Published in 2017 at "Peptide Science"

DOI: 10.1002/bip.22997

Abstract: The present research investigates the identification of amino acid sequences that selectively bind to a pentaerythritol tetranitrate (PETN) explosive surrogate. Through the use of a phage display technique and enzyme‐linked immunosorbent assays (ELISA), a peptide… read more here.

Published in 2022 at "International Journal for Numerical Methods in Biomedical Engineering"

DOI: 10.1002/cnm.3575

Abstract: This work introduces a computational methodology to calibrate material models in biomechanical applications under uncertainty. We adopt a Bayesian approach, which estimates the probability distributions of hyperelastic material parameters, based on force‐strain measurements. We approximate… read more here.

Published in 2019 at "Journal of Cellular Biochemistry"

DOI: 10.1002/jcb.27790

Abstract: Allergic asthma is a lower respiratory tract disease of Th2 inflammation with multiple molecular mechanisms. The upper and lower airways can be unified by the concept of a united airway and, as such, gene expression… read more here.

Published in 2017 at "Statistics in medicine"

DOI: 10.1002/sim.7318

Abstract: Increasing attention has been focused on the use and validation of surrogate endpoints in cancer clinical trials. Previous literature on validation of surrogate endpoints are classified into four approaches: the proportion explained approach; the indirect… read more here.

Published in 2021 at "Statistics in medicine"

DOI: 10.1002/sim.9201

Abstract: A surrogate endpoint S in a clinical trial is an outcome that may be measured earlier or more easily than the true outcome of interest T. In this work, we extend causal inference approaches to… read more here.

Published in 2022 at "Statistics in Medicine"

DOI: 10.1002/sim.9602

Abstract: The primary benefit of identifying a valid surrogate marker is the ability to use it in a future trial to test for a treatment effect with shorter follow‐up time or less cost. However, previous work… read more here.

Published in 2017 at "Structural and Multidisciplinary Optimization"

DOI: 10.1007/s00158-016-1546-7

Abstract: Surrogate models are used to dramatically improve the design efficiency of numerical aerodynamic shape optimization, where high-fidelity, expensive computational fluid dynamics (CFD) is often employed. Traditionally, in adaptation, only one single sample point is chosen… read more here.

Published in 2019 at "Structural and Multidisciplinary Optimization"

DOI: 10.1007/s00158-018-2074-4

Abstract: The method of aggregating a large number of constraints into one or few constraints has been successfully applied to wing structural design using gradient-based local optimization. However, numerical difficulties may occur in the case that… read more here.

Published in 2019 at "Structural and Multidisciplinary Optimization"

DOI: 10.1007/s00158-019-02391-8

Abstract: In the expensive structural optimization, the data-driven surrogate model has been proven to be an effective alternative to physical simulation (or experiment). However, the static surrogate-assisted evolutionary algorithm (SAEA) often becomes powerless and inefficient when… read more here.

Published in 2019 at "Journal of Neurology"

DOI: 10.1007/s00415-019-09537-0

Abstract: Prion real-time quaking-induced conversion (RT-QuIC) is emerging as the most potent assay for the in vivo diagnosis of Creutzfeldt–Jakob disease (CJD), but its full application, especially as a screening test, is limited by suboptimal substrate… read more here.
