Published: July 2020

Context. Apparent deviations between properties of dwarf galaxies from observations and simulations are known to exist, such as the “Missing Dwarfs” problem, the too-big-to-fail problem, and the cusp-core problem, to name a few. Recent studies have shown that these issues can at least be partially resolved by taking into account the systematic differences between simulations and observations.
Aims. This work aims to investigate and address any systematic differences affecting the comparison of simulations with observations.
Methods. To this aim, we analyzed a set of 24 realistically simulated Models of Realistic dwarfs In Action (MoRIA) dwarf galaxies in an observationally motivated way. We first constructed “observed” color-magnitude diagrams (CMDs) of the simulated dwarf galaxies in the typically used V- and I-bands. Then we used the synthetic CMD-fitting method to recover their star-formation histories (SFHs) from their observed CMDs. These solved SFHs were then directly compared to the true SFHs from the simulation star-particle data, mainly in terms of the star-formation rate (SFR) and the age-metallicity relation (AMR). We also applied a dust extinction prescription to the simulation data to produce observed CMDs affected by dust in the star-forming regions. Since future facilities, such as the James Webb Space Telescope and the European Extremely Large Telescope, will focus on the (near)-infrared rather than the optical, we also constructed and analyzed CMDs consisting of the I- and H- bands.
Results. We find a very good agreement between the recovered and the true SFHs of all the simulated dwarf galaxies in our sample, from the synthetic CMD analysis of their V − I versus I as well as the I − H versus H CMDs. Dust leads to an underestimation of the SFR during the last few hundred million years, with the strength and duration of the effect dependent on the dust content. Overall, our analysis indicates that quantities like SFR and AMR derived from the photometric observations of galaxies are directly comparable to their simulated counterparts, thus eliminating any systematic bias in the comparison of simulations and observations.
Statistical deprojection of intervelocities, interdistances, and masses in the Isolated Galaxy Pair Catalog
Authors: Nottale Laurent , Chamaraux Pierre 
Published: July 2020

Aims. In order to study the internal dynamics of actual galaxy pairs, we need to derive the probability distribution function (PDF) of true 3D, orbital intervelocities and interdistances between pair members from their observed projected values along with the pair masses from Kepler’s third law. For this research, we used 13 114 pairs from the Isolated Galaxy Pair Catalog (IGPC).
Methods. The algorithms of statistical deprojection previously elaborated were applied to these observational data. We derived the orbital velocity PDFs for the whole catalog and for several selected subsamples. The interdistance PDF is deprojected and compared to the analytical profiles expected from semi-theoretical arguments.
Results. The PDF of deprojected pair orbital velocities is characterized by the existence of a main probability peak around ≈150 km s−1 for all subsamples of the IGPC as well as for the Uppsala Galaxy Pair Catalog. The interdistance PDFs of both the projected and deprojected data are described at large distances by the same power law with exponent ≈ − 2. The whole distributions, including their cores, are fairly fitted by King profiles. The mass deprojection yields a mass/luminosity ratio for the pairs of M/L = (30 ± 5) in solar units.
Conclusions. The orbital velocity probability peak is observed at the same value, ≈150 km s−1, as the main exoplanet velocity peak, which points toward a possible universality of Keplerian structures, whatever the scale. The pair M/L ratio is just seven times the standard ratio for luminous matter, which does not require the existence of nonbaryonic dark matter in these systems.
A significant mutual inclination between the planets within the π Mensae system
Authors: De Rosa Robert J. , Dawson Rebekah , Nielsen Eric L. 
Published: July 2020

Context. Measuring the geometry of multi-planet extrasolar systems can provide insight into their dynamical history and the processes of planetary formation. These types of measurements are challenging for systems that are detected through indirect techniques such as radial velocity and transit, having only been measured for a handful of systems to date.
Aims. We aim to place constraints on the orbital geometry of the outer planet in the π Mensae system, a G0V star at a distance of 18.3 pc that is host to a wide-orbit super-Jovian (M sin i = 10.02 ± 0.15MJup) with a 5.7-yr period and an inner transiting super-Earth (M = 4.82 ± 0.85M⊕) with a 6.3-d period.
Methods. The reflex motion induced by the outer planet on the π Mensae star causes a significant motion of the photocenter of the system on the sky plane over the course of the 5.7-year orbital period of the planet. We combined astrometric measurements from the HIPPARCOS and Gaia satellites with a precisely determined spectroscopic orbit in an attempt to measure this reflex motion, and in turn we constrained the inclination of the orbital plane of the outer planet.
Results. We measure an inclination of ib = 49.9−4.5+5.3 deg for the orbital plane of π Mensae b, leading to a direct measurement of its mass of 13.01−0.95+1.03 MJup. We find a significant mutual inclination between the orbital planes of the two planets, with a 95% credible interval for imut of between 34.°5 and 140.°6 after accounting for the unknown position angle of the orbit of π Mensae c, strongly excluding a co-planar scenario for the two planets within this system. All orbits are stable in the present-day configuration, and secular oscillations of planet c’s eccentricity are quenched by general relativistic precession. Planet c may have undergone high eccentricity tidal migration triggered by Kozai-Lidov cycles, but dynamical histories involving disk migration or in situ formation are not ruled out. Nonetheless, this system provides the first piece of direct evidence that giant planets with large mutual inclinations have a role to play in the origins and evolution of some super-Earth systems.

