By using the Double Frontiers Criteria, Hurwicz succeeded to achieve The Most Productive Scale Size of decision making units. This Double frontiers criteria was achieved by using two models of “CCR” in optimistic viewpoint in input form and the “CCR” model in pessimistic viewpoint in input form. In this paper, we intend to find a criteria for Double frontiers of super efficiency by using two mo...

in this paper, it is assumed that the “decision making units“( ) are consist of positive and negative input and output. firstly, the optimistic and pessimistic models have been suggested by using negative data and then units with most productive scale size are measured in optimistic and pessimistic models. these productive values are compared with double frontiers and hurwicz’s criterion to obt...

The purpose of this paper is to develop an output oriented methodology for calculating productivity growth by using Malmquist productivity index (MPI) and two different data envelopment analysis (DEA) views (optimistic and pessimistic) simultaneously, and apply it to five Iranian Commercial Banks over the four time period (2009-2013). Consequently, we have proposed a new approach called the dou...

data envelopment analysis (dea) is a method to measure relative efficiency of a set of decision-making units (dmus) which uses multiple inputs and produces multiple outputs. in the conventional dea, crisp inputs and outputs are fundamentally necessary. but the observed values of inputs and outputs in real-world problems are sometimes imprecise. thus, performance measurement often needs to be do...

Neutrinoless double beta-decay (DBD) is of current interest in high-sensitivity frontiers particle physics. The decay very sensitive to Majorana neutrino masses, CP phases, right-handed weak interactions, and others, which are beyond the standard electroweak model. DBDs actually ultrarare events, thus, DBD experiments with ultrahigh sensitivity required. Critical discussions presented on nuclea...

Stimulants have, in their own ways, played a leading role shaping today’s globalised world. Their world-shaping power stems from double role: as “agents” that stimulate bodies, and things “rouse incite” capital. In this issue of Commodity Frontiers, contributions center on the histories presents some stimulant crops sites processes cultivation, expansion, transformations. Contributors variously...

window analysis is a known technique to evaluate performance during the time periods based on data envelopment analysis. in application of window analysis is assumed that efficient frontier have not changed during the periods in the study. unlike the window analysis, malmquist index tries to identify difference between efficient frontiers and separated them. but the means of different frontier ...

Through antisense-induced single-, double-, and multiexon skipping, we have previously demonstrated restoration of dystrophin expression in Duchenne muscular dystrophy (DMD) patient-derived muscle cells in vitro. In this study we further explored the frontiers of this strategy by using specific combinations of 2'-O-methyl phosphorothioate antisense oligonucleotides (AONs) targeting either one o...
