When writing computer software one is often forced to balance the need for high run-time performance with high programmer productivity. By using a high-level language it is often possible to cut development times, but this typically comes at the cost of reduced run-time performance. Using a lower-level language, programs can be made very efficient but at the cost of increased development time. Re

INTRODUCTION: The use of EVAR for more complex aneurysm anatomy has become more widespread over the past decade. Fenestrated and branched stent grafts for the visceral and iliac segment show promising short- and midterm outcome and these procedures have become routine in many vascular centers. However, at present, such grafts are customized to the individual patient and planning and manufacturing

Anticipatory and predictive models are becoming very important features of robot systems. This thesis investigates some aspects of predictive modeling. Is prediction always a good thing? How important is it to anticipate what will happen in the future? Is it better to anticipate far into the future or to focus on the next few seconds? What are the requirements for predictive models? Predictive mod

BACKGROUND: Prognostic and treatment-predictive biomarkers in primary breast cancer are routinely analyzed in the primary tumor, whereas metastatic tumor cells in lymph node metastases are not characterized. The present study aimed to define the concordance between biomarkers in matched pairs of breast cancers and lymph node metastases and to relate their expression to clinical outcome. METHODS: P

A low phase noise CMOS LC quadrature VCO (QVCO) with a wide frequency range of 3.6-5.6 GHz, designed in a standard 0.18 /spl mu/m process for multi-standard front-ends, is presented. A significant advantage of the topology is the larger oscillation amplitude when compared to other conventional QVCO structures. The QVCO is compared to a double cross-coupled LC-tank differential oscillator, both in

Muscular deficits and functional limitations have been found years after meniscectomy of the knee. The purpose of this randomized controlled trial was to examine the effect of functional exercise training on functional performance and isokinetic thigh muscle strength in middle-aged patients subsequent to meniscectomy for a degenerative tear. Four years after meniscectomy, 45 patients (29 men, 16 w

BACKGROUND: Liver resection is a possibly curative treatment for colorectal cancer (CRC) liver metastases. Preoperative chemotherapy may make initially irresectable tumors resectable. The aim of this study was to compare perioperative course and short-term mortality after liver resection for CRC metastases between patients who were and were not treated with preoperative chemotherapy. METHODS: Pati

The placenta is vital for fetal growth and development. Improvement in ultrasound and magnetic resonance imaging have improved our understanding of placental morphology that can be important as in the case of placental accrete/percreta. Functional imaging is presently mainly performed by the use of Doppler ultrasound and can give information on placental perfusion, which can be vital for clinical

Schumpeter, Dahmén, Schön, Freeman, and other evolutionary scholars have shown that economic transformation and technological change are necessary prerequisites for long-term economic growth. However, for the Swedish case the exact sectoral and regional anatomy of the technology shift taking place since 1978 has not yet been disentangled. In this thesis, a disaggregation of the national process is