AbstractThe present, updated document describes the fourth iteration of recommendations for the hepatic use of contrast enhanced ultrasound (CEUS), first initiated in 2004 by the European Federation of Societies for Ultrasound in Medicine and Biology (EFSUMB). The previous updated editions of the guidelines reflected changes in the available contrast agents and updated the guidelines not only for hepatic but also for non-hepatic applications.The 2012 guideline requires updating as previously the differences of the contrast agents were not precisely described and the differences in contrast phases as well as handling were not clearly indicated. In addition, more evidence has been published for all contrast agents. The update also reflects the most recent developments in contrast agents, including the United States Food and Drug Administration (FDA) approval as well as the extensive Asian experience, to produce a truly international perspective.These guidelines and recommendations provide general advice on the use of ultrasound contrast agents (UCA) and are intended to create standard protocols for the use and administration of UCA in liver applications on an international basis to improve the management of patients.

AbstractThe aim of this study was to investigate the impact of Supervised and Home-based
resistance exercise on the Kynurenine pathway in patients with pancreatic cancer
who underwent surgery and chemotherapy. In the SUPPORT study, adult pancreatic
cancer patients were randomized to intervention programs of 6-month (1) a
Supervised moderate-to-high-intensity progressive resistance training or (2)
unsupervised Home-based resistance training, or (3) to a standard care patient
Control group. Serum levels of kynurenine, tryptophan and IL-6 were assessed for
32 participants before, after 3 months and after 6 months of exercise
intervention. Group differences were investigated using analysis-of-covariance.
Patients in the Supervised training group showed decreased levels of serum
kynurenine and kynurenine/tryptophan ratio (p = 0.07; p
= 0.01 respectively) as well as increased Tryptophan levels (p =
0.05) in comparison to Home-based and Control group over time. The Home-based
exercise group had significant increased kynurenine and
kynurenine/tryptophan ratio levels. IL-6 levels decreased over the first
three months for both intervention groups as well as the Control group
(Supervised: p < 0.01, Home-based: p < 0.010, Control group: p
< 0.01). Supervised resistance exercise might positively regulate the
Kynurenine pathway and downregulate the kynurenine/tryptophan
(indicative of IDO/TDO enzyme) levels, hence modulating the immune
system.
When possible, report a Fisher-exactPvalue and display its underlying null randomization distribution
Authors: Bind M.-A. C. , Rubin D. B. 
Published: July 2020

SignificanceStatistical analyses of randomized experiments often rely on asymptoticPvalues instead of using the actual randomization procedure that led to the observed data. Fisher-exact and asymptoticPvalues can differ dramatically: The former should be preferred because it is calculated using the exact null randomization distribution, which, in small samples, can substantially differ from its approximating Student’stdistribution. Moreover, we may learn something scientifically interesting from examining the shape of the null randomization distribution.
The African hero in Mozambican history: on assassinations and executions – Part I
Authors: Saul John S. 
Published: July 2020

SUMMARY
‘A gun shot in the middle of a concert [is] something vulgar, [yet] something which is impossible to ignore’, writes Stendhal, the greatest of political novelists. The same is true of death – especially of death by assassination and death by execution – in the political analysis of Africa. For, as argued here in two linked texts, one in this issue of the Review of African Political Economy, ROAPE, and a second in the following issue of ROAPE, such intrusions of planned and orchestrated deaths are seen to have provided key moments in African politics (and, not least, in Mozambican politics), albeit moments that have too seldom been allotted the theoretical attention they warrant or debated with the seriousness they deserve. In this Part I (and its subsection 1) of the present contribution to the Debate section of ROAPE, different ways of approaching this matter are first reflected upon. Then, in subsection 2, some of the issues so raised are exemplified with reference to the first of the two most pertinent assassinations in Mozambican history, the assassination in 1969 (in Dar es Salaam) of Frelimo’s first president, Eduardo Mondlane. In Part II of this essay (to appear in the next issue of ROAPE), the discussion of Mondlane and his assassination will be complemented by a reflection on the assassination in 1986 of his immediate successor as Frelimo president (and the eventual first president of Mozambique), Samora Machel. Several other related matters will also be discussed in this Part II, matters I will anticipate at the end of this first part (below). But such sections, too, will help us to bring into focus the main theme of this two-part article and of the subsequent debate it seems to stimulate, which are: just what difference can the several assassinations and executions that have scarred Mozambican history be thought to have made to the shaping of longer-term outcomes in the country’s history; and what, more generally, can we hope to learn from such a closer examination of the ‘what ifs’ of history?
Extractivism, exclusion and conflicts in Senegal’s agro-industrial transformation
Authors: Benegiamo Maura 
Published: July 2020

