Classical and quantum structuralism [article]

A salient feature here is the graphical calculus for categorical quantum mechanics, which allows a purely diagrammatic representation of classical-quantum interaction.  ...  Grothendieck) with the categorical presentations of quantum states, provides a resource sensitive account of various quantum-classical interactions: of classical control of quantum data, of classical data  ...  Previous structural models for quantum-classical interaction required either additional completeness assumptions, most notably biproducts, to model quantum spectra [AC04, Sel04, Sel07] , or a second monoidal  ...

Acetylcholinesterase: 'classical' and 'non-classical' functions and pharmacology

Israel Silman, Joel L Sussman
2005 Current opinion in pharmacology (Print)  
It is anchored within the synaptic cleft by a highly specialized anchoring device in which catalytic subunit tetramers assemble around a polyproline II helix.  ...  In addition, AChE is believed to play 'non-classical' roles in addition to its 'classical' role in terminating synaptic transmission (e.g. as an adhesion protein).  ...  Acknowledgements The authors acknowledge the support of the Kimmelman Center for Biomolecular Structure and Assembly (Rehovot, Israel), the Benoziyo Center for Neurosciences, the US Army Medical and Material  ...

Classical Be Stars

John M. Porter, Thomas Rivinius
2003 Publications of the Astronomical Society of the Pacific  
This variation for at least some of these objects has been shown to be due to nonradial pulsation. For at least one star, evidence for a magnetic field has been observed.  ...  Recent results for classical Be stars are reviewed and links to general astrophysics are presented.  ...  McDavid et al. (2000) , modeling polarimetric data, required a spiral structure, rather than a plainly radial "arm," to explain phase lags in 48 Lib between Ha observations (scanning the outer parts of  ...

CLASSICISM AND NEO-CLASSICISMS IN THE HISTORY OF MUSIC

Gabriel BULANCEA, Dunarea de Jos University of Galati, Romania
2021 International Multidisciplinary Scientific Conference on the Dialogue between Sciences & Arts Religion & Education  
"The mistake of neo-classicism, with its statues painted or sculpted based and antique models, is Orpheus' mistake.  ...  Neo-classicism represents the happiest mixture between past and present, that form of artistic reverberation in which modernity still makes room for the seal of the past.  ...  fine sense of humour which confers him a certain objectivity, allowing him a chance of ensuring a recipe for success.  ...

Why Is Classical Theory Classical?

R. W. Connell
1997 American Journal of Sociology  
The Rules became a must-read classic, for the first time, half a century after it was published.  ...  In Weimar Germany, from different starting points, Max Scheler and Karl Mannheim converged on a "sociology of knowledge,'' the object of fierce controversy for a short period.  ...

Classical Be stars

Thomas Rivinius, Alex C. Carciofi, Christophe Martayan
2013 The Astronomy and Astrophysics Review  
This is not only true for the disk structure, but as well for its variability, both cyclic and secular.  ...  In the past decade, a consensus has emerged regarding the nature of classical Be stars: They are very rapidly rotating main sequence B stars, which, through a still unknown, but increasingly constrained  ...  Mota, Coralie Neiner, Atsuo Okazaki, Stan Owocki, Gail Schaefer, and Richard Townsend for providing data for figures.  ...

Nonlinear Classical Fields [article]

V. Radchenko
2019 arXiv   pre-print
We regard a classical field as a medium and so the additional parameter, the velocity of a field,appears.  ...  If the one regard as a potential of same field then the self-energies of the fields became finite. Electromagnetic, mechanical, pionic, and somewhat gluonic fields are regarding  ...  In our model the structure of 6Li is reverse because the spectral data strongly support such structure. The things did not have to be so simple as the table shown.  ...

Chemometrics: From classical to genetic algorithms

Riccardo Leardi
2002 Grasas y Aceites  
While the noise reduction is a common goal for any data set, the relevance of the reduction of the number of variables in the final model depends very much on the kind of data constituting the data set  ...  In that case, if the percentage of missing data is quite high, the whole data set is not suitable for a multivariate analysis; as a consequence, the variables and/or the objects with the lowest number  ...

Confining classical configurations

A. González-Arroyo, A. Montero
1997 Nuclear Physics B - Proceedings Supplements  
We construct a family of smooth, almost self-dual, non-thermalized SU(2) gauge field configurations, and measure the average of the fundamental, adjoint and spin 3/2 representation Wilson loops on them  ...  This is precisely what we would expect from a classical model like ours.  ...  Furthermore, we suggested that in this situation fractional topological charge objects begin to be identifiable structures and form a liquid, which explains many properties of the Yang-Mills vacuum, and  ...
