For symmetric pairings e : G × G → GT , Verheul proved that the existence of an efficiently-computable isomorphism φ : GT → G implies that the Diffie-Hellman problems in G and GT can be efficiently solved. In this paper, we explore the implications of the existence of efficiently-computable isomorphisms φ1 : GT → G1 and φ2 : GT → G2 for asymmetric pairings e : G1 ×G2 → GT . We also give a simpl...

New oxides of the (NdSr)n+1MO3n+1 (M = Co and Mn or Fe) series are reported. Compounds of composition NdSrCo0.75Fe0.25O4.10, NdSrCo0.75Mn0.25O4.08 and Nd0.5Sr1.5Co0.75Mn0.25O3.86 are the n = 1 members of the Ruddlesden-Popper homologous series (K2NiF4 structural type) as determined by X-ray diffraction and different transmission electron microscopy techniques. Their crystal structure consists o...

Our interest in the exchange reaction of oxygen between the gas phase and oxides is twofold: (i) to understand the mechanistic details of one of the "simplest" gas-solid reactions which nevertheless exhibits an astonishing complexity in terms of reaction pathways, (ii) to use this knowledge for improving electrochemical devices which rely critically on a fast oxygen incorporation rate such as c...

Poly(Glu50Tyr50) (GT) is not immunogenic in most inbred mouse strains. GT injection produces an I-J--bearing, GT-specific T-cell--derived suppressor factor (GT-TsF1) in H-2b,d,k haplotype mice. GT-TsF1 generates second-order suppressor T cells (Ts2) in H-2a,d,k haplotype mice. Here, we show that in order for GT-TsF1 to act, the recipient strain must express I-E molecules. This suggests that T c...

In the present studies we have confirmed that the random copolymer of L-glutamic acid50-L-tyrosine50 (GT) fails to induce an antibody response in a large number of inbred strains of mice. Nevertheless, GT complexed to methylated bovine serum albumin (MBSA) elicits a GT-specific IgG PFC response in vivo. Furthermore, injection of BALB/c mice with 10 to 100 mug of GT specifically decreases their ...

Fuel Cell–Gas Turbine (FC-GT) hybrid technology portends a significant breakthrough in electrical generation. Hybrid systems reach unprecedented high efficiencies, above 70% LHV in some instances, with little to no pollution, and great scalability. This work investigates two high temperature fuel cell types with potential for hybrid application ranging from distributed generation to central pla...

BACKGROUND Hepatitis C virus (HCV) genotype (GT) has become an important measure in the diagnosis and monitoring of HCV infection treatment. In the United States (U.S.) HCV GT 1 is reported as the most common infecting GT among chronically infected patients. In Europe, however, recent studies have suggested that the epidemiology of HCV GTs is changing. METHODS We assessed HCV GT distribution ...

This work aims at developing a renewable energy storage solution, based on reversible solid oxide cell (rSOC) technology. Firstly, the initially high performing cells were tested as single with long-term SOFC/SOEC load cycles part of test sequence. Secondly, similar integrated in stack design optimized for operation degrees utilization. The tests showed significant degradation galvanostatic per...

The solid oxide fuel cell (SOFC) is used as secondary source in micro grid application. When the renewable sources are not able meet load requirement, Battery energy back-up system supposed to supply demand. SOFC come into action when state of charge (SOC) battery backup becomes too low. parameters assumed constant during its operation but those operating practically constant. vary widely which...

In the companion paper, the random copolymer of L-glutamic acids°-L-tyrosine" (GTf was shown to be unable to stimulate the formation of specific antibodies in 19 inbred and congenic resistant strains of mice (1). In several of these strains, however, GT complexed to methylated bovine serum albumin (GT-MBSA) was able to stimulate specific plaque-forming cell (PFC) responses . Furthermore, immuni...
