Given a completely arbitrary surface, whether or not it has bounded curvature, or even whether or not it is complete, there exists an instantaneously complete Ricci flow evolution of that surface that exists for a specific amount of time [GT11]. In the case that the underlying Riemann surface supports a hyperbolic metric, this Ricci flow always exists for all time and converges (after scaling b...

This research considers how preferences for location-specific attributes might constrain migration destination choices. In particular, if, at any given time, most people are consuming their desired location-specific attributes, then unwillingness to give up these attributes may influence the decision to migrate. For those who migrate, these desired attributes might significantly constrain the l...

The monitoring of the Transmission Control Protocol (TCP) state variables can provide an understanding of how various traffic flows on a network interact. As discussed in previous work [1] the rate and diversity of the raw information available is incomprehensible in real time, considering human cognitive processing limitations. In the technical report we will demonstrate a solution to the prob...

We study individual job-separations and their associated destination states for all individuals in the private sector in Denmark for the period 1980 to 1995 and account for the cyclical flows. We find that individual and workplace characteristics as well as business cycle effects are important in explaining the individual behaviour. In policy simulations we look at the impact on individual tran...

A flow is homotopy continuous if it is indefinitely divisible up to S-homotopy. The full subcategory of cofibrant homotopy continuous flows has nice features. Not only it is big enough to contain all dihomotopy types, but also a morphism between them is a weak dihomotopy equivalence if and only if it is invertible up to dihomotopy. Thus, the category of cofibrant homotopy continuous flows provi...

Introduction: This research investigated the effects of violent and football video games on cognitive functions, cortisol levels, and brain waves. Methods: A total of 64 participants competed in a single-elimination tournament. Saliva samples of all players were obtained before and after the games for the assessment of cortisol levels. The cognitive performances of the players were also assess...

cooperation is the foundation of many protocols in wireless networks. without cooperation, the performance of a network significantly decreases. hence, all nodes in traditional networks are required to cooperate with each other. in this paper, instead of traditional networks, a network of rational and autonomous nodes is considered, which means that each node itself can decide whether to cooper...

While game-based learning seems to be an effective instructional approach, the underlying and engagement mechanisms of games are still poorly understood. In current study, we investigated what extent flow experience situational interest different indicators in learning. Fifty-two Finnish 5th graders played a game on fractions at home during COVID-19 enforced distance Flow measures were embedded...
