Using a birational correspondence between the twistor space of S2n and projective space, we describe, up to birational equivalence, themoduli space of superminimal surfaces in S2n of degree d as curves of degree d in projective space satisfying a certain differential system. Using this approach, we show that the moduli space of linearly full maps is nonempty for sufficiently large degree and we...

Using a connectedness-measurement technology fundamentally grounded in modern network theory, we measure real output connectedness for a set of six developed countries, 1962-2010. We show that global connectedness is sizable and time-varying over the business cycle, and we study the nature of the time variation relative to the ongoing discussion about the changing nature of the global business ...

We determine the dimensional dependence of percolative exponents jamming transition via numerical simulations in four and five spatial dimensions. These novel results complement literature ones, establish as a mixed first-order percolation transition, with critical $\beta =0$, $\gamma = 2$, $\alpha 0$ finite size scaling exponent $\nu^* 2/d$ for values dimension $d \geq 2$. argue that upper is ...

Social connectedness derived from Facebook is associated with positive outcomes such as better psychological health wellbeing. Yet to date, little is known about the construct of Facebook social connectedness. The aim of this study was to draw on existing studies of Facebook use to investigate what might predict social connectedness stemming from Facebook use. Participants (N = 326, age range 1...

Subjective well-being theories of goal approach and value-as-a-moderator were applied to examine the role of importance of social connectedness on the relationship between social connectedness and subjective well-being in a community sample of 204 Korean immigrants. It was hypothesized that social connectedness in ethnic and mainstream society is a stronger predictor of well-being to immigrants...

School connectedness, encompassing positive feelings toward teachers and peers and a sense of belonging at school, has been touted as a critical factor in promoting student achievement and reducing youth risk behaviors. The literature has been mixed in terms of understanding the relationship between race, racial congruence and school diversity’s influence on school connectedness, particularly f...

In this paper, we present an enhancement of the fuzzy connectedness-based image segmentation method based on dynamic computation of adaptive weights for the homogeneity and the directional gradient energy functions. Adaptive weights enhance the performance and robustness of the conventional fuzzy connectedness-based segmentation while decreasing the degree of user interaction. The accuracy of t...

For a space–time, the question whether two causally related points can be joined by means of a causal geodesic has a clear physical meaning. More geometrically, geodesic connectedness ~the possibility of joining any two points by a geodesic of any causal type! is a basic property. Some techniques introduced to study geodesic connectedness are appliable to related problems of physical interest, ...
