Canada [182] 1) to assess the prevalence and incidence of psychological distress, mental disorders, substance abuse, parasuicide, risky behaviour and quality of life; 2) to examine the links and interactions between individual determinants, neighbourhood ecology and mental health in each neighbourhood; 3) to identify the conditions facilitating the integration of individuals with mental health ...

We assess the relationship between neighbourhood-level deprivation and local greenspace quality in Glasgow, Scotland. There is interest globally inequality within accessibility of urban greenspace. It recognised that social political inequalities can lead to less well-off areas having or lower-quality evaluate by combining socio-economic data with assessment neighbourhood from Google Street Vie...

We search for various things every day – food, information on the Internet or someone’s name in memory. Despite the different nature of these tasks, they all have a common feature – a final goal with an unknown location in a complex environment. This property of the search raises a problem of trade-off between exploration of new opportunities and exploitation of the known information. We used t...

We study the minimum number of weights assigned to the edges of a graph G with no component K2 so that any two adjacent vertices have distinct sets of weights on their incident edges. The best possible upper bound on this parameter is proved.

We show that the number of points with pairwise different sets of neighbors in a graph is O(2) where r is the rank of the adjacency matrix. We also give an example that achieves this bound.

The prevalence of habitual snoring has been extensively explored in paediatric populations. Although exposure to cigarette smoke increases the risk of habitual snoring in a dose-dependent fashion, the potential contribution of air quality to habitual snoring remains unclear. 6000 questionnaires were distributed to 6- to 12-year-old children attending public schools in five distinct neighbourhoo...

Let G be a graph with two non adjacent vertices and G′ the graph constructed from G by adding an edge between them. It is known that the trace of Q′ is 2 plus the trace of Q, where Q and Q′ are the signless Laplacian matrices of G and G′ respectively. So, the sum of the Q′-eigenvalues of G′ is the sum of the the Qeigenvalues of G plus two. It is said that Q-spectral integral variation occurs wh...
