Forskningsöversikt (refereegranskat)abstract
- Stroke remains the second-leading cause of death and the third-leading cause of death and disability combined (as expressed by disability-adjusted life-years lost – DALYs) in the world. The estimated global cost of stroke is over US$721 billion (0.66% of the global GDP). From 1990 to 2019, the burden (in terms of the absolute number of cases) increased substantially (70.0% increase in incident strokes, 43.0% deaths from stroke, 102.0% prevalent strokes, and 143.0% DALYs), with the bulk of the global stroke burden (86.0% of deaths and 89.0% of DALYs) residing in lower-income and lower-middle-income countries (LMIC). This World Stroke Organisation (WSO) Global Stroke Fact Sheet 2022 provides the most updated information that can be used to inform communication with all internal and external stakeholders; all statistics have been reviewed and approved for use by the WSO Executive Committee as well as leaders from the Global Burden of Disease research group.

- In Europe, around half of all patients diagnosed with cancer are treated with radiation therapy. To reduce waiting times, optimizing the use of linear accelerators for treatment is crucial. This paper introduces an Integer Programming (IP) and two Constraint Programming (CP) models for the non-block radiotherapy patient scheduling problem. Patients are scheduled considering priority, pattern, duration, and start day of their treatment. The models include expected future patient arrivals. Treatment time of the day is included in the models as time windows which enable more realistic objectives and constraints. The models are thoroughly evaluated for multiple different scenarios, altering: planning day, machine availability, arrival rates, patient backlog, and the number of time windows in a day. The results demonstrate that the CP models find feasible solutions earlier, while the IP model reaches optimality considerably faster.

Aristotle’s virtues and how to acquire them
- 2013
-
Ingår i: Virtue Ethics and Human Enhancement. - Dordrecht : Springer Nature. ; , s. 31-42
-
Bokkapitel (refereegranskat)abstract
- Now the turn has come to say more both about which virtues, and capacities, Aristotle had in mind and how agents are expected to acquire them. While the focus in this chapter is on the character virtues as well as the intellectual virtues the discussion also extends to how agents are supposed to instill them and how we become (more) virtuous agents. Consequently, a number of key concepts connected to the virtues, e.g., the Doctrine of the Mean, moral expertise and the process of deliberation, are explained and problematized. In addition to providing a theory background the following is also intended to work as a ‘reference chapter’ that the reader could re-visit while reading other parts of the book.

Corrosion mechanisms for nickel exposed to the atmosphere

Tidskriftsartikel (refereegranskat)abstract
- Physical and chemical information on nickel corrosion layer formation, evolution, morphology, and chemical makeup is organized and presented, together with information on nickel-containing minerals and other crystalline structures that might be expected to be present. The chemical reactions involved in the formation of these constituents during the corrosion process are then surveyed. By far the most abundant of the typical corrosion products are various forms of nickel sulfates, including hydroxysulfates and the mineral retgersite (alpha-NiSO4. 6H(2)O). The presence of these species is shown to be a natural consequence of the thin aqueous layer chemistry involving atmospheric SO2 and SO42- that occurs on nickel in humid environments. Formation pathways for retgersite and gaspeite are shown in schematic diagrams. Comprehensive kinetic simulations of the corrosion processes have begun to provide insight into the corrosion chemistry but-are limited by a shortage of laboratory determinations of the rates of dissolution, precipitation, and transformation of nickel-containing chemical species.

On the design of rate-compatible serially concatenated convolutional codes
- 2007
-
Ingår i: European Transactions on Telecommunications. - : Wiley. - 1541-8251 .- 1124-318X .- 2161-3915. ; 18:5, s. 519-527

Tidskriftsartikel (refereegranskat)abstract
- A powerful class of rate-compatible serially concatenated convolutional codes (SCCCs) has been proposed based on minimising analytical upper bounds on the eff or probability in the error floor region. In this paper, this class of codes is further investigated by combining analytical upper bounds with extrinsic information transfer chart analysis to improve performance in the waterfall region. Following this approach, we construct a family of rate-compatible SCCCs with low complexity and good performance in both the error floor and the waterfall regions over a broad range of code rates. The proposed codes outperform standard SCCCs and have a similar performance as more complex parallel concatenated convolutional codes (PCCCs). The proposed codes perform particularly well for high code rates. Copyright (C) 2007 John Wiley & Sons, Ltd.

- We give a brief survey of a particularly interesting class of codes, called spatially-coupled codes, which are strong candidates for future optical communication systems. We discuss some recent research on this class of codes in the area of optical communications, and summarize some open research problems.

Exploratory assessment of parental physical disease categories as predictors of documented physical child abuse

Tidskriftsartikel (refereegranskat)abstract
- Improved prediction of physical child abuse could aid in developing preventive measures. Parental physical disease has been tested previously as a predictor of documented physical child abuse but in broad categories and with differing results. No prior studies have tested clinically recognizable categories of parental disease in a high-powered dataset. Using Danish registries, data on children and their parents from the years 1997-2018 were used to explore several parental physical disease categories' associations with documented physical child abuse. For each disease category, survival analysis using pseudovalues was applied. When a parent of a child was diagnosed or received medication that qualified for a category, this family and five comparison families not in this disease category were included, creating separate cohorts for each category of disease. Multiple analyses used samples drawn from 2,705,770 children. Estimates were produced for 32 categories of physical diseases. Using Bonferroni-corrected confidence intervals (CIc), ischemic heart disease showed a relative risk (RR) of 1.44 (CIc 1.13-1.84); peripheral artery occlusive disease, RR 1.39 (CIc 1.01-1.90); stroke, RR 1.19 (1.01-1.41); chronic pulmonary disease, RR 1.33 (CIc 1.18-1.51); ulcer/chronic gastritis, RR 1.27 (CIc 1.08-1.49); painful condition, 1.17 (CIc 1.00-1.37); epilepsy, RR 1.24 (CIc 1.00-1.52); and unspecific somatic symptoms, RR 1.37 (CIc 1.21-1.55). Unspecific somatic symptoms were present in 71.87% of families at some point during the study period.Conclusion: Most parental physical disease categories did not show statistically significant associations, but some showed predictive ability. Further research is needed to explore preventive potential.What is Known:center dot Few and broad categories of parental physical disease have been examined as risk factors for severe physical child abuse; no prior study has used several categories as predictors.What is New:center dot Unspecific symptoms, ischemic heart disease, peripheral artery occlusive disease, stroke, chronic pulmonary disease, stomach ulcer/chronic gastritis, painful condition, and epilepsy all showed to be potential predictors, with unspecific symptoms being the most prevalent.
