The diffusion of small molecules in polymer matrices involves time scales (microseconds [μs] to milliseconds [ms]) far too long for routine molecular dynamics (MD) simulations. We have formulated a new method to extract coarse-grained information from short (1-2 nanoseconds [ns]) MD simulations and use this in a mesoscale simulation to calculate diffusion constants in polymer matrices. It uses ...

BACKGROUND Musculoskeletal pain is common in elderly persons. Analgesic use is high in the elderly and may involve unacceptable risk in individuals with chronic pain. Our aim was to compare the socio-demographic characteristics of elderly subjects with musculoskeletal disorders (MSD) and to assess medication use and clinical evolution of musculoskeletal pain according to physician prescribing p...

introduction the increasing practice of interventional fluoroscopy in diagnosis and treatment of cardiovascular disease has risen attention to improve radiation protection of patients and cardiologists in these relatively high dose techniques. therefore, nowadays there is an emphasis on the measurement of radiation dose received by patients and cardiologists arising from the relevant procedures...

• 2D split-ring resonator array with resonant frequency disorder. Localized modes and magnetic transport for uncorrelated correlated disorder in 2D. Correlated can create sub-diffusive propagation. We study the effect of a on eigenstates energy two-dimensional (square) resonators (SRRs). In absence disorder, we find dispersion relation magneto-inductive waves mean square displacement (MSD) clos...

In this paper, a novel distributed agent-based dynamical system estimation strategy is proposed. Each agent has a local observation space and is interested in a specific set of system state elements. The agents have the ability of two-way communication with its neighbors (i.e., agents who share at least one state element). At a particular time instant, each agent predicts its state and makes in...
