Near Field Communication (NFC) is a short-range contactless communication standard recently emerging as cashless payment technology. However, NFC has been proved vulnerable to several threats, such as eavesdropping, data modification, and relay attacks. A relay attack forwards the entire wireless communication, thus communicating over larger distances. In this paper, we review and discuss feasi...

The permutation based algorithm has been proved unbeatable in high dimensional spaces, requiring O(|P|) distance evaluations when solving similarity queries (where P is the set of permutants); but needs n evaluations of the permutant distance to compute the order to review the metric dataset, requires O(n|P|) space, and does not take much benefit from low dimensionality. There have been several...

So far, methods for ellipsis and anaphor resolution have been developed and the effects of anaphor resolution have been analyzed in the context of statistical information retrieval (IR) of scientific abstracts. No significant improvement has been observed. In this study, the effects of ellipsis and anaphor resolution on proximity searching in a full text database are analyzed. Anaphora and elli...

We integrate insights from the social embeddedness perspective with research on immigrant entrepreneurship to theorize on how family resources influence exit from entrepreneurship among previously unemployed immigrant entrepreneurs. Results from a cohort study of immigrant entrepreneurs in Sweden reveal that family resources are important for immigrants to integrate economically into a country....

The nearest point problem (NPP), i.e., finding the closest points between two disjoint convex hulls, has two classical solutions, the Gilbert–Schlesinger–Kozinec (GSK) and Mitchell–Dem’yanov–Malozemov (MDM) algorithms. When the convex hulls do intersect, NPP has to be stated in terms of reduced convex hulls (RCHs), made up of convex pattern combinations whose coefficients are bound by a mo1 val...

Abstract International fabrication codes and standards provide minimum distance criteria for proximity welds, although rigorous justification is lacking. These distances are either based on practical experience or mutual agreement often left to the engineering judgment of contractors, inspection engineers, etc., especially in cases repair welds fabricated existing welds. Previous studies have s...

PURPOSE To identify the specific radiographic signs on orthopantomograms that are positive predictors of intraoperative inferior dental nerve (IDN) exposure and postoperative IDN deficit in lower third molar surgery. MATERIALS AND METHODS A prospective clinical cohort of patients with lower third molars with specific radiographic signs showing a close proximity of the roots to the IDN who und...

The average distance of a vertex $v$ of a connected graph $G$is the arithmetic mean of the distances from $v$ to allother vertices of $G$. The proximity $pi(G)$ and the remoteness $rho(G)$of $G$ are defined as the minimum and maximum averagedistance of the vertices of $G$. In this paper we investigate the difference between proximity or remoteness and the classical distanceparameters diameter a...

BACKGROUND The purpose of this study was to use panoramic radiographic findings to predict postsurgical sensory impairment following the extraction of impacted mandibular third molars. METHODS There were 120 patients enrolled in this study (55 male and 65 female). A total of 120 impacted mandibular third molars were included due to the proximity between the inferior alveolar nerve (IAN) canal...
