Feed utilization efficiency is one of the problems that often faced by tiger shrimp (Penaeus monodon Fabricus) farmers, which is 40-60% of production costs used for feed. The efficiency of feed can be improved by the addition of the bromelains in the feed, which can hydrolyze proteins into simpler compounds to increase the digestibility of the feed protein. This study aims to examine the effect of bromelains in feed on protein digestibility (ADCp), feed utilization efficiency (EPP), and growth (RGR) of tiger shrimp. Tiger shrimp with an average weight of 2.8 ± 0.26 g / individual was obtained from the Brackish Water Aquaculture Development Centre (BBPBAP), Jepara. There were 6 treatments adding bromelains in the feed, A (0%), B (0.2%), C (0.4%), D (0.6%) and E (0.8%). Observation parameters, including ADCp, EPP, PER, RGR, SR, and water quality parameters. The results showed that the addition of the bromelains in feed increased ADCp, EPP, PER, RGR, but had no effect on the SR of tiger shrimp. Bromelains (0.4% / kg) of feed is the optimal dose of ADCp, EPP, and RGR, resulting in a maximum value of 82.59%, 88.17%, and 5.24% / day. Permasalahan yang sering dihadapi pembudidaya udang windu (Penaeus monodon Fabricius) adalah efisiensi pemanfaatan pakan yang belum maksimal sehingga hampir 40-60% dari total biaya produksi untuk biaya pakan. Efisiensi pemanfaatan pakan dapat ditingkatkan dengan penambahan enzim bromelin dalam pakan yang mampu menghidrolisis protein menjadi senyawa yang lebih sederhana sehingga dapat meningkatkan daya cerna protein pakan. Penelitian ini bertujuan mengkaji pengaruh enzim bromelin dalam pakan terhadap kecernaan protein (ADCp), efisiensi pemanfaatan pakan (EPP) dan pertumbuhan (RGR) udang windu. Hewan uji berupa udang windu dengan bobot rata-rata 2,8±0,26 g/ekor diperoleh dari Balai Besar Perikanan Budidaya Air Payau (BBPBAP), Jepara sebagai tempat penelitian. Terdapat 6 perlakuan penambahan enzim bromelin dalam pakan yaitu A (0 %), B (0,2 %), C (0,4 %), D (0,6 %) dan E (0,8 %). Pengamatan parameter meliputi ADCp, EPP, PER, RGR, SR dan parameter kualitas air. Hasil penelitian menunjukkan bahwa penambahan enzim bromelin dalam pakan meningkatkan ADCp, EPP, PER, RGR, namun tidak berpengaruh pada SR udang windu. Enzim bromelin 0,4%/kg pakan merupakan dosis optimal pada ADCp, EPP dan RGR menghasilkan nilai maksimal sebesar 82,59%, 88,17% dan 5,24%/hari.

Published: July 2020

Abstract
This paper describes an endeavour to build natural language processing (NLP) tools for Runyakitara, a group of four closely related Bantu languages spoken in western Uganda. In contrast with major world languages such as English, for which corpora are comparatively abundant and NLP tools are well developed, computational linguistic resources for Runyakitara are in short supply. First therefore, we need to collect corpora for these languages, before we can proceed to the design of a spell-checker, grammar-checker and applications for computer-assisted language learning (CALL). We explain how we are collecting primary data for a new Runya Corpus of speech and writing, we outline the design of a morphological analyser, and discuss how we can use these new resources to build NLP tools. We are initially working with Runyankore–Rukiga, a closely-related pair of Runyakitara languages, and we frame our project in the context of NLP for low-resource languages, as well as CALL for the preservation of endangered languages. We put our project forward as a test case for the revitalization of endangered languages through education and technology.
Construction grammar and creativity: Evolution, psychology, and cognitive science
Authors: Hoffmann Thomas 
Published: July 2020

AbstractCreativity is an important evolutionary adaptation that allows humans to think original thoughts, to find solutions to problems that have never been encountered before, and to fundamentally change the way we live. Recently, one important area of creativity, namely verbal creativity, has attracted considerable interest from constructionist approaches to language. The present issue builds on this emerging field of study and adds an interdisciplinary perspective to it by also presenting the view from cognitive literary studies as well as psychology. First, however, this introduction surveys the recent issues arising in constructionist studies of verbal creativity.
Austerity and fragmentation: Dynamics of Europeanization of media discourses in Greece and Italy
Authors: Bee Cristiano , Chrona Stavroula 
Published: July 2020

Abstract
This article investigates media representations of the European financial crisis in Greece and Italy. We study the Euro crisis as an ‘emergency situation’ with domino effects, where media played a central role in shaping communication practices at the national level as well as between the two countries. Drawing upon vertical and horizontal dynamics of Europeanization, we map the convergences and divergences in media discourses that surround the period 2011–2015. In doing so, we elaborate a qualitative analysis of newspaper articles focusing, in particular, on the themes of austerity and the fragmentation of Europe. Our argument suggests that national public spheres in times of transnational crisis become increasingly nationalized; yet under certain circumstances such as when the supranational infrastructure is the target of blame, they converge, opening the path toward a transnational discursive dialogue.

