The stem cell niche provides a supportive microenvironment to maintain adult stem cells in their undifferentiated state. Adhesion between adult stem cells and niche cells or the local basement membrane ensures retention of stem cells in the niche environment. Drosophila male germline stem cells (GSCs) attach to somatic hub cells, a component of their niche, through E-cadherin-mediated adherens ...

In portable specially appointed systems (Manets), there is no altered foundation. A standout amongst the most broadly utilized directing conventions for a specially appointed system is the Ad hoc On Demand Distance Vector steering convention, shortened as AODV. In the customary AODV steering convention, source hub advances RREQ (Route Request) bundle to discover way to the terminus hub. The mod...

In recent years, a number of steering conventions have been put out to increase the robustness, fault tolerance, latency, and dependability Wireless Sensor Networks (WSN).A crucial component is determining WSN's vitality requirements extending its lifespan. The traditional bunch-based directing least transmission- vitality, direct transmission, multi-jump steering, static bunching, transmission...

The existing works considering the flow-based discount factor in the hub and spoke problems, assume that increasing the amount of flow passing through each edge of network continuously decreases the unit flow transportation cost. Although a higher volume of flow allows for using wider links and consequently cheaper transportation, but the unit of flow enjoys more discounts, quite like replacing...

In this paper we extend the cultural framework previously developed for the Village multi-agent simulation in Swarm to include the emergence of a hub network from two base networks. The first base network is kinship, over which generalized reciprocal exchange is defined, and the second is the economic network where agents carry out balanced reciprocal exchange. Agents, or households, are able t...

We present the UK Robotics and Artificial Intelligence Hub for Offshore Robotics for Certification of Assets (ORCAHub), a 3.5 year EPSRC funded, multi-site project. The ORCA Hub vision is to use teams of robots and autonomous intelligent systems (AIS) to work on offshore energy platforms to enable cheaper, safer and more efficient working practices. The ORCA Hub will research, integrate, valida...

Hub networks have always been acriticalissue in locating health facilities. Recently, a study has been investigated by Cocking et al. (2006)in Nouna health district in Burkina Faso, Africa, with a population of approximately 275,000 people living in 290 villages served by 23 health facilities. The travel times of the population to health services become extremely high during the rainy season, s...

The Paris Agreement points out that countries need to shift away from the existing fossil-fuel-based energy system to limit the average temperature rise to 1.5 or 2 ◦C. A cost-optimal 100% renewable energy based system is simulated for East Asia for the year 2030, covering demand by power, desalination, and industrial gas sectors on an hourly basis for an entire year. East Asia was divided into...
