Försvarsförmåga - En begreppsutredning

The concept of defense capability is commonly used in Swedish social debate and within strategically oriented communication from the government and armed forces. However, this concept does not origin from any formally established definition or concept clarification. Instead, its meaning varies, or is implicit, which is unfortunate when this capability needs to be addressed and communicated intelli

Classification of point-of-care ultrasound in breast imaging using deep learning

Early detection of breast cancer is important to reduce morbidity and mortality. Access to breast imaging is limited in low- and middle-income countries compared to high-income countries. This contributes to advance-stage breast cancer presentation with poor survival. Pocket-sized portable ultrasound device, also known as point-of-care ultrasound (POCUS), aided by decision support using deep learn

Ett skattesystem för Sverige i en global värld

Sänk skatten på arbete, inför enhetlig moms och rak kapitalbeskattning. Det föreslår nationalekonomen Åsa Hansson i en ny SNS-rapport. Mycket har förändrats sedan den stora skattereformen 1990–91. Om skattesystemet görs om utifrån dagens förutsättningar kan Sverige få högre tillväxt och sysselsättning, menar hon.

Optimal Multitaper Spectrograms

Multitaper spectrograms have been proposed as a method of improving the spectrogram as a time-frequency representation (TFR). This thesis aimed to investigate both previously used and new methods for combining multitaper spectrograms of a Gaussian signal and a chirp. More specifically, the use of new measures to optimize the weights of a weighted sum of spectrograms was tested and evaluated. The o

Gamma Spectrometry

Gamma spectrometry primarily is used for identification and quantification of gamma-emitting radionuclides present in samples collected from a specific environment. The objective is often to determine, with a certain confidence, whether the activity concentration of the present gamma emitters exceed some reference level: for example, a criterion for the highest level of impurity of gamma emitters

The Swedish version of EMPATHIC-30 translation and initial psychometric evaluation

Background: One way to measure quality of care is by measuring satisfaction of provided care among patients and their families. EMpowerment of PArents in THe Intensive Care 30 (EMPATHIC-30) is a self-reported questionnaire grounded on the principles of FCC aiming to measure parents' satisfaction with paediatric intensive care. There is lack of Swedish questionnaires measuring satisfaction with pae

Ukrainian refugee solidarity mobilization online

According to UNHRC, approximately 5 million refugees fled Ukraine between the 24th of February and the 17th of April 2022. Governments and civil societies all over Europe face a major task of mobilizing resources to address the refugees' welfare needs. This effort is partly dependent upon the mobilization of informal civil society. In this research note, we present preliminary findings on the onli

High resection rates of colorectal liver metastases after standardized follow-up and multimodal management : an outcome study within the COLOFOL trial

Background: Outcome after colorectal liver metastases (CRLM) resection has improved over time, despite increased resection rates. Hence, it's crucial to identify all patients possible to treat with curative intent. The objectives of this study were to map recurrence pattern, treatment strategy and survival depending on treatment and follow-up strategy. Methods: In the COLOFOL-trial, patients with

Effect of magnetic order on longitudinal Tomonaga-Luttinger liquid spin dynamics in weakly coupled spin-1/2 chains

The quantum many-body interactions in one-dimensional spin- 1/2 systems are subject to Tomonaga-Luttinger liquid (TLL) physics, which predict an array of multiparticle excitations that form continua in momentum-energy space. Here we use inelastic neutron spectroscopy to study the TLL spin dynamics in SrCo2V2O8 , a compound which contains weakly coupled spin-1/2 chains of Co atoms, at 0.05 K and in

Windstorm impacts on European forest-related systems: an interdisciplinary perspective

Windstorms are considered the main disturbing abiotic agent in European forests. They affect a multiplicity of forest-related dimensions, such as forest ecology, forest operations, geomorphology, economy, and socio-cultural aspects. Due to the complex dynamics set off by windstorms, the design of post-windstorm forest management should be characterized by an interdisciplinary approach able to addr

Machine Learning

Machine learning, a sub-field of artificial intelligence, is the study of computer algorithms that improve automatically through experience. Although the term was coined in 1959, machine learning builds on questions/methods that were developed earlier in linear algebra, mathematical analysis, optimization, and mathematical statistics. In this chapter we will give a brief overview of machine learni

Interactive effects of rising temperatures and urbanisation on birds across different climate zones : A mechanistic perspective

Climate change and urbanisation are among the most pervasive and rapidly growing threats to biodiversity worldwide. However, their impacts are usually considered in isolation, and interactions are rarely examined. Predicting species' responses to the combined effects of climate change and urbanisation, therefore, represents a pressing challenge in global change biology. Birds are important model t

Waveform Relaxation with Asynchronous Time-integration

We consider Waveform Relaxation (WR) methods for parallel and partitioned time-integration of surface-coupled multiphysics problems. WR allows independent time-discretizations on independent and adaptive time-grids, while maintaining high time-integration orders. Classical WR methods such as Jacobi or Gauss-Seidel WR are typically either parallel or converge quickly.We present a novel parallel WR

Managing barriers to sustainable urban freight systems : exploring the city’s influence on a transition

Urban freight logistics is a growing phenomenon in cities and contributes to the wealth of citizens and businesses in urban areas. But it also has negative side effects such as emissions, congestion, and accidents, which eradicate some of their benefits for society. The current development of urban freight logistic activities is unsustainable. A more sustainable path of development is needed but i
