New Liquid Crystalline 2,5-Disubstituted 1,3-Dithians and 1,3-Dioxans

Abstract This paper describes the synthesis of new classes of liquid crystal materials based upon 2,5 -disubstituted 1,3- dioxans and 1,3-dithians.

Prospects for the design of new antiviral molecules: a chemist's view.

Most antiviral agents have been discovered by chance. These discoveries and the rationalization of their mode of action in terms of their selective action in the viral replicative cycle has demonstrated that viral targets exist. It is unlikely that in the near future that rational design will result in the synthesis of new classes of antiviral agents. Progress is more likely from a combination of the continuing identification of potential targets and the design of screens to identify prototype compounds, the properties of which may then be improved by chemical synthesis of analogues.

Optimal models for social change.

By assigning coordinates to the environmental function space comprising all physical and mental stimuli, mathematical interpretations can be based on such terms as adaptability, and reactivity which relate to individuals interacting with their environment within a society. These psychometric concepts are incorporated into a framework of functional analysis, which permits the optimization of social change by maximizing the satisfaction integral through the use of variational or dynamic programming methods in conjunction with some optimal social policy. The approach provides a mathematical connection between psychology and sociology, and further demonstrates that existing forms of government are simulated by differential equations belonging to the same general class. The synthesis of new classes of functional equations describing social progress is visualized as a legitimate objective for abstract mathematical sociology.
