On a Result in Young's Quantitative Substitutional Analysis
In (4) Young investigates the representation in terms of his exact seminormal units m^ of substitutional expressions which are unchanged on premultiplication by any permutation of a given set of consecutive letters, or which are changed in sign on premultiplication by an odd permutation of those letters. He illustrates his results by deducing the forms of the matrices representing the positive ...
متن کاملSubstitutional Analysis of Orthologous Protein Families Using BLOCKS
Orthologous proteins, form due to divergence of parental sequence, perform similar function under different environmental and biological conditions. Amino acid changes at locus specific positions form hetero-pairs whose role in BLOCK evolution is yet to be understood. We involve eight protein BLOCKs of known divergence rate to gain insight into the role of hetero-pairs in evolution. Our procedu...
متن کاملSubstitutional effect on the transport properties of MnSi
We report the transport properties, including electrical resistivity (r) and Seebeck coefficient (S) of Ge-substituted MnSi1 xGex (with x 1⁄4 0, 0.02, 0.05, and 0.10) alloys as a function of temperature between 10 and 300K. It was found that the partial substitution of Ge at Si site has a surprisingly weak effect on the ferromagnetic transition temperature TC in MnSi, indicating that the negati...
متن کاملSubstitution Puzzles and Substitutional Semantics
Substitution failure is usually said to occur when a change from one co-referential name to another affects the truth value of the sentence. Taking the idea seriously that non-referring names like ‘Superman’ and ‘Clark Kent’ are indeed names and that they do not refer (to anything whatsoever), it is argued that the usual characterization does not only give rise to theories which inflate ontolog...
متن کاملEffect of substitutional doping on the Néel temperature of Cr2O3
First-principles calculations are used to explore the possibility of enhancing the Néel temperature T N of the magnetoelectric antiferromagnet Cr 2 O 3 by substitutional doping. We describe the electronic structure of transition metal (V, Ti, Mn, Fe, Co, and Ni) and anion (N and B) impurities and evaluate their effect on the exchange interaction. We find that, although transition-metal impuriti...
