Abstract Circular dichroism (optical activity) can only be observed for chiral molecules or in the case of molecule-ligand binding only if at least one of the interacting species is chiral. This is usually true in biochemistry particularly if a biological macromolecule such as a protein/peptide is involved.

This 13-year-old girl presented with several days’ history of anorexia, cough and pleuritic chest pain. She had no significant medical history. On examination, she was dehydrated, tachycardic and had a temperature of 39.5°C, but there were no chest signs on examination.

Current Opinion in Structural Biology, 1996
During 1994 and 1995, the structures of the serum amyloid P component, the bacterial chaperonin GroEL, the 20S proteasome, the bacterial light-harvesting complexes and the tryptophan operon RNA-binding attenuation protein have been determined. These structures all form circular assemblies in which the individual subunits are related by rotational ...

IEE Proceedings - Systems Biology, 2006
The problem of disentangling complex dynamic systems is addressed, especially with a view to identifying those variables that take part in the essential qualitative behaviour of systems. The author presents a series of reflections about the methods of formalisation together with the principles that govern the global operation of systems. In particular,

Proceedings of the 14th annual Southeast regional conference on - ACM-SE 14, 1976
We define a finite-state machine called a circular automata (CA) which processes information in a queue; we show that any function computed (or any language recognized) by such a machine is computable (recognizable) by a Turing machine and vice versa. Space and time bounds are given for the needed simulations.

Computer-Aided Design, 1992
A circular spline is a \(C^ 1\) curve consisting of circular arcs which join at the knots \(P_ 1,\dots,P_ n\). The author considers the problem of interpolating a given point set (open or closed) in \(\mathbb{R}^ 2\) and \(\mathbb{R}^ 3\) by circular splines with knots at the interpolation points.

IEEE Computer Graphics and Applications, 1998
The author discusses two interesting relationships between circles and lines. There should be a computer graphics application that can use the first topic to run faster or better. The second topic is Ptolemy's Theorem, which is a generalization of the triangle inequality. The author shows how it can be used to derive the angle addition formulas.

Journal of Philosophy, 2007
The common claim that the notion of collective action must figure in the content of the attitudes of the parties to a collective action gives rise to a circularity challenge. Standard responses to this challenge are criticized. This article’s solution exploits a notion of collectivity that does not presuppose intention: a purely causal conception that ...
