Background and purpose — Radiostereometry (RSA) is the current gold standard for evaluating early implant migration. CT-based migration analysis is a promising method, with fewer handling requirements compared with RSA and no need for implanted bone-markers. We aimed to evaluate agreement between a new artificial intelligence (AI)-based CT-RSA and model-based RSA (MBRSA) in measuring migration of

What constraints and conditions are conducive to the innovation of more advanced watercraft technology? This paper explores this question by modeling ancient voyages in the Channel Island region of southern California. The Chumash and Tongva cultures of this region invented an advanced form of boat, the sewn plank canoe, around 500 CE. This new technology led to a rapid increase in maritime travel

This chapter addresses artistic research through the concept of co-costuming in public—a material-discursive practice between humans and more-than-human materialities with co-creational potentials. The chapter documents how co-costumed entanglements cultivate the wearers’ sociomaterial relation-spatial sensitivity towards each other as well as towards other humans and more-than-human materialities

India and Pakistan are entrenched in an antagonistic relation that is constantly on the verge of, once more, developing into an armed conflict. There are, presently, no signs of conciliatory initiatives on the level of state-to-state interactions, which, contrariwise, tend to uphold incompatible conceptions of regional order, nationhood and the Partition as a constitutive moment. The latter furthe

In this paper, we study rational Collet–Eckmann maps for which the Julia set is not the whole sphere and for which the critical points are recurrent at a slow rate. In families where the orders of the critical points are fixed, we prove that such maps are Lebesgue density points of hyperbolic maps. In particular, if all critical points are simple, these maps are Lebesgue density points of hyperbol

The European Parliament voted against a proposal to curb the use of agricultural pesticides in November 2023. These chemicals, designed to protect crop yield from pest insects and other organisms, can contaminate the water and air and threaten the people and wildlife that maintain the vitality of our landscapes.In some respects, Europe and its governing bodies lead the world in setting and achievi

Variable selection properties of procedures utilizing penalized-likelihood estimates is a central topic in the study of high-dimensional linear regression problems. Existing literature emphasizes the quality of ranking of the variables by such procedures as reflected in the receiver operating characteristic curve or in prediction performance. Specifically, recent works have harnessed modern theory
