Conspectus Quantum mechanics (QM) has revolutionized our understanding of the structure and reactivity of small molecular systems. Given the tremendous impact of QM in this research area, it is attractive to believe that this could also be brought into the biological realm where systems of a few thousand atoms and beyond are routine. Applying QM methods to biological problems brings an improved...

Quadriceps myopathy (QM) is a rare form of muscle disease characterized by pathological changes predominately localized to the quadriceps. Although numerous inheritance patterns have been implicated in QM, several QM patients harbor deletions in dystrophin. Two defined deletions predicted loss of functional spectrin-like repeats 17 and 18. Spectrin-like repeat 17 participates in actin-filament ...

the increasing emphasis on supply chain management (scm) has led researchers to rethink models, constructs, and frameworks for quality management (qm) that have been developed for the field of operations management. in this paper, within the framework of a structural model we investigate how these two supply chain management-related quality practices (customer focus and supplier quality managem...

Michigan State University Quality Matters: Teaching Tools MSU has a campus subscription to QM. This page provides information for creating a personal QM account in order to make full use of the QM rubric and online resources to create and assess improved online education and student learning. Also offers links to other technology tools for teaching available at MSU. https://tech.msu.edu/teachin...

We obtain a generalization of Furstenberg’s Diophantine Theorem on non-lacunary multiplicative semigroups. For example we show that the sets of sums {(p1 qm 1 + p2 qm 2 )α : n, m ∈ N} and {(p1 qm 1 + 2n)α : n, m ∈ N} are dense in the circle T = R/Z for all irrational α, where (pi, qi) are distinct pairs of multiplicatively independent integers for i = 1, 2.

Quality management (QM) systems have been developed and used by many in the construction industry to ensure right things are done and things are done right the first time. However, current quality systems are designed to monitor and control the “production process” of a specific organization, with the QM data being revealed to the accreditation bodies during the auditing process only. As great ...

Kohn-Sham density functional theory (KS-DFT)[1, 2] is an efficient and usefully accurate electronic structure method, because it replaces the interacting Schrödinger equation with a set of single-particle orbital equations. Calculations with several hundred atoms are now routine, but there is always interest in much larger systems. Many such systems are treated by a lower-level method, such as ...

We show that there are significant conceptual differences between QM and QFT which make it difficult to view QFT as just a relativistic extension of the principles of QM. The root of this is a fundamental distiction

The oxy-myoglobin (Mb-O2) structure was probed by QM/MM (hybrid quantum mechanical/ molecular mechanical) calculations using DFT/MM to elucidate the effect of the heme propionates and the protein matrix on the chemistry of heme Fe-O2 moiety. On this line, we have probed the role of His97 in various protonation states of the heme propionate-6.
