    Goldstone Bosons in Josephson Junctions

    Full text link
    For a microscopic model of a Josephson junction the normal coordinates of the two junction Goldstone bosons are constructed and their dynamical spectrum is computed. The explicit dependence on the phase difference of the two superconductors is calculated

    Pengembangan Media Pembelajaran Berbasis Komputer pada Mata Kuliah Pastry di Jurusan Ilmu Kesejahteraan Keluarga Fakultas Pariwisata dan Perhotelan Universitas Negeri Padang

    The aims of this study was to develop a computer-based learning media is valid and practical course on pastry in the ca of IKK FPP UNP. This study uses Research And Development (R & D) is the method used to produce a specific product and test the feasibility of the product. Products produced in the form of computer-based learning media in the Department of IKK FPP UNP. Data collection techniques in this study conducted using questionnaires given to lecturers caterers and questionnaire responses of students to the media developed and analyzed using analysis deskripstif which includes analysis of the validity, and analysis of the practicalities. The results of this study indicate that the validity of computer-based learning media on valid category (0.89). While the practicalities of the test, the lecturer / practitioner gives very practical category (92.7%) and students leave with a very practical category (88.7%). Based on these findings it can be concluded that computer-based learning media is valid and practical to be used as a medium of learning in the subject of Pastry

    Large deviations for ideal quantum systems

    Full text link
    We consider a general d-dimensional quantum system of non-interacting particles, with suitable statistics, in a very large (formally infinite) container. We prove that, in equilibrium, the fluctuations in the density of particles in a subdomain of the container are described by a large deviation function related to the pressure of the system. That is, untypical densities occur with a probability exponentially small in the volume of the subdomain, with the coefficient in the exponent given by the appropriate thermodynamic potential. Furthermore, small fluctuations satisfy the central limit theorem.Comment: 28 pages, LaTeX 2

    Quantum macrostatistical picture of nonequilibrium steady states

    Full text link
    We employ a quantum macrostatistical treatment of irreversible processes to prove that, in nonequilibrium steady states, (a) the hydrodynamical observables execute a generalised Onsager-Machlup process and (b) the spatial correlations of these observables are generically of long range. The key assumptions behind these results are a nonequilibrium version of Onsager's regression hypothesis, together with certain hypotheses of chaoticity and local equilibrium for hydrodynamical fluctuations.Comment: TeX, 13 page

    The SERRATE protein is involved in alternative splicing in <em>Arabidopsis thaliana</em>

    Howalternative splicing (AS) is regulated in plants has not yet been elucidated. Previously, we have shown that the nuclear cap-binding protein complex (AtCBC) is involved in AS in Arabidopsis thaliana. Here we show that both subunits of AtCBC (AtCBP20 and AtCBP80) interact with SERRATE (AtSE), a protein involved in the microRNA biogenesis pathway. Moreover, using a high-resolution reverse transcript-ase-polymerase chain reaction AS system we have found that AtSE influences AS in a similar way to the cap-binding complex (CBC), preferentially affecting selection of 50 splice site of first introns. The AtSE protein acts in cooperation with AtCBC: many changes observed in the mutant lacking the correct SERRATE activity were common to those observed in the cbp mutants. Interestingly, significant changes in AS of some genes were also observed in other mutants of plant microRNA biogenesis pathway, hyl1-2 and dcl1-7, but a majority of them did not cor-respond to the changes observed in the se-1mutant. Thus, the role of SERRATE in AS regulation is distinct from that of HYL1andDCL1, and is similar to the regu-lation of AS in which CBC is involved
