A new data assimilation procedure to develop a debris flow run-out model [PDF]

open access: yes, 2015
Parameter calibration is one of the most problematic phases of numerical modeling since the choice of parameters affects the model\u2019s reliability as far as the physical problems being studied are concerned. In some cases, laboratory tests or physical

Spin-label Order Parameter Calibrations for Slow Motion [PDF]

open access: yesApplied Magnetic Resonance, 2017
Abstract Calibrations are given to extract orientation order parameters from pseudo-powder electron paramagnetic resonance line shapes of 14N-nitroxide spin labels undergoing slow rotational diffusion. The nitroxide z-axis is assumed parallel to the long molecular axis.

Evaluation of in vitro toxicity of common phytochemicals included in weight loss supplements using 1H NMR spectroscopy

open access: yesFEBS Open Bio, EarlyView.
We investigated the toxicity of 12 active compounds commonly found in herbal weight loss supplements (WLS) using human liver and colon cell models. Epigallocatechin‐3‐gallate was the only compound showing significant toxicity. Metabolic profiling revealed protein degradation, disrupted energy and lipid metabolism suggesting that the inclusion of EGCG ...

Traffic microsimulation for smart cities: Investigating the impact of objective function formulation on calibration efficiency

open access: yesIET Smart Cities
Traffic microsimulation models are crucial for intelligent transportation systems evaluation, but careful parameter calibration is required for credible pre‐ and post‐ITS comparisons.

Parameter Subset Selection for Power System Model Calibration Using Both Sensitivity and Identifiability

open access: yesIEEE Access
In power systems, it is essential to ensure that the dynamic model predictions align with the actual measurements, which is usually achieved through model calibration.

Multi-Objective Calibration For Agent-Based Models [PDF]

open access: yes, 2004
Agent-based modelling is already proving to be an immensely useful tool for scientific and industrial modelling applications. Whilst the building of such models will always be something between an art and a science, once a detailed model has been built ...

Selecting parameters for Bayesian calibration of a process-based model: a methodology based on canonical correlation analysis [PDF]

open access: yes, 2013
Bayesian statistics is becoming increasingly common in the environmental sciences because of developments in computers and sampling-based techniques for parameter estimation.

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

open access: yesFEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

Prediction Model for Etiologic Differentiation of Isolated Vestibular Syndrome in Emergency Settings

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective This study aimed to develop and validate a predictive model for differentiating central from peripheral etiologies in patients with isolated vestibular syndrome (VS). Methods In this multicenter retrospective cohort study, 506 patients with isolated VS from five hospitals were divided into derivation (n = 301) and validation (n = 205)
