Computational cardiac physiology for new modelers: Origins, foundations, and future.

Publication Type: Academic Journal

Source(s): Acta physiologica (Oxford, England) [Acta Physiol (Oxf)] 2022 Oct; Vol. 236 (2), pp. e13865. Date of Electronic Publication: 2022 Aug 25.

Abstract: Mathematical models of the cardiovascular system have come a long way since they were first introduced in the early 19th century. Driven by a rapid development of experimental techniques, numerical methods, and computer hardware, detailed models that d...

Coexistence in diverse communities with higher-order interactions.

Publication Type: Academic Journal

Source(s): Proceedings of the National Academy of Sciences of the United States of America [Proc Natl Acad Sci U S A] 2022 Oct 25; Vol. 119 (43), pp. e2205063119. Date of Electronic Publication: 2022 Oct 17.

Abstract: A central assumption in most ecological models is that the interactions in a community operate only between pairs of species. However, two species may interactively affect the growth of a focal species. Although interactions among three or more species...

A Causal Framework for Distribution Generalization.

Publication Type: Academic Journal

Source(s): IEEE transactions on pattern analysis and machine intelligence [IEEE Trans Pattern Anal Mach Intell] 2022 Oct; Vol. 44 (10), pp. 6614-6630. Date of Electronic Publication: 2022 Sep 14.

Abstract: We consider the problem of predicting a response Y from a set of covariates X when test- and training distributions differ. Since such differences may have causal explanations, we consider test distributions that emerge from interventions in a structur...

Emergence of dynamic properties in network hypermotifs.

Publication Type: Academic Journal

Source(s): Proceedings of the National Academy of Sciences of the United States of America [Proc Natl Acad Sci U S A] 2022 Aug 09; Vol. 119 (32), pp. e2204967119. Date of Electronic Publication: 2022 Aug 01.

Authors:

Abstract: Networks are fundamental for our understanding of complex systems. The study of networks has uncovered common principles that underlie the behavior of vastly different fields of study, including physics, biology, sociology, and engineering. One of thes...

Facilitating behavior change: Introducing the Transtheoretical Model of Behavior Change as a conservation psychology framework and tool for practitioners.

Publication Type: Academic Journal

Source(s): Zoo biology [Zoo Biol] 2022 Sep; Vol. 41 (5), pp. 386-397. Date of Electronic Publication: 2022 May 24.

Abstract: The primary opportunities for improved conservation and sustainability outcomes are through changing human behavior. Zoos, aquariums, and other public-facing biodiversity conservation institutions offer an important space for environmental learning and...

A cancer model with nonlocal free boundary dynamics.

Publication Type: Academic Journal

Source(s): Journal of mathematical biology [J Math Biol] 2022 Oct 07; Vol. 85 (5), pp. 46. Date of Electronic Publication: 2022 Oct 07.

Abstract: Cancer cells at the tumor boundary move in the direction of the oxygen gradient, while cancer cells far within the tumor are in a necrotic state. This paper introduces a simple mathematical model that accounts for these facts. The model consists of can...

A mathematical model of discrete attachment to a cellulolytic biofilm using random DEs.

Publication Type: Academic Journal

Source(s): Mathematical biosciences and engineering : MBE [Math Biosci Eng] 2022 Apr 26; Vol. 19 (7), pp. 6582-6619.

Abstract: We propose a new mathematical framework for the addition of stochastic attachment to biofilm models, via the use of random ordinary differential equations. We focus our approach on a spatially explicit model of cellulolytic biofilm growth and formation...

Spatial Bayesian GLM on the cortical surface produces reliable task activations in individuals and groups.

Publication Type: Academic Journal

Source(s): NeuroImage [Neuroimage] 2022 Apr 01; Vol. 249, pp. 118908. Date of Electronic Publication: 2022 Jan 13.

Abstract: The general linear model (GLM) is a widely popular and convenient tool for estimating the functional brain response and identifying areas of significant activation during a task or stimulus. However, the classical GLM is based on a massive univariate a...

Simultant: simultaneous curve fitting of functions and differential equations using analytical gradient calculations.

Publication Type: Academic Journal

Source(s): BMC bioinformatics [BMC Bioinformatics] 2022 May 21; Vol. 23 (1), pp. 191. Date of Electronic Publication: 2022 May 21.

Authors:

Abstract: Background: The initial step in comparing mathematical models to experimental data is to do a fit. This process can be complicated when either the mathematical models are not analytically solvable (e.g. because of nonlinear differential equations) or w...
