Updated delegated proof of stake and Nash equilibrium: A mining pool game model for blockchain network

SummaryIn the present era, blockchain technology has an extensive variety of uses in the financial, marketing, and so forth. The performance and security of the blockchain system are directly affected by the consensus algorithm. Since there are 30 consensus techniques like proof of stake, delegated proof of stake, and proof of work, and so forth in the previous years, the operating efficiency, safety, and stability still lag behind the basic requirements. To this concern, this research manuscript introduces a novel consensus mechanism‐based game model using upgraded delegated proof of stake (UDPoS) and Nash equilibrium (NE) that is UDPoS‐NE. In a blockchain network powered by UDPoS, blockchain miners provide computing power to publish blocks. Due to a single miner's limited Computing Power (CP), miners frequently join mining pools and divide the pool's profits in accordance with their respective contributions. However, certain miners launch block‐withholding attacks that lead to loss the computer power and endanger the blockchain network's effectiveness. Therefore, NE is used to calculate cooperative game solutions and optimize policy decisions of the miners to frustrate the block withholding attack by the influence of stakes and computing power on producing blocks. Using this mechanism, efficiency, and stability in the consensus process is achieved through the combined influence of computing resources and stakes on block generation. Finally, the suggested model's applicability and validity are confirmed with a throughput (600 TPS), delay (3 s), and energy consumption (<100 KWh) for 10 nodes and processing time (0.9 s) for 200 nodes.

Health factors that influence sustainable behaviour in a single-player resource management game

Encouraging sustainable use of limited natural, social, and economic resources requires understanding the variety of ways in which people think about how resources work and how they adjust their behaviour (or not) as available resources fluctuate. Previous investigations which have focused on understanding how individuals navigate erodible resources, have tended to use group-based, common pool games. However, such social games make it difficult to disentangle whether resource erosion is linked to difficulty navigating the dynamics of the resource or caused by social factors. Here, in two experiments, we recruited 781 participants to play a single-player resource management game in which individuals were invited to harvest monetary rewards from a fully depletable but stochastically replenishing resource over time. We find that the ability to sustain a resource over successive harvesting opportunities (in order to maximize the total harvested rewards) is reliably worse in individuals reporting elevated psychological distress, the often cooccurring hazardous alcohol use, and elevated rates of delay discounting. The associations between resource outcomes, harmful alcohol use, and psychological distress remained substantial even once we had controlled for elevated discounting rates (as a form of impulsivity and a strong risk factor for these health challenges). By contrast, individuals who reported higher levels of financial literacy and general well-being achieved better resource outcomes. Our observations demonstrate that the capacity to respond effectively to the dynamics of a resource are compromised in individuals at risk of psychological and alcohol-related disorders.

Indoor Pool Game and Substance Abuse as Trajectories to Students' Academic Procrastination: The Mediation Role of Self-Regulation.

BackgroundOver the last decade, indoor pool games (IPGs) and substance abuse (SA) became a remarkable emerging addictive behavior among adolescent university students. With the failure of educational quality and retention of learners, boomerangs around the university local environment in line with the students’ learning culture were not considered in many countries including Ethiopia. Thus, this study aimed to examine the trajectory and contribution of an IPG and SA to students’ academic procrastination (AP) as determinants of quality education.MethodsA sequential explanatory mixed-methods design was employed. Self-reporting questionnaires, interview guides, and an observation checklist were used to collect data. All self-reporting items were adapted from previous scales. By using simple random sampling techniques, 237 undergraduate university students were selected for obtaining the quantitative data, and using purposive sampling, 12 interviewees were selected to collect the qualitative data. The SPSS AMOS version 25 was used to compute the multiple mediation path analysis. The Hayes PROCESS macro model was used. Furthermore, the thematic content analysis method was employed for the qualitative data.ResultsA direct path analysis was established between IPG, SA, and AP. The path analysis model indicated that IPG did not significantly predict AP. Moreover, SA significantly predicted AP. In addition, SR had a partial mediating effect on the relationship between IPG, SA, and AP.ConclusionThe study concluded that IPG and substances available around the university local environment found trajectories to students’ AP, which in turn affects the quality of education.

