Background and objective: Field invasion games, such as rugby union, can be conceptualised as dynamic social systems in which the agents continuously interact to contest ball possession and territorial gain. Accordingly, this study aimed to identify the collective system dynamics of rugby union phases-of-play near the try line by investigating whether ball displacement trajectory on the playing field provides insights on successful team performance. Methods: Five rugby union matches were videotaped involving teams at a national league performance level. From these matches, 22 second phases-of-play were selected and digitized for analysis. The variable “distance gained” was investigated as a potential coordination variable describing functional coordination between players and teams. This variable concerned the distance between ball initial position and ball current position over time and was used to define the degree of territory gained by an attacking team. Results: Analysis of distance gained dynamics in attacking sub-phases demonstrated the intermittent character of rugby union performers displacement trajectories on the playing field. Amplitude of ball movements was revealed as a distinguishing feature related to attacking effectiveness. Successful attacking phases displayed lower distances of positional retreat...

Cognitive scientists have long been interested in the role that eye gaze plays in social interactions. Previous research suggests that gaze acts as a signaling mechanism and can be used to control turn-taking behaviour. However, early research on this topic employed methods of analysis that aggregated gaze information across an entire trial (or trials), which masks any temporal dynamics that may exist in social interactions. More recently, attempts have been made to understand the temporal characteristics of social gaze but little research has been conducted in a natural setting with two interacting participants. The present study combines a temporally sensitive analysis technique with modern eye tracking technology to 1) validate the overall results from earlier aggregated analyses and 2) provide insight into the specific moment-to-moment temporal characteristics of turn-taking behaviour in a natural setting. Dyads played two social guessing games (20 Questions and Heads Up) while their eyes were tracked. Our general results are in line with past aggregated data, and using cross-correlational analysis on the specific gaze and speech signals of both participants we found that 1) speakers end their turn with direct gaze at the listener and 2) the listener in turn begins to speak with averted gaze. Convergent with theoretical models of social interaction...

Black and white photograph of Rice University Owls track and field athlete Dave Roberts, headlining his achievement into the Rice Athletic Hall of Fame.; Caption reads: Qualified observers of the world of sports have contended over the years the most demanding activity of all sports is the pole vault. The athlete who sets a world record in this severe test of speed, strength, agility and discipline can claim to be one of the finest athletes in the world. Rice University is proud that not one, but two holders of the world record in the pole vault were former Owls – Fred Hansen in the 1960’s and Dave Roberts in the 1970’s. Now Dr. Roberts joins the elite Owl athletes named to the Rice Athletic Hall of Fame. His qualifications are obvious. Dave set the world record of 18-8¼ in 1976 at the U.S. Olympic Trials in Oregon that stood as the world mark for four years. He is the only man in history to win the pole vault title outright in NCAA competition for all three varsity seasons. Dave’s last title was highly dramatic. In 1973 at Baton Rouge, where L.S.U. hosted the event, Roberts sustained an injury in Friday prelims. His last chance on a third try and it was all on the line for the title or to finish down in the field. He made it. Roberts won the National AAU title with his first 18-foot vault. He won the Trials as a graduate in 1976...

The purpose of the present study was to analyze the attacking tasks and tactical organization of elite Women’s Water Polo. The sample consisted of 442 attack sequences of 8 games played by the top teams in a European Championship. Seventeen variables were analyzed according to the position and player’s participation, tactical organization and playing styles, as well as the efficacy of actions performed. The results from this study indicate that positional attack was the predominant performance factor in the attacking process. To this occurrence, the mixed floating defense was identified as the most frequent opposition. The counter-attack proved to be the most efficient strategy. The attacking process frequently started by ball recovering, in anticipation, and by the defense of the goal-keeper in the 2m zone. In central path, a first long-range pass to the right wing predominated. Teams preferred spontaneous shot on goal supported by assisted displacements, and extra player man offence situations. In general, the attacking sequences, do not take longer than 35s to be developed.) Teams efficiency emerged related to the tactical means adopted, namely the spontaneous shot at goal on the front line and numerical superiority of players in attacking game situations.; No presente estudo procedeu-se à caracterização da organização do processo ofensivo em Pólo Aquático feminino de elite a partir da observação de 442 sequências ofensivas de 8 jogos realizadas pelas principais equipas participantes num Campeonato Europeu.

Consider a periodical (in two independent directions) tiling of the plane with polygons (faces). In this article we shall only give examples using squares, regular hexagons, equilateral triangles and parallelograms ("unions" of two equilateral triangles). We shall call some "multiple" of the fundamental region "the board". We naturally identify pairs of corresponding edges of the the board. Figures 9 and 19-29, in this article, show different boards. The "border" of the board is represented by a yellow thick line, unless part of it or all of it is the edge of a face. The board is tiled by a finite number of polygons. Construct polygonal plates in the same number, shape and size as the polygons of the board. Adjacent to each side of each plate draw a number, or two numbers, like it is shown in Figures 1 and 18-29. Figure 1 shows the obvious possibility of having plates with simple drawings, coloured drawings, etc. Now the game is to put the plates over the board polygons in such a way that the numbers near each board edge are equal. If there is at least one solution of this puzzle one says that we have a periodical plane puzzle with numbers. These puzzles are a tool in teaching and learning mathematics. For those that already have some mathematical knowledge...

