In order to assemble the sequence, addition of each nucleoside requires four chemical reaction steps and each of these reaction steps is expected to be quantitative (100%). In reality, efficiencies of these reaction steps vary from 97 to 99.9% depending on the reagents, nucleoside building blocks (phosphoramidite) and moisture in the solvent. Depending on the efficiency of each nucleoside addit...

In this paper, performance analysis of a hybrid photovoltaic-thermal (PV/T) greenhouse air heater and dryer has been carried out. Analytical expressions have been developed for • greenhouse air temperature, instantaneous and overall energy and exergy efficiencies for without load and • instantaneous exergy efficiency with load under forced mode operation. An experimental validation has been car...

This paper provides a description of a novel network layer protocol for underwater acoustic networking (UAN) that provides a mechanism for network control and management enabling the implementation of responsive, self-configuring, adaptable, and scalable networks whose performance are predictable. The protocol draws from the demonstrated efficiencies of multi-protocol labeled switching, dynamic...

We have experimentally verified that the emission of visible light from dye doped polymers can be enhanced with the use of surface plasmon coupling. By matching the plasmon frequency of a thin unpatterned silver film to the emission of a dye doped polymer deposited onto this metal surface, we have observed a eleven-fold enhancement of light emission. By patterning the silver layer, we estimate ...

This paper describes the definition of maximum likelihood equivalent estimators of the Trilinear Gauge Couplings which include detector effects. The asymptotic properties of these estimators as well as their unbiasedness and efficiency when dealing with finite statistical samples are demonstrated by Monte Carlo experimentation, using simulated events corresponding to the reaction e+e− → qq̄lν at...

This article examines the valuable role of group purchasing organizations (GPOs) in hospital purchasing in the United States. For over 100 years old GPOs have helped hospitals and other health care providers realize savings and create contracting efficiencies by aggregating purchasing volume to negotiate discounts with manufacturers, distributors and other vendors. The US has recently enacted a...

Nanostructured phase-separated blends, or bulk heterojunctions, of conjugated polymers and fullerene derivatives form a very attractive approach to large-area, solid-state organic solar cells.The key feature of these cells is that they combine easy processing from solution on a variety of substrates with good performance. Efficiencies of up to 5% in solar light have been achieved, and lifetimes...

Discovery limits for the neutral SUSY Higgses in the l + jet + Emiss t final state from A;H; h ! are calculated as a function of mA and tan . For the selection efficiencies and jet rejection factors results obtained from a detailed simulation of the CMS calorimeter are used. Possibility to suppress the irreducible Z; ! background with b-tagging in the associated production channels is studied. ...

In this study, an analysis of energy and exergy utilization in the utility sector of Jordan by considering the sectoral energy and exergy flows for the years 2007-2011 has been conducted based on real data obtained from main generators in Jordan. The overall energy and exergy efficiencies, for the entire utility sector, are found to be in the range of 35.1 to 38.1%. It is expected that the resu...

Strong electron-electron interactions in graphene are expected to result in multiple-excitation generation by the absorption of a single photon. We show that the impact of carrier multiplication on photocurrent response is enhanced by very inefficient electron cooling, resulting in an abundance of hot carriers. The hot-carrier-mediated energy transport dominates the photoresponse and manifests ...
