Authors: Klara S , Mahmuddin F , Hariyanto S , Sitepu G , Aman A A 
Published: July 2020

Abstract
One of the most issues on a boat for using energy is resistance. Therefore some energy is needed to be able to overcome the boat resistance. The total resistance depends on the speed of the boat. By reducing the resistance, it will affect the energy usage on the boat. One way to reduce the boat resistance is by installing a stern flap to the stern. Stern flap is a new addition on the stern appendage. Previous studies, the stern flap was able to reduce the resistance. The reduction of resistance occurred on boats can reduce fuel consumption, so it can be one of the innovations in combating the energy crisis. This study used an experimental method that analyzes the position and size of the stern flap, where each position and size of the flap were tested at the same load. From the results and analysis, it shows that the changing position of the stern flap on the surface of the water will increase the boat speed by 4.62% and the changing size of the stern flap size to 85 × 80 cm will increase the speed of the boat by 3.82%.

Abstract
Traditional wooden fishing boats are still being produced by most of the traditional wooden shipyards in Indonesia specifically in the area of South Sulawesi. Nevertheless, the traditional wooden boat craftsman facing the difficulty of wooden log supply as the main wooden boat material especially for wooden frame construction despite the increasing demand for wooden material for the boat construction. The difficulty to acquire the specific wooden for wooden frame caused by the specific requirements of each wooden frame. They must be in the specific shape according to the specific curvature of each transversal boat section along the boat length. Hence, for the sustainability of wooden boat construction process, alternative material is needed for replacing the certain wooden boat construction component, especially for wooden frames. Fortunately, research relating to the use of alternative material for wooden boat construction have been conducted. The focus of the research is on the use of steel frame to replace the wooden frame on the wooden boat construction. This paper discusses the cost comparison for the fabrication and installation process as well as the material cost of the steel frame to the wooden boat construction with wooden frame to the wooden boat construction. The result shows that the cost for fabricating and installing steel frame is 13% higher to compare to the wooden frame. However, if the total wooden boat construction cost is being considered, the total difference is only 3%.

Abstract
In order to save spaces inside a small-sized fishing boat, the high-pressure flow behind propeller is utilized instead of a special cooling pump to cool the main engine. From the previous study, the system is referred to as the Propeller Flow Cooling System (PFCS). As a continuation of the previous study, the present study conducted more experiments in order to compare the performance of a single and a double intake designs of the PVCS with the same cross-sectional area. The designs with circular and elliptical intakes shapes were measured. The experiments were also conducted at the Circulating Water Channel (CWC) facility. The main parameter which was compared in the experiment and analysis was the flow capacity produced by both designs for various propeller revolution (RPM). The experimental results showed that single intake design has a higher flow capacity than the double intake one which was caused by higher flow losses inside the pipe of single intake design mainly due to higher surface friction as well as an additional elbow joint needed in double intake design. This tendency occurred for both circular and elliptical shapes cases.

Published: July 2020

Abstract
Chicken eggs are one of the commodities that become easily available foodstuffs. The level of egg production in good condition is directly proportional to the capacity of the cage. The process of calculating the amount of egg production becomes a problem for farmers when they want to calculate the amount of egg production in the condition of a chicken coop on a large scale. Smart systems are one form of technological development with the primary goal of producing effective and efficient systems. One area that plays a role in technological development is image processing, eggs are objects with certain color characteristics and pixel scales. In this study, the process of calculating the number of eggs based on color segmentation and selection of pixel scales on eggs and the process of calculating objects using the Connected Component Labeling algorithm of images that have gone through gray-scale and threshold processes and implemented using MATLAB. The trial results show that the object image of an egg is strongly influenced by the size of the image, the intensity of the light, and distance of capturing images. The number of eggs that can be detected in this study depends on the process of segmentation and measurement of the object’s egg scale, in this study it was found that colors other than egg colors and objects that are outside the egg scale will be considered as noise and will not be detected.

Dynamical systems on hypergraphs
Authors: Carletti Timoteo , Fanelli Duccio , Nicoletti Sara 
Published: July 2020

Abstract
Networks are a widely used and efficient paradigm to model real-world systems where basic units interact pairwise. Many body interactions are often at play, and cannot be modelled by resorting to binary exchanges. In this work, we consider a general class of dynamical systems anchored on hypergraphs. Hyperedges of arbitrary size ideally encircle individual units so as to account for multiple, simultaneous interactions. These latter are mediated by a combinatorial Laplacian, that is here introduced and characterised. The formalism of the master stability function is adapted to the present setting. Turing patterns and the synchronisation of non linear (regular and chaotic) oscillators are studied, for a general class of systems evolving on hypergraphs. The response to externally imposed perturbations bears the imprint of the higher order nature of the interactions.
Towards recognizing the light facet of the Higgs boson
Authors: Alves Alexandre , Freitas Felipe F 
Published: July 2020

