Geochronology of impact structures - constraining syn- and post-impact processes using the 40Ar/39Ar and U-Pb techniques

The discovery, at the beginning of the 20th century, that elements can transform into other elements, due to the spontaneous decay of an instable to a stable atomic nuclei, gave rise to a powerful source for age information in many fields of earth science. For impact structures, it is crucial to establish well-defined and precise ages in order to understand how impact events affect the Earth’s geoThe discovery, at the beginning of the 20th century, that elements can transform into other elements, due to the spontaneous decay of an instable to a stable atomic nuclei, gave rise to a powerful source for age information in many fields of earth science.

Model nuclear energy density functionals derived from ab initio calculations

We present the first application of a new approach, proposed in (2016 J. Phys. G: Nucl. Part. Phys. 43 04LT01) to derive coupling constants of the Skyrme energy density functional (EDF) from ab initio Hamiltonian. By perturbing the ab initio Hamiltonian with several functional generators defining the Skyrme EDF, we create a set of metadata that is then used to constrain the coupling constants of t

Strain mapping inside an individual processed vertical nanowire transistor using scanning X-ray nanodiffraction

Semiconductor nanowires in wrapped, gate-all-around transistor geometry are highly favorable for future electronics. The advanced nanodevice processing results in strain due to the deposited dielectric and metal layers surrounding the nanowires, significantly affecting their performance. Therefore, non-destructive nanoscale characterization of complete devices is of utmost importance due to the sm

The interplay between social capital and knowledge contribution in online user communities

Firms have been increasingly relying on online user communities (OUC) to access external, distant knowledge and expertise. Previous research on OUC has largely investigated the influence of individuals' social capital on their knowledge sharing behavior. In this study, we propose a spiral view on the relationship between social capital and knowledge contribution. We suggest that there are two-way

Geographic clustering in evolutionary economic geography

Evolutionary economic geography (EEG) explains the spatial evolution of firms, industries, networks, cities and regions from elementary processes of the entry, growth, decline and exit of firms, and their locational behaviour. In an evolutionary approach to economic geography, one typically reasons from the historical processes that have led to particular spatial patterns such as uneven levels of

Towards a Roadmap for a Resource Efficient and Effective Manufacturing Industry in Sweden

The transition to a resource efficient economy that makes effective use of raw materials and energy is a multi-level dynamic process requiring a wide systems perspective. To operationalize this transition in a holistic manner, the concept of Circular Economy (CE) has been championed by major economies around the world. The idea with CE is to strive towards maximizing the utilization of products, c

Value of information and value of decisions

This paper introduces an extended formulation of decision analyses, which provides an enhanced basis for the definition of the value of information, the value of actions and the value of actions and information analyses. The formulation of decision analyses is (1) extended by introducing an action implementation uncertainty and - following the reasoning of Raiffa and Schlaifer (1961) - (2) by cons

The choice between surgical scrubbing and sterile covering before or after induction of anaesthesia : A prospective study

Background: Day surgery is increasing, and safe and effective logistics are sought. One part of the in-theatre logistics commonly discussed is whether surgical scrub and sterile covering should be done before or after induction of anaesthesia. The aim of the present study was to compare the impact of surgical scrub and sterile covering before vs. after the induction of anaesthesia in male patients

Distribution of chrome-spinel grains across the 3He anomaly of the Tortonian Stage at the Monte dei Corvi section, Italy

The present-day ocean-climate system configuration took shape during the Miocene Epoch. Toward the end of the epoch, in the late Tortonian at ca. 8.5 Ma, there was an exceptional event: collisional disruption of an >150-km-diameter asteroid, which created the Veritas family of asteroids in the asteroid belt. This event increased the flux of interplanetary dust particles rich in 3He to Earth and pr

Ovarian cancer. Biomarkers, surgical outcome and survival.

Ovarian cancer is the eighth most common female cancer worldwide and the most lethal of the gynaecologic malignancies. Around 700 women are diagnosed in Sweden per year. Due to vague symptoms most of the patients are diagnosed with late-stage epithelial ovarian cancer (EOC) and prognosis is poor, with a five-year survival of 49%. However, for early-stage EOC the prognosis is excellent. Biomarkers
