The structure of adsorbed cyclic chains

Journal of Molecular Modeling, 2015
In order to determine the structure of polymer films formed of cyclic chains (rings) we developed and studied a simple coarse-grained model. Our main goal was to check how the percolation and jamming thresholds in such a system were related to the thresholds obtained for linear flexible chains system, i.e., how the geometry of objects influenced both ...

Chemical structure of light chains

Proceedings of the Royal Society of London. Series B. Biological Sciences, 1966
Abstract The light chains of immunoglobulins are a heterogeneous population of peptide chains. Two general types can be recognized immunologically and chemically, the λ and the K light chains. But within the two types further heterogeneity has been demonstrated. A minor heterogeneity observed in the K chains has given rise to two main

Structured Markov chains solver

Proceeding from the 2006 workshop on Tools for solving sturctured Markov chains - SMCtools '06, 2006
We analyze the problem of the numerical solution of structured Markov chains encountered in queuing models: we describe the main computational problems and present the most advanced algorithms currently available for their solutions.

The structure of the chain of polyphenylacetylene

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1969
To elucidate the structure of the polymeric chain of polyphenylaeetylenes obtained b~polymerization in the catalytic system TiC1 + AI(C2Hs) 3 (Mn = 5100, 2600) and by thermal polymerization (M n = 1100), we carried out the ozonolysis of the polyphenylaeetylenes in CC14 solution at --30~ The ozonization products were oxidized to acids and these were ...

Structure of ricin A‐chain at 2.5 Å

Proteins: Structure, Function, and Bioinformatics, 1991
AbstractRicin has been refined in a crystallographic sense to 2.5 Å resolution and the model for the A‐chain (RTA) is described in detail. Because RTA is the first member of the class of plant toxins to be analyzed, this model probably defines the major structural characteristics of the entire family of these medically important proteins.

Mixed‐chain phospholipids: Structures and chain‐melting behavior

Lipids, 2001
AbstractIt has long been established that diacyl phospholipids isolated from animal cell membranes are predominantly of a mixed‐chain variety, meaning that the sn‐1 and sn‐2 acyl chains are saturated and unsaturated acyl chains, respectively. In general, monoenoic and dienoic acids are found in the sn‐2 acyl chain of phosphatidylcholine (PtdCho ...

Multilevel Solutions for Structured Markov Chains

SIAM Journal on Matrix Analysis and Applications, 2000
Summary: A new analysis approach for continuous time Markov chains (CTMCs) with a multidimensional structure is introduced. The presented solution technique employs the multidimensional structure to define aggregated CTMCs that can be analyzed more efficiently.

The structure of the I-measure of a Markov chain

IEEE Transactions on Information Theory, 1992
Summary: The underlying mathematical structure of Shannon's information measures was studied in a recent paper by Yeung, and the \(I\)-measure \(\mu^*\), which is a signed measure defined on a proper \(\sigma\)-field \({\mathcal F}\), was introduced. The \(I\)-measure is a natural extension of Shannon's information measures and is uniquely defined by ...
