“We have previously shown that inverse statistical-mechanical techniques allow the determination of optimized isotropic pair interactions that self-assemble into low-coordinated crystal configurations in the d-dimensional Euclidean space Rd. In some of these studies, pair interactions with multiple extrema were optimized. In the present work, we attempt to find pair potentials that might be easier to realize experimentally by requiring them to be monotonic and convex. Encoding information in monotonic convex potentials PF-6463922 mouse to yield low-coordinated ground-state configurations in Euclidean spaces is highly nontrivial. We adapt a linear programming method

and apply it to optimize two repulsive monotonic convex pair potentials, whose classical ground states are counterintuitively the square and honeycomb crystals in R(2). We demonstrate that our optimized pair potentials belong to two wide classes of

monotonic convex potentials whose ground states are also the GSK1120212 square and honeycomb crystal. We show that these unexpected ground states are stable over a nonzero number density range by checking their (i) phonon spectra, (ii) defect energies and (iii) self assembly by numerically annealing liquid-state configurations to their zero-temperature ground states. c 2011 American Institute of Physics.

“Objective: To develop a conceptual model to describe the burden of osteoarthritis in individuals with this condition and on the broader community.\n\nStudy Design and Setting: Six concept mapping workshops were undertaken: three with patients (n = 26) and three with health professionals (n = 27) in Australia and Sweden. The participants were asked to generate statements describing how osteoarthritis affects individuals with this condition and those around selleck compound them. The results were used to construct an integrated theoretical model of the personal burden of osteoarthritis (PBO) and its extended version, the personal and societal burden of osteoarthritis (PSBO) model.\n\nResults: We identified eight potentially independent

aspects of PBO, including physical distress, fatigue, physical limitations, psychosocial distress, physical deconditioning, financial hardship, sleep disturbances, and lost productivity. Physical distress and impaired physical function combined to produce psychosocial problems, reduced work productivity, financial difficulties, and loss of physical fitness at the individual level, and increased health and welfare cost at the societal level.\n\nConclusion: The PBO and PSBO models were developed directly from the views of patients and clinicians and provide new insights for managing the individual and societal burden of osteoarthritis.
