Finally, when the wave speed is smaller than the threshold, the nonexistence of traveling wave solutions is established by the theory of asymptotic spreading developed by Jin and Zhao [34].
Recent reports demonstrate that determinant spreading develops in a high frequency of subjects with tumor regression responses after this type of immunotherapy and could be valuable for trial monitoring and the design of more effective vaccines.
Gaining a more detailed understanding of the transmission potential of different avian influenza viruses (AIVs) among co-habitating species will enhance our ability to develop accurate models for disease spread, develop control strategies and, in some cases, assess risk of transmission to humans.
Changing lifestyles over the last decades have given rise to a global epidemic of overweight and obesity which has spread from developed to developing countries and from adults to children and adolescents [ 5- 7].
Experts say that it is becoming increasingly likely that the turmoil will spread to developing countries, like China, which have long sustained high oil prices even as developed economies weakened.
Previous technologies such as railways and electricity took decades to spread to developing countries, but IT is advancing in leaps and bounds.
While Internet cafes have sprung up quickly in even small Indian cities, it is in rural areas, where most people live, that computers must spread if developing nations like India are to close the yawning technology gap with rich countries.
As mobile money services spread in developing countries, so will these types of innovations.
This epidemic has spread to developing countries and achieved a widespread global importance (Abubakari et al., 2008; Kain et al., 2002; Raj et al., 2007).
The in-grain orientation spreads develop strongly at first, then tend to saturate at high strains.
