K-isomers in very neutron-rich nuclei around mass 180

gamma-spectroscopy methods have been used to search for microsecond isomers among the fragmentation products of a 1 GeV/nucleon Pb-208 beam. In particular the population of the known K-pi = 35/2(-) isomer in W-179 has been investigated and several new isomeric decays have been found for neutron rich nuclei in the A approximate to 180-200 mass region. The ground state band of the neutron rich N = 1

The mimesis hierarchy of semiotic development: five stages of intersubjectivity in children

The paper proposes that intersubjectivity develops in children along a progression of five (more or less) distinct stages of semiotic development. The theoretical model within which this is couched is the Mimesis Hierarchy (MH) model (Zlatev & Andrén 2009). As in previous treatments, the MH-model focuses on bodily mimesis, its “precursors” (empathetic perception) and “post-developments” (conve

Mathematical Models and Algorithms for Wireless Network Design and Optimization

Optimization techniques always play an important role in designing high-performance wireless systems. This presented thesis studies a selected set of optimization problems for different kinds of wireless networks, making use of mathematical programming techniques to find optimal solutions and of efficient heuristics to find near-optimal solutions. The basic contribution of the thesis consists in a

Synthetic xylan-binding modules for mapping of pulp fibres and wood sections.

Background The complex carbohydrate composition of natural and refined plant material is not known in detail but a matter that is of both basic and applied importance. Qualitative assessment of complex samples like plant and wood tissues requires the availability of a range of specific probes. Monoclonal antibodies and naturally existing carbohydrate binding modules (CBMs) have been used in the pa

Radiation dose reduction in CT of the brain: can advanced noise filtering compensate for loss of image quality?

Background: Computed tomography (CT) of the brain is performed with high local doses due to high demands on low contrast resolution. Advanced algorithms for noise reduction might be able to preserve critical image information when reducing radiation dose.PurposeTo evaluate the effect of advanced noise filtering on image quality in brain CT acquired with reduced radiation dose. Material and Method

An evaluation of measures for quantifying map information

A real-time map must not contain too much information. Therefore, we need measures of map information that could guideline the selection of data layers and the real-time generalisation process. In this paper we evaluate measures of amount of information and distribution of information. The evaluation is performed by (1) defining measures, (2) implementing the measures, (3) computing the measures f

Initial backdraft experiments

A number of large scale backdraft experiments are decribed in this report. A total of 13 experiments have been carried out. During the experiments have several physical properties such as temperature, pressure, gas concentration have been measured. Example graphs are shown in the report. The experimental apparatus as well as the measurments are described in detail in this report. It is difficult t

Using speculation to enhance javascript performance in web applications

JavaScript lets developers provide client-side interactivity in Web applications, but because it is sequential, it can't take advantage of multicore processors. Thread-level speculation (TLS) addresses this issue by enabling the speculation of JavaScript function calls and thus exploits the parallel performance potential multicore processors provide. The authors implemented TLS in the Squirrelfish

Polymorphism in the oxytocin promoter region in patients with lactase non-persistence is not related to symptoms.

BACKGROUND: Oxytocin and the oxytocin receptor have been demonstrated in the gastrointestinal (GI) tract and have been shown to exert physiological effects on gut motility. The role for oxytocin in the pathophysiology of GI complaints is unknown. The aim of this study was to examine genetic variations or polymorphism of oxytocin (OXT) and its receptor (OXTR) genes in patients with GI complaints wi