Abstract
The Higgs boson couplings to bottom and top quarks have been measured and agree well with the Standard Model predictions. Decays to lighter quarks and gluons, however, remain elusive. Observing these decays is essential to complete the picture of the Higgs boson interactions. In this work, we present the perspectives for the 14 TeV LHC to observe the Higgs boson decay to gluon jets assembling convolutional neural networks, trained to recognize abstract jet images constructed embodying particle flow information, and boosted decision trees with kinetic information from Higgs-strahlung

Empire, decoloniality, and the globalization of world music
Authors: Bohlman Philip V. 
Published: July 2020

Abstract
‘Empire, decoloniality, and the globalization of world music’ takes empire and globalization as points of departure, exploring street music in Romania and wedding music in Kolkata—global music performed locally that collapses the difference between world music and traditional folk music. The globalization of world music has been brought about by the development of modern cities into ‘global cities’, improved recording technologies, easy media access, and the expansion of ethnomusicology. The Rough Guides to World Music provide extensive documentation of the postmodern encounter with world music, and perhaps unintentionally act as a guide to recent trends in ethnomusicology.
French philosophy today
Authors: Gaukroger Stephen , Peden Knox 
Published: July 2020

Abstract
Following the 1968 protests, the once-popular Marxism of Althusser declined in relevance. ‘French philosophy today: competing ambitions’ looks at the careers of Althusser’s pupils and successors. Much of twentieth-century French philosophy was a reckoning with phenomenology, which itself had risen as an alternative to existentialism. Some writers worried that phenomenology, as interpreted by Michael Henry and Emmanuel Levinas, was taking an overly theological turn. French philosophers were ready to move on from the Revolution, but ideas about who conferred power in the absence of a religious authority were as relevant as ever and harked back to the ongoing dialogue between philosophy and Christianity.
UglyTrees: a browser-based multispecies coalescent tree visualizer
Authors: Douglas Jordan 
Published: July 2020

Abstract

Summary
Visualization is a vital task in phylogenetics and yet there is a deficit in programs which visualize the multispecies coalescent (MSC) model. UglyTrees (UT) is an easy-to-use program for visualizing multiple gene trees embedded within a single species trees. The mapping between gene and species nodes is automatically detected allowing for ready access to the program. UT can scrape the contents of a website for MSC analyses, enabling the sharing of interactive MSC figures through optional parameters in the URL. If a posterior distribution is uploaded, the transitions between MSC states are animated allowing the visual tracking of trees throughout the sequence.

Availability and implementation
UT runs in all major web browsers including mobile devices, and is hosted at www.uglytrees.nz. The MIT-licensed code is available at https://github.com/UglyTrees/uglytrees.github.io.

Published: July 2020

Abstract

Summary
Dysfunctional regulations of gene expression programs relevant to fundamental cell processes can drive carcinogenesis. Therefore, systematically identifying dysregulation events is an effective path for understanding carcinogenesis and provides insightful clues to build predictive signatures with mechanistic interpretability for cancer precision medicine. Here, we implemented a machine learning-based gene dysregulation analysis framework in an R package, DysRegSig, which is capable of exploring gene dysregulations from high-dimensional data and building mechanistic signature based on gene dysregulations. DysRegSig can serve as an easy-to-use tool to facilitate gene dysregulation analysis and follow-up analysis.

Egg-laying site, fecundity and degree of sexual size dimorphism in frogs
Authors: Silva Nelson Rodrigues , Berneck Bianca V M , da Silva Helio R , Haddad Célio F B , Zamudio Kelly R , Mott Tamí , Nali Renato C , Prado Cynthia P A 
Published: July 2020

AbstractFemale fecundity is an important selective force leading to female-biased sexual size dimorphism (SSD) in frogs. Because anurans exhibit diverse reproductive modes, we investigated whether variation in SSD and fecundity are related with oviposition site. We asked whether arboreal breeding species show pronounced female-biased SSD and if, paradoxically, females have lower fecundity because of the costs of carrying oocytes and amplectant males. Conversely, we tested whether species that deposit eggs in concealed sites show less pronounced SSD, because females do not carry males and space limitation may reduce female size and fecundity. Our results showed that, in general, males were approximately 20% smaller than females. However, for species with hidden oviposition sites, males and females exhibited more similar body sizes and arboreal hylids showed more pronounced female-biased SSD. Overall, fecundity was higher in aquatic breeders, as expected, but in hylids, fecundity was smaller in arboreal breeders, which suggests that arboreality may impose restrictions on fecundity. By analysing SSD in a broader and more specific lineage (Hylidae), we found that reproductive microhabitat may also influence female size and fecundity, playing an important role in the evolution of SSD in frogs at different evolutionary scales.
Gambling in children and adolescents
Authors: Emond Alan M , Griffiths Mark D 
Published: July 2020

Abstract

Introduction
Children are susceptible to problems with gambling because of developmental and cognitive immaturities, as well as a sensitivity to peer pressure and marketing.

