Classical dynamics as constrained quantum dynamics [PDF]
Journal of Physics A: Mathematical and General, 2003 We show that the classical mechanics of an algebraic model are implied by its quantizations. An algebraic model is defined, and the corresponding classical and quantum realizations are given in terms of a spectrum generating algebra. Classical equations of motion are then obtained by constraining the quantal dynamics of an algebraic model to an ...

Dynamic Ic and Dynamic Programming [PDF]
SSRN Electronic Journal, 2019 This paper develops a dynamic programming method when the one-stage deviation principle in the sense of mechanism design literature doesn’t hold. The commonly used dynamic programming method is valid only if the one-stage deviation principle in the sense of mechanism design literature is satisfied; it doesn't hold in every model, and the one-stage ...

Dynamic DNA Underpins Chromosome Dynamics [PDF]
Biophysical Journal, 2013 A recent article by Meyer and co-workers provides a detailed description of the dynamics of base-step conformational transitions and of the first steps to the basepair opening. These results underpin the essential role that DNA dynamics place in the DNA structural transitions that accompany the active processes of transcription, replication, and ...

Social force model for pedestrian dynamics. [PDF]
Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 1995 It is suggested that the motion of pedestrians can be described as if they would be subject to ``social forces.'' These ``forces'' are not directly exerted by the pedestrians' personal environment, but they are a measure for the internal motivations of ...

Psychosocial Outcomes in Patients With Endocrine Tumor Syndromes: A Systematic Review
Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction The combination of disease manifestations, the familial burden, and varying penetrance of endocrine tumor syndromes (ETSs) is unique. This review aimed to portray and summarize available data on psychosocial outcomes in patients with ETSs and explore gaps and opportunities for future research and care.

From molecular dynamics to Brownian dynamics [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2014 Three coarse-grained molecular dynamics (MD) models are investigated with the aim of developing and analysing multi-scale methods which use MD simulations in parts of the computational domain and (less detailed) Brownian dynamics (BD) simulations in the remainder of the domain. The first MD model is formulated in one spatial dimension.