Abstract
PubChem (https://pubchem.ncbi.nlm.nih.gov) is one of the top five most visited chemistry web sites in the world, with more than five million unique users per month (as of March 2020). Many of these users are educators, undergraduate students, and graduate students at academic institutions. Therefore, PubChem has a great potential as an online resource for chemical education. This paper describes the PubChem Periodic Table and Element pages, which were recently introduced to celebrate the 150th anniversary of the periodic table. These services help users navigate the abundant chemical element data available within PubChem, while providing a convenient entry point to explore additional chemical content, such as biological activities and health and safety data available in PubChem Compound pages for specific elements and their isotopes. The PubChem Periodic Table and Element pages are also available as widgets, which enable web developers to display PubChem’s element data on web pages they design. The elemental data can be downloaded in common file formats and imported into data analysis programs (e.g., spreadsheet software, like Microsoft Excel and Google Sheets, and computer scripts, such as python and R). Overall, the PubChem Periodic Table and Element pages improve access to chemical element data from authoritative sources.

Abstract
The borehole electrical imaging log offers general visual borehole wall, leaving no doubt that the conductivity contrast is sufficient to obtain a qualitative gain-size distribution of rocks. In this study, an automatic grain-size classification method is proposed using gray values of borehole electrical images from Baikouquan Formation in Mahu Depression. The first stage is comparing electrical images with cores. Gravels, sands, silts and clays are all discovered in the cores. The gravels are “mottled” in electrical images, and the bigger the spots, the coarser the gravels. The images of sands are homogeneous bright colored, and the coarser the sandy grains, the brighter the images. The electrical images of silts and clays are homogeneous brown and dark-brown colored. The second stage is auto-discriminating four categories of grain sizes roughly using averages and variances of gray values. The variances of gray values of gravels are high, whereas those of sands are medium. The gray averages of silts are between 160 and 220, whereas those of clays are larger than 200. The third stage is auto-classifying three kinds of gravels or sands finely using frequency distribution of gray values. The gray values of frequency peaks of cobbles are less than 50 and frequencies are larger than 15%, whereas those of pebbles are less than 50 or larger than 200 and frequencies are between 10% and 20%; almost gray frequencies of granules are less than 10%. The dominated gray values of coarse sandstones, medium sandstones and fine sandstones are less than 50, between 50 and 160 and ranged from 160 to 240, respectively. The proposed method is demonstrated to be useful and fast to auto-classify grain size of various rocks in conglomeratic environments.

Published: July 2020

Abstract

Background
Normal development of the human placenta, referred to as villous tree maturation, entails formation of the vasculosyncytial membranes. These structures develop by the approximation of syncytiotrophoblasts with the villous capillary endothelium and constitute the most efficient sites of gaseous exchange in the placenta. Defective maturation of the villous tree can lead to deficient vasculosyncytial membranes, implicated in the high incidence of hypoxic complications. Hypoxia, in turn, can stimulate production of erythropoietin, whereby increased fetal plasma or amniotic fluid concentrations of this hormone reflect fetal hypoxemia. The current study was undertaken to determine whether delayed villous maturation is associated with changes in amniotic fluid erythropoietin concentrations.

Methods
Placental histologic examination was performed using hematoxylin and eosin. Subsequent to histologic assessment of delayed villous maturation, the diagnosis was confirmed with CD-15 immunohistochemistry. The controls (n = 61) were pregnancies without villous maturation abnormalities, and cases (n = 5) were pregnancies with delayed villous maturation. Amniotic fluid erythropoietin concentrations were measured using a specific immunoassay.

Results
Concentrations of erythropoietin in the amniotic fluid (1) of controls were less than the limit of detection and (2) of cases with delayed villous maturation were significantly higher than those of controls (P-value = 0.048).

Conclusion
Delayed villous maturation is associated with higher concentrations of amniotic fluid erythropoietin.