Sources of data
This review uses recent UK data from the Gambling Commission and from the Avon Longitudinal Study of Parents and Children, and evidence from recent reviews of gambling in children and adolescents.

Areas of agreement
The prevalence of gambling in children worldwide and in the UK is stable, having generally decreased since 2013. Online gambling is increasing in children and young people. A small minority of adolescents who gamble develop a gambling disorder. Adolescents who have problems with gambling tend to have lower self-esteem and a history of hyperactivity and impulsivity, are more likely to have parents who gamble, report less parental supervision and to use more alcohol than their peers.

Areas of controversy
Children’s access to slot machines, the relationship between gaming and gambling, and social media advertizing of gambling targeting children.

Growing points
An increase in online gambling and in-play sports betting by adolescents and the use of skins betting in video gaming.
Areas timely for developing research: impact on young people of betting on e-gaming. How best to protect children from early exposure to gambling in the current internet age.

Implications for clinicians
Need to be aware of the growing and complex phenomenon of gaming and gambling, and implications for the mental health of children and adolescents. The effective management of gambling disorders in children and adolescents requires close working with families.

Abstract
Retinitis pigmentosa is an inherited neurodegenerative disease of the retina. We investigated smoking as a modifiable environmental factor for the progression of this currently untreatable disease. Clinical data, smoking history, macular function and morphology including visual acuity, visual field sensitivity, ellipsoid zone width and central retinal thickness were investigated. Association between pack × years and these parameters were evaluated using generalized estimating equation models to adjust confounding factors such as age and sex. A total of 410 patients with retinitis pigmentosa (≥20 years old; 209 female) were included, 164 had a smoking history. Patients without smoking history revealed a better visual acuity than smokers (0.39 versus 0.57, P = 0.001). The pack × years index was associated with worse visual acuity and thinner central retinal thickness after adjusting for age and sex (P = 0.0047 and 0.0099, respectively). Visual field and ellipsoid zone width showed a non-significant decline with increasing pack × years. This study indicates an association of smoking with worse macular function and structural integrity in retinitis pigmentosa patients, and hence a potential detrimental effect of smoking on the disease course.
Causal Role of the Dorsolateral Prefrontal Cortex in Belief Updating under Uncertainty
Authors: Schulreich Stefan , Schwabe Lars 
Published: July 2020

Abstract
Adaptive performance in uncertain environments depends on the ability to continuously update internal beliefs about environmental states. Recent correlative evidence suggests that a frontoparietal network including the dorsolateral prefrontal cortex (dlPFC) supports belief updating under uncertainty, but whether the dlPFC serves a “causal” role in this process is currently not clear. To elucidate its contribution, we leveraged transcranial direct current stimulation (tDCS) over the right dlPFC, while 91 participants performed an incentivized belief-updating task. Participants also underwent a psychosocial stress or control manipulation to investigate the role of stress, which is known to modulate dlPFC functioning. We observed enhanced monetary value updating after anodal tDCS when it was normatively expected from a Bayesian perspective. A model-based analysis indicates that this effect was driven by belief updating. However, we also observed enhanced non-normative value updating, which might have been driven instead by expectancy violation. Enhanced normative and non-normative value updating reflected increased vs. decreased Bayesian rationality, respectively. Furthermore, cortisol increases were associated with enhanced positive, but not with negative, value updating. The present study thereby sheds light on the causal role of the right dlPFC in the remarkable human ability to navigate uncertain environments by continuously updating prior knowledge following new evidence.
Dispersion Pattern of Giant Cicada (Hemiptera: Cicadidae) in a Brazilian Coffee Plantation

Published: July 2020

Abstract
The giant cicada Quesada gigas (Olivier, 1790) (Hemiptera: Cicadidae) is a major pest of coffee plants in Brazil. To ensure the rational management and ecological equilibrium, information about the behavior, dispersion, and reproduction of giant cicada is fundamental. The present work was conducted in an area of 97 ha planted with Coffea arabica L. to investigate adult dispersion as well as mating and oviposition behaviors of Q. gigas. A sound trap was placed at a ‘release point’ used for the attraction, marking, and release of adults in the area. The recapture of insects was performed with the same sound trap positioned at 20 points distributed at 100, 250, 400, and 1,000 m from the release point. The highest recapture rates of Q. gigas were observed at 100 m from the release point, and the lowest recapture rates were observed at 1,000 m. The presence of Eucalyptus plants in the area apparently influenced dispersion, as high recapture rates were observed at the sites close to Eucalyptus plants. One copulation of Q. gigas lasted 41.6 ± 0.43 min, and the period of a single oviposition bout was 30.0 ± 0.20 min. Quesada gigas adult longevity in the field was estimated to be 49 d. Both males and females were observed performing multiple matings.
