  2. 1. Translation as Linear Transduction : Models and Algorithms for Efficient Learning in Statistical Machine Translation

    Author : Markus Saers; Joakim Nivre; Anna Sågvall Hein; Dekai Wu; Kevin Knight; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; linear transduction; linear transduction grammar; inversion transduction; zipper finite-state automaton; zipper finite-state transducer; formal language theory; formal transduction theory; translation; automatic translation; machine translation; statistical machine translation; Computational linguistics; Datorlingvistik; Language technology; Språkteknologi; Computational Linguistics; Datorlingvistik;

    Abstract : Automatic translation has seen tremendous progress in recent years, mainly thanks to statistical methods applied to large parallel corpora. Transductions represent a principled approach to modeling translation, but existing transduction classes are either not expressive enough to capture structural regularities between natural languages or too complex to support efficient statistical induction on a large scale.

  4. 2. Learning Physics through Transduction : A Social Semiotic Approach

    Author : Trevor Stanton Volkwyn; John Airey; Bor Gregorcic; Cedric Linder; David Brookes; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Introductory physics; transduction; interactive engagement; social semiotics; representational competence; probeware; mathematical tools; 1-D kinematics; coordinate systems; magnetic field; pedagogical affordance; disciplinary affordance; Physics with specialization in Physics Education; Fysik med inriktning mot fysikens didaktik;

    Abstract : This doctoral thesis details the introduction of the theoretical distinction between transformation and transduction to Physics Education Research. Transformation refers to the movement of meaning between semiotic resources within the same semiotic system (e.g. READ MORE

  5. 3. Signal Transduction in Photoreceptor Proteins : Insights From Time-Resolved X-ray Solution Scattering

    Author : Oskar Berntsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Signal transduction; Photoreceptor; Time-resolved X-ray solution scattering; Protein dynamics; Phytochrome; Light-oxygen-voltage; Cryptochrome;

    Abstract : The ability to sense and react to different light conditions is of great importance for many organisms on the face of the earth. Specialized proteins known as photoreceptor proteins provide bacteria, plants and animals with this ability. READ MORE

  6. 4. TRAF6 stimulates TGFβ-induced oncogenic signal transduction in cancer cells

    Author : Shyam Kumar Gudey; Marene Landström; Urban Lendahl; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; c-Jun; invasion; non-Smad; Notch; NICD; oncogenesis; presenilin1; PKCζ; prostate cancer; p21; p38; p300; Snail1; TGFβ; TβRI; TACE; TRAF6; ubiquitination; TGFbeta signal transduction; Pathology; patologi;

    Abstract : Prostate cancer is one of the leading causes of cancer-related deaths in men worldwide, with 10,000 new cases/year diagnosed in Sweden. In this context, there is an urgent need to identify new biomarkers to detect prostate cancer at an initial stage for earlier treatment intervention. READ MORE

  7. 5. Dopamine D2 and D3 receptors. Studies on transduction mechanisms and on the role of a D3 gene polymorphism

    Author : Monika Hellstrand; Göteborgs universitet; []
    Keywords : dopamine; dopamine D2 receptor; dopamine D3 receptor; transduction; CHO cells; partial agonism; inverse agonism; arachidonic acid; prostaglandin E2; cAMP; haloperidol; -3-PPP; PNU-99194A; polymorphism; personality;

    Abstract : The neurotransmitter dopamine has been implicated in the pathophysiology of, e.g., Parkinson s disease and schizophrenia, and dopamine receptor-active compounds are commonly employed therapeutically in these and other disorders. READ MORE