The perceptual, heart rate and technical-tactical characteristics of 3 × 3 basketball

The aim of this study was to investigate the perceptual, heart rate and technical-tactical characteristics of elite male and female 3 × 3 basketball games. Eleven male and twenty-two female elite basketball players were monitored using heart rate telemetry, Ratings of Perceived Exertion (RPE) and video analysis across three 3 × 3 basketball tournaments. Linear mixed models were performed to determine the influence of round (pool game, quarter-final, semi-final, final, classification game) and sex on all dependent variables (alpha = 0.05). There was no difference between sexes for heart rate variables (p = 0.53 - 0.85). The greatest percentage (56.9 ± 20.1%) of game time was spent in heart rate zone 5 (90-100% peak heart rate). Overall RPE was higher in semi-finals (7.2 ± 1.5, p ≤ 0.001, ES: 1.27) and finals (7.7 ± 1.6 p ≤ 0.001, ES: 1.67) compared to pool games (5.1 ± 1.5). An analysis of the technical-tactical actions revealed that there were less steals in semi-finals (p = 0.01, ES = 0.56) and finals (p = 0.01, ES = 0.71) compared to pool games, with no sex-related differences present (p = 0.06 - 0.97). Players generally spent one minute on the bench for every three minutes on the court, creating a 3:1 work to rest ratio. Physical preparation programs for elite 3 × 3 basketball athletes should include exposure to high-intensity activity in which heart rates ≥80% of peak heart rate are reached for periods of time similar to that experienced during gameplay. A 3:1 work-to-rest ratio may be beneficial during conditioning training for this population.

The Framework of Consensus Equilibria for Mining-Pool Games and Related Stability of Gap Games Behaviors in Blockchain Ecosystems

The goal of this paper is to establish the general framework of consensus equilibria for Mining-Pool Games in Blockchain Ecosystems, and in particular to explain the stable in the sense for the existence of consensus equilibria related to mining gap game’s behaviors by using one new concept called “consensus games (CG)” in Blockchain Ecosystems, here, the Blockchain ecosystem mainly means the economic activities by taking into the account of three types of different factors which are expenses, reward mechanism and mining power for the work on blockschain by applying the key consensus called “Proof of Work” due to Nakamoto in 2008. In order to do so, we first give an outline how the general existence of consensus equilibria for Mining-Pool Games is formulated, and then used to explain the stable for Gap Games for Bitcoin in the sense by the existence of consensus equilibria under the framework of Blockchain consensus, we then establish a general existence result for consensus equilibria of general mining gap games by using the profit functions for miners as the payoffs in game theory. As applications, the general existence results for consensus equilibria of Gap games are established, which not only help us to claim the existence for the general stability for Gap games under the general framework of Blockchain ecosystems, but also allow us to illustrate a number of different phenomenons on the study of mining- pool games with possible impacts due to miners’ gap behaviors with scenarios embedded in Bitcoin economics. Our study on the explanation for the stability of mining gap game for Blockchain ecosystems shows that the concept of consensus equilibria may play a important role for the development of fundamental theory for consensus economics.

Billiard Physics: Motion of a Cue Ball after Hit by a Cue Stick Horizontally

Billiards and pool games provide an excellent medium to discuss several physics principles including Newton’s laws of motion, friction, impulse-momentum theorem, work-energy theorem, kinematics and dynamics of rotational motion, and rolling motion. This paper provides a complete analysis of the motion of a cue ball that is given a sharp impulse, which is parallel to the horizontal surface. The horizontal impulse, in this work, is restricted to be in the plane passing through the ball’s center of mass and the contact point such that it sets the ball in horizontal motion with no sidespin. The motion of the cue ball until it eventually starts to roll without slipping is analyzed for all different impulse points on the surface of the ball. These analyses provide physics instructors a set of exciting examples on the rolling motion.

AN EXPERIMENTAL INVESTIGATION OF COOPERATION IN THE DYNAMIC COMMON POOL GAME

AbstractThis article studies experimentally to what extent subjects can cooperate in a dynamic common pool game, where the stage game changes endogenously. Although efficiency can be supported with strategies that condition on history, the main finding is that it is difficult to cooperate. Even if the incentives to cooperate are large, modal behavior can be rationalized with equilibrium Markov strategies that do not condition on history. The popularity of Markov strategies, however, is decreasing in the incentives to cooperate. The evidence also suggests that strategic uncertainty added by facing stage games that change in time may move play away from efficiency.

The role of research in common pool problems

Significant amounts of public spending are allocated towards research on climate change, but considerable uncertainties remain. We analyze the strategic role of information acquisition and the determinants of investments in information in a common pool game. In the first stage, countries can acquire a signal about their own environmental damages caused by total emissions. Because signals are public, there are information spillovers between countries. In the second stage, the countries decide how much pollution to emit. We show that there can be an inefficiently high amount of investments in information in the non-cooperative equilibrium compared to the cooperative solution if the countries are risk averse and the expected emissions are sufficiently large. In addition, we analyze what happens if the countries cooperate in one of the stages but not in the other. We show numerically that if the emissions are decided non-cooperatively, countries might agree not to acquire any information at all. But if the emissions levels are decided cooperatively, investments in the non-cooperative equilibrium are always too low.

