This case report presents a clinical, radiographic, and histologic evaluation of 2 non-adjacent, hydroxyapatite-coated, root-form implants retrieved from the maxillary canine area of a patient after 7 years in function. Clinical examination revealed immobile implants with no sign of pathosis. Radiographic examination indicated close proximity of the bone to the implant surface without evidence ...

PURPOSE There is no long-term evaluation on the safety of coronectomy of the lower third molar. The aim of this study was to investigate the 3-year morbidity of coronectomy of the lower third molars and to monitor the behavior and migration pattern of the retained roots after coronectomy. MATERIALS AND METHODS This was a prospective cohort study. Patients with lower third molars with specific...

Consider observation data, comprised of n observation vectors with values on a set of attributes. This gives us n points in attribute space. Having data structured as a tree, implied by having our observations embedded in an ultrametric topology, offers great advantage for proximity searching. If we have preprocessed data through such an embedding, then an observation’s nearest neighbor is foun...

Nowadays modern cars integrate advanced driving assistance systems which range up to fully automated driving modes. Since fully automated driving modes have not come into everyday practice yet, operators are currently making use of assistance systems. While still being in control of the vehicle, alerts signal possible collision dangers when, for example, parking. The reason for the necessity of...

Geometric Near-neighbor Access Tree (GNAT) is a metric space indexing method based on hierarchical hyperplane partitioning of the space. While GNAT is very efficient in proximity searching, it has a bad reputation of being a memory hog. We show that this is partially based on too coarse analysis, and that the memory requirements can be lowered while at the same time improving the search efficie...

We use household survey data from the UK to study how close ‘middle-aged’ men and women in partnerships live to their own parents and their partner’s parents. We find a slight tendency for couples to live closer to the woman’s parents than the man’s. This tendency is more pronounced among couples in which neither partner has a degree and in which there is a child. In other respects, proximity t...

This paper presents a new algorithm for real-time tracking of pairs of closest points as well as their corresponding surface features between certain general types of objects (which can be non-convex) with parametric curved surfaces. The fact that the algorithm works directly on accurate parametric descriptions of curved surfaces rather than polygonal approximation of surfaces (i.e., polygonal ...

A systematic study on $\alpha$-decay half-lives for the nuclei in range $93\leq Z \leq 118$ is done by employing various versions of proximity potentials. To obtain more reliable results, deformation terms are included up to hexadecapole ($\beta_{4}$) spherical-deformed nuclear and Coulomb interaction The favored $\alpha$-decays process this region categorized as even-even, odd A, odd-odd nucle...