Multimedia documents such as text, images, sounds or videos elicit emotional responses of different polarity and intensity in exposed human subjects. These stimuli are stored in affective multimedia databases. The problem of emotion processing is an important issue in Human-Computer Interaction and different interdisciplinary studies particularly those related to psychology and neuroscience. Accurate prediction of users' attention and emotion has many practical applications such as the development of affective computer interfaces, multifaceted search engines, video-on-demand, Internet communication and video games. To this regard we present results of a study with N=10 participants to investigate the capability of standardized affective multimedia databases in stimulation of emotion. Each participant was exposed to picture and video stimuli with previously determined semantics and emotion. During exposure participants' physiological signals were recorded and estimated for emotion in an off-line analysis. Participants reported their emotion states after each exposure session. The a posteriori and a priori emotion values were compared. The experiment showed, among other reported results, that carefully designed video sequences induce a stronger and more accurate emotional reaction than pictures. Individual participants' differences greatly influence the intensity and polarity of experienced emotion.; Comment: 5 pages...

The subspace approximation problem Subspace($k$,$p$) asks for a $k$-dimensional linear subspace that fits a given set of points optimally, where the error for fitting is a generalization of the least squares fit and uses the $\ell_{p}$ norm instead. Most of the previous work on subspace approximation has focused on small or constant $k$ and $p$, using coresets and sampling techniques from computational geometry. In this paper, extending another line of work based on convex relaxation and rounding, we give a polynomial time algorithm, \emph{for any $k$ and any $p \geq 2$}, with the approximation guarantee roughly $\gamma_{p} \sqrt{2 - \frac{1}{n-k}}$, where $\gamma_{p}$ is the $p$-th moment of a standard normal random variable N(0,1). We show that the convex relaxation we use has an integrality gap (or "rank gap") of $\gamma_{p} (1 - \epsilon)$, for any constant $\epsilon > 0$. Finally, we show that assuming the Unique Games Conjecture, the subspace approximation problem is hard to approximate within a factor better than $\gamma_{p} (1 - \epsilon)$, for any constant $\epsilon > 0$.

For current state-of-the-art DPLL SAT-solvers the two main bottlenecks are the amounts of time and memory used. In proof complexity, these resources correspond to the length and space of resolution proofs. There has been a long line of research investigating these proof complexity measures, but while strong results have been established for length, our understanding of space and how it relates to length has remained quite poor. In particular, the question whether resolution proofs can be optimized for length and space simultaneously, or whether there are trade-offs between these two measures, has remained essentially open. In this paper, we remedy this situation by proving a host of length-space trade-off results for resolution. Our collection of trade-offs cover almost the whole range of values for the space complexity of formulas, and most of the trade-offs are superpolynomial or even exponential and essentially tight. Using similar techniques, we show that these trade-offs in fact extend to the exponentially stronger k-DNF resolution proof systems, which operate with formulas in disjunctive normal form with terms of bounded arity k. We also answer the open question whether the k-DNF resolution systems form a strict hierarchy with respect to space in the affirmative. Our key technical contribution is the following...

Mobile Communication marketplace has stressed that "content is king" ever since the initial footsteps for Next Generation Networks like 3G, 3GPP, IP Multimedia subsystem (IMS) services. However, many carriers and content providers have struggled to drive revenue for content services, primarily due to current limitations of certain types of desirable content offerings, simplistic billing models, and the inability to support flexible pricing, charging and settlement. Unlike wire line carriers, wireless carriers have a limit to the volume of traffic they can carry, bounded by the finite wireless spectrum. Event based services like calling, conferencing etc., only perceive charge per event, while the Content based charging system attracts Mobile Network Operators (MNOs) to maximize service delivery to customer and achieve best ARPU. With the Next Generation Networks, the number of data related services that can be offered, is increased significantly. The wireless carrier will be able to move from offering wireless telecommunications services to offering wireless telecommunication services plus a number of personalized Value Added Services like news, games, video broadcasts, or multimedia messaging service (MMS) through the network. The next generation Content Based Billing systems allow the operators to maximize their revenues from such services. These systems will enable operators to offer and bill for application-based and content-based services...

## Stability and Chaos in a Multi-Market Oligopoly with Economies of Scale

In an oligopolistic setting under a Cournot scheme, the strategy of each economic player depends on its own quantity decision, but also on its rivals' reaction. Since Puu's seminal work, different oligopoly games have been studied in terms of their stability, as nonlinear discrete time varying systems. Most works in this line of research have concentrated on single markets with linear production structures (i.e. assuming constant returns to scale). Nevertheless, oligopolistic competition seems today to present multi-market phenomena, exhibiting, in some cases, important economies of scale, especially in the retail and service industry. In this paper, we study the stability of a multi-market Cournot-Nash equilibrium with global economies of scale. In other words, we look at the scale level that is related to the total production of firms, in all markets, as opposed to local economies of scale presented at each store individually. The modeling confirms the fact that economies and diseconomies of scale make the Cournot equilibrium very unstable for certain values of the scale of the producers. On the other hand, stability is achieved when the firm reaches absolute advantage with respect to its competition.; Comment: 16 pages, 7 figures
