We present a theoretical analysis of lasing action in photonic crystal surface-emitting lasers (PCSELs). The semiclassical laser equations for such structures are simulated with three different theoretical techniques: exact finite-difference time-domain calculations, an steady-state ab-initio laser theory and a semi-analytical coupled-mode formalism. Our simulations show that, for an exemplary ...
OBJECTIVE The authors describe the complexity of social processes for implementing technological change. Once a new technology is available, information about its availability and benefits must be made available to the community of users, with opportunities to try the innovations and find them worthwhile, despite organizational resistances. METHOD The authors reviewed the literature from psyc...
Multidisciplinary techniques, in particular the combination of theoretical and experimental immunology, can address questions about human immunity that cannot be answered by other means. From the turnover of virus-infected cells in vivo, to rates of thymic production and HLA class I epitope prediction, theoretical techniques provide a unique insight to supplement experimental approaches. Here w...
The polarisation of prompt ψ(2S) mesons is measured by performing an angular analysis of ψ(2S) → μ + μ − decays using proton-proton collision data, corresponding to an integrated luminosity of 1.0 fb −1 , collected by the LHCb detector at a centre-of-mass energy of 7 TeV. The polarisation is measured in bins of transverse momentum p T and rapidity y in the kinematic region 3.5 < p T < 15 GeV/c ...
An appreciation of the extraordinarily rich dynamics of cardiac arrhythmias can be obtained from examination of any text in electrocardiography. Typically, there are a large number (100 or more) of rhythms that are identified on the basis of changes outside of normal limits of rhythm and wave morphology in the electrocardiogram.’*’ The point of this paper is to show that mathematics can provide...
In this work, the concept of complex modeling (CM) is tested by carrying out a co-refinement of the atomic pair distribution function and small-angle X-ray scattering data from CdS nanoparticles. It is shown that, compared with either single technique alone, the CM approach yields a more accurate and robust structural insight into the atomic structure and morphology of nanoparticles. This work ...
Large biological molecules are frequently represented by a single three-dimensional structure, but in reality, under physiological conditions, they are dynamic entities in constant motion. One important theoretical technique for analyzing both motions and energetics and the roles they play in macromolecular structure and function is a form of simulation termed molecular dynamics. The field of o...
We introduce the Anharmonic Oscillator Symmetry Model to describe vibrational ex-citations in molecular systems exhibiting high degree of symmetry. A systematic procedure is proposed to establish the relation between the algebraic and configuration space formulations , leading to new interactions in the algebraic model. This approach incorporates the full power of group theoretical techniques a...
BACKGROUND The translation of healthcare research into practice is typically challenging and limited in effectiveness. The Theoretical Domains Framework (TDF) identifies 12 domains of behaviour determinants which can be used to understand the principles of behavioural change, a key factor influencing implementation. The Accelerated Chest pain Risk Evaluation (ACRE) project has successfully tran...
How do we interpret findings that are intriguing, potentially important, but not statistically significant? We discuss in the context of a series of papers in the Journal of Theoretical Biology that reported evidence that beautiful parents have more daughters, violent men have more sons, and other sex-ratio patterns (Kanazawa, 2005, 2006, 2007). These papers have been shown to have statistical ...
