ObjectiveConventional two-dimensional ultrasound has been assessed for the non-invasive diagnosis of giant cell arteritis (GCA), but the results are operator dependent, resulting in low sensitivity. Tomographic three-dimensional (3D) ultrasound is a novel technique that enables the objective documentation of vessel geometry. Here, for the first time, its utility is assessed for visualizing tempora

Background and Aims: Ampullary lesions (ALs) of the minor duodenal papilla are extremely rare. Endoscopic papillectomy (EP) is a routinely used treatment for AL of the major duodenal papilla, but the role of EP for minor AL has not been accurately studied. Methods: We identified 20 patients with ALs of minor duodenal papilla in the multicentric database from the Endoscopic Papillectomy vs Surgical

In the mining industry, flotation is a commonly used process to separate valuable minerals from waste rock in a concentrator. The rougher flotation is the first stage of the process and in Boliden AB’s concentrator at Aitik, it consists of two lines of four flotation cells each. In this paper we consider one line and the buffer tank upstream of it. Modeling this process step, and maintaining an up

The role of magnetic fields for the formation of planets is reviewed. Protoplanetary disc turbulence driven by the magnetorotational instability has a huge influence on the early stages of planet formation. Small dust grains are transported both vertically and radially in the disc by turbulent diffusion, counteracting sedimentation to the mid-plane and transporting crystalline material from the ho

We present a tool for modeling conflict situations that enables simulation and testing of situation awareness in shared autonomy, in this case in an autonomous driving scenario. The flexibility of the tool allows definition of new conflict situations, integration with various control and conflict detection systems, as well as customization of Takeover Request (TOR) signals and different means of c

Taffy Twisters (1998) features an extension of the composer's model of articulation.

Many filters such as triple-band filter, multiband filter, UWB filter, and notch band filters have been investigated in recent decades [1]. Bandpass filters with the features of good performance, micro-package, ease of use, and low cost have been the focus of device miniaturization. However, most of these UWB filters with band-notched have been designed by using various slots either in the ground

Understanding, predicting, and controlling the phenotypic consequences of genetic and environmental change is essential to many areas of fundamental and applied biology. In evolutionary biology, the generative process of development is a major source of organismal evolvability that constrains or facilitates adaptive change by shaping the distribution of phenotypic variation that selection can act

Humanity’s ever-growing energy demands require the implementation of more sustainable ways to harvest and store energy. At the same time, the reduction of greenhouse gas emission and thus global warming remains of paramount importance. To this end, solar energy harvesting presents an attractive route towards satisfying these requirements—be that by conversion to thermal energy, electricity or to c

Gröna och artrika utemiljöer främjar barns och ungas välbefinnande och kunskap, bådegenom hälsofördelar kopplade till biologisk mångfald och genom att skapa förutsättningarför lek och lärande om natur och miljöfrågor. Skolgården skulle kunna bidra till allt detta,men är idag i hög grad en outnyttjad plats för biologisk mångfald och klimatanpassningav städer. I denna policy brief presenteras huvuds
