Mechanically bonded macromolecules constitute a class of challenging synthetic targets in polymer science. The controllable intramolecular motions of mechanical bonds, in combination with the processability and useful physical and mechanical properties of macromolecules, ultimately ensure their potential for applications in materials science, nanotechnology and medicine. This tutorial review de...

In recent years audio tactile diagrams have emerged as a viable method of providing blind learners with access to diagrammatical material. It has proven beneficial, but obstacles remain to its widespread adoption, especially in situations where a teacher may not be skilled in tactile production. Current approaches to audio tactile production contain limitations in various areas namely reusabili...

The temperature phase transition in scalar φ4(x) field theory with spontaneous symmetry breaking is investigated in a partly resummed perturbative approach. The second Legendre transform is used and the resulting gap equation is considered in the extrema of the free energy functional. It is found that the phase transition is of first order in the super daisy as well as in a certain beyond super...

This paper presents Daisy, a scalable all-optical packet network where each node is equipped with one wavelength-tunable transmitter and one fixed-wavelength receiver. Network scalability is obtained with a novel multifiber ring topology that allows spatial reuse of wavelengths and requires an optical transmitted power proportional typically to the square root of the number of nodes. The scalab...
