Differential Characteristics of Efficient Frontiers in DEA with Weight Restrictions

The non-differentiability and implicit definition of boundary of production possibility set (PPS) in data envelopment analysis (DEA) are two important difficulties for obtaining directional characteristics, including different elasticity measures and marginal rates of substitution. Also, imposing weight restrictions in DEA models have some shortcomings and misunderstandings. In this paper we ut...

NEW FRONTIERS IN ANGIOGENESIS New Frontiers in Angiogenesis

Frontiers in Neuroendocrinology, 1969

the analyses of kinetic patterns, and the physical-chemical theories of enzyme action are discussed in the first section. The second section is devoted to a detailed kinetic analysis of two substrate reactions under steady state conditions. The methods by which experimental variations of pH and temperature may be coupled with other types of kinetic analyses to yield information on the mechanism...

Frontiers in Trust Management

Information and Communication Technologies (ICT) are becoming increasingly important in the way we organize our lives, our workplaces and our societies. ICT allows people and organisations, that have never interacted with each other in the past, to initiate new and mutually beneficial businesses across the world. This means that personal and business information is increasingly being communicat...

Frontiers in drug discovery

The ‘traditional’ view of drug discovery involves a linear process of identifying and validating a target, generating a lead molecule, optimizing its properties and then proceeding to preclinical and clinical studies. In this scheme, the biologists take the lead in identifying and validating a target. The chemists subsequently look for potent smallmolecule inhibitors, most often through optimiz...
