Ion trap simulations of quantum fields in an expanding universe

We propose an experiment in which the phonon excitation of ion(s) in a trap, with a trap frequency exponentially modulated at rate kappa, exhibits a thermal spectrum with an Unruh temperature given by k(B)T=h kappa. We discuss the similarities of this experiment to the response of detectors in a de Sitter universe and the usual Unruh effect for uniformly accelerated detectors. We demonstrate a new Unruh effect for detectors that respond to antinormally ordered moments using the ion's first blue sideband transition.

Fast simulation of a quantum phase transition in an ion-trap realizable unitary map

We show that a specific implementation of a unitary map on multiple qubits in an ion trap is physically equivalent to a Hamiltonian evolution that belongs to the same universality class as the transverse Ising Hamiltonian. We suggest experimental signatures, and present numerical simulations for the case of four qubits.

Ion trap transducers for quantum electromechanical oscillators

An enduring challenge for contemporary physics is to experimentally observe and control quantum behavior in macroscopic systems. We show that a single trapped atomic ion could be used to probe the quantum nature of a mesoscopic mechanical oscillator precooled to 4 K, and furthermore, to cool the oscillator with high efficiency to its quantum ground state. The proposed experiment could be performed using currently available technology.

Verprolin cytokinesis function mediated by the Hof one trap domain

In budding yeast, partitioning of the cytoplasm during cytokinesis can proceed via a pathway dependent on the contractile actomyosin ring, as in other eukaryotes, or alternatively via a septum deposition pathway dependent on an SH3 domain protein, Hof1/Cyk2 (the yeast PSTPIP1 ortholog). In dividing yeast cells, Hof1 forms a ring at the bud neck distinct from the actomyosin ring, and this zone is active in septum deposition. We previously showed the yeast Wiskott-Aldrich syndrome protein (WASP)-interacting protein (WIP) ortholog, verprolin/Vrp1/End5, interacts with Hof1 and facilitates Hof1 recruitment to the bud neck. A Vrp1 fragment unable to interact with yeast WASP (Las17/Bee1), localize to the actin cytoskeleton or function in polarization of the cortical actin cytoskeleton nevertheless retains function in Hof1 recruitment and cytokinesis. Here, we show the ability of this Vrp1 fragment to bind the Hof1 SH3 domain via its Hof one trap (HOT) domain is critical for cytokinesis. The Vrp1 HOT domain consists of three tandem proline-rich motifs flanked by serines. Unexpectedly, the Hof 1 SH3 domain itself is not required for cytokinesis and indeed appears to negatively regulate cytokinesis. The Vrp1 HOT domain promotes cytokinesis by binding to the Hof 1 SH3 domain and counteracting its inhibitory effect.

Identification of membrane-bound and secreted proteins from Echinococcus granulosus by signal sequence trap

The signal sequence trap technique was applied to identify genes coding for secreted and membrane bound proteins from Echinococcus granulosus, the etiologic agent of cystic hydatid disease. An E. granulosus protoscolex cDNA library was constructed in the AP-PST vector such that randomly primed cDNAs were fused with a placental alkaline phosphatase reporter gene lacking its endogenous signal peptide. E. granulosus cDNAs encoding a functional signal peptide were selected by their ability to rescue secretion of alkaline phosphatase by COS-7 cells that had been transfected with the cDNA library. Eighteen positive clones were identified and sequenced. Their deduced amino acid sequences showed significant similarity with amino acid transporters, Krebs cycle intermediates transporters, presenilins and vacuolar protein sorter proteins. Other cDNAs encoded secreted proteins without homologues. Three sequences were transcribed antisense to E. granulosus expressed sequence tags. All the mRNAs were expressed in protoscoleces and adult worms, but some of them were not found in oncospheres. The putative E. granulosus secreted and membrane bound proteins identified are likely to play important roles in the metabolism, development and survival in the host and represent potential targets for diagnosis, drugs and vaccines against E. granulosus.
