Application and Evaluation of Surrogate Models for Radiation Source Search
ALGORITHMS, 12(12).
author keywords: surrogate modeling; bayesian inference; radiation source localization
TL;DR:
This work considers the problem of inferring the 2D location and intensity of a radiation source in an urban environment using a ray-tracing model based on Boltzmann transport theory, and considers surrogate models based on Legendre polynomials, multivariate adaptive regression splines, radial basis functions, Gaussian processes, and neural networks.

Within-host infectious disease models accommodating cellular coinfection, with an application to influenza
VIRUS EVOLUTION, 5(2).
author keywords: influenza virus; within-host dynamics; macroparasite model; cellular coinfection; viral complementation
TL;DR:
The within-host model structure developed here provides an alternative approach for modeling within- Host viral load dynamics and allows for a new class of questions to be addressed that consider the effects of cellular coinfection, collective viral interactions, and viral complementation in within- host viral dynamics and evolution.

Non-conventional therapeutic technique to replace CRISPR bacteria from biofilm by inducible lysogen
Ali, Q. (2019, March 15). JOURNAL OF BIOLOGICAL DYNAMICS, Vol. 13, pp. 151–178.
author keywords: Bacteria; bacteriophage; biofilm; CRISPR/Cas system; lysogen
MeSH headings : Algorithms; Bacteria / genetics; Biofilms / growth & development; Clustered Regularly Interspaced Short Palindromic Repeats / genetics; Lysogeny / genetics; Models, Biological
TL;DR:
The goal of this work is to find a suitable strategy which can eradicate bacteria with a CRISPR system through the influx of finite amounts of distinct lysogens over fixed intervals.

ROBUSTNESS OF THE SOBOL' INDICES TO DISTRIBUTIONAL UNCERTAINTY
INTERNATIONAL JOURNAL FOR UNCERTAINTY QUANTIFICATION, 9(5), 453–469.
author keywords: global sensitivity analysis; Sobol' indices; uncertain distributions; deep uncertainty
TL;DR:
The robustness of the Sobol' indices, a commonly used tool in GSA, to changes in the distribution of the uncertain variables is analyzed, which requires minimal user specification and no additional evaluations of the model.

Elimination-based certificates for triangular equivalence and rank profiles
JOURNAL OF SYMBOLIC COMPUTATION, Vol. 98, pp. 246–269.
author keywords: Interactive certificate; Rank profile; Linear algebra; Triangular equivalence; Verifiable computing
TL;DR:
Novel certificates for triangular equivalence and rank profiles are given, enabling somebody to verify the row or column rank profiles or the whole rank profile matrix faster than recomputing them, with a negligible overall overhead.

Stochastic Galerkin method for cloud simulation
Mathematics of Climate and Weather Forecasting, 5(1), 65–106.
TL;DR:
A stochastic Galerkin method is developed for a coupled Navier-Stokes-cloud system that models dynamics of warm clouds to explicitly describe the evolution of uncertainties that arise due to unknown input data, such as model parameters and initial or boundary conditions.

Real-time implementation and analysis of a modified energy based controller for the swing-up of an inverted pendulum on a cart
EUROPEAN JOURNAL OF CONTROL, 50, 176–187.
author keywords: Inverted pendulum; Energy based control; Lyapunov functions; Real-time implementation
TL;DR:
A modified energy based swing-up controller using Lyapunov functions is derived using a more complex dynamical model for the single inverted pendulum (SIP) system than the simplified model that is most commonly used.

Revisiting Normalized Gradient Descent: Fast Evasion of Saddle Points
IEEE Transactions on Automatic Control, 64(11), 4818–4824.
author keywords: Gradient methods; machine learning; nonconvex optimization; optimization
TL;DR:
A global convergence-time bound is established for NGD under mild assumptions because it is shown that NGD “almost never” converges to saddle points and the time required to escape from a ball of radius is small.
