DEA Models with Interval Scale Inputs and Outputs
This paper proposes an alternative approach for efficiency analysis when a set of DMUs uses interval scale variables in the productive process. To test the influence of these variables, we present a general approach of deriving DEA models to deal with the variables. We investigate a number of performance measures with unrestricted-in-sign interval and/or interval scale variables.
متن کاملScale models
Scientists have long noted the link between small genome size and high metabolic rates. Bats and birds have the smallest genomes of vertebrates, and flightless birds tend to have bigger genomes than fliers. The genome is typically present in every cell so carrying around a smaller genome suggests you can have smaller cells, researchers have speculated. Smaller cells mean a larger surface-to-vol...
متن کاملEngineering Models to Scale
Developing organisms can regulate and scale patterns to achieve consistent proportions despite immense changes in size. In this issue, Cao et al. build a model system, using engineered E. coli, to understand how regulatory dynamics can produce pattern scaling without the need for a morphogen gradient.

متن کاملIn Tev Scale Gravity Models
Abstract The first results on next-to-leading order QCD corrections to production of two Z bosons in hadronic collisions in the large extra dimension ADD model are presented. Various kinematical distributions are obtained to order αs in QCD by taking into account all the parton level subprocesses. We estimate the impact of the QCD corrections on various observables and find that they are signif...
