The exact asymptotic computational complexity for a problem of indexing cells on a uniform grid intersecting with a union of C(1) surfaces has been proven. The computational complexity of the recursive partition indexing algorithm, utilized for simulation of septated tissues, is derived and the algorithm is demonstrated as being asymptotically optimal.

Purpose: To evaluate inter- and intrareader agreement in breast percent density (PD) estimation on clinical digital mammograms and central digital breast tomosynthesis (DBT) projection images. Materials and Methods: This HIPAA-compliant study had institutional review board approval; all patients provided informed consent. Breast PD estimation was performed on the basis of anonymized digital mammog

-An algorithm for displaying gray level images using a small number of flxed quantization levels is proposed. The algorithm, called multilevel halftoning, is based on the Cellular Neural Networks (CNN) paradigm. It tracks the CNN transient outputs and selects the image which is subjectively perceived to be the best when reduced to the allowed number of gray levels. The selection criterion is based

In this article, the concept of the employer is analysed for Swedish conditions from a variety of perspectives. The special difficulties that face the private sector are charted, as are the principles of the legal subject in triparty contracts with temporary employment agencies, platform work, and umbrella companies. Found to go hand in hand with the concept of employee, the concept of the employe

Background: Glenohumeral osteoarthritis can, in the most severe cases, require surgery with insertion of a shoulder arthroplasty. A design with a stem in the humeral bone canal is currently regarded as the standard treatment option in patients who have an intact rotator cuff function, but complications related to the stem including humeral fractures can have devastating consequences. By using a st

This study aims to enhance our understanding of organizational identity work (OIW), building upon previous studies’ emphasis on the usefulness of understanding OIW in terms of storytelling. The paper offers an extended vocabulary for making sense of alternative narration forms. Based on an in-depth study of a humanitarian organization in Sweden, the discursive OIW struggles of employees in times o

Blickens kreativitet står i fokus i doktorsavhandlingen Pippi mellan världar (2020). Här introducerar jag nymaterialistiska tankegångar i en bildretorisk studie. Jag betonar särskilt lyssnarens/betraktarens egen medskapande roll när hon kreativt orienterar sig i sin omvärld. Med exempel hämtade ur svenska och tyska bokutgåvor visar jag hur bokillustrationer och pärmbilder framhäver det lekfullt no

Lately, the idea of ‘non-toxic’ (or ‘clean’) material cycles has become increasingly popular as a starting point for the consideration of circular economy strategies among leading regulating actors, such as the European Commission (2017). However, it should be apparent that, by default, circular economy aspirations awaken a potential policy conflict between increased circulation of resources and r

Objective: Segmentation is one way of improving data protection. The aim of this study was to investigate Information Technology (IT) and Medical Technology (MT) personnel's perception in relation to ongoing segmentation of medical devices and IT infrastructure in the healthcare sector. Methods: Focus group interviews with 9 IT and 9 MT personnel in a county council in southern Sweden were conduct

Land and climate interact in complex ways through changes in forcing and multiple biophysical and biogeochemical feedbacks across different spatial and temporal scales. This chapter assesses climate impacts on land and land impacts on climate, the human contributions to these changes, as well as land-based adaptation and mitigation response options to combat projected climate changes.

Maria Nilsson and John Ward look at the scarabs in the graves of two children in the Thutmoside cemetery at the Gebel el-Silsila site.

Biological visual systems provide excellent examples of robust target detection and tracking mechanisms capable of performing in a wide range of environments. Consequently, they have been sources of inspiration for many artificial vision algorithms. However, testing the robustness of target detection and tracking algorithms is a challenging task due to the diversity of environments for application

Background: Early diagnosis of mild lymphedema and treatment are important to prevent its progress. The tissue dielectric constant (TDC), measuring local tissue water in the skin and upper subcutis, has neither been related to the water displacement method (WDM) nor been used to diagnose mild arm lymphedema in patients at risk. Our aims were to evaluate TDC and WDM in combination with palpation, e
