The Structure of Qualitatively Determinate Relationships

Econometrica, 1983
This paper presents the necessary and sufficient conditions for determining the signs of the solution variables of a system of linear equations based only upon a knowledge of the signs of the coefficient matrix and the signs of the "right hand side" variables.

Determination of Antibody Structures

2014
While antibodies share a conserved structural framework, their complementarity-determining region loops are highly variable in size and sequence. Even more variable are the potential ways these loops can be used to interact with antigen. Thus, X-ray crystal structures of antibody Fab fragments and Fab-antigen complexes are critical for a detailed ...

Structure determination

2020
This chapter discusses the interpretation of NMR spectra to deduce the structure of the compound. When analysing an NMR spectrum, we should consider the groups of spins present, not individual spins. It is important to look for symmetrical patterns to identify the chemical shifts (the number of chemically different groups of spins of the nuclide ...

Determination, Determinability, and the Structure of Ens

2018
This chapter takes us into the fundamental elements of Baumgarten’s metaphysical system, the concepts of “determination” and “determinability,” and shows how his specific formulation of these concepts was fateful for the development of later German philosophy.

Structural Determinants of Enzymic Processivity

Biochemistry, 1994
A processive enzyme binds a polymeric substrate and catalyzes a series of similar chemical reactions along that polymer before releasing the fully modified polymer to solvent. Bovine pancreatic ribonuclease A (RNase A) is a nonprocessive endoribonuclease that binds the bases of adjacent RNA residues in three enzymic subsites: B1, B2, and B3.

Structural determinants of glomerular permeability

American Journal of Physiology-Renal Physiology, 2001
Recent progress in relating the functional properties of the glomerular capillary wall to its unique structure is reviewed. The fenestrated endothelium, glomerular basement membrane (GBM), and epithelial filtration slits form a series arrangement in which the flow diverges as it enters the GBM from the fenestrae and converges again at the filtration ...

Helical assemblies: Structure determinants

Journal of Theoretical Biology, 2015
Protein structural motifs such as helical assemblies and α/β barrels combine secondary structure elements with various types of interactions. Helix-helix interfaces of assemblies - Ankyrin, ARM/HEAT, PUM, LRR, and TPR repeats - exhibit unique amino acid composition and patterns of interactions that correlate with curvature of solenoids, surface ...
