Symmetric designs on Lie algebras and interactions of hamiltonian systems. [PDF]

open access: yes, 1994
Nonhamiltonian interaction of hamiltonian systems is considered. Dynamical equations are constructed by use of symmetric designs on Lie algebras. The results of analysis of these equations show that some class of symmetric designs on Lie algebras beyond ...

Higher complement C4 gene copy number constitutes a shared genetic risk factor for giant cell arteritis and IgA vasculitis

open access: yesArthritis &Rheumatology, Accepted Article.
Objective Low copy number (CN) of complement C4 isoforms and high CN of retroviral HERV‐K elements are known risk factors for many immune‐mediated inflammatory diseases (IMIDs), often showing sex‐biased effects. Here, we assessed whether CN variation within the C4 gene contributes to giant cell arteritis (GCA) and IgA vasculitis (IgAV), two complex ...

From the Equations of Motion to the Canonical Commutation Relations

open access: yes, 2010
The problem of whether or not the equations of motion of a quantum system determine the commutation relations was posed by E.P.Wigner in 1950. A similar problem (known as "The Inverse Problem in the Calculus of Variations") was posed in a classical ...

Opposing consensus science through scholarly practices: The role of claims maintenance

open access: yesJournal of the Association for Information Science and Technology, EarlyView.
Abstract This study examines how three US‐based communities who oppose consensus science produce and disseminate scholarly‐like artifacts: pro‐life activists, Young Earth Creationists, and Anthropogenic Climate Crisis skeptics. Prior research shows that industry‐ or church‐backed advocacy campaigns often generate claims supported by these communities ...

Towards a definition of quantum integrability

open access: yes, 2008
We briefly review the most relevant aspects of complete integrability for classical systems and identify those aspects which should be present in a definition of quantum integrability. We show that a naive extension of classical concepts to the quantum

Making teaching an attractive profession: What are the challenges and opportunities for minority ethnic teachers in England?

open access: yesBritish Educational Research Journal, EarlyView.
Abstract This paper explores the challenges and opportunities surrounding the recruitment and retention of minority ethnic teachers in England. Drawing on interview data from 33 teachers and school leaders of diverse ethnic backgrounds, it investigates whether racialised barriers identified in earlier research have shifted in the current context of ...

Special Jordan subspaces in Coupled Cell Networks [PDF]

open access: yes, 2013
Given a regular network (in which all cells have the same type and receive the same number of inputs and all arrows have the same type), we define the special Jordan subspaces to that network and we use these subspaces to study the synchrony phenomenon ...

‘Fish in simulated water’? A Bourdieusian analysis of Chinese doctoral students' learning experiences in Southeast Asian developing countries

open access: yesBritish Educational Research Journal, EarlyView.
Abstract International student mobility (ISM) has historically followed a pattern of movement from developing regions to developed countries. However, in recent years, there has been a noticeable increase in the number of Chinese students pursuing doctoral studies in Southeast Asian developing countries, an area that has received relatively little ...

‘When joy comes your way, you have to grab it!’ Troubling how queer joy features in the lives of LGBT+ school‐attending youth in South Africa

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Recently, the concept ‘queer joy’ has gained interest in LGBT+ scholarship in the West. I use this scholarship as an entry point to explore how school‐attending LGBT+ youth express joy and how joy serves as a form of resistance against gender and sexuality norms in educational settings.

Real points of coarse moduli schemes of vector bundles on a real algebraic curve [PDF]

open access: yes, 2011
We examine a moduli problem for real and quaternionic vector bundles on a smooth complex projective curve with a fixed real structure, and we give a gauge-theoretic construction of moduli spaces for semi-stable such bundles with fixed topological type ...