Design of a Brain-Controlled Video Game based on a BCI System

The Computer Brain Interface (BCIs) is a new type of user interface designed to recognize real-time user-specific intentions based on user brain mapping. Gradual advancing technology behind the BCI interface has made it possible to develop gaming applications that use directly brain input instead of well-known traditional control methods. This paper presents the Mental Pool Game, a brain-controlled computer game powered by Unity3D, which uses a commercial BCI device based on a network of electroencephalography (EEG) sensors placed on the scalp capable of creating brain patterns only by capturing conscious thoughts from a user that can be easily reproduced as mental actions to control strength and speed on which the user can project on the white ball to hit any of the eight balls on the pool table. Mental PoolGame, powered by Unity3D, is a platform that provides all tools necessary for a developer to develop three-dimensional games that has been designed so that the end user no longer uses classical commands that depend on the use of well-known peripheral input devices present on any PC, such as a keyboard, mouse and more recently a joystick to control the movement of space in an object in a virtual environment.

Predictive game patterns in World Rugby Sevens Series games using Markov chain analysis

The purpose of this research was to identify game patterns in rugby sevens, and utilise a Markov chain, to detect how scoring plays are likely to develop. Using notational analysis, a total of 5413 phases were coded from 117 Men’s World Rugby Sevens Series games. Results of a Fisher’s exact test identified significant differences between game patterns in pool games and finals games (p < 0.01) and category 1 games (top 4 ranked vs top 4 ranked teams) and category 2 games (all other games) (p < 0.01). Markov chain analysis revealed that some scoring phases were a result of the previous phase actions. These findings met the Markov assumption that the probability of transition to the next state depends only on the current state. Scoring phases that met the Markov assumption tended to relate to transitional plays resulting from turnovers in possession. The findings suggest that rugby sevens teams should incorporate unstructured practise that involving transitioning from defence to attack, attack to defence and structured defence to unstructured defence into their training.

Federation Internationale de Football Association (FIFA) 2014 World Cup Impact on Hospital-Treated Suicide Attempt (Overdose) in Tehran.

Social influences on suicidal behaviors may be important but are less frequently studied than the influences of mental illness, physical illness, and demographic variables. Major international sporting events may have an impact on suicidal behaviors at the national and local level, an effect possibly mediated by gender and age. We examined the association of hospital-treated deliberate self-poisoning episodes (by gender and by age) in Tehran: before, during, and after the 2014 FIFA World Cup held in Brazil, in which the Iranian national team participated and was eliminated after the pool games. We used a time series analysis within an autoregressive integrated moving average model and found a significant increase in hospital-treated deliberate self-poisoning during the 4-week period of the 2014 FIFA World Cup in Brazil in females but a nonsignificant increase in males. A significant increase was also seen in the youngest age group (12-20years), but not in the two older age groups. If the effects of nonsuccess at major international sporting events could be shown to have a potential harmful effect on aggregate local or national rates of suicidal behaviors, the possibility of preventative interventions and preemptive additional service provision could be planned in advance of these events.

A convivência com os avós: um estudo exploratório na perspectiva das crianças

O objetivo do estudo foi estudar a convivência entre avós e netos, na perspectiva das crianças. Trata-se de um estudo exploratório descritivo, com abordagem qualitativa com seis netos e seis avós, respondendo questões sobre o motivo do cuidado, o significado da convivência, local de interação e atividades lúdicas. Os resultados apontam que os motivos que levam os netos a serem cuidados pelos avós foram adoção, gravidez na adolescência e apoio aos filhos. O significado da convivência depende do tipo de cuidado, para os netos que ficam em tempo integral os avós são cuidadores; para os sistemáticos, companheiros e para os esporádicos, divertidos. As atividades lúdicas entre avós e netos de tempo integral tendem a ocorrer em espaços internos, como jogos educativos e eletrônicos, enquanto os avós sistemáticos e esporádicos priorizam brincadeiras em espaços externos, como praia, piscina, parques e jogos esportivos ao ar livre. A principal conclusão do estudo foi que a relação entre avós e netos está baseada no tipo de relacionamento determinado pela frequência de encontros. Esta frequência possibilita não apenas a quantidade das interações como a sua qualidade na convivência.
