Software breast phantoms are central to the optimization of breast imaging, where in many cases the use of real images would be inefficient - or impossible. Establishing the realism of such phantoms is critical. For this study, patches of simulated breast tissue with different composition - fatty, scattered, heterogenous and dense tissue - were generated using a method based on Perlin noise. The c
Minority shareholdings have been on the regulatory agenda of competition authorities for some time. Recent empirical studies, however, draw attention to a new, thought-provoking theory of harm: common ownership by institutional investors holding small, parallel equity positions in several competing firms within concentrated industries. While critical voices abound, EU and U.S. antitrust agencies c
Due to its low emission and high energy density, iron powder has been proposed as a promising recyclable metal fuel for a future low-carbon society. The comprehensive understanding of combustion behavior of iron particles is crucial for studying fundamental mechanisms, developing suitable combustion technologies, and designing efficient iron powder combustor. In this work, iron particles are combu
The colloidal stability of lipid based cubosomes, aqueous dispersion of inverse bicontinuous cubic phase, can be significantly increased by a stabilizer. The most commonly used stabilizers are non-ionic tri-block copolymers, poloxamers, which adsorb at the lipid-water interface and hence sterically stabilize the dispersion. One of the challenges with these synthetic polymers is the effect on the i
The sharing economy has emerged as a potential way to reduce the environmental impact and costs of using products, whilst increasing their accessibility. However, there is a paucity of literature on its sustainability implications. To help fill this void we provide a first indicative assessment of the potential sustainability implications for the sharing of three product groups in Sweden, namely c
The ongoing COVID-19 pandemic has radically changed the way we live and had an enormous impact on the global healthcare system [ [1]]. Among many restrictions imposed on the societies, the national lockdowns have particularly disrupted the natural social networks and forced citizens to involuntary isolation. As a result, many patients have felt discouraged to visit their doctors, while emergency d
Sweden is a sparsely populated country with significant hydro, bioenergy, and wind resources. Renewable energy sources currently account for more than 50% of total Swedish use and both electricity production and residential heating are virtually fossil-free. Swedish energy policy can be characterized by the perceived conflict between an ambitious climate policy and the competitiveness of the energ
This analysis comprises part of a larger project on the placement of rune-stones in the local area of Tiohärad. It considers two rune-stones, Sm 36 and Sm 37, in Bolmaryd. The older stone, Sm 36, is placed in the grounds of what would have been a large farmhouse or village and could only have been seen by its householders and visitors. The text is short and simply refers to a family relationship. This analysis comprises part of a larger project on the placement of rune-stones in the local area of Tiohärad.

BACKGROUND: The primary aim was to describe patient-reported morbidity from neurogenic bladder and bowel dysfunction in a cohort of children with spina bifida. The secondary aim was to describe the overall surgical burden in these children.METHODS: Children with meningocele or myelomeningocele, born between 2000-2016, and followed by a tertiary spina bifida center were evaluated in a cross-section
In the dawning age of autonomous driving, accurate and robust tracking of vehicles is a quintessential part. This is inextricably linked with the problem of Simultaneous Localisation and Mapping (SLAM), in which one tries to determine the position of a vehicle relative to its surroundings without prior knowledge of them. The more you know about the object you wish to track—through sensors or mecha
In 2020, the IOC proposed a universal methodology for the recording and reporting of data for injury and illness in sport. Para sport is played by individuals with impairment, and they have a unique set of considerations not captured by these recommendations. Therefore, the aim of this addendum to IOC consensus statement was to guide the Para sport researcher through the complexities and nuances t
Researchers have measured superfluid helium’s full dispersion spectrum, explaining discrepancies in previous studies and constraining theories of superfluidity.
γ-CoV2O6 is a quasi-one-dimensional spin-3/2 magnet that possesses two distinct magnetic orders at low temperatures with propagation vectors k1=(½,0,0) and k2=(¼ + δh, δk, - ¼ + δl), respectively. Here we use muon spin relaxation and rotation to reveal the thermodynamics of the magnetic phase separation in this compound. In the paramagnetic (PM) region, short-range correlated spin clusters emerge
By measuring a linear response function directly, such as the dynamic susceptibility, one can understand fundamental material properties. However, a fresh perspective can be offered by studying fluctuations. This can be related back to the dynamic susceptibility through the fluctuation–dissipation theorem, which relates the fluctuations in a system to its response, an alternate route to access the
This chapter argues that most efforts aimed at using women’s positions relative to climate change will be insufficient if not conducted with great care and analytical sensitivity. It shows that mitigation and adaptation measures of climate change often target women, either as untapped resources for combating climate change or as active and powerful participants in adaptation or mitigation efforts.
