Geometry concurrency

The training of a GCS takes place concurrently with the evolution of its geometry. The adjustment of the node weights resembles the equivalent process in the SOM, but some extra bookkeeping is needed so that, when the time comes to expand the network by adding a unit, the new unit can be inserted into the network at the position in which it can be of the greatest benefit. In summary, the GCS algorithm is as follows ... 

A counterpoise-corrected geometry optimization (with concurrent optimization of the intramolecular geometry) requires minimization of Eq. (5). To date, no automated counterpoise-corrected optimization algorithms based on Eq. (5) have... 

Starch can readily be modified by concurrent heat, application of moisture, and pressure. Such modifications may be conducted in extruders. Low moisture content favors formation of water-soluble starch with increased water-binding capacity, 65a 65e The solubility, water binding-capacity, and viscosity of gels prepared from extruded starch do not show linear relationships against either the moisture content in starch or the extrusion temperature.65c-65f Such extruder variables as the type of screw (either single or twin), pattern of the barrel and die heating, screw velocity, and geometry of the screw thread are also essential factors.65 ... 

Analysis of the intimate mechanism for conversion of L M-(tj2-HC=CH) to LnM=C=CH2 suggests that the reaction most likely involves initial slippage of the acetylene from an tj2- to an tj1-binding mode. In this geometry, positive charge develops on the j8 carbon, and hydrogen transfer in a 1,2-hydride shift type mechanism with concurrent...
