Spreadsheets can be viewed as a success story. Since the late seventies spreadsheet programs have been installed on the majority of computers and play a role comparable to text editors and databases management systems. Spreadsheets can be used to do anything with numbers, but are unable to handle process models and event data. Event logs and operational processes can be found everywhere. Recent...

abstract the supracondylar process is a beak-like bony projection that arises from the anteromedial surface of the humerus. the process has rarely been associated with compression of the median nerve and seldom requires treatment. we report a case of a supracondylar process that caused tenting of the median nerve with elbow extension and pronation.

MGS is an experimental programming language dedicated to the modeling and the simulation of a special kind of discrete dy- namical systems. Dynamical systems with a dynamical structure (or (DS)(2)) arise when the state space is not fixed a priori but is jointly computed with the current state during the simulation. In this case the evolution function is often given through local rules that driv...

Various interrelated issues that effect the reliability and efficiency of Newton-like methods for chemical process optimization are studied. An algorithm for solving large, sparse quadratic programming (QP) problems that is based on an active set strategy and a symmetric, indefinite factorization is presented. The QP algorithm is fast and reliable. A simple asymmetric trust region method is pro...

In this work, we predict a new physical phenomenon, induced fission-like process and chain reaction of hadronic molecular states. As state, if by $D$ meson, the $X(3872)$ can split into $D\bar{D}$ final state which is forbidden due to spin-parity conservation. The breeding meson reaction, such as $D^0X(3872)\to D^0\bar{D}^0D^0$, makes matter possible. We estimate cross section two mesons. With ...
