Bokkapitel (refereegranskat)abstract
- This chapter introduces a selection of novel and emerging concepts in ambient pressure X-ray spectroscopies. Technical considerations and first photoemission experiments performed in and above 1 bar pressure are described. Then, X-ray spectroscopy experiments that provide high lateral (microscopy) and depth (X-ray standing-waves) resolution in ambient environments are discussed. The final part of the chapter introduces recent developments in multimodal instrumentation, such as the combination of ambient pressure X-ray Photoelectron Spectroscopy with Infrared spectroscopy and X-ray scattering.

Weighted Colimits of 2-Representations and Star Algebras

Tidskriftsartikel (refereegranskat)abstract
- We apply the theory of weighted bicategorical colimits to study the problem of existence and computation of such colimits of birepresentations of finitary bicategories. The main application of our results is the complete classification of simple transitive birepresentations of a bicategory studied previously by Zimmermann. The classification confirms a conjecture he has made.

Clinicopathological significance of microRNA-31, -143 and -145 expression in colorectal cancer

Tidskriftsartikel (refereegranskat)abstract
- We are just beginning to understand how microRNAs (miRNAs) are involved in tumor-related processes in humans. Applying real-time RT-PCR, we investigated the miR-31, miR-143 and miR-145 expression in 98 primary CRC specimens, along with the corresponding normal mucosa specimens, and analyze the relationship of their expression with clinicopathological features. Our results showed the miR-31 expression was up-regulated in CRC compared to normal mucosa (p = 0.001). Furthermore, miR-31 expression was positively related to advanced TNM stage (p = 0.026) and deeper invasion of tumors (p = 0.024). MiR-145 was down-regulated in both colon (p = 0.001) and rectal (p = 0.012) cancer. MiR-143 was only down-regulated in colon cancer (p = 0.023) but not in rectal cancer (p = 0.351). There was no relationship of miR-143 and miR-145 expression with other clinicopathological features (p > 0.05), except that the miR-145 expression was related to cancer site (p = 0.03). In conclusion, the miR-31 overexpression may be involved in the development and progression of CRC. The miR-143 and miR-145 may play a certain role in the development of colon and/or rectal cancers but not in progression of the disease.

Portable rescue device and a method for locating such a device
- 2007
-
Patent (populärvet., debatt m.m.)abstract
- A portable rescue device and a method for locating, by means of a first rescue device set in a search mode, a second rescue device set in a distress mode. In the method, a distress signal carrying a device identification is received from said second rescue device. A first bearing and a second bearing to the second rescue device are obtained. The first and second bearings are taken from a first and a second position, respectively. A distance between these positions is determined. A current distance and a current bearing to the second rescue device are determined on basis of the first and second bearings and the distance. The current bearing and the current distance are communicated to a user of the first rescue device. The portable rescue device is used for performing the method and for that purpose it includes a first communication unit for distress signal transmission and reception; a compass; a processor; a user interface; and a mode switch for switching between a search mode and a distress signal mode. The first communication device has an antenna structure that provides directional capability.

Insider Status-Membership Involvement Offer Trade Off? The Case of Green Parties and Environmental Organisations
- 2023
-
Ingår i: Political Studies. - : SAGE Publications. - 0032-3217 .- 1467-9248. ; 71:3, s. 695-713
-
Tidskriftsartikel (refereegranskat)abstract
- This article theorises and empirically investigates the membership involvement offer in political parties and interest groups in contemporary democracies, to better understand the potential that these political organisations have in performing the role of transmission belts between citizens and the state. The expectation is that parties and interest groups that become insiders will curtail the participatory opportunities for members in decision-making processes, but that insider parties will offer broader avenues for membership involvement than insider interest groups. We explore these propositions by focusing on two Green parties and two environmental public interest groups in the contrasting institutional settings of Norway and the United Kingdom. Our analysis based on primary case study data indicates that insider green parties maintain more inclusive participatory structures than insider environmental groups. The receipt of state benefits leads to less membership involvement in political organisations, unless the state demands recipients of such benefits to be organised democratically.

Integrating automatic and interactive method for coronary artery segmentation : let PACS workstation think ahead
- 2010
-
Ingår i: International Journal of Computer Assisted Radiology and Surgery. - : Springer Science and Business Media LLC. - 1861-6410 .- 1861-6429. ; 5:3, s. 275-285

Tidskriftsartikel (refereegranskat)abstract
- Purpose: To provide an efficient method to extract useful information from the increasing amount of coronary CTA.Methods: A quantitative coronary CTA analysis tool was built on OsiriX, which integrates both fully automatic and interactive methods for coronary artery extraction. The computational power of an ordinary PC is exploited by running the non-supervised coronary artery segmentation and centerline tracking in the background as soon as the images are received. When the user opens the data, the software provides a real-time interactive analysis environment.Results: The average overlap between the centerline created in our software and the reference standard was 96.0%. The average distance between them was 0.38 mm. The automatic procedure runs for 3-5 min as a single-thread application in background. Interactive processing takes 3 min in average.Conclusion: In preliminary experiments, the software achieved higher efficiency than the former interactive method, and reasonable accuracy compared to manual vessel extraction.
