The double-ionization yield of He is calculated with a one-dimensional fully correlated two-electron model for the low laser frequency of recent experiments. Results for a higher laser frequency also indicate a comparable very high double-ionization yield for sufficiently short pulses. It is shown that the Hartree-Fock approximation fails dramatically in describing the two-electron dynamics. Also,
CONTEXT: The risk of breast cancer in BRCA1 and BRCA2 mutation carriers has been examined in many studies, but relatively little attention has been paid to the degree to which the risk may vary among carriers. OBJECTIVES: To determine the extent to which risks for BRCA1 and BRCA2 carriers vary with respect to observable and unobservable characteristics. DESIGN, SETTING, AND PARTICIPANTS: Probands
This paper examines the assumption that the volume of domestic patenting in Vietnam is too low and needs to be expanded. The structure and state of development of the Vietnamese economy and a set of relevant systems - including the Science and Technology (S&T) System, the Intellectual Property System, the National Innovation System (NIS), and the Science, Technology and Innovation (STI) Policy
Popular Abstract in English The aim of this thesis is to investigate the evolution of new technology-based firms (NTBFs) based on solid empirical material for the Swedish economy. The focus on this thesis is exploring the role of acquisition by incumbent firms in the evolution of NTBFs. The findings of this thesis show that selection is a core feature in the evolution of NTBFs. NTBFs experience a The aim of this thesis is to explore the evolution of new technology-based firms (NTBFs) based on solid empirical material for the Swedish economy. NTBFs are argued to be one important type of entrepreneurial firms that contribute to technology change, knowledge spillovers, and economic growth. However, our knowledge concerning how NTBFs exert their technological and economic influences is far fro

This licentiate thesis, containing two papers, is in the field of biomedical signal processing with main focus on signal processing of the ECG in patients with atrial fibrillation (AF). The two papers deal with different aspects of characterization of the f waves during atrial fibrillation. In the fist paper several measures designed to extract features of the f waves are evaluated with respect to
Popular Abstract in Swedish Människors sätt att visualisera objekt bygger på en del underliggande principer som man kanske inte alltid reflekterar över. Det faktum att vi har just två ögon gör det till exempel möjligt för oss att avgöra på vilket avstånd ett objekt befinner sig. Detta kallas för parallaxeffekten. Kameror, som bara har ett "öga", saknar denna förmåga, vilket försvårar avbildande mäLaser sheet imaging, also known as planar laser imaging, is one of the most versatile optical imaging techniques known and is frequently applied in several different domains. It furthermore constitutes the basis for a variety of other 2D methods, in turn allowing visualization of e.g. velocity, particle size, species concentration and temperature. However, when applied on turbid, light scattering
Leucopatch is a leukocyte and platelet-rich fibrin patch that provides concentrated blood cells and signal substances to the surface of an ulcer. It is produced by centrifugation of the patient's own venous blood. The aim of this pilot multicentre cohort study was to evaluate effects of the leucocyte patch in patients with hard-to-heal diabetic foot ulcers (DFUs).
This correspondence investigates the asymptotic behavior of reduced-state ISI equalizers, based on the Ungerboeck and Forney observation models. It is shown that Ungerboeck-based equalizers can suffer from correct-path-loss (CPL) even in the noiseless regime. ISI conditions that lead to CPL are analytically derived and illustrated by examples.
How to make a workplace health promotion questionnaire process applicable, meaningful and sustainable Background In workplace health promotion, a questionnaire could be of great use. Unfortunately, fatigue regarding answering questionnaires has recently become greater than before. An action research approach could be a possible way of increasing employee participation. Aim This study reports an at
I ett examensarbete som nyligen avslutats på Byggnadsmaterial, Chalmers, har man tagit reda på vad aktörerna i byggbranschen vet om fuktdimensionering. I arbetet intervjuades ett flertal konsulter, entreprenörer och beställare om deras syn på fuktfrågor i byggandet.
OBJECTIVE: To develop a simple and robust assay suitable for fetal RHD screening in first-trimester pregnancy and to estimate the sensitivity and specificity of the test after its implementation in an unselected pregnant population. METHODS: Pregnant women attending their first antenatal visit were included, and fetal RHD determination was performed for all women who typed RhD-negative by routine
