    CUORICINO is an array of 62 TeO2 bolometers with a total mass of 40.7 Kg (10.4 Kg of 130Te), the largest operating one for a cryogenic experiment. Organized as a 14 storey tower, it is meant as a slightly modified version of one of the 25 towers of the CUORE project, a proposed tightly packed array of 1000 TeO2 bolometers (750 kg of total mass of TeO2) for ultralow-background searches on neutrinoless double beta decay, cold dark matter, solar axions, and rare nuclear decays. CUORICINO data taking started on April 2003 at the Laboratori Nazionali del Gran Sasso (LNGS) and was stopped in November 2003 to repair the readout wiring system of the 62 bolometers. Detector performance and early background analysis results are reviewed. Preliminary results on ÎČÎČ(0Îœ) of 130Te are presented. The expected performance and sensitivity of CUORE is also discussed

    The Gene Ontology project in 2008

    The Gene Ontology (GO) project (http://www.geneontology.org/) provides a set of structured, controlled vocabularies for community use in annotating genes, gene products and sequences (also see http://www.sequenceontology.org/). The ontologies have been extended and refined for several biological areas, and improvements to the structure of the ontologies have been implemented. To improve the quantity and quality of gene product annotations available from its public repository, the GO Consortium has launched a focused effort to provide comprehensive and detailed annotation of orthologous genes across a number of \u2018reference\u2019 genomes, including human and several key model organisms. Software developments include two releases of the ontology-editing tool OBO-Edit, and improvements to the AmiGO browser interface

    Deep Underground Neutrino Experiment (DUNE), Far Detector Technical Design Report, Volume II: DUNE Physics

    The preponderance of matter over antimatter in the early universe, the dynamics of the supernovae that produced the heavy elements necessary for life, and whether protons eventually decay -- these mysteries at the forefront of particle physics and astrophysics are key to understanding the early evolution of our universe, its current state, and its eventual fate. DUNE is an international world-class experiment dedicated to addressing these questions as it searches for leptonic charge-parity symmetry violation, stands ready to capture supernova neutrino bursts, and seeks to observe nucleon decay as a signature of a grand unified theory underlying the standard model. The DUNE far detector technical design report (TDR) describes the DUNE physics program and the technical designs of the single- and dual-phase DUNE liquid argon TPC far detector modules. Volume II of this TDR, DUNE Physics, describes the array of identified scientific opportunities and key goals. Crucially, we also report our best current understanding of the capability of DUNE to realize these goals, along with the detailed arguments and investigations on which this understanding is based. This TDR volume documents the scientific basis underlying the conception and design of the LBNF/DUNE experimental configurations. As a result, the description of DUNE's experimental capabilities constitutes the bulk of the document. Key linkages between requirements for successful execution of the physics program and primary specifications of the experimental configurations are drawn and summarized. This document also serves a wider purpose as a statement on the scientific potential of DUNE as a central component within a global program of frontier theoretical and experimental particle physics research. Thus, the presentation also aims to serve as a resource for the particle physics community at large
