Structural characterization of glycoproteins
Journal of Chromatography A, 1988The structural characterization of glycoproteins by high-performance liquid chromatography (HPLC) is often difficult because of microheterogeneity of their oligosaccharide groups. To investigate this phenomenon, a series of human plasma glycoproteins of known amino acid sequence and carbohydrate structure was subjected to comparative study by HPLC ...

Characterization of MagFET structures
2008 15th IEEE International Conference on Electronics, Circuits and Systems, 2008The paper deals with characterization of various MagFET structures in alternating magnetic field in frequency range from 10 Hz to 10 kHz. 3D numerical simulation of MagFET structures has been used to investigate influence of MagFET geometry to the magnetic field sensitivity.

An Exact Characterization of Greedy Structures
SIAM Journal on Discrete Mathematics, 1993Summary: The authors present exact characterizations of structures on which the greedy algorithm produces optimal solutions. Our characterization, which are called matroid embeddings, complete the partial characterizations of \textit{R. Rado} [Note on independent functions, Proc. London Math. Soc., III. Ser. 7, 300-320 (1957; Zbl 0083.023)], \textit{D.

Structural and Thermodynamic Characterization of Polyphenylbenzenes
The Journal of Physical Chemistry A, 2011The thermodynamic and structural study of a series of polyphenylbenzenes, from benzene, n(Ph) = 0, to hexaphenylbenzene, n(Ph) = 6, is presented. The available literature data for this group of compounds was extended by the determination of the relevant thermodynamic properties for 1,2,4-triphenylbenzene, 1,2,4,5-tetraphenylbenzene, and ...

Characterization of Linear Structures
Designs, Codes and Cryptography, 2001Let \(F\) be a function defined from \(F_2^m\) to \(F_2^n\) and \((\alpha,a)\) be an element of \(F_2^m\times F_2^n\), with \(\alpha\neq 0\). Then \((\alpha,a)\) is defined to be a linear structure of \(F\) if \(F(x)= F(x+\alpha)+ a\) for all \(x\in F_2^m\).

On Characterization of Chemical Structure
Journal of Chemical Information and Computer Sciences, 1997We briefly review characterization of chemical structure as evolving from the early work on the connectivity index to the latest work on a characterization of 3-D structures, including characterization of the folding of model proteins.

Coinductive characterizations of applicative structures
Mathematical Structures in Computer Science, 1999We discuss new ways of characterizing, as maximal fixed points of monotone operators, observational congruences on λ-terms and, more generally, equivalences on applicative structures. These characterizations naturally induce new forms of coinduction principles for reasoning on program equivalences, which are not based on Abramsky's applicative ...

On Characterization of Cyclic Structures
Journal of Chemical Information and Computer Sciences, 1997We consider a characterization of cyclic structures based on the information from graph distance matrix, D, and detour matrix, DD, of a graph. Using the elements of D and DD matrices we have constructed a new matrix D/DD, the elements of which are given as a quotient of the corresponding elements of D and DD matrices. The sum of all entries of a matrix

Functional and structural characterization of a heparanase
Nature Chemical Biology, 2015We report the structural and functional characterization of a novel heparanase (BpHep) from the invasive pathogenic bacterium Burkholderia pseudomallei (Bp), showing ∼24% sequence identity with human heparanase (hHep). Site-directed mutagenesis studies confirmed the active site resi-dues essential for activity, and we found that BpHep has specificity ...

Systolic structures: A notion and characterization
Journal of Parallel and Distributed Computing, 1986A notion of systolicity based on embeddability of processing structures is introduced. This notion characterizes the systolic structures that can be extended to solve problems of larger size, without a corresponding increase in processing time. A mathematical model for specifying such extendable structures is developed.
