By: N. Williams n, O. Wind-Willassen*, A. Wright n, R. Program*, J. Mehlsen *, J. Ottesen  n, M. Olufsen*

author keywords: cardiovascular system dynamics; head-up tilt; sensitivity analysis; subset selection; parameter estimation
MeSH headings : Adult; Blood Pressure / physiology; Blood Volume / physiology; Cardiac Output / physiology; Heart Rate / physiology; Homeostasis / physiology; Humans; Male; Mathematical Concepts; Models, Cardiovascular; Myocardial Contraction / physiology; Posture / physiology; Supine Position / physiology; Tilt-Table Test; Vascular Resistance / physiology
TL;DR: A patient-specific model that uses heart rate as an input to fit the dynamic changes in arterial blood pressure data during HUT is presented, which estimates physiologically reasonable values for arterial and venous blood pressures, blood volumes and cardiac output for which data are not available.

Antipathogen genes and the replacement of disease-vectoring mosquito populations: a model-based evaluation

Evolutionary Applications, 7(10), 1238–1251.

By: M. Robert  n, K. Okamoto  n, F. Gould  n & A. Lloyd n 

author keywords: Aedes aegypti; antipathogen genes; dengue fever; female-killing; ordinary differential equation model; reduce and replace
TL;DR: A mathematical model is utilized to evaluate impacts on competent Aedes aegypti populations of FK, AP, and R&R releases as well as hybrid strategies that result from combinations of these three approaches and discusses the roles that density dependence and inclusion of females play in the order of efficacy of the strategies.

THE EFFECT OF COHERENCE ON SAMPLING FROM MATRICES WITH ORTHONORMAL COLUMNS, AND PRECONDITIONED LEAST SQUARES PROBLEMS

SIAM JOURNAL ON MATRIX ANALYSIS AND APPLICATIONS, 35(4), 1490–1520.

By: I. Ipsen*  & T. Wentworth*

Contributors: I. Ipsen & T. Wentworth*

author keywords: condition number; singular values; leverage scores; sums of random matrices; majorization; preconditioning; QR factorization
TL;DR: A bound on the condition number of the sampled matrices in terms of the coherence $\mu$ of $Q$ is derived, which implies a, not necessarily tight, lower bound of $\mathcal{O}(m\mu\ln{n})$ for the number of sampled rows. (via Semantic Scholar)
