Catch-Up: A Rule That Makes Service Sports More Competitive

Service sports include two-player contests such as volleyball, badminton, and squash. We analyze four rules, including the Standard Rule (SR), in which a player continues to serve until he or she loses. The Catch-Up Rule (CR) gives the serve to the player who has lost the previous point—as opposed to the player who won the previous point, as under SR. We also consider two Trailing Rules that ma...

Computational aspect to the nearest southeast submatrix that makes multiple a prescribed eigenvalue

Given four complex matrices $A$‎, ‎$B$‎, ‎$C$ and $D$ where $Ainmathbb{C}^{ntimes n}$‎ ‎and $Dinmathbb{C}^{mtimes m}$ and let the matrix $left(begin{array}{cc}‎ A & B ‎ C & D‎ end{array} right)$ be a normal matrix and‎ assume that $lambda$ is a given complex number‎ ‎that is not eigenvalue of matrix $A$‎. ‎We present a method to calculate the distance norm (with respect to 2-norm) from $D$‎ to ...

No-Prep Veneers: A New Ceramic Material That Makes Them a More Realistic Option

The ability to predictably bond thin pieces of tooth-colored restorative material to teeth and expect excellent long-term esthetic and functional results has created a new arena in the practice of dentistry — that of elective cosmetic treatment. This is not to say that these procedures “appeared overnight”; they did not. However, over the last 20 or so years, the materials and technologies have...
