offering after all.
How Islamic is an Islamic State: A Theoretical Debate on Islamic Political Order
Authors: Stanizai Zaman
Published: June 2020

The Muslim world is at the bottom rung of participatory democracy, representative governance, and political stability in comparison to the rest of the world. Prevalent and perpetual social disintegration, economic stagnation, and resistance to modernity are all problems in search of answers whose validity and relevance are constantly questioned. Some have vested hopes in the ideal of an ‘Islamic state,’ but very few have defined such a loosely defined state, and even fewer have critically analyzed or offered its theoretical parameters. In this regard, Islamist political activism suffers from a theoretical disconnect with the present political reality. They pursue two divergent paths: regression to a largely irrelevant political past or digression from historical models that the reformists claim to champion. Meanwhile, the crisis persists. In this writing, we delineate the inconsistencies between these arguments.

The use of chemical insecticides in the long term and high frequency will suppress insects (mosquitoes) and vectors to be tolerant until resistant. Reports of resistance from various species of mosquitoes found in multiple countries even occur in Indonesia in Surabaya. This study aimed to analyze the effect of granules bioinsecticides on the mixture of srikaya seeds (A. squamosa) and betel leaf (P. beetle) on the histopathology of mice (M. musculus) using true-experimental (the post-test only group design). Sample taken by simple random sampling and grouped into each control group and the treatment group totaling 25 mice. Data were analyzed using simple linear regression test. The results showed an overall p-value >0.05, meaning that there was no bioinsecticide effect of a mixture of betel leaf granules (Piper beetle) and srikaya seeds (Annona squamosa) on the histopathology of the kidney of mice (Mus musculus). Required safety testing of target animals in addition to mice and a preliminary examination is needed before the research is conducted so that the results are valid

Modelling of Harvesting Machines’ Technical Parameters and Prices

Published: June 2020

Technical and performance parameters of agricultural machines directly impact the operational efficiency and entire crop production. Sometimes, overestimation of technical and dimensional parameters of harvesting equipment is carried out with the intention of enhancing the operational efficiency, but this approach might turn out to negatively impact productivity due to unbalanced system design, and ultimately lead to financial losses. Therefore, a balanced preliminary estimation of technical parameters of equipment needs to be carried out before investment quantification, especially on the large capital-intensive machinery units, such as harvesting systems. In addition, availability of ready to use, simplified models for the price estimation from input technical parameters would reduce the complexity involved in this latter analysis. The current study is an attempt to provide tools to address these issues. A large dataset of combine and forage harvesters has been analyzed to investigate relevant parameter-to-parameter and parameter-to-price relations. The study of the available data allowed the determination of indicative models for the estimation of machine price, power, weight, tank capacity and working width. A significant correlation between power and price (R2 > 0.8) has been observed for two groups of harvesting machines. For combine harvesters, satisfactory correlations were found between power and weight, and power and tank capacity. A regression model for combine harvesters showed a satisfactory behavior at predicting the average working width that can be operated by a given power. On the other hand, for the forage harvesting group, the relation between these quantities has lower values; therefore, for better accuracy of the association, more sophisticated considerations should be incorporated, taking into account other parameters.

The exposure of tomato fruits to unfavorable environments during the postharvest could result in severe losses along the supply chain. In this research, four tomato cultivars were stored in a controlled chamber under three levels of postharvest conditions to investigate the effects of delayed cooling on selected physicochemical quality parameters of the tomatoes. The tomato cultivars were subjected to three postharvest treatments: Immediate storage (IS) at harvest day; delayed storage (DS), leaving tomatoes without cover for one day; and under cover (DSC), separately in a greenhouse, and then stored in a controlled chamber at a temperature of 10 ± 1 °C and relative humidity of 90% ± 3%. Fresh weight, firmness, total soluble solids (TSS), and hue angle (h°) were examined over 15 days, every 5 days. Among the tomato cultivars, Cherry (7160), treated under DS showed the highest weight loss (13.01%) and firmness loss (42.14%) after 15 days of storage. Dabol (large) tomatoes treated with DS showed higher changes in TSS (°Bx) values (4.79 to 5.76). Low changes in hue angle values were found in IS-treated Cherry (7160) tomatoes at the end of the storage period. Overall quality changes were slower for all tomato cultivars treated with IS than with other treatments throughout the storage period. This study indicated the importance of reducing cooling delays to maintain the quality during the postharvest and prolong storage of harvested tomatoes.

For guar, a well-known drought and heat-tolerant industrial legume with a spring–summer cycle, limited research has been conducted into measuring the effects of drought on yield potential. A two-year field experiment was conducted to explore the effects of different irrigation regimes on yield, yield components and water use efficiency (WUE) on five cultivars of guar (Kinman, Lewis, Matador, Monument, and Santa Cruz) in a semi-arid Mediterranean environment. Three different water replenishment levels were used: fully irrigated (IH, 100% of the ET), and 50% (IM) and 25% (IL) irrigated. Seed yields ranged from 1.24 (IL) to 3.28 t ha−1 (IH) in 2011, and from 0.98 (IL) to 2.88 t ha−1 (IH) in 2012. Compared to IH, the two-year average seed yield reductions for IL and IM were 49% and 26%, respectively. Lewis and Santa Cruz showed significantly greater grain yields under fully-watered and water-limited conditions. The number of pods per plant achieved the highest positive direct effects on seed yield (r = 0.924***). The highest values of water use efficiency were observed in the IL water regime (1.44 kg m−3 with increments in improved water use efficiency of +34 and +95% when compared with IM and IH, respectively).
Size Matters: Zoo Data Analysis Shows that the White Blood Cell Ratio Differs between Large and Small Felids

The total number of white blood cells (WBCs) is related the immune system. In mammals, it is affected by the body mass, but it is unclear how the numbers of different WBC types correlate with this parameter. We analyzed the effect of body mass on WBC number and ratio in felids, where species are similar in diet (warm-blood vertebrates) and reproductive strategy (promiscuity). Based on zoo veterinary data (ZIMS database) we analyzed the effect of body mass on WBC number and neutrophils/lymphocytes ratio in 26 species of felids. The number of WBCs correlated with the body masses of animals: large cats had more WBC, which may be due to greater risks of infection associated with larger body surface, lifespan and home range size. For the first time we found obvious differences in the number of WBC types. Large cats also had more neutrophils and monocytes but fewer lymphocytes than smaller cats. The ratio of neutrophils to lymphocytes is greater in large felids. This phenomenon may be related to diet (relative prey size and kill utilization time), which suggests regular contact of large cats with bacterial and protozoal pathogens in contrast to the small cats.
