Let A be a C*-algebra with identity and suppose A has real rank 0. Suppose a complex-valued function is holomorphic and bounded on the intersection of the open unit ball of A and the identity component of the set of invertible elements of A. We show that then the function has a holomorphic extension to the entire open unit ball of A. Further, we show that this does not hold when A = C(S), where...

Let G be a 4-connected graph. For an edge e of G, we do the following operations on G: first, delete the edge e from G, resulting the graph G e; second, for all vertices x of degree 3 in G e, delete x from G e and then completely connect the 3 neighbors of x by a triangle. If multiple edges occur, we use single edges to replace them. The final resultant graph is denoted by G e. If G e is 4-conn...

PATIENT A 39-year-old female patient was admitted with mobility of maxillary anterior fixed partial denture. She was diagnosed as severe chronic periodontitis of abutment teeth of the denture, left alveolus cleft, and anterior/posterior crossbites. The crossbites were improved by prosthetic approach using an implant-supported fixed partial denture with a removable gingival veneer at the anterio...

Anterior crossbite correction in early mixed dentition is highly recommended as this kind of malocclusion do not diminish with age. Uncorrected anterior crossbite may lead to abnormal wear of the lower incisors, dental compensation of mandibular incisors leading to thinning of labial alveolar plate and/or gingival recession. There are several methods for solving this problem. In this article we...

Email systems and removable storage devices are the two most popular and user-friendly mechanisms of file exchange that provide privacy preserving and security for data communication. Most previous work has focused on mitigating external attacks on data communication by improving data encryption and integrity techniques. In this paper, we present a novel anonymization-based framework (Stenog-Sh...

Implants have been designed to provide edentulous patients with fixed prostheses or overdentures. Recently, implant-supported fixed partial prostheses and single crowns have become successful treatment alternatives to removable and fixed partial dentures. However, few researchers have examined "removable partial dentures on implants and natural teeth". In this article, we report two patients fi...

It is well known that for a first order system of linear difference equationswith rational function coefficients, a solution that is holomorphic in some le‰ half plane can be analytically continued to a meromorphic solution in the whole complex plane. Œe poles stem from the singularities of the rational function coefficients of the system. Just as for differential equations, not all of these si...

OBJECTIVE To evaluate the effects of space maintainers on plaque accumulation, periodontal health and oral microflora. SUBJECTS AND METHODS The study participants comprised 38 patients aged 4-10 years requiring either fixed or removable space maintainers. Plaque index, gingival index, bleeding on probing index, candidal colonization and Enterococcus faecalis were recorded just before the appl...

This paper surveys some recent results on existence, uniqueness and removable singularities for fully nonlinear differential equations on manifolds. The discussion also treats restriction theorems and the strong Bellman principle.
