We introduce a class of infinite words, called highly potential words because of their seemingly high potential of being a good supply of examples and counterexamples regarding various problems on words. We prove that they are all aperiodic words of finite positive defect, and having their set of factors closed under reversal, thus giving examples Brlek and Reutenauer were looking for. We prove...

Computational fixed point theorems can be used to automatically verify existence and uniqueness of a solution to a nonlinear system of n equations in n variables ranging within a given region of n-space. Such computations succeed, however, only when the Jacobi matrix is nonsingular everywhere in this region. However, in problems such as bifurcation problems or surface intersection problems, the...

the present article describes a case of prosthetic rehabilitation with the new technique of prefabricated osteo-cutaneous free fibula flap for reconstructing a maxillary defect which had resulted from ameloblastoma. the fibula and a cuff of 6-8 mm were prepared with its pedicle intact. the bone flap was left in place with its pedicle intact for 2 to 3 months; the skin graft and the flap were fr...

congenital left ventricular diverticulum is a rare cardiac malformation. two categories of congenital ventricular diverticulum have been identified with regard to their localization: apical and non-apical. apical diverticula are always associated with midline thoraco-abdominal defects and other heart malformations. non-apical diverticula are always isolated defects. diagnosis is established by ...

UNLABELLED 99mTc-DMSA late static planar imaging or SPECT is being used for the investigation of focal acute pyelonephritis (APN), especially in children with urinary tract infection (UTI). Diuretic 99mTc-mercaptoacetyltriglycine (MAG3) dynamic scintirenography has been applied in the evaluation of kidney function and structure, frequently to exclude obstruction. However, in children and adults...

UNLABELLED Many surgeons treat progressive femoral osteolysis in association with a well-fixed stem with bone grafting but in uncontained proximal defects the graft could get into the joint, raising a question regarding whether the osteolysis can be treated by simple débridement without bone grafting. We investigated whether the curetted proximal osteolysis around an unrevised femoral component...

This case report describes a 13-year-old boy with alveolar bony defect resulted from surgical removal of impacted upper canine transposed in the anterior region. The boy had a normal occlusion with malposition of upper central and lateral incisors. The treatment objectives were to align teeth, close spaces by mesial movement of the buccal segments in the upper jaw to repair bone loss. Fixed app...
