A review of endodontic and periodontal aspects on the prognosis, diagnosis, prevention, and treatment of accidental root perforations is presented. Successful treatment depends mainly on proper diagnosis and immediate sealing of the perforation to eliminate risk of infection. A classification of root perforations is presented in the review to assist the clinician in making a proper choice of tr...

This paper proposes an automatic method of reading proper names with multiple pronunciations. First, the method obtains Web pages that include both the proper name and its pronunciation. Second, the method feeds them to the learner for classification. The current accuracy is around 90% for open data.

It is shown using a space-time curvature classification and decomposition that for certain holonomy types of a space-time, proper projec-tive vector fields cannot exist. Existence is confirmed, by example, for the remaining holonomy types. In all except the most general holon-omy type, a local uniqueness theorem for proper projective symmetry is established.

In his 1998 paper, Ryan classified the sets of unit, proper, and plain trapezoid and parallelogram orders. We extend this classification to include unit, proper, and plain triangle orders. We prove that there are 20 combinations of these properties that give rise to distinct classes of ordered sets, and order these classes by containment.

Introduction Automatic human emotion recognition is one of the most interesting topics in the field of affective computing. However, development of a reliable approach with a reasonable recognition rate is a challenging task. The main objective of the present study was to propose a robust method for discrimination of emotional responses thorough examination of heart rate variability (HRV). In t...

Proper consistency is defined by the properties that each player takes all opponent strategies into account (is cautious) and deems one opponent strategy to be infinitely more likely than another if the opponent prefers the one to the other (respects preferences). When there is common certain belief of proper consistency, a most preferred strategy is properly rationalizable. Any strategy used w...

A 3-graph is a cubic graph endowed with a proper edge colouring in three colours. Surfaces can be modelled by means of 3-graphs. We show how 3-graphs can be used to establish the standard classification of sUrfaces by orientability and Euler characteristic. In [8], Tutte approaches topological graph theory from a combinatorial viewpoint. In particular, an entirely combinatorial approach to the ...
