The de Bruijnâ€“Tengbergenâ€“Kruyswijk (BTK) construction is a simple algorithm that produces an explicit symmetric chain decomposition of a product of chains. We linearize the BTK algorithm and showâ€¦ (More)

OBJECTIVE
The aim of this review was to test the hypothesis that 6 mm micro-rough short Straumann(Â®) implants provide predictable survival rates and verify that most failures occurring are earlyâ€¦ (More)

This study aimed to compare the trueness of one type of CAD/CAM milled complete removable dental prostheses (CRDPs) with injection-molding and conventionally manufactured CRDPs. Thirty-three CRDPsâ€¦ (More)

The degree partition of a simple graph is its degree sequence rearranged in weakly decreasing order. Let DP(n) (respectively, DS(n)) denote the convex hull of all degree partitions (respectively,â€¦ (More)

OBJECTIVE
This systematic review was performed to compare the survival of 1- vs. 2-implant overdentures (IODs) in the edentulous mandible.

Consider a graph whose edges have been colored red and blue. Assign a nonnegative real weight to every edge so that at every vertex, the sum of the weights of the incident red edges equals the sum ofâ€¦ (More)

We inductively construct an explicit (common) orthogonal eigenbasis for the elements of the Bose-Mesner algebra of the Grassmann scheme. The key step is a constructive, linear algebraicâ€¦ (More)
