Abstract Background: Successful clinical decisions are the outcome of a complex process. In making them, we draw on information from scientific evidences, our personal experience and external rules and constraints. Considering that the explosive increase in the amount and quality of the scientific evidence that has come from both the laboratory bench and the bedside, we may lack the time, mo...
The overarching purpose of the group’s studies lies in elucidating the variety of ways in which materials and structures accommodate deformation and carry load at different scales and levels of organisation. To this end, mechanical microscopy is underpinned by multi-scale simulation using analytical and numerical methods and drawing on advanced finite element modelling, dislocation dynamics, mo...
Technical reports from the Automatic Control group in Linkping are available by anonymous ftp at the address ftp.control.isy.liu.se. This report is contained in the compressed postscript le 2026.ps.Z. Abstract This paper deals with a new method for closed loop identiication, i.e. the projection method. This method generalizes the already known two-stage method by allowing the estimation of non-...
A vector field splitting approach is discussed for the systematic derivation of numerical propagators for deterministic dynamics. Based on the formalism, a class of numerical integrators for Langevin dynamics are presented for single and multiple time step algorithms.
abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...
Current network modeling practices usually assess the network performance at specified time interval, i.e. every 5 or 10 years time horizon. Furthermore, they are usually based on partially predictable data, which are being generated through various stochastic procedures. In this research, a new quantitative based methodology which combines combinatorial optimization modeling and transportation...
As part of an international intercomparison project, the weak temperature gradient (WTG) and damped gravity wave (DGW) methods are used to parameterize large-scale dynamics in a set of cloud-resolving models (CRMs) and single column models (SCMs). The WTG or DGW method is implemented using a configuration that couples a model to a reference state defined with profiles obtained from the same mod...

We consider spin systems on the integer lattice graph Z with nearest-neighbor interactions. We develop a combinatorial framework for establishing that exponential decay with distance of spin correlations, specifically the strong spatial mixing condition (SSM), implies rapid mixing of a large class of Markov chains. As a first application of our method we prove that SSM implies O(log n) mixing o...
The neural dynamics of the nematode C. elegans are experimentally low-dimensional and correspond to discrete behavioral states, where previous modeling work has found neural proxies for some of these states. Experimental results further suggest that dynamics may be understood as longtimescale transitions between multiple low-dimensional attractors. To identify multistable regimes of our model, ...
