We present a link–rewiring mechanism to produce surrogates of a network where both the degree distribution and the rich–club connectivity are preserved. We consider three real networks, the AS–Internet, the protein interaction and the scientific collaboration. We show that for a given degree distribution, the rich–club connectivity is sensitive to the degree–degree correlation, and on the other...

Modeling club structures as bipartite networks, we formulate the problem of club formation as a game of network formation and identify those club networks that are stable if agents behave farsightedly in choosing their club memberships. Using the farsighted core as our stability notion, we show that if agents’ payoffs are single-peaked and agents agree on the peak club size (i.e., agents agree ...

Ignacio Vives Ponseti developed a noninvasive method for treating congenital club foot in the US during the late 1940s. Congenital club foot is a deformity that affects the tissues in the lower leg and foot such that the foot abnormally turns inwards and upwards. Ponseti developed the method after noting that an affected infant's tissues are malleable and could respond to gentle correction inst...

'Club drugs' which include Ecstasy, gamma-hydroxybutyrate (GHB), ketamine, and Rohypnol (flunitrazepam) have become popular with participants in 'raves', because they are perceived to enhance energy, endurance, sociability and sexual arousal. These drugs vary in their pharmacologic properties, physiological and psychological effects, and potential consequences. The use of club drugs by young pe...

Club cells (Clara cells) participate in bronchiolar wound repair and regeneration. Located in the bronchioles, they become activated during alveolar injury in idiopathic pulmonary fibrosis (IPF) and migrate into the affected alveoli, a process called alveolar bronchiolisation. The purpose of this migration and the role of club cells in alveolar wound repair is controversial. This study was unde...

Cerebral small vessel disease (SVD) is an important cause of vascular cognitive impairment. Recent studies have demonstrated that structural connectivity of brain networks in SVD is disrupted. However, little is known about the extent and location of the reduced connectivity in SVD. Here they investigate the rich club organisation-a set of highly connected and interconnected regions-and investi...

We study a system where a service is shared by many identical customers; the service is provided by a single resource. As expected each customer experiences congestion, a negative externality, from the others’ usage of the shared resource in our model. In addition, we assume each customer experiences a positive externality from others’ usage; this is in contrast to prior literature that assumes...
