    Abstract : This thesis presents HELIOS, an in-house laboratory for time-resolved pump-probe spectroscopy with extreme-ultraviolet (XUV) probe radiation. A wide span of pump wavelengths can be generated using commercial laser equipment while XUV probe radiation is generated via a high harmonic generation process in a noble gas delivering probe photons with energies between 20 eV and 72 eV.

  4. 2. Short Proofs May Be Spacious : Understanding Space in Resolution

    Author : Jakob Nordström; Johan Håstad; Albert Atserias; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Proof complexity; resolution; space; length; width; separation; lower bound; pebble game; pebbling formula; Beviskomplexitet; resolution; minne; längd; bredd; separation; undre gräns; pebblingspel; pebblingformel; Theoretical computer science; Teoretisk datalogi;

    Abstract : Om man ser på de bästa nu kända algoritmerna för att avgöra satisfierbarhet hos logiska formler så är de allra flesta baserade på den så kallade DPLL-metoden utökad med klausulinlärning. De två viktigaste gränssättande faktorerna för sådana algoritmer är hur mycket tid och minne de använder, och att förstå sig på detta är därför en fråga som har stor praktisk betydelse. READ MORE

  5. 3. Parks, Policies and People : Nature Conservation Governance in Post-Socialist EU Countries

    Author : Natalya Yakusheva; Björn Hassler; Magnus Boström; Annica Kronsell; Stacy Vandeveer; Södertörns högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; national parks; Carpathians; Poland; Slovakia; Europeanization; Central Eastern Europe; multi-level governance; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Abstract : The national parks in the Carpathian Mountains along the Polish and Slovak border represent encompassing policy agendas that strive to balance biodiversity conservation and social welfare tasks. These countries have, during the last 25 years, undergone rapid transformation from socialist regimes to liberal democracies, and this transformation has affected the political, social and economic spheres.

  6. 4. Deposition and Resolution of AA Amyloid

    Author : Sofia N. Nyström; Gunilla T Westermark; Christoph Röcken; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; AA-amyloid; autophagy; resolution; Morphology; cell biology; pathology; Morfologi; cellbiologi; patologi;

    Abstract : Amyloidosis is a group of protein misfolding diseases characterized by extracellulardeposition of fibrillar protein aggregates. Today more than 25 different human amyloidogenicproteins have been identified, causing a variety of pathological conditions that includeAlzheimer’s disease, type 2 diabetes and prion diseases.

  7. 5. Optimistic Replication with Forward Conflict Resolution in Distributed Real-Time Databases

    Author : Sanny Syberfeldt; Sten Andler; Jörgen Hansson; Sang H. Son; Alejandro Buchmann; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Distributed Systems; Real-Time Systems; Databases; Replication; Optimistic Protocol; Conflict Resolution; Computer science; Datalogi; Teknik;

    Abstract : In this thesis a replication protocol - PRiDe - is presented, which supports optimistic replication in distributed real-time databases with deterministic detection and forward resolution of transaction conflicts. The protocol is designed to emphasize node autonomy, allowing individual applications to proceed without being affected by distributed operation. READ MORE