Peacekeeping after Covid-19
Authors: Dorussen Han 
Published: July 2020

Abstract
The 2020 Covid-19 pandemic may not be a game changer for future peacekeeping and humanitarian operations, but it is likely to strengthen developments that have been on-going since the early 2010s. Since then, major global and regional powers have increasingly pursued self-interested policies, interventions have become less accepted by host countries, and the UN is more financially constrained. These developments all point towards fewer and smaller interventions. Responses to Covid-19 so far suggest these trends to continue. Arguably, this hampers effective and collaborative action against global challenges such as Covid-19.
Subpixel matching method for remote sensing image of ground features based on geographic information
Authors: Chen Chen 
Published: July 2020

AbstractIn order to solve the problem of large error of subpixel matching and poor filtering effect in traditional methods, a subpixel matching method based on geographical information is proposed. First, the image quality of the remote sensing image is enhanced by the image enhancement method based on light energy allocation. Then, the boundary geographic information is extracted by the improved thresholding segmentation algorithm based on histogram exponential convex hull for the enhanced remote sensing image of ground features. Based on the extracted geographic information, by matching the boundary image with the function measurement method, the center coordinates of the image block corresponding to the actual measurement map and the reference submap which achieve the best matching are obtained. According to the corresponding geometric transformation relationship between the measured image and the reference image, the subpixel matching of the measured remote sensing image and the reference image can be carried out under the least-square-error criterion. The experimental results show that the enhancement performance and noise filtering performance of the proposed method are better than those of the same type of method, the matching residual is very small, the matching accuracy is high, and the application value is significant.
Understanding hormonal crosstalk in Arabidopsis root development via emulation and history matching
Authors: Jackson Samuel E. , Vernon Ian , Liu Junli , Lindsey Keith 
Published: July 2020

AbstractA major challenge in plant developmental biology is to understand how plant growth is coordinated by interacting hormones and genes. To meet this challenge, it is important to not only use experimental data, but also formulate a mathematical model. For the mathematical model to best describe the true biological system, it is necessary to understand the parameter space of the model, along with the links between the model, the parameter space and experimental observations. We develop sequential history matching methodology, using Bayesian emulation, to gain substantial insight into biological model parameter spaces. This is achieved by finding sets of acceptable parameters in accordance with successive sets of physical observations. These methods are then applied to a complex hormonal crosstalk model for Arabidopsis root growth. In this application, we demonstrate how an initial set of 22 observed trends reduce the volume of the set of acceptable inputs to a proportion of 6.1 × 10−7of the original space. Additional sets of biologically relevant experimental data, each of size 5, reduce the size of this space by a further three and two orders of magnitude respectively. Hence, we provide insight into the constraints placed upon the model structure by, and the biological consequences of, measuring subsets of observations.
Capital mobility in commodity-exporting economies
Authors: Polbin Andrey , Rybak Konstantin , Zubarev Andrey 
Published: July 2020

Abstract
This paper studies capital mobility in commodity-exporting economies. These countries substantially depend on world commodity prices and have rather high level of savings on average, so it is naturally to assume that they demonstrate special patterns of capital mobility. Our main hypothesis is that constraints on capital mobility in this group of countries depend upon the level of savings compared to the level of investments. In particular, with high savings that follow higher world demand and higher commodity prices, financing country’s desirable level of investment is not a big deal. At the same time, in the case of negative terms of trade shocks these commodity-exporting economies may experience lower savings and higher country risk-premium. This may lead to restrictions on borrowing capital in the global market, resulting in a high correlation between investments and savings. The results of threshold regressions speak in favour of our hypothesis.

Phase-purity was checked by powder X-ray diffraction experiments, which were also utilized to refine the lattice parameters. The structure can be described as composed of layers with a stacking of [PtAl2] (A) and [RE

The magnetic properties of the X-ray-pure samples were investigated by susceptibility and magnetization measurements. Gd4Pd9Al24 shows the highest transition temperature to antiferromagnetism of T
N = 22.0(1) K, however, a broad feature is observed. This is in line with a low-dimensional ordering caused by the layer-like structure and the flat honeycomb arrangement of the Gd atoms.

Abstract
—We overview recent data on the mineralogy of oxidizing-type fumaroles of the Tolbachik Volcano (Kamchatka, Russia), with the main focus on the chemical specifics of the minerals. The active fumarole fields of Tolbachik are the most prominent mineral-forming exhalative system of this type in the world. About 350 mineral species, including 123 minerals first discovered here, are reliably identified in the Tolbachik fumaroles. The species diversity and the specifics of this mineralization are due to the unique combination of the physicochemical conditions and mechanisms of its formation: high temperatures, atmospheric pressure, superhigh oxygen fugacity, gas transport of most of chemical elements, and direct deposition of many high-temperature minerals from volcanic gases with a specific geochemical composition, including strong enrichment in alkaline metals and chalcophile (“ore”) elements. Sublimate silicates and minerals of As, Cu, Zn, Mn, Ti, Sn, Sb, Se, Au, Ag, Cs, Tl, and F are briefly described in terms of mineral geochemistry.