ABSTRACT
In the last two decades, the promotion of agro-industry has become a dominant developmental imperative on the African continent, leading to efforts to involve private-sector actors. This article examines the political economy and ecology of agro-industry in the Senegal River delta, focusing on local-level reactions to Senegalese initiatives aimed at attracting foreign investors in agriculture. The argument is that Senegal is witnessing the emergence of an agro-extractivist pattern that replaces earlier development objectives – such as peasants’ integration into the national economy – with the new imperative of the integration of territories into global capitalism. The article presents empirical evidence on three main consequences of the increased presence of agro-industry: a process of change in land property and access; the end of public support to peasant farmers; and an intensified marginalisation of pastoralism. Colonial heritage and the role of local resistances in shaping and mediating this developmental strategy are also discussed.

Published: July 2020

Abstract
Iridology, which is an alternative diagnosis that links iris patterns, colour, tissue weakness, damage and other characteristics, which can obtain evidence about the patient’s systemic health. Iridology can be integrated with the best technology such as computer vision for accurate identification of abnormalities in various organs of the human body. By extracting information from iris image data. Image quality improvement is needed because often the images tested have poor quality, for example images experiencing lighting, noise (noise), the image is too dark or bright, the image is not sharp, and blurred. In this research, the iris image quality was improved by the method of HE, AHE and CLAHE. The results of the improvement of 40 iris images obtained an average value of MSE and RSME, the smallest of the three methods is the CLAHE method, so that the CLAHE method is best used for iris image improvement. Overall, based on the PSNR values, the three methods are good for enhancing image contrast because they have an average PSNR of more than 30dB.

Abstract
Nowadays, almost all cellphones are connected to internet and they are referred to as smartphones. Smartphones can be utilized by the garment industry to assist monitoring the production and financial management processes. The purpose of this study is to develop an Android-based mobile application in the “X” garment industry which is integrated with the existing web-based information systems. The application was developed using the Rapid Application Development (RAD) software development method. The program code for the mobile application was created using Android Studio 3 and database access (MySQL DBMS) on the server via Web Service (REST API). Application evaluation was done by two methods, namely System Usability Scaling (SUS) and Black Box Test. The Black Box Test results showed that all application functions were running appropriately, and value of the System Usability Scaling (SUS) test was 83.5. This indicates that the application is feasible to be implemented in the “X” garment industry.

Abstract
Integrated surveillance of ARI disease at Health Office of Jember is still using manual method in reporting in which the officers have to come directly to the Health Office to collect the data. The problem emerged of this manual method is the difficulty of designing the report because the officers have to recap and re-search the data of the report, and the data collection process is often late due to the far distance of the health center to the manual health office. This research was intended to create a design for data recording and reporting system of integrated surveillance of ARI disease in order to facilitate the reporting process to the Health Office. The method used was waterfall method with the stages of need identification, designing system, Website implementation, integration, and testing. This research used qualitative approach, in which the data were collected through the interview, observation, and FGD. The script editors used were PHP program and Sublime Text3. The result obtained from this research was the information system of integrated surveillance report of ARI disease. Thus, it is suggested to increase the distribution of component data related to the integrated surveillance report in order to decide the action planning of ARI disease.

Published: July 2020

Abstract
student learning performance influences the quality of a university. One indicator of assessment of student learning performance is the student’s study period. By predicting the student’s study period, universities can evaluate performance to strive to improve the quality of universities. Data mining is one of the choice technique in terms of predictions. But, each algorithm in data mining has the advantages of each, including Decision Tree and Naïve Bayes Algorithm which were tested in this research. This research shows Decision Tree is better than Naïve Bayes Algorithm to be the best choice to predicting study period with accuracy level tested for several ratios of training data and test data are 60:40,65:35,70:30,75:25 and 80:20 produce the highest accuracy values obtaines by decision tree with accuracy values are 90%, 89,14%, 89,3%, 88,8% and 88%. But, the amount of training data in this research does not affect the value of accuracy. This is shown from the value of accuracy in a certain ratio is very small but sometimes also the value of accuracy is high

Published: July 2020

Abstract
This study aims to carry out the monitoring process of wireless local area network (WLAN) microtics using the Dude application at Musamus University. It is expected that the monitoring results can be in the form of messages / notifications to network administrators. Network monitoring will be increasingly difficult if the computer network topology in an institution is very broad and complex. The network devices used in this study are the Mikotik operating system with the Dude tools with the specifications of Mikrotik RB433, The Dude server and The Dude Client. Based on the results of the implementation and testing carried out on the WLAN network of Musamus University, it was found that the use of The Dude Application can make it easier for network admins to know the position of the proxy router that has trouble, up and down on the proxy router. Another advantage is that the admin simply monitors the network on the server because if there is trouble or the system down the admin gets a notification in the form of an email from the Dude.
