This paper reports the management of two clinical cases, in which the upper right central incisor was fused with a supernumerary tooth and the upper left central incisor was macrodontic. A radiographic examination revealed that the fused teeth had two separate roots. Hemisectioning of the fused teeth was performed, the supernumerary portion was extracted and the remaining part was reshaped to r...

We derive upper and lower bounds on the smallest and largest eigenvalues, respectively, of real symmetric Toeplitz matrices. The bounds are rst obtained for positive-deenite matrices and then extended to the general real symmetric case. Our bounds are computed as the roots of rational and polynomial approximations to spectral, or secular, equations. The decomposition of the spectrum into even a...

The success of endodontic treatment not only lies in meticulous cleaning, perfect shaping and precise filling of canels, it also embodies vital importance on familiarity of unusual root canal patterns. This article presents a case report of a maxillary first molar that had two separate palatal roots with distinct canals and also an invitro assessment of an extracted tooth which had a a similar ...

This paper describes a modular connectionist model of the acquisition of receptive in ectional morphology. The model takes inputs in the form of phones one at a time and outputs the associated roots and inections. Simulations using arti cial language stimuli demonstrate the capacity of the model to learn su xation, pre xation, in xation, circum xation, mutation, template, and deletion rules. Se...

The connection between the festival of Pesaḥ-Maṣṣot and Israelites’ exodus from Egypt is a cornerstone Jewish identity religious practice which has its roots in calendars Pentateuch (Exod. 12–13; Exod. 23; Lev. Deut. 16). However, closer investigation shows that texts question differ considerably both with respect to characteristics etiological exodus. present paper focuses particularly on comp...
