Bias and temperature dependence of the 0.7 conductance anomaly in Quantum Point Contacts

The 0.7 (2e^2/h) conductance anomaly is studied in strongly confined, etched GaAs/GaAlAs quantum point contacts, by measuring the differential conductance as a function of source-drain and gate bias as well as a function of temperature. We investigate in detail how, for a given gate voltage, the differential conductance depends on the finite bias voltage and find a so-called self-gating effect, which we correct for. The 0.7 anomaly at zero bias is found to evolve smoothly into a conductance plateau at 0.85 (2e^2/h) at finite bias. Varying the gate voltage the transition between the 1.0 and the 0.85 (2e^2/h) plateaus occurs for definite bias voltages, which defines a gate voltage dependent energy difference $\Delta$. This energy difference is compared with the activation temperature T_a extracted from the experimentally observed activated behavior of the 0.7 anomaly at low bias. We find \Delta = k_B T_a which lends support to the idea that the conductance anomaly is due to transmission through two conduction channels, of which the one with its subband edge \Delta below the chemical potential becomes thermally depopulated as the temperature is increased.Comment: 9 pages (RevTex) with 9 figures (some in low resolution

Observation of a decoupled band in 123 Cs

The methods of in-beam γ -ray spectroscopy have been used to study 123 Cs produced by the 115 In( 12 C, 4 n ) reaction. Five coincident stretched E 2 transitions, previously assigned in the literature to 123 Ba, have been identified as members of a decoupled band in 123 Cs.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/45822/1/10050_2005_Article_BF01422105.pd

Yersinia effectors target mammalian signalling pathways

Animals have an immune system to fight off challenges from both viruses and bacteria. The first line of defence is innate immunity, which is composed of cells that engulf pathogens as well as cells that release potent signalling molecules to activate an inflammatory response and the adaptive immune system. Pathogenic bacteria have evolved a set of weapons, or effectors, to ensure survival in the host. Yersinia spp. use a type III secretion system to translocate these effector proteins, called Yops, into the host. This report outlines how Yops thwart the signalling machinery of the host immune system.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/73466/1/j.1462-5822.2002.00182.x.pd

STATUS OF THE 14GHz JÜLICH ECRIS

Along with the routine operation at the cyclotron a new first plasma stage has been installed on the 14 GHz source, which provides improved performance of the source for the highest charge states. Some results for Ne and Ar are reported
