Thorough medical and dental examinations were performed and findings were in accordance with the typical features...

In this paper, a visible and removable watermarking scheme in JPEG compression is presented. In the scheme, a secure template is generated to modulate the embedding strength of watermark and host image, separately. The template generates different versions of watermarked images which can be seen visually the same, and the visible watermark can only be removed by the user using the correct key. ...

Removable dentures are commonly used in routine dental practice at older ages. Accidental swallowing of various numbers of teeth has been reported in the literature before. However, total swallowing of removable mandibular prostheses in this size is a very rare emergency. In this study, we reported a case of accidental ingestion of a partially removable mandibular prosthesis and its final passi...

The lower bound on the length of 'removable' cycles in Theorem 1 is essentially best possible since there exist 2-connected simple graphs of minimum degree k whose longest 'removable' cycle has length k + i. Moreover, for the special case k = 4, we can construct 2-connected, 4-regular simple graphs whose longest 'removable' cycle has length four. The following counterexample which was independe...

AIM This study was aimed at evaluating the quality of written prescriptions for fixed and removable prosthesis in Tabriz, northwest Iran.
