Step 2 often presents the main limitation for a pathway or a simple ON/OFF language as means to draw conclusions modeling approach. (lu.se)
The first model assessed the impact of the coordinated approach in a simulated network of 10 healthcare facilities, including 4 acute care hospitals (1 long-term acute care hospital (LTAC)) and 6 free-standing nursing homes serving adult patients. (cdc.gov)
The advantage of this modeling approach is that there is no limitation to fitting the model to the experimen- * tal data. (cdc.gov)
Photosynthesis, stomatal conductance and evapotranspiration follow the approach of the BIOME3 model, described in Haxeltine & Prentice (1996) . (lu.se)

Single cell sequencing combined with deep learning enables him to analyse and model differences between cells. (lu.se)

Forcing the model to use observed spikelet number and phenology and replacing the existing heat and cold subroutines improved accuracy of yield simulation from EF = −0.32 to EF =0.70 (EF is modelling efficiency). (plos.org)
Model efficiency was 0.14 with new heat and cold routines and improved to 0.48 when using new cardinal temperatures for phenology and early leaf growth. (plos.org)

The main causes of improved accuracy were that the new model subversions take into account transpirational cooling (which is high in arid environments) and early morning flowering for heat sterility, and minimum rather than average temperature for cold sterility. (plos.org)
Parameters reviewed included: sample container composition (amber glass and high-density linear polyethylene), head space composition (air or nitrogen), temperature (38C, 21C, and 5C), lighting (dark and diffuse sunlight), and catalytic species content. (epa.gov)

This code base should offer a support to apply our techniques to new datasets or utilize our fully trained models. (simtk.org)

With an appropriate adjustment to this key parameter, the excessive rainfall amount produced by the Emanuel scheme is reduced substantially. (confex.com)
The correlation between the modified Emanuel-simulated and Ethiopian station rainfall is quite strong (+0.66). (confex.com)

It consists of a musculo-skeletal body, whole body cutaneous receptors (tactile), uterus and amniotic fluid, neuronal model of spine and medulla, and a whole neocortex model with self-organizing neural network. (upenn.edu)

Uncertainties from model parameters and model discrepancy from small-scale models impact the accuracy and reliability of predictions of large-scale systems. (osti.gov)
Furthermore, we make testable predictions for further experiments. (lu.se)

Conclusions We have determined the accuracy of estimating energy expenditure with data-driven models that rely on ground reaction forces and muscle activity for three use cases. (simtk.org)
For experimental use cases where the accuracy of a data-driven model is sufficient and similar training data is available, standard indirect calorimetry could be replaced. (simtk.org)

Here we introduce artificial lattices made of lead halide perovskite nanocubes as a new platform to simulate and investigate the physics of correlated quantum materials. (lu.se)
In order to investigate this hypothetical scenario, we constructed a simulation model of a human fetus. (upenn.edu)

Extracting testable kinetic rate models from the experimental time traces is complicated by experimental shortcomings. (nature.com)

In this study, thermomechanical finite element models are used to evaluate how the stability of a glaciated volcano is impacted by variations in ice cap thickness, magma chamber depth, geometry, magma flux rate, and seasonal changes in ice cover thickness. (frontiersin.org)

Kojima and Yashiro ( 2005 ) established a method to evaluate the deformation characteristics of tunnel under the action of embankment and surface excavation through surface loading and unloading model test. (researchsquare.com)

The candidate particles, ranging from protons to nuclei as massive as iron, generate "extensive air-showers" (EAS) in interactions with air nuclei when en- tering the Earth's atmosphere. (lu.se)
Recently we have shown that a coarse-grained model based on the primitive model, that has been used for modelling polyelectrolytes for over 30 years, works well for a range of IDPs where electrostatics governs the intra- and intermolecular interactions [1]. (lu.se)

We demonstrate that optical injection of quantum confined excitons in this system realizes the two main features that ubiquitously pervade the phase diagram of many quantum materials: collective phenomena, in which long-range orders emerge from incoherent fluctuations, and the excitonic Mott transition, which has one-to-one correspondence with the insulator-to-metal transition described by the repulsive Hubbard model in a magnetic field. (lu.se)
Secondly, an adaptive feedforward plus feedback controller is designed and simulated as a preparation for the embedded system implementation. (intechopen.com)
This in vitro model system, by virtue of its simplicity and accessibility, provides a unique opportunity for examining the network effects of neuromodulation, as well as the underlying cellular mechanisms. (springer.com)
Our numerical experiments indicate that the presence of an ice cap (1-3 km thick) increases the average repose interval for a magma system. (frontiersin.org)
The infection is propagated through the virtual population through simulated social contacts, and the progress of the disease in infected individuals and their trajectory through the healthcare system is then simulated, based on public health data. (lu.se)

The goal of this research is to simulate solar wind effects on asteroid spectra through low energy 1 keV hydrogen ion irradiation of meteorite powder samples and measure the changes in their reflectance spectra. (helsinki.fi)
