This paper presents a parametric study of giant planet migration through the combined action of disk torques and planet-planet scattering. The torques exerted on planets during Type II migration in circumstellar disks readily decrease the semi-major axes a, whereas scattering between planets increases the orbital eccentricities ǫ. This paper presents a parametric exploration of the possible par...

Impairments in cell migration processes may cause various diseases, among which cancer cell metastasis, tumor angiogenesis, and the disability of immune cells to infiltrate into tumors are prominent ones. Mathematical modeling has been widely used to analyze the cell migration process. Cell migration is a complicated process and requires statistical methods such as random walk for proper analys...

migration of compounds from packaging materials is one of the most important aspects of food safety. epoxy resins have been in inner coatings of food cans since the 1960s. these resins can be produced from bisphenol-a diglycidyl ether (badge) that is also utilized as a starter. migration of potentially toxic compounds in epoxy resins used for commercial cans is a very important food safety issu...

introduction census data of iran show that about 68.5% (1956) to 29% (2011) of rural population has decreased over the past half-century. rural population has rapidly declined over the last half century and is influenced by several factors, one of which is rural- urban migration. although the percentage of rural to urban migration (20%) and urban to rural one (17%) from 1996 to 2006 show less d...

Migration of legacy assets to SOA embodies a key challenge of service engineering, the rehabilitation of pre-existing enterprise assets into a service based system. As there is still little conceptual characterization of what the legacy to SOA migration process entails it is difficult to understand, compare and assess different approaches. This paper therefore proposes a conceptual framework em...

Live migration enables a running virtual machine to move between two physical hosts with no perceptible interruption in service. This allows customers to avoid costly downtimes associated with hardware maintenance and upgrades, and facilitates automated load-balancing. Consequently, it has become a critical feature of enterprise class virtual infrastructure. In the past, live migration only mov...

The migration of packaging material constituents into food is a product of the interaction between the food and packaging material. This phenomenon is of importance because some migrating substances may be toxicologically carcinogenic and endanger the consumer safety. Polystyrenes are used in many food-contact applications for the packaging of aqueous-based, fatty and dry foods. The correlation...
