چکیده

We give a non-enumerative proof that the P -positions of the hexad game give the Steiner system S(5, 6, 12). We show that the distributions of nim sums and Welter values of these P -positions have simple and surprising regularities.

Computational Evaluation of Effects of Motivation Reinforcement on Player Retention

We study how virtual incentive mechanisms (such as leaderboards) help motivate players to extend the game playing time. We have designed a multiplayer strategy game, called OilTrader, which is set in a game-theoretic framework of a Minority Game, to verify the effect of motivation reinforcement on the sustainability of game playing process. We have conducted an experiment with 114 players and e...

Player type simulation in gamified applications

Gamification at is current state lacks methods for fast iteration and evaluation of game mechanics and game elements. Using UAREI modelling method to simulate gamified system and evaluate its effects users based on player types. In the experiment a simulated market of agents is used randomized motivation and behavior accounting. User behavior is expressed using mathematical formula and adjusted...

Investigating the Relationship between Player Types and Learning Styles in Gamification Design

An educational gamification is a new approach that has developed hopes to increase the effectiveness of learning. Computer game users are actually players that are categorized according to their personalities and have different learning styles. To achieve maximum performance in designing gamified learning, one can determine the relationship between player types and their learning styles, and th...

A dimeric DNA interface stabilized by stacked A.(G.G.G.G).A hexads and coordinated monovalent cations.

We report on the identification of an A.(G.G.G.G).A hexad pairing alignment which involves recognition of the exposed minor groove of opposing guanines within a G.G.G.G tetrad through sheared G.A mismatch formation. This unexpected hexad pairing alignment was identified for the d(G-G-A-G-G-A-G) sequence in 150 mM Na(+) (or K(+)) cation solution where four symmetry-related strands align into a n...

Unique quadruplex structure and interaction of an RNA aptamer against bovine prion protein

RNA aptamers against bovine prion protein (bPrP) were obtained, most of the obtained aptamers being found to contain the r(GGAGGAGGAGGA) (R12) sequence. Then, it was revealed that R12 binds to both bPrP and its beta-isoform with high affinity. Here, we present the structure of R12. This is the first report on the structure of an RNA aptamer against prion protein. R12 forms an intramolecular par...
