Structure of ‘Complex’ Phospholipids
Nature, 1963RECENTLY, Collins has described the presence of ‘complex’ phospholipids in animal tissues1,2. These compounds are shown to be very sensitive towards silicic acid and other mild hydrolytic reagents. This characteristic is believed to be the reason why other workers failed to detect the ‘complex’ phospholipid fraction, since chromatography over silicic ...

Structurally Reinforced Tetraazamacrocyclic Complexes
Inorganic Chemistry, 2000The reaction between alkyl or aryl aldehydes and macrocyclic ligands with pendant amine groups produced imidazolidine-containing bi- or tricyclic ligands. The copper complexes of three of these ligands were structurally characterized: [CuL3Cl].3H2O (triclinic, P1, a = 10.041(2) A, b = 10.172(1) A, c = 11.202(1) A, alpha = 92.07(1) degrees, beta = 96.76(

Evolutionary Synthesis of Complex Structures
2008 19th International Conference on Database and Expert Systems Applications, 2008Synthesis, identification and control of the complex systems is usually extremely complicated. When classics methods are used, also some simplifications are done which leads to idealized solutions that are far away of reality. In the contrary, class of method based on evolutionary principles, is successfully used to solve this kind of problems with ...

Structure of the haptoglobin–haemoglobin complex
Nature, 2012Red cell haemoglobin is the fundamental oxygen-transporting molecule in blood, but also a potentially tissue-damaging compound owing to its highly reactive haem groups. During intravascular haemolysis, such as in malaria and haemoglobinopathies, haemoglobin is released into the plasma, where it is captured by the protective acute-phase protein ...

Structural Complexity and Neural Networks
2002We survey some relationships between computational complexity and neural network theory. Here, only networks of binary threshold neurons are considered.We begin by presenting some contributions of neural networks in structural complexity theory. In parallel complexity, the class TCk0 of problems solvable by feed-forward networks with k levels and a ...
