Abstract:
To meet the needs of racing, both drag bike racing and road races, vehicles or motorcycles with conditions still standing are not enough. Therefore, it is necessary to modify certain parts, including modifying the chassis, body, and engine. The three parts are very related. Of the three parts, the most priority is modifying the engine because the engine is the main factor in a vehicle or motorcycle. What is needed in modifying the engine is improving engine performance or maximizing engine performance. In this study, the author chose a four-stroke kharisma motorcycle because the modification d

We compare single- and multi-agent setups, and compare the identified control policies against the well-known mechanism of opposition-control.

At a cyclist drag racing champions greatly affect the speed of the bike, especially on the use of racing bike helmets. If the aerodynamic force from the racing bike helmet is getting smaller than the use of helmets on the bike racing will be more optimal and will affect the rate of the racer. In this study, numerical simulations were used to investigate the magnitude of the drag force that occurs around the surface of the helmet. With CFD software, 4 variations of attack angle 0°, 10°, 20° and 30° and variations of Reynold number 7.14x104, 1.00x105, and 1.16x105 are simulated to determine the

The computer model suggests that the large lateral area of a wheelchair adds considerably to the retarding drag forces at relative wind angles between 0 and 90°.

Abstract:
The escalation of complexity is a commonly cited benefit of coevolutionary systems, but computational simulations generally fail to demonstrate this capacity to a satisfactory degree. We draw on a macroevolutionary theory of escalation to develop a set of criteria for coevolutionary systems to exhibit escalation of strategic complexity. By expanding on a previously developed model of the evolution of memory length for cooperative strategies by Kristian Lindgren, we resolve previously observed limitations on the escalation of memory length by extending operators of evolutionary variation.

Abstract:
A recent study by Aldrich, Ballard, Lerner, and Rohde (2017) examines whether a specific type of money—donations from leadership political action committees—is systematically related to party goals outside of policy influence. Their model is theoretically incomplete, as leadership political action committees donate considerable money to candidates who do not help the party win new seats or maintain ideological cohesion. I account for this behavior by introducing a new conditional predictor: incumbency. When modeled as a triple interaction with party status and ideological fit, incumbency helps

Abstract:
Fusarium wilt of watermelon (Citrullus lanatus), caused by Fusarium oxysporum f. sp. niveum (FON), is a devastating soil-borne disease limiting watermelon production across the world. Although many watermelon cultivars have been bred for resistance to FON races 0 and 1, the only released cultivars that are resistant to FON 2 are nonharvested pollenizers. The lack of FON 2–resistant edible cultivars is thought to be associated with linkage drag and/or preferential inheritance patterns observed when crossing the resistant, wild source (Citrullus amarus), with edible watermelon.

Abstract:
A road cycling sprint can be described as the acceleration which occurs toward the end of competitions in order to reach the finish line in front of other competitors. The ability to sprint in road cycling is important since most races are decided in either a head-to-head, small group, or mass sprint finish. Cycling velocity during sprints is important. Factors influencing cycling velocity include the cyclist’s physiology, biomechanics and application of force, resistive forces caused by the environment, and the interaction between cyclists. To perform well in sprints, road cyclists are requir

Abstract:
It is perhaps no surprise that young people can be sceptical of the drug-related information they receive in school-based health education, health promotion and the media. Significant societal anxiety surrounds young people’s drug consumption, so it is tempting to approach this scepticism as a problem to be solved. In this article, we look closely at a group of young Australian men (n = 25), all of whom hold deeply sceptical views about the drug information they received in schools, social marketing campaigns and public speech generally. We do not approach their scepticism as a problem to be s

Abstract:
In point contact related applications (ball bearings, ball-screws) the minimum and the central film thickness of lubricant have a particular importance. The literature presents various numerical solutions to determine these parameters in the case of elliptical contacts [1-4]. Most of them refer to the fully developed elastohydrodynamic lubrication regime (EHD). Hamrock [5] proposes four different lubrication regimes depending on the size and importance of two physical phenomena that occur in contact: elastic deformation of the bodies in contact under a given load and lubricant viscosity variat

Abstract:
Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a hereditary cerebral small-vessel disease caused by mutations in the NOTCH3 gene. Classical pathogenic mechanisms are associated with cysteine gain or loss, but recent studies suggest that cysteine-sparing mutations might have a potential role as a pathogen. In comparison with CADASIL patients in Western countries, there are several differences in Asian patients: (1) prevalent locus of NOTCH3 mutations (exons 2–6 [particularly exon 4] vs. exon 11), (2) age at symptom onset, (3) prevalence o

Since the early 1990s, the law and development paradigm of “violence against women” (VAW) has framed gender-based violence against girls and women, especially intimate partner violence, as a grave violation of women's fundamental human rights and a major public health problem demanding concerted state action. Although women of all ages, social classes, races, religions, and ethnicities suffer gender-based violence, international law recognizes that VAW affecting indigenous women is compounded by historical and ongoing racial discrimination.

Different flight manoeuvres of males of Calopteryx splendens were analysed by means of slow-motion filming. The wingbeat frequencies of males flying in tandem were higher than those of single flying males. A male exhibited the highest frequencies when carrying a Blue Featherleg tandem over a distance of 20–25 cm. The widest range of variability of values of wingbeat frequencies were recorded in threatening flight, probably due to the simultaneous communicative function of the wings during that behaviour. The upstroke/downstroke ratio of the wings allows to draw conclusions on their aerodynamic

The de facto referendum on Williams’ leadership became a coronation.

The unique engulfment filtration strategy of microphagous rorqual whales has evolved relatively recently (<5 Ma) and exploits extreme predator/prey size ratios to overcome the maneuverability advantages of swarms of small prey, such as krill. Forage fish, in contrast, have been engaged in evolutionary arms races with their predators for more than 100 million years and have performance capabilities that suggest they should easily evade whale-sized predators, yet they are regularly hunted by some species of rorqual whales. To explore this phenomenon, we determined, in a laboratory setting, wh
